摘要

摆动碾压技术，简称为摆辗，是近年来的一种新的压力加工工艺，经过不断的试验和努力才在20世纪中后期进入到实用阶段。

摆动辗压技术为连续局部成形，摆头的中心线与摆辗机机身的垂直轴线形成一个倾斜角，使得摆头与金属坯料之间实现滚动摩擦，从而摆头对坯料的成形压力只在工件的小部分表面上，这是与常规锻压技术锻压成形力作用在整个表面上所不同的。摆动辗压的变形力比较小，可以取代标称压力高于自己10倍左右的其他常规锻压设备。

摆辗成形长轴类零件（例如齿条）需要摆辗机能实现直线轨迹，目前国内大多采用从国外进口的四轨迹摆辗机，它利用双偏心套，通过变速箱控制转速来实现直线轨迹，这种四轨迹摆辗机结构复杂，制造成本和维修费用较高，并且偏心套结构在实现直线摆动时，由于双偏心套运动过程中会产生较大的振荡离心力，会使机身产生剧烈的振动，不利于企业对零件的大规模生产。

本文目的在于提供一种实现直线摆动的摆辗机，结构简单，制造简单，设备成本较低，还可以减少机身的振动。同时本文公开了一种实现直线摆动的摆辗机，包括机身、摆头机构、旋转机构和滑动机构。

Abstract

Rotary forging technology is a new pressure processing technology in recent years. It has been tested and tried to enter the practical stage in the middle of twentieth Century. Rotary forging technology is continuous local forming, the pendulum head of the center line and pendulum rolling machine body vertical axis to form a tilt angle, so that the rocker and the metal blank between the rolling friction, and conventional forging technology for forming masterpiece, the tilt of the head of the blank forming pressure only in a small part of the surface of the workpiece. Rotary forging deformation force is relatively small, so it can replace nominal pressure is higher than 10 times of other common forging and pressing equipment.

Rotary forging forming a long parts (e.g. the rack) need rotary forging function to achieve linear trajectory, currently the most widely used from foreign imports of four track swing forging machine, which uses double eccentric sets, through a gearbox speed control to achieve a straight line trajectory, this four track rotary forging machine structure is complex, manufacture cost and the maintenance cost is higher and eccentric sleeve structure in the realization of the straight-line swing, due to the double eccentric sleeve movement in the process will produce centrifugal force with large oscillation, can make the body to produce intense vibration, is not conducive to enterprise on the part of the mass production.

The purpose of this paper is to provide a linear oscillating rotary machine, simple structure, simple manufacturing, low cost of equipment, but also to reduce the vibration of the fuselage. At the same time, this paper discloses a swinging ring rolling machine, which comprises a body, a swing head mechanism, a rotating mechanism and a sliding mechanism.
