Description

Technical Field

[0001] The utility model relates to the technical field of stamping mechanical devices, in particular to a stamping piece pushing mechanism used in stamping work. Background Art

[0002] A stamping machine is a mechanical device that performs stamping work. It relies on the press and the die to apply external force to the plate, causing plastic deformation or separation, so that the plate becomes a workpiece with a certain shape and size. Sheet material, die and equipment are the three elements of stamping processing. At present, stamping machines have been widely used in the processing and manufacturing industry and are indispensable working machines for industrial production.

[0003] When a stamping machine is working, a supporting pushing mechanism is usually required to push the stamped parts to a suitable processing position for easy stamping. However, when the existing stamping pushing mechanism is in use, the stamping parts cannot be fixed on the pushing platform, resulting in the relatively poor stability of the stamping parts during the pushing process, and they are prone to sliding, so that the position of the stamping work surface is not accurate, which further reduces the stamping accuracy and affects the qualified rate of the workpiece products. Utility Model Content

[0020] Through the above technical solution, the baffle can prevent the punching parts on the punching table from sliding back and forth, and when installing and disassembling the punching table and the U-shaped table, it is convenient to lift them by grasping the two handles.

[0021] Preferably, a plurality of fixing ears are symmetrically fixedly mounted on the front and rear ends of the base, and each of the fixing ears is provided with a mounting hole.

[0022] Through the above technical solution, the fixing ears and the mounting holes facilitate the base to be fixedly mounted on the lower table of the punching machine.

[0023] Compared with the prior art, the utility model provides a punching piece pushing mechanism for punching work, which has the following beneficial effects:
