a movable punching die comprises a punching die shell, wherein one end of the punching die shell is sleeved with a punching die core, the other end of the punching die shell is sleeved with a punching pad, the punching die core is sleeved with a punching rod, a blank rod is sleeved at the outer end of the punching die core and abutted against the punching rod, a die cavity of the punching die core is correspondingly provided with an end forming cavity, and a formed product with an end is formed in the end forming cavity by the blank rod after punching.

When the upsetting machine works, the problem that the material is bent when the upsetting proportion of the length (L) and the diameter (D) of the material at the head of the product is too large can be solved; when the punch rod extrudes the blank to form the head of the product, the blank can be formed in the die cavity of the die core, the problems that the head and the rod of the product are not concentric under the condition that the blank is bent in the forming process can be avoided, and the shape of the head of the formed product is more regular.

As a further aspect of the present invention: the end becomes the die cavity and is convex, is convenient for form the arc end, and end becomes die cavity outer end inboard and is provided with the arc chamfer for end outer end edge is level and smooth, is difficult for appearing burr etc..

As a further aspect of the present invention: the punching rod is characterized in that one end of the punching rod is provided with a punching pier head corresponding to the punching pad, the strength of the end part of the punching rod is increased, the service life of the punching rod is prolonged, the other end of the punching rod is provided with an end head groove corresponding to the blank rod, and the punching rod is in contact with the blank rod in the punching process, so that the forming effect of the middle part of the end head is good.

As a further aspect of the present invention: and a strong spring is arranged between the punching pad and the punching die core, so that a molded product after punching can be conveniently withdrawn from the die cavity of the punching die core.

As a further aspect of the present invention: the punching pad is a T-shaped punching pad, so that the strength of the end part of the punching pad is increased, and the service life of the punching pad is prolonged;

compared with the prior art, the utility model discloses the beneficial effect of following several aspects has:

the utility model provides a movable punching die, which can solve the problem that the material can be bent when the upsetting proportion of the length (L) and the diameter (D) of the material at the head part of the product is too large; when the punch rod extrudes the blank to form the head of the product, the blank can be formed in the die cavity of the die core, the problems that the head and the rod of the product are not concentric under the condition that the blank is bent in the forming process can be avoided, and the shape of the head of the formed product is more regular.
