Description

Clamping mechanism and high-speed wire recovery section guide groove

Technical Field

Background

The guide groove from the rear of the 0# water tank to the 3# flying shear section of the high-speed wire rod is called a recovery section guide groove, and the section guide groove consists of a plurality of groups of flip sliding guide grooves and is fixed on a channel base through 4 bolts respectively. In the rolling process, the rolled piece quickly passes through the sliding guide groove to generate mutual friction with the bottom of the guide groove, and the bottom of the guide groove quickly grinds a deep groove similar to the rolled piece in appearance, so that the rolling center line is lowered. When rolling different product gauges, the sizes of rolled pieces are different, and when the size of the rolled piece is smaller than that of a deep groove, the head of the rolled piece easily impacts the gap between the guide grooves, so that steel flying faults are caused; when the size of the rolled piece is larger than that of the deep groove, the deep groove is easy to clamp steel, and steel blocking faults are caused.

To ensure rolling stability, the centering error of the rolling center line must be controlled within + -1.5 mm. Because the guide groove is worn faster and can not realize on-line repair, the elevation requirement of the rolling line can be met only by a method of periodic replacement. The channels are typically replaced once a month, and multiple sets of channels are replaced simultaneously. When the guide grooves are replaced, the old guide grooves are required to be removed at the same time, after the new guide grooves are in place, a rolling center line is punched by using a level gauge, then the plurality of groups of flip sliding guide grooves are adjusted one by a method of adjusting the heights of the backing plates, so that the unified elevation is achieved, and finally, bolts are tightened for positioning. The replacement of the guide groove of the recovery section is very tedious, time-consuming, labor-consuming, and has great labor capacity, and the normal development of production is seriously affected.
