BLMA: Main Difference Between 2D Pipe Bender and 3D Pipe Bender
2019-11-01

Due to the different industry users of various CNC pipe bending machines, the process objects are not the same. The CNC pipe bending machine is mainly constructed in three ways:


A. Directly adopt embedded CNC system. The advantage is that programming is convinient, and it can be used according to different pipe bending requests, without excessive mechanical intervention, and the program can be used to complete the work, but the programming quality requirements for the personnel are relatively high. Ordinary models do not support the input of elbow XYZ geometric coordinate data.


B. Control mode separated by programmable controller PLC, position/speed control unit, touch screen and AC servo drive unit. PLC ladder diagram, STL programming control the organic separation of the position/speed unit and the touch screen, directly input the bending process data, and support the conversion of the elbow XYZ geometric coordinate data to the elbow YBC processing data. PLC hardware has high reliability, strong anti-interference, easy to maintain and re-develop software of pipe bender.


C. Industrial grade computer, servo motion control board, AC servo unit, system software is completed by C language or VB visual program, which can make full use of computer resources diversity and functionality, can be used for complex motion processes, mechanical trajectories, etc. Applications such as complex mechanical structures. In addition to the functions of the second method, it also increases the utility of pipe processing machinery intervention. The reliability of the hardware is slightly lower than that of the PLC system. It adopts the control mode of PLC, position/speed control unit, touch screen and AC servo drive unit. The designed pipe bending machine system has two modes: manual and automatic operation. In the automatic mode, it can be divided into step-following bending and origin-string bending, which is convenient for processing a variety of complicated pipe fittings.


Regarding the pipe fittings with different bending radius, the upper and lower die switching is used to complete the processing of the pipe bending operation. For the bending of the pipe fittings for special machining requests, actions such as linkage, synthesis and corresponding auxiliary pushing are designed to prevent mechanical intervention and complete the automation of the pipe bending process. The automatic CNC bending machine cooperates with the automatic loading and unloading machine to realize unmanned automatic production, realizing automatic production in the true sense, automatic equipment has low dependence on people, realizes intelligent production, and information exchange is compatible, workshop and office. The leadership layer is well aware of the entire production process and the product quality has further leap.


BLMA can make customized pipe processing machinery which is more suitable for clients’ requirement. To meet the needs of each industry, the machine is more humane, the service is more humanized, in order to repay the society's love for us.
