[0002] Currently, in my country's metal forming and stamping processing field, it is often necessary to bend round steel and round tubes. For example, patent CN212633934U discloses a simple metal tube bending device, including a worktable with supporting legs underneath. At least one set of parallel slides is fixedly installed at the top of the worktable, with adjustable sliders slidably installed at both ends of each slide. A sliding plate is fixedly connected between two adjustable sliders located at the same end within the same set, and a locking bolt is threaded through the sliding plate. A pipe support device is fixedly connected to the upper end of the sliding plate. Support columns are fixedly installed on both sides of the worktable, and a support crossbar is fixedly installed between the two support columns. A pipe bending drive device is detachably installed through the support plate. The pipe bending drive device is correspondingly set with the pipe support device, and the bottom end of the pipe bending drive device is connected to a bending head. The pipe support device includes support seats that are fixedly connected to both ends of the slide plate. A support shaft is provided through the two support seats, and a pipe support wheel is rotatably installed on the support shaft. The circumferential surface of the pipe support wheel is provided with an arc-shaped pipe support groove. However, the support wheel can only be used for round pipes of a certain diameter. When processing metal pipes of different shapes, such as square pipes, the support wheel needs to be replaced, which is inconvenient to use. Utility Model Content

Next, adjust the position of the first support component 20 and the O point of the indicator bar 17, and the position of the second support component 30 and the O point of the indicator bar 17 according to the shape of the bent metal tube. During adjustment, slide the first slide block 24 onto the first guide rail 13 until the indicator number of the first slide block 24 corresponds to the value specified by the indicator bar 17. Under the action of the first support shaft 21, the first support 25 slides synchronously onto the second guide rail 14. Then, fix the position of the first slide block 24 and the first guide rail 13 with the first positioning component 26, and fix the position of the first support 25 and the second guide rail 14 with the second positioning component. Similarly, adjust the position of the second slide block 33. Then, the metal tube is placed on the first support shaft 21 and the second support shaft 31. At this time, the first limiting wheel 22 and the first adjusting wheel 23 respectively abut against the two sides of the metal tube, and the second limiting wheel 32 and the second adjusting wheel respectively abut against the two sides of the metal tube to prevent the metal tube from shifting when it is bent. Next, the lifting power element 43 drives the lifting plate 41 to slide along the first slide rail 15 and the second slide rail 16, thereby driving the pressure roller 42 to press down in the direction of the metal tube.

This device is suitable for square tubes of different widths and round tubes of different diameters, and has a wide range of applications.

[0031] The metal tube forming device 100 of this utility model defines the two sides of the metal tube by means of the cooperation of the first limiting wheel 22 and the first adjusting wheel 23, and the second limiting wheel 32 and the second adjusting wheel. The first adjusting wheel 23 is slidably mounted on the first support shaft 21, thereby adjusting the distance between the first adjusting wheel 23 and the first limiting wheel 22; the second adjusting wheel is slidably mounted on the second support shaft 31, thereby adjusting the distance between the second adjusting wheel and the second limiting wheel 32, thus adapting to metal tubes of different sizes and being convenient to use.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
