A fixing and replacement device for the proximity switch of the card plate of a finishing mill

Abstract

The invention discloses a fixing and replacement device for a card plate proximity switch of a finishing mill. The outer edge of the moving base is fixed on the lower card plate of the work roll through an adjustable bracket, and the inner edge is provided with a plurality of radial shrapnel for clamping the external thread of the proximity switch. The torsion bar is rotatably connected with the torsion bar fixing frame fixed on the mobile base, the rear end of the torsion bar rotates the handle, one end of the swing bar is connected with the head end of the torsion bar, and the other end is disassembled and assembled through the snap ring fixing frame The outer edge of the snap ring is attached. The invention uses the switch snap ring to fix the proximity switch, and uses the disassembly snap ring to remove the proximity switch car from the switch snap ring or install it on the switch snap ring. The difficulty of replacing the board proximity switch improves the maintenance efficiency of the board proximity switch.

Description

technical field [0001] The invention relates to a device for fixing or replacing a proximity switch of a finishing mill clamping plate, belonging to the technical field of metal rolling. Background technique [0002] Some hot-rolled coil finishing mills use clamping plates to lock the position of the work rolls in the rolling mill. The upper clamping plate and the lower clamping plate are a group, and a total of two groups of clamping plates are installed symmetrically on both sides of the work roll. The position signal comes from the block. Block-triggered proximity switches. Affected by factors such as water vapor, dust and oil leakage in the on-site environment, the service life of the proximity switch is greatly shortened and needs to be replaced frequently. However, because the proximity switch of the lower card board is close to the ground, its position is inward, and there are many cross-over devices around, and there is no working platform, it is very difficult to i...

Problems solved by technology

Affected by water vapor, dust, oil leakage and other factors in the field environment, the service life of the proximity switch is greatly shortened, and frequent replacement is required

However, since the proximity switch of the lower pallet is relatively close to the ground, its position is inward, and there are many cross-connected devices around it, and there is no work platform, it is very difficult to install, fix, maintain and replace the proximity switch of the lower pallet, which greatly increases the proximity switch of the pallet. The maintenance workload reduces the work efficiency, so it is necessary to design a device that can quickly and easily fix or replace the proximity switch of the clamping plate under the finishing mill
