Title:
三次元スイープユニットを備えるロール成形機及び方法
Document Type and Number:
Japanese Patent JP2013505140
Kind Code:
A
Abstract:
An apparatus includes a roll former with rolls configured to form a structural beam from sheet material, and a sweep unit for longitudinally sweeping a beam in any of vertical, horizontal, or combination directions. The sweep unit has a first pair of forming rolls positioned to engage first opposing sides of the structural beam and has a second pair of forming rolls positioned to engage second opposing sides of the structural beam. The sweep unit movably supports the first and second pairs of forming rolls so that any selected one of the forming rolls continuously engages an associated side of the structural beam while an associated one of the forming rolls opposing the selected one forming roll moves downstream and around the selected one forming roll. This provides a very stable beam-bending condition promoting dimensional stability during the sweeping process, and hence dimensional accuracy and repeatability.
