Experiment device for simulating damage failure of conducting roller by work conditions

Abstract

The invention discloses an experiment device for simulating the damage failure of a conducting roller by work conditions. The experiment device comprises a plating bath, bearing brackets arranged on two sides of the plating bath as well as an upper roller and a lower roller which are arranged in the plating bath, wherein two sides of the upper roller and the lower roller are respectively connected with the bearing bracket; the lower roller is connected with a driving speed regulating motor through a coupling; the upper roller and the lower roller are connected through an upper driving gear and a lower driving gear; rolling bearings connected with the upper and lower rollers are arranged in the bearing brackets; a collecting ring connected with the upper roller is arranged between the plating bath and the bearing bracket; water cooling rotary connectors are connected to two ends of the upper roller; an upper roller polishing block is also connected to the upper roller and is connected with a reversible motor through a ball screw; an anode plate and an upper conducting roller are arranged in the plating bath; and a preheating supplement groove is also arranged in one side of the plating bath. According to the experiment device disclosed by the invention, actual work conditions of the conducting roller can be simulated in multiple aspects; the simulation test for the damage failure of multiple conducting roller materials is developed; and a convenient and fast experiment method for developing new materials and processes is provided. In addition, the experiment device is simple and convenient in operation and easy for popularization.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device for simulating the damage and failure of conductive roller materials under working conditions. Background technique [0002] Conductor rolls are key components in continuous electroplating lines, transporting the steel strip and conducting the strong cathodic current during the electroplating process. Due to the harsh working conditions of the conductive roller, on the one hand, the conductive roller will contact the electroplating solution containing corrosive media such as hydrogen ions, sulfate ions, chloride ions, iron ions, etc. On the other hand, the surface of the conductive roller and the strip are constantly Friction causes wear. Therefore, in the actual use process, the surface quality of the conductive roller will deteriorate in a short period of time or even a short period of time (2 weeks to 2 months). etc.), which seriously affects the quality of el...
