Description

Lifting casting line

Technical Field

The present application relates to the technical field of casting pouring equipment, in particular to a lifting pouring line.

Background Art

Bottom casting refers to a method of pouring in which a liquid outlet is provided at the bottom of the ladle and a pouring port is connected to the top of the sand mold.

Generally speaking, a production line produces more than one specification of sand molds, and sand molds of different specifications may have different heights. Therefore, in order to ensure that the liquid outlet is aligned with the pouring port, conventional pouring machines are usually equipped with pads, which are used to raise all sand molds to the same height of the pouring port.

Due to the different heights of the sand mold, the pads need to be raised to different heights. For this reason, conventional casting machines make the pads adjustable in height, or allow the pads to be spliced and the number of spliced pads to be changed to meet the requirements of different heights.

This means that conventional casting lines need to prepare a work station for assembling the pads before casting, and also need to assemble the pads and sand molds additionally, which is time-consuming and labor-intensive.

Furthermore, the assembly transfer vehicle includes: a receiving platform for receiving sand molds or cushion blocks; an extractor for receiving the sand molds on the receiving platform; a lifting drive for driving the extractor to perform lifting movements; when combining the sand molds and cushion blocks, a sand mold enters the receiving platform, the extractor receives the sand mold, and carries the sand mold up under the drive of the lifting drive, so that a cushion block enters the receiving platform; after the cushion block enters the receiving platform and is under the sand mold, the lifting drive drives the extractor to descend, so that the sand mold can be stacked on the cushion block.

Furthermore, the pouring roller is extended along the first direction and can receive multiple groups of sand molds at the same time; the pouring section also includes a first group of driving mechanisms, which are used to drive the gantry to move along the first direction so that the pouring ladle can pour the sand molds on the pouring roller one by one.

Furthermore, the pouring section includes two pouring rollers, either one of which is extended along a first direction, and the two pouring rollers are arranged side by side along a second direction, and the first direction is perpendicular to the second direction.

Furthermore, along the second direction, the gantry is arranged across the two casting rollers; the casting section also includes a second set of driving mechanisms, which are used to drive the lifting driving mechanism to move along the second direction on the gantry, so as to facilitate the casting ladle to cast the sand molds on the two casting rollers.

Furthermore, a working platform is provided on the gantry, on which workers can operate the ladle, thereby manually controlling the ladle to release liquid; a safety railing is provided on the working platform, and the safety railing can be raised and lowered; when the worker controls the ladle to release the pouring solution, the safety railing rises to protect the worker.

DETAILED DESCRIPTION

In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

The present application provides a lifting pouring line, including: a storage section 100, used to store sand molds 1 and cushion blocks 2 to be poured; a pouring section 200, used to pour the sand molds 1; an assembly transfer vehicle 300, which docks the storage section 100 and the pouring section 200, and can input the sand molds 1 to be poured into the pouring section 200, or can first assemble the sand molds 1 to be poured onto the cushion blocks 2, and then input the assembled sand molds 1 into the pouring section 200.

It should be noted that stacking the sand mold 1 on the cushion block 2 can raise the sand mold 1 and increase the position of the pouring port on the top of the sand mold 1 so that the pouring port is within the pouring height range of the pouring section 200 .

Generally, the production line will produce sand molds 1 of various specifications, and sand molds 1 of different specifications may have different heights. It is easy to understand that if the sand mold 1 with a higher height already meets the condition that "the pouring port is within the pouring height range of the pouring section 200", it is not necessary to install the cushion block 2 before pouring. Correspondingly, if the sand mold 1 does not meet the condition that "the pouring port is within the pouring height range of the pouring section 200", it is necessary to install the cushion block 2 before pouring.

Therefore, in the present application, the assembly transfer vehicle 300 has two functions: one is to transfer the sand mold 1, and the other is to raise the sand mold 1 as needed.

Specifically, when the sand mold 1 to be poured meets the condition that "the pouring port is within the pouring height range of the pouring section 200", the assembly transfer vehicle 300 can directly input the sand mold 1 into the pouring section 200 after receiving the sand mold 1 from the storage section 100, and the pouring operation is completed by the pouring section 200. If the sand mold 1 to be poured does not meet the condition that "the pouring port is within the pouring height range of the pouring section 200", the assembly transfer vehicle 300 needs to receive the sand mold 1 and the cushion block 2 from the storage section 100 respectively, and stack the sand mold 1 on the cushion block 2 to raise the sand mold 1, and then input the sand mold 1 into the pouring section 200, and the pouring operation is completed by the pouring section 200.

To meet the needs of use, the assembly transfer vehicle 300 includes a conveying part and an assembly part, the conveying part is used to realize the transmission of the sand mold 1, and the assembly part is used to stack the sand mold 1 on the pad 2; wherein, the conveying part can adopt an AGV trolley, a rail car, a motorized roller conveyor, etc., and the assembly part can adopt a robot, a stacking clamp, etc., and the present application does not limit the specific configuration of the assembly transfer vehicle 300; the present application does not limit the specific configuration of the assembly transfer vehicle 300.

More specifically, the pouring section 200 includes: a pouring roller 210 for receiving the sand mold 1; a gantry 220 straddling the pouring roller 210 and for placing the ladle 3; and a lifting drive mechanism 230 disposed on the gantry 220 and for driving the ladle 3 to perform lifting movements.

During the pouring process of the lifting pouring line provided in the present application, the ladle 3 can move in the vertical direction driven by the lifting drive mechanism 230, thereby adjusting the height of the liquid outlet at the bottom of the ladle 3 so that the liquid outlet can approach and align with pouring ports at different heights.

Among them, the pouring roller 210 can adopt a passive roller. At this time, the pouring roller 210 includes a plurality of rollers arranged in sequence, each of which is rotatably set on a support; after the first sand mold 1 is sent into the pouring roller 210 by the assembly transfer vehicle 300, as the second sand mold 1 enters, the second sand mold 1 can push the first sand mold 1, so that the first sand mold 1 moves downstream... and so on, by continuously allowing new sand molds 1 to enter the pouring roller 210, the sand molds 1 already on the pouring roller 210 are gradually pushed away, thereby realizing the pouring roller 210 to transport the sand molds 1.

Alternatively, the pouring roller 210 may be a motorized roller. In this case, the pouring roller 210 includes a plurality of rollers arranged in sequence, all of which are linked together, and when one of the rollers is driven to rotate by a driving member (such as an electric motor, etc.), all of the rollers rotate in the same direction under the drive of the linkage mechanism, thereby actively conveying the sand mold 1.

The gantry 220 is configured in a door shape, including two groups of support columns 223 and two beams 224 erected on the top of the two groups of support columns 223. The pouring roller 210 is located between the two groups of support columns 223, and the beam 224 is suspended above the pouring roller 210. When the gantry 220 places the ladle 3, the ladle 3 is located between the two beams 224 and suspended above the pouring roller 210, so that the liquid outlet at the bottom of the ladle 3 is aligned with the pouring port at the top of the sand mold 1.

The lifting drive mechanism 230 can be driven by an electric cylinder, an oil cylinder or the like. The lifting drive mechanism 230 is arranged on the beam 224, and the movable end of the lifting drive mechanism 230 is connected to the ladle 3. The ladle 3 can be lifted and lowered according to the height of the sand mold 1 to be poured so that the distance between the liquid outlet and the pouring port is within a preset range, thereby ensuring the accuracy of pouring and avoiding the splashing of the high-temperature pouring solution.

Optionally, the storage section 100 stores sand molds 1 of various specifications, but only stores cushion blocks 2 of one specification.

Since the pouring section 200 is provided with a lifting drive mechanism 230 so that the ladle 3 can be lifted and lowered, the present application does not rely on the cushion block 2 , which is only used to meet the pouring needs of the sand mold 1 of extremely small specifications.

Therefore, the pad block 2 is configured according to the height of the smallest sand mold 1 in the production line to ensure that the sand mold 1 with the smallest height meets the condition of "the pouring port is within the pouring height range of the pouring section 200" after being raised. All sand molds 1 can choose whether to assemble the pad block 2 as needed, and finally all can be within the pouring range of the ladle 3.

Different from the traditional pouring line that completely relies on the pad 2 for elevation, the lifting pouring line provided in the present application no longer needs the design of strengthening the pad 2. It only uses one specification of pad 2 and ensures that the pad 2 of this specification can raise the sand mold 1 with the smallest height in the production line to meet the condition that "the pouring port is within the pouring height range of the pouring section 200". This can ensure that all sand molds 1 can be accurately and reliably poured.

At the same time, since the lifting drive mechanism 230 is used to drive the ladle 3 to do lifting movement, the lifting drive mechanism 230 has a small load and a fast response speed. In addition, except for a few sand molds 1 with low heights that require additional assembly of pads 2, most sand molds 1 no longer need to assemble pads 2, and can be directly cast by lifting the ladle 3. The selective assembly of pads 2 is beneficial to the casting efficiency of the ladle 3.

The lifting pouring line provided in the present application realizes the rapid pouring of the sand mold 1 by providing a lifting pouring section 200 with a pouring ladle 3 and cooperating with an assembly transfer vehicle 300. When necessary, the sand mold 1 can be raised with a cushion block 2, thereby improving the applicability of the entire line.

To facilitate the storage of materials, the storage section 100 includes a storage warehouse 110 , and the storage warehouse 110 includes at least one layer of storage rooms.

Among them, the storage warehouse 110 can be set up as an ordinary platform for placing sand molds 1 or cushion blocks 2; it can also be set up in the form of multiple single rooms, each single room independently storing a sand mold 1 or a cushion block 2; it can also be set up in the form of a roller conveyor to facilitate the movement of sand molds 1 or cushion blocks 2.

This application does not limit the specific configuration of the storage library 110 .

The storage warehouse 110 includes two or more layers of storage rooms, and can fully utilize the height space of the factory building to achieve high stacking and layered storage of materials.

Optionally, a plurality of motorized rollers are provided in the storage room, and the plurality of motorized rollers are arranged in sequence to cooperate in receiving and conveying the sand mold 1 or the cushion block 2 .

1 and 2 , in the illustrated embodiment, the storage section 100 includes two groups of storage bins 110, and the two groups of storage bins 110 are arranged side by side along the second direction; any group of storage bins 110 includes three layers of storage rooms, and each layer of storage rooms is extended along the first direction; each layer of storage rooms is provided with a motorized roller conveyor line extending along the first direction; a motorized roller conveyor line includes a plurality of groups of motorized roller conveyors sequentially arranged along the first direction; the sand mold 1 or the cushion block 2 is placed on the motorized roller conveyor; when the rollers of the motorized roller conveyor are not rotating, the sand mold 1 or the cushion block 2 is stored in the storage room; when the rollers of the motorized roller conveyor rotate, the sand mold 1 or the cushion block 2 is transported to the assembly transfer vehicle 300.

A motorized roller conveyor is arranged in the storage room, and the storage section 100 can conveniently receive and output materials through its own structure.

It should be noted that, since the motorized roller conveyor can only output materials in a straight line, it is preferred that a storage room on one floor only stores cushion blocks or only stores sand molds 1 of the same specification, thereby ensuring that the assembly transfer vehicle 300 can pick up the required materials at any time.

Optionally, the storage section 100 includes two groups of storage bins 110 , wherein one group of storage bins 110 is used to store the sand molds 1 to be poured, and the other group of storage bins 110 is used to store the cushion blocks 2 .

By setting up two groups of storage bins 110, classified storage of sand molds 1 and cushion blocks 2 is achieved. In this way, on the one hand, it is convenient to count the storage status of sand molds 1 and cushion blocks 2 in the storage section 100. On the other hand, since the sand mold 1 is configured with cushion blocks 2 on demand, classified storage can avoid the cushion blocks 2 interfering with the output of the sand mold 1 that does not need to be raised when the two are stored in the same warehouse. On the other hand, in the production line, the cushion blocks 2 are reused. After the sand mold 1 is poured, the cushion blocks 2 used to raise it will be transmitted back to the storage section 100 through the transfer line and wait for the next use. Therefore, the conveying path of the cushion blocks 2 is different from the conveying path of the sand mold 1 to be poured. Storing the sand mold 1 and cushion blocks 2 in different storage bins 110 can avoid interference between their conveying paths.

Of course, if necessary, the storage unit 100 may also include three or even more groups of storage bins 110 to meet more diverse storage needs.

It is easy to understand that when the storage warehouse 110 includes multiple layers of storage rooms, it is difficult for the assembly transfer vehicle 300 designed on the flat ground to access the materials in the upper storage rooms.

In one embodiment, the material receiving platform of the assembly transfer vehicle 300 can be raised and lowered, so that the material receiving platform is raised to the storage room of the corresponding layer to receive the required materials. Then, the material receiving platform is lowered and the assembly transfer vehicle 300 can be cast in the casting section 200 to realize the transfer of materials.

In another embodiment, the storage warehouse 110 includes at least two layers of storage rooms; the storage section 100 also includes a transfer cart 120, which can be docked with any layer of storage rooms to facilitate the receipt of the sand mold 1 or the cushion block 2. The transfer cart 120 can also be docked with the assembly transfer cart 300 to facilitate the transfer of the sand mold 1 or the cushion block 2.

Specifically, the transfer vehicle 120 includes: a transfer receiving platform 121, which is used to connect the storage room and the assembly transfer vehicle 300 to realize the transfer of materials; and a transfer lifting drive mechanism 122, which is used to drive the transfer receiving platform to move up and down so that the transfer receiving platform can connect to the storage rooms on different levels. The transfer lifting drive mechanism 122 can adopt a linear drive mechanism such as an electric cylinder and a module.

Specifically, please refer to Figure 2. In the illustrated embodiment, the transfer material receiving platform 121 uses a group of motorized rollers. When the transfer material receiving platform 121 is docked with the storage room, it can dock with the motorized roller line in the storage room, so that the motorized rollers of the transfer material receiving platform 121 and the motorized roller line rotate in the same direction, and the transfer material receiving platform 121 can receive the material; when the transfer material receiving platform 121 is docked with the pouring roller 210, the motorized rollers of the transfer material receiving platform 121 rotate in the opposite direction, and the material can be input into the pouring roller 210.

Continuing with reference to Figure 2, the transfer trolley 120 also includes a mounting bracket 123, which is frame-shaped and has a certain height. The transfer material receiving platform 121 is slidably arranged in the mounting bracket 123 and can be lifted and lowered in the vertical direction along the mounting bracket 123; the transfer lifting drive mechanism 122 includes two groups of drive cylinders, which are arranged on both sides of the mounting bracket 123 along the second direction and are respectively connected to one end of the transfer material receiving platform 121. The two groups of drive cylinders can act synchronously to drive the transfer material receiving platform 121 to rise or fall stably.

Optionally, the storage section 100 includes two groups of storage bins 110, which are arranged side by side along the second direction; the storage section 100 also includes two groups of transfer carts 120, and a group of transfer carts 120 are provided at the output end of any storage bin 110. Each group of transfer carts 120 can independently lift and receive materials of the required layer, and dock and assemble the transfer cart 300 to realize material transfer.

Optionally, the storage section 100 includes a plurality of groups of storage bins 110, which are spaced apart along the second direction; the storage section 100 also includes a group of transfer carts 120, which can move along the second direction (such as by providing electric cylinders, modules and other driving parts, or by providing walkable wheels); in this way, the transfer cart 120 can dock with different storage bins 110 by translation.

Optionally, two preparation platforms are provided downstream of the transfer vehicle 120 , wherein one preparation platform is used to store the sand mold 1 , and the other preparation platform is used to store the cushion block 2 , and the preparation platforms are used to dock and assemble the transfer vehicle 300 .

When transferring materials, the transfer vehicle 120 docks with the storage warehouse 110, obtains the required sand mold 1 or cushion block 2, and then places the sand mold 1 or cushion block 2 into the corresponding preparation platform, waiting to be picked up by the assembly transfer vehicle 300.

A preparation platform is provided so that the transfer cart 120 can take out the required materials in advance; when the assembly transfer cart 300 is moving and assembling materials, the transfer cart 120 can also receive new materials; this is conducive to improving the transfer efficiency of materials.

Optionally, the preparation platform adopts a motorized roller conveyor, which can actively receive or output materials when in operation.

In one embodiment, the assembly transfer vehicle 300 includes: a receiving platform 310 for receiving the sand mold 1 or the cushion block 2; an extractor 320 for receiving the sand mold 1 on the receiving platform 310; a lifting drive 330 for driving the extractor 320 to perform lifting movements; when the sand mold 1 and the cushion block 2 are combined, a sand mold 1 enters the receiving platform 310, the extractor 320 receives the sand mold 1, and carries the sand mold 1 up under the drive of the lifting drive 330, so that a cushion block 2 enters the receiving platform 310; after the cushion block 2 enters the receiving platform 310 and is located under the sand mold 1, the lifting drive 330 drives the extractor 320 to descend, so that the sand mold 1 is stacked on the cushion block 2.

4 , in the illustrated embodiment, the assembly transfer vehicle 300 further includes an assembly bracket 340, which is frame-shaped and has a certain height. The material receiving platform 310 is fixedly arranged at the bottom of the assembly bracket 340 for receiving the sand mold 1 or the cushion block 2; the material receiving platform 310 adopts a motorized roller conveyor, which can actively receive or output the material through the rotation of the roller; the extraction member 320 includes two sets of fork plates, which are spaced apart along the second direction and are respectively slidably arranged on one side of the assembly bracket 340, and the fork plates can be moved along the assembly bracket 340. 0 moves in the vertical direction; the lifting drive member 330 includes four groups of rack assemblies, and the four groups of rack assemblies are arranged at four corners; a pair of gears of any group of rack assemblies are arranged opposite to each other in the vertical direction; a fork plate is provided on the rack of any group of rack assemblies; the lifting drive member 330 also includes two linkage shafts and two motors, wherein two groups of rack assemblies are connected in series by one linkage shaft, and the other two groups of rack assemblies are connected in series by another linkage shaft, and each linkage shaft is driven by a motor; after the motor drives the gears to rotate, the four groups of chains rotate synchronously to drive the fork plate to rise or fall.

In one embodiment, the assembly transfer vehicle 300 is arranged between the storage section 100 and the pouring section 200, and one side of the assembly transfer vehicle 300 is connected to the output end of the storage section 100, and the other side is connected to the input end of the pouring section 200; at this time, the assembly transfer vehicle 300 can realize the transfer of the sand mold 1 without translation.

In another embodiment, referring to FIG. 1 , the storage section 100 and the pouring section 200 are arranged side by side in the second direction, and the assembly transfer vehicle 300 is arranged at one end of the storage section 100 and the pouring section 200 in the first direction. At this time, the assembly transfer vehicle 300 further includes a translation drive member, which can be in the form of a ground rail wheel, or in the form of an electric cylinder or a module. The receiving platform 310 can move in the second direction under the drive of the translation drive member, so as to dock with the storage section 100 or the pouring section 200 as needed.

Specifically, when there is no need to raise the sand mold 1, the assembly transfer vehicle 300 is docked with the storage section 100. After the receiving platform 310 receives the required sand mold 1, the assembly transfer vehicle 300 is translated to the docking pouring section 200, and the receiving platform 310 directly inputs the sand mold 1 into the pouring section 200. When it is necessary to raise the sand mold 1, the assembly transfer vehicle 300 is docked with the storage section 100, and the receiving platform 310 first receives a sand mold 1, and then the sand mold 1 is raised by using the extraction member 320 and the lifting drive member 330; because the sand mold 1 is raised, the receiving platform 310 is empty and can receive a cushion block 2; after the cushion block 2 is in place, the extraction member 320 and the lifting drive member 330 cooperate to put down the sand mold 1, so that the sand mold 1 falls on the cushion block 2, thereby achieving the raising of the sand mold 1.

In one embodiment, the pouring roller 210 is extended along a first direction and can simultaneously receive multiple groups of sand molds 1; the pouring section 200 also includes a first group of driving mechanisms 240, which are used to drive the gantry 220 to move along the first direction so that the ladle 3 can pour the sand molds 1 on the pouring roller 210 one by one.

1 and 3 , in the illustrated embodiment, the gantry 220 is configured to be door-shaped, including two groups of support columns 223 and two beams 224 erected on the top of the two groups of support columns 223; the first group of driving mechanisms 240 includes: two ground rails, either of which extends along a first direction, and the two ground rails are spaced apart along a second direction; the pouring roller 210 is located between the two ground rails; two groups of running wheels, each group of support columns 223 having a group of running wheels rotatably disposed at the bottom, and each group of running wheels is rollably disposed on the ground rails; a driving motor is connected to at least one group of running wheels; during pouring, the driving motor works, the two groups of running wheels rotate, and the gantry 220 moves along the ground rails in the first direction.

In a specific embodiment, before pouring, the sand molds 1 to be poured are first input into the pouring roller 210 one by one, so that a plurality of sand molds 1 are arranged on the pouring roller 210; when the sand molds 1 are in place, the gantry 220 carrying the ladle 3 fully loaded with the pouring solution is at one end of the pouring roller 210 and docks with the first sand mold 1; after the pouring of the first sand mold 1 is completed, the first group of driving mechanisms 240 works, so that the gantry 220 moves along the first direction with the ladle 3 toward the second sand mold 1, and after the ladle 3 is aligned with the pouring port of the second sand mold 1, the first group of driving mechanisms 240 stops working to ensure that the ladle 3 remains aligned with the pouring port of the second sand mold 1 until the pouring of the second sand mold 1 is completed; after the pouring of the second sand mold 1 is completed, the first group of driving mechanisms 240 works again, so that the gantry 220 moves along the first direction with the ladle 3 toward the third sand mold 1... and so on, the ladle 3 pours the sand molds 1 one by one.

At this time, the sand mold 1 that has been poured first can stay on the pouring roller 210 and stand still, so as to facilitate the molding of the pouring solution in the sand mold 1. After all the sand molds 1 are poured, the first sand mold 1 that has been poured is output from the pouring roller 210 first, and then the second sand mold 1 that has been poured is output from the pouring roller 210... and so on, ensuring that each sand mold 1 that has been poured can stay on the pouring roller 210 and stand still for a certain period of time.

Optionally, the pouring section 200 includes two pouring rollers 210 , either pouring roller 210 is extended along a first direction, and the two pouring rollers 210 are arranged side by side along a second direction, and the first direction is perpendicular to the second direction.

1 and 3 , in the illustrated embodiment, the pouring section 200 includes two pouring rollers 210, and any one of the pouring rollers 210 can receive a row of sand molds 1. After the first pouring roller 210 receives a row of sand molds 1, the gantry 220 carries the pouring ladle 3 and moves along the first direction under the drive of the first group of driving mechanisms 240, completing the pouring of each pouring ladle 3 on the first pouring roller 210 one by one. At the same time, the newly prepared sand mold 1 to be poured is input into the second pouring roller 210.
