Abstract
The anti-tripping waste structure of circular die, comprise die, the center of described die is provided with manhole vertically, and the inwall of described manhole is provided with many straight raised lines for anti-tripping waste that are parallel to each other vertically, and described die inwall is with the gradient of monolateral inclination.The beneficial effects of the utility model are: solved the scraps-bounce of circular die in high speed blanking and scraps-bounce and caused that cutting edge of die bursts apart, the end falls in die life, the difficult problems such as production cost raising, thus effectively ensure to realize automatic stamping production line at a high speed.
Description
Technical field
The utility model relates to a kind of anti-tripping waste structure of circular die.
Background technology
The conventional circular die jump-scrap that solves high-speed electric expreess locomotive iron core multi-station progressive die is: find that there is jump-scrap in stamping-out time, mould is pulled down from lathe, cutting edge of die is carried out to slight abate or to the manual kerve of die inwall.Therefore, very time-consuming in the automated production of high speed stamping, when jump-scrap operating personnel are uncontrollable, could find out time often at finished product iron core, affect production efficiency and product cost.For this reason, just should consider and solve when the production mould as mould manufacturing company, our company is with advanced process equipment and the mentality of designing of innovation, by repeatedly engineer testing and improvement design repeatedly, the anti-tripping waste structure generation of the circular die of carbide alloy, thoroughly solve user very time-consuming in the automated production of high speed stamping, affected the passive situation of production efficiency, obtained users and approve of.
Summary of the invention
In the automated production of the utility model for current high speed stamping, jump-scrap occurring need to manually intervene, thereby affect the problem of production efficiency and product cost, proposed a kind of anti-tripping waste structure of avoiding the circular die that jump-scrap occurs in the automated production of high speed stamping.
The anti-tripping waste structure of circular die described in the utility model, comprise die, it is characterized in that: the center of described die is provided with manhole vertically, the inwall of described manhole is provided with many straight raised lines for anti-tripping waste that are parallel to each other vertically, and described die inwall is with the gradient of monolateral inclination.
The sidewall of described manhole is provided with vertically 2～4 and is parallel to each other and symmetrical point other straight raised line for anti-tripping waste.
The width of the straight raised line described in every is 0.50mm～1.0mm.
The gradient of described die inwall is monolateral 8 ' gradient.
The manhole diameter of phi D of described die is more than or equal to 6mm.
The anti-tripping waste structure of circular die described in the utility model: be the circular die by the silk thread cutting processing of being careful, in the time of the monolateral 8 ' gradient of processing die inwall, retain the straight trough of two to four width 0.50mm～1.0mm, as the straight raised line of anti-tripping waste.In continuous punching press, when circular waste material is constantly down extruded in die, straight raised line part waste material touches the straight wall of die always, has increased the frictional resistance of waste material and die wall, forces circular waste material to be firmly stuck in die, can not go up jumping.
The beneficial effects of the utility model are: solved the scraps-bounce of circular die in high speed blanking and scraps-bounce and caused that cutting edge of die bursts apart, the end falls in die life, the difficult problems such as production cost raising, thus effectively ensure to realize automatic stamping production line at a high speed.

Detailed description of the invention
Further illustrate the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
The anti-tripping waste structure of circular die described in the utility model, comprise die 1, the center of described die 1 is provided with manhole 11 vertically, the inwall of described manhole 11 is provided with many straight raised lines 12 for anti-tripping waste that are parallel to each other vertically, and described die inwall is with the gradient of monolateral inclination.
The sidewall of described manhole 11 is provided with vertically 2～4 and is parallel to each other and symmetrical point other straight raised line 12 for anti-tripping waste.
The width of the straight raised line 12 described in every is 0.50mm～1.0mm.
The gradient of described die 1 inwall is monolateral 8 ' gradient.
The manhole 11 diameter of phi D of described die 1 are more than or equal to 6mm.
The anti-tripping waste structure of circular die described in the utility model: be the circular die by the silk thread cutting processing of being careful, in the time of the monolateral 8 ' gradient of processing die inwall, retain the straight trough of two to four width 0.50mm～1.0mm, as the straight raised line of anti-tripping waste.In continuous punching press, when circular waste material 2 is constantly down extruded in die, straight raised line part waste material touches the straight wall of die always, has increased the frictional resistance of waste material and die wall, forces circular waste material to be firmly stuck in die, can not go up jumping.
Content described in this description embodiment is only enumerating of way of realization to utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also comprises that those skilled in the art conceive the equivalent technologies means that can expect according to the utility model.
