Detailed description of the invention
A kind of multiple piercing mould as shown in Figure 2, comprise cope match-plate pattern 1, upper padding plate 2, for the punch 3 of stamping-out circular hole 100, multiple abnormal-shaped punchs 4, inner guiding post 7, the guide plate 8 for lead punch 3 and abnormal-shaped punch 4, the concave template 9 for support blank, lower bolster 11 and lower bolster 12 for the multiple irregularly-shaped hole of stamping-out 200, inner guiding post 7 is vertically arranged, upper end and the cope match-plate pattern 1 of this inner guiding post 7 are vertically slidably matched, lower end and the guide plate 8 of this inner guiding post 7 are vertically slidably matched, and the bottom surface of guide plate 8 is relative with the end face of concave template 9; Upper padding plate 2 is fixed on the bottom surface of cope match-plate pattern 1, and each abnormal-shaped punch 4 is around the axis axial symmetry distribution of punch 3, and upper padding plate 2 is all fixed in the upper end of punch 3 and the upper end of each abnormal-shaped punch 4; Guide plate 8 and concave template 9 are all run through in the lower end of punch 3 and the lower end of each abnormal-shaped punch 4, and are all slidably matched with guide plate 8 and concave template 9; Concave template 9 is fixed on the end face of lower bolster 11, and lower bolster 11 is fixed on the end face of lower bolster 12, and lower bolster 12 has the cavity 121 for blanking, the corresponding punch 3 in position of this cavity 121 and each abnormal-shaped punch 4.
For strengthening the firm fixed effect to abnormal-shaped punch 4, to promote the degree of stability of stamping-out further, the multiple piercing mould of this example also comprises retainer plate 5, compacting ring 6 and securing member, retainer plate 5 is fixedly set in the external peripheral surface of each abnormal-shaped punch 4, and support is in compacting ring 6 end face, one end of securing member is connected with cope match-plate pattern 1, the other end of securing member is connected with compacting ring 6 through after retainer plate 5, retainer plate 5 top is depressed into the bottom surface of upper padding plate 2 by compacting ring 6 through securing member, for being fastened and fixed retainer plate 5, thus make retainer plate 5 can fixedly secure abnormal-shaped punch 4, and then abnormal-shaped punch 4 is firmly fixed with the relative position of punch 3.And be strengthen fixing abnormal-shaped punch 4 further, the medial surface of retainer plate 5 is extended with annular pin 51, and this annular pin 51 inserts in each abnormal-shaped punch 4, and which can prevent abnormal-shaped punch 4 from misplacing, and is beneficial to and reaches higher punching precision.
Particularly, the securing member of this example comprises alignment pin 13 and screw 14, alignment pin 13 runs through cope match-plate pattern 1, upper padding plate 2, retainer plate 5 and compacting ring 6 successively, and the head of screw 14 is limited in cope match-plate pattern 1, and the screw rod of screw 14 passes after upper padding plate 2, retainer plate 5 and compacting ring 6 threaded engagement successively.
For promoting punching precision further, lower bolster 12 being also fixed with blank location-plate 10, for positioning blank, preventing blank from arbitrarily moving and causing stamping-out to be forbidden.
Punch 3 and abnormal-shaped punch 4 retainer plate 5 are fixed, and compacted plate 6 compresses under the effect of securing member; Inner guiding post 7 upper end and cope match-plate pattern 1 precision are slided and are joined, and inner guiding post 7 lower end and guide plate 8 precision are slided and joined; Punch 3, abnormal-shaped punch 4 are joined with guide plate 8 precision is sliding, vertical steadily descending when ensureing relative accuracy and the stamping-out of guide plate 8 and cope match-plate pattern 1; Punch 3 and abnormal-shaped punch 4 are joined with guide plate 8 precision is sliding, when ensureing stamping-out, punch 3 is vertical with abnormal-shaped punch 4 stablize descending.Punch 3, abnormal-shaped punch 4 adopt closely spaced blade clearance, monolateral gap about 0.03 ~ 0.05mm with concave template 9.
During work: blank is delivered to and specified station correct position, cope match-plate pattern 1 is descending, guide plate 8 and cope match-plate pattern 1 link, compress blank also simultaneously to punch 3 and abnormal-shaped punch 4 accurate guide effects, cope match-plate pattern 1 comes downwards to bottom dead centre, and blank is worn in punch 3 and the first backlash of abnormal-shaped punch 4, completes and goes out circular hole 100 and multiple irregularly-shaped hole 200 simultaneously, the finished product that this example is gone out is 48 irregularly-shaped holes 200, around the periphery circle distribution (as shown in Figure 1) of circular hole 100; Cope match-plate pattern 1 is up, and blank waste material is released from punch 3 and abnormal-shaped punch 4 by guide plate 8; Waste material drops through cavity 121.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
