Abstract
The utility model discloses an adjustable die, wherein a female die in a lower die is embedded into a female die fixing sleeve, and the outer peripheral surface of the female die fixing sleeve is provided with an adjusting screw; the male die of the upper die is arranged in the male die fixing sleeve and is fixed through the transverse pin; the male die fixing sleeve is arranged in the male die fixing seat and is fixed through a top thread; the lower end part of the male die fixing seat is embedded into a discharging sleeve, and a discharging plate is fixed at the lower end of the discharging sleeve; in the lower extreme embedding of discharge bar was unloaded the cover, the upper end of discharge bar passed the downthehole of terrace die fixing base, and the discharge bar can slide in the downthehole of terrace die fixing base. The beneficial effects are that: the upper die of the die is adjusted for plane torsion in the Z-axis direction of the reference hole through the special-shaped hole, the lower die is adjusted through the adjusting screw, the requirement for parts with high blanking precision is effectively met, the rejection rate of the parts is reduced, the assembling and adjusting processes of the die are simplified, and the production cost and the workload of operators are reduced.
Description
Technical field
The utility model relates to a kind of mould structure, and particularly relating to a kind of rushed shape has the upper and lower mould adjustable mould of status requirement to datum hole.
Background technology
In stamping, often there will be the situation of stamping-out irregularly-shaped hole, profiled holes and most typical different being of circular hole: the position deviation of profiled holes also there will be the plane around Z axis to turn to except the position skew of X, Y direction.In watch part stamping-out, irregularly-shaped hole requires to be generally 0.04-0.06mm with respect to position degree and the profile tolerance of datum hole.When stamping-out as occur overproof can be with regulating the method for locating pin position improve.And be the vital part of 0.01-0.02mm for profiled holes relative datum hole location and profile tolerance requirement, its punching precision can not be significantly improved by above-mentioned means.If particularly existing mold repeatedly repair only can cause the hole site loss of significance of original nail, and can make processing cost and installation time be multiplied.This situation especially easily occurs during tiny and out-of-shape in special-shaped size, often causes part to scrap.Fig. 1 is existing mold schematic diagram, as adopted existing mold stamping-out, when occurrence positions degree or profile tolerance are when overproof, need to upper/lower die plate be carried out to repeatedly repair by mach method, until position and profile require qualified carry out die assembly, examination punching again; Repeated multiple times until go out qualified parts.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of adjustable mould structure of simplifying production process, reducing scrappage is provided.
The technical scheme that the utility model adopts is: a kind of adjustable mould, comprises upper die and lower die; Described counterdie comprises, die fixed cover and die; Described die embeds in die fixed cover, and the outer peripheral face of described die fixed cover is provided with adjustment screw; Described patrix comprises, stripper, discharging cover, discharge arm, material beating device, jackscrew, punch holder, punch fixed cover and punch; Described punch packs in punch fixed cover, and is fixed by lateral pin; Punch fixed cover packs in punch holder, and fixes by jackscrew; The bottom of described punch holder embeds in discharging cover, and the lower end of described discharging cover is fixed with stripper; The lower end of described discharge arm embeds in discharging cover, and the upper end of discharge arm is through in the hole of punch holder, and discharge arm can slide in the hole of punch holder.
Described adjustment screw has four, is evenly arranged on the outer peripheral face of die fixed cover.
The lower end of described punch fixed cover mills out two parallel planes.
The beneficial effects of the utility model are: upper mould is adjusted the plane torsion in datum hole Z-direction by irregularly-shaped hole, counterdie regulates by adjustment screw, efficiently solve the part requirement that punching precision is high, reduced part scrappage, die assembly, adjustment process are simplified, and have reduced production cost and operator's workload.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figures 1 to 5, the utility model adjustable mould, comprises upper die and lower die, and upper and lower mould is adjustable structure; Described counterdie comprises, die fixed cover 1 and die 9; Described die 9 embeds in die fixed cover 1, and the outer peripheral face of described die fixed cover 1 is evenly provided with four adjustment screw 12, withstands die fixed cover 1 respectively from four direction; When abnormity and datum hole exist skew in X, Y-direction to adjust, only screw need be tightened by a small margin or is loosened the relative position that is set in die 9 on die fixed cover 1 and patrix with regard to adjustable, examination is rushed after qualified four screws is tightened respectively fixing.
Described patrix comprises, stripper 2, discharging cover 3, discharge arm 4, material beating device 5, jackscrew 6, punch holder 7, punch fixed cover 8 and punch 11; Described punch 11 packs in punch fixed cover 8, on punch fixed cover 8 sidewalls, is formed with a through hole, and lateral pin 10 is through through hole solid punch 11; Punch fixed cover 8 packs in punch holder 7, the lower end of described punch fixed cover 8 mills out two parallel planes 13, when examination is rushed, as found there is Z-direction and rotate in abnormity, can be under the prerequisite of not dismounting mould with pliers or other specific purpose tools, clamp two planes 13 on punch fixed cover 8 left or the moving certain angle of turning right, punch 11 also rotates thereupon, the angle of abnormity is also adjusted thereupon, fixing with tightening jackscrew 6 after adjusting.The bottom of described punch holder 7 embeds in discharging cover 3, and the lower end of described discharging cover 3 is fixed with stripper 2; The lower end of described discharge arm 4 embeds in discharging cover 3, and the upper end of discharge arm 4 is through in the hole of punch holder 7, and discharge arm 4 can slide in the hole of punch holder 7.
Working method of the present utility model is: when stamping-out starts, patrix is descending, punch holder 7 assemblies are descending together with overlapping 3 assemblies with discharging, more and more approach die 9, when punch 11 will soon contact with die 9, stripper 2 is fitted and can not with patrix, move down again with piece surface, along with continuing descending discharging cover 3, patrix by knockout rod 4, material beating device 5 is promoted to top, until punch 11 will start backhaul after part punching thoroughly, the upper end of material beating device 5 touches the whippletree of punch press top, material beating device 5 moves downward immediately, knockout rod 4 is pushed, knockout rod 4 drives discharging cover 3 to move down along the hole on punch holder 7, until material is unloaded from punch 11, complete stamping-out one time.
