ABSTRACT:
The constructional parts have walls formed of elongated elements, such as res or tubes, wound spirally in juxtaposition about the axis of symmetry of the part and connected to each other. The elongated elements are bent to shape utilizing a bending device having at least one bending groove conformable to the predetermined three-dimensional geometry of the part to be manufactured. One end of each wire or tube is fixed to the bending device and the other end is engaged in a clamping and adjusting device designed as a combined Cardan swivel joint which, during the bending, it utilized to continuously control the adjustment parameters of the wire or tube, about three mutually intersecting axes, in conformity with such predetermined three-dimensional geometry of the part. The bent elements are then assembled in juxtaposition on an assembly core, separate from the bending device, having an external contour identical with the internal contour of the finished part, and the opposite ends of assembled juxtaposed elements are clamped against movements. The juxtaposed elements are then wrapped with a wire winding extending completely over the juxtaposed elements. The wire winding is then removed, by sectors or zones or areas, and the thus-exposed juxtaposed elements are then secured to each other, in the exposed zones, as by welded seams, to form the finished constructional part when the wire wrapping has been completely removed and all of the juxtaposed elements have been secured to each other.
