This series of bending testing machine is designed with 3-cylinder structure, allowing fast and freely adjusting the span and fulfilling 180 degree bend test. It is widely used for bending test of metallic materials. It provides with constant loading rate and constant displacement rate control, able to switch from one to the other. This equipment is widely used in steel industries, quality lab, research institutes, universities and etc.
One upper-positioned cylinder applies the force to bend specimen to preset angle, then two opposite horizontal-placed cylinders bend the specimen to required angle. It can satisfy precise 180 degree bending test with high efficiency and easy-to-operate.
l One-body cast steel structure with high stiffness
l 3-cylinder design to perform any angle bending test
l Compact structure with ergonomic design
l Two horizontal-positioned cylinders are controlled by highly precise synchronous valve with error less than 2%
l Easily switch between automatic and manual bending test
l Force measurement is guaranteed by high accuracy load cell, with high reliability and repeatability
l Displacement is measured by photoelectric encoder with high accuracy and stability
l Self-calibration: force and displacement can be calibrated automatically according to test standards
l Silent HPU features environmental-friendly and humanized design. Unique pressure differential follow-up system allows low energy consumption and low heat generation
l High speed DSP control electronics provides high integrity, strong control and data processing ability, and high reliability
l Closed loop control and measurement of stress, strain and displacement. Control loops can switch automatically and smoothly. Control algorithm adopts advanced neural element self-adapting PID.
l New developed controller provides 1/500000 resolution with non-step in full range.
l Built-in overload protection both in hardware and software
