The structure of testing machine can be divided into vertical and horizontal. Vertical is generally used for small tonnage machines, while large tonnage and long stroke machines are mostly horizontal. According to the requirements of MT/T99 industry standard, the precision of wire drawing machine is not lower than 1, and there is an automatic recording instrument. The fixture will also be used in the test, which is generally composed of connecting rod, stop and sleeve, and the connection mode with the connecting rod. The whole tensile test includes elongation test and breaking load test. Adelink will be inspected before leaving the factory, and all products meet the national regulations and industry norms. It not only puts forward higher requirements for the performance of the product materials, but also deeply cultivates the reasonable structure of the product and avoids the problems of difficult disassembly and insufficient reliability in the use of the product.
