Embodiment Construction

[0009] Depend on figure 1 It can be seen that when the skew roll leveler adjusts the roll gap of the straightening roller, after the electrical control system sends out the command (i) of the roll gap movement, the roll gap control circuit (1) in the PLC receives the roll gap adjustment command After (i), the instruction is amplified by the servo valve control amplifier (2) to drive the servo valve (3) to act, and the pressure oil of the hydraulic system enters (or flows out) the roller through the P port (or T port) and through the servo valve (3) The seam servo surveys the fast-reverse cylinder (5), and the plunger of the servo cylinder moves out (or retracts), and the displacement of the plunger is detected and fed back by the displacement sensor (6) connected with the cylinder plunger In the roll gap control circuit (1), after comparing with the received roll gap adjustment command (i), when the compared difference reaches the displacement accuracy set by the system, the r...

Abstract

A servo roller-gap regulation and fast moving back combined system for the cross-roll straightening machine of steel tube features that a serve roller-gap regulation system consisting of a hydraulic regulation valve set and a servo cylinder with displacement sensor is used, and the displacement of the plunger in cylinder is controlled by electric and hydraulic systems.

Description

technical field [0001] The invention relates to a roll gap adjustment device and a quick opening and pressing oil cylinder of a skewed roll straightener, which is one of the finishing equipment in metallurgical machinery, in particular to a servo adjustment and fast roll gap adjustment of a skewed roll straightener. Return combination system. Background technique [0002] At present, the roll gap of the skewed roll straightening machine needs to be based on the diameter of the straightened rolled material, using the motor or manual as the driving force, and the rotation of the screw driven by the reducer, and the change of the relative position between the screw and the nut. To adjust the size of the roll gap. This adjustment method cannot realize the adjustment of the roll gap during the straightening process of the rolled piece, so it takes a long time for adjustment to achieve the best roll gap value. There is no continuous real-time detection of dynamic straightening f...
