Abstract

The invention relates to a trimming-turning knife block, a trimming-turning mould and a mould assembly. The trimming-turning knife block (1) comprises a straight upper trimming cutting edge (11) and an upper turning cutting edge (12), and further comprises a transition part (13) connected between the upper trimming cutting edge (11) and the upper turning cutting edge (12), so that the highest point of the upper turning cutting edge (12) is lower than the upper trimming cutting edge (11). With the adoption of the technical scheme, the trimming-turning knife block provided by the invention can prevent splitting fragment generating.

Description

technical field [0001] The present disclosure relates to the stamping field, and in particular, relates to a trimming tool block, a trimming die and a die assembly. Background technique [0002] In the production of models with sunroofs on the roof, stamping process is usually used to process the entire plate to realize the opening of the sunroof. [0003] In the prior art, a trimming mold is usually used to perform trimming and flanging treatment on the sheet material. Since trimming and flanging are carried out at the same time, the amount of intake at the edge of the trimming knife block is not uniform. Therefore, when the waste is not completely separated, it is easy to cause tearing between the workpiece part and the waste part of the plate. These tear debris are easily adsorbed on the mold and / or product, and as the workpiece part enters the stamping process, these tear debris are brought to the stamping die. If these torn debris are not cleaned up in time, it will s...
