Description

Mould is cut in automobile chassis trailing arm punching deburring
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of punching deburring for automobile chassis trailing arm and cuts mould.
Background technology
At present automobile chassis trailing arm process in, deburring adopts the processing mode of side deburring, the mould of side deburring rushes the bad control of platform dynamics, processing difficulties, and mould is large, lathe is larger, causes that mould is unstable, edge of a knife easy damaged, once edge of a knife damage, cause the crudy of product to decline, and cutter piece and mould be integral type, maintenance difficult.
Utility model content
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of simple in structure, mould of can be simultaneously the automobile trailing arm product of two one being carried out punching, deburring simultaneously, cut is provided, and adopts square impact deburring, easy to process, and deburring is effective; Cope match-plate pattern integrates trimming and piercing die splitting function, and cutter piece adopts insert structure, and repair and replacement are convenient; And in die operation process, square impact operation makes mold integral stressed evenly, reduces edge of a knife wearing and tearing, extends die life.
The purpose of this utility model is to provide a kind of automobile chassis trailing arm punching deburring and cuts mould, comprise lower bolster, cope match-plate pattern, be positioned at the die on cope match-plate pattern, the left and right sides of described die is provided with the mold insert cutter piece for punching, described cope match-plate pattern is provided with for cutting the drift of cutting of two trailing arm connecting portions, be positioned at the aperture drift of cutting drift both sides, on cope match-plate pattern, be provided with the punch fixing plate for aligning punch, punch fixing plate lower end is provided with holding pad, on punch fixing plate and holding pad, offer the through hole for drift descent path, insert on cutter piece and be provided with the tool bore matching with aperture drift, two ends, holding pad left and right are provided with trimming cutter.
Further improvement of the utility model is: the two ends, left and right of described lower bolster are provided with guide pillar, and the cope match-plate pattern left and right sides is provided with the guide pin bushing matching with guide pillar.
Further improvement of the utility model is: between described holding pad and punch fixing plate, be provided with green spring.
Further improvement of the utility model is: described mold insert cutter piece is detachable.
The beneficial effects of the utility model: the utility model is simple in structure, can the automobile trailing arm product of two one be carried out punching, deburring, be cut simultaneously, adopt square impact deburring, easy to process, and deburring is effective; Cope match-plate pattern integrates trimming and piercing die splitting function, and cutter piece adopts insert structure, and repair and replacement are convenient; And in die operation process, square impact operation makes mold integral stressed evenly, reduces edge of a knife wearing and tearing, extends die life; And two connected automobile trailing arms of one are synchronously carried out punching, deburring, cut operation simultaneously, obtain the product of two moulding, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1-cope match-plate pattern, 2-lower bolster, 3-die, 4-mold insert cutter piece, 5-cuts drift, 6-aperture drift, 7-punch fixing plate, 8-holding pad, 9-trimming cutter, 10-guide pillar, 11-guide pin bushing, the green spring of 12-.
