Abstract

The invention provides a transverse three-rotation wheel force balance control method for a spinning machine. The transverse three-rotation wheel force balance control method comprises the steps thatthe initial pressing positions of rotation wheels and the dip separation quantity between the rotation wheels are set; the initial pressing quantity correction time and the pressing quantity correction sampling periods of the rotation wheels are determined; after the rotation wheels are in position, pressure data of the rotation wheels are collected; the trajectory of the third rotation wheel is determined, and the rotation wheel standard pressure value is determined; and at the initial pressing quantity correction time of the first rotation wheel, according to the collected pressure data of the first rotation wheel and the standard pressure value, the pressing quantity of the first rotation wheel is corrected for the first time, and then the pressing quantity of the first rotation wheel is corrected at each pressing quantity correction sampling period. The transverse three-rotation wheel force balance control method can achieve the aim of controlling the balance of transverse force ofthe three rotation wheels in the spinning processing procedure. According to the transverse three-rotation wheel force balance control method, the magnitude of the spinning force of the first rotation wheel and the second rotation wheel are actively adjusted in sequence, the radial displacement variable of the three rotation wheels is calculated by a numerical control system and automatically adjusted, and the purpose of the transverse force balance control of the three rotation wheels is achieved.

Description

technical field [0001] The invention relates to the technical field of pressure processing of metal pipes, in particular to a method for controlling the force balance of a horizontal three-rotor wheel of a spinning machine. Background technique [0002] Spinning forming technology is a pressure processing technology that makes use of the approximate point contact between the wheel and the workpiece and high unit pressure to locally deform the processed material. This forming technology has high material utilization and significantly improved processing performance. It is suitable for high It has the characteristics of processing high-strength and difficult-to-deform materials, and integral processing of seamless rotary hollow parts. Among them, three-rotor powerful spinning is one of the main spinning forming technologies. It has the characteristics of large spinning tonnage, automatic centering of three-rotor, and high spinning accuracy. It is widely used in thin-walled cyl...
