Purpose and basic parameters of PBH section bending machine
PBH Series Section Bending Machine is a three-roller profile bending machine (aka, Angle Roll, Angle Ring Roller) with an arc-down type, which is a general equipment specially used for profile bending. It can be used to roll profiles into circular, curved, spiral and other workpieces, widely used in petroleum, chemical, shipbuilding, hydropower, metal structure, and machinery manufacturing industries.

Overview of the structure and performance of the PBH section rolling machine
Overview of the structure
The PBH Section Bending Machine is a double-pinch 3-roll bending machine. In the shape of the machine (see Figure 1), the body is welded with a steel plate.
Important notes: All the PBH section bending machines we produce can be installed both in horizontal and vertical positions.
Rotation Transmission Mechanism of PBH Section Bending Machine
The main roller performs a rotary motion by the power transmitted by the hydraulic motor, the gear, and the sprocket. The two side rollers can move in an arc around the central shaft. The power transmitted by the hydraulic motor and the gears is rotated simultaneously with the main shaft. The support rollers are mounted on both sides of the side rollers so that the support rollers can do arc motion with the side rollers. Lifting movements can be made through the respective lifting cylinders. Transmission diagram (see Figure 2).
Performance of PBH series angle rolls
The three rollers of the section bending machine are all driving rollers. The end of the profile can be pre-bent during angle rolling, and the distortion of the profile during angle rolling can be corrected by adjusting the guide roll. All of the above movements are achieved by button operations on the electrical control cabinet.
Note: During the angle rolling process, the rotary motion of the three rollers and the lifting movement of the side rollers cannot be performed at the same time to avoid malfunction. After the three rollers are installed, the side rollers can be lifted and moved. After the mold of three rollers is installed, the side rollers can be raised and lowered.
Pre-bending and bending of the machine
Operations can be divided into symmetrical bending and asymmetric bending (Figure 2):
