Abstract

The utility model discloses a die for separating a precision sheet metal part from a material strip. The die comprises an upper male die (39) and a lower male die (40) and is characterized in that a blanking male die (29) penetrating through a male die fixing plate (4), a discharging plate base plate (5) and a discharging plate (6) is fixed to the discharging plate (6) through a hexagon socket screw (12), a fixing block (15) and a pre-cutting male die (14) are fixed to a concave formwork (7) through a second hexagon socket screw (16), and a die disengaging groove (33) is fixed to a concave formwork base plate (8) through a ninth hexagon socket screw (34). According to the die for separating the precision sheet metal part from the material strip, one pre-cutting step is additionally arranged, the requirement that the cutting position of the precision sheet metal part has no burr is met, the service life of cut male-female die in the last step is prolonged, maintenance cost is reduced, and the working efficiency of the die is improved.

Description

Accurate sheet metal part and material strip peel of mould

Technical field

The utility model belongs to diel, particularly a kind of accurate metal plate parts and material strip peel of mould.

Background technology

Current accurate metal plate parts separates a stamping-out of employing and separates on material strip with connection rib, mold work a period of time just there will be burr large, is difficult to meet the following requirement of burr 0.02mm.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, a kind of accurate sheet metal part and material strip peel of mould that can meet the burr requirement is provided.

The technical scheme that the utility model technical solution problem adopts is: a kind of accurate metal plate parts and material strip peel of mould comprise upper male mould and lower punch; Upper male mould comprises the upper bolster cover plate, and upper bolster, punch be backing plate, punch retainer, stripper backing plate and stripper fixedly; Lower cavity die comprises die shoe, concave template backing plate and concave template; It is characterized in that fixing one with hexagon socket head cap screw one on stripper cuts die and fixed block in advance; Fix a blanking punch be through in punch retainer, stripper backing plate and stripper with hexagon socket head cap screw three on punch retainer; At concave template with hexagon socket head cap screw two by fixed block with cut in advance punch and be fixed on the concave template backing plate; With hexagon socket head cap screw nine fixedly the stamping die groove on the concave template backing plate.

The beneficial effects of the utility model are: this utility model increases by a step cuts in advance and not only can meet the carrot-free requirement of accurate metal plate parts cut-off part, has also extended the life-span that punch-die is cut off in final step, has reduced maintenance cost, has improved mold work efficiency.

The specific embodiment

Embodiment, with reference to accompanying drawing, a kind of accurate metal plate parts and material strip peel of mould, comprise upper male mould 39 and lower punch 40; Upper male mould 39 comprises upper bolster cover plate 1, and upper bolster 2, punch be backing plate 3, punch retainer 4, stripper backing plate 5 and stripper 6 fixedly; Lower cavity die 40 comprises die shoe 9, concave template backing plate 8 and concave template 7; It is characterized in that fixing one with hexagon socket head cap screw 1 on stripper 6 cuts die 11 and fixed block 13 in advance; Fixedly be through a blanking punch 29 in punch retainer 4, stripper backing plate 5 and stripper 6 on punch retainer 3 with hexagon socket head cap screw 3 21; At concave template 7 use hexagon socket head cap screw 2 16 fixed blocks 15, cut in advance punch 14 on concave template backing plate 8; With hexagon socket head cap screw 9 34 fixedly stamping die groove 33 on concave template backing plate 8.Between upper bolster cover plate 1 and upper bolster 2, hexagon socket head cap screw 6 24 is connected, between spring 1 also is housed, plug screw 1 is equipped with in spring one 20 upper ends; Upper bolster 2 is fixed together with punch retainer backing plate 3, punch retainer 4 use hexagon socket head cap screws 4 22; Fix a little guide pillar 17 with hexagon socket head cap screw 7 25 on punch retainer backing plate 3, little guide pillar 17 is through in the little guide pillar guide pin bushing 1 in punch retainer 4, stripper backing plate 5 and stripper 6; Be threaded with stripper bolt 27 with hexagon socket head cap screw 8 28, punch retainer backing plate 3, punch retainer 4, stripper backing plate 5 and stripper 6 are coupled together; Be fixed together with hexagon socket head cap screw 5 23 between stripper backing plate 5 and stripper 6, correcting nail 30 is housed on stripper 6; Die shoe backing plate 10 is fixed together with lower bolster 9, on lower bolster 9, with hexagon socket head cap screw 10, concave template backing plate 8 and concave template 7 is fixed together; Between alignment pin 37 also is housed, little guide pillar guide pin bushing 2 41 and platform material pin 32 are housed on concave template 7, below platform material pin 32, in concave template backing plate 8 and lower bolster 9, spring 2 36 is housed, plug screw 2 38 is equipped with in spring 2 36 lower ends; Large guide pillar 26 is housed between lower bolster 9 and upper bolster 2, in large guide pillar 26, large guide pillar assembly 31 is housed, be fixed on lower bolster 9 with bolt 41 in large guide pillar assembly 31 lower ends.

Part of the present utility model separates with material strip: carry out the v-shaped bending back at part and append a step and cut in advance die 11, cut in advance punch 14, part with expect that the technique handle place be connected is oppositely die-cut from the burr side of part, when last blanking punch 29, blanking die 33 cut off material strip, cutting parts technique handle place will can not produce burr.

The specific works process is as follows: when mould is worked to bottom dead centre, the first correcting in the gathering sill of cutting in advance punch 14 of tiny connection rib of material strip, when mold work arrives bottom dead centre, cut in advance punch 14 and will on the connection rib of material strip incision stripper 6, cut in advance the interior certain depth of die 11, now part still is connected on material strip and works on, after last blanking punch 29, blanking die 33 cut off, part separates with material strip, can realize that Cutting process handle place is without burr.
