Abstract
Official abstract text for this publication.
A bent product having a three-dimensionally bent portion intermittently or continuously in the lengthwise direction is manufactured by supporting a steel pipe at a first position A while feeding it in the lengthwise direction, locally heating the steel pipe being fed at a second position B, cooling the heated portion of the steel pipe at a third position C, and varying the position of a gripping means, which grips the steel pipe in a region ID downstream of the third position C, in a three-dimensional direction including the feed direction of the steel pipe in a workspace including a space on the upstream side of the third position C in the feed direction of the steel pipe to impart a bending moment to the heated portion of the steel pipe.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for manufacturing a bent product characterized by comprising, in combination, a feed device for feeding a long metal material in its lengthwise direction, a support means for supporting the metal material being fed at a first position, a heating means for locally heating the metal material being fed at a second position downstream of the first position in the feed direction of the metal material, a cooling device for cooling the portion of the metal material being fed which was heated at the second position at a third position downstream of the second position in the feed direction of the metal material, a chucking mechanism which moves in a three-dimensional direction while gripping the metal material in a region downstream of the third position in the feed direction of the metal material, and an articulated robot having six axes with the chucking mechanism fixed at a free end.
