The existing common male die is of an integral structure, please refer to fig. 5, and only needs to be TD again after polishing; but the lifetime after TD is much worse than before. The common forming punch can be TD 3 times at most. The male die needs to be replaced integrally, and the cost of the die is high.

In addition, the damage of the male die can be accelerated by unreasonably arranging the corner radius at the forming groove of the male die according to the shape of the product; experiments are carried out on the basis of the existing male die in the research and development time process, and the experimental contents are as follows: referring to fig. 6 to 9, an arc-shaped guide surface consistent with the shape of the product is arranged at the position of a groove forming punch of a male die, the radius R2 of a transition fillet is 8mm, and the radius R1 of the transition fillet between forming surfaces is 5 mm; when experimental results were obtained, the yield was improved, but it was still low.

Therefore, the utility model relates to an improve mould life, easily change reduces mould use cost's shaping terrace die subassembly.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides an improve mould life, easily change reduces mould use cost's shaping terrace die assembly of shaping terrace die assembly.

The utility model discloses a realize like this, a shaping terrace die subassembly, terrace die body on the fixed mounting die fixing board sets up the terrace die drift that is used for the shaping recess on terrace die body, its characterized in that: the male die punch is embedded on the male die body; the male die body is provided with an embedded groove corresponding to the product groove, and the section of the embedded groove is T-shaped; the punch comprises a punch body, a T-shaped inserting part corresponding to the T-shaped embedding groove is arranged on the rear side surface of the punch body, a through stepped fixing hole is formed in the T-shaped inserting part in the height direction, and a fastening bolt connected with a die fixing plate penetrates through the fixing hole; the front of the T-shaped inserting part is a forming part; the forming part is characterized in that a circular arc guide surface is arranged at the feeding end of the forming part, a plurality of forming surfaces with the shapes consistent with those of product grooves are arranged on the forming part at the lower edge of the circular arc guide surface, circular arc transition is formed between the adjacent forming surfaces, the upper edge of the circular arc guide surface is in a linear structure, and the circular arc radius between the adjacent forming surfaces is larger than that of the circular arc guide surface.

Preferably, in the above technical solution, the radius of the arc transition is R15mm, and the radius of the arc guide surface is R12 mm.

The utility model has the advantages and positive effect: compared with the existing male die, the utility model has the advantages that after the male die punch at the forming groove is worn, other male die bodies can still be continuously processed and used, the disassembly of the male die punch can be realized only by loosening the fastening bolt penetrating into the fixing hole of the T-shaped inserting part on the punch body and being connected with the die fixing plate, and a new male die punch can be reinstalled by cleaning the T-shaped groove after the disassembly, so that the equipment halt time is greatly reduced, and the production efficiency is improved; in addition, the feeding end of the forming part is provided with an arc-shaped guide surface, the upper edge of the arc-shaped guide surface is of a linear structure, and the arc radius between the adjacent forming surfaces is larger than that of the arc-shaped guide surface, so that the mode that the male die just contacts the plate is changed, and the abrasion is reduced; and then improve mould life, easily change reduces mould use cost.
