工人从料堆中拿起一个切割过的板料；对其进行定向，将其在放在上下刀具之间

Workers picked up from a windrow on cut sheet; its orientation, which slides on the tool between the upper and lower, until it hits the stopper, and finally the upper mold down mechanism bent workpiece. <br>Means for folding the other channel: reclaim sheet, the direction and the position of the adjustment plate; sometimes inverted so that the sheet metal plate is bent toward the other. <br>This is hard work, especially for large, heavy metal plate, then need several people to deal with. Further, in the artificial high physical strength it is very easy to make mistakes. Manually operated accidentally put the wrong position may bend or form the wrong angle, or even completely forget the machine is working.

The worker picks up a cut plate from the pile, directs it, slides it between the upper and lower cutters until it touches the rear stop, and finally lowers the upper mold mechanism down the curved workpiece.<br>Making another bend means reretracting the sheet, adjusting the direction and position of the plate, and sometimes flipping the plate to bend the sheet toward another one. It's hard work, especially for large, heavy metal plates, which need several people to handle. Moreover, it is easy to make mistakes under high-intensity physical labor. A careless manual operation can misplace the bend or form the wrong angle, or even completely forget that the machine is working.

The worker picks up a cut sheet from the stack, directs it, slides it between the upper and lower cutters until it meets the rear block, and finally lowers the upper die mechanism to the bending workpiece.<br>Making another bend means reclaiming the sheet, adjusting the direction and position of the sheet, and sometimes turning the sheet over to make it bend towards the other side.<br>This is a hard work, especially for large, heavy metal sheets, which requires several people to deal with. Moreover, it is easy to make mistakes under high-intensity manual labor. Manual operation may misplace the bending position or form the wrong angle, or even completely forget that the machine is working.<br>
