Abstract
The utility model discloses a precise stamping die with a gear ring pressing plate and relates to a stamping die. The precise stamping die with the gear ring pressing plate comprises an upper die base, a lower die base and a die handle. A discharging plate is connected with the side wall of a protruding die in a sleeved mode. The discharging plate is movably connected with upper die base through discharging bolts. Discharging springs are connected with the discharging bolts in a sleeved mode. The precise stamping die with the gear ring pressing plate further comprises the gear ring pressing plate which is a ring-shaped plate. A ring-shaped groove is formed in the lower surface of the discharging plate, wherein the ring-shaped groove fits in with the gear ring pressing plate. The gear ring pressing plate is fixedly connected with the inner side of the ring-shaped groove and fits in with the protruding die gap. The lower surface of the gear ring pressing plate is provided with a gear-shaped protrusion. When the discharging spring is not in a compression state, the lower surface of the gear-shaped protrusion is lower than that of the discharging plate and the protruding die. A top plate is arranged in a protruding die hole of the protruding die. The lower end of the top plate is fixedly connected with an ejector rod. The lower end of the ejector rod is connected with a rubber pad. The precise stamping die with the gear ring pressing plate has the advantages of being capable of increasing the pressure to a material belt in stamping, and enabling the material belt to be in a three-directional compressive stress state, preventing the material belt from bending and improving accuracy of product and section quality.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of precise punching mould with the gear ring pressing plate.
Background technology
Stamping die is a kind of industrial production common equipment, it can carry out the processing and forming such as punching and blanking, existing stamping die is when the thin material of punching press, strip is in free state, and when punching or blanking, strip is easy to wrinkling, affect the precision of product, increased percent defective, even adopt stripper spring-loaded stripping and push piece, also because can not prevent that the stopping materials strip vault is curved not to the pressure of strip.When using in addition existing stamping die punching press, strip only is subject to the pressure of punch, and the shearing splitting phenomenon can appear in the strip at the cutting edge place, and the product section only has the euphotic belt about 1/3, and all the other are coarse fracture belt, and cross section quality is poor.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of precise punching mould with the gear ring pressing plate, to the pressure of strip, allows strip be in the state of three-dimensional compressive stress in the time of can increasing punching press, anti-stopping materials strip vault is curved, improves precision and the cross section quality of product.
The technical solution of the utility model is: a kind of precise punching mould with the gear ring pressing plate, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with punch, the die shoe upper surface is provided with die, the punch sidewall sheath is connected to stripper, stripper is flexibly connected by unloading bolt and upper bolster, be socketed with the discharging spring on the unloading bolt, also comprise the gear ring pressing plate, the gear ring pressing plate is the annular plate, the stripper lower surface has the annular groove with gear ring pressing plate coupling, the gear ring pressing plate be fixedly connected in the annular groove and with the punch matched in clearance, the lower surface of gear ring pressing plate is provided with detent projection, and when the discharging spring was in uncompressed state, the lower surface of detent projection was lower than the lower surface of stripper and punch; Be provided with top board in the die hole of die, the top board lower end is fixedly connected with push rod, and the push rod lower end is connected with rubber blanket.
As preferably, described punch adopts GCr15 to make, and is provided with backing plate between punch and the upper bolster, and backing plate adopts 45 steel to make, and punch is fixedly connected on the backing plate lower surface by punch retainer.
As preferably, described die adopts carbide alloy to make, and die hole is up-small and down-big shoulder hole, and when rubber blanket was in uncompressed state, the upper surface of top board was higher than the upper surface of die.
As preferably, the upper bolster lower surface is provided with guide pin bushing, and the die shoe upper surface is provided with the guide pillar that cooperates with guide pin bushing, and described guide pin bushing and guide pillar adopt 20 steel to make, and is provided with ball in the gap that guide pin bushing and guide pillar cooperate.
The beneficial effects of the utility model are: gear ring pressing plate of the present utility model can strengthen the pressure to strip when punching press, can not produce the elasticity vault and bend up wrinkle, has improved the precision of product.Strip is in the stress state of three dimension stress during punching press under the effect of gear ring pressing plate, top board, punch and die, only produces plasticity and shears the shearing splitting phenomenon in the time of can not general stamping-out occurring.Whole stamping-out section all is the euphotic belt of shearing, and cross section quality is good.The ball that arranges in the gap that guide pin bushing and guide pillar cooperate can improve the positioning accuracy of upper bolster and die shoe, has further improved the precision of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of precise punching mould with the gear ring pressing plate, comprise upper bolster 8, die shoe 1 and die shank 9, in the present embodiment, as preferably, upper bolster 8 and die shoe 1 adopt the Q235 steel to make good combination property, long service life.Die shank 9 presses fit in the upper bolster 8, and fixes by screw.Upper bolster 8 lower surfaces are provided with punch 5, die shoe 1 upper surface is provided with die 2, punch 5 sidewall sheath are connected to stripper 4, stripper 4 is flexibly connected by unloading bolt 10 and upper bolster 8, be socketed with discharging spring 6 on the unloading bolt 10, also comprise gear ring pressing plate 12, gear ring pressing plate 12 is the annular plate, stripper 4 lower surfaces have the annular groove with gear ring pressing plate 12 couplings, gear ring pressing plate 12 be fixedly connected in the annular groove and with punch 5 matched in clearance, the lower surface of gear ring pressing plate 12 is provided with detent projection, and when discharging spring 6 was in uncompressed state, the lower surface of detent projection was lower than the lower surface of stripper 4 and punch 5; Be provided with top board 3 in the die hole of die 2, top board 3 lower ends are fixedly connected with push rod 15, and push rod 15 lower ends are connected with rubber blanket.
