Abstract

The invention relates to a three-roller spiral pore type rolling mill which comprises a roller device and a frame, wherein the roller device comprises three roller components which are mounted on the frame in the shape of a Chinese character 'pin'; each roller component is composed of a roller, a roller pressing adjusting mechanism, a roller axial adjusting mechanism and a roller feeding angle adjusting mechanism; the roller pressing adjusting mechanism, the roller axial adjusting mechanism and the roller feeding angle adjusting mechanism which are arranged on the roller device are used for realizing the pressing adjustment, axial adjustment and feeding angle adjustment of the roller; and the roller component is organically combined with a phase angle adjusting mechanism, thereby being suitable for the rolling of various parts. Besides, the three-roller spiral pore type rolling mill has the advantages that the whole design is reasonable and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a metal rolling equipment, in particular to a three-roller spiral groove rolling mill. Background technique [0002] Compared with conventional process forging, spiral groove rolling has the advantages of high single-machine productivity, material utilization coordination and good product selection. In addition, it also has less equipment investment and can effectively reduce production costs and improve the working environment. In the 20th century In the 1950s, the former Soviet Union, Japan, the United States and other countries used spiral pass rolling technology to produce steel balls, screw rods and other products with high efficiency, and achieved significant economic benefits. my country began to use this technology in the 1960s. Developed single-pass, deep-shallow, and multi-head rolling equipment and processes. However, no matter whether it is domestic or foreign, the above-mentioned rolling equipment has the disadvanta...
