Beyond trimming die structure, including trimming die set and alloy mould, upper die sets with internal cutting edges with a hole at the centre of the blanking die, the alloy under the end of the product division alloy blocks, are embedded in the middle of the alloy mould and alloy blocks position has rejected material, the product of the alloy with block header with convex cutting edges, trimming convex platform of the diameter of the internal hole diameter is less than cutting die.After the above structure is adopted in the processing of nut punching rod, the edge can be removed at one time in the cutting process without the phenomenon of pulling and tearing, so the product will not be pulled and bent, and the incision will have no burr, which improves the qualified rate of the product and the quality of the product, and reduces the cost of the product.

The edge-cutting die structure of the blade can solve the phenomenon of edge-cutting due to the deviation of the blade body during edge-cutting of the existing edge-cutting die, so as to ensure the finished product processing after forging and reduce the production cost.The utility model includes a trimming die, which is characterized by: a retaining block is arranged on the trimming die and the outer end of the shaping cavity of the forging member. When trimming, the forging member rests on the retaining block.

The installation structure of the edge cutting die and the nut punching rod accessories can solve the problem of low installation efficiency caused by the upper die seat needs to be turned twice when the existing edge cutting die is installed.The invention also provides an installation method for the edge cutting mould.Including mold base, trimming punch, trimming die and mold base, the upper die between the bridge and the lower die through positioning clamping guide pin, guide sleeve, guide, whose character is: it includes fixed plate and the fixed plate die, punch blanking punch through the punch installed on the fixed plate mold base, the trimming die through the die plate installed on the trimming die, blanking punch and trimming die by clearance fit.
