Material performance test machine with nitriding function

Abstract

The invention discloses a material performance test machine with a nitriding function, and belongs to the material performance test machine. The test machine comprises a rack; a nitriding box fixedlyconnected to the rack, wherein a work holder for clamping two ends of a workpiece is arranged in the nitriding box; a heating coil extending into the nitriding box and surrounding the workpiece; and anitrogen sprayer nozzle extending into the nitriding box; the work holder is connected with a power mechanism for driving the work holder to stretch or compress the workpiece. The nitriding functionis increased in comparison with the normal test machine, the nitriding effect under the material stress effect and the material performance after nitriding can be researched, thereby facilitating theresearch on the performance of the material after nitriding under different tensile stress and compressive stress; the working procedure and time are saved, the research and development of the new material and the strengthening treatment and research on the existing material are convenient.

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.
