Problems solved by technology
[0003] For cast wheels in the current market, it has the advantages of high productivity, mature technology and low investment requirements, but casting defects such as air holes, shrinkage cavities, shrinkage porosity and slag inclusions are prone to occur during the production process of cast wheels
Therefore, it is necessary to increase the size of the hub structure to ensure the safety of the rim during use, and the machining allowance is large
For forged rims, it has very good comprehensive mechanical properties, and its quality is much lighter than that of cast rims. However, forged rims have higher requirements for equipment and more complicated processes. Therefore, their production costs are lower than those of cast rims. rims are much higher

The invention discloses an integral light alloy rim isothermal forging die, and heating rods can be inserted into the integral light alloy rim isothermal forging die. The integral light alloy rim isothermal forging die includes an upper template, an upper die body arranged on the upper template, a lower template, a lower die body arranged on the lower template, a plurality of bolts, and a plurality of springs; the upper die body includes an upper die core and a pre-tension casing, the pre-tension casing is arranged on the upper template through the bolts and the springs, the upper die core is arranged between the upper template and the pre-tension casing; the upper die core is provided with installation holes into which the heating rods can be inserted. The die is provided with the installation holes into which the heating rods can be inserted, the temperature of the blank and the temperature of the upper die body and the lower die body is identical during the whole forging process, the plasticity of the blank is fully played, and the service life of the forging die is prolonged.
Description
【Technical field】 [0001] The invention relates to an isothermal forging die for an integral light alloy wheel rim, in particular to an isothermal forging die for forging an integral light alloy wheel rim in the field of automobile manufacturing. 【Background technique】 [0002] Due to people's increasingly strict requirements on the safety, environmental protection, emission and noise emission of automobiles. Therefore, the lightweight requirements for automotive structural parts are getting higher and higher, and the main focus of automotive lightweight lies in the vehicle's walking system. If the comprehensive mechanical properties of the automobile wheel rim can be improved and the quality of the wheel hub can be reduced, it will have an important impact on improving the energy saving and environmental protection of the automobile. At present, the manufacturing technology of rims at home and abroad mainly contains two types: one is casting forming, and the other is forgin...
