Fixed width traversing device of rolling cut type bilateral shear and mobile shear

Abstract

A fixed-width traversing device for rolling-cut double-sided shears used in the metallurgical machinery industry. , transmission screw, etc., install the lower steel belt on the top of the track base, and use the tensioning mechanism to tighten the steel belt, install the side steel belt on the side of the track base, and use the tensioning mechanism to tighten the steel belt. Insert the lower plate into the support plate and press it with the pressure plate, insert the side slide plate into the side support plate and press it with the pressure plate, then put the support plate and the side support plate together and assemble them as a whole on the track base with the steel belt ;Complete the assembly of the drive screw; put the adjustment wedge on the frame, then install the frame on the assembled track base, insert the adjustment wedge for overall adjustment, and lock the adjustment wedge when the technical parameters are met , and tighten the support plate on the frame, lock the locking plate, and the device is completed. The device has a novel and scientific conception, convenient adjustment and disassembly, no backlash transmission, no leakage, low manufacturing cost, fast and stable adjustment, and high precision of fixed-width control.

Description

Technical field: [0001] The invention relates to a fixed-width traversing device of a roll-cut type double-sided shear moving shear in the metallurgical machinery industry. The product mechanism is mainly used for adjusting the width of a sheared steel plate in a finishing area of ​​a wide and thick plate of a metallurgical rolled steel product. Background technique: [0002] The roll-cut double-sided shear is the key equipment in the finishing area of ​​the wide and thick plate rolling production line. It is mainly used for constant-width shearing of medium-thick steel plates. It has the advantages of straight, smooth, no deformation, high geometric precision and fast shearing speed. The fixed shears of rolling-cut double-sided shears are fixed on two parallel bases with pressure plates and bolts, and positioned with fixed keys. The mobile shears are installed on two track bases connected with the fixed shear bases. Most of the technology imported from abroad for the mobi...

AI Technical Summary

Problems solved by technology

When the static pressure plate on the bottom surface of the mobile shear is working, the gap between it and the upper surface of the track should be kept at a value of 0.05mm. Its processing, manufacturing and assembly are very difficult, and the oil leakage of this part is a problem for the equipment manufacturer when it is used on site. very difficult problem

In addition, it adopts the rack and pinion transmission mode, and its meshing gap cannot be eliminated, which has a certain influence on the fixed width accuracy.
