Structure and installation of edge cutting die
Beyond trimming die layout, everything on the trimming die set and alloy mould, product on the edges of the die set with internal intermediate cutting die with a hole, the alloy under the end of the product division alloy blocks are embedded, in alloy mould and the center of the set piece 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 adopting the above layout, in the cutting time may be the edge of a one-time cut removed, will not appear pull pull broken signs, so that the product will not be pulled twists and turns, code words without burr, changsha nut punching bar improved the product pass rate and product quality, reduced the cost of the product.
Blade edge cutting die layout, which can deal with the existing edge cutting die edge because of the blade position deviation caused by the phenomenon of cutting deviation, so as to guarantee the processing of forged products, reduce the production cost.The utility model includes a chamfered die, which is characterized by a chamfered die and a chamfered cavity with a block at the outside end.
The installation layout of the edge cutting mould, shaoxing nut punching rod can deal with the problem of low installation efficiency caused by the requirement of the upper die seat to turn twice during the installation of the existing edge cutting mould;This discovery also provides an installation method for the edge cutting mould.Mold base on its cover, trimming punch die and trimming die and lower die, die on the bridge and the lower die through a process between guide pillar, zhejiang nut bar guide bush guide positioning clamping, its characteristic is that the firm also covers a punch plate and die plate, trimming punch through the process of punch on solid plate installed on the mold base, the trimming die through a process of the die plate installed on the trimming die, blanking punch and trimming die clearance fit through the process.
