Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of punching unit combination mould.
Background technology
Present conventional perforating die has following two kinds: a kind of for the mould bases punching die is arranged, the mould bases of the type mould adopts guide pillar, guide pin bushing to connect upper bolster and die shoe usually, all be fixing dead them between patrix and upper bolster, counterdie and the die shoe, form an integral body---immutable integral body with alignment pin and screw.The mould bases punching die is arranged through being commonly used in once on the stamping parts in a plurality of holes, this mould is easy to scrap under following situation: the distance of (1) Kong Yukong is constant, and the change in size in hole; (2) size constancy in hole, and pitch-row changes; (3) size in pitch-row and hole all changes.Another kind of is no mould bases punching die, fixing dead them between the patrix of the type mould and upper bolster, counterdie and the die shoe with alignment pin or screw, and do not have mould bases to connect between upper bolster and the die shoe, can only rely on the gap of manually coming between the upper and lower mould, then upper and lower die holder is separately fixed on the slide block and workbench of forcing press.No mould bases punching die only is suitable for the single hole punching, being that a hole is once dashed in the forcing press action, is the same if a stamping parts has the size in a plurality of holes and hole, when adopting the type die punching, need repeatedly the location just can finish this stamping parts, and the distance between the Kong Yukong guarantees not too easily, if a stamping parts has a plurality of holes, and the size in hole is when different, when adopting the type mould to come punching, not only time-consuming, the distance between the Kong Yukong also guarantees not too easily.
The utility model content
At the problems referred to above, the purpose of this utility model has been to adopt a kind of simple in structure, high efficiency, punching unit combination mould that accuracy rate is high.
In order to achieve the above object, the technical solution of the utility model is to have adopted a kind of punching unit combination mould, the support body of this assembling die is the segmental support structure with side horizontal opening, be fixed with the die grip block on the underarm termination of the opening part of segmental support, be fixed with die on the die grip block, the upper arm termination of the opening part of segmental support is provided with vertical through hole, slidable fit has punch case in the through hole, the top mouth of punch case is provided with the flange edge, be coated with back-moving spring between the edge, hole of flange edge and through hole, slide in the punch case and be coated with punch, the punch position is corresponding mutually with the position of die, the top of punch is equipped with taping block, is provided with elastomeric layer around the punch between taping block and the flange edge.
Described back-moving spring is the taper back-moving spring.
Described elastomeric layer is the elastic polyurethane body.
Below die, be provided with waste channel.
The upper arm termination of the opening part of the segmental support of punching die of the present utility model is provided with vertical through hole, slidable fit has punch case in the through hole, slide in the punch case and be coated with punch, the punch position is corresponding mutually with the position of die, and the top of punch is equipped with taping block.Use the advantage of punching unit combination mould of the present utility model as follows: 1, adaptability is strong: they dash convenient and swift as numerical control, and efficient is leapt high more than numerical control; 2, versatility is good: protruding, the die of every kind of model punching unit can be replaced by another kind of punching size fast from a kind of punching size; 3, easy to use: as when the punching unit uses, to put, promptly press, also need not connect, directly hit getting final product punching with slide block with the slide block of forcing press without pressing plate toward press bench one; 4, safeguard simply: because the punching unit is a normal structure, so mould is easy to assembly, protruding, die is changed rapidly, and the upper and lower cutting edge sharpening of mould is simple, and general skilled worker just can be competent at; 5, utilization rate height: the punching unit can use repeatedly, constantly forms new assembling die, produces needs to satisfy, and the phenomenon of conventional punch die " dead mould " can not occur.The utility model is particularly suitable for many kinds, the stamping parts production of small batch, so they are widely used in industries such as automobile, agricultural machinery, elevator, switch, electric welding machine, household electrical appliance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the support body of punching unit combination mould of the present utility model is the segmental support structure with side horizontal opening, be fixed with die grip block 2 on the underarm termination of the opening part of segmental support 1, be fixed with die 3 on the die grip block 2, the upper arm termination of the opening part of segmental support 1 is provided with vertical through hole, slidable fit has punch case 4 in the through hole, the top mouth of punch case 4 is provided with flange along 5, flange along 5 and the hole of through hole between 6, be coated with back-moving spring 7, slide in the punch case 4 and be coated with punch 8, punch 8 positions are corresponding mutually with the position of die 3, the top of punch 8 is equipped with taping block 9, taping block 9 and flange are provided with elastomeric layer 10 on every side along the punch 8 between 5, and the back-moving spring 7 in the present embodiment is the taper back-moving spring, and elastomeric layer 10 is the elastic polyurethane body.Below die 8, be provided with waste channel 11.
During use, under the effect of press ram, taping block 9, punch 8, elastic polyurethane body 10, punch case 4 descend simultaneously with press ram, back-moving spring 7 begins compression, press ram continues to descend, punch case 4 at first contacts plate, and 10 distortion of elastic polyurethane body progressively increase, and punch 8 descends simultaneously and carries out punching.When press ram rose, elastic polyurethane body 10 restored to the original state gradually, and under the effect of punch case 4, punch 8 breaks away from plates,, finished one-off hole-piercing and processed punch case 4, punch 8, elastic polyurethane body 10, and taping block 9 jack-up by back-moving spring 7.
