Automation equipment has the advantages of high efficiency, reduced labor costs, and increased labor productivity. Automated enterprises can purchase similar automation equipment to further reduce costs and take the opportunity to tide over the difficulties under the wave of China's automatic tube bending machine transformation and upgrading. At present, China's fully automatic pipe bending machine enterprises are facing a complicated international situation, and domestic competition is extremely fierce, which makes many enterprises unable to move. So what is the difference between a two-dimensional pipe bender and a three-dimensional pipe bender?
Due to the different users in various industries, the process objects and processes are also different. The construction of CNC numerical control pipe bending machine mainly adopts three methods:
A. Directly adopt embedded CNC system. The advantage is that the degree of freedom of programming is high, 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.
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 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 complex pipe fittings.
Regarding the pipe fittings with different bending radii, 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. Automatically cooperate with the automatic loading and unloading machine to realize unmanned automatic production, achieve automatic production in the true sense, low dependence of automatic equipment on people, realize intelligent production, information exchange compatibility, workshop, office, leadership, The quality of the product has been further leapfrogged by the entire production process.
