Abstract
The invention discloses a pipe bending process adopting an internal supporting method and a special internal supporting bag. The pipe bending process comprises the following steps: firstly, placing the special internal supporting bag into a part of a pipe, which is to be bent; secondly, introducing pressure fluid into a rubber bag of the special internal supporting bag to enable the rubber bag to support the inner wall of the pipe; thirdly, bending the pipe to form; and fourthly, enabling the pipe to release the pressure and taking out the internal supporting bag from the pipe. The special internal supporting bag comprises the rubber bag, a bag mouth, a baffle and a nut. The pipe bending process adopting the internal supporting method and the special internal supporting bag, which are disclosed by the invention, are mainly used for bending processing of thin-wall steel tubes and have the advantages that the process is simple and feasible; the internal supporting bag is simple in structure and convenient to manufacture; and uncontrollable deformation of the bent part when the thin-wall steel tube is bent can be effectively avoided. According to the pipe bending process and the special internal supporting bag, the problem that the uncontrollable deformation at the bent position occurs when the thin-wall steel tube is bent by using a traditional steel tube bending process is solved.
