Description

A pipe shaping machine

technical field

The invention relates to a pipe shaping device.

Background technique

At present, the existing pipe fitting shaping equipment generally uses manual grinding or other equipment for partial grinding after forming. Since the pipe fittings used in special equipment have high requirements on length and shape, if a special mold is designed, the cost will be large. It is easy to cause deformation during the material and pressing process, and it is inconvenient to use. In addition, in the current industry, after the pipe fittings are pressed, it is necessary to manually fill in fillers to prevent corrosion or deformation.

Contents of the invention

The object of the present invention is to provide a pipe fitting shaping machine, the push-out mechanism drives the mold to press down the shaping and stripping, realizes automation and is easy to use.

In order to solve the technical problems, the present invention proposes a pipe shaping machine, which includes an upper mold assembly with a template and a pressing die, a lower mold assembly, and a push-out mechanism arranged in the frame. The upper mold assembly can be For moving, a middle connecting plate is arranged between the upper mold assembly and the lower mold assembly, and the middle connecting plate is connected to the lower mold assembly through a guide column, and one end thereof is connected to a rotatable ejection mechanism, and the upper mold assembly and the ejection mechanism The space is connected with the gear assembly through the rack. The push-out mechanism is located under the middle connecting plate. The die on the upper die assembly and the lower die assembly is located at one end of the template. When in use, the push-out mechanism rotates to drive the upper die assembly to press down until The upper die is connected with the lower die, and then, the push-out mechanism pushes out the shaped pipe fittings, which realizes the automation of the shaping process, is easy to use, and is easy to replace the die.

The push-out mechanism includes a cylinder, a motor and a main shaft, wherein the cylinder and the motor are arranged in the installation frame and connected with the main shaft. A one-way clutch is provided, and the surface of the clutch is provided with a spline sleeve, and the pressing of the upper die is realized through the rotation of the main shaft and the rack, which is convenient for control, and the clutch is convenient for controlling the pressing down of the upper die assembly.

The pier round die is set outside the main shaft, and the pier round die is connected to the connecting plate through the guide sleeve at one end. In addition to simply realizing the partial shaping of the pipe fittings by the cooperation of the upper die and the lower die, the pier round die can also realize the pipe fittings The outside is rounded and shaped to remove burrs, etc., to further expand the actual use effect and facilitate operation.

One end of the main shaft is connected to the push rod, and the upper mold assembly is connected to the push rod seat plate. The push rod seat plate is provided with an opening for the push rod to pass through, and the push rod is used to push out the pipe from the die. When separating from the lower mold assembly, put the pipe fittings into the pier round mold and fix it, then start the device, the upper mold presses down, the push rod seat plate, and the pipe fittings should have filling materials, so that they can follow the main shaft to rotate and push out.

A spring is arranged between the bottom of the push-out mechanism and the lower mold assembly, which is convenient for reset after pressing down.

The press dies on the upper die assembly and the lower die assembly are located on one side of the push rod seat plate, which is convenient for setting the pier round die in the middle.

A number of soft collision blocks are set at the bottom of the upper template to prevent damage to the equipment.
