Roll-stopping detection control device

Abstract

The invention relates to a detection control device, in particular to a roll-stopping detection control device in working for repairing the surfacing on the surface of a roll workpiece. The roll-stopping detection control device comprises a magnetic seat, a meter counting wheel and an elastic seat, wherein the meter counting wheel is fixed with the magnetic seat by the elastic seat; an output signal line of the meter counting wheel is connected with a welding machine control box. The top part of the meter counting wheel abuts against the surface of the surfaced roll tightly, rotates synchronously along with the roll, converts a rotating signal into a digital signal at any time, and conveys the digital signal to the welding machine control box; once the workpiece stops rotation, the welding machine control box receives a rotation-stopping signal and controls a weliding machine to stop welding so as to ensure that an overhigh surfacing layer is not formed at the end of the surfacing.

Description

technical field [0001] The invention relates to a detection and control device, in particular to a detection and control device for the stop of a roller during the surfacing welding repair work on the surface of a roller workpiece. [0002] Background technique [0003] Some roll workpieces, such as rolls of steel rolling mills, grinding rolls of coal mills and cement mills, etc., after a period of use, the surface is worn out, and the surface needs to be repaired by surfacing. During the surfacing process, the roller workpiece is fixed on the horizontal rotary table and rotates with the rotary table. After the surfacing welding is completed, the rotary table is controlled to stop rotating, and the welding machine is controlled to stop working simultaneously. [0004] The existing above-mentioned controls are mostly carried out manually. It is necessary to control the rotary table to stop rotating, and at the same time control the welding machine to stop wire feeding, and ...

AI Technical Summary

Problems solved by technology

[0004] The existing above-mentioned controls are mostly carried out manually. It is necessary to control the rotary table to stop rotating, and at the same time control the welding machine to stop wire feeding, and cut off the welding power supply to stop the arc. layer, which brings trouble to subsequent processing

If the welding power supply cannot be cut off in time to stop the arc, it will also cause cracks in the workpiece due to excessive heating.
