Forged wheels manufacturing process

How to manufacture forged wheels ?

Forging is the use of high-voltage (mostly for thousands of tons of pressure) 6061 aluminum alloy has a heated pressure into the wheel blank (prototype) and CNC, detail carving two processing.

Due to the high pressure impact, the molecules between the alloys will be smaller, the gap will be thinner, the density will be higher, and the interaction force between the material molecules will be stronger, so the forged wheels will achieve enough rigidity and make the overall weight lighter. Because aluminum alloy is still in solid state during forging, forging can eliminate the defects such as casting porosity and so on during the smelting process, and optimize microstructure. At the same time, because of the complete metal flow line, the mechanical performance of forged wheels are generally better than that of casting wheels. The important parts with high load and severe working conditions are used for forging, except for simply shaped rolled plates, profiles or weldments.

The advantages of the forged wheels are light weight, high performance and high rigidity.

(1) cylindrical design, the bigger the diameter of the forged wheels is to use the rough aluminum alloy material to forge and press, and the casting wheel hub using the "raw material" manufacturing method is more different.

(2) cutting the aluminum according to the J number required for the width of the hub.

(3) the aluminum ingot is first heated to 400 centigrade, and then the forging can be prepared at this time.

(4) hot forging and forming. The working temperature of ingot forging machine tonnage higher required is low, product grain small forged, toughness is also higher.

(5) after high temperature and high pressure molding of billet temperature is very high, the surface covered with black carbide, must use the fork to prototype and motivation handling. After pickling surface treatment has been the hub of the forging wheel blank.

(6) after the long time reprocessing of two heat treatment machines of T4 and T6, the grain of the coarse embryo will be more compact and the toughness of the product will be improved.

(7) forged aluminum wheels must rely on mechanical processing, the blank is machined to the wheel molding, therefore including bead molding, screw hole drill, disk turning and detail processing steps.

(8) before the coating is applied, it is necessary to check the defect on the surface of the forged aluminum wheels.

(9) entering the coating line for coating. Make all kinds of colors.
