Abstract
The utility model relates to a machining device of brake pad steel backs, in particular to a shear type blanking mold. The shear type blanking mold comprises a male mold and a female mold. The male mold is located on the lower portion of an upper mold seat through bolts, and the female mold is arranged on the upper portion of a lower mold seat. The shear type blanking mold is characterized in that a cutting edge of the male mold is step-type, a cutting edge of the female mold is round-corner-type, and locating pins are arranged inside the male mold. A fixing plate which fixes the male mold is arranged on the lower portion of the upper mold seat on the outer periphery of the male mold, and a polyurethane plate and a stripper plate which are fixedly connected with the upper mold seat through bolts are sequentially arranged on the lower portion of the fixing plate. Material-abutting pieces are inlaid inside the female mold, the material-abutting pieces are connected with the lower mold seat through bolts, a pilot pin is arranged inside the fixing plate, and the pilot pin passes through the polyurethane plate and the stripper plate and is matched with a female mold small gap. A lower mold base pad is arranged on the lower portion of the lower mold seat, and the lower mold base pad is connected with a material-abutting device through a material-abutting rod, and therefore the shear type blanking mold is reasonable in design, practical and convenient.
Description
(1) technical field
The utility model relates to the brake block steel back processing unit (plant), particularly a kind of shearing blanking die.
(2) background technology
Be to guarantee euphotic belt, the production technology of most of steel backing all is first blanking, again refine, but owing to error being arranged when locating in two steps, cause the gap inclined to one side, steel backing is asymmetric or the refine face degree of depth is inconsistent but also can cause.
(3) summary of the invention
The utility model provides a kind of reasonable in design in order to remedy the deficiencies in the prior art, and structure is shearing blanking die easily.
The utility model is achieved by the following technical solution:
A kind of shearing blanking die comprises punch and die, and in the upper bolster bottom, die is arranged at die shoe top to punch, it is characterized in that by Bolt to position: described punch cutting edge is step, and there is radiused at the cutting edge of die place, and punch inside is provided with alignment pin; The upper bolster bottom of described punch periphery is provided with the fixed head of solid punch, and the fixed head bottom is disposed with polyurethane sheet and the stripper plate that is bolted to connection upper bolster; Described die inside is inlaid with ejection block, and ejection block is bolted die shoe; Be provided with pilot pin in the described fixed head, pilot pin passes the little matched in clearance of polyurethane sheet and stripper plate and die; Described die shoe bottom is provided with the counterdie backing plate, and lower film backing plate connects Lifting Device by ejector beam.
Between described upper bolster and the punch, be respectively arranged with convex mould pad and die backing plate between die shoe and the die; Described Lifting Device comprises polyurethane sheet A and is positioned at the up and down die pad at two ends of polyurethane sheet A; Described die epimere periphery is provided with cuff.
The beneficial effects of the utility model are: the shearing blanking die of this utility model is simple in structure, practical and convenient, can finish stamping-out one time, reaches the requirement of euphotic belt in blanking, is suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is punch blade shape schematic diagram of the present utility model;
Accompanying drawing 3 is cutting edge of die shape schematic diagram of the present utility model;
Among the figure, 1 punch, 2 convex mould pads, 3 fixed heads, 4 upper bolsters, 5 polyurethane sheets, 6 stripper plates, 7 cuffs, 8 die backing plates, 9 die shoes, 10 times film backing plates, 11 die pads, 12 polyurethane sheet A, 13 alignment pins, 14 pilot pins, 15 ejection block, 16 dies, 17 ejector beams.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises punch 1 and die 16, and in upper bolster 4 bottoms, die 16 is arranged at die shoe 9 tops to punch 1, it is characterized in that by Bolt to position: described punch 1 cutting edge is step, and there is radiused at die 16 cutting edge places, and punch 1 inside is provided with alignment pin 13; Upper bolster 4 bottoms of described punch 1 periphery are provided with the fixed head 3 of solid punch 1, and fixed head 3 bottoms are disposed with polyurethane sheet 5 and the stripper plate 6 that is bolted to connection upper bolster 4; Described die 16 inside are inlaid with ejection block 15, and ejection block 15 is bolted die shoe 9; Be provided with pilot pin 14 in the described fixed head 3, pilot pin 14 passes polyurethane sheet 5 and stripper plate 6 and die 16 little matched in clearance; Described die shoe 9 bottoms are provided with counterdie backing plate 10, and lower film backing plate 10 connects Lifting Device by ejector beam 17; Between described upper bolster 4 and the punch 1, be respectively arranged with convex mould pad 2 and die backing plate 8 between die shoe 9 and the die 16; Described Lifting Device comprises polyurethane sheet A 12 and is positioned at the up and down die pad 11 at two ends of polyurethane sheet A12; Described die 16 epimere peripheries are provided with cuff 7.
Adopt shearing blanking die of the present utility model, punch 1 profile is done larger, and the upper blade notch portion is made step.During work steel backing is placed on the die 16, with die 16 positioner coarse positionings, punch press work drives punch 1 and moves downward, die 16 at first contacts pilot pin 14 and carries out the gap correcting, then continue to move downward to connect, alignment pin 13 touches steel plate hole and carries out correcting, then contact steel plate carries out blanking, die 16 and punch 1 acting in conjunction are sheared the purpose that reaches deburring to workpiece during blanking (has step because of punch 1, there is fillet at die 16 cutting edge places, protruding, die is when closure contact workpiece, to its effect that produces an extruding, the power of this extruding all works to the whole side of workpiece, thereby has improved the euphotic belt of workpiece), during to the punch press lower dead center, steel backing is in die 16 interior moulding; Punch press resets and drives punch 1 rising, steel backing rises with ejection block 15 in die 16 die cavities, the die cavity of die 16 is got steel backing in Lifting Device work during to certain altitude, simultaneously polyurethane sheet 5 resiliences hold up stripper plate 6, stripper plate 6 resets and drives plate and protruding film 1 and die 16 disengagings, finishes a punching press.
