在三芯卷板机上安装一套辅助模具,就能方便地弯制蛇形管(螺旋管)、环管及角钢等,而且弯曲半径在一定范围内可以任意调整,达到一机多用的效果。我厂应用这种辅助模具在φ200×1600mm卷板机上,成功地弯制了一批弯曲半径为200mm、螺距为70mm的蛇形管(材质为1Cr18Ni9Ti)。管径为φ34×3.5mm,弯曲半径误差小于±1.5mm,管子直径圆度误差小于0.15mm,质量符合图纸要求。一、模具结构该模具由三组分别装于卷板机上的带圆弧槽的圆筒组成。每组由两个
In the three-core coiling machine to install a set of auxiliary mold, you can easily bend the serpentine pipe (spiral pipe), pipe and angle, etc., and the bending radius within a certain range can be arbitrarily adjusted to achieve a multi-purpose machine. I plant the use of such auxiliary mold in φ200 × 1600mm Bending Machine, successfully bending a number of bending radius of 200mm, pitch 70mm serpentine tube (made of 1Cr18Ni9Ti). The pipe diameter is φ34 × 3.5mm, the error of bending radius is less than ± 1.5mm, the error of roundness of pipe diameter is less than 0.15mm, the quality conforms to the drawing requirements. First, the mold structure The mold by the three groups were installed in the rolling machine with a circular groove of the cylinder composition. Each group consists of two
