The electrical control system is the core part of the entire equipment, and the control software of the equipment is installed in the MC motion controller. All control instruction calculations, input and output signal system status monitoring, as well as information exchange with operators, are completed by this section.

After the device is powered on, input the aluminum frame graphic parameters through the touch screen, press the foot switch, and the device starts running. The control system selects the automatic feeding process or directly enters the automatic bending process by judging the position of the raw materials, and automatically determines whether the position of the remaining material joints of the current raw materials is outside the prohibited folding area. The step feed material system will accurately feed the material length calculated by the control system to the bending blade, and the bending system will complete the required bending shape.

重復(fù)以上兩步，直至完成整個(gè)鋁框成形流程。

Repeat the above two steps until the entire aluminum frame forming process is completed.

在鋁框折彎過(guò)程中，隨時(shí)會(huì)出現(xiàn)當(dāng)前加工的鋁條即將用完的情況，通過(guò)系統(tǒng)自動(dòng)判斷可使后續(xù)鋁條自動(dòng)續(xù)接至當(dāng)前鋁條尾部，不中斷當(dāng)前鋁條的成形工作。

During the bending process of the aluminum frame, there may be situations where the current processed aluminum bars are about to be used up. The system automatically determines that the subsequent aluminum bars can be automatically connected to the tail of the current aluminum bar without interrupting the forming work of the current aluminum bar.
