The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 4, the mould that utilizes concavo-convex method wire cutting technology that the utility model provides, comprise stacked from the bottom to top lower bolster 1, bottom plate 2, punch 3, stripper 4, ejector 5, die 6, upper mounted plate 7, cope match-plate pattern 8, and the screw, pin, spring and the guide pillar 9 that are used for connection.
As shown in Figure 5, die 6 and stripper 4 are " returning " font of central hollow out, and the rectangular slab that its centre cuts out is respectively as punch 3 and ejector 5.
Ejector 5 is formed by same line of material cutting processing with stripper 4.
As shown in Figure 6, the interlude on ejector 5 four limits inwardly forms respectively " recessed " font, and the corresponding position, four limits of stripper 4 central hollow outs forms " protruding " font.Distance between the protrusion place on stripper 4 relative both sides can satisfy the requirement of these stripper 4 working sizes.The distance of ejector 5 between adjacent two jiaos can satisfy the requirement of these ejector 5 working sizes, and namely the four limit length of sides of ejector 5 satisfy the dimensional requirement of this ejector.The working size of embodiment shown in Fig. 6 is: stripper 4 is 29.96mm * 49.96mm, and ejector 5 is 29.98mm * 49.98mm.
Ejector 5 is arranged at the central hollow part of die 6, stripper 4 be placed on punch 3 around.
Ejector 5 and cope match-plate pattern 8 usefulness run through contour screw 10 and the first spring 11 that upper mounted plate 7 is connected with die and are connected.
Stripper 4 is connected with unloading bolt 12 and the second spring 13 that lower bolster 1 usefulness runs through bottom plate 2.
Cope match-plate pattern 8, upper mounted plate 7 and die 6 are fixed by pin, and are connected by screw.
Bottom plate 2, lower bolster 1 and punch 3 are fixed by pin, and are connected by screw.
Cope match-plate pattern 8, upper mounted plate 7, die 6 and ejector 5 form the first half of moulds; Stripper 4, punch 3, bottom plate 2 and lower bolster 1 form the latter half of mould.
The same side that cope match-plate pattern 8 is connected with lower bolster connects by guide pillar 9.Mould the first half and the latter half can be opened from a side relative with guide pillar 9.During work, the first half and the latter half of mould are opened, and put into workpiece to be processed 14, it is placed between ejector 5 and the punch 3, then close die, at this moment, die 6 and punch 3 cut off materials, because the effect of spring, move on ejector 5 pressurizeds, stripper 4 pressurizeds move down, after the first half of mould and the latter half are opened again, spring makes ejector 5 and stripper 4 to mobile in the other direction, just can take out the workpiece that punching press is finished.
The mould that utilizes concavo-convex method wire cutting technology that the utility model provides is compound die, the stripper 4 that employing is suppressed, with pilot pin and Progressive Dies and continuous forming die in, stripper 4 and ejector 5 not only play the discharging effect and double as guiding usefulness, but also play the binder effect.So guarantee the gap between punch 3 and stripper 4, the ejector 5.
If with general line patterning method, two plates that cut off do not meet the size of die drawing defined, thereby do not reach the effect that stripper 4 and 5 pairs of a whole set of moulds of ejector play.So need to make respectively stripper 4 and ejector 5 with two blocks of mold materials plates with general wire cutting technology, need equally the line cutting wire time twice.In order to save man-hour and material cost, take concavo-convex patterning method, only make stripper 4 and ejector 5 with a block of material.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
