Abstract
The invention relates to a male die, in particular to a male die with a fixing device. The male die with the fixing device solves the problem that an existing male die fixing device needs to disassemble the male die when replacing the same, so that time and labor are wasted. The male die with the fixing device comprises a male die body, a male die fixing plate and a backing plate which is fixed on the upper surface of the male die fixing plate; a male die installation hole which is in trace interference fitness with the male die body is arranged on the male die fixing plate; a groove with one end being communicated with the male die installation hole is arranged on the upper surface of the male die fixing plate; a threaded hole which is communicated with the other end of the male die is arranged on the male die fixing plate; a jackscrew which is matched with the threaded hole is arranged in the threaded hole; one end of the male die body which is arranged in the male die installation hole is provided with a circular groove; and a steel bead which is inlaid in the circular groove is arranged in the groove. The invention has a simple structure and an ingenious design, and can be widely applied to all male dies.
Description
Technical field
The present invention relates to punch, be specially a kind of punch with fixture.
Background technology
In recent years, in the industrial enterprise developed commodity economy, blanking die is widely used.The backing plate 3 that existing blanking die convex mould fixture comprises punch retainer 2 and is fixed in punch retainer 2 upper surfaces, have the punch installing hole on punch retainer 2, punch body 1 is placed in the punch installing hole and top contacts with backing plate 3, and cast bonding fixing (as shown in Figure 1), the fixing modes such as (as shown in Figure 2) of pin lifting are arranged during solid punch.Wherein cast bonding fixed form adopts the low-melting alloy cast fixing mostly, low-melting alloy cast fixedly refers to low-melting alloy 7(is commonly called as to expanded metal) be cast between the punch retainer 2 and punch body 1 in the punch installing hole after thawing, the principle expanded while utilizing low-melting alloy cooling tightly is linked together punch body 1 and punch retainer 2, but the shortcoming of the fixing cast of low-melting alloy is: need to be by mold disintegration when (1) changes the punch body; (2) while assembling punch, need to, to punch body and punch retainer preheating, easily produce and add thermal deformation; (3) expend more valuable bismuth metal; (4) because low-melting alloy intensity is not too high, thus can only stamping-out two millimeters with lower steel plate.And pin lifting fixed form is by punch body 1 and the micro-interference fit of punch retainer 2, punch body 1 to be fixed in the punch installing hole, by pin 8, thereby punch body 1 and punch retainer 2 are fixed together and prevent that punch body 1 is up and down in the punch installing hole, but the shortcoming of pin lifting fixed form is also must, by mold disintegration, to waste time and energy while changing punch.
Summary of the invention
The present invention, in order to solve when existing punch fixture is changed punch the problem that mold disintegration need be wasted time and energy, provides a kind of punch with fixture.
The present invention adopts following technical scheme to realize: a kind of punch with fixture, comprise punch body, punch retainer and the backing plate that is fixed in the punch retainer upper surface, have the punch installing hole with punch body trace interference fit on punch retainer, the upper surface of punch retainer has the groove that an end communicates with the punch installing hole; Have the screwed hole communicated with the groove other end on punch retainer; Be provided with the jackscrew cooperatively interacted with screwed hole in screwed hole; The end that is positioned at the punch installing hole of punch body has cannelure, is provided with the steel ball embedded in cannelure in groove.
During assembling, at first fixed head and backing plate are fixed together, then the punch body is knocked on punch retainer and punch installing hole punch body trace interference fit, steel ball is put into to the groove of punch body upper surface by screwed hole simultaneously, then jackscrew is screwed in screwed hole, tightening jackscrew makes steel ball tightly be embedded in the cannelure that is positioned at punch installing hole inner end of punch body, the top of punch body and backing plate close contact, so just be fixed on the punch body in the punch installing hole tightly.While changing the punch body, the jackscrew in the screwed hole of only need back-outing, take out the steel ball in groove, extracts the punch body and get final product from the punch installing hole, time saving and energy saving and saved resource.
The present invention is simple in structure, it is ingenious to design, and solved the problem that mold disintegration need be wasted time and energy while having the punch fixture to change punch, can be widely used in all punch.

The specific embodiment
A kind of punch with fixture, comprise punch body 1, punch retainer 2 and the backing plate 3 that is fixed in punch retainer 2 upper surfaces, have the punch installing hole with punch body 1 micro-interference fit on punch retainer 2, the upper surface of punch retainer 2 has the groove 6 that an end communicates with the punch installing hole; Have the screwed hole communicated with groove 6 other ends on punch retainer 2; Be provided with the jackscrew 4 cooperatively interacted with screwed hole in screwed hole; The end that is positioned at the punch installing hole of punch body 1 has cannelure, is provided with the steel ball 5 embedded in cannelure in groove.
Claims (1)
1. the punch with fixture, comprise punch body (1), punch retainer (2) and the backing plate (3) that is fixed in punch retainer (2) upper surface, have the punch installing hole with the micro-interference fit of punch body (1) on punch retainer (2), it is characterized in that: the upper surface of punch retainer (2) has the groove (6) that an end communicates with the punch installing hole; Have the screwed hole communicated with groove (6) other end on punch retainer (2); Be provided with the jackscrew (4) cooperatively interacted with screwed hole in screwed hole; The end that is positioned at the punch installing hole of punch body (1) has cannelure, is provided with the steel ball (5) embedded in cannelure in groove.
