The new standard steel bar bending test machine adopts hydraulic power source drive, which consists of three parts: test host, oil source (hydraulic power source), and standard bending head, with a test force of 300kN.

This steel bar bending testing machine is used for bending tests of metal materials such as bars, plates, and threaded steel for construction. The testing machine adopts a bidirectional hydraulic cylinder loading, adjusts the spacing between the support rollers through a handwheel, and can self lock.

Characteristics of vertical steel bar forward and reverse bending testing machine:

1. The steel bar bending testing machine is a four column frame structure, with the main oil cylinder placed on top. The main structure consists of oil source, chassis, oil cylinder, piston, wheel support roller assembly, light bar, upper crossbeam and other components.

2. The steel bar bending testing machine adopts a high sealing bidirectional oil cylinder and has strong durability.

3. The design of the steel bar bending testing machine takes into full consideration aesthetics, convenience, and safety. For example, the main structural components are made of ductile iron, which has strong rigidity and good stability; The height of the workbench is 800mm for easy access and placement of test specimens; A high resilience protective net is installed above the platform to create isolation between the testing space and the operator, effectively ensuring the safety of the operator; The surface of the light bar is chrome plated and polished, with high hardness, beautiful appearance, and rust prevention;

4. The spacing between the support rollers is adjusted by shaking the handwheel to drive the screw. After adjusting the spacing, the support rollers are self-locking without the need for fastening, making it easy to operate and greatly reducing labor intensity.

5. The bending indenter is a supporting product designed for the standard GB/T232-2010 "Bending Test Method for Metallic Materials". This product is a necessary tool for steel bar bending tests, and the replacement method is insertion type operation, which is convenient.
