全自动型液压中频弯管机设有机械部分和电器控制部分。

中频弯管机机械部分设有4大机构分别为动力源机构、夹紧固定机构、弯管弯曲半径调节机械、推进机构。

中频弯管机电器部分由2大系统组成分别为加热系统和PLC控制系统 。
中频弯管机PLC控制系统：采用西门子S7-200,利用工控机或触摸屏,根据弯管工艺，从94年开发研制一套自动控制系统：——即将所需弯管的几何尺寸、弯曲半径、弯管角度及原材料的编号、材质、煨制时所需要温度等一系列数据输入计算机，让计算机根据这些数据来自动跟踪控制，完成煨管操作过程.
①、中频弯管机采用远红外测温仪一点或几点采样，一点确保温升可靠，过程中明确显示，随时监控温升情况。
②、中频弯管机自动跟踪控制：实现网电压高，温升相应快，而液压推进速度快；网电压低，温升慢，液压推进速度自动慢，形成闭环，保持相对平衡。
③、中频弯管机弯管煨制过程：计算机随时记录弯管煨制情况。当一根弯管煨制角度到位时，计算机自动停机报警，整个煨制过程的数据和图像可存储打印。

Automatic type hydraulic if pipe bender is equipped with mechanical part and electric controlling part. Mechanical part has four institutions: Power supply mechanism, clamp fixed institution, bend radius adjusting mechanism, feed mechanism.

Electrical part of If pipe bending machine consists of two systems: Heating system and PLC control system.
PLC control systemof If pipe bending machine :

The Siemens S7-200, using the industrial computer or touch screen , We developed a set of automatic control system from year 1994 according to the bending process : - Put the required bend geometry size, bending radius, bend Angle and raw material Numbers, material, heating required temperature and a series of data into the computer, let the computer has automatic tracking control according to those data, complete the tube bending process .
1. Using far infrared thermometer of IF  pipe bending machine , sampling with one point or multiple point, One point ensure reliable temperature rise, process clear display and monitoring temperature rise situation all times.
2. Automatic tracking control of if  pipe bending machine  : To realize that when high voltage in network, temperature quick rise correspondingly, so achieve fast hydraulic pushing speed; If low voltage in network, temperature rise is slow, hydraulic pushing speed is slow correspondingly, Forming closed cycle, keep relative balance.
3. Pipe bending process of if  pipe bending machine : The computer records pipe bending situation at all times. When bending angel of the pipe arrived in required place, the computer stop and alarm automatically, the whole data and image of bending process can be stored and printed.

The elbow forming machine canmake elbow size upto Φ1420mm .
