Technical Field
[0001] The utility model relates to the technical field of fin tube rolling, in particular to a high-speed fin tube rolling device. Background Art
[0002] Finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, thereby achieving the purpose of improving the heat exchange efficiency. The rolling of finned tube is to line copper tube or steel tube (also called base tube) with aluminum tubes of different specifications, and then roll and compound them through the cutter in the unit, and extrude the fins at one time, in order to achieve the effect of increasing the heat exchange area.

However, when rolling metal tubes of different diameters, the diameter of the metal tube is not fixed, but the position of the rolling knife of the traditional equipment cannot be moved. In this way, when rolling thinner metal tubes, the outer wall of the rolling knife cannot contact the metal tube well, and thus the metal tube cannot be rolled. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 A high-speed fin tube rolling device includes a support frame 1, a limit rod 2 is fixedly assembled on the outer wall of the support frame 1, a support ring 3 is fixedly assembled on the outer wall of the support frame 1, an adjusting ring 4 is rotatably connected to the outer wall of the support ring 3, a moving rod 5 is movably sleeved on the inner cavity of the support frame 1, a fixing plate 6 is fixedly assembled on the outer wall of the moving rod 5, a fixing frame 7 is fixedly assembled on the outer edge of the moving rod 5, and an extrusion roller 8 is rotatably connected to the inner cavity of the fixing frame 7.
[0021] By means of the fixing frame 7 and the squeezing roller 8 arranged in three directions of the inner cavity of the support frame 1, the outer wall of the squeezing roller 8 can contact the outer wall of the metal tube under the action of the fixing frame 7, so that the outer wall of the metal tube is rolled during the rotation of the squeezing roller 8, thereby preparing the metal tube into a finned tube.
[0022] In a preferred embodiment: the inner wall of the adjusting ring 4 is provided with an internal thread, and the inner wall of the adjusting ring 4 is threadedly connected to the outer wall of the moving rod 5 .
[0023] Through the internal thread opened on the inner wall of the adjusting ring 4, under the action of the internal thread of the inner wall of the adjusting ring 4, when the position of the moving rod 5 needs to be adjusted, it is only necessary to rotate the adjusting ring 4, and the position of the moving rod 5 can be adjusted under the action of the adjusting ring 4, so that the outer wall of the extrusion roller 8 can better fit the outer wall of the metal tube.
[0024] In a preferred embodiment: a limiting hole is provided on the outer wall of the fixing plate 6 , and the inner cavity of the fixing plate 6 is movably sleeved on the outer wall of the limiting rod 2 .
[0025] By setting a limit rod 2 on the outer wall of the support frame 1, and the outer wall of the fixed plate 6 is movably sleeved on the outer wall of the limit rod 2, the movable rod 5 can only move up and down along the outer wall of the limit rod 2 under the action of the fixed plate 6 and the limit rod 2. Therefore, when the height of the extrusion roller 8 needs to be adjusted, it is only necessary to rotate the adjusting ring 4, and the height of the movable rod 5 can be adjusted up and down under the action of the adjusting ring 4.
[0026] In a preferred embodiment, the outer wall of the support ring 3 is embedded in the outer wall of the adjustment ring 4 , there are three moving rods 5 , and the three moving rods 5 are respectively installed on the outer wall of the support frame 1 .
