Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] Such as figure 1 , the mechanical structure of the rolling mill is composed of a steel frame support, a roll driving mechanism and a pulling mechanism. The roll is driven by a hydraulic motor, and the upper roll is controlled by a servo cylinder to move up and down. The pulling mechanism is composed of a guide column and a hydraulic clamping device. The horizontal servo cylinder is controlled to move in the horizontal direction. The pressure is stabilized by the hydraulic accumulator, and the output torque of the hydraulic motor is controlled by a proportional pressure reducing valve. The displacement and speed in the X and Y directions are detected by two rotary encoders.

[0015] Such as figure 2 , The controlled quantity of rolling mill control system can be divided into analog quantity part and switch quantity part. The analog part consists of four circu...

Abstract

A vehicle variable cross section plate spring rolling mill computer control system employs an IBM-PC industrial control computer and a programmable controller for control, and employs a multi-modal intelligent control algorithm to obtain a good control effect; the control system is flexible in a control strategy, simple in algorithm, strong in servo tracking ability, strong in robustness, good ina control effect, and not sensitive for system parameter changes.

Description

technical field [0001] The invention relates to a computer control system for a variable-section leaf spring rolling mill for automobiles, which is suitable for the mechanical field. Background technique [0002] The variable section rolling mill is the key equipment for producing variable section leaf springs for automobiles. It will heat the constant section spring steel plate to 950℃ through the rotating roller compression and drawing mechanism to make its cross section change according to the designed deformation curve. At present, domestic leaf spring manufacturers either use imported rolling mills such as some products of British Searle Company and German Polk Company, or use domestically produced three-roll rolling mills imitating Searle Company and some simple rolling mills. The products produced by the simple rolling mill have low precision and large width, and the domestic three-roll rolling mill consumes a lot of energy and the volume of the equipment is relative...
