[0002] As we all know, a stamping die is a device used in the production and processing of automotive parts to stamp raw materials, one or more times, and has been widely used in the field of stamping die technology. When stamping larger plates, stamping dies generally place plates of a certain size in the concave die cavity of the lower die, and then use the stamping die to perform processing operations such as punching, bending and cutting on the plates.

[0003] Prior art CN 219004342 U discloses an automatic feeding device for automobile stamping parts, which includes components such as a processing table, a protective box, a storage barrel, and a fixed plate. Although the utility model can feed the raw material workpiece automatically, the positioning effect of the utility model during the feeding process is general. After stopping the pushing of the raw material, the raw material may continue to move forward under the action of inertia, resulting in inaccurate feeding of the raw material, which in turn affects the overall stamping accuracy, and has a certain impact on the stamping yield and stamping quality. Therefore, there is still room for improvement. Utility Model Content
