Repeated bending test machine for steel bars

This test machine is a process equipment for cold bending tests and plane reverse bending tests on steel bars. Its main parameters comply with the relevant provisions in GB/T1499.2-2007 "Steel for Reinforced Concrete Part 2: Hot Rolled Ribbed Reinforced Bars" and YB/T5126-2003 "Test Methods for Bending and Reverse Bending of Reinforced Concrete". It can be widely used in enterprises such as steel metallurgy, steel frame structure, prefabricated components, construction materials, steel bar production, and quality supervision institutes, engineering quality inspection stations, scientific research institutes, colleges and universities. It is an ideal test equipment indispensable for inspecting the cold bending and reverse bending performance of threaded steel bars.

The test machine is composed of a frame, a workbench, a working plate, a reducer, a compression device, an electrical control box, a safety shield and a bending accessories. It has the characteristics of compact structure, simple operation, large load-bearing capacity, stable operation, low noise, and intuitive bending angle display, safe and reliable, and easy maintenance. In order to ensure the safety of operators and equipment, the test machine is also equipped with a reliable limiting mechanism, and the equipment can be stopped in time when the electrical control part is out of control or operated.
