Problems solved by technology

[0003] The present invention solves the deficiencies of the above-mentioned technical problems, overcomes that the roll gap adjustment device of the existing skewed roll straightening machine cannot dynamically adjust the roll gap and the dynamic straightening force and reliably detect it, and at the same time overcomes the skewed roll straightening of the servo adjustment roll gap The machine cannot meet the requirements of rapid change of the roll gap under the condition of high speed and high precision. A servo adjustment of the roll gap and a fast retreat and pressing system are provided, which can solve the above technical problems conveniently and reliably.

Embodiment Construction

[0009] Depend on figure 1 It can be seen that when the skewed 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 movement command (i) i) Afterwards, the servo valve controller 2 amplifies the instruction and drives the servo valve 3 to act, and the pressure oil of the hydraulic system enters (or flows out) through the servo valve 3 through the P port (or T port) and enters (or flows out) the roll gap servo inspection fast-reverse oil cylinder 5 , the plunger of the servo cylinder is extended (or retracted), and the displacement of the plunger is detected by the displacement sensor 6 connected with the cylinder plunger and fed back to the roll gap control circuit 1, which is connected with the connected After the received roll gap adjustment command (i) is compared, when the compared difference reaches the displaceme...

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...
