Description

Technical Field

[0001] The utility model relates to the technical field of chain production punching devices, in particular to a chain production metal parts punching device. Background Art

[0002] Chain punching machine is a commonly used stamping equipment, mainly used for stamping processing of metal materials. Its working principle is: the upper die and the lower die are assembled to the corresponding positions of the punching machine, the metal material is fed into the stamping area through the feeding device, and the drive system causes the upper die to start moving downward, exerting impact force on the metal material. The working panel of the upper die fits tightly with the bottom plate of the lower die, clamping the metal material between the two, and pressing it into the shape of the workpiece according to the required shape. After the stamping is completed, the upper die starts to lift up, so that the bottom plate of the lower die is separated from the workpiece and the workpiece is taken out. After the entire stamping process is completed, the drive system will restart and restore the upper die to its initial position, preparing for the next stamping cycle.

[0003] During the stamping process of the above-mentioned chain production, the operation of the drive system will generate a large impact force on the lower die. The existing stamping device does not have a corresponding buffer mechanism for the lower die. When the impact force generated by the drive system is too large, the lower die may be deformed or deformed unevenly, which will cause the stamped workpiece to be inaccurate in size and irregular in shape, affecting product quality and consistency.
