Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, and in particular to a punching equipment for producing chain links. Background Art

[0002] A chain is a metal link or ring, mainly used for mechanical transmission, traction and obstacle traffic channels. It is composed of rigid components, forming a flexible system, and is one of the basic mechanical parts. Chains are widely used. Chains play a key role in mechanical transmission, and can form a compact whole of various connected parts of a machine, thereby improving mechanical performance.

[0003] The chain mainly includes inner link plates, outer link plates, self-locking pins, pin shafts, rollers and sleeves, among which the inner link plates and outer link plates are collectively called chain links, which need to be punched during production. Currently, the punching of chain links is mostly done by hand-throwing, and then taken out after punching. Since the chain links are small, they are not stable enough when placed on the workbench when punched. At the same time, they are small in size, and are not safe to take and put, which delays time and is not convenient for installation. Summary of the invention
