Technical Field

The invention relates to the technical field of stamping equipment, in particular to a rotary stamping device.

Background

In the stamping process of manufacturing sheet metal parts, various dies are generally used to cut metal blanks. The cutting dies are used primarily for producing a metal blank from a starting material sheet and for forming a stamped part of the final desired shape in a subsequent stamping operation. The stamped parts are typically stacked for storage after the stamping operation.

In daily production, when the stamping parts are stacked and stored, a plurality of same stamping parts can be attached very tightly after being stacked together, are not easy to separate, and bring great difficulty for taking out the parts later. In order to solve such problems, the press parts are designed to be specially processed, for example: on the premise of not influencing the final use of the stamping part, different profiles are formed in several local areas of the stamping part produced successively. It is common to press several dimples at different locations on the punch members, with the dimples between adjacent punch members being located differently so as to increase the clearance between the punch members for material removal during storage. In order to realize the difference of the positions of the dimples between the punching parts, the existing punching die generally adopts a driving device to drive a ratchet wheel to rotate so as to realize the displacement of the dimples. Although the displacement of the dimple can be realized, the whole cost of the stamping die is higher due to the fact that an additional driving mechanism is needed for driving.
