AI Technical Summary

Technical Problem

When metallic materials move relative to each other, the heat generated by friction may cause the material to be too weak, potentially causing it to crack or break during testing, posing a serious safety risk.

Method used

A test bench for thermal friction properties of metallic materials was designed. It adopts a protective cover and a drive mechanism. The protective cover is driven to move linearly by a threaded rod. Combined with the self-locking transmission of worm gear and worm rack, it can stably clamp and protect metal rods of different diameters. Nickel-based alloy materials are used to reduce friction and heat loss.

Benefits of technology

It effectively reduces the risk of safety accidents, improves the flexibility and safety of testing, can adapt to test bars of different diameters, and is simple to operate and has high installation efficiency.

Abstract

The utility model relates to the technical field of metal material performance test, and provides a metal material thermal friction performance test bench which comprises a test bench, a connecting block fixedly connected to the middle of the top end of the test bench, a friction rod fixedly connected to the top end of the connecting block, and a connecting plate fixedly connected to the side end of the test bench. A driving motor is mounted at the top end of the connecting plate, and an output shaft of the driving motor is fixedly connected with a fixing mechanism; two symmetrically-distributed mounting plates are fixedly connected to the two side ends of the test board, threaded rods are in threaded connection with the interiors of the mounting plates, and protective covers are slidably connected to the positions, located on the two sides of the friction rod, of the test board. According to the utility model, by rotating the threaded rods at the two sides, the protective covers matched with the threaded rods can be driven and extruded to carry out linear motion, and when a test is carried out, the protective covers at the two sides can be closed, so that a protection function can be realized in a thermal friction experiment, and the risk of safety accidents is reduced.
