(2)弯曲角度要准确。

(3)在弯曲处的外表面要平整、圆滑、没有皱纹和裂纹。

(4)如装沙弯制,应彻底清除内部的沙子。

(5)管子如果沿轴线方向的接缝,应将接缝放在中性层处,以免管子煨弯处的变形。

The bending of sheet metal in sheet metal processing should meet the following 5 basic requirements after bending.

(1) no significant elliptical deformation is allowed at the cross section of the bending point.

(2) the angle of bending is accurate.

(3) the outer surface of the bending surface should be smooth, smooth, without wrinkles and cracks.

(4) if the sand is bent, the internal sand should be thoroughly removed.

(5) if the joint of the pipe is along the axis, the joints should be placed in the neutral layer so as to avoid the deformation of the pipe.
