A steel wire rotating bending fatigue testing machine

Abstract

The invention discloses a rotating bending fatigue testing machine for a steel wire. The rotating bending fatigue testing machine comprises a machine seat arranged at the bottom and a case arranged on the upper part, and is characterized in that the testing machine is a two-group testing machine with a vertical type framework structure, wherein driving motors, driven box bodies and an electrical appliance control box are respectively arranged in the case; direction adjustment worm wheels are arranged at the bottoms of the driving motors and the driven box bodies; angle direction adjustment shafts are arranged above the direction adjustment worm wheels; direction adjustment worms and direction adjustment worm wheels are arranged at two ends of the angle direction adjustment shafts; direction adjustment handwheels are arranged at the right ends of the angle direction adjustment shafts; distance scales are arranged above the driven box bodies; angle rulers are arranged below the driven box bodies; the bottoms of the driven box bodies are connected with box body supports; guide light bars and transmission screw rods are arranged at two ends of the box body supports; displacement handwheels are arranged at the right ends of the transmissions screw rods; clamps are arranged at two opposite ends of the driving motors and the driven box bodies in the coaxial direction; test sample brackets are arranged below the clamps; guide wheels are arranged in the test sample brackets. With the adoption of a touch screen type PLC (programmable logic control) system and an eight-bit counting system, the rotating bending fatigue testing machine for the steel wire has the functions of rotating speed output control, cyclic test, comparison test and the like.

Description

technical field [0001] The invention relates to the technical field of measuring physical parameters of metal materials, in particular to a testing machine for testing the rotational bending fatigue performance of steel wires. Background technique [0002] At present, there is no special steel wire rotating bending fatigue testing machine in China. Due to the lack of testing equipment for the physical performance testing of steel wire products, there is a vacancy in the physical testing of steel wire products. The traditional method is based on the tensile testing of steel wire products. The test results of physical properties such as strength, winding, torsion, etc., speculate on the performance parameters of its rotational bending fatigue. This kind of method has problems such as theoreticization of measurement data and excessive data errors. Therefore, in actual use, problems such as waste of resources or potential safety hazards caused by the inability to determine the ...

[0002] At present, there is no special steel wire rotating bending fatigue testing machine in China. Due to the lack of testing equipment for the physical performance testing of steel wire products, there is a vacancy in the physical testing of steel wire products. The traditional method is based on the tensile testing of steel wire products. Test results of physical properties such as strength, winding, torsion, etc., and speculate on the performance parameters of its rotational bending fatigue

This method has the problems of theoretical calculation data and large data errors.

Therefore, in actual use, there will be problems such as resource waste or safety hazards caused by the inability to determine the exact performance of the product
