Then, the adjusting sleeve is nested from bottom to top onto the outside of the bushing assembly until the lower flange is assembled with the upper flange through a groove, connecting the second assembly hole with the first assembly hole. This completes the assembly of the bushing assembly and the adjusting sleeve. At this point, the bushing assembly is adapted to the installation specifications of the hydraulic platform cavity through the externally assembled adjusting sleeve, preventing installation gaps due to specification differences and ensuring installation firmness. Finally, bolts are used to pass through the first and second assembly holes to lock the bushing assembly into the cavity, thus completing the installation.

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1-2 This utility model provides an adjustable forming bushing structure for a powder hydraulic press, including an adjustable bushing structure 1. The adjustable bushing structure 1 includes a bushing assembly 11, a cavity 12, an upper flange 13, a first assembly hole 14, an adjusting sleeve 15, a lower flange 16, and a second assembly hole 17. The cavity 12 is vertically through the inside of the bushing assembly 11. The upper flange 13 is welded to the top of the outer side of the bushing assembly 11. The first assembly hole 14 is distributed along the edge of the upper flange 13. The adjusting sleeve 15 is movably nested and assembled on the outside of the bushing assembly 11. The lower flange 16 is welded to the top of the outer side of the adjusting sleeve 15. The second assembly hole 17 is distributed along the edge of the lower flange 16. The second assembly hole 17 has the same diameter as the first assembly hole 14 and their positions are corresponding.

[0020] Specifically, firstly, select an adjusting sleeve 15 with the appropriate outer diameter according to the hydraulic platform cavity. Then, nest the adjusting sleeve 15 from bottom to top onto the outside of the bushing assembly 11 until the lower flange 16 is assembled into a single unit with the upper flange 13 through the groove 18. This allows the assembly hole 2 17 to connect with the assembly hole 14, thus completing the assembly operation of the bushing assembly 11 and the adjusting sleeve 15. At this point, the bushing assembly 11 is adapted to the installation specifications of the hydraulic platform cavity through the externally assembled adjusting sleeve 15, preventing installation gaps due to specification differences and ensuring installation firmness. Finally, bolts are used to pass through the assembly hole 14 and the assembly hole 2 17 to lock the bushing assembly into the cavity, thus completing the installation. The bushing assembly 11 can be installed with cavities of different inner diameters through the adjusting sleeve 15, providing strong adjustability and reducing the pressure of component replacement.

[0021] To further explain, the adjusting sleeve 15 and the bushing assembly 11 are made of the same structural material to ensure structural strength.

[0022] This utility model provides an adjustable forming bushing structure for a powder hydraulic press. The top of the lower flange 16 is provided with a groove 18, which matches the size and specifications of the upper flange 13. The lower flange 16 is nested and installed on the outside of the upper flange 13 through the groove 18 to improve the installation and connection between the upper flange 13 and the lower flange 16.

[0023] Please see Figure 3-4 This utility model provides an adjustable forming bushing structure for a powder hydraulic press. At least eight slots 19 are evenly distributed on the inner wall of the adjusting sleeve 15. The slots 19 are vertically connected to the adjusting sleeve 15. A reinforcing rib 110 is vertically integrally provided on the outside of the bushing 11. The number of reinforcing ribs 110 is the same as that of the slots 19, and their distribution positions are corresponding. The slots 19 can be slidably fitted into the surface of the reinforcing ribs 110. Specifically, the structural cooperation between the slot 19 and the reinforcing rib 110 enhances the connection strength between the bushing 11 and the adjusting sleeve 15, and can lock the installation angle of the adjusting sleeve 15 to prevent it from rotating on its own.

[0024] When the slot 19 and the reinforcing rib 110 are in the fitted state, the positions of the first assembly hole 14 and the second assembly hole 17 are directly corresponding. The slot 19 and the reinforcing rib 110 can also play a positioning role to prevent the positions of the first assembly hole 14 and the second assembly hole 17 from deviating.
