Description
Technical field
The utility model relates to mould applications, especially a kind of concave-convex mold for preventing scrap-bounce.
Background technique
Blanking die is that indispensable technological equipment is punched down during Dies ' Blanking in punching production
Rebound phenomenon often occurs for waste material, this phenomenon easily causes defect rate to rise, or even mold is caused to damage；Typically result in waste material
The reason of rebound is that the magnetic force and greasy dirt at punch-pin cutting edge adsorb, and the roughness of cavity plate inner wall surface is too small；Waste material in order to prevent
Rebound is generallyd use to punch-pin cutting edge demagnetization decontamination, increases punch-pin length, periodically increases the side such as roughness of cavity plate inner wall surface
Method, although operating more time-consuming, maintenance cost is higher to preventing the waste material from having certain effect.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of concave-convex mold for preventing scrap-bounce.
The purpose of this utility model is achieved through the following technical solutions: a kind of concave-convex mold preventing scrap-bounce, it is wrapped
Punch-pin and cavity plate are included, the top of cavity plate is arranged in the punch-pin, and punch-pin includes punching sword, and the cutting edge for being punched sword is equipped with dovetail groove,
The top of the cavity plate is equipped with cutting edge of die, is equipped with waste material anti-hopping in cutting edge of die, and the cavity plate further includes waste material type chamber, is given up
Material type chamber is located at the lower section of cutting edge of die.
Preferably, the dovetail groove is located at the middle part of punching sword and the depth of dovetail groove is less than the thickness of punching material.
Preferably, the dovetail groove is circular groove or the v-depression with chamfering.
Preferably, the waste material anti-hopping has two and is located at the two sides of cutting edge of die, and two waste material anti-hoppings are equal
It is obliquely installed and tilt angle is opposite.
Preferably, the side of the waste material type chamber is inclined outwardly.
The utility model has the advantage that the utility model structure is simple, easy to operate, and the waste material after punching is stuck in
In anti-hopping, waste material is effectively prevent to jump out cavity plate, avoids product quality impacted, while mold being prevented to be destroyed.

Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As shown in figures 1-4, a kind of concave-convex mold preventing scrap-bounce, it includes punch-pin 1 and cavity plate 2, and the punch-pin 1 is set
It sets in the top of cavity plate 2, punch-pin 1 includes punching sword 3, and the cutting edge of punching sword 3 is equipped with dovetail groove 4, and the top of the cavity plate 2 is equipped with
Cutting edge of die 5, cutting edge of die 5 is interior to be equipped with waste material anti-hopping 6, and the cavity plate 2 further includes waste material type chamber 7, and waste material type chamber 7 is located at recessed
The lower section of mould edge mouth 5.
Preferably, the dovetail groove 4 is located at the middle part of punching sword 3 and the depth of dovetail groove 4 is less than the thickness of punching material.
Preferably, the dovetail groove 4 is circular groove or the v-depression with chamfering.
Preferably, the waste material anti-hopping 6 has two and is located at the two sides of cutting edge of die 5, two waste material anti-hoppings 6
It is obliquely installed and tilt angle is on the contrary, waste material is stuck in waste material anti-hopping 6 after being punched by punch-pin 1.
Preferably, the side of the waste material type chamber 7 is inclined outwardly.
The course of work of the utility model is as follows: workpiece being placed on cavity plate 2, is turned on the switch, press formed punch drives convex
Mould 1 moves downward, and after punching sword 3 is punched out waste material on workpiece with cutting edge of die 5, punch-pin 1 continues to decline a distance, will give up
Material is stuck in waste material anti-hopping 6, and by being continuously punched, the waste material of 2 inner cavity of cavity plate accumulation is more and more, is finally generated at first
Waste material can be detached from cutting edge of die 5 and enter waste material type chamber 7, and the tapered structure of waste material type chamber 7 prevents the waste material of 7 bottom of waste material type chamber
It knock-ons cavity plate 2 out.
The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model
System.Anyone skilled in the art, in the case where not departing from technical solutions of the utility model ambit, all using above-mentioned
The technology contents make many possible changes and modifications to technical solutions of the utility model, or be revised as equivalent variations etc.
Imitate embodiment.Therefore, all contents without departing from technical solutions of the utility model, the technology according to the utility model is to the above reality
Any change modification, equivalent variations and modification that example is made are applied, the protection scope of the technical program is belonged to.
