Die for four-sided side trimming of protruding amount of inner and outer cones of truck

Abstract

The invention discloses a die for four-sided side trimming of the protruding amount of inner and outer cones of a truck. The die comprises an upper die base and a lower die base, wherein a profiling pressing block is fixedly mounted in the middle region of the upper die base; a plurality of pushing structures are vertically arranged on the periphery of the upper die base and used for providing power required for trimming the protruding amount of the inner and outer cones; a mounting plate is arranged on the lower die base, and a die core is mounted in the region matched with the profiling pressing block and in one face, facing the upper die base, of the mounting plate; a plurality of trimming mechanisms are mounted on one side, facing the upper die base, of the mounting plate; the trimmingmechanisms comprise sliding blocks and a plurality of trimming punch assemblies mounted on the sliding blocks; and the sliding blocks are driven by the pushing structures to move to the direction ofthe profiling die core. According to the die, accurate trimming of the edges of the protruding amount of an inner and outer cone assembly can be realized, the multi-directional position limitation ofthe inner and outer cone assembly can be realized, the phenomenon of repair welding or scrapping caused by unstable height of the protruding amount is avoided, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mold processing, in particular to a four-sided side edge trimming mold for the protruding amount of inner and outer cones of trucks. Background technique [0002] With the development of society, major automobile manufacturers have higher and higher requirements for the accuracy of auto parts. The traditional inner and outer cone components mainly consist of an inner cone and an outer cone set on the inner cone. The bottom of the inner and outer cone components is a large Port, the top is a small port; in addition, due to the high flatness of the inner cone in the process of mass production and instability, the protrusion size after spot welding is too high, and the defective rate is about 10%, so it is necessary to involve the inner and outer cone components of the truck If the edge trimming process is processed with a traditional lathe, the production speed is slow and the turning tool is easy to wear, which incr...
