[China Aluminum Industry Network] first analyze the process: 1. Before opening the aluminum extrusion machine, ensure that there is no debris or oil around the equipment and on the machine table. 2. Prepare raw materials according to production requirements and pour them into the material trough as required. 3. Check the power supply and confirm that the control cabinets are working properly. First, the industrial aluminum extrusion extruder can be divided into the following parts: 1. The transmission and extrusion system is controlled by the main frequency converter to control the frequency conversion speed control motor, through the gear box distribution box, the cross spline, and step by step transmission to the screw. The input program and parameter values ​​in the inverter are The device has been set at the factory and cannot be changed at will. 2. The heating and cooling system is composed of barrel heating and cooling, die heating and screw core heating and cooling. It is controlled by the electric chamber program. The B&R temperature module is combined with PID temperature control software to replace the traditional temperature control table and system. The PID parameters can be automatically optimized in the heating process. After the calculation is completed, the PID parameters can be automatically assigned, or the PID parameters can be manually assigned based on their own experience. The temperature control is accurate to ±°C. Its working principle is to give a temperature value such as 180°C in the heating section of each zone, and the data is measured by a thermocouple. As the temperature rises gradually with heating, the heating frequency gradually decreases, and the heating time also gradually decreases. When ≥180°C, the area starts to cool and the fan starts to work. (Cooling is divided into two types: air-cooled and oil-cooled) When ≤180°C, it starts heating again and again and again, and it reaches balance at the end. Core temperature cooling is the same reason, but its set temperature is lower at about 80 °C, and is through the heat transfer medium to heat transfer, when the temperature is less than or equal to 80 °C core heating pipe heating work, through the oil pump cycle to provide heat to the screw, When the temperature is higher than or equal to 80°C, the water supply solenoid valve of the cooler is opened, the oil is cooled by the cooler, and the excess heat in the screw is taken away through the oil pump circulation. The second, third and fourth zones of the barrel and the core temperature are automatically controlled, and another manual forced cooling function is provided to control the instantaneous temperature increase. 3. The automatic feeding system is controlled by the time relay or level meter to transmit signals. When the material is missing, the level meter transmits the signal and the system starts to feed the material. When the material is full, the level meter signal is interrupted and the material supply stops. 4. The feeding system is also controlled by a frequency converter controlled variable-frequency cycloidal pin gear reducer, the proportion of which is adjusted according to the rotation speed of the main engine screw. The current and torque of the main machine are directly affected by how much material is fed, and less feeding is required. Current and torque are reduced. On the contrary, it increases. When the feeding is too much and the actual current exceeds its rated current or the torque exceeds its set value, the host will overload the alarm and stop, generally controlling the rated value at 50%~80%. 5. The vacuum exhaust system is directly controlled by a button to control the vacuum pump. When the vacuum is opened, the solenoid valve is opened. When the vacuum valve is closed, the solenoid valve is closed. For industrial aluminum extrusion press products, they all have their own design parameters, such as extrusion weight, extrusion volume, and extrusion metal, and must not exceed the product design parameters during extrusion operations. For the drive of the industrial aluminum extrusion press, attention should be paid to the difference between single-screw and twin-screw industrial aluminum extrusion presses. Do not use it in disorder, otherwise it is easy to cause irreversible failure to the industrial aluminum extrusion press products. Second, the industrial aluminum extrusion machine operating procedures: 1. Check whether the oil pressure system leaks oil and whether the air pressure is normal. 2. Check if the conveyor belt, the cooling bed, and the storage platform are damaged and bruise the profile. 3, before stretching to confirm the length of the aluminum profile, and then pre-determined elongation rate, determine the stretching length, the main chuck movement position, usually 6063T5 stretching rate of 0.5% - 1%, 6061T6 stretching rate of 0.8% --1.5%. 4, according to the shape of the aluminum profile to confirm the clamping method, large-section hollow profile, can be inserted into the tensile pad, but to ensure enough clamping area. 5. When the aluminum profile is cooled to below 50°C, open the tensile profile. 6. When the profile is bent and twisted at the same time, it should be corrected after twisting and bending. 7. Pull on the front and the back to confirm that the pre-determined stretch rate and clamping method are appropriate. Visually bending, twisting, checking the plane gap of the profile, flaring, and paralleling, if inappropriate, adjust the stretch rate appropriately.
