Pipe bending machine

Pipe bending machine

Heating pipe bending unit is the key manufacturing equipment for the construction of oil and gas pipelines by heating the steel pipe locally and applying torque to produce the elbow products required by the pipeline.The development of national economy has an increasing demand for energy, and oil and gas pipelines, especially national key pipeline projects, are in urgent need of high capacity pipe fittings.High capacity pipe fittings have large diameter and high pressure resistance, so that the pipe bending unit has large load and high technological requirements. In order to process the elbow products in such pipe fittings, it is necessary to accurately control the processing speed, temperature, Angle, pre-deformation amount of pipe fittings and other parameters.Aiming at these requirements, a set of digital control system of large caliber medium frequency heating pipe bending unit is researched and developed.The control system can collect, control and record machining parameters in real time, which has a high level of automation and information.The current main problems of pipe bending unit control system, analyzes the working process of the large diameter medium frequency heating pipe bending machine and the function of the control system, adopting field bus technology of digital control system, solved the tailstock speed control, the heating power control, the heating temperature distribution control, bending Angle control and deformation control of the difficult problems such as pipe fittings.After the system is put into actual production, the operation condition is good, and the performance and process parameters meet the design requirements.It has been used in key national projects such as Sichuan gas transmission to the east, and provided technical support for the construction of the second line of West-East gas transmission, China and Russia, Central Asia and other large pipelines. It has become an indispensable supporting equipment in the construction of large-scale energy transmission pipelines in China, and achieved good social benefits.

The PLC-controlled medium frequency pipe bender produced by Aoguang Mechanical Equipment Co., Ltd. can realize the automation of bending process.Pipe fitting of medium frequency pipe bender can bend round pipe and rectangular pipe mechanically.The medium frequency pipe bender can bend both S and U bends.The medium frequency pipe bender is stable in performance and reliable in quality, which is well received by new and old customers.
