Description

[0002] When forming the hydraulic tube, the bicycle pipe fittings need to be blocked at both ends. The two ends of the hydraulic press are the water inlet cylinder and the water blocking cylinder. Currently, the two cylinders of the hydraulic press can only move in the X and Y directions. With the requirements for clearer shapes of bicycle pipe fittings and the integration of batteries and pipe motors in bicycle tubes, the production process of new pipe fittings mostly requires hydraulic forming.

[0003] Generally, the first method of making curved pipe fittings is to seal one end of the pipe fitting with a hydraulic mold for production. The disadvantage of this method is that the pipe fitting cannot be loaded with too much internal pressure, so the shape of the pipe fitting is not full, and only pipe fittings with relatively simple shapes can be made. The second method is to lead a straight auxiliary section from the elbow head. The disadvantage of this method is that it can only produce pipe fittings with smaller curvatures. When the curvature is larger, it will exceed the installation size limit of the machine.
