Description

Technical Field

[0001] The utility model belongs to the field of lathe processing components, in particular to a punching die processing fixture. Background Art

[0002] There are many types of punching equipment, the most common ones are manual punching machines, hand-powered drills, horizontal punching machines, CNC punching machines, EDM perforating, etching punching, etc. Punching dies are equipment used to make fixed holes. The advantage of punching dies is that they can quickly and accurately manufacture a large number of porous parts. The structures of punching dies and continuous dies are basically the same, except that the tooling parts and stamping methods are different. The punching die is a single-process die, and its feeding method is completely different from the automatic feeding method of the continuous die; its positioning method is also different from the positioning method of the continuous die. The functions of the upper die seat and the upper pad in the punching die are the same as those in the compound die. When the punching die is used to process structures such as pipe fittings and steel plates, the core is usually fixedly connected through an iron rod extending from the other end of the machine because the processed pipe fittings or steel plates are relatively long, thereby achieving core fixation;

[0003] For punching of long workpieces, workers need to hold on both sides of the pipe or steel plate with their hands. During the punching process, certain stress will be generated. If the workers’ hands are not stable, it is easy to cause the next punching to shift, and the hole position cannot be aligned, affecting the next step of processing.

[0004] In summary, the utility model provides a punching die processing fixture to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a punching die processing fixture to solve the problem in the prior art that the next punching is easily shifted, and the hole position cannot be aligned, affecting the next processing step.

[0006] A punching die processing fixture comprises a fixture seat, and a plurality of locking parts are installed on the fixture seat, and the locking parts include a limiting slide, a slide slide and a positioning pull piece. The limiting slide is installed on the surface of the fixture seat, and two slide slides are slidably arranged on each of the limiting slides. A transfer block is installed on one side of the slide slide, and telescopic rods are rotatably connected to the transfer block respectively. One end of the two telescopic rods away from the transfer block is rotatably connected to the positioning pull piece, and the positioning pull pieces are fixedly connected by a linkage pull rod, and a clamping piece is rotatably connected to the slide slide. A hydraulic rod is installed on the surface of the fixture seat, and the piston rod on the hydraulic rod is fixedly connected to one of the positioning pull pieces.

[0007] Furthermore, a through slot is provided in the middle of the limiting slide bar, and the linkage pull rod movably passes through the through slot and is connected end to end to the two positioning pull pieces.

[0008] Furthermore, the positioning pull piece is a "U"-shaped structure, and one end of the telescopic rod is rotatably connected to the inner walls on both sides of the positioning pull piece near the opening.

[0009] Furthermore, a rotating shaft is fixedly connected to the bottom of the clamping member, and the rotating shaft is rotatably connected to the surface of the slide bar slide, and an arc-shaped locking groove and a rectangular locking groove are respectively formed at both ends of the clamping member.

[0010] Furthermore, the two telescopic rods are symmetrically arranged along the linkage pull rod and present an "eight"-shaped structure.

[0011] Furthermore, the fixture seat is provided with an installation slot, and two slot sliders are slidably connected in the installation slot, respectively. The slot sliders pass through both ends of the installation slot, and the bottom of the slot slider is fixedly connected with an installation clamp.

[0012] Furthermore, the mounting fixture is a "C"-shaped structure, a threaded rotating rod is vertically arranged at the bottom of the mounting fixture, and one end of the threaded rotating rod is threadedly penetrated through the bottom of the mounting fixture.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can fix different parts of a long workpiece by setting multiple sets of locking parts. When punching, it can eliminate the stress caused by the punching process, reduce the possibility of workpiece displacement, and make the hole position of the processed workpiece more accurate.

[0015] 2. The utility model can simultaneously stretch the positions of multiple telescopic rods through a linkage pull rod, and can adjust the locking or releasing state of multiple locking parts at the same frequency. During the punching process, the position of the workpiece can be quickly changed to fix the punching position of the workpiece.

[0016] 3. The utility model is designed with a rotatable clamping piece with different shapes on both sides, which can adapt to the processing of tubular workpieces and plate-shaped workpieces. Different clamping slots are changed according to the different shapes of the workpieces to be processed, so the adaptation range is wider and the adaptability is higher.
