The beneficial effects of the utility model are: product one-shot forming, boosts productivity, and ensure Product Precision, save manufacturing cost, simplify mould structure.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: die shoe 1, unloading bolt 2, counterdie backing plate 3, punch-die fixed head 4, rubber 5, guide pillar 6, guide pin bushing 7, pin stop 8, punch retainer 9, upper die plate 10, soket head cap screw 11, upper bolster 12, rubber 13, die shank 14, beat bar 15, piercing punch 16, alignment pin 17, upper ejector pin 18, bending punch 19, blanking die 20, punch-die 21, stripper 22, alignment pin 23, soket head cap screw 24, lower push rod 25, cylindroid helical-coil compression spring 26.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of bracket blanking die, comprise upper die and lower die, described patrix comprises guide pin bushing 7, punch retainer 9, upper bolster 12, die shank 14, piercing punch 16, bending punch 19 and blanking die 20, guide pin bushing 7 is fixed on below upper bolster 12, die shank 14 is fixed on upper bolster 12, punch retainer 9 is positioned at below upper bolster 12, piercing punch 16 is fixed on punch retainer 9, bending punch 19 is provided with below punch retainer 9, blanking die 20 is provided with below bending punch 19, upper bolster 12, punch retainer 9 is fixedly connected with by pin 17 successively with blanking die 20, upper die plate 10 is provided with between upper bolster 12 and punch retainer 9, described counterdie comprises die shoe 1, counterdie backing plate 3, punch-die fixed head 4, punch-die 21 and stripper 22, punch-die 21 is fixed on punch-die fixed head 4, punch-die fixed head 4, counterdie backing plate 3 and stripper 22 are fixed on die shoe 1 successively, rubber 5 is provided with between counterdie backing plate 3 and stripper 22, stripper 22 is provided with pin stop 8, cylindroid helical-coil compression spring 26 is provided with in counterdie backing plate 3, guide pillar 6 one end is located in guide pin bushing 7, the other end is fixed on die shoe 1, described bending punch 19 matches with punch-die 21, upper ejector pin 18 one end connects bending punch 19, the other end connects lower push rod 25, lower push rod 25 is fixed on die shoe 1.
The course of work: when punch die is started working, upper die and lower die separate under forcing press effect, billot to be placed on stripper 22 and to be located by pin stop 8, when patrix declines under press ram effect, first bending punch 19 in patrix contacts billot, when continuing pressurization, bending punch 19 starts to carry out bending stamping-out to billot with punch-die 21, patrix continues to decline, be near completion bending after the outer rim of punch-die 21 and blanking die 20 act on and carry out blanking, enable rubber bear the effect of bending force simultaneously, patrix continues to decline, punching is carried out by the piercing punch be fixed on punch retainer 9 16 pairs of blanking parts, waste material is discharged from the material-dropping hole punch-die 21.When patrix gos up under press ram effect, make bar 15 to be moved down by upper ejector pin 18 and eject workpiece, be arranged on lower push rod 25 in die shoe 1 upwards jack-up under spring force simultaneously, take out goods, stripper 22 and billot return to again original position, prepare the stamping-out of lower one-stroke.
