2 important preparations before the test of a universal test machine

My company wasUniversal testing machineThe operation and maintenance of the universal test machine plays an important role in the operation, but a complete operation still requires us to better prepare the test machine.

1, preparation of test pieces:Universal testing machineTake the gauge distance in the middle section of the specimen or use the foot marking gauge as marking markings, and use a vernier caliper to measure the center and the three diameters at both ends within the limit of the specimen gauge distance to calculate the cross-sectional area of ​​the specimen.

2, preparation of test machine:First, investigate the fundamental structure and operating methods of the data test machine and further study the operating procedures of the test machine. Based on the strength limit of low-carbon steel and the cross-sectional area of ​​the specimen, the load required for tensile specimen is initially estimated, the appropriate measurement dial is selected, and the responsive pendulum is equipped, the thought device is opened, the force measuring pointer is adjusted to "zero point", and then the position of the chuck under the test machine is adjusted, and the specimen clip is installed in the chuck.
