(ロールフォーミング)により。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bending machine for bending and processing long plate materials. Currently, bending of long products of about 10,771 is mainly done by rolling bending (roll forming) in the case of small-variety, high-volume production.
また多棟少量生産ではプレスブレーキを用いた曲は加工
が行なわれている。In addition, in multi-build, low-volume production, songs are processed using press brakes.
またロールを用いる手段として特開昭58−12531
8号公報に示されたように1曲は線長さ方向にロールに
て順次部分的に曲けるようにした技術も公知である。Also, as a means of using a roll, JP-A-58-12531
As shown in Japanese Patent Application No. 8, a technique is also known in which one curve is sequentially partially bent by a roll in the length direction of the wire.

要であり、かつロールの汎用性に欠けるため同一の曲げ

一方プレスブレーキによる曲は加工は、型交換は比較的
容易で汎用性が高いといえるが、曲げ線が長い場合、大
きな成形荷重を必要とし、特に長尺、高張力。Problems to be Solved by the Invention Of the above conventional techniques, rolling bending requires very large equipment and the rolls lack versatility, so there is little cost benefit unless the same bending is performed in large quantities.
On the other hand, bending with a press brake is relatively easy to change molds and can be said to be highly versatile, but if the bending line is long, a large forming load is required, especially for long lengths and high tension.
板厚大では大きな成形荷重が必要で設備費が犬となると
いう問題があった。There was a problem with large plate thicknesses, which required a large forming load and increased equipment costs.

った。(2) In addition, in the conventional example shown in Japanese Patent Application Laid-Open No. 125318/1983, the curve is partially processed along the line direction, so there is a problem that the phase change is low for the curve over the entire length. As for the bending shape, there was a problem in that the cross-sectional shape could only be arcuate because the rollers rolled in the curved direction.
