Method and device for profile bending

摘要

A method and a device are provided for the planar and spatial bending of rod-shaped components (2) having a longitudinal axis, such as pipes and profiles, including two roller systems A and B that are disposed behind each other along the longitudinal axis, wherein the component is driven by the roller system A and inserted into the roller system B, and is bent by a movement of the roller system B in a transverse direction to the longitudinal axis of the rod-shaped components (2). A device is also provided for the planar and spatial bending of rod-shaped components (2) having a longitudinal axis, such as pipes and profiles, including two roller systems A and B, wherein feed along the longitudinal axis can be effected via the roller system A, and the roller systems A, B are disposed in at least one first plane E1 in a displaceable manner relative to each other, wherein at least one of the roller systems A, B can be pivoted about the longitudinal axis.

1. A method for planar and spatial bending of a rod-shaped component having a longitudinal axis using a device having first and second roller systems (A and B) disposed along the longitudinal axis, wherein said first roller system (A) comprises a plurality of transport rollers and said second roller system (B) comprises a plurality of bending rollers, the method comprising steps of:
driving the rod-shaped component by the first roller system (A) to insert the rod-shaped component into the second roller system (B) and to transport the rod-shaped component through the first and second roller systems (A and B), moving the second roller system (B) in a transverse direction to the longitudinal axis of the rod-shaped component, and thereby changing a position of the first and second roller systems (A and B) relative to each other while the rod-shaped component is being transported by the first roller system (A) through the first and second roller systems (A and B), to bend the rod-shaped component within a bending zone between the first and second roller systems (A and B), and pivoting the roller system (A) relative to the roller system (B) about the longitudinal axis of the rod-shaped component, and thereby superposing torsional moments on the bending zone between the first and second roller systems (A and B) during the bending of the rod shaped component.
