Description
Technical field
The utility model relates to stamping technology field, particularly relates to a kind of flanged cask mould bottom surface macropore punch die.
Background technology
Punching press on punch press, makes metal or non-metal sheet generation separation or distortion with punch die and obtains the processing method of product.As shown in Figure 3 to Figure 4, be a flanged cylindrical member, have a larger circular hole in its bottom surface, the diameter of macropore is almost close to the diameter of bottom surface, processing method is the basic configuration first adopting metal sheet stamping to go out flanged cask mould, then goes out macropore on its bottom surface.When rushing the macropore of bottom surface, because the diameter of macropore is almost close to the diameter of bottom surface, if die adopts conventional structure, the wall thickness of die will be very thin, make the intensity of die not enough, die is easily out of shape, and cause product product quality to reduce, and die easily damages, service life is short, production cost is high, and need frequent maintain and replace die, production efficiency is low.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, provide a kind of flanged cask mould bottom surface macropore punch die, strength of concave mould is high, not yielding, product product quality is high, not fragile, long service life, reduces production cost, improves production efficiency.
The purpose of this utility model is achieved through the following technical solutions.Flanged cask mould bottom surface macropore punch die, comprise upper bolster, convex mould pad, fixed head, punch, die shoe, die, convex mould pad is fixedly connected on upper bolster lower surface, fixed head is fixedly connected on convex mould pad lower surface, punch is fixedly connected on fixed head, die is arranged on the upside of die shoe, the downside of described fixed head is provided with elastic connection structure, the downside of elastic connection structure is provided with holding pad, holding pad comprises the boss of its downside, punch is through elastic connection structure and holding pad, upper bolster is provided with some through holes, a screw is provided with in each through hole, screw is successively through upper bolster, convex mould pad, fixed head, elastic connection structure, the lower end of screw is fixedly connected on holding pad, die shoe upper surface is fixedly connected with die backing plate, die backing plate upper surface is fixedly connected with die.Adopt this punch die, the cylindrical portion of product blank is put into die hole inner position, and patrix is descending, and the boss of holding pad and the lower end of punch are pressed in the bottom surface of product, and patrix continues descending, and the macropore on bottom surface gone out by punch, and patrix is up, takes out product.Owing to being locate with the die hole of die, it is thicker that the wall thickness of die can make, so the intensity of die is very high, not yielding, long service life, the quality of product is high.
As preferably, described elastic connection structure is block rubber, and structure is simple, and easy for installation, elasticity is high, and bounce is strong, and when patrix is up, discharging is fast.
As preferably, described die is provided with some installing holes, is provided with an elastic support structure in each installing hole, and elastic support structure comprises a spring, and the supporting pin be positioned on the upside of spring, when patrix is descending, the boss of punch and holding pad is pressed on the bottom surface of product, and spring is compressed, when patrix is up, springback, by product jack-up, so take off product from die very easily.
As preferably, the upside of described upper bolster is fixedly connected with a die shank, simple and compact for structure, and when patrix is loaded forcing press, location and installation is convenient.
The beneficial effects of the utility model are, strength of concave mould is high, not yielding, and product product quality is high, not fragile, and long service life, reduces production cost, improves production efficiency, simple and compact for structure, easy for installation.
