[0002] A press brake is a widely used piece of equipment in sheet metal processing. It is able to bend thin sheets into the desired shape.

[0004] After analysis, it was found that the die head and support wheel of the pipe bending machine have fixed sizes. When processing large-diameter metal pipes, since the diameter of the metal pipe is larger than the inner diameter of the arc-shaped groove of the die head and the support wheel, it is difficult to effectively support the metal pipe and subsequent bending processing cannot be utilized.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In one embodiment, Figure 1-Figure 8 As shown, a pipe bending machine with an adjustment mechanism includes an operating table 1 and a U-shaped plate 3 and a fixed seat 4 arranged at the upper end of the operating table 1. The upper end of the operating table 1 is fixedly connected to a cylinder 2, and the output end of the cylinder 2 is connected to the U-shaped plate 3. The cylinder 2 is started to push the U-shaped plate 3 to move. The U-shaped plate 3 is connected to two groups of bending frames 5. The middle part of the front end of the two groups of bending frames 5 is connected to an extrusion column 501. The extrusion column 501 is rotatably connected to the bending frame 5 through a bearing. The U-shaped plate 3 drives the bending frame 5 and the extrusion column 501 to move. A circular hole is opened in the middle of the fixed seat 4 and cooperates with the circular hole A sleeve 401 is provided, and sliding holes 402 are opened on both sides of the sleeve 401. A threaded rod 403 is provided in the sleeve 401, and the threaded rod 403 is rotatably connected to the operating table 1 through a bearing. The sleeve 401 is slidably connected to a movable seat 404 along the sliding hole 402, and the movable seat 404 is threadedly connected to the threaded rod 403. By rotating the threaded rod 403, the movable seat 404 can be driven to move up and down along the sliding hole on the sleeve 401. The distance between the fixed seat 4 and the movable seat 404 can be adjusted according to different pipe diameters, so as to facilitate the processing of metal pipes of different sizes.

[0027] like Figure 1 and Figure 8 As shown, a screw rod 502 is provided on the inner side of the U-shaped plate 3, and two sets of opposite threads are provided on the screw rod 502. The screw rod 502 is threadedly connected to the two sets of bending frames 5. The screw rod 502 is connected to the operating table 1 through the bracket 503. When processing a metal pipe with a large diameter, the screw rod 502 can be rotated to adjust the distance between the bending frames 5. When the distance between the bending frames 5 increases, the large diameter metal pipe can be bent more easily.

[0028] like Figure 7 and Figure 8 As shown, a guide groove 101 is provided on the operating table 1, and a slider is provided on the U-shaped plate 3 to match the guide groove 101, so as to prevent the U-shaped plate 3 from deflecting when moving.

[0029] The above embodiment discloses a pipe bending machine with an adjustment mechanism, wherein the distance between the fixed seat 4 and the movable seat 404 is adjusted according to the diameter of the metal pipe to be processed. Specifically, the threaded rod 403 is rotated to drive the movable seat 404 to slide up and down along the sliding hole 402 on the sleeve 401, thereby adjusting the distance, placing the metal pipe to be bent between the fixed seat 4 and the movable seat 404, starting the cylinder 2 to push the bending frame 5 to move, and the extrusion column 501 contacts and bends the metal pipe to complete the processing.

[0030] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
