[0002] Straightening machines are equipment for straightening metal profiles, bars, pipes, wires, etc. Straightening machines use the concave surface of the straightening roller to squeeze the bars to change their straightness. Generally, there are two rows of straightening rollers, with varying numbers.

[0003] However, the sizes of tubes and bars vary, which makes it difficult for one straightening machine to adapt to the straightening of tubes and bars of different sizes.

[0004] Therefore, it is necessary to provide a roller system device for a metal tube and bar precision straightening machine to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a roller system device for a precision straightening machine for metal tubes and bars, so as to achieve the effect of adapting to metal tubes and bars of different sizes.

[0006] The technical solution adopted by the present application to solve its technical problems is: a roller system device of a precision straightening machine for metal tubes and bars, including a support table, a rotating table is rotatably arranged on one side of the support table, support plates are fixed on both sides of the rotating table away from one end of the support table, a straightening roller is rotatably connected between the two support plates, the straightening roller has a concave arc surface in the circumference, an extension rod is fixed on one side of the rotating table, two fixed plates are arranged on the end of the extension rod away from the rotating table, a containing box is fixed on one side of the support table, a moving block is arranged between the two ends inside the containing box, an adjusting rod is fixed on one side of the moving block, the end of the adjusting rod away from the moving block is located between two clamping plates, and the moving block is suitable for moving between the two ends of the containing box.

[0007] Furthermore, a threaded shaft is rotatably connected between the two ends inside the containing box, and the threaded shaft is threadedly connected to the moving block.

[0008] Furthermore, a slide rail is fixed to one end of the extension rod away from the rotating platform, and sliders are slidably connected to both sides of the slide rail, and the sliders are respectively fixed to a clamping plate.

[0009] Furthermore, fixed plates are fixed at both ends of the slide rail, the clamping plate is located between the two fixed plates, guide rods are fixed on the opposite sides of the two clamping plates, the guide rods respectively penetrate the fixed plates on one side, and an elastic member is arranged between the clamping plate and the fixed plate.

[0010] Furthermore, it also includes a base, a top platform is arranged on the upper side of the base, a plurality of guide shafts are connected between the base and the top platform, the support platform is distributed on the upper side of the base and the lower side of the top platform, and both ends of the support platform are slidably connected to a guide shaft respectively.

[0011] The beneficial effects of the utility model are:

[0012] By moving the moving block, the adjusting rod is driven to push the clamping plate to rotate the turntable. Since the circumference of the straightening roller is a concave arc surface, when the turntable rotates, the angle of the straightening roller will change. At this time, the size of the concave arc surface of the straightening roller facing the two ends of the straightening machine will change, so that the straightening roller can straighten pipes and bars of different sizes.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0022] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0023] like Figure 1-3 As shown, the present application provides a roller system device for a precision straightening machine for metal tubes and bars, comprising a base 1, a top platform 11 is arranged on the upper side of the base 1, and a plurality of guide shafts 12 are connected between the base 1 and the top platform 11.

[0024] Several support platforms 2 (only one group is shown in the figure) are arranged on the upper side of the base 1 and the lower side of the top platform 11. The two ends of the support platforms 2 are slidably connected to a guide shaft 12 respectively. The support platforms 2 on the upper side of the base 1 correspond to the support platforms 2 on the lower side of the top platform 11.

[0025] A rotating table 21 is rotatably provided on one side opposite to the support table 2. Support plates 211 are fixed on both sides of the rotating table 21 away from one end of the support table 2. A straightening roller 212 is rotatably connected between the two support plates 211. The circumference of the straightening roller 212 is a concave arc surface.

[0026] An extension rod 22 is fixed to one side of the rotating table 21. A slide rail 221 is fixed to one end of the extension rod 22 away from the rotating table 21. A fixing plate 222 is fixed to both ends of the slide rail 221. A slider 223 is provided on one side of the fixing plate 222 close to the slide rail 221. The slider 223 is slidably connected to the slide rail 221. A clamping plate 224 is fixed to the side of the slider 223 away from the rotating table 21. A guide rod 225 is fixed to the opposite side of the two clamping plates 224. The guide rod 225 passes through the fixing plate 222 on one side. An elastic member 226 is provided between the clamping plate 224 and the fixing plate 222. In this embodiment, the elastic member 226 is a spring. The elastic member 226 is sleeved on the guide rod 225.

[0027] A accommodating box 23 is fixed on one side of the support platform 2, a threaded shaft 231 is rotatably connected between the two ends inside the accommodating box 23, a moving block 232 is threadedly connected to the threaded shaft 231, an adjusting rod 233 is fixed on one side of the moving block 232, and the end of the adjusting rod 233 away from the moving block 232 is located between the two clamping plates 224.

[0028] Since the accommodating box 23 is fixed on one side of the supporting platform 2, it is convenient for an external driving device (not shown) to be connected to one end of all the threaded shafts 231 through a connecting shaft, so that all the threaded shafts 231 are driven by the same driving device, thereby allowing all the threaded shafts 231 to rotate synchronously.

[0029] Since the threaded shaft 231 is threadedly connected with the moving block 232, when the threaded shaft 231 rotates, the moving block 232 will move along the threaded shaft 231, thereby driving the adjusting rod 233 to push the clamping plate 224, so that the rotating table 21 rotates. Since the circumferential direction of the straightening roller 212 is a concave arc surface, when the rotating table 21 rotates, the angle of the straightening roller 212 will change, and the size of the concave arc surface of the straightening roller 212 facing the two ends of the straightening machine will change, so that the straightening roller 212 can straighten pipes and bars of different sizes.

[0030] The elastic member 226 will push the clamping plate 224 through its own elasticity, so that the two clamping plates 224 are close to each other along the slide rail 221, and the two clamping plates 224 are kept in a state of clamping the end of the adjusting rod 233 away from the moving block 232, thereby avoiding the occurrence of a gap between the clamping plate 224 and the adjusting rod 233 after the rotating table 21 rotates, and ensuring that the straightening roller 212 will not shake after the angle of the straightening roller 212 is changed, thereby causing inaccurate angle adjustment of the straightening roller 212.
