DETAILED DESCRIPTION
[0025] The present application will be further described below in conjunction with the drawings.
[0026] As Figures 1-4 shown, a truck traction bearing base extrusion forging die with reinforcing rib structure, comprising traction bearing base forging upper die 1 and traction bearing base forging lower die 2, the traction bearing base forging upper die 1 is provided with die closing convex part 3 and extrusion convex part 4 in it, the traction bearing base forging lower die 2 is provided with die closing concave part 5 and extrusion concave cavity 6 in it, the position of the die closing convex part 3 corresponds to that of the die closing concave part 5 and their shapes are matched, the position of the extrusion convex part 4 corresponds to that of the extrusion concave cavity 6 and their shapes are matched, the extrusion concave cavity 6 is provided with reinforcing rib synchronous forming structure 7 in it, and the reinforcing rib synchronous forming structure 7 is arranged opposite to the extrusion convex part 4.
[0027] In this embodiment, during the mold closing process, the mold closing protrusion 3 is embedded into the mold closing recess 5 to achieve precise alignment of the upper and lower dies, ensuring the stability of the billet position during forging. The extrusion protrusion 4 corresponds to the extrusion cavity 6 in position and is matched in shape. During forging, the extrusion protrusion 4 applies pressure to the billet in the extrusion cavity 6, causing the billet to be formed within the extrusion cavity 6. The extrusion cavity 6 is provided with a reinforcing rib synchronous forming structure 7, which is directly opposite the extrusion protrusion 4. Thus, when the extrusion protrusion 4 extrudes the billet, the reinforcing rib synchronous forming structure 7 can simultaneously form a reinforcing rib structure on the billet. Through the precise cooperation between the mold closing protrusion 3 and the mold closing recess 5, and between the extrusion protrusion 4 and the extrusion cavity 6, stable positioning of the billet and efficient forging are achieved. At the same time, the direct alignment of the reinforcing rib synchronous forming structure 7 with the extrusion protrusion 4 ensures that the reinforcing rib can be formed synchronously during forging, improving production efficiency and product quality.
[0028] Combination Figures 1-4 As shown, the extrusion cavity 6 is provided with an auxiliary forming block 8, and the reinforcing rib synchronous forming structure 7 is located at the auxiliary forming block 8.
[0029] Specifically, the auxiliary forming block 8 can better assist the blank in forming at specific locations. Working in synergy with the reinforcing rib synchronous forming structure 7, it makes the forming of the reinforcing rib more precise. The setting of the auxiliary forming block 8 optimizes the structure of the reinforcing rib forming area, which helps to improve the accuracy and quality of reinforcing rib forming.
[0030] The reinforcing rib synchronous forming structure 7 includes a reinforcing rib forming groove 9 disposed in the auxiliary forming block 8, and the reinforcing rib forming groove 9 is connected to the extrusion cavity 6.
[0031] In this embodiment, when the extrusion protrusion 4 extrudes the blank, a portion of the blank flows into the reinforcing rib forming groove 9, thereby forming the reinforcing rib. The simple yet ingenious design of the reinforcing rib forming groove 9 makes the reinforcing rib forming process intuitive and efficient, and can precisely control the shape and size of the reinforcing rib.
[0032] Combination Figure 3 , Figure 4 As shown, the auxiliary molding block 8 also has an alignment protrusion molding cavity 10. One side of the reinforcing rib molding groove 9 is connected to the protrusion molding cavity 10, and the other side is connected to the extrusion cavity 6.
[0033] In this embodiment, the alignment protrusion forming cavity 10 is used to form a specific alignment protrusion structure. It works in conjunction with the reinforcing rib forming groove 9, increasing the diversity and functionality of the product structure. The interconnected design of the alignment protrusion forming cavity 10 and the reinforcing rib forming groove 9 allows the alignment protrusion to be formed at the same time as the reinforcing rib, meeting more needs of the product in assembly and other aspects.
[0034] The extrusion protrusion 4 comprises an extrusion protrusion 11 arranged in the traction bearing base forging upper die 1, which corresponds to the position of the auxiliary forming block 8 and is matched in shape.
[0035] In this embodiment, during forging, the extrusion protrusion 11 extrudes the blank at the auxiliary forming block 8, so that the blank is formed at the structure in the auxiliary forming block 8. The precise matching of the extrusion protrusion 11 and the auxiliary forming block 8 ensures the accurate forming of the blank in the auxiliary forming block 8 area, thereby improving the product quality.
[0036] In combination with Figure 3 As shown, the extrusion protrusion 11 is provided with a hole and groove forming protrusion 12, which is arranged opposite to the alignment protrusion forming cavity 10.
[0037] In this embodiment, during extrusion, the hole and groove forming protrusion 12 can form a hole and groove structure at the corresponding position of the blank, which cooperates with the alignment protrusion forming cavity 10 to realize the forming of a specific structure. The arrangement of the hole and groove forming protrusion 12 further enriches the formable structure of the product and improves the universality of the die and the functionality of the product.
[0038] The traction bearing base forging upper die 1 has an end sealing protrusion 13.
[0039] In this embodiment, the end sealing protrusion 13 plays a sealing role when the mold is closed, preventing the metal liquid from overflowing during forging. The arrangement of the end sealing protrusion 13 improves the sealing performance of the forging process, ensures the forging quality, and reduces the scrap rate.
[0040] In combination with Figures 1-4 As shown, the traction bearing base forging lower die 2 has an end sealing groove 14, and the end sealing protrusion 13 is arranged opposite to the end sealing groove 14. The end sealing protrusion 13 is connected to the extrusion protrusion 11, and the end sealing groove 14 is connected to the extrusion cavity 6.
[0041] In this embodiment, when the mold is closed, the end sealing protrusion 13 is embedded in the end sealing groove 14 to form a good sealing structure. The cooperation of the end sealing protrusion 13 and the end sealing groove 14 further enhances the sealing effect, ensuring the stability of the forging process and the product quality.
[0042] In combination with Figures 1-4 As shown, the mold closing protrusion 3 comprises a mold closing protrusion 15 arranged in the traction bearing base forging upper die 1 and two mold closing alignment protrusions 16.
[0043] In this embodiment, the mold convex strip 15 and the two mold alignment protrusions 16 are matched with the corresponding structures of the lower mold during the mold closing, so that the mold is closed accurately.
[0044] In combination Figures 1-4 As shown in the figure, the mold recess 5 includes a mold side groove 17 and a mold alignment recess 18 arranged in the traction bearing base forging lower mold 2, the mold convex strip 15 is arranged opposite to the mold side groove 17, and the mold alignment protrusion 16 is arranged opposite to the mold alignment recess 18.
[0045] In this embodiment, during the mold closing, the mold convex strip 15 is embedded in the mold side groove 17, and the mold alignment protrusion 16 is embedded in the mold alignment recess 18, so that the upper and lower molds are accurately aligned, and the accurate matching of the mold convex strip 15 and the mold side groove 17 and the mold alignment protrusion 16 and the mold alignment recess 18 ensures the accuracy of the mold closing of the upper and lower molds, thereby providing a guarantee for forging high-quality products.
