The lower edge folding and stretching die structure is characterized in that an upper die base comprises an upper die plate, a stretching female die is arranged below the upper die plate, and an edge folding female die is arranged outside the stretching female die; a lower die base comprises a lower die plate, a stretching male die matched with the stretching female die is arranged on the lower die plate, an edge folding male die matched with the edge folding female die is arranged outside the stretching male die, a material pressing plate is arranged below the edge folding male die, a sliding type material ejector plate is arranged between the stretching female die and the edge folding female die, and a spring is arranged between the material ejector plate and the upper die plate. The edge folding female die and a material pressing and ejecting mechanism are additionally installed on the periphery of the stretching female die, a one-off stretching and edge folding accomplishing mechanism of the edge folding male die is additionally installed on the material pressing plate, and a discharging and positioning mechanism is additionally arranged on the stretching male die, so that it is guaranteed that materials are precisely positioned; meanwhile, the die can reduce the defect rate to the maximum degree, greatly improve production efficiency and overcome the defects existing in the prior art.
Description
Technical field
The utility model relates to the technical field of the drawing die of outline lower hem, specifically a kind of lower hem drawing die structure of metal sheet outline, particularly its frame for movement.
Background technology
Generally do similar products with stretching and flanging two molds, and product concentricity is poor, machine tool motion stroke requires large, and therefore production efficiency is not high, and defective products rate is higher.
Utility model content
The purpose of this utility model is to provide a kind of lower hem drawing die structure, stretching and lower hem can be arranged on one pair of mould, and a punching press completes.
To achieve these goals, the technical solution of the utility model is: a kind of lower hem drawing die structure, and it comprises upper bolster and die shoe, its feature comprises cope match-plate pattern at upper bolster, described cope match-plate pattern below is provided with stretching die, and the arranged outside of stretching die has flanging die; Die shoe comprises lower bolster, on described lower bolster, be provided with the stretching convex die matching with the die that stretches, the arranged outside of stretching convex die has the hem die matching with flanging die, the below of hem die is provided with holding pad, between described stretching die and flanging die, be provided with slidingtype die pad, between die pad and cope match-plate pattern, be provided with spring.According to preferred embodiment of the present utility model, the top of stretching convex die is provided with location-plate.Between holding pad and hem die, be connected by screw integrally, holding pad is connected with one end of push rod, and the other end of push rod is connected with the top board below being arranged on lower bolster through lower bolster.Described lower bolster bottom is also provided with mould pin.
The utility model adopts and installs flanging die and binder ejecting mechanism additional in stretching die periphery, what on holding pad, install hem die additional once completes stretching edge-folding mechanism, and in stretching convex die, set up discharging and detent mechanism, guarantee material accurate positioning, simultaneously, this mould can reduce defective products rate to greatest extent, greatly enhances productivity, and has overcome the shortcoming and defect existing in prior art.The utility model has the advantages that this mould can once complete lower hem and stretching two procedures, product size, concentricity and efficiency improve greatly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, a kind of lower hem drawing die structure, it comprises upper bolster and die shoe, it is characterized in that upper bolster comprises cope match-plate pattern 1, described cope match-plate pattern 1 below is provided with stretching die 6, and the arranged outside of stretching die 6 has flanging die 3, between described stretching die 6 and flanging die 3, is provided with slidingtype die pad 5, between slidingtype die pad 5 and cope match-plate pattern 1, be provided with spring 4, slidingtype die pad 5 moves up and down under the effect of spring 4; Die shoe comprises lower bolster 7, is provided with the stretching convex die 8 matching with the die 6 that stretches on described lower bolster 7, and the arranged outside of stretching convex die 8 has the hem die 9 matching with flanging die 3, and the below of hem die 9 is provided with holding pad 10.According to preferred embodiment of the present utility model, stretching die 6 is connected with cope match-plate pattern 1 by die backing plate 2.The top of stretching convex die 8 is provided with location-plate 11.Between holding pad 10 and hem die 9, link into an integrated entity by screw.In holding pad 10, be provided with guide pillar 12, be provided with guide pillar hole in lower bolster 7, one end of guide pillar 12 is connected with hem die 9, and the other end of guide pillar 12 stretches in the guide pillar hole in lower bolster, is slidably connected with its formation.Between lower bolster 7, holding pad 10 is connected with one end of push rod 13, the other end of push rod 13 is connected with the top board 14 that is arranged on lower bolster 7 belows through lower bolster 7, between push rod 13 and lower bolster 7, be slidably connected, promote holding pad 10 by top board 14 and move up and down as orientation along guide pillar 12 together with hem die 9.Described lower bolster 7 bottoms are also provided with mould pin 15.
To be placed on stretching convex die 8 tops for processing metal plate, located by location-plate 11, upper bolster and die shoe close up, coordinate and realize metal sheet stretching by stretching convex die 8 and stretching die 6, then promote top 14 plates, promote holding pad 10 by top board 14, thereby drive hem die 9 to move, coordinate by flanging die 3 and hem die 9 flanging of realizing metal sheet outline.After machining, separately, slidingtype die pad 5 ejects the metal sheet processing under the restoring force effect of spring for upper bolster and die shoe.Wherein holding pad can play reinforcement effect by conduplication side punch 9; Guide pillar 12 is played to fixation; Stock is played to picking-up stabilization.
