Position control method of edge mill

Abstract

The invention provides a method for controlling the position of an edger, which belongs to the field of position control of an edger. The invention includes: determining the positioning accuracy and rolling control accuracy of the edger, the rolling control accuracy can meet the requirements of the production process, the absolute value of the positioning accuracy is smaller than the absolute value of the rolling control accuracy; during the edger positioning Using positioning accuracy, when the actual position of the edger runs within the range of positioning accuracy, the positioning is completed; using rolling control accuracy during the rolling of the edger, when the position of the edger exceeds the rolling control accuracy, rolling is interrupted. The present invention adopts a multi-level precision control mode to control the positioning accuracy of the edge rolling machine, and realizes that the positioning accuracy and the rolling control accuracy are separated and interlocked with their respective control programs, which improves the positioning accuracy of the edge rolling machine and satisfies the technical requirements of the edge rolling machine. The control demand ensures the stability of the edge mill.

Description

technical field [0001] The invention relates to the field of position control of an edger, in particular to a method for controlling the position of an edger. Background technique [0002] The positioning accuracy of universal E1 edge mill is ±1mm. Within the range of positioning accuracy, the equipment does not adjust it, and its position protection value is ±1mm at the same time. When the position exceeds ±1mm, the system enters the interruption mode. [0003] Since the edger is a movable device, the frame of the edger must be locked during rolling so that the edger can pass through the steel normally. After the edger equipment moves into place, there is a process of waiting for the edger frame to be locked. However, according to the characteristics of hydraulic equipment: the hydraulic cylinder inevitably has internal leakage; the compressed hydraulic oil has a small energy release when the main oil circuit is cut off. Therefore, after the frame is locked, it often happ...
