The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of thin plate polyurethane rubber fine-edge blanking mould is used for the punching press of metallic stamping pieces, and it is made up of upper die and lower die two parts, and upper die and lower die are slidingly connected by guide pillar 22 and guide pin bushing 5.
Patrix is made of upper bolster 7, backing plate 8, punch retainer 9, die shank 10, punch 11, hyperbola polyurethane rubber 12, pressing plate 13, guide pin bushing 5, die 6.Die shank 10 and upper bolster 7 adopt and are threaded, adopt interference fit between punch 11 and the punch retainer 9, pressing plate 13 can slide in punch 11 and die 6, upper bolster 7, backing plate 8, punch retainer 9, die 6 connect by four screws, two straight pin location, hyperbola polyurethane rubber 12 compresses in punching course, and it is smart in needed casting die power that pressing plate 13 is produced, to guarantee that pressing is towards part.
Counterdie is made up of discharging screw 4, contour cover 3, little guide pin bushing 2, punch-die 14, gear ring pressing plate 15, polyurethane rubber 16, push rod 17, fixed head 18, hassock plate 19, top board 21, gripper shoe 20, die shoe 1 and guide pillar 22 etc.Adopt interference fit to connect between punch-die 14 and the fixed head 18, push rod 17 can slide in punch-die 14, rely on the hyperbola polyurethane rubber to produce kicking force, gear ring pressing plate 15 can slide in punch-die 14, gear ring pressing plate 15 and discharging screw 4 adopt and are threaded, contour cover 3 and discharging screw 4, hassock plate 19, it between the die shoe 1 matched in clearance, cooperate for H6/H5 between contour cover 3 and the little guide pin bushing 2, connect for interference between little guide pin bushing 2 and the fixed head 18, die shoe 1 and top board 21, pass through two nut checks between the gripper shoe 20, the support that guarantees the hyperbola polyurethane rubber is steady, fixed head 18, connect two straight pin location between hassock plate 19 and die shoe 1 three by four screws.In the mold process, gear ring pressing plate 15 relies on the hyperbola polyurethane rubbers that pressure-pad-force is provided under patrix enters, and push rod 17 relies on the hyperbola polyurethane rubbers that ejecting force is provided.After the upper and lower mould assembling, cooperate between guide pillar 22 and the guide pin bushing 5 to be H6/h5, to guarantee the uniformity and the cross section quality of die clearance in the punching course.
Sheet metal is placed on the gear ring pressing plate 15, rely on the finger setting of shelves material, patrix is descending, and the power that gear ring pressing plate 15 relies on the hyperbola polyurethane rubber to provide at first compresses plate, then, the power that pressing plate 13 and push rod 17 rely on the hyperbola polyurethane rubber to provide respectively produces pressure-plate-force and ejecting force, tightly plate is compressed, patrix continuation subsequently is descending, and punch-die 14 enters die 6 under pressure, punch 11 also enters in the punch-die 14 under the pressure simultaneously, finishes the stamping-out process.Patrix is up subsequently, and the hyperbola polyurethane rubber elasticity that relies on behind pressing plate 13 and the push rod 17 is recovered, and will eject from mould towards part and waste material, and whole punching course finishes.This die feature: institute is towards product cross section quality height, no burr phenomena, and mould structure is simple, and is easily manufactured, with low cost, and investment cost is little, highly versatile.
