The aluminium extrusion c
The aluminium extrusion can be divided into the following parts:
 |  |
1. Transmission and extrusion system is controlled by the main inverter to control the variable frequency speed regulating motor. It is completed by the gearbox distribution box and the cross spline, and is transmitted to the screw step by step. The program and parameter values entered in the inverter are in The device has been set at the factory and cannot be changed at will.
2. Heating and cooling system is composed of barrel heating and cooling, die heating, screw core heating and cooling, controlled by electric cavity program, manual operation according to their own experience, and a manual forced cooling function. Control the temperature of the moment to increase.
3. The automatic feeding system is controlled by the time relay or the level gauge to transmit the signal. When the aluminum profile manufacturer loses the material, the material level meter transmits the signal, the system starts to supply, and the material level meter signal is interrupted after the supply is full.
4. The feeding system is also controlled by the inverter, with less feeding and lowering of the main current and torque. Otherwise it rises. When the feed is too much, the actual current exceeds its rated current or the torque exceeds its set value. The host will overload and stop the alarm, generally controlled at 50%~80% of the rated value.
5. The vacuum exhaust system is directly controlled by the button to control the vacuum pump. When the vacuum is opened, the solenoid valve is opened, and when closed, the solenoid valve is closed.
