Abstract
The invention discloses a connecting bar punching and correcting combined die, which comprises an upper die seat fixing plate, an upper die seat, an upper die bolster, a big-head punching head die seat, a big-head punching head, a small-head punching head die seat, a small-head punching head, a correcting upper die fixing plate, a correcting upper die, a lower die seat and a correcting lower die mounted on the lower die seat. Nitrogen gas springs are mounted between the correcting upper die fixing plate and the upper die seat fixing plate; an auxiliary stripping rod is further mounted above the correcting upper die fixing plate; the big-head punching head die seat, the small-head punching head die seat and the nitrogen gas springs are all fixed with the upper die seat fixing plate through screw bolts; the big-head punching head is fixed below the big-head punching head die seat through a screw bolt; and the small-head punching head is fixed below the small-head punching head die seat through a screw bolt. With the adoption of the combined die disclosed by the invention, the work which needs to be finished by two persons in two process steps originally can be finished by one person in one process step, so that the production efficiency is increased, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of connecting rod punching and proofread 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.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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 invention has the beneficial effects as follows: 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.
