Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

Referring to the attached drawings 1-4, the utility model comprises a base 1, a straightening wheel 2, a bearing 3 and a primary and secondary screw 4. The base 1 is approximately square, the cross section is L-shaped, and the base 1 can be integrally cast by 304 stainless steel. The bearings 3 are arranged on two sides of the straightening wheels 2, so that the flexible operation of the straightening wheels 2 is ensured, and the stress of the bearings 3 can be balanced. The straightening wheels 2 are fixedly connected between the bases 1 through primary and secondary screws 4.

During assembly, the female screws 42 in the male and female screws 4 are inserted into the assembly holes 10 of the base 1 and are fully inserted into one side. The bearing 3 is pressed into the inner hole of the straightening wheel 2 from two sides, the female nail 42 pre-installed on the base 1 is pressed into the inner ring of the bearing 3, and then the adjacent base 1 is pre-locked by the male and female nails 44 in the male and female screws 4. And finally, penetrating a steel pipe with a corresponding diameter for self-centering, and cross locking the primary and secondary screws 4 after self-centering.

After the assembly is finished, the coil pipe penetrates through one end of the straightener, an inward concave arc surface 22 is arranged on the outer circumferential surface of the straightening wheel 2, the arc surface 22 is attached to the outer surface of the coil pipe, and the coil pipe is pulled out from the other end of the straightener to finish the straightening work. The utility model discloses an among the preferred scheme, straightener wheel 2 is preferred four groups, and every group has four at least, and the coil pipe can follow four directions and evenly straighten, and straightens the stroke length, has avoided the not thorough phenomenon of straightening.

The straightening wheels 2 can be made of different materials according to the material and hardness of the straightening coil. The utility model discloses an aspect lies in, straightening wheel 2 can carry out corresponding change according to straightening coil's size of a dimension, during the change, only need loosen the son nail 44 in the primary and secondary screw 4 can, it is convenient to change, and application scope is wide.

The invention has been described with reference to the preferred embodiments, to the above examples which are not intended to limit the invention, and from reading the present description, those skilled in the art will be able to conceive of numerous modifications and variations to this structure, without departing from the inventive concept, any obvious alternative falling within the scope of the invention.
