Abstract
The utility model discloses a composite die for punching and straightening connecting rods, which comprises an upper die holder fixing plate, an upper die holder, an upper die supporting plate, a large-end punch die holder, a large-end punch, a small-end punch die holder, a small-end punch, an upper straightening die fixing plate, an upper straightening die, a lower die holder and a lower straightening die mounted on the lower die holder. A nitrogen spring is mounted between the upper straightening die fixing plate and the upper die holder fixing plate, an auxiliary stripper rod is further mounted above the upper straightening die fixing plate, the large-end punch die holder, the small-end punch die holder and the nitrogen spring are fixed to the upper die holder fixing plate through screws, the large-end punch is fixed to the lower side of the small-end punch die holder through a screw, and the small-end punch is fixed to the small-end punch die holder through a screw. By the aid of the composite die, operation originally completed by two persons at two working steps is completed by one person at one working step, production efficiency is improved, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of connecting rod punching and proofreaies and correct composite die.
Background technology
In the prior art; The punching of connecting rod is normally accomplished through two equipment, two molds with proofreading and correct, and this has increased production cost greatly, and in punching and this two work step of correction; Owing to there is not pretightning force, cause that link lever deflection is big, symmetry is poor, big end endoporus allowance is many.
Therefore, be necessary to provide a kind of connecting rod punching that solves the problems of the technologies described above to proofread and correct composite die.
The utility model content
The utility model technical problem to be solved is: composite die is proofreaied and correct in the punching that provides a kind of and enhance productivity, reduce production costs.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: composite die is proofreaied and correct in a kind of connecting rod punching; It comprises: upper bolster fixed head, upper bolster, patrix supporting plate, major part drift die holder, major part drift, microcephaly's drift die holder, microcephaly's drift, proofread and correct upper mould fixed plate, proofread and correct the upper die and lower die seat and be installed on the correction counterdie on the die shoe; Between said correction upper mould fixed plate and the upper bolster fixed head nitrogen spring is installed; The top of said correction upper mould fixed plate also is equipped with auxiliary material discharging rod; Said major part drift die holder, microcephaly's drift die holder and nitrogen spring be all through screw and upper bolster fixed head fixing mutually, and said major part drift is immobilizated in the below of major part drift die holder through screw, and said microcephaly's drift is immobilizated in the below of microcephaly's drift die holder through screw.
The beneficial effect of the utility model is: through using this kind composite die, the work that originally needed two work steps, accomplish with two people become with a people, a work step accomplish, improved production efficiency, reduced production cost.
Description of drawings
Fig. 1 proofreaies and correct the structural representation of composite die for the connecting rod punching.
Among Fig. 1: 1, upper bolster fixed head, 2, upper bolster, 3, the patrix supporting plate, 4, major part drift die holder; 5, major part drift, 6, microcephaly's drift die holder, 7, microcephaly's drift; 8, proofread and correct upper mould fixed plate, 9, proofread and correct patrix, 10, die shoe; 11, proofread and correct counterdie, 12, nitrogen spring, 13, auxiliary material discharging rod.
The specific embodiment
See also Fig. 1; Composite die is proofreaied and correct in a kind of connecting rod punching; It comprises: upper bolster fixed head 1, upper bolster 2, patrix supporting plate 3, major part drift die holder 4, major part drift 5, microcephaly's drift die holder 6, microcephaly's drift 7, proofread and correct upper mould fixed plate 8, proofread and correct patrix 9, die shoe 10 and be installed on the correction counterdie 11 on the die shoe; Between said correction upper mould fixed plate 8 and the upper bolster fixed head 1 nitrogen spring 12 is installed; The top of said correction upper mould fixed plate 8 also is equipped with auxiliary material discharging rod 13, and said auxiliary material discharging rod 13 can be assisted and taken off material, and said major part drift die holder 4, microcephaly's drift die holder 6 and nitrogen spring 12 are all through screw and upper bolster fixed head 1 fixing mutually; Said major part drift 5 is immobilizated in the below of major part drift die holder 4 through screw, and said microcephaly's drift 7 is immobilizated in the below of microcephaly's drift die holder 6 through screw.
Said connecting rod punching is proofreaied and correct composite die and is installed on the punch press; Before drift contact big end endoporus gross weight; Nitrogen spring 12 has the decrement of 5mm, thereby gives pretightning force of workpiece through proofreading and correct patrix 9, and punch press continues to move downward 40mm; Nitrogen spring 12 continues compression 40mm simultaneously, and punching is accomplished.Then punch press continues to move downward 0.2-0.8mm (this moment, nitrogen spring did not compress), accomplishes correction through proofreading and correct patrix 9 with correction counterdie 11.The punch press backhaul, nitrogen spring elongation, workpiece break away from from drift and correction patrix 9, accomplish a circulation.
Through using this kind composite die, the work that originally needed two work steps, accomplish with two people become with a people, a work step accomplish, improved production efficiency, reduced production cost.
