Abstract

The invention provides a flanging and punching die. The flanging and punching die comprises an upper die base and a lower die base, wherein the upper die base is connected with an upper die pressing core, the lower die base is connected with a lower die pressing core, the upper die base is connected with an upper die lateral punching driving block, the upper die lateral punching driving block is provided with a lateral punching wedge forced rollback hook, the lower die pressing core is respectively connected with an upper flanging cutter block, a lower die lateral punching female die insert, a lateral punching wedge and a lateral punching wedge guide pillar, the lateral punching wedge and the lateral punching wedge guide pillar is a moving pair, the lateral punching wedge is provided with a lateral punching wedge forced rollback groove, the lateral punching wedge forced rollback hook is arranged in the lateral punching wedge forced rollback groove, the lateral punching wedge is connected with a lower die lateral punching male die insert, and the lower die lateral punching male die insert and the lower die lateral punching female die insert are matched with each other. The flanging and punching die has the advantages of achieving the purpose of simultaneously flanging and punching, and reducing work procedures.

Description

technical field [0001] The invention relates to a mold, in particular to a flanging punching mold. Background technique [0002] On large body panels such as Body Side Inner and Tail Gate Inner, there are often upward flanging, downward flanging and side openings at the same time due to the needs of the body structure function . The traditional mold structure cannot realize the side punching at the same time as the upper flanging, which needs to be distributed in different processes, and often requires additional processes because of the side punching. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a flanging and punching die which can carry out flanging and punching simultaneously. [0004] The invention provides a flanging punching die, comprising an upper mold base and a lower mold base, the upper mold base is connected with an upper mold pressing material core, the lower mold base is connected with a lower m...
