为了矫正造纸机械中的无缝钢管零件,我们试制了一台简易滚挤矫正专用设备。经多年使用,效果较好。工作原理(见附图a)。先将无缝钢管置于对开式夹具中,并紧固螺栓,由电动机驱动减速箱,使传动方杆作低速旋转,带动锥度心轴,滚柱通过锥度心轴表面的线接触作反向旋转,同时也使保护挤壳随之转动。由于三个支滚柱均有引入角λ,故锥度心轴、滚柱、对开式调节垫片、挤壳的组合体边旋转边自动向前,即可对管壁进行滚挤,迫使钢管内、外壁发生形变,从而达到矫正的目的。
In order to correct the seamless steel pipe parts in the papermaking machinery, we tried out a special equipment for easy roll-off correction. After years of use, the effect is better. Working principle (see figure a). First seamless steel pipe placed in the fixture, and tighten the bolt, the motor drive gearbox, so that the transmission rod for low speed rotation, driven taper mandrel, the roller through the taper mandrel surface line contact for reverse Rotation, but also to protect the crush shell rotation. As the three support rollers are introduced angle λ, so the taper mandrel, roller, open adjustment gasket, squeeze shell combination of body edge while rotating automatically forward, you can squeeze the wall of the tube to force the steel pipe Internal and external wall deformation, so as to achieve the purpose of correction.
