Abstract
The utility model discloses a drift of punching press compressor valve piece through -hole, including the base, set up the punch rod on the base, set up in the toper portion on punch rod top and set up in the drift body on toper portion top and set up the reinforcement between toper portion and drift body, the bottom of reinforcement is the excessive structure of chamfer with the top of toper portion. The utility model discloses increase the reinforcement between toper portion and drift body, make the connection structure of drift body firmer, the utility model discloses it is excessive that the junction of reinforcement and toper portion be the chamfer, has further avoided the problem of breaking between reinforcement and the toper portion. The utility model discloses simple structure, overall structure rigidity are strong, the difficult rupture of drift, and whole life prolongs greatly.
Description
Technical field
The utility model relates to the manufacture field of compressor valve plate, specifically a kind of drift of ram-compressed machine valve block through hole.
Background technology
Seeing Fig. 1, is excessively connected by tapered portion between the drift body of the drift of existing stamping machine and plunger rod, in the process of punching press, is easy to fracture, needs often to change drift, cause the increase of processing cost between tapered portion and drift body.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of drift of ram-compressed machine valve block through hole, and its rigidity of structure is strong, drift body not easy fracture, long service life.
The technical solution of the utility model is:
A kind of drift of ram-compressed machine valve block through hole, include base, the plunger rod be arranged on base, be arranged at the tapered portion on plunger rod top and be arranged at the drift body on tapered portion top, it is characterized in that: connected by girth member between described tapered portion and drift body, the bottom of described girth member and the top of tapered portion are chamfering excessive structural.
The bottom end face of described drift body and the top end face of girth member are fitted completely.
Described girth member is cylindrical structural, and the top end face of girth member and sidewall are circular arc excessive structural.
Advantage of the present utility model:
The utility model increases girth member between tapered portion and drift body, makes the syndeton of drift body firmer; The junction of the utility model girth member and tapered portion is that chamfering is excessive, further avoid the problem fractureed between girth member and tapered portion; The bottom end face of drift body and the top end face of girth member are fitted completely, and the top end face of girth member and sidewall are circular arc excessive structural, while reducing, ensure hardness and the rigidity of Integral connection structure further.The utility model structure is simple, overall structure rigidity is strong, and drift is frangibility not, and whole service life extends greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of original drift.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 2, a kind of drift of ram-compressed machine valve block through hole, include base 1, the plunger rod 2 be arranged on base 1, be arranged at the tapered portion 3 on plunger rod 2 top, be arranged at the drift body 4 on tapered portion 3 top and be arranged at the girth member 5 of cylindrical structural between tapered portion 3 and drift body 4, the bottom end face of drift body 4 and the top end face of girth member 5 are fitted completely, the bottom of girth member 5 and the top of tapered portion 3 are chamfering excessive structural, and the top end face of girth member 5 and sidewall are circular arc excessive structural.
