Description
Technical field
The utility model belongs to mould applications, relates to five metals continuous stamping die, particularly the structure of die-cut stub bar in a kind of metal stamping die.
Background technology
In current most companies progressive die, there is no the action of die-cut stub bar, all direct punching presses, its material strip head is gone out unnecessary waste material hand and is taken out mould or air gun and blow to mould outside, although can make in mould without waste material by these two kinds of methods, punching press smoothly, but there is following problem: stretching out one's hand and take waste material out in mould, is breakneck action, and its personal safety cannot guarantee; Another kind method blows out mould with air gun by unnecessary waste material, although no problem, to the personnel of half-hearted work, also be breakneck, do not note a little waste material to blow to some forming parts, guide pillar hole or product the inside, will make mould parts damage by pressure, even explode mould, product surface is weighed wounded, increased the mould difficulty that repairs a die, reduced output, improved product fraction defective and producing cost, Master Cost, also cannot reach client's quality requirements.
Along with the speed of the Kuai speed Fa Zhan ﹐ mould punching of Tool and Die Technology constantly promotes, in its designing mould, consider fully personal safety, the drawing velocity of mould, and the quality of punching press product, in the life-span of mould itself, this just requires mould to have corresponding method to dissolve.
Utility model content
The purpose of this utility model is to solve above-mentioned practical problem, before progressive die punching press, add the operation of die-cut stub bar together, stub bar is thrust and directly discharge and do not stay in the progressive die from the counterdie edge of a knife, and die-cut complete stub bar back punching head can automatically reset, prevent continuous quadratic punching press or hinder material strip and pass through, one continuous punching operation being carried out smoothly, because stub bar removes completely, in the progressive die, can not retain unnecessary waste material head, need not manually go cleaning yet.The safety work that so improves mould, safety in production, makes operating personnel's high efficiency, the fulfiling assignment of high-quality.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme: the structure of cropping in a kind of metal stamping die, comprise upper die component and counterdie part, described upper die component sets gradually upper bolster, upper padding plate, train wheel bridge from top to bottom, and described counterdie part sets gradually lower bolster, lower bolster, die shoe from top to bottom; On described train wheel bridge, drift is set, the counterdie edge of a knife is set on described lower bolster; Described upper bolster is fixedly connected with drift by two contour screws, and described contour screw upper end arranges back-moving spring, and middle-end is through upper padding plate and part train wheel bridge, and drift is fixed in lower end, and described drift upper end arranges interior top sliding block; Described upper padding plate arranges a chute, and thruster slide block is set in described chute; The side that described thruster slide block extends chute arranges spacing hole, and is connected with upper bolster by stop screw; The side of thruster slide block in chute contacts with interior top sliding block, concavo-convex with knuckle that the lower end of the side that thruster slide block contacts with interior top sliding block and interior top sliding block upper end are arranged to cooperatively interact, thruster slide block can be in chute internal top sliding block transverse shifting mutually.
The side that described thruster slide block extends chute is fixedly connected with thruster screw;
Between described train wheel bridge and lower bolster, set gradually from top to bottom de-backboard and stripper plate;
The hole that allows drift pass through is set on described de-backboard and stripper plate;
Described counterdie edge of a knife position is corresponding with drift position;
On described lower bolster and die shoe, corresponding counterdie knife-edge part has the through hole (not showing in accompanying drawing) of waste discharge stub bar.
Operation principle: concavo-convex with knuckle of being arranged to cooperatively interact due to thruster slide block lower end and interior top sliding block upper end, so relatively moving of thruster slide block and interior top sliding block can lengthen or shorten drift.During die opening state (as shown in Figure 1), the fit system of thruster slide block and interior top sliding block makes drift in adding long status, back-moving spring on contour screw is in elongated condition, stop screw is positioned at the spacing hole leftmost side, and stop screw is now in tightening state (thereby thruster slide block and upper bolster can be fastened prevent thruster slide block from moving stop back-moving spring to reset); In mould closing course, can smoothly stub bar be thrust to (as shown in Figure 2) and discharge from the counterdie edge of a knife.When completing after die-cut operation, unclamp stop screw (can move thereby thruster slide block and upper bolster are unclamped) in chute, back-moving spring reset can drive thruster slide block to be moved to the left, when encounter after stop screw the spacing hole rightmost side, thruster slide block stops mobile, now thruster slide block shortens and the concordant stripper plate of head drift with the fit system (as shown in Figure 3) of interior top sliding block, thereby makes drift cannot be die-cut to material, has avoided secondary punch; The folding condition of last mould as shown in Figure 4.When next coiled tape is come, only need thruster slide block be moved right by thruster screw until stop screw is encountered in the spacing hole leftmost side and by stop screw tightening, due to the relatively moving, coordinate of thruster slide block and interior top sliding block, drift is in adding long status, and mould is got back to again state as shown in Figure 1.
Beneficial effect: the utility model is simple and reasonable for structure, before continuous punching, head unnecessary material strip is cut away and discharges the progressive die, accomplished without waste material punching press, without follow-up labor cleaning, guaranteed fully personal safety, and actually accomplished safety work, safety in production, has also guaranteed the quality of punching press product and the speed of punching press.
