Abstract

The utility model provides a polyamine piercing die, which consists of an upper die assembly and a lower die. The lower die is arranged under the upper die assembly, the upper die assembly comprises a beating head, a polyamine spring, a base plate, clamping sleeve, an upper die core, an upper die handle, a guide sleeve, a match grinding spacer and a pressing sleeve, the beating head is in threaded connection with the upper die handle, the upper die core is arranged at the lower end of the upper die handle, the upper die handle and the upper die core are integrally clamped by the clamping sleeve, the match grinding spacer for eliminating clearances is arranged between the upper die handle and the upper die core, the lower end of the upper die core and the pressing sleeve are fittingly mounted so as to realize guiding, the guide sleeve is sleeved on the periphery of the clamping sleeve, the base plate is disposed at the upper end of the guide sleeve, and the polyamine spring is installed between the base plate and the beating head. The polyamine piercing die adopts the polyamine piercing spring to replace a traditional die spring, has compact structure and is simple and practical.

Description

Polyamine fat punching die
Technical field
The utility model relates to a kind of processed mould that is used for, and is specifically related to a kind of polyamine fat punching die.
Background technology
Punching die is mainly used in the bus processing machine, and this mould can carry out actions such as punching, impression, step are dashed, corner cut, side cut, cut-out, chamfering to copper bar.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of polyamine fat punching die to be provided.
The technical solution adopted in the utility model is: a kind of polyamine fat punching die, form by last mould assembly and counterdie, described counterdie be arranged on mould assembly under, the described mould assembly of going up comprises attacking head, polyamine fat spring, backing plate, gripping sleeve, upper mold core, last die shank, guide pin bushing, match grinding spacer ring and binder cover, between described attacking head and the last die shank by being threaded, the lower end of last die shank is provided with upper mold core, last die shank and upper mold core become one by described gripping sleeve chucking, be provided with the match grinding spacer ring of eliminating the gap effect between last die shank and the upper mold core, the lower end of upper mold core cooperates guiding with the binder cover, described guide pin bushing is sleeved on the periphery of gripping sleeve, the upper end of guide pin bushing is provided with backing plate, and polyamine fat spring is housed between backing plate and the attacking head.
By being threaded, regulating the upper-lower position of attacking head and can control the whole height of going up mould assembly between described attacking head and the last die shank.Gripping sleeve is one with upper mold core and last die shank chucking, and the height of match grinding spacer ring guarantees to be in place between upper mold core and the last die shank, and is very close to each other.Guide pin bushing plays the mould guiding and supports whole effect of going up mould assembly.Binder is enclosed within when processing copper bar and counterdie compresses copper bar together, guarantees crudy and precision.
Operation principle: when copper bar was carried out the punching press action, copper bar was at first by the position of feeding to counterdie.Bus processing machine oil cylinder is descending, and drift hits attacking head, and the whole mould assembly of going up moves downward.When the binder cover is pressed onto the copper bar upper surface, under the effect of hitting external force, polyamine fat compression deformation of the spring, upper mold core moves downward carries out copper bar punching action.After finishing a punching action, oil cylinder is up, and polyamine fat spring rebounds under the spring force effect, makes upper mold core and last die shank return to initial position.The utility model is used polyamine fat spring and is replaced traditional mould compression spring.
Beneficial effect: the utility model adopts polyamine fat spring to replace traditional die springs, and compact conformation is simple and practical.The first, simple in structure, long service life is low to working condition requirement.The second, mold weight greatly alleviates, the replacing of mould when being convenient to operate.The 3rd, cost reduces, and compares with same specification rectangular mould spring or dish-shape die spring, and cost reduces by 40%.
