金属薄板开槽弯曲成形技术与设备

Metal Sheet Slotting & Bending Technique and Equipment

V形弯曲成形前 ,对金属薄板折弯处进行一定深度的V形开槽 ,然后在V形开槽处进行弯制成形 ,此种加工方法称之为V形开槽弯曲成形技术。用V形开槽弯曲成形技术弯制的工件弯曲圆角半径小 ,色泽变化不明显 ,弯制成形力小 ,且减少了窄长工件弯曲棱边直线度误差。并在普通折弯机上用通用模具就能弯制断面形状复杂的工件。V形开槽弯曲成形技术的关键设备是薄板开槽机 。

Before bending to V shape, the metal sheet should be slotted with V_shape of a certain depth on the bending line, then the metal sheet is bent to the required shape along the V_slot. This machining method is called bending forming technique with a V_slot. Through this method, the diameter of the bending circle angle of the workpiece is small, the color change is not very obvious, the bending and forming power is low and the straightness error of the bending edge of the workpiece with narrow and long size has been reduced. And also, the workpiece with complex section can be bent on the common bending machine using general mold. The key equipment for the bending technique with V_slot is slotting machine for metal sheet with multi_type constructions and controlling modes.
