Abstract
The invention relates to a punch of a press machine. The punch comprises a punch body and a punch shell for fixing the punch body, wherein a clamping platform is arranged at the upper end of the punch body. The punch is characterized in that carbon steel is used as a matrix of the punch body, a plurality of groups of cemented carbide blocks are arranged in the matrix of the punch body at intervals, and a polyurethane pad is arranged between the clamping platform and the inner wall of the punch shell. The punch of the press machine has good impact toughness, or is not fractured during working, so that safety production is guaranteed; the punch is high in hardness and good in wear-resisting property, so that service life of the punch is prolonged, production and use costs are reduced, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of stamping parts, be specifically related to a kind of press ram.
Background technology
Forcing press carries out punching press by drift to workpiece, the existing drift for forcing press becomes one, it is for adding man-hour to workpiece, damaging largely easily appears in the position of drift and absorption surface, because drift becomes one, its local damage is scrapped with regard to entirety, and generally adopts steel alloy for the drift of punching press, cost is higher, once scrap the raising that will cause production cost.
Summary of the invention
The present invention seeks to provide a kind of press ram to overcome the deficiencies in the prior art, it not only there is higher toughness and also hardness high, avoid the excessive drift that causes of impulse force to damage.
For achieving the above object, the technical solution used in the present invention is: a kind of press ram, comprise the drift shell of drift body and fixing drift body, described drift body upper end is provided with clamping platform, described drift body adopts carbon steel to be matrix, is interval with and organizes hard alloy blocks more in the matrix of described drift body; Urethane pad is provided with between described clamping platform and drift outer casing inner wall.
Preferably, described hard alloy blocks material is 4Cr22MoCu.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of press ram of the present invention program, not only there is good impact flexibility, in the course of the work, drift can not rupture, and provides guarantee to safety in production, and its hardness is high, there is good anti-wear performance, improve the service life of drift, thus reduce manufacture and usage cost, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of press ram of the present invention;
Wherein: 1, drift body; 2, drift shell; 3, clamping platform; 4, hard alloy blocks; 5, urethane pad.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is a kind of press ram of the present invention, comprise the drift shell 2 of drift body 1 and fixing drift body 1, described drift body 1 upper end is provided with clamping platform 3, described drift body 1 adopts carbon steel to be matrix, is interval with many group hard alloy blocks 4 in the matrix of described drift body 1; Between described clamping platform 3 and drift shell 2 inwall, be provided with urethane pad 5, play the effect of punching press buffering; Described hard alloy blocks material is 4Cr22MoCu.Press ram of the present invention, not only there is good impact flexibility, in the course of the work, drift can not rupture, and provides guarantee to safety in production, and its hardness is high, there is good anti-wear performance, improve the service life of drift, thus reduce manufacture and usage cost, improve production efficiency.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
