Electroplastic cross wedge mill

Abstract

The invention discloses an electroplastic cross wedge mill. The electroplastic cross wedge mill mainly comprises a radial adjusting mechanism, a rack, a roller system, a guide plate mechanism, an electroplastic device, a base, a pulsed power supply, a connecting rod, an upper bearing pedestal, a conical roller bearing A, a lower bearing pedestal, a conical roller bearing B, an end cover, a press-down screw and a press-down nut. The cannonball moving direction is stable, shooting accuracy is high, the range is long, and the electroplastic cross wedge mill is suitable for remote and precise fight of an electromagnetic railgun. Conventional cross wedge rolling equipment is improved, deformation resistance of a rolled piece is lowered, plasticity, tenacity and other mechanical properties are improved, design is reasonable, the structure is simple, time and labor are saved, heating equipment is not needed, operation is easy, and the electroplastic cross wedge mill has an obvious effect on rolling metal which is poor in plasticity, high in deformation resistance and hard to deform under normal temperature, and can be used for conducting cross wedge rolling on metal or alloy bar materials of different dimensions.

Description

technical field [0001] The invention relates to a cross wedge rolling mill. Background technique [0002] Cross wedge rolling is a widely used metal plastic processing method, and it is the main processing method of stepped shaft mechanical parts. Cross-wedge rolling technology is a new processing technology for shaft parts developed in recent decades. It uses two wedge-shaped dies mounted on co-rotating rolls to cause continuous local deformation of the billet, and finally rolls it into a wedge-shaped hole. Various types of stepped shafts. This technology is widely used in the production of various parts with rotating bodies because of its high efficiency, material saving, energy saving and other characteristics. [0003] Rolling at room temperature is generally understood as cold rolling. From a metallurgical point of view, the boundary between cold rolling and hot rolling should be distinguished by the recrystallization temperature. That is, rolling below the recrystal...

AI Technical Summary

Problems solved by technology

Hot rolling is difficult to realize the cold rolling process for metal materials that have high deformation resistance at room temperature and are difficult to deform but have good mechanical properties.

At the same time, during the hot rolling process, the temperature of the rolled piece gradually decreases, and the deformation resistance of the material gradually increases, and finally the hot rolling cannot be carried out, and because the temperature of the rolled piece is not easy to be uniform during rolling, and there are iron oxide scales on the surface, etc., the quality of the product Dimensional ac...
