Wide and thick sheet all hydraulic multi-roller temperature straightening machine HGC hydraulic cylinder dismounting and mounting method

Abstract

The invention provides a wide and thick sheet all hydraulic multi-roller temperature straightening machine HGC hydraulic cylinder dismounting and mounting method. The HGC hydraulic cylinder dismounting method comprises the following steps of S1) the releasing step of a peripheral connecting component of an HGC hydraulic cylinder; S2) the releasing step of a valve stand and / or pressure cylinder valve stand; S3) the mounting step of a sliding groove frame; and S4) the moving-out and dismounting step of the HGC hydraulic cylinder. The HGC hydraulic cylinder mounting method comprises the steps ofs1) the moving-in and mounting step of the HGC hydraulic cylinder, s2) the dismounting step of the sliding groove frame; s3) the mounting step of the valve stand and / or pressure cylinder valve stand;and s4) the connecting step of the peripheral connecting component of the HGC hydraulic cylinder, that is, the reverse flow operation of the HGC hydraulic cylinder dismounting method. According to themethod, dismounting and mounting of the HGC hydraulic cylinder are assisted by the sliding groove frame, so that the oblique pulling and hoisting of the major part of the HGC hydraulic cylinder is avoided, the large dismounting type dismounting and mounting mode of dismounting an upper cross beam is also avoided, the operation is facilitated, and the safety of personnel and equipment is guaranteed.

Description

technical field [0001] The invention relates to a method for disassembling and assembling an HGC hydraulic cylinder of a full-hydraulic multi-roller temperature straightening machine for wide and thick plates, and belongs to the technical field of maintenance of steel plate straightening machines. Background technique [0002] Full hydraulic multi-roll temperature straightening machine for wide and thick plates is one of the main equipment on the hot rolling production line. It is an important equipment to ensure good quality of steel plates. Defects such as fluttering or wave bending of wide and thick steel plates caused by deformation. [0003] In the prior art, the full-hydraulic multi-roll temperature straightening machine for wide and thick plates usually adopts a parallel multi-roll design, such as figure 1 As shown, it includes two upper beams set up side by side and the pressing frame installed at the bottom of the upper beams, as well as booster cylinders, valve ta...

AI Technical Summary

Problems solved by technology

[0010] However, during the maintenance process of the wide and thick plate fully hydraulic multi-roller temperature straightening machine, due to the obstruction of the upper beam and other equipment, the operating space is very small, and the disassembly and replacement of the HGC hydraulic cylinder is very difficult. In general, it is necessary to call the driving and 2 gourds cooperate to disassemble by oblique reverse movement, and the same method must be used for reassembly to complete the position

[0011] Due to the small working space on the fully hydraulic multi-roll temperature straightening machine for wide and thick plates and the inconvenience of personnel standing, the traditional method of disassembling and assembling the HGC hydraulic cylinder is difficult and risky
