Abstract
Pipe bender with mid-fraquence electrica heating at home and abroad, the power system and control system can be divided into three types, a mechanical drive, which is commonly found in small diameter steel pipe bending system of small and medium-sized pipe bender with mid-fraquence electrica heating. Another pipe machine mechanical - hydraulic hybrid drive mode is generally bending power transmission by mechanical means, and drive components of the campaign to manipulate the hydraulic drive system, there is a bending power system components and drivers of all movement control system using hydraulic drive.
Medium frequency induction heating pipe is the primary means of large-scale pipe. Bending system using the law enforcing pipeline process is very important to ensure quality. Induction bending the past is entirely hand bend achieved 80 years later and gradually promote the domestic development of the Induction bending computer monitoring technology, in order to ensure the correct implementation of pipe technology provides a means of cross-monitoring. But the operation itself is still manually process consistency makes poor quality affects the stability of pipe. So induction bending process at the scene of the automatic control is an urgent need to be addressed.
Hydraulic transmission is a transmission way which is using liquid as working medium for transferring energy and controlling. This drive not only tight structure, light weight, high power output, high economy, but the machine tool has good controllable capability, and thus to realize the function what is computer aided operation.
