Abstract

A horizontal down regulation method used for controlling the three rolls plate bending machine; firstly, ascertaining the radius, the sheet material width and the sheet material thickness of the work piece as well as the strength coefficient and the yield strength of work piece materials. Based on the optimizing of the remained straight edge, the horizontal shift, three vertical shifts and two depressing values are calculated out for coiling or pre-flex so as to spool out the cylinders with various diameters. The utility model has the advantages of high control precision and low trueness error for the roll bending.

Description

technical field [0001] The invention belongs to a control method of mechanical equipment, in particular to a plate rolling control method of a plate rolling machine. Background technique [0002] The horizontally adjustable three-roller plate rolling machine has a compact structure, simple operation, small remaining straight edges, and safe and convenient feeding. It is an ideal model for extra-heavy plate rolling. However, the current domestic plate rolling technology is based on the control model derived from the geometric model of this type of plate rolling machine under the mechanical model of the former Soviet Union, that is, referring to the fifth chapter of the "Mechanical Design Manual Volume Seven" "The geometric model and the control model derived from the mechanical model on pages 42-35 to 42-45 are used for control. The current coiling process is also compiled based on this model. This control model has played a guiding role in the operation of the coil for a lo...
