I-beam Cold Bending Machine

 

 

The I-beam cold bending machine is mainly used for the cold processing of steel arch frames. I-beam bending machines are primarily used for bending I-beams, channel steel, angle steel, U-shaped steel, and other profiles in tunnels, subways, hydropower stations, and underground chambers.

1. Cold-formed steel is the main material for light steel structures, made by cold-forming steel plates or strips.
2. Its wall thickness can be made very thin, and it greatly simplifies the production process and improves production efficiency.
3. The I-beam cold bending machine can produce various shapes and different materials of cold-formed steel with uniform wall thickness but complex cross-sectional shapes, which are difficult to produce using general hot-rolling methods.
4. In addition to various building structures, cold-formed steel is also used in vehicle manufacturing, agricultural machinery manufacturing, and other fields.
5. There are many types of cold-formed steel, classified by cross-section into open, semi-closed, and closed sections. By shape, there are cold-formed channel steel, angle steel, Z-shaped steel, square tubes, rectangular tubes, special-shaped tubes, and rolling doors, etc.

 

The steel is placed on the I-beam cold bending machine and comes into contact with the roller driven by the reduction gear. The pressing handle is then advanced and locked. The motor and oil pump unit are started, and the high-pressure oil from the electric oil pump passes through the overflow valve (all pressure is adjustable) into the integrated block to the solenoid valve. The electro-hydraulic valve and the jog switch (jog forward, jog backward) control the cylinder's operation. The working cylinder advances, pressing the I-beam against the three supporting rollers. The bending deformation begins to be calculated at this point. The cylinder advances in increments of 10mm-15mm. The main motor is started to drive the I-beam. This process is repeated until the desired shape is achieved.
