Description

Porous series products punching sizing continuous mould

Technical field

The utility model relates to technical field of mold, and specifically, it is a kind of for the continuous mould to the punching of porous series products and shaping.

Background technology

The porous series products is a kind of product that die industry often need to be processed.

Traditional way is the distribution punching, adopts many group moulds to realize the multistep punching, thereby produces qualified product.And hard for some materials, to the product of the required distance more much higher hole class between aperture, limit, Kong Bianyu hole, because the material of product is harder, pitch-row is little, makes the Kong Bianyi upset of product, product flatness after punching is low, and die cost is high, production efficiency is low; Can not satisfy modern society and produce the more and more higher requirement of porous series products punching die.

Therefore, prior art awaits improving and improving.

Summary of the invention

For the deficiencies in the prior art part, the purpose of this utility model is to provide that a kind of die cost is low, production efficiency is high, solves nearly limit, the hole upset that produces of Kong Yukong of the hard material product of processing and the punching sizing continuous mould of flatness problem.

For achieving the above object, the utility model is realized by following technological means: a kind of porous series products punching sizing continuous mould, comprise by upper bolster, the upper backboard that contacts with the upper bolster lower surface, the punching unit and the shaping unit that contact with upper backboard lower surface, by the counterdie that the lower bolster, lower bolster and the die shoe that contact with aspect from top to down form, described punching unit comprises punching upper padding plate, punching train wheel bridge, punching stripper plate and the punching holding pad that contacts with aspect from top to down; Described shaping unit comprises shaping upper padding plate, shaping train wheel bridge, shaping stripper plate and the shaping holding pad that contacts with aspect from top to down; The guide pin bushing that described punching holding pad and shaping holding pad are equipped with guide pin setting corresponding to lower bolster matches; Described punching unit is provided with a plurality of drifts, and on those drifts and counterdie, the through hole of corresponding setting matches; Described shaping unit is provided with a plurality of shaping heads, and on those shaping heads and counterdie, the blind hole of corresponding setting matches.

Further, the epimere of described drift, interlude and hypomere are stepped that diameter diminishes gradually, and rounding off between epimere and interlude, interlude and hypomere, and the bottom end face is the indent arc.

Further, described shaping head epimere, interlude and hypomere be stepped that diameter diminishes gradually, and rounding off between epimere and interlude, interlude and hypomere, the bottom end edge is the cylindrical arc.

Compare with conventional art, the beneficial effects of the utility model are: due to the design of adopting said structure, namely adopt the continuous mould of punching unit and shaping unit composition and drift and the shaping head of given shape, the upset of limit, hole and flatness problem can not occur in the time of can effectively guaranteeing the required distance much higher hole series products punching between, aperture hard to material, limit, Kong Bianyu hole, have that die cost is low, the production efficiency high.

The utility model is reasonable in design, is skillfully constructed, and effectively solves the nearlyer upset of limit, hole and the flatness problem that produces of Kong Yukong of the hard material product product of processing, can satisfy modern society and production to the high request of porous series products punching die.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1, a kind of porous series products of the utility model punching sizing continuous mould, comprise by upper bolster 1, the upper backboard 2 that contacts with upper bolster 1 lower surface, the punching unit 3 and the shaping unit 4 that contact with upper backboard 2 lower surfaces, by the counterdie that the lower bolster 5, lower bolster 6 and the die shoe 7 that contact with aspect from top to down form, described punching unit 3 comprises punching upper padding plate 8, punching train wheel bridge 9, punching stripper plate 10 and the punching holding pad 11 that contacts with aspect from top to down; Described shaping unit 4 comprises shaping upper padding plate 12, shaping train wheel bridge 13, shaping stripper plate 14 and the shaping holding pad 15 that contacts with aspect from top to down; Described punching holding pad 11 and shaping holding pad 15 are equipped with guide pin 16 and match with the guide pin bushing 17 of the corresponding setting of lower bolster 5, and those guide pins 16 and coordinating of guide pin bushing 17 are that patrix play the guiding role when descending; Described punching unit 3 is provided with a plurality of drifts 18, and on those drifts 18 and counterdie, the through hole 19 of corresponding setting matches, and 18 pairs of products to be processed of those drifts carry out inserting in corresponding through hole 19 after punching; Described shaping unit 4 is provided with a plurality of shapings 20, and on those shapings 20 and counterdie, the blind hole 21 of corresponding setting matches, and the product after 20 pairs punchings of those shapings carries out inserting in corresponding blind hole 21 after further shaping.

Referring to Fig. 2, the epimere of described drift 18, interlude and hypomere are stepped that diameter diminishes gradually, and rounding off between epimere and interlude, interlude and hypomere, the bottom end face is the indent arc, make drift 18 when carrying out punching towards processed products, the bottom end face can absorb the stress of hard material product effectively; When drift 18 came downwards to the hole top edge, the rounding off between drift 18 epimeres and interlude is the top edge of extruded hole well, prevented edge, the hole upset of product.

Referring to Fig. 3, epimere, interlude and the hypomere of described shaping 20 are stepped that diameter diminishes gradually, and between epimere and interlude, interlude and hypomere rounding off can be again the top edge of extruded hole well, the bottom end edge is that the cylindrical arc can make shaping 20 enter in the hole well, and then the flatness of product is adjusted.

Add man-hour, a roll bending material to be processed is placed in the end that unreels of the present utility model, by conveyer belt, sheet material to be processed is sent on lower bolster 6 corresponding to the counterdie of punching unit 3, and patrix is descending, treats machining sheet and carries out the punching operation; After the punching end of job, patrix is up, the sheet material after punching continue under the effect of conveyer belt to proceed to shaping unit 4 below; Patrix is again descending, and the sheet material after 4 pairs of punchings of shaping unit carries out shaping, and simultaneously, the sheet material to be processed of 3 pairs of next parts of punching unit carries out the punching operation; With this operation repeatedly.

In sum, the utility model is by above-mentioned structural design, disposable punching and the plastic operation of completing a plurality of holes, solve well the nearlyer upset of limit, hole and the flatness problem that produces of Kong Yukong of the hard material product product of processing, have that die cost is low, the production efficiency high, market value and huge market potential are widely arranged.

The above, only better enforcement of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the equivalent embodiment of equivalent variations, at this, all the technical solution of the utility model contents that do not break away from, just foundation technical spirit of the present utility model to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solutions of the utility model.
