What are the processes for forging wheel forgings?

Tire die forging is a forging method in which the blank is directly used for forging or the blank is pre-forged into the shape and size required for tire forging through free forging, and then the tire mold is used for final forging forming on the free forging equipment.

       In addition to upper and lower flat anvils and general forging tools, tire die forging also requires a dedicated tire mold. The tire mold is not fixed on the forging equipment, it is placed on the lower flat anvil of the equipment when used, and removed when not in use. It is convenient to use, does not require installation, greatly saves the time of trial mold, and the process operation is flexible and diverse; due to metal deformation It is always completed in the die. The shape and size of the wheel forgings are mainly guaranteed by the tire mold, so wheel forgings with complex shapes and accurate dimensions can be obtained, and the number of heating and deformation processes required are also reduced, thus not only improving the metal material Utilization rate, and reduce mechanical processing man-hours, greatly improve labor productivity.

 In terms of the quality of wheel forgings, due to the role of the mold during the forming process, the metal deformation is limited. The forged wheel forgings are densely structured, the quality of the wheel forgings is relatively good, the surface quality is also good, and the machining allowance is also small. , The utilization rate of materials is greatly improved, the production efficiency is relatively high, and it can forge wheel forgings with more complex shapes; and it can also produce large wheel forgings on small equipment, and it can also be partially formed. Based on the above advantages, tire mold forging It has been valued and favored by many manufacturers.

       In the free forging production of wheel forgings, upsetting is a very important deformation process. The reasonable choice of upsetting process parameters plays a decisive role in the quality of wheel forgings. Repeated upsetting can not only increase the forging ratio of the blank, but also crush the carbides in the alloy steel to achieve uniform distribution; it can also improve the lateral mechanical properties of the wheel forgings and reduce the anisotropy of the mechanical properties.
