MANUFACTURE OF NOSE SECTION PARTICULARLY FOR VACUUM HANDLINGSYSTEM AND NOSE SECTION FORMED BY SAID MANUFACTURE

摘要

The object of the invention relates to the technical sector of the micro -. & br / according to the process starts with a hollow tube 1 of determined diameter stainless steel; it is shrunk the tube 1 on a certain length 1a and is flattened the remaining part so as to form two opposite plane faces that are not contiguous, 1b and 1c, are made in one of the flat sides 1b, a light 1b1 and in the other face 1c, a hole 1c1; it is introduced between the two faces, 1b and 1c a vane 2 having, on the basis of one of its edges, an axial notch 2a; it is flattened, the two flat faces 1b and 1c on the pallet stone 2; it is introduced through the hole 1c1 formed in one of the faces, a powder which is shaped so as to ensure a micro - brazing after heating, it passes the assembly in a furnace in order to ensure the assembling by welding of the blade 2 with the flat parts and, simultaneously, the filling of the micro - brazing of cavities left between the blades and the flattened portions; the rounds off the ends of the flat parts of the handle; it corrects the flattened regions. & br / (see appended drawing in bopi) & br / & & br /
