Abstract
A simple fine blanking die relates to the field of stamping equipment. A die shank is arranged on an upper die seat; guide sleeves and guide posts are arranged between the upper die seat and a lower die seat, and are movably connected; a male die is arranged at the lower end of the upper die seat; a backing plate is arranged between the male die and the upper die seat; an unloading plate is arranged on the lower side of the male die; the lower end of the unloading plate is provided with an annular opening; a gear ring pressure plate is arranged in the annular opening; a top plate is arranged in the middle of a female die; three ejector rods are arranged at the lower end of the top plate; the female die is fixed at the upper end of the lower die seat through a left bolt and a right bolt; two unloading bolts are arranged among the upper die seat, the backing plate and the unloading plate; and disk springs are arranged on the unloading bolts. The simple fine blanking die can overcome defects in the prior art, enhances anti-pressure ability, prevents the deviation of a die, and ensures the stamping precision of the die.
Description
Technical field:
The utility model relates to a kind of diel, is specifically related to a kind of Simple Fine Blanking.
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 the percent defective of product, 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 of 1/3 left and right, and all the other are coarse fracture belt, and cross section quality is poor.
The patent No. 201120025855.1 discloses a kind of Simple Fine Blanking, when it can increase punching press to the pressure of strip, allow strip be in the state of three-dimensional compressive stress, can prevent that the stopping materials strip vault is curved, improve precision and the cross section quality of product, but the lower end of the top board that arranges in its die only is provided with two push rods, the pressure-bearing dynamics is inadequate, can only bear the pressure to thin material, be easy to cause push rod to fracture for thick material; The junction of its punch and patrix, die and bed die all only has a screw in addition, affects its steadiness, and mould is easy to occur deviation phenomenon in punching course, thereby affects its punching precision.
The utility model content:
The purpose of this utility model is to provide a kind of Simple Fine Blanking, and it can overcome the drawback of prior art, strengthens its anti-pressure ability, prevents mould generation deviation phenomenon, has guaranteed the punching precision of mould.
in order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises upper bolster 1, die shoe 2, die shank 3, punch 4, die 5, guide pin bushing 6, guide pillar 7, top board 8, backing plate 9, stripper 10, gear ring pressing plate 11, be provided with die shank 3 on upper bolster 1, be provided with guide pin bushing 6 and guide pillar 7 between upper bolster 1 and die shoe 2, guide pillar 7 is flexibly connected with guide pin bushing 6, the lower end of upper bolster 1 is provided with punch 4, be provided with backing plate 9 between punch 4 and upper bolster 1, stripper 10 is arranged on the downside of punch 4, the lower end of stripper 10 is provided with annular opening, gear ring pressing plate 11 is arranged in annular opening, be provided with top board 8 in the middle of die 5, the lower end of top board 8 is provided with three push rods 15, die 5 is fixed on die shoe 2 upper ends by two of left and right screw 14.
Be provided with two unloading bolts 12 between described upper bolster 1, backing plate 9 and stripper 10, be provided with disc spring 13 on unloading bolt 12.
The utility model is provided with three push rods 15 in the lower end of top board 8, increased the anti-pressure ability of mould, be provided with in addition two unloading bolts 12 between upper bolster 1, backing plate 9 and stripper 10, die 5 is connected with two screws of employing of bed die seat 2, greatly strengthened the steadiness of its structure, prevent that mould from deviation phenomenon occuring in punching course, thereby guarantee its punching precision.
The utility model can overcome the drawback of prior art, strengthens its anti-pressure ability, prevents mould generation deviation phenomenon, has guaranteed the punching precision of mould.
