Radiator production process
1. For the mold test of high-density teeth and large tongue ratio, the first aluminum rod must be a short aluminum rod or a pure aluminum rod of 150-200 mm. Second, before the test, the extrusion center must be adjusted, and the extrusion shaft, the ingot cylinder and the mold base discharge port are on a center line. Third, in the test mode and normal production process, the heating temperature of the aluminum rod should be guaranteed between 480-520 °C. 4. The heating temperature of the mold is controlled at 480 °C according to the temperature of the conventional mold. The flat mold holding time of the diameter below 200 mm is not less than 2 hours. If the split mold is kept for more than 3 hours, the mold holding the diameter is more than 200 mm. Hours to ensure uniformity of mold core temperature and external temperature. 5. Before the test or production, the cylinder liner must be cleaned with a clear cylinder gasket, and the empty operation of the extruder should be checked.
6. When the test mode or the beginning of production, the automatic cutting of the extruder is turned off, and the switches of each segment are returned to zero. Starting from the minimum pressure, the discharge is about 3-5 minutes, and the pressure is mainly controlled during the aluminum filling process. The pressure is controlled within 100Kg/cm2, the ammeter data is within 2-3A, generally 80-120Kg/cm2 can be discharged, and then slowly accelerated. The normal extrusion speed is less than 120Kg/cm2. 7. In the mold or production process, if the mold is found to be blocked, the teeth are too far, the deviation is too high, etc., the machine should be stopped immediately, and the mold should be unloaded in a way to avoid scrapping the mold.
8. In the test mode or production process, the discharge port must be unobstructed, and the pad support or the clamp looseness should be reasonably mastered according to the discharge condition. Observe the abnormal situation at any time and deal with it in time. Stop the machine immediately. Nine, in the process of straightening, it is necessary to carefully test the changes before and after, the operation specifications, moderate force, and strict product quality. 10. According to the production plan, a reasonable length is required. When sawing, the sawing feed speed should not be too fast, avoiding hurting the end, and the end must be clamped to remove the flash and burrs. XI. Packing baskets should be standardized, including the mats should be placed reasonably to avoid damage to the profiles. 12. The aging temperature of the profile is controlled at 190±5°C, and the temperature is kept for 2.5-4 hours. After the furnace is discharged, air cooling is performed.
