How to use hub spinning die
1. The blank preheated by induction furnace is fixed on large-scale high-speed spinning equipment, and after the blank is matched with its special inner cylinder die, spinning forming begins.

2. The large-scale high-speed spinning equipment starts to rotate at high speed, and the secondary heating equipment is started to keep the spinning rim part at a constant temperature, and at the same time, the high-pressure wheel is started to rotate, so that the rim is strongly squeezed under the double pressure of the special mold matched with the special inner cylinder, and the blank rim part is stretched and formed into the initial rim shape.

3. Keep the high-speed rotation and high-temperature protection molecules from being pulled, and repeatedly rotate and stretch the rim under high pressure, thus forming a high-strength rim thin wall and reaching the pre-designed size specifications.

4. Adjustment speed: thin-walled rims are finely formed from top to bottom. The whole process of rim modeling is to improve the crystal structure of aluminum alloy more compact, the molecular structure more refined and fibrous, and effectively improve the elongation, tensile strength and yield strength of the material.
