鋁條折彎的工藝流程

The process flow of aluminum bar bending

設備上電后，通過(guò)觸摸屏輸入鋁框圖形參數，踩下腳踏開(kāi)關(guān)設備開(kāi)始運行，控制系統通過(guò)判斷原料位置選擇自動(dòng)上料流程還是直接進(jìn)入自動(dòng)折彎流程，并自動(dòng)判斷當前原料的余料接頭位置是否出現在禁折區。步進(jìn)給料系統將由控制系統計算后的料長(cháng)精確的給進(jìn)折彎刀頭，由折彎系統完成需要的折彎形狀。

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.

重復以上兩步，直完成整個(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 )出現當前加工的鋁條即將用完的情況，通過(guò)系統自動(dòng)判斷可使后續鋁條自動(dòng)續接當前鋁條尾部，不中斷當前鋁條的成形工作。

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.
