[0022] The side of support J-shaped block 54 is penetrated and slidably connected with moving rod 59, one end of moving rod 59 is fixedly connected with L-shaped block 510, the top of L-shaped block 510 is provided with slot opening through pin 58 to fix support sliding block 55, through the setting of the above structure, the movement of support sliding block 55 will drive elastic roller 56 and pressure gauge 57 away from the working range of roller 11 and wheel hub blank, thereby avoiding the problem that elastic roller 56 and pressure gauge 57 are subjected to continuous heating and cooling cycle under high temperature of roller 11 and wheel hub blank, leading to the damage of elastic roller 56 and pressure gauge 57.

[0023] The side of the supporting slider 55 is provided with a protection device 6, which comprises a fixed arc plate 61 fixedly connected on the side of the supporting slider 55, a plurality of elastic expansion blocks 62 fixedly connected on the outer arc surface of the fixed arc plate 61, a pressing plate 63 fixedly connected on the expansion end of each of the elastic expansion blocks 62, and an arc-shaped storage tank 64 fixedly connected on the side, away from the elastic expansion blocks 62, of each of the pressing plates 63.

[0025] In use, the staff first fixes the supporting slider 55 with the rotating notch ring 52 through the pin 58, and then rotates the rotating notch ring 52 through the adjusting block 53. The rotation of the rotating notch ring 52 drives the supporting slider 55 to move along the inner wall of the supporting J-shaped block 54 through the pin 58. The movement of the supporting slider 55 drives the elastic roller 56 and the pressure gauge 57 to move. The elastic roller 56 is in close contact with the roller 11 through its own elastic force during movement. As the elastic roller 56 moves on the surface of the roller 11, the pressure gauge 57 detects the surface of the roller 11 through the supporting slider 55 and the elastic roller 56. When the surface of the roller 11 has cracks or peeling, the elastic roller 56 drives the supporting slider 55 to exert pressure on the detection end of the pressure gauge 57. By observing the value of the pressure gauge 57, it can be determined whether the surface of the roller 11 has cracks or peeling, thereby avoiding the cracks or peeling of the surface of the roller 11 causing irregular contact with the hub, resulting in uneven pressure distribution on the hub blank, thereby causing the size and shape of the hub to deviate.

The movement of the supporting frame 3 drives the roller 11 to approach the hub blank through the adjuster 8, the fixed frame 9, and the connecting block 10, thereby realizing the spinning forming of the hub blank. When the elastic roller 56 completes the detection of the roller 11, the staff rotates the supporting slider 55 to the L-shaped block 510, and then pulls out the pin 58 of the rotating notch ring 52, inserts the pin 58 into the slot of the L-shaped block 510, and fixes the supporting slider 55 and the L-shaped block 510 together. Then the staff pulls the moving rod 59, which drives the L-shaped block 510 to move. The movement of the L-shaped block 510 drives the supporting slider 55 to move through the pin 58. The movement of the supporting slider 55 drives the elastic roller 56 and the pressure gauge 57 to move away from the working range of the roller 11 and the hub blank, thereby avoiding the problem that the elastic roller 56 and the pressure gauge 57 are damaged due to continuous heating and cooling cycles under high temperature.
