Requirements for the use of steel reinforcement mechanical sleeve tensile testing machine

Jinan Liling Testing Machine Co., Ltd. specializes in the production and research and development of mechanical testing equipment.The steel reinforcement mechanical sleeve tensile testing machineis a customized processing machine developed and produced by Leading Testing Machine Company. Multiple user units in universities and testing stations have purchased and used this machine from Leading Company, and feedback has been received..

The steel reinforcement mechanical sleeve repeated tension and compression testing machine mainly implements a repeated tension and compression testing process for the connection parts of the steel reinforcement mechanical sleeve, requiring a force value of ± 1000kN in both tension and compression directions. Therefore, during the testing process, the clamping of the sample and the coaxiality of the test when applying tension and compression forces in both directions are quite important.

The repeated tensile and compressive testing process of the mechanical sleeve is to stretch it to near full range, and during the compression test, it generally reaches about 60% of the full range, and it needs to be tested back and forth in both directions of tension and compression. Therefore, there are high requirements for the clamping method during the force application process. In this regard, the GHAW series force testing machine has done a good job, using four hydraulic cylinders of bidirectional hydraulic flat pushing as the clamping actuating device. These four hydraulic cylinders effectively ensure the firmness of the clamping, and can uniformly and firmly apply the test force during the tensile and compression tests. The strong hydraulic flat pushing fixture is also used. Completely ensured the avoidance of slipping phenomenon.

The use of a four column structure with an upward hydraulic cylinder and a bidirectional hydraulic cylinder ensures the space for tensile testing. The bidirectional hydraulic cylinder enables efficient testing. At the same time, the repeated tension and compression equipment of this force testing machine is equipped with high-precision bidirectional extensometers, which also makes the stress-strain curve of the test data accurate and stable.
