According to products punched through the side punching mechanism, waste can be automatically discharged out, and no burrs are generated.
Description
Technical field
The utility model relates to moulds of industrial equipment, is specifically related to a kind of side punching mechanism.
Background technology
In the prior art, conventionally will carry out side punching operation to some sheet metal components, existing punching die can the bad discharge due to the waste material that side punching produces, and take out by hand waste material, easily produces burr, thereby affect product quality in taking-up process.
Utility model content
The purpose of this utility model is: a kind of side punching mechanism is provided, and the product that adopts this mechanism to go out, waste material can be discharged automatically, can not produce burr.
A kind of side punching mechanism is provided, comprises upper and lower die holder, on described die shoe, be arranged with by piece, in the described inner side by piece, be bolted bevelled the first slide block of tool, slider side wall is provided with punching concave die; At the middle part of die shoe, be provided with the second slide block, pilot pin, punched hole punching needle, on described punching punching concave die, be provided with waste material crushing block; By piece, be provided with waste material and return spring assembly; The bottom surface of described upper bolster is provided with train wheel bridge, is provided with the second drive block that a upper bolster is connected in train wheel bridge, and the below of train wheel bridge is provided with stripper, is provided with guide rod and discharging spring between stripper and upper bolster; Both sides, bottom surface at described upper bolster are provided with drive block fixed head, are provided with first drive block corresponding with described the first slide block inclined-plane on described drive block fixed head.The end of the first drive block has the inclined-plane contrary with described the first sliding block inclined face tilt angle.
This mechanism course of work is divided four-stage, and 1, the binder stage; Stripper is first pressed in product on die by spring force, and 2, cutting edge puts in place; Then the first drive block moves downward, the inclined-plane of its lower end touches the first slide block inclined-plane, under the effect of side force, the first slide block moves to mold center, and drive block continues to move downward, by the time the inclined-plane of its inclined-plane and slide block departs from, after the straight body face contact of the straight body face slide block of its inner side, the side direction driving force that acts on slide block disappears, and slide block just no longer moves to mold center, now it just touch product, and the cutting edge of namely slide block punching has arrived the position of appointment; 3, slide block binder; And then, same principle the second drive block drives the first slide block to the second slide block movement of correspondence, and stripper, under the effect of spring, is pushed down product in the direction of corresponding slide block; 4, punching completes; The first slide block is to continuing outwards motion, and punched hole punching needle has completed punching action.
This mechanism, by the mutual action on two inclined-planes, realizes red needle and carries out from inside to outside punching; The waste material producing is return at waste material crushing block and waste material under the effect of spring assembly and is taken out of and drop below die shoe, thereby has guaranteed the punching quality of product.
Accompanying drawing explanation
Fig. 1 is the utility model structure cutaway view.
The specific embodiment
Shown in Fig. 1: design a kind of side punching mechanism, be provided with upper bolster 1, die shoe 4, on described die shoe 4, be arranged with by piece 9, in the described inner side by piece 9, be bolted bevelled the first slide block 10, the first slide block 10 sidewalls of tool and be provided with punching concave die 11; At the middle part of die shoe 4, be provided with the second slide block 18, pilot pin 15, punched hole punching needle 16, on described punching punching concave die 11, be provided with waste material crushing block 14; By piece 9, be provided with the waste material corresponding with it and return spring assembly 17; The bottom surface of described upper bolster 1 is provided with train wheel bridge 2, in train wheel bridge 2, be provided with the second drive block 12 that a upper bolster 1 is connected, the below of train wheel bridge 2 is provided with stripper 3, between stripper 3 and upper bolster 1, be provided with guide rod and discharging spring 13, both sides, bottom surface at described upper bolster are provided with drive block fixed head 7, the end that is provided with first drive block 8, the first drive blocks 8 corresponding with the inclined-plane of described slide block 10 on described drive block fixed head 7 has the inclined-plane contrary with the angle of inclination, inclined-plane of described slide block 10.
In above-mentioned side punching mechanism, below die shoe 4, be provided with lower cushion block 5 and bottom plate 6.
This mechanism course of work is divided four-stage:
One, the binder stage; Stripper 3 is first pressed in product on die by spring force;
Two, cutting edge puts in place; Then the first drive block 8 moves downward, the inclined-plane of its lower end touches the inclined surface of the first slide block 10, under the effect of side force, the motion of the first slide block 10Xiang mold center, the first drive block 8 continues to move downward, by the time the inclined-plane of its inclined-plane and the first slide block 10 departs from, after the straight body face of its inner side contacts with the straight body face of slide block 10, the side direction driving force that acts on slide block 10 disappears, slide block 10 just no longer moves to mold center, now it just touch product, and the cutting edge of namely slide block punching has arrived the position of appointment;
Three, slide block binder; And then, same principle the second drive block 12 drives the first slide block 10 to the second slide block 18 motions of correspondence, and stripper 3, under the effect of discharging spring 13, is pushed down product in the direction of corresponding slide block 18;
Four, punching completes; The first slide block 10 is to continuing outwards motion, and punched hole punching needle 16 completes punching action.
Five, waste material is discharged: the waste material producing is return at waste material crushing block and waste material under the effect of spring assembly and taken out of and drop below die shoe, thereby has guaranteed the punching quality of product.
