Description

A cold stamping device for auto parts

technical field

The invention relates to the field of cold stamping of auto parts, more specifically, to a cold stamping device of auto parts.

Background technique

Some parts in automobiles (such as spring trays, spring seats, spring brackets, end covers, covers, compression valve covers, etc.) in automobile shock absorbers need to be processed by cold stamping, and some cold stamping parts require manual work. To operate loading and unloading, the patent literature with the prior art publication number CN110814140A provides a cold stamping device for auto parts with a self-contained unloading device, which can cooperate with the blocking block on the stamping seat through the use of unloading components. Automatic retrieving, the block is removed and seated on the stamping seat, which saves the time of manually placing the block and helps to improve the efficiency of cold stamping processing; it does not need to operate the operation of repeatedly placing the block manually, which helps to reduce the operator's arm labor intensity.

Although the device has many beneficial effects, it still has the following problems: the device has a low degree of automation, and the stamped parts still need to be taken manually, which is poor in practicability. In view of this, we propose a cold stamping device for auto parts.
