In the present invention, the rolling wheel 10 and the pressing wheel 40 do not actively rotate, the ring is rotated by the working platform 20, and the rolling wheel 10 and the pressing wheel 40 are moved relatively by the rotation of the ring under the action of friction.
Referring to fig. 2-3, the rolling wheel 10 and the pressing wheel 40 are oppositely arranged, the rolling wheel 10 is in a shape with a wide middle and two narrow ends, the wider side of the rolling wheel 10 is an inner end surface 11, the narrower side is the inner end surface 11, and the rolling wheel 10 and the inner end surfaces are circular and are coaxially arranged. A circumferential portion 13 is provided between the inner end surface 11 and the outer end surface 12, so that the roller 10 as a whole has a conical structure. In the use process, the side surface of the circumferential part 13 of the rolling wheel 10 is always attached to the ring piece, namely, the bottom of the side surface of the circumferential part 13 is parallel to the upper surface of the edge of the ring piece, so that the consistency of the surface shape of the ring piece after rolling can be effectively ensured. As can be seen in fig. 3, a through supporting hole 14 is formed in the middle of the rolling wheel 10 and is used for movably connecting with the bracket 30, so that the rolling wheel 10 can rotate around the shaft.
The pinch roller 40 is designed to have the same width at both ends and to be cylindrical, and the side surface of the pinch roller is also attached to the upper surface of the edge of the ring.
In the present invention, the rolling wheel 10 and the pressing wheel 40 are designed to be oppositely arranged. When the rolling wheel 10 rolls, the shape of one side of the ring piece is changed, which easily causes the edge warping phenomenon of the other side, and at the moment, the pressure wheel of the invention can press the warped side, thereby effectively solving the problem of edge warping.
