Description

Round type perforating die
Technical field
The present invention relates to stamping technology field, particularly relate to a kind of round type perforating die.
Background technology
Punching press, under normal temperature condition, utilize the diel be arranged on forcing press, pressure is applied to raw material, raw material are produced be separated or plastic deformation, thus obtaining a kind of pressure processing method of required part, perforating die is mould raw material being stamped out various nibs, and raw material can be sheet material, circular pipe, truncated cone-shaped tubing etc.As shown in Figure 4, be a kind of sectional view of round type product, it have two axial symmetry through holes, because batch is large, adopt perforating die to process in production, common perforating die is adding man-hour, round type level is put into perforating die, during upper/lower die pressing, two holes is gone out.But this perforating die is in process, located by round type by upper lower platen, not easily, if excessively loose during upper lower platen pressing, then round type location is inaccurate, is easy to cause two holes asymmetric in round type location; If upper and lower plates pressing tension, then round type is easy to distortion, has a strong impact on product quality, causes waste.
Summary of the invention
The problem to be solved in the present invention is, for the above-mentioned defect of prior art, provide a kind of round type accurate positioning convenient, two hole axial symmetry degree are high, and round type can not produce the round type perforating die of distortion.
Object of the present invention is achieved through the following technical solutions.Round type perforating die, comprise upper bolster, punch, die shoe, die, left and right sides symmetry below described upper bolster connects a depression bar, the lower end vertical connecting slide block of depression bar, two upright slide blocks side is in opposite directions inclined-plane, inclined-plane is from top to bottom to upright slide block dorsad laterally inclined, the top of die shoe connects die, the top of die is truncated cone-shaped, round platform is provided with the die through hole of the level run through from left to right, the left and right sides of die is respectively equipped with bearing, bearing is connected on die shoe, mobile link cross sliding clock on the upside of bearing, cross sliding clock connects piercing punch, piercing punch is horizontally disposed with, gripper shoe is provided with between die and bearing, piercing punch directs at die through hole through gripper shoe, spring is provided with between gripper shoe and cross sliding clock, cross sliding clock is inclined-plane away from the side of gripper shoe, this inclined-plane and the inclined-plane above it on upright slide block are same tilt degree.During work, the raw material of round type are inserted in die top, namely on round platform, utilize the tapering of round platform to locate, location is convenient, accurately, patrix is descending, upright slide block promotes cross sliding clock and moves to die direction, spring-compressed, piercing punch presses to the raw material of round type, stamps out through hole in its both sides; Patrix is up, and upright slide block moves, and cross sliding clock moves laterally under the effect of spring force, and piercing punch shifts out from product, and cross sliding clock is returned to original position, product can be taken out.In process, round type accurate positioning is convenient, and the axial symmetry degree of holes is high, and this mould does not have pressing plate to be pressed on round type, and round type does not exist the problem producing distortion, and product quality is high, avoids waste, reduces production cost.
As preferably, described cross sliding clock is that the side on inclined-plane is provided with take-up housing, and take-up housing is fixedly connected on the upside of bearing, and take-up housing is provided with the first U-shaped groove, and upright slide block is positioned at the first U-shaped groove, both matched in clearance.During patrix up-downgoing, upright slide block moves in the first U-shaped groove of take-up housing, take-up housing play the guiding role, improve the smoothness of upright slide block movement, to improve the standard the mobile smoothness of slide block, thus improve the Aligning degree of piercing punch and die through hole, make the axial symmetry Du Genggao of holes on round type.
As preferably, the upside of described bearing is provided with the second U-shaped groove, and cross sliding clock is arranged in the second U-shaped groove, both matched in clearance, and structure is simple, and cross sliding clock moves steadily.
As preferably, the lower surface of described upper bolster is fixedly connected with backing plate, and the lower surface of backing plate is fixedly connected with fixed head, and depression bar is fixedly connected on fixed head.
As preferably, the left and right sides of described fixed head lower surface is fixedly connected with guide pin bushing respectively, guide pin bushing is positioned at the outside of depression bar, the left and right sides of die shoe upper surface is fixedly connected with guide pillar respectively, guide pin bushing and guide pillar are corresponding up and down, the degree of accuracy of position when guide pin bushing guide pillar improves piercing punch punching, improves the symmetry of holes on round type further.
As preferably, the top of described upper bolster connects a die shank, and when upper bolster is arranged on forcing press, accurate positioning is convenient.
The invention has the beneficial effects as follows, in process, round type accurate positioning is convenient, the axial symmetry degree of holes is high, and this mould does not have pressing plate to be pressed on round type, there is not the problem producing distortion in round type, product quality is high, avoid waste, reduce production cost, easy to operate, die and punch Aligning degree high, not easily produce interference, upper bolster is accurately easy for installation.
