METHOD AND APPARATUS FOR SUPPORTING A ROLL MOLDING MACHINE STAND, AND METHOD AND APPARATUS FOR MEASURING A SUPPORTING PLATFORM POSITION-Patent application

摘要

The present invention relates to a roll mill which is capable of arbitrarily setting the height and inclination angle of a cluster roll in which a plurality of rolls are successively arranged like a sliver roll in a roll molding machine such as a pipe mill, A method of supporting a molding machine stand, an apparatus therefor, and a control method, wherein a plurality of side rolls are held by a roll bracket to support a pair of cluster flat frames loaded with a common bed as a jack, In addition, the positions at both ends of the link are fixed so as to form an arbitrary triangle on the flat frame and the head plane, the length is measured by a linear encoder disposed along the link, and the measurement results obtained by converting the length into a Cartesian coordinate system , The current position information and the target position information are compared with each other The length of the link is changed to adjust the extension and contraction length of the forming pass line so as to freely set the vertical direction and the lateral direction of the forming pass line and the direction in contact with the material and the horizontal roll rotationally driven in the side roll group is arranged The roll spacing of the side rolls is not increased and there is no deterioration of the moldability caused by the buckling phenomenon of the end portion to be molded and it is most suitable for manufacturing a pipe having a thin plate thickness in which distortion should be avoided.
