Description
Technical field
The utility model relates to a kind of mosquito-repellent incense processing unit (plant), is specifically related to a kind of underframe catch and laminates perforating die.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die.Whether blanking die structure is reasonable, advanced, has a direct impact to production efficiency and the service life of blanking die itself and the safety, convenience etc. of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.Blanking die is mainly used in blanking and the punching of various sheet material, the working position of mould is the cutting edge of punch and matrix, withstand shocks during cutting edge work power, shearing force, bending force, and shear the strong friction power of material, thus the performance requirement to die point is mainly referred to the performance requirement of blanking die.Cold punching die can be divided into Plate-Type Blanking Dies (thickness of slab≤1.5mm) and Blanking thick plank mould (thickness of slab > 1.5mm) two kinds.At present, the production of most of mosquito-repellent incense is the mode of the punching press adopted.When processing mosquito-repellent incense, need, on underframe, catch is installed.Because the processing of long-time high load capacity, underframe catch becomes a kind of consumable accessory, needs to change in time.At present, underframe catch does not have shaping process equipment mostly, mostly adopts manual production, and not only efficiency is lower, and the precision of producing is lower, often needing secondary operations when changing, wasting time and energy.Therefore, consider the efficiency of machining accuracy and processing, adopt the processing mode of punching, the perforating die of design specialized.
Utility model content
The purpose of this utility model is to provide a kind of underframe catch to laminate perforating die, can carry out boring process, ensure the precision of processing and the efficiency of processing, process the underframe catch meeting Production requirement underframe catch.
For achieving the above object, the technical solution of the utility model is: underframe catch laminates perforating die, comprise die shoe and upper bolster, described die shoe is fixed with vertical guided mode bar, described die shoe is fixed with counterdie fixed head, described counterdie fixed head is provided with stripper, rubber spring is provided with between described stripper and counterdie fixed head, described counterdie fixed head is provided with a lower punch, offer central notch and limit notch in described lower punch, described die shoe is provided with the material road corresponding with central notch and limit notch; Described upper bolster is fixed with die shank, in described die shank, slip is provided with one and makes bar, float and be provided with one and re-pack in the lower end of described upper bolster, the described lower end re-packed is fixed with punch retainer, described punch retainer is provided with downward centre punching punch and limit piercing punch, the below of described punch retainer is fixed with pressing plate, and described pressing plate cross-sectional sizes is identical with the cross-sectional sizes of stripper.
When adopting technique scheme, drive die shank to move downward by drive unit, die shank drives upper bolster to move downward with beating together with bar in die shank.On the one hand, punch retainer fixing on upper bolster drives the pressing plate of below to compress the multilayer underframe catch be placed on stripper, plays and compresses and fixing effect.On the other hand, beat on bar acts on and re-pack in die shank, the centre punching punch on punch retainer and limit piercing punch is acted on by re-packing, by offering central notch and limit notch acting in conjunction in centre punching punch and limit piercing punch and lower punch, multilayer underframe catch completes center and lateral opening processing.After machining, under the return action of rubber spring, can jacking stripper, complete the operation of discharging.Novel structure of the present utility model, changes the processing mode of traditional underframe catch, and Multi-stacking compaction utilizes the mode of punching to process together, makes the peritreme of the underframe catch after processing neat, attractive in appearance.
Further, described in the upper end that re-packs protrude and be provided with one and hit ring, described strike ring is positioned at the below making bar.Strike ring is set, can allows and make bar and act on and hit on ring, concentrate stressed, and make to re-pack and be not easy to damage.
Further, the upper surface of described stripper is provided with alignment pin.This setting accurately can be located underframe catch by alignment pin.
Further, described upper bolster is provided with guide pin bushing, and the upper end of described guided mode bar is inserted in guide pin bushing.
Further, be provided with ejector in the middle part of described pressing plate, described ejector is fixed on punch retainer by liftout screw.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model underframe catch laminates perforating die embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model underframe catch laminates perforating die, comprises die shoe 1 and upper bolster 2, and die shoe 1 is fixed with vertical guided mode bar 3, upper bolster 2 is provided with guide pin bushing, and the upper end of described guided mode bar 3 is inserted in guide pin bushing 16.Die shoe 1 is fixed with counterdie fixed head 4, counterdie fixed head 4 is provided with stripper 5, is provided with rubber spring 6 between stripper 5 and counterdie fixed head 4, and the upper surface of stripper 5 is provided with alignment pin.This setting accurately can be located underframe catch by alignment pin.Counterdie fixed head 4 is provided with a lower punch 7, offers central notch and limit notch in lower punch 7, and die shoe 1 is provided with the material road corresponding with central notch and limit notch.Upper bolster 2 is fixed with die shank 9, sliding in die shank 9 is provided with one and makes bar 8, floats and be provided with one and re-pack in the lower end of upper bolster 2, and the upper end re-packed is protruded and is provided with one and hits ring 15, hits the below that ring 15 is positioned at dozen bar 8.Arrange and hit ring 15, can allow and make bar 8 and act on and hit on ring 15, concentrate stressed, and make to re-pack and be not easy to damage.The lower end re-packed is fixed with punch retainer 11, and punch retainer 11 is provided with downward centre punching punch 12 and limit piercing punch 13, and the below of punch retainer 11 is fixed with pressing plate 14, and pressing plate 14 cross-sectional sizes is identical with the cross-sectional sizes of stripper 5.Be provided with ejector 18 in the middle part of pressing plate 14, described ejector 18 is fixed on punch retainer 11 by liftout screw 17.
