Abstract
The utility model discloses a punch pin. The punch pin comprises a cylindrical punch needle body; the punch needle body is sleeved by a punch needle fixing sleeve; the top end of the punch needle body is provided with a circular conical surface matched with the conical surface on the inner wall of the punch needle fixing sleeve; a puller bolt screwed on the inner wall of the punch needle fixing sleeve is arranged above the punch needle body; and a locking screw is propped against the side wall of the punch needle body. As the puller bolt is pressed at the top end of the punch needle body, the utility model has the advantages of high punch pin installation stability and product punching precision, and improves production efficiency.
Description
Technical field
The utility model relates to a kind of drift.
Background technology
Drift also is punch, patrix, formpiston, towards pin etc., drift is that drift is mounted in the metal parts in the diel, is applied to contact with the direct of material, makes material generation deformation, cuts material.Mold and punching head generally adopts high-speed steel and wolfram steel etc. as material, and high-speed steel drift and wolfram steel drift are arranged.Be installed in mould on the forcing press and directly contact after having assembled mold and punching head, make material generation separation or plastic deformation, thereby obtain required part with material (metal or nonmetal).
The utility model content
The purpose of this utility model provides a kind of drift, the installation good stability of drift, and the punching precision height of product has improved production efficiency.
The technical solution of the utility model is as follows:
A kind of drift, include columniform towards the pin body, outside the pin body, be set with towards the pin fixed cover, top towards the pin body has taper seat, taper seat cooperates with conical surface of inboard wall towards the pin fixed cover, there is the puller bolt that is screwed together in towards pin fixed cover inwall top towards the pin body, has screwed togather lock-screw on the sidewall of pin fixed cover, and the lock-screw roof pressure is on the sidewall of pin body.
Puller bolt of the present utility model is pressed the top of putting with towards the pin body, the installation good stability of drift, and the punching precision height of product has improved production efficiency.
