DETAILED DESCRIPTION

[0021] The following embodiments will be combined with the accompanying drawings to describe the utility model in detail. In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0022] See also Figure 1-5 As shown, a steel pipe straightening device proposed by the utility model includes a base 2 and a feeding mechanism 4 mounted on the top of the base 2, and a straightening mechanism 1 mounted on the top of the base 2 and located on one side of the feeding mechanism 4, the feeding mechanism 4 includes a support frame 401 fixedly mounted on the top of the base 2, a driving wheel 405 is rotatably mounted on the inner side of the support frame 401, a pressure wheel 406 is rotatably mounted on the inner side of the support frame 401 and located on the top of the driving wheel 405, the straightening mechanism 1 includes a fixed frame 101 fixedly mounted on the top of the base 2, a plurality of straightening frames 104 distributed in a circular array are slidably mounted on one side of the fixed frame 101, a plurality of rollers 105 arranged equidistantly along the length direction of the straightening frame 104 and in a circular array are rotatably mounted on the straightening frame 104, a threaded rod 106 is rotatably mounted on one side of the fixed frame 101 and located between the straightening frames 104.

[0023] Based on the above-mentioned structural setting, the steel pipe straightening device is composed of a straightening mechanism 1, a base 2 and a feeding mechanism 4, wherein, by placing the steel pipe into the feeding mechanism 4, it is convenient to perform preliminary straightening operations on the steel pipe, and at the same time, it can drive the steel pipe for transportation, so that the steel pipe can enter the straightening mechanism 1, and can extend to the inside of the steel pipe through the straightening mechanism 1, and can straighten the steel pipe from the inside by supporting it outward, and at the same time, the concave position on the steel pipe can be reset, which effectively improves the straightening effect. Specifically, in the working process, by inserting the steel pipe between the driving wheel 405 and the pressing wheel 406, the steel pipe can be driven to move by the rotation of the driving wheel 405. The pressure of the pressure wheel 406 on the steel pipe can make the steel pipe undergo preliminary correction during transportation, and the driving wheel 405 can continue to drive the steel pipe to move, so that the correction frame 104 can extend into the interior of the steel pipe. When the threaded rod 106 rotates, multiple correction frames 104 can be driven to expand and move outward, so that the roller 105 can be supported on the inner wall of the steel pipe. The roller 105 rolls on the inner wall of the steel pipe, so that the steel pipe can be supported from the inside to the outside, and the steel pipe can be corrected relatively quickly. At the same time, the depressed position on the steel pipe can be supported and reset from the inside to the outside, thereby effectively improving the correction effect of the steel pipe and the processing quality.

[0024] Furthermore, a support wheel 403 is rotatably mounted on the inner side of the support frame 401 and on one side of the driving wheel 405, and two symmetrically distributed limiting wheels 404 are rotatably mounted on one side of the support frame 401. The support wheel 403 can be used to conveniently provide rolling support when the steel pipe is being fed, so that the steel pipe can be smoothly inserted between the driving wheel 405 and the pressing wheel 406, and the limiting wheel 404 can limit the two sides of the steel pipe, so that the steel pipe will not be skewed when feeding, and can also assist in preliminary correction operations.

[0025] Furthermore, a driving mechanism 3 is fixedly installed on the top of the base 2, and the driving mechanism 3 includes a second motor 301 fixedly installed on the top of the base 2 and located on one side of the support frame 401, and the output shaft of the second motor 301 is installed with the driving wheel 405 through a belt 302. The second motor 301 can drive the driving wheel 405 to rotate by the belt 302, so that the driving wheel 405 can drive the steel pipe to perform a conveying operation.

[0026] Furthermore, a first motor 102 is fixedly installed on the other side of the fixing frame 101, and the output shaft of the first motor 102 passes through the fixing frame 101 and is fixedly connected to the threaded rod 106. The first motor 102 can provide power to the threaded rod 106, so that the threaded rod 106 can rotate.

[0027] Furthermore, the outer side of the threaded rod 106 is threadedly connected with a plurality of threaded sleeves 107 arranged equidistantly, and a movable rod 108 is hingedly installed between the threaded sleeve 107 and the correction frame 104. When the threaded rod 106 rotates, the threaded sleeve 107 can be driven to move left and right along the threaded rod 106, and the movable rod 108 can be used to push the correction frame 104 to expand outwards and move inwards, so that it can be easily adjusted according to the inner diameter of the steel pipe.

[0028] Furthermore, the fixing frame 101 and the correction frame 104 are slidably mounted via the sliding groove 103, and the support frame 401 and the base 2 are fixedly mounted via the mounting frame 402. The sliding groove 103 enables the correction frame 104 to slide stably when unfolding and closing, and the mounting frame 402 can support the feeding mechanism 4, so that the feeding mechanism 4 can stably feed and convey the steel pipe.
