Abstract

The invention relates to a material erosion testing machine, and belongs to the technical field of material testing machine design and manufacturing. According to the material erosion testing machine, a grid plate platform is arranged in a testing machine housing and is provided with a material feeding device, the upper portion of the material feeding device is provided with a sand material bin, the sand material bin is provided with a sand material controller, a wind control device is arranged outside the testing machine housing, the lower outlet of a gas material mixing tank is provided with a spraying nozzle, and a speed measurement device is arranged under the gas material mixing tank. The work method comprises that: a detected material sample is placed on a detection platform, a sand material enters the material feeding device from the sand material bin, then enters the gas material mixing tank, and is sprayed on the surface of the tested material sample in a high speed manner through the spraying nozzle under the effect of the wind control device to carry out impact erosion, and the sample is subjected to inspection determination. According to the present invention, the material erosion testing machine has characteristics of simple structure and reasonable design; and the material feeding device, the wind control device and the speed measurement device are arranged so as to substantially increase the automation degree, achieve the required detection precision, expand the detection range of different materials, substantially reduce the production cost, optimize the product structure, reduce the failure rate, and solve the problems of the existing equipment.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of material testing machines. Background technique [0002] For metals and other materials used to manufacture a certain special product, an erosion test, that is, an impact and wear resistance test, must be carried out after production and before leaving the factory. After the test, the required data can be obtained to ensure the quality of the product. At present, some of the testing machines used for erosion tests of various materials use high-speed cameras as speed measuring devices, and some use laser Doppler speed measuring devices. Some of the feeding systems use belt feeders, and some use gear feeders. These forms of testing machines all have the problems of complex structure and high cost. Due to the complex structure, the failure rate of the machine is high. In particular, high-speed cameras and Doppler speedometers are prone to failure due to machine vibration and dust...
