The four sided bending machine is sometimes referred to as a flexible bending machine, and its working principle is as follows:

（1）設定保壓時間，卸壓時間，水平擋料進退距離，調整好數控板料折彎機水平擋料位置。

(1) Set the holding time, unloading time, horizontal blocking distance, and adjust the horizontal blocking position of the CNC sheet bending machine.

（2）設定數控板料折彎機工步數以及每個工步的擋料位置、折彎張數。

(2) Set the number of steps for the CNC sheet metal bending machine, as well as the blocking position and bending number for each step.

（3）選擇連續操作檔位，下壓折彎機構不在上行程開關位自動回上行程開關位；踩下腳踏慢進，下壓折彎機構自動下壓；碰下行程開關時，水平擋料機構后退設定距離，同時自動進行保壓；數控板料折彎機保壓時間到自動進行卸壓，卸壓時間到下壓折彎機構自動回程，同時水平擋料機構自動前進設定距離；碰上行程開關，一次折彎動作結束，進行下一次折彎。

(3) Select the continuous operation gear, and the downward bending mechanism will first automatically return to the up travel switch position when it is not in the up travel switch position; Step on the foot pedal to slowly move forward, and the downward bending mechanism will automatically press down; When the down travel switch is touched, the horizontal material blocking mechanism retreats to the set distance and automatically maintains pressure; The CNC sheet metal bending machine automatically unloads the pressure when the holding time is reached, and the downward bending mechanism automatically returns when the unloading time is reached. At the same time, the horizontal blocking mechanism automatically advances to the set distance; Touch the travel switch, one bending action ends, and proceed to the next bending.
