product description
Mainframe: The machine adopt single space door type structure, all tension, compression and bending test are applied at the lower space. The loadframe is consisted of two-column, ballscrew, upper crosshead, middle crosshead and worktable, and the adjustable speed system is installed underside of the worktable. High accuracy, wide range and stable Japan Panasonic AC servo motor drive the ballscrew pair rotating through syn-deceleration system, the ballscrew pair drive middle crosshead, make the tension clamp(compression, bending) move up and down, then realize load and offload to the specimen. This structure has enough stiffness to apply high efficiency and stable moving. Key parts are processed on the processing center to ensure the accuracy of the load frame. Ballscrew is E5 class.
Standard grips: wedge tension, compression and bending clamp each one set. The wedge tension clamp adopts manual rotation clamping mode, more convenient and reliable, the grip will keep unmovable and without sliding during this process. There without any extra force is loaded on the specimen, so keep the test result is precise.
Electric part:
(1) Adopt stable and reliable Japan Panasonic AC servo driving system and servo motor, with the protection device of overcurrent, overvoltage Speeding and overload. The adjustable rate can up to 1:100000
(2) With the protection function of overload, overcurrent, overvoltage, displacement upper and lower limitation and emergency stop.
(3) The electric circuit refered to international standard and conform to national testing machine electric standard, high an excellent performance on the anti-jamming test to ensure the stability of controller and accuracy of test data.
