Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a rack 1, a driving roller 2, a driven roller 3, a first mounting part 301, a rolling part 302, a second mounting part 303, a guide roller 4, a signal roller 5, a rolling wheel 6, an annular groove 7, a supporting plate 8, a square supporting rod 9, a square rod 10, a driving motor 11 and a speed reducer 12.

The embodiment is basically as shown in the attached figure 1: a stable form ring rolling machine comprises a rack 1, wherein a driving roller 2, a driven roller 3, a guide roller 4 and a signal roller 5 are respectively and rotatably connected to the outer wall of the rack 1. As shown in fig. 2, a driving motor 11 is disposed on the right side of the frame 1, an output end of the driving motor 11 is connected to a speed reducer 12, and an output end of the speed reducer 12 is coaxially and fixedly connected to the driving roll 2. And a telescopic device for controlling the radial movement of the driving roller 2 is also fixedly connected to the driving roller 2. The free end of the driving roll 2 is coaxially and fixedly connected with a rolling wheel 6, the outer wall of the rolling wheel 6 is provided with an annular groove 7, and the cross section of the annular groove 7 is of a rectangular structure. The driven roller 3 is positioned right below the driving roller 2, and the axis of the driven roller 3 and the axis of the driving roller 2 are positioned in the same vertical direction. As shown in fig. 3, the driven roller 3 includes a first mounting portion 301, a rolled portion 302, and a second mounting portion 303. The first mounting portion 301 is a small cylinder structure, the rolling portion 302 is a large cylinder structure, the second mounting portion 303 is a circular truncated cone structure, and the outer diameter of the second mounting portion 303 close to the rolling ring portion is larger than the outer diameter of the first mounting portion 301. And the first mounting part 301, the rolled part 302 and the second mounting part 303 are integrally formed.
