Industrial aluminum profiles extrusion process attention elements:
①Temperature control: For extrusion production, extrusion temperature is a basic and key process factor. Extrusion temperature has a great impact on product quality, production efficiency, die life, energy consumption, etc.
②Extrusion speed: The extrusion speed must be carefully controlled in the extrusion process of aluminum profiles. The extrusion speed has an important influence on the thermal effect of deformation, the uniformity of deformation, the recrystallization and solid solution process, the mechanical properties of the product and the surface quality of the product.
③On-machine quenching: 6063-T5 quenching is to keep the Mg2Si solid dissolved in the base metal at high temperature out of the die hole and quickly cooled to room temperature. The cooling rate is often proportional to the strengthening phase content. The minimum cooling rate that 6063 alloy can strengthen is 38°C/min, so it is suitable for air-cooled quenching. Changing the fan and fan revolutions can change the cooling intensity, so that the temperature of the product before tension straightening drops below 60°C.
There will be a certain deviation after extrusion of aluminum profiles. After forming, a straightening machine should be used for straightening and correction. The industrial aluminum profiles that have just been extruded should be corrected within the required tolerance range. to complete and ensure its accuracy.
