 Impact specimen notch projector xt-50

Impact specimen notch projector xt-50

Product brand: Impact test specimen projector

Classification: impact specimen notch projector xt-50

Impact test projector, impact sample notch projector, specially used for Charpy V-notch impact test, compared with the standard drawing board, the notch pattern is magnified by 50 times. Due to the strict requirements for the V-notch of the sample (the notch depth of the sample is 2mm, the angle is 45 ° and the notch tip of the sample is required to be r0.25 ± 0.025mm)

Product introduction:
The impact specimen notch projector xt-50 is a special optical instrument to check the notch processing quality of Charpy V-shaped and U-shaped impact specimens. In order to meet the actual needs of users and the requirements of GB / t229-2007 "metallic materials Charpy pendulum impact test method", the V-shaped or U-shaped notch contour of the tested impact sample is magnified and projected onto the projection screen by optical projection method, and compared with the standard sample plate diagram to determine whether the notch processing of the tested impact sample is qualified. At present, it is the only practical and feasible method to ensure the quality of inspection.
Technical background:
For the Charpy V-notch impact test, due to the strict requirements for the V-notch of the sample (the notch depth is 2mm, the angle is 45 ° and the notch tip of the sample is required to be r0.25 ± 0.025mm), therefore, in the whole test process, whether the V-notch processing of the sample is qualified has become a key problem. If the processing quality of the sample defect is unqualified, the test result is not credible, especially the r0.25mm notch The tiny change of the tip (the tolerance zone is only 0.025mm) will cause the sharp jump of the test results, especially in the critical value of the test, it will cause two opposite results of the product or scrapped or qualified. In order to ensure that the processed Charpy V-notch is qualified, the notch plus quality inspection is an important means of quality control. It is the only feasible method to use optical projection to enlarge the inspection and ensure the inspection quality.
Application:
Xt-50 impact specimen gap projector is the first choice for metallurgy, boiler and pressure vessel, steel plate, steel pipe, wind power generation, hardware, metal, casting, pump, valve, solar energy, military industry, fastener, diesel engine, railway, shipping, machinery manufacturing, petroleum, automobile, chemical industry, aviation, physical and chemical laboratory, scientific research and other departments.
