Description

[0001] The invention relates to the technical field of stamping equipment, and in particular to a stamping device for processing automobile stamping parts. Background Art

[0002] As the name implies, automotive stamping parts are metal stamping parts that make up automotive parts. There are many varieties of automotive stamping parts, such as automobile shock absorber stamping parts spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, lug, bracket, etc. are all automotive stamping parts. Among automotive stamping parts, some become automotive parts directly after stamping, while the other parts need to be processed by welding, machining, painting and other processes before they can become automotive parts. Machining includes stamping of stamping parts. The stamping device is used to stamp the stamping parts into a specific required shape.

[0003] At present, when stamping automobile workpieces, stamping devices are mostly loaded and unloaded manually. If the workers do not operate in a standardized manner, accidents are very likely to occur, and the applicability is poor. During processing, some workpieces will fall off some debris. If the debris is not cleaned up in time and remains on the mold, then the next time the workpiece is stamped, it is very likely that some uneven concave and convex surfaces will be left on the workpiece, and qualified stamping parts cannot be obtained. Moreover, during processing, the pressed workpiece has no clamping mechanism and is very likely to skew and jump, which greatly affects the quality of the stamping parts and reduces the production efficiency of the device.
