Machined Aluminum Wheel Forging , Kingrail OEM 6061 T6 Cast Aluminum Rims

monoblock precision-machined forged 6061-T6 aluminum centers and rim for luxury vehicle applications

The invention relates to a production process of high-strength and high-toughness forged aluminum alloy wheels, which relates to the technical field of aluminum alloy wheels. The process is roughly aluminum alloy bar selection, aluminum alloy bar preparation, aluminum alloy bar heating, pre-forging process, forming forging process, flaring forging process, spinning and drawing process, heat treatment process, lathe roughing, machining center Drilling process. Compared with the prior art, by improving the aluminum alloy production process, the present invention controls the process conditions more reasonably according to the wheel structure and stress characteristics, and the grain structure is refined and arranged in an orderly manner during the forging process of the aluminum alloy bar. The original internal structure of the aluminum alloy is obtained. The hardness of the wheel manufactured by this process can reach 120-130HB, the tensile strength is 400-450MPa, and the elongation after breaking is 12-14%. Compared with the traditional wheel, the weight is reduced by 17-22Kg.

The raw material is T6-6061(or 6082,or 6110), main production process is Forging--Spinning---Heat treatment---CNC----Powder coat
A final press forging process for an axle box body of a rail vehicle bogie, comprising: heating a pre-press forging box blank to 420°C-440° C, and maintaining the temperature for a duration of more than or equal to 210 minutes, and heating a pre-press forging die to 350°C-450°C, the heating time is greater than or equal to 8 hours; the cuboid-shaped ingot is pre-forged through the pre-press forging die, and the pre-forging temperature is 420° C-440° C, and the final forging is performed. The temperature is greater than or equal to 380 ℃ to form the axle box. The rail vehicle bogie axle box body final pressure forging process provided by the invention, the aluminum alloy obtained by the method, the bogie axle box body produced by the aluminum alloy has high tensile strength, yield strength and elongation rate, which can meet the requirements of high-speed railway bogies Mechanical performance requirements of the axle box.

For the forging and heat treatment process of free forgings, weigh the following raw materials by weight: Cr: 0.5%-1.0%, Mg: 5.0%-7.5%, Zn: 0.05%-0.10%, Ti: 0.03%-0.05%, Cu: 1.5 %? 2.0%, Fe: 0.10%? 0.15%, slag cleaning agent: 3.5%? 5.0%, and the balance is Al; the slag cleaning agent can remove the hydrogen and floating oxidation slag inclusions in the aluminum alloy liquid, and make the alloy liquid more Pure, its own strong adsorption properties can adsorb slag inclusions and improve the purity of aluminum alloys, and the chemical structure of the added sodium hexafluoroaluminate is similar to that of alumina. The surface tension when it is in contact with the aluminum melt, and then the aluminum oxide in the aluminum alloy liquid is removed; the addition of sodium fluoride can erode the metal on the interface between the aluminum oxide and the aluminum, so that the oxide film falls off and falls into the flux. Aluminum alloy for purification.
