Profiles are widely used steel material structures. The standardization, standardization and serialization of profiles not only saves producers a lot of time, financial resources, and material resources to reduce costs and achieve good economic benefits, but also facilitates the use requirements of consumers.

Profiles have various specifications. According to the performance requirements, commonly used profiles include angle steel, channel steel, I-beam, flat steel, round steel, etc. Generally, they are first extruded and formed by special molds, and then processed and formed again by professional equipment such as profile bending machines through bending, stamping and other processes.

The structure of the profile bending machine is an arc downward adjustment structure. The upper roller is fixed, and the two lower rollers are respectively moved up and down in an arc relative to the upper roller around a central axis. Its main function is to pre-bend the end of the profile and bend and deform the profile. At the same time, the two lower rollers are also the main transmission shafts, driven by hydraulic motors, so that the bent and deformed profiles are rolled into shape.

The entire profile bending machine is hydraulically driven, and the lifting and lowering movements of the two lower rollers are centrally controlled by electricity. The digital display is concentrated on the operation table. In order to prevent the profile from twisting and deforming during the bending process and improve the bending accuracy of the profile, two rollers and wheels are added, which can move up and down vertically to adapt to the bending of profiles of different specifications and different bending radius.

1. After the equipment is started, it will run idle for 1-2 minutes, and the upper slide will move 2-3 times at full stroke. If abnormal sound or fault is found, it should be stopped immediately, and the fault should be eliminated. It can only work after everything is normal;

2. When the upper slide and each positioning axis are not at the origin, run the return to origin program;

3. When the processed objects are loaded and unloaded on the rack, there should be a special person to command. The wind top switch can be started only when the command is heard, and the objects should be placed neatly according to the fixed management requirements and placed flat and firmly;

4. When the bending degree is large, people are not allowed to stand at the end.

The profile bending machine is a special and efficient processing equipment for bending various special-shaped materials such as angle steel, channel steel, I-beam, flat steel, square tube, round tube, etc. It can complete the pre-bending, rolling and rounding processes of various types of profiles in one loading. This equipment is widely used in aerospace, petrochemical, hydropower, shipbuilding, automobile manufacturing, machinery manufacturing, steel structure construction and other industries.
