[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 As shown, a stainless steel pipe straightening machine includes a mechanism bin 1, a mechanism body 2 is fixedly connected to the front end of the mechanism bin 1, a protective cover 3 is fixedly connected to the front side of the mechanism body 2, a water outlet 4 is fixedly connected to the middle of the rear side of the mechanism bin 1 near the bottom, a cleaning mechanism 5 is fixedly connected to the inner side of the mechanism body 2, and a plurality of linearly distributed correction mechanisms 6 are fixedly connected to the inner side of the mechanism bin 1.

[0027] It should be noted that the inner cavities of the mechanism body 2 and the bottom wall of the mechanism bin 1 are interconnected, and the water consumed by the cleaning mechanism 5 enters the inner cavities of the mechanism body 2 and the bottom wall of the mechanism bin 1 and is discharged through the water outlet 4.

[0028] like Figure 2 , Figure 4As shown, the cleaning mechanism 5 includes a first motor 51, the lower surface of the first motor 51 is fixedly connected to the lower surface of the inner cavity of the side wall of the mechanism body 2 near the left side, the output end of the first motor 51 is fixedly connected to a gear 52, a rotating ring 53 is rotatably connected to the middle part of the inner wall of the mechanism body 2, the outer wall of the rotating ring 53 is fixedly connected to a gear ring 54, and the lower left side of the gear ring 54 is meshed and connected with the upper right side of the gear 52.

[0029] It should be noted that the first motor 51 drives the gear 52 to rotate, the gear 52 drives the ring gear 54 to rotate, and when the ring gear 54 rotates, it drives the rotating ring 53 to rotate.

[0030] like Figure 3 , Figure 4 As shown, the inner wall of the rotating circle 53 is fixedly connected with four cleaning components 55 distributed in an annular manner, and the four cleaning components 55 each include a telescopic rod 551, the outer end of the telescopic rod 551 is fixedly connected to the inner side of the rotating circle 53, one end of the telescopic rod 551 close to the axis of the rotating circle 53 is fixedly connected to a rotating table 552, the outer wall of the rotating table 552 is movably sleeved with a spring 553, and the inner side of the rotating table 552 is rotatably connected with a cleaning wheel 554.

[0031] It should be noted that when the steel pipe passes through the cleaning wheel 554, the cleaning wheel 554 is driven to rotate through friction, so that the cleaning wheel 554 cleans the outer wall of the steel pipe. The spring 553 pushes the rotating table 552, so that the gap between the cleaning wheels 554 can adapt to steel pipes of various specifications and thicknesses.

[0032] like Figure 3 As shown, a water spray circle 56 is fixedly connected to the inner side of the mechanism body 2 near the front side, and two water flow plates 58 distributed front and back are embedded in the inner side of the mechanism body 2 near the lower side, and the two water flow plates 58 are located on the front and rear sides of the rotating circle 53.

[0033] It should be noted that the water spray ring 56 is used to spray water to moisten the outer wall of the steel pipe to facilitate the cleaning operation of the cleaning wheel 554, and the excess water flows from the water flow plate 58 into the inner cavity of the bottom wall of the mechanism body 2 and the mechanism compartment 1.

[0034] like Figure 3 As shown, a heating coil 57 is fixedly connected to the inner side of the mechanism body 2 near the rear side.

[0035] It should be noted that the heating ring 57 heats the steel pipe to evaporate the water on the outer wall of the steel pipe. At the same time, the temperature increase of the steel pipe can facilitate the straightening operation of the steel pipe.

[0036] like Figure 2 , Figure 5As shown, several correction mechanisms 6 include a rotating table 61, and one side of the rotating table 61 close to the inner wall of the mechanism bin 1 is rotatably connected to the inner wall of the mechanism bin 1, and two rotating tables 61 are distributed in a ring, and the ends of the two rotating tables 61 close to each other are fixedly connected to a hydraulic rod 62, and the ends of the two hydraulic rods 62 close to each other are fixedly connected to a base plate 63, and the positions of the sides of the two base plates 63 close to each other near the edges are fixedly connected to a second motor 64, and the output ends of the two second motors 64 are rotatably connected to a rotating roller 65.

[0037] It should be noted that the rotating table 61 contains a rotating component, which can rotate on the inner wall of the mechanism bin 1. Two adjacent rotating rollers 65 on the same horizontal vertical plane are arranged crosswise. The hydraulic rod 62 drives the base plate 63 to move axially to adjust the distance between the two rotating rollers 65. The second motor 64 drives the rotating roller 65 to rotate to straighten the steel pipe.

[0038] like Figure 2 , Figure 5 As shown, the two rotating tables 61 at odd positions from front to back are distributed up and down, and the two rotating tables 61 at even positions from front to back are distributed left to right.

[0039] It should be noted that the rotating rollers 65 distributed vertically correct the twisting of the steel pipe in the vertical direction, and the rotating rollers 65 distributed horizontally correct the twisting of the steel pipe in the horizontal direction.

[0040] like Figure 1 As shown, the shield 3 is conical in shape, and the diameter of the front end is smaller than that of the rear end.

[0041] It should be noted that the shape of the shield 3 is such that when the water spraying circle 56 is performing a water spraying operation, excess water will be blocked by the shield 3, thereby preventing water from flowing out from the front side of the straightener and keeping the front side environment of the straightener dry.

[0042] The working principle of the utility model is as follows: first, the rotating table 61 contains a rotating assembly, which can rotate on the inner wall of the mechanism bin 1. Two adjacent rotating rollers 65 on the same horizontal vertical plane are arranged crosswise. The hydraulic rod 62 drives the base plate 63 to move axially to adjust the distance between the two rotating rollers 65. The second motor 64 drives the rotating rollers 65 to rotate to straighten the steel pipe. The rotating rollers 65 distributed up and down correct the distortion of the steel pipe in the up and down directions, and the rotating rollers 65 distributed left and right correct the distortion of the steel pipe in the left and right directions. The steel pipe passes through the heating ring 57 and then enters the position between the two adjacent rotating rollers 65. The two rotating rollers 65 in the up and down directions correct the upper and lower sides of the steel pipe, and the two rotating rollers 65 in the left and right directions correct the sideways of the steel pipe. Compared with the one-way correction of the transmission, one more is added. dimension, so that the correction effect is better. Finally, the first motor 51 drives the gear 52 to rotate, the gear 52 drives the ring gear 54 to rotate, and the ring gear 54 drives the rotating ring 53 to rotate when it rotates. When the steel pipe passes through the cleaning wheel 554, the cleaning wheel 554 is driven to rotate by friction, so that the cleaning wheel 554 cleans the outer wall of the steel pipe. The spring 553 pushes the rotating table 552, so that the gap between the cleaning wheels 554 can adapt to steel pipes of various specifications and thicknesses. The water spraying circle 56 is used to spray water to moisten the outer wall of the steel pipe to facilitate the cleaning operation of the cleaning wheel 554. Excess water flows from the water passing plate 58 into the inner cavity of the bottom wall of the mechanism body 2 and the mechanism bin 1, and water is sprayed to the outer wall of the steel pipe through the water spraying circle 56. The cleaning wheel 554 cleans its outer wall, so that the dirt on the outer wall of the steel pipe is removed before the straightening operation is performed, thereby preventing various dirt from affecting the correction operation.
