2. Before the trial moulding, the extrusion center of the aluminum extrusion machine must be adjusted. The extrusion shaft, the ingot ingot, and the discharge port of the die holder should be on a center line.
Third, in the trial mode and normal production process, the aluminum rod heating temperature must be guaranteed between 480-520 °C.
Fourth, the aluminum mold mold heating temperature according to the conventional mold temperature, controlled at about 480 °C, diameter 200mm below the flat mold insulation time shall not be less than 2 hours, if it is diverter mold insulation in more than 3 hours; diameter of more than 200mm above the mold insulation 4 - 6 hours to ensure uniform core temperature and external temperature.
5. Before tryout or production, clean the cylinder liner with clean cylinder pad and check if the extruder is running normally.
Sixth, try mold or just start production, the extruder automatically shut off, the various paragraphs switch to zero. Starting from a small pressure and starting slowly, it takes about 3-5 minutes to discharge the material, and the aluminum controls the pressure during the 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 it can be slowly accelerated. In the normal production, the extrusion speed is less than 120Kg/cm2.
7. During the trial mould or production process, the aluminum alloy profile mould shall be shut down immediately if any phenomena such as blockage, partial toothing, and too fast or slow deviation are found, and the mold shall be unloaded in a manner to avoid mold scrap.
8. In the trial production or aluminum production process, the discharge port must be unobstructed, and the slip support or fixture should be properly grasped according to the discharge conditions. Observe the abnormal situation at any time, and deal with it in time, and immediately stop the machine during the shutdown.
Nine, straightening process, we must carefully test before and after the change, operating specifications, moderate force, strict product quality.
X. According to the aluminum production schedule, it requires a reasonable length. When sawing, the saw tooth feeding speed can not be too fast, to avoid injuring the end, the end must be clamped positively, remove the flash and burr.
Eleventh, aluminum alloy profile baskets should be standardized, including the pad to be placed reasonably, to avoid damage to the profiles.
Twelve, aluminum profile aging temperature control at 190 ± 5 °C, insulation 2.5-4 hours, after the air-cooling.
