Abstract
The invention relates to a cold punching device applied to an integrated process of hole-flanging and chamfering. The cold punching device comprises a convex die and a concave die and is characterized in that the convex die is rod-shaped; a punching part used for punching to form a flanged hole is arranged at one end of the convex die; a first cant is formed between the root of the punching part and the convex die; an inner cylindrical cavity is formed in the concave die; a step hole is formed in the upper end of the inner cavity; the diameter of the step hole is matched with the outer diameter of the flanged edge formed after punching the flanged hole; a second cant is formed in the root of the step hole; the diameter of the punching part is gradually increased from the top to the bottom and is smaller than that of the convex die; the second cant is inclined from the root of the step hole to the inner cavity of the concave die. The production can be implemented by applying the device to an appropriate part of the die; the processes are reduced; the time is saved; the cost is reduced; meanwhile, the quality of the product is improved; the omitted processes caused by circulating a plurality of processes are avoided; the efficiency is significantly improved.
Description
Technical field
The present invention relates to a kind of cold punching die, especially a kind of cold stamping device for hole flanging chamfering integrated technique, belongs to cold punching die technical field.
Background technology
The hole flanging of Automobile Parts, head chamfering type are a lot, and traditional method is to the pre-hole of panel beating subpunch, chamfering, and then hole flanging, finally machining product end, chamfering, operation is various, easily leaks operation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of cold stamping device for hole flanging chamfering integrated technique is provided, the integrated technique of hole flanging chamfering can be realized, decrease operation, save the time, reduced cost; Improve product quality simultaneously, avoid, because multiple operation circulation causes leakage operation, raising the efficiency.
According to technical scheme provided by the invention, the described cold stamping device for hole flanging chamfering integrated technique, comprises punch and die, it is characterized in that: described punch is bar-shaped, one end of punch is the punching portion forming hole flanging for punching, forms the first inclined-plane between the root in punching portion and punch; Be provided with cylindrical cavity in described die, inner chamber upper end forms stepped hole, the diameter of this stepped hole with rush hole flanging after the external diameter of flange that formed match; The second inclined-plane is formed at the root of described stepped hole.
Further, the diameter in described punching portion from bottom to top increases gradually.
Further, the diameter in described punching portion is less than the diameter of punch.
Further, described second inclined-plane by the root of stepped hole to cavity dumping in die.
Cold stamping device for hole flanging chamfering integrated technique of the present invention, adopt integrated design, adopt hole flanging punch and the die according to shape of product copying, application of installation of the present invention can be produced in mould suitable position, decrease operation, save the time, reduce cost, improve the quality of products simultaneously, avoid, because multiple operation circulation causes leakage operation, significantly improving efficiency.
