Abstract

The invention provides a punch structure and a stamping method, and belongs to the technical field of stamping. The punch structure is used for stamping a plate-shaped piece, the plate-shaped piece isprovided with a first through hole, burrs are generated at the edge of the first through hole located on one side plate face of the plate-shaped piece, the punch structure comprises a second punch head part, the second punch head part is used for stamping and flanging from one side plate face of the plate-shaped piece to the other side plate face of the plate-shaped piece, the edge of the stamping end of the second punch head part is a second fillet transition, and the second fillet transition is used for removing the burrs. According to the punch structure, a mode of removing burrs manuallyis canceled, and the manufacturing process is saved, so that the manufacturing efficiency of flanging is improved.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a punch structure and a stamping method. Background technique [0002] With the continuous advancement of technology, stamping technology has been widely used as the most efficient processing technology in mechanical processing, especially in the production process of home appliances, the shells, skeletons and other mechanisms of home appliances are generally prepared by stamping technology, and home appliances The shell, skeleton and other mechanisms of the product are usually made of plate-shaped parts through multiple stamping processes, and the plate-shaped parts usually need to be stamped out during the stamping process to facilitate the subsequent preparation process. [0003] However, during the stamping process of the flanging of the plate-shaped part, burrs will be generated at the raised edges thereof, and the burrs need to be removed manually, which adds a new manufac...
