铝条折弯的工艺流程

The process flow of aluminum bar bending

设备上电后，通过触摸屏输入铝框图形参数，踩下脚踏开关设备开始运行，控制系统通过判断原料位置选择自动上料流程还是直接进入自动折弯流程，并自动判断当前原料的余料接头位置是否出现在禁折区。步进给料系统将由控制系统计算后的料长精确的给进至折弯刀头，由折弯系统完成需要的折弯形状。

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 remaining material joint position of the current raw materials is out of the current folding zone. The stepper feed system will accurately feed the material length calculated by the control system to the bending tool head, and the bending system will complete the required bending shape.

重复以上两步，直至完成整个铝框成形流程。

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

在铝框折弯过程中，随时会出现当前加工的铝条即将用完的情况，通过系统自动判断可使后续铝条自动续接至当前铝条尾部，不中断当前铝条的成形工作。

During the bending process of the aluminum frame, there may be situations where the currently processed aluminum bars are about to be used up. Through automatic judgment by the system, 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.
