However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0026] Please see Figures 1-5 This utility model provides a technical solution: a seat ring press material box, including a seat ring press material box body, the seat ring press material box body includes a powder discharge pipe 1, a top plate 2 and ear plates 3 connected to both sides of the top plate 2, a partition plate 4 is connected between the two ear plates 3 at the bottom of the top plate 2, the partition plate 4 divides the seat ring press material box body into left and right cavities, and the top plate 2 on both sides of the partition plate 4 is provided with through holes 21, the powder discharge pipe 1 is installed in the two through holes 21 with a 45-degree inclined structure, and a butterfly valve switch 11 is provided in the middle of each powder discharge pipe 1, the powder discharge pipe 1 is connected to the top plate 2 by bolts, the powder discharge pipe 1 is made of stainless steel, the bottom of the powder discharge pipe 1 is on the same horizontal plane as the top of the top plate 2, and the top plate 2, ear plates 3 and partition plate 4 are integrally machined from aluminum alloy.

[0027] It should be noted that in this embodiment, the mounting through hole 21 is designed with an opening angle of 45° to ensure that the powder pipe 1 is installed in a 45-degree inclined structure inside the two mounting through holes 21, so as to facilitate the rapid flow of powder, improve component segregation, and enable the powder to flow more smoothly into the mold cavity, thereby improving production efficiency.

[0028] Furthermore, the top plate 2, ear plate 3, and partition plate 4 are CNC machined from 7075 aluminum alloy, ensuring the high strength and wear resistance of the material box. This material selection not only improves the stability of the overall structure but also reduces the risk of deformation during production. The integrated machining of 7075 aluminum alloy significantly improves the production efficiency of the seat ring press material box. The integrated design reduces assembly steps and time, making the production process smoother and more efficient, which helps to improve the overall production speed. 7075 aluminum alloy has excellent mechanical properties and can withstand high pressure and impact. 7075 aluminum alloy has good thermal conductivity, and the integrated machining can effectively improve the heat dissipation performance of the seat ring press material box. Good heat dissipation performance can prevent the equipment from overheating, extend its service life, and ensure a continuous and stable working state.

[0029] Furthermore, the powder feeding pipe 1 is made entirely of 304 stainless steel. 304 stainless steel has good corrosion resistance and wear resistance, which helps to maintain the purity and stability of the powder. It is fixed to the material box with bolts. At the same time, a self-designed butterfly valve switch is used in the middle of the powder pipe. The entire material box device is in a fully sealed state, which can effectively prevent the powder from getting damp and clumping.

[0030] Please see Figure 2 and 5 The bottom of the material box body of the seat ring press is provided with a wear-resistant plate 5. The wear-resistant plate 5 is rectangular and is installed at the bottom of the material box body of the seat ring press by bolts. A horizontal plate 51 corresponding to the position of the partition plate 4 is integrally connected in the middle of the wear-resistant plate 5. As a preferred embodiment of this utility model, the wear-resistant plate 5 and the integrally connected horizontal plate 51 are made of tin-phosphor bronze.

[0031] It should be noted that in this embodiment, the wear-resistant plate 5 and the integrally connected horizontal plate 51 are CNC machined using ZCuSn10P1 tin-phosphorus bronze. ZCuSn10P1 tin-phosphorus bronze is a cast copper alloy with high strength, high wear resistance, and good corrosion resistance. ZCuSn10P1 tin-phosphorus bronze is mainly composed of copper (Cu) balance, tin (Sn) 9.0-11.5%, and phosphorus (P) 0.5-1.0%. In addition, it also contains trace amounts of impurities such as zinc (Zn), lead (Pb), nickel (Ni), aluminum (Al), iron (Fe), manganese (Mn), silicon (Si), antimony (Sb), and sulfur (S), with a total amount not exceeding 0.75%. The alloy has a hardness of 885HB, tensile strength σb ≥360MPa, yield strength σ (reference value) ≥170MPa, and elongation δ5 ≥6%. It exhibits good thermal stability, wear resistance, and corrosion resistance within an operating temperature range of ~280℃, effectively extending the service life of equipment and improving production efficiency and product quality.

[0032] The working process of this utility model

[0033] During use, the powder supply pipe 1 is installed at a 45-degree angle inside the mounting through hole 21 on the top plate 2. Ensure that the butterfly valve switch 11 in the middle of each powder supply pipe 1 can work normally, and that the bottom of the powder supply pipe 1 is on the same horizontal plane as the top of the top plate 2. The wear-resistant plate 5 is installed at the bottom of the seat ring press material box body by bolts, and ensure that the horizontal plate 51 connected in the middle of the wear-resistant plate corresponds to the position of the partition plate 4. Ensure that the entire seat ring press material box device is in a fully sealed state to prevent the powder from getting damp and clumping. Check whether all connection points are tight and whether the butterfly valve switch 11 is working normally. Before formal use, conduct a no-load test run to observe the powder flow and ensure that there is no leakage or blockage. Before pressing the final metallurgical valve seat ring product, the mixed powder enters the powder supply pipe 1. The butterfly valve switch 11 inside the powder supply pipe 1 is opened as needed. After opening, the powder enters the interior of the seat ring press material box body cavity. After the press moves to the fixed position of the filling state, the powder flows into the mold cavity for pressing and forming.
