The upper end face of the upper ring 302 has three sets of stepped annular surfaces arranged sequentially from the outside to the inside along the central axis: a mounting surface 3021, a wear-resistant surface 3022, and a dust-receiving surface 3023. The mounting surface 3021 is the top end face of the upper ring 302. The wear-resistant surface 3022 is positioned lower than the mounting surface 3021, and the dust-receiving surface 3023 is positioned lower than the wear-resistant surface 3022. Figure 5 As shown, a lower annular wear-resistant plate 304 is provided on the wear-resistant annular surface 3022, and an annular dust-receiving groove 305 is provided on the dust-receiving annular surface 3023.

The reset cylinder 1301 is fixedly mounted on the mounting end cover 1302, and the mounting end cover 1302 is fixedly mounted on the outer circular surface of the middle plate body 401.

[0047] like Figure 8 As shown, the upper plate assembly 5 includes an upper plate body 501, which is a ring-shaped structural component. Several pad mounting grooves 5011 are evenly distributed circumferentially on the top end face of the upper plate body 501.

[0050] like Figure 4 As shown, the expanding claw assembly 7 includes an expanding claw body 701. The expanding claw body 701 is a unit piece that is a cylinder radially cut into several parts along its central axis. The cylinder has a conical hole along its central axis. Therefore, the inner surface of the expanding claw body 701 is a conical inclined surface 7011, which is matched with the pyramidal surface 602. The outer edge of the expanding claw body 701 is a cylindrical surface 7012. A limiting sliding block 702 is provided below the expanding claw body 701.

An upper wear-resistant liner 703 is provided on the upper end surface of the limiting sliding block 702, and a lower wear-resistant liner 704 is provided on the lower end surface of the limiting sliding block 702. A guide rail 705 is suspended above the limiting sliding block 702, and one end of the guide rail 705 is fixedly connected to the outer cylindrical surface of the expanding claw body 701.

[0051] like Figure 1 , Figure 2 , Figure 5 As shown, the bulging claw body 701 is correspondingly arranged with the pyramidal surface 602 of the pyramidal body 6. The limiting sliding block 702 is arranged facing the inner ring wall of the middle plate body 401 and is arranged between the upper plate body 501 and the upper ring 302. The upper plate annular wear-resistant plate 503 and the upper wear-resistant liner 703 are matched and arranged. The lower plate annular wear-resistant plate 304 and the lower wear-resistant liner 704 are matched and arranged. The guide rail 705 is arranged on the guide rail pad 502. The reset assembly 13 is matched with the limiting sliding block 702. When the piston rod of the reset cylinder 1301 is output, the piston rod end pushes the limiting sliding block 702 to move towards the pyramidal body 6. The guide rail 705 slides on the guide rail pad 502 and the bulging claw body 701 resets towards the pyramidal surface 602.

[0052] In this embodiment, the outer edge of the pyramid body 6 is evenly divided into twelve equal parts, that is, 12 sets of pyramidal surfaces 602 are provided. Each set of pyramidal surfaces 602 is provided with a set of bulging claw components 7.

[0053] This embodiment includes 12 sets of expanding claw assemblies 7. Twelve sets of guide rail pads 502 are provided to match the expanding claw assemblies 7, i.e., twelve sets of pad mounting grooves 5011 are provided; twelve sets of reset components 13 are also provided to match the expanding claw assemblies 7. In actual production, the pyramidal surface 602 of the pyramidal body 6 can be provided with different numbers of sets, and corresponding expanding claw assemblies 7, pad mounting grooves 5011, and reset components 13 can be provided accordingly.

[0054] like Figure 9 As shown, several roller mounting grooves 5012 are evenly distributed around the top end face of the upper plate body 501. The roller mounting grooves 5012 are arranged radially along the upper plate body 501. A rotating roller assembly 12 is arranged inside the roller mounting groove 5012. The rotating roller assembly 12 is used to support and rotate the annular forging 11 sleeved on the bulging claw assembly 7.

[0055] like Figure 8 , Figure 9 As shown, the rotating roller assembly 12 includes a rotating roller 1201, a rotating motor 1202, a rotating encoder 1203, a support roller 1204, and a roller cover plate 1205. The rotating roller 1201 is disposed in the roller mounting groove 5012. The rotating motor 1202 is disposed at one end of the shaft of the rotating roller 1201. The rotating motor 1202 is fixedly disposed on the outer ring wall of the upper plate body 501. The rotating encoder 1203 is disposed on the rotating motor 1202, and the rotating encoder 1203 controls the angular displacement of the annular forging. To achieve multi-angle forming operations on the ring forging, a knurled groove 12011 is provided on the outer circular surface of the rotating roller 1201. A support roller 1204 is provided below the rotating roller 1201 to support the rotating roller 1201. The support roller 1204 is provided with a smooth cylindrical surface 12012 at the position of the rotating roller 1201 corresponding to the support position of the support roller 1204. A roller cover plate 1205 is provided above the rotating roller 1201 to prevent the rotating roller 1201 from jumping horizontally upward.

[0056] In this embodiment, the rotating roller assembly 12 is provided with three sets.

[0057] like Figure 1 , Figure 10 As shown, the lower plate assembly 3 is provided with an anti-rotation guide rod assembly 9. The anti-rotation guide rod assembly 9 includes a support guide post 901, which is disposed between the lower ring 301 and the upper ring 302. A sliding guide sleeve 902 is slidably sleeved on the support guide post 901. A connecting rod 903 is fixedly disposed at the piston rod end of the lifting cylinder 2. The other end of the connecting rod 903 is fixedly disposed on the sliding guide sleeve 902 to prevent the piston rod of the lifting cylinder 2 from rotating relative to the cylinder.

[0058] like Figure 10As shown, a sensing column 904 is provided on the outer wall of the sliding guide sleeve 902, and the sensing column 904 is vertically downward. A displacement sensor 10 is provided on the outer side of the top flange of the lifting cylinder 2. The sensing column 904 is matched with the displacement sensor 10. Through the controllable hydraulic cylinder stroke by the displacement sensor, when the piston rod of the lifting cylinder 2 is lifted upward, the displacement sensor 10 can detect the rising distance of the sensing column 904, thereby detecting the upward lifting distance of the pyramid body 6, and thus knowing the outward expansion dimension of the expansion claw assembly 7. The upward lifting distance of the lifting cylinder 2 can be set according to the forming amount of the ring forging.

[0059] like Figure 11 , Figure 12 As shown, to accommodate the forming of ring forgings of different diameters, each set of expanding claw assemblies 7 is equipped with a set of mold assemblies 8. The mold assembly 8 includes a ring segment 801, a first connecting piece 802, and a second connecting piece 803. The ring segment 801 is a unit arc segment of a ring of different diameters that is evenly divided circumferentially. The ring segments 801 of different diameters are arranged radially on the guide rail 705 in order of increasing diameter. The ring segment 801 of the smallest diameter is set on the cylindrical surface 7012 of the expanding claw body 701. The first connecting piece 802 is set at the top of the ring segment 801 of the smallest diameter. The first connecting piece 802 is fixedly set on the expanding claw body 701. The other ring segments 801 are fixedly connected by the second connecting piece 803.

[0060] In this embodiment, the annular segment 801 is a unit arc segment divided into twelve equal parts. For example... Figure 11 As shown, twelve sets of molds are arranged circumferentially on the forming claw assembly 7 to form forming rings of different diameters to adapt to ring forgings of different diameters, thus enhancing the adaptability of this device.

[0061] When the forming process begins, the initial state of the machine is that the piston rod of the lifting cylinder 2 is in the retracted state, the pyramid body 6 is in its original lowered position, the expanding claw body 701 is in contact with the pyramid body 6, and the expanding claw assembly 7 is in the retracted state. The lifting height of the lifting cylinder 2 is set according to the size and specifications of the annular forging to be shaped. The deformed annular forging 11 is fitted onto the closed outer cylindrical surface of the expanding claw body 701. The piston rod of the lifting cylinder 2 is lifted, the pyramid body 6 is lifted upward, and the expanding claw body 701 expands outward to shape the annular forging 11 fitted on it. After one shaping is completed, the piston rod of the lifting cylinder 2 is retracted, the pyramid body 6 is lowered, and the piston rod of the reset cylinder 1301 is extended. The piston rod pushes the expanding claw body 701 towards the pyramid body 6 to retract and reset. The rotary motor 1202 starts, and the rotary roller 1201 begins to rotate. After the annular forging 11 on the rotary roller 1201 rotates a certain circumferential displacement, the rotary motor 1202 stops, the rotary roller 1201 stops rotating, and the annular forging 11 stops, undergoing another shaping process. The piston rod of the lifting cylinder 2 lifts, the pyramid body 6 rises upward, and the expanding claw body 701 expands outward to shape the annular forging 11 fitted on it. After the annular forging 11 rotates a certain circumferential displacement again, the shaping process continues. When the dimensions of the annular forging 11 reach the standard, it is removed from the expanding claw body 701. New annular forgings 11 that need shaping can be fitted onto the expanding claw body 701 for further shaping.

[0062] When the size of the annular forging 11 that needs to be shaped increases, a set of mold assembly 8 is set on each set of bulging claw assembly 7, and an appropriate number of annular segments 801 are set to correspond to the annular forging 11 of different specifications. The annular forging 11 is then fitted onto the cylinder composed of annular segments 801 for shaping.

[0063] This device has a compact structure and is easy to operate. It can adapt to the shaping of ring forgings 11 of different specifications and sizes, effectively and accurately shaping the roundness of the ring forgings, reducing material consumption and manufacturing costs.
