Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a hydraulic pipe bending machine. Background Art

[0002] The pipe bending machine is mainly based on the principle of vector pipe bending and uses microcomputer control to complete any spatial three-dimensional pipe shape required by the user. It is an important processing equipment for modern bending and shaping. During processing, it is also possible to encounter pipe shapes that need to be changed, so the pipe bending machine is an indispensable mechanical equipment in modern mechanical processing.

[0003] According to the description of a hydraulic pipe bender disclosed in the patent website (authorization announcement number: CN 220371968 U), "The utility model discloses a hydraulic pipe bender, which relates to the field of pipe bender, including a base and a bending column arranged on the base, the base is also provided with a hydraulic cylinder and an extrusion part connected to the output end of the hydraulic cylinder, and the bending column is provided with a locking component for preventing the bending column from being separated from the base. The utility model provides a hydraulic pipe bender, in which a locking component is additionally provided on the bending column. When the bending column is plugged into the base, the locking component can fix the position of the bending column, and when the pipe bending operation is performed, the bending column can be prevented from bouncing, thereby reducing the safety hazard during the pipe bending operation."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During the use of the utility model, since there are multiple groups of adjustment grooves on the base, the bending column is plugged into one of the adjustment grooves. However, when the required bending angle is large, it cannot be bent into place at one time, and the position of the adjustment groove needs to be continuously adjusted to finally complete the bending, which makes the bending efficiency low. When facing larger-sized pipes, the curvature set by the bending column is fixed, which will squeeze the side of the pipe and cause deformation of the pipe. When facing smaller-sized pipes, because the curvature set by the bending column is fixed, the small-sized pipe will slide during bending. When bending, no fixing device is set on both sides, which will cause the pipe to rotate during bending, resulting in inaccurate bending angles and offset bending directions. Therefore, it is necessary to improve a hydraulic pipe bender to solve the above problems. Utility Model Content
