Description

Technical Field

[0001] This utility model relates to the field of forging die frame technology, and in particular to a die frame for forging automotive wheel hubs. Background Technology

[0002] Automotive wheel hubs are one of the key automotive components, and their strength and quality directly affect the performance and safety of the vehicle. Forging molds and die sets for automotive wheel hubs are mainly used in the automotive manufacturing industry. Especially in the production of automotive wheel hubs, the molds and die sets are a key component in the forging process, undertaking the forming, heating, cooling and other process steps of the forging, ensuring that the final product has the required dimensional accuracy, strength and appearance.

[0003] A forging die set for automotive wheel hubs includes an upper forming die, a sliding track, and a cooling frame. The die forces a heated metal blank to a specific temperature under high pressure, ensuring uniform metal flow within the die and maintaining the wheel hub's shape during cooling. This results in a wheel hub that meets design requirements. The die set not only provides the necessary pressure for forming but also guarantees the product's precision and quality. During the forging process, the die set design, material selection, temperature control, and pressure control directly impact the final product's quality and production efficiency.

[0004] In the existing technology, after the wheel hub forming operation is performed, some mold bases can only pause the process during the cooling process, remaining in the mold to wait for the cooling to complete. The length of the cooling time directly affects the production efficiency and the overall production cycle. This operation method not only consumes a lot of time, but also causes idle production lines and waste of resources, failing to effectively improve production efficiency. Therefore, a wheel hub forging processing mold base for automobiles is proposed to solve the above problems. Utility Model Content
