The existing bending equipment mainly has two modes: manual and automatic. Manual bending mainly includes the bed, angle bending die, and angle movement mechanism, which is composed of fixed movement mechanism, pipe pressing mechanism, and pipe bending mechanism. The manual mode is adopted, and the full hard steel pipe can be completed in multiple processes under manual conditions. Its disadvantages are low processing efficiency, high labor intensity, and can not meet the needs of mass production.

The full-automatic pipe bender is mainly composed of control system, mechanical part and auxiliary part. The automatic production mode is adopted. The mechanical part is mainly composed of the bed, angle bending die, angle die, fixed length movement mechanism, fixed length movement mechanism, etc. The operation is controlled by the control system. Pipe pressing mechanism and pipe bending mechanism, among which the auxiliary components are mainly displacement sensor, angle sensor and angle sensor, and the control system is mainly composed of controller. The text display is composed of a computer. The computer mainly completes the output of the bending program. The text display is mainly used to prompt the bending operation. Its control mode adopts a CNC machine tool controller, which has high working efficiency and is suitable for batch production.

However, the automatic pipe bender requires software programmer to program, and the whole machine bends the workpiece according to the programmed program. Its disadvantages are: first, the cost of the whole machine is very high; Second, it requires specialized software programming, which takes a long time and costs a lot; Third, the flexibility is poor, and it is not suitable for on-site piping.
