The WAW - J series features a single - space cylinder - up structure. The main cylinder is a bidirectional differential cylinder, enabling both tensile and compressive control within one space. It is equipped with a flat - push fixture. The machine uses a gap - free rigid structure, adjusting the test space directly through the piston's lifting, which ensures convenient and efficient operation.
A closed - loop servo control system, composed of an electrical controller, servo valve, load cell, displacement sensor, extensometer, and a computer, precisely controls the test process automatically. It can accurately measure test parameters such as force, displacement, and deformation.
This testing machine is mainly used for the tensile testing of metal materials, including steel bars and steel plates. It can implement control processes like constant - rate loading, constant - rate deformation, and constant - rate displacement, and achieve three - stage control of force, deformation, and displacement in a single test with smooth transitions between them.
The computer and measurement - control system collect test data, send control commands, automatically control the test process, and calculate test results. The test curves and results are displayed in real - time on the microcomputer screen and can be printed as reports and curves by the printer. The system also has a return function, allowing the loading cylinder piston to return to the initial position automatically or manually after the test.
When it comes to testing steel bars and steel plates, the WAW - J series complies with international standards such as ISO 6892 - 1 for metallic materials - tensile testing at room temperature, ensuring reliable and comparable test results. Ideal for steel plants, this machine from HST Group will surely become an indispensable tool in material testing.
