[0041] In order to accurately position and install the upper gasket 12 at the bottom of the upper die plate 11, an upper positioning disc 16 is fixedly arranged at the bottom of the upper die plate 11, and a corresponding upper positioning hole 121 is formed in the center of the upper gasket 12. The shape and size of the upper positioning hole 121 are the same as those of the upper positioning disc 16. When the upper gasket 12 is installed, the upper positioning disc 16 is inserted into the upper positioning hole 121, and then the upper gasket 12 is fixed to the upper die plate 11 by bolting, so that the upper gasket 12 is accurately and fixedly installed on the upper die plate 11.

[0042] The lower die 2 includes a lower die plate 21, a lower gasket 22, a plurality of breaking punch 23 and a lower tightening block 24, wherein the lower gasket 22 is fixedly arranged at the center of the lower die plate 21. In order to accurately position and install the lower gasket 22 on the lower die plate 21, a lower positioning disc 25 is fixedly arranged at the surface center of the lower die plate 21. A corresponding lower positioning hole 221 is formed through the surface center of the lower gasket 22, and the lower positioning disc 25 is inserted into the lower positioning hole 221 when the lower gasket 22 is installed, so that the lower gasket 22 is accurately and fixedly installed on the lower die plate 21.

[0043] Referring to Figure 3 , Figure 4 and Figure 6The lower tightening block 24 is annular, and is composed of a lower tightening portion 241 and a fixing portion 242, the fixing portion 242 protruding from the inner side wall of the lower tightening portion 241. The lower tightening block 24 is installed on the lower cushion block 22, so that the fixing portion 242 is below the lower tightening portion 241 and abuts against the lower cushion block 22. In order to make the lower tightening block 24 firmly installed on the lower cushion block 22, a pressing plate 26 is arranged above the lower cushion block 22, the pressing plate 26 is arranged in the lower tightening block 24 and is in close contact with the inner side wall of the lower tightening block 24, and the peripheral bottom end of the pressing plate 26 is arranged on the fixing portion 242 of the lower tightening block 24, so that the pressing plate 26 plays a fixing role on the lower tightening block 24. A plurality of breaking convex molds 23 are vertically arranged on the pressing plate 26, and the plurality of breaking convex molds 23 are arranged along the inner side wall of the lower tightening block 24.

[0044] The rim to be processed is installed on the lower die 2, so that the rim is sleeved on the periphery of the lower tightening block 24 and the lower cushion block 22. In order to make the rim keep stable on the lower die 2, a plurality of gaskets 4 are fixedly arranged on the lower die plate 21, the plurality of gaskets 4 are uniformly distributed along the outer side of the lower cushion block 22, and the rim is installed on the lower die 2, so that the rim abuts against the gaskets 4. The gaskets 4 are made of rubber material, so that when the upper die 1 descends to process the rim, the gaskets 4 have a buffering effect on the rim, and the gaskets 4 can avoid causing damage to the rim during the tightening process.

[0045] After the rim is installed on the lower die 2, in order to make the rim and the lower tightening block 24 have good concentricity, a lower positioning ring 27 is sleeved on the periphery of the lower cushion block 22, the lower positioning ring 27 is annular, and a plurality of lower rectangular springs 28 are arranged between the lower positioning ring 27 and the lower die plate 21, and the two ends of the lower rectangular spring 28 are fixedly connected with the lower die plate 21 and the lower positioning ring 27 respectively. The outer side upper end of the lower positioning ring 27 is arranged as an inclined surface, and the lower positioning ring 27 is clamped between the rim and the lower tightening block 24 under the action of the lower rectangular spring 28, so that the inner side wall of the rim is in close contact with the inclined surface of the outer side top end of the lower positioning ring 27, and the rim and the lower tightening block 24 have good concentricity. The plurality of lower rectangular springs 28 make the lower positioning ring 27 and the lower die plate 21 have a certain runout space, so that the rim and the lower tightening block 24 still have good concentricity during the tightening process.

[0046] The upper die 1 is driven down by the ejection cylinder of the equipment. In order to make the rim and the upper parallel block 14 have good concentricity, the upper positioning ring 17 is arranged at the bottom end of the upper die 1. The upper positioning ring 17 is annular, is sleeved on the periphery of the upper backing plate 12, and a plurality of upper square springs 18 are arranged between the upper positioning ring 17 and the upper die plate 11. The two ends of the upper square spring 18 are fixed with the upper die plate 11 and the upper positioning ring 17 respectively. The upper positioning ring 17 is embedded between the rim and the upper backing plate 12 under the action of the upper square spring 18. At the same time, the inclined surface at the bottom end of the outer side of the upper positioning ring 17 abuts against the inner side wall of the rim, so that the rim and the upper parallel block 14 have good concentricity. The arrangement of the plurality of upper square springs 18 makes the upper positioning ring 17 and the upper die plate 11 have a certain run-out space, so that the rim can still have good concentricity with the upper parallel block 14 during the parallel process.

[0047] Referring to Figures 7-10 The upper die 1 and the lower die 2 are closed to make the rim parallel. At the same time, the center hole punch 13 is driven down to punch the center hole waste 9 at the flange 8. With the continuous downward movement of the center hole punch 13, the punched center hole waste 9 is broken into small pieces under the action of the breaking punch 23, so as to facilitate the removal of the center hole waste 9 from the rim. In order to facilitate the removal of the center hole waste 9 broken by the breaking punch 23 from the mold, the stripper plate 29 is arranged in the lower parallel block 24, and the stripper plate 29 is arranged above the pressing plate 26. A plurality of breaking grooves 291 are formed in the surface of the stripper plate 29. The number, shape and size of the breaking grooves 291 are matched with the breaking punch 23. After the stripper plate 29 is installed into the lower parallel block 24, the breaking punch 23 is arranged in the breaking groove 291. The outer side wall of the stripper plate 29 abuts against the inner side wall of the lower parallel block 24. In order to make the breaking punch 23 keep stable in the breaking groove 291, the limit part 231 is arranged at the bottom end of the breaking punch 23. A plurality of limit grooves 292 are formed in the outer bottom end of the stripper plate 29. The limit grooves 292 are communicated with the breaking grooves 291, and the limit part 231 of the breaking punch 23 is clamped in the limit groove 292. In addition, a plurality of spring grooves 261 are formed in the pressing plate 26 and the lower backing block 22, and the nitrogen gas spring 5 is arranged in each spring groove 261.

[0048] Referring to Figure 3 、 Figure 11 and Figure 12After the unloading plate 29 is installed into the lower and tightening block 24, the unloading plate 29 abuts against each nitrogen spring 5 and the pressing plate 26. After the center hole punch 13 descends, the center hole waste 9 is punched and broken by the breaking punch 23; at the same time, the center hole punch 13 descends to drive the unloading plate 29 to compress each nitrogen spring 5. After the center hole waste 9 is broken by the cooperation of the center hole punch 13 and the breaking punch 23, the upper die 1 is driven to ascend by the ejection cylinder of the equipment, and then the unloading plate 29 is lifted under the action of the nitrogen spring 5, so that the unloading plate 29 ejects the broken center hole waste 9. The nitrogen spring 5 and the lower cushion block 22 are locked and fixed by the fixing bolt 6, so that the nitrogen spring 5 remains stable in the spring groove 261 to avoid the nitrogen spring 5 from jumping during the lifting of the unloading plate 29. In addition, the setting of the unloading plate 29 also limits the descent of the center hole punch 13. Since the center of the rim flange 8 is thinned, the setting of the unloading plate 29 prevents the rim flange 8 from being crushed by the pressure of the main cylinder.

[0049] In order to accurately bend the center hole waste 9 after the center hole punch 13 descends, a positioning column 293 is fixedly arranged at the center of the unloading plate 29, and a guide hole 131 is formed through the center of the center hole punch 13, and the shape and size of the guide hole 131 are matched with those of the positioning column 293. When the center hole punch 13 descends, the positioning column 293 is arranged in the guide hole 131 of the center hole punch 13, so that the center hole punch 13 slides up and down along the outer wall of the positioning column 293, thereby accurately descending. In addition, a plurality of hanging arms 7 are fixedly arranged at the bottom end of the upper die plate 11 and the lower die plate 21. The main function of the hanging arm 7 is to provide a stable and flexible platform for installing and operating the mold. By adjusting the position and angle of the mold hanging arm 7, the operator can accurately control the contact point and force of the mold and the rim, thereby realizing high-precision processing. In addition, the hanging arm 7 can also reduce the labor intensity of the operator and improve the work efficiency.

[0050] Referring to Figures 13-16 When the rim needs to be tightened and the center hole is processed, the rim is sleeved on the periphery of the lower die 2, so that the bottom end of the rim abuts against the gasket 4, thereby keeping the rim horizontal, and the bottom end of the rim flange 8 abuts against the lower tightening block 24. The lower positioning ring 27 is lifted under the action of the lower spring 28, so that the top end of the lower positioning ring 27 is embedded between the rim and the lower tightening block 24, thereby keeping good concentricity between the rim and the lower tightening block 24.

[0051] Subsequently, the ejector rod, in conjunction with the ejector cylinder of the equipment, drives the upper mold 1 downwards, causing the upper clamping block 14 of the upper mold 1 to pass into the rim, and the bottom end of the upper clamping block 14 to abut against the upper end of the rim flange 8. At the same time, under the action of the upper torque spring 18, the bottom end of the upper positioning ring 17 is engaged between the rim and the upper clamping block 14, thereby maintaining good concentricity between the rim and the upper clamping block 14. As the ejector cylinder drives the upper mold 1 to continue downwards, the flange 8 of the rim is clamped together by the interaction of the upper clamping block 14 and the lower clamping block 24.

[0052] Simultaneously, the center punch 13 descends along the positioning post 293 to perform a punching and separation process on the rim's flange 8, breaking off the center hole waste 9 at the flange 8. The center hole waste 9 is annular in shape. As the center punch 13 continues to descend, the extrusion punches 23 break the center hole waste 9 into four small segments for easy removal. This continues until the bottom end of the center punch 13 abuts against the stripper plate 29. The stripper plate 29 serves to limit the descent of the center punch 13, preventing the rim flange 8 from being crushed by the main cylinder pressure. Subsequently, the ejector cylinder drives the upper die 1 to rise, and the stripper plate 29 rises under the action of the nitrogen spring 5, thus discharging the center hole waste 9.

[0053] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all protected by the present invention.
