Temper mill transmission side segmented linear guide rail roller replacement transverse moving device and using method thereof

Abstract

The invention relates to the field of replacement of rollers, roller seats or racks and particularly relates to a temper mill transmission side segmented linear guide rail roller replacement transverse moving device and a using method thereof. The device comprises a roller replacing frame vehicle (7), and is characterized by further comprising a first linear rail (1), a second linear rail (2), sliding blocks (3), a first rail bracket (4), a second rail bracket (5) and a transverse moving push-pull hydraulic cylinder (6), wherein the sliding blocks (3) are sequentially embedded in the first linear guide rail (1) and the second linear guide rail (2), and the bottom of the roller replacing frame vehicle (7) is fixed to the sliding blocks (3). The method is characterized by being implemented according to steps in sequence, a, mounting; b, traversing. The device is convenient to operate, stable in running and convenient to install.

Description

technical field [0001] The invention relates to the field of replacement of rolls, roll stands or racks, in particular to a roll-changing lateral movement device for segmented linear guide rails on the drive side of a skin pass mill and a method for using the same. Background technique [0002] For the six-roll skin pass mill driven by the upper and lower support rolls, in order to realize the hoisting and replacement of the rolls, it is necessary to use the traversing device of the roll changer to move the middle rolls of the work rolls out of the drive shaft area for hoisting operations. [0003] At present, the roller changing and traversing device on the driving side of the six-roller skin pass mill usually adopts the form of rollers or sliders, and the track adopts the design of two sections of disconnected tracks at the entrance and exit, which are used to avoid interference caused by the swing of the transmission shaft and hoisting of the transmission shaft. The disad...

AI Technical Summary

Problems solved by technology

The disadvantage of the roller form is that the height of the rack for changing the rollers is too much. Once the roll diameter is large, the height of the rolling line needs to be increased accordingly; the disadvantage of the slider form is that the sliding friction coefficient is large, which leads to the thrust required for lateral movement. Larger, the driving hydraulic cylinder must also choose a larger model, and at the same time, there is a risk of derailment when the slider moves across the rails, and the failure rate of roller replacement is high
