The steel bar bending test machine is a specialized equipment used to test the plastic deformation capacity and bending resistance of steel bars (or other metal materials) under bending loads. It is widely used in construction, metallurgy, quality inspection and other fields to ensure that steel bars comply with national standards (such as GB/T 1499, ISO 6892, etc.).
1. Main functions
Cold bending test: Evaluate the bending performance of steel bars at room temperature (such as whether they crack after bending at 180 ° or 90 °).
Repeated bending test: testing the durability of steel bars after multiple bending tests (such as GB/T 238 standard). Process adaptability: Verify the bendability of steel bars during processing (such as the production
of stirrups).
2. Core structure composition
Loading method: Apply bending force by manually or electrically driving the worm gear.
Pressure head (bend center): Bend center molds with different diameters, matched with steel bar specifications (such as bend center diameter=2d, 3d, where d is the nominal diameter of the steel bar).
Support roller: Fix both ends of the steel bar to ensure accurate bending center position.
Control system: manual operation (traditional equipment) or PLC automatic control (modern equipment, can preset bending angle and speed).
Measurement system: angle sensor (real-time display of bending angle, accuracy ± 1 °). Digital display screen (recording parameters such as load and bending times).
