Control method for common roll grinding machine

Abstract

The invention mainly relates to a method for controlling a common roll girder, and belongs to the electric control technical field of common-type roll grinders. The method is characterized in that a PLC programmable logic controller (1) is not only connected with a programmable terminal display (2) through a PROFBUS data bus, but also connected with a control unit (3) through the data bus; the control unit (3) is connected with a servo driver (4) and a manual pulse generator (5) through the data bus. The invention has the advantages that the S7-300 PLC programmable controller is utilized, thelogic control of the programmable controller is adopted, and the manual pulse generator is adopted instead of a mechanical hand wheel so as to reduce the labor intensity of an operator. At the same time, the programmable terminal display is mounted for displaying the movable distance on each coordinate axis; the accurate tool advancement and alignment on a common roll grinder is realized; an electron transport chain is adopted instead of the mechanical transmission chain, so as to greatly improve the working efficiency and reduce the labor intensity of an operator.

Description

Technical field: [0001] The invention mainly relates to the technical field of electrical control for ordinary roll grinders, and in particular to a control method for ordinary roll grinders. Background technique: [0002] Roll grinder is an indispensable and important production equipment in modern industrial production. It is mainly used in metallurgy, papermaking and other industries. Its grinding mechanism has the characteristics of general large-scale cylindrical grinders, but it is different from general cylindrical grinders. In addition to grinding cylinders, (grinding flat rolls, roll support diameters), the grinding machine can also grind various roll surfaces with convex, concave and arbitrary curved surfaces on the rolling mill. The movement of the grinding wheel is much more complicated. In addition to the relative rotary motion (main motion) between the grinding wheel and the workpiece (roller), it is also required that the grinding wheel and the workpiece make ...

AI Technical Summary

Problems solved by technology

[0003] Due to the conventional ordinary roll grinder, the feed system of the grinding wheel passes through a long mechanical transmission mechanism, and feeds the knife through the mechanical hand wheel, and the operation is relatively laborious. Due to the existence of various gaps in the mechanical transmission, the feed is often inaccurate. , which brings a lot of trouble to the operator
