Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die with a guide structure. Background Art

[0002] A stamping die is a tool used to stamp metal sheets or strips into the desired shape. It is an indispensable part of stamping technology and is widely used in machinery, automobiles, electronics, home appliances, construction, aerospace and other fields. In the manufacturing process, stamping dies play an important role and can effectively improve manufacturing efficiency, reduce costs and improve product quality.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN217858402U discloses a stamping die with a guide structure. The device is provided with a first spring on the outside of the buffer rod, and a guide rod is provided on the basis of the upper die seat. The guide rod can slide in the guide groove, so that when the upper die seat and the lower die seat are combined to stamp the workpiece, they have good guidance and ensure the accuracy of the mold closing. However, in actual use, the device cannot push the workpiece in time after stamping, resulting in a stagnation of the production line. Workers need to intervene manually to solve the pushing problem, which not only increases the labor cost, but also affects the overall production efficiency. In view of this, we propose a stamping die with a guide structure. Utility Model Content
