Description
Technical field
The utility model belongs to cold-heading technical field of mechanical equipment, is specifically related to a kind of novel cold-heading die assembly.
Background technology
Cold-heading equipment take upsetting as the main equipment being used for producing in batches the securing members such as nut bolt specially, it utilizes metal flow theoretical, at normal temperatures certain pressure is applied to metal stock, stock is made to carry out flow, normally for making the securing member such as screw, nut according to the shape and size of regulation in die cavity.In processing process, the stamping press of punch die is applied to stock, while needing by thimble, stock to be ejected, punch die top is moved back, power when such thimble ejects is larger, often red seat is subject to punching press simultaneously, and its stressed loss is serious, is easily out of shape, affect formed product, and frequent red seat of changing can cause high cost.
Utility model content
The purpose of this utility model is for the limitation existing for prior art and provides a kind of novel cold-heading die assembly.
In order to solve technique scheme, the utility model adopts following technical scheme:
A kind of novel cold-heading die assembly, comprise red seat and punch die, described red seat is provided with punch die groove, described punch die is arranged in described punch die groove, it is characterized in that, described punch die comprises sleeve, first red needle, described sleeve inner base plate is provided with cylindrical bump, spring is provided with on the right side of described projection, the first red needle is provided with on the right side of described spring, described first red needle top is provided with cylinder shape groove, the first through hole for fixing the second red needle is provided with in described cylinder shape groove, second through hole, third through-hole, fourth hole, the axis of described first through hole is consistent with the axis of described punch die, described second through hole, third through-hole, fourth hole is evenly distributed in described cylinder shape groove, fifth hole is provided with outside described first red needle top cylindrical connected in star, 6th through hole, 7th through hole, described fifth hole, 6th through hole, thimble is provided with in 7th through hole, with described spring contact bottom described thimble.
As preferably, have buffer stopper on the left of described sleeve, described buffer stopper is T-shaped round table-like.
As preferably, the length of described thimble is all greater than the length of described fifth hole, and the length of described thimble is all greater than the length of the 6th through hole, and the length of described thimble is all greater than the length of the 7th through hole.
The beneficial effects of the utility model are: compared with prior art, buffer stopper is provided with in a kind of novel cold-heading die assembly of the utility model, when buffer stopper, because of stressed loss, deformation occurs, can direct exchange buffering block and without the need to changing red seat and sleeve, be delayed the service life of red seat, reduce cost; Simultaneously, when the stressed punching press stock of punch die, thimble contacts with the backform outside stock, by spring side pressure left, at this moment thimble ejects and then makes punch die and backform to be just separated immediately after contact to the right by the tension force of spring, and backform because of stressed loss, deformation probability occurs and diminishes.
