튜브형 line mixer용 element의 비틀음 성형에 대한 연구

study on twist forming of elements for tube type line mixers

  • 발행 : 1996.06.01

초록

the process of strip twisting is practiced for the manufacture of some commercial parts such as elements for tube type line mixers. A thin metal strip with rectangular cross section is twisted thru an angle greater than 180。. Initial geometry is altered in to a complex one with dimen-sional changes. In practice several tryouts are necessary to obtain required dimensional accu-racies. A simple analysis model is proposed to predict the dimensional changes forming torque and axial force.
