A material performance testing machine with nitriding function

Abstract

The invention discloses a material performance testing machine with nitriding function, which belongs to a material performance testing machine, comprising a frame and a nitriding box fixedly connected to the frame. The working fixture, the heating coil surrounding the workpiece extending into the nitriding box, the nitrogen nozzle extending into the nitriding box, and the working fixture is connected with a power mechanism that drives the working fixture to stretch or compress the workpiece. Compared with the ordinary testing machine, the present invention has added the function of nitriding, can study the effect of nitriding under the action of material stress and the performance of the material after nitriding, and is convenient for studying the performance of the material after nitriding under different tensile and compressive stresses, saving The process and time are shortened, which facilitates the research and development of new materials and the strengthening treatment and research of existing materials.

Description

technical field [0001] The invention relates to the related field of testing technology, and belongs to a material performance testing machine. Background technique [0002] The material performance testing machine is a device used for material performance experiments. Its main function is to test the performance of various materials. At present, the material performance testing machine in the world has made great progress since its birth. [0003] In industrial production, quality assurance is the key to whether the product can exist and circulate in the market. In military products with particularly high quality requirements, the inspection of various materials and the performance of various products will be more stringent, usually using High-precision, high-reliability material performance testing machine is used to systematically check materials or products. Whether it is in heavy industry, light industry, agriculture, or other industries, many large-scale machinery wil...

Problems solved by technology

[0005] However, the current problem is that there is no testing machine capable of both heat treatment and material performance testing. For some test pieces that need heat treatment such as nitriding, it is often necessary to carry out nitriding treatment in the nitriding furnace before sending them to the material performance test. The performance test of the test machine is complicated and time-consuming. This process is not economical and the efficiency is too low.
