Non-polar oblique wedge adjustment mechanism

Abstract

The invention belongs to the field of rolling mill operation, and relates to a non-polar oblique wedge adjustment mechanism, which at least comprises a screw, a proximity switch, a hydraulic motor, two supporting seats, two oblique sliding blocks, a photoelectric encoder and a PLC (programmable logic controller), and is characterized in that: the two supporting seats are fixedly arranged on a rolling mill housing, and the two oblique sliding blocks are fixedly arranged at the same side of the screw by nuts; sliding grooves matched with the oblique sliding blocks are arranged on the two supporting seats, and the oblique sliding blocks are arranged in the sliding grooves of the supporting seats; and the hydraulic motor is connected with the screw by a shaft coupling, and a non-polar oblique wedge adjustment device is connected with the PLC controller, is controlled by the proximity switch arranged on the screw, and is also connected into a computer by the photoelectric encoder. The non-polar oblique wedge adjustment mechanism integrates a hydraulic and electronic control technology with a mechanical device, has the characteristics of large adjustment stroke, simple and compact structure, safe and reliable performances, high automation of operation, and convenience in setting, and can be used in various large-scale rolling mill operating lines.

Description

technical field [0001] The invention belongs to the field of rolling mill operation and relates to a stepless wedge adjustment mechanism. Background technique [0002] In the rolling mill operation line, due to the change of the roll system, the adjustment operation of the rolling line is often carried out. Especially for large-scale rolling mills, the grinding range of the roll system is large, and a large-stroke wedge adjustment device is required to complete it. In addition, for large-scale rolling mills, the rolling line adjustment device is generally installed on the top or bottom, which is inconvenient for manual observation or adjustment. It is required that its position must be automatically memorized and automatically adjusted; some domestic rolling mill adjustments use small-scale rolling line adjustment and backing plates in combination, and rely on manual backing plates. The adjustment time is long, the labor intensity is high and difficult, and the rolling line...
