Description

Technical Field

[0001] The utility model relates to the field of punching machines, in particular to a punching positioning mechanism for automobile parts. Background Art

[0002] Auto parts are various independent parts or components that make up a car. They work together to form a complete automobile system. Some auto parts are made by stamping, so a stamping machine is needed to stamp the steel plate to make it reach the required shape. Therefore, a positioning mechanism is needed on the stamping machine to fix the position of the steel plate. For this purpose, a stamping positioning mechanism for auto parts is proposed.

[0003] Most of the positioning mechanisms of existing punching machines cannot effectively adapt to different sizes of plates. Therefore, when punching plates of different sizes, the staff is required to manually adjust the position of the positioning mechanism so that the positioning mechanism fixes the plate in the punching area. This will relatively increase the work intensity of the staff and reduce the work efficiency to a certain extent. In addition, the existing positioning mechanisms use consistent side clamping when clamping plates of different thicknesses. Therefore, when the plate is thinner, clamping from the side may cause the side of the plate to curl. For this reason, technical improvements are urgently needed. Utility Model Content
