Description

Cutting device is used in bus duct casing processing

Technical Field

The invention relates to the technical field of cutting equipment, in particular to a cutting device for machining a bus duct shell.

Background

The bus duct shell is generally of a long U-shaped structure, and a plurality of radiating fins extending along the length direction of the bus duct shell are uniformly distributed in the middle of the U-shaped structure. The bus duct shell is taken as an important component of the electric energy transmission equipment, and the processing process of the bus duct shell generally comprises the key links of forming, cutting and the like of a metal plate.

In the processing flow of the bus duct shell, the cutting device is key equipment for realizing accurate segmentation of the shell in the length or width direction. Such devices generally include a table, a clamping mechanism for positioning and clamping the housing, a cutting mechanism for cutting the housing, a driving member, and the like, and after the housing is fixed by the clamping mechanism, a cutting operation is performed by the cutting mechanism to complete the sectional processing of the housing.

During cutting, the contact area of the saw blade with the busway housing can generate a significant amount of metal chips (including chip, powder chips, and coil-like scraps). Under the double influences of the cutting impact force and the gravity of the cutting tool, more scraps can be accumulated in the area closest to the cutting section, and only a small amount of scraps are scattered in the area far away from the section.

In the sweeps cleaning link, the prior art generally adopts the continuous air current along casing length direction to sweep, pushes the sweeps to the cutting section direction of casing. However, in actual operation, as the pushing process continues, scraps near the cross section are continuously gathered in front of the airflow, so that a more densely packed state is formed, and the scraps are further embedded into the fin gaps. Because the strength of the sweeping air flow is fixed, effective impact force is difficult to be formed on scraps clamped in the gaps of the fins, so that the residues cannot be thoroughly blown out, and the cleaning effect is not ideal. Therefore, we propose a cutting device for bus duct shell processing to well solve the above-mentioned drawbacks.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 8, a cutting device for machining a bus duct case includes a table 1 extending in a horizontal direction. The workbench 1 is provided with a main controller, and a PLC programmable logic control system is adopted as a core control unit to control each executing mechanism in the device.

The embodiment also comprises a supporting frame 2, a cutting mechanism 3, two sliding seats 4, two rotating seats 6 and two air blowing pipes 9, and is used for solving the problems that scraps continuously gather near a cutting section and are embedded into fin gaps in the prior art.

Wherein the support frame 2 is fixed on top of the table 1 to provide support for other components in the device. The cutting mechanism 3 is arranged on the support frame 2 and is suspended above the middle part of the workbench 1, the cutting mechanism 3 is electrically connected with the main controller, and the cutting mechanism 3 is controlled by the main controller. Specifically, the cutting mechanism 3 comprises an electric telescopic rod 301 arranged on the top of the supporting frame 2, a cutting machine 302 suspended above the middle part of the workbench 1 is connected to the execution end of the electric telescopic rod 301, and the electric telescopic rod 301 and the cutting machine 302 are respectively in communication connection with a main controller. When the bus duct shell cutting device works, the main controller sends a displacement instruction to the electric telescopic rod 301 according to preset cutting parameters, the cutting machine 302 is driven to move downwards along the Z-axis direction, and the bus duct shell is cut in cooperation with the cutting machine 302.

Secondly, two sliding seats 4 are symmetrically distributed on two sides of the middle part of the workbench 1, the two sliding seats 4 can be mutually close to or far away from each other along the length direction of the workbench 1, and the top of each sliding seat 4 is rotationally connected with a rotating shaft 5. In this embodiment, the top of the workbench 1 is provided with linear modules 12 corresponding to the sliding seats 4 one by one, each sliding seat 4 is fixed at the execution end of the corresponding linear module 12, and each linear module 12 is connected with the main controller in a communication manner, so that the two sliding seats 4 can be driven to approach or separate from each other.

In addition, two rotating bases 6 are in one-to-one correspondence with two rotating shafts 5, and each rotating base 6 is fixed on the top of the corresponding rotating shaft 5. A clamp 7 for clamping the bus duct shell is arranged at the top of each sliding seat 4. Each slide seat 4 is provided with a rotation driving mechanism 8 for rotating the rotary seat 6 along the rotation shaft 5 so that the bus duct case is parallel to the longitudinal direction of the table 1 or perpendicular to the longitudinal direction of the table 1.

Two air blowing pipes 9 are respectively fixed to both sides of the support frame 2 and extend in the width direction of the table 1. A plurality of lateral nozzles 10 are uniformly distributed on the side wall of each air blowing pipe 9 along the axial direction, and an axial nozzle 11 is arranged at one end part of each air blowing pipe 9.

Before cutting, the bus duct shell is positioned and clamped by the clamp 7, the length direction of the bus duct shell is parallel to the length direction of the workbench 1, and the bus duct shell can be cut by the cutting mechanism 3.

After cutting, the two bus duct shells do mutual deviating movement, when the length direction of the bus duct shells is kept parallel to the length direction of the workbench 1, each lateral nozzle 10 works to jet air to the surface of the bus duct shells, so that scraps on the surface of the bus duct shells can be pushed to move towards the cutting surface along the length direction in a concentrated manner, and the scraps can be collected at the cutting surface in a concentrated manner. When the length direction of the bus duct shell is vertical to the length direction of the workbench 1, the axial nozzle 11 works to jet air to the surface of the bus duct shell, point-by-point jetting of fin gaps is realized by matching with movement of the bus duct shell, local high pressure is formed in the gaps by air flow, effective impact force is formed on fine scraps clamped in the gaps, and the clearance rate of the scraps in the gaps is improved to be more than 99%.

With the above design, at the initial stage of cleaning (the bus duct housing is parallel to the length direction of the table 1), the dispersed air flows of the plurality of lateral nozzles 10 are suitable for cleaning in a large area, and the ordered migration of the scraps is ensured. In the later cleaning stage (the bus duct shell is perpendicular to the length direction of the workbench 1), the single axial nozzle 11 is switched, the air flow is changed from dispersion to concentration, the outlet flow speed of the axial nozzle 11 is improved by about 60% under the same air source pressure, the pressure is more concentrated, the air flow resistance of fin gaps can be broken through, and the cleaning difficulty of fine gaps is solved.

The rotary mechanism 8 is described below:

The rotation driving mechanism 8 includes a mounting case 801 fixed to the bottom of the slide seat 4, a worm wheel 802 positioned in the mounting case 801 is fixed to the lower end of the rotation shaft 5, a worm 803 engaged with the worm wheel 802 is rotatably connected to the mounting case 801, and the axial direction of the worm 803 is parallel to the width direction of the table 1. When the worm 803 rotates, the worm wheel 802 is driven to synchronously rotate through tooth surface engagement, so as to drive the rotating seat 6 to rotate along with the rotating shaft 5.

The worm 803 has both ends extending out of the mounting case 801, gears 804 are fixed to both ends of the worm 803, and racks 805 corresponding to the gears 804 are fixed to the top of the table 1. When the gear 804 is meshed with the rack 805, the worm 803 is driven to rotate.

With the design, after the cutting is completed, the main controller instructs the linear module 12 to drive the sliding seat 4 to move away from the workbench 1 along the length direction, the gear 804 and the rack 805 are in a separated state in the initial stage of movement, and the bus duct housing maintains a posture parallel to the length direction of the workbench 1. In the latter stage of movement, the gear 804 is gradually meshed with the rack 805, so as to drive the worm 803 to synchronously rotate, the worm 803 drives the worm wheel 802 and the rotating shaft 5 to rotate through tooth surface meshing, and finally the rotating seat 6 and the clamped bus duct shell are driven to gradually rotate.

When the sliding seat 4 moves to the preset position, the bus duct shell just completes 90-degree rotation, and the length direction of the bus duct shell is converted into a vertical state from being parallel to the workbench 1. During this process, the reverse self-locking nature of the worm wheel 802 and worm 803 creates a reliable mechanical lock, and the swivel seat 6 remains in a stable position even under the influence of radial external forces or equipment vibrations.

The design does not need to additionally arrange a rotary driving motor, and the rotary motion is realized by the moving power of the sliding seat 4. Meanwhile, the meshing characteristic of the worm wheel 802 and the worm 803 has a self-locking function, and can form a reliable locking after the rotating seat 6 is in an initial position or rotates in place, so that the rotating seat 6 is prevented from rotating accidentally due to external force or vibration, and the bus duct shell is ensured to always maintain a stable posture in the cutting or cleaning process.

It should be noted that an inner tube is fixed in the inner portion of the air blowing tube 9 along the axial direction, an annular gap is reserved between the inner tube and the air blowing tube 9, the lateral nozzle 10 is communicated with the annular gap, and the axial nozzle 11 is communicated with the inner tube. The nested structure enables the lateral airflow and the axial airflow to form independent passages, avoids mutual interference, and ensures the stability of two purging modes.

Specifically, a first air inlet pipe 13 communicated with the annular gap is fixed on the air blowing pipe 9, and a first electromagnetic valve 14 is arranged on the first air inlet pipe 13 and can control the on-off of air flow of the lateral nozzle 10. A second air inlet pipe 15 communicated with the inner pipe is fixed on the air blowing pipe 9, and the second air inlet pipe 15 and the first air inlet pipe 13 are connected with an external air source through pipelines. A second electromagnetic valve 16 is mounted on the second intake pipe 15 and is responsible for switching the air flow to the axial nozzle 11. The first solenoid valve 14 and the second solenoid valve 16 are each communicatively coupled to a master controller.

By adopting the design, the main controller controls the first electromagnetic valve 14 and the second electromagnetic valve 16 to realize automatic switching of the lateral nozzle 10 and the axial nozzle 11. Specifically, when the plurality of lateral nozzles 10 are operated, a large purge range can be formed, and scraps on the surface of the bus duct case can be collected in the direction of the cut surface in cooperation with the movement of the slide seat 4.

When switching to the axial nozzles 11, the master closes the first solenoid valve 14 and opens the second solenoid valve 16, the total flow of the external air source being concentrated through the inner tube to the single axial nozzle 11. The outlet pressure is increased by 40% -60% due to the convergence of the air flow, so that high-strength air flow is formed. Aiming at fin gaps of the bus duct shell, high-speed air flow can break through air resistance to form instant impact force, and stubborn scraps such as slag, burrs and the like clamped in the gaps are thoroughly stripped (the clearance rate is improved to 99%), so that the problem that the lateral nozzle 10 is difficult to touch deep gaps due to scattered air flow is solved.

The purging mode switched according to the requirement not only realizes large-area rapid slag removal through the lateral nozzle 10 and shortens the time consumption of single cleaning, but also strengthens the cleaning capacity through the concentrated air flow of the axial nozzle 11, thereby meeting the total flow requirement of the bus duct shell from coarse cleaning to fine cleaning.

In another embodiment of the present application, the sliding seat 4 is penetrated with an arc-shaped abdication hole 17, and a touch plate 18 extending into the arc-shaped abdication hole 17 is fixed at the bottom of the rotating seat 6. When the rotating seat 6 rotates around the rotating shaft 5, the touch plate 18 moves along the arc-shaped abdicating hole 17 in a synchronous track, so that the double functions of mechanical limiting and signal triggering are formed.

A first pressure sensor 19 is arranged at one end of the arc-shaped abdication hole 17, a second pressure sensor 20 is arranged at the other end of the arc-shaped abdication hole 17, and the first pressure sensor 19 and the second pressure sensor 20 are respectively in communication connection with a main controller.

With the above design, when the bus duct housing is in the initial non-rotating state, the touch plate 18 is in stable contact with the first pressure sensor 19, the sensor transmits a continuous pressure signal to the master controller, and the master controller instructs the first electromagnetic valve 14 to open, so that the lateral nozzle 10 is quickly brought into the working state, and the large-scale purging of the surface of the bus duct housing is realized.

When the rotating seat 6 starts to rotate, the touch plate 18 is separated from the first pressure sensor 19, the sensor pressure signal disappears, the main controller cuts off the power supply of the first electromagnetic valve 14, the lateral nozzle 10 stops spraying air immediately, and waste scraps caused by the disturbance of the air flow direction in the rotating process are effectively prevented from splashing.

When the rotating seat 6 completes 90-degree rotation and is in place, the touch plate 18 presses the second pressure sensor 20, a sensor trigger signal is transmitted to the main controller, the second electromagnetic valve 16 is opened, and the axial nozzle 11 is ensured to be restarted after the posture of the bus duct shell is stable, so that concentrated airflow impact is formed. According to the design, through direct correlation between the rotation action and the sensing signal, full-automatic switching of the purging mode is realized, accurate starting of the lateral/axial nozzle under the corresponding posture of the bus duct shell is ensured, and the degree of automation of cleaning operation is greatly improved.

Further, the outlet of the lateral nozzle 10 is fan-shaped flat, and the lateral nozzle 10 is inclined toward the middle of the table 1. The structure ensures that compressed air forms wide and flat air flow after being sprayed out, and can accurately cover the surface of the bus duct shell in cooperation with inclined arrangement. Meanwhile, the fan-shaped air flow keeps uniform pressure distribution in the diffusion process, and flaky and granular waste scraps scattered on the surface of the bus duct shell can be intensively pushed towards the direction of the cutting surface.

The outlet of the axial nozzle 11 is tapered, and the axial nozzle 11 is inclined toward the side of the table 1. The conical shrinkage structure enables the air flow to form an energy gathering effect before being sprayed out, the outlet air flow speed is increased by 60% compared with that of the lateral nozzle 10, the air flow is enough to penetrate through fin gaps of the bus duct shell, and an effective impact force is formed on fine scraps clamped in the gaps. The high-pressure air flow can be guided to push cleaned scraps to the direction of the scraps collecting groove at the edge of the workbench by matching with the inclined arrangement.
