Steel Bar Repeated Bending Testing Machine

The steel bar repeated bending testing machine uses hydraulic or mechanical devices to repeatedly bend steel bar specimens at specified angles to evaluate their ability to withstand plastic deformation. It is used to assess the ductility and fatigue resistance of steel bars and is commonly applied in quality control of building materials and engineering acceptance processes.
Selection
Select the bending mandrel kit with corresponding bending radius based on the diameter range of the steel bar being tested; match the parameters for maximum bending angle and number of cycles; consider the compatibility of testing frequency with production efficiency; confirm that the equipment's protective devices comply with safety standards; prioritize servo motor-driven models to ensure motion accuracy.
