Description

Technical Field

[0001] The utility model specifically relates to a transformable mounting structure for a pipe bending device. Background Art

[0002] In the metal processing industry, especially in the field of pipe processing, pipe bending forming is a common processing technology used to bend straight pipes into required shapes. Previously, the inventor of the present utility model developed a pipe bending mechanism. When this pipe bending mechanism is in use, the clamping die and the backing die approach the pipe bending die and respectively clamp and abut against the pipe fitting, and then the clamping die and the pipe bending die rotate. At this time, the bending of the pipe fitting is completed. For the specific mechanism, reference can be made to the patent solution with the patent number CN201310634656.4 and the name of a pipe bending mechanism of a pipe bender. However, this pipe bending mechanism can only bend the pipe fitting in one direction during the pipe bending process. For example, it can only bend the pipe fitting clockwise. At this time, for some new pipe fittings that need to be bent counterclockwise, if the bending law of the new pipe fitting is symmetric, the same set of pipe bending mechanism can still be used for processing. Otherwise, only a pipe bending device for counterclockwise bending or adding components to the existing equipment is needed to achieve reverse bending. Therefore, it brings problems of increased cost and inconvenient production.

[0003] The present utility model is precisely generated based on the above deficiencies. Summary of the Utility Model
