Abstract
The utility model relates to a cold stamping device that is used for integrative technology of hole flanging chamfer, including terrace die and die, characterized by: the terrace die is bar -shapedly, and the one end of terrace die forms the portion of punching a hole of hole flanging for being used for punching a hole, forms first inclined plane between the root of the portion of punching a hole and the terrace die, be equipped with cylindrical inner chamber in the die, the inner chamber upper end forms the step hole, and the diameter and the turn down rims external diameter that forms behind the hole flanging in this step hole cooperate, the root in step hole forms the second inclined plane. The diameter of the portion of punching a hole is from bottom to top crescent. The diameter of the portion of punching a hole is less than the diameter of terrace die. The second inclined plane is by the inner chamber slope to the die of the root in step hole. Will the device is applied to the suitable position of mould and can be produced, has reduced the process, and the time of having practiced thrift, the cost is reduced improves product quality simultaneously, avoids obviously raising the efficiency because of the multiple operation circulation causes hourglass process.
Description
Technical field
The utility model relates to a kind of cold punching die, and 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 purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of cold stamping device for hole flanging chamfering integrated technique, can realize the integrated technique of hole flanging chamfering, decrease operation, save the time, reduced cost; Improve product quality simultaneously, avoid, because multiple operation circulation causes leakage operation, raising the efficiency.
According to the technical scheme that the utility model provides, 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 described in the utility model, adopt integrated design, adopt hole flanging punch and the die according to shape of product copying, application of installation described in the utility model 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.
