Device for detecting depth of hardening layer of roller body of cold rolling working roller

Abstract

The invention relates to the technical field of cold rolling working rolls, in particular to a cold rolling working roll body hardening layer depth detection device which comprises a detection device body, a control panel is arranged on one side of the detection device body, a limiting wheel is arranged on the surface of the detection device body, and a first belt pulley is arranged on the surface of the limiting wheel. A first limiting column is arranged on the inner side wall of the first belt pulley; and the reciprocating detection plate is installed on the surface of the movable plate, and the top end of the reciprocating detection plate is fixedly connected with a depth detector. According to the invention, the manipulator takes out the detected material and places the next material at the same time, so as to wait for the next reciprocating detection plate to slide forward for detection, and the detection result is transmitted to the interior of the display screen body through the depth detector for recording, so that the detection effect is greatly improved, and the detection efficiency is improved. The material can be continuously detected, the operation efficiency is high, and the detection structure is accurate.

Description

technical field [0001] The invention relates to the technical field of cold-rolled work rolls, in particular to a device for detecting the depth of a hardened layer of a roll body of cold-rolled work rolls. Background technique [0002] Cold rolling rolls are complex components with very hard surface layers and are subject to great stress. Therefore, cold rolling rolls require high manufacturing quality, which is a necessary condition to ensure the effect of use. Rolls used for cold rolling are generally flat rolls. For rolling sheets and strips, cold rolls in a broad sense include work rolls that are in contact with the rolling stock and backup rolls that play a supporting role. Because the backup rolls are self-contained, cold rolls are often referred to in a narrow sense. The roll must have sufficient strength, uniform high hardness and surface quality to withstand extremely high rolling force, ensure sufficient wear resistance, and meet the requirements of rolling precis...

Problems solved by technology

[0004] The object of the present invention is to provide a device for detecting the depth of the hardened layer of the cold-rolled work roll body, so as to solve the problem that the cold-rolled work roll body will have a certain depth of the hardened layer of the roll body before it is used. Inspection to ensure that the thickness achieved by the work can be achieved, but the most common method is to use slice inspection to detect the radial hardness of the hardened layer of the roll body, but this method is difficult to detect the hardness of some roll bodies The hardened layer is continuously detected in large quantities, and the existing detection device still needs to manually arrange the materials, which is time-consuming and laborious, the detection efficiency is low, and the detection accuracy is not high. The device as a whole is in use When the device is used, it also needs a certain functionality to assist the device to perform multi-functional operations.
