Description
Technical field
The utility model relates to a kind of diel, specifically for the punching press of stainless steel coated flitch.
Background technology
In punching press at present for stainless steel coated flitch, often need very thin stainless steel coated flitch to carry out deep drawing, this deep drawing is very easy to cause the drawing crack of flitch to damage; The yields during punching stretch of the therefore ultra-thin flitch of prior art in stainless steel coated flitch is lower; Simultaneously due to the complexity of product, the processing for this series products often adopts gradation stamping-out and subpunch fenestra, then rushes straight trough, and the problem often due to mould structure design during this causes burn failure, is difficult to reach design accuracy requirement simultaneously.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of stainless steel coated precise punching die, its Stability Analysis of Structures, not fragile during production; Product Precision is high, and the yields for the punching stretch process of ultra-thin flitch is higher.
The utility model solves the technical scheme that its technical problem adopts: stainless steel coated precise punching die, comprises upper die and lower die and locating core; Described patrix comprises upper bolster, upper mould fixed plate and stripper; Described counterdie comprises die shoe; Guide pin bushing A and the guide pillar A of mutually coupling are installed between described upper mould fixed plate and stripper, guide pin bushing B and guide pillar B that three parafacies mate mutually are installed between upper bolster and die shoe; Three secondary guide pin bushing A and guide pillar A are installed between described upper mould fixed plate and stripper;
Described upper mould fixed plate is provided with elastic tripper, and described elastic tripper comprises described stripper, also comprises discharging rubber; Described stripper is connected on upper mould fixed plate, and described discharging rubber is placed between upper mould fixed plate and stripper;
Also comprise the drift being arranged on upper mould fixed plate lower surface; On described counterdie, the below of corresponding described drift is provided with die; The overlay film flitch of punching press is needed to be placed between described stripper and die; The position of the corresponding drift of described stripper is provided with die cavity, and described drift is through overlay film flitch described in described die cavity punching press; The center of described die is the through hole of up/down perforation, and push rod holds out against the lower surface of described overlay film flitch from bottom to top; The punching press bottom surface of described drift and the end face of described push rod are the shape of the stamping surface coordinating described overlay film flitch;
Described die shoe is fixed in presser's station by bolt and pressing plate; Arrange Buffer Unit between described die shoe and presser's station, described Buffer Unit comprises spaced top board and fagging, has vertically been arranged side by side multilayer rubber cushion, is separated between rubber mat by iron plate between top board and fagging.
Further: the punching press bottom surface of described drift is made up of upper and lower; More described bottom, described top is given prominence to, and forms the bending line of a "the" shape between described upper and lower.
Stainless steel coated precise punching die described in the utility model, it has the following advantages:
1, upper and lower die holder of the present utility model is by three secondary guide pillars and bushes location, adds the stability of mould use and the ease for operation of maintenance; By setting up three secondary guide pin bushing and guide pillars between stripper and upper mould fixed plate, thus ensure that up rightness and the service precision of patrix;
2, achieve the drawing to flitch by the relative motion of drift and die in punching course of the present utility model, compress peripheral material during drawing with stripper, the way of flowing internal material realizes shaping in advance; Make the large plane bottom stretching first produce work hardening, eliminate material internal stress, increase the percentage elongation of material, thus the yields of drawing and forming is promoted, the degree of depth drawing of ultra-thin flitch can be adapted to reliably;
3, be connected with top board below die shoe of the present utility model, between top board and fagging, be provided with multilayer rubber cushion; When mould relatively compresses up and down and starts, rubber blanket under top board starts compression, when reaching shaping compacted position, pressure-pad-force can not change, reach pressure-pad-force reach certain numerical value after substantially constant effect, keep constant, avoid the phenomenon that pressure-pad-force increases with the increase of stroke, improve product surface quality, reduce percent defective.
