The invention relates to a device for bending profile members in which the bending head includes at least one stage for bending the profile members and cutting the profile members after bending, provided with a tool for cutting the profile members including a pre-cutting member suitable for starting the cutting of the profile members, and a cutting member suitable for finishing the cut started by the pre-cutting member.

Device for bending profile members comprising tools for bending profile members and a tool for cutting said profile members

The invention relates to a device for bending profile sections, comprising at least one bending form () centered on a bending axis, provided with a peripheral groove that is interrupted by a cutout, a stack of clamping jaw counterparts (-) each comprising a cavity for clamping the profile section and having a shape designed to fit into the cutout of each bending form () with the cavity extending in the continuity of the peripheral groove of said bending form, means (-) for the so-called vertical movement of the stack of clamping jaw counterparts (-) which means are designed to move said stack along an axis parallel to the bending axis, a stack of clamping jaws (-), comprising cavities that complement the cavities of the clamping jaw counterparts (-), and means (-) for the relative movement of the assembly made up of the bending form(s) (), the stack of clamping jaw counterparts (-) and the stack of clamping jaws (-).

Device for bending profile sections such as tubes

The invention relates to a method for producing a jig (M) for the thermal forming and/or inspection of a tube (T) of neutral axis (x) and comprising a bent sections (c-c) connected by straight sections (d-d). The method consists in producing n individual jigs (M-M) each comprising a section of duct (') of planar neutral axis (&#x3c7;) for guiding a tube segment formed by one of the n bent sections of the tube (T) and by a predetermined length of each of the straight sections (d-d) extending from said bent section, said predetermined length corresponding to either all or part of the length of the straight section; and assembling the n individual jigs (M-M) with the sections of guide duct in the continuation of one another and with a relative orientation of the individual jigs adapted to provide a relative orientation between the n planes defined by the neutral axis (&#x3c7;) of the n sections of guide duct (&#x2032;) that is identical to the relative orientation between the n bending planes (P, P, P) defined by the n bent sections (c-c) of the tube (T).

The invention relates to a template for checking the geometry of shaped and/or bent profiles (T) having rectilinear sections and bent sections. This template comprises a support plate (), in which holes (-) are provided, and a superstructure comprised of, for each rectilinear section of the profile, a bracket () and at least one reinforcement () consisting of planar plates provided with lugs () adapted for being inserted into the holes (-) of the support plate () and of assembling means () that permit said bracket and reinforcement to be fit together in a position in which they extend perpendicularly. In addition, each bracket () is provided with at least one guiding element () of the rectilinear section of the profile (T).

Machine for bending or cambering a profile section, and bending head

In order to displace a working tool at a constant speed over a surface having a random shape and orientation, particularly for cleaning, pumicing, painting or decorating the outer surface of an aircraft, an autonomous moving body with a special design is used. This moving body comprises two attachment assemblies (10,12) each equipped with attachment members (30,48) which can be moved towards and away from the surface, and a tool holder assembly (14), said three assemblies being able to move with respect to the surface in a given direction. Control means supported by the tool holder assembly (14) ensure both the advance at a constant speed of said assembly with respect to the attachment assembly (10,12) fixed to the surface and the advance in the same direction and at a higher speed of the other attachment assembly, the two attachment assemblies (10,12) being in turn fixed to the surface without stopping the tool holder assembly (14).
