Definitions

  • the present invention relates to a process for coating rolls of composite material used for supporting and transferring continuous plies of small thickness and large width.
  • the present invention now aims to propose a new method which makes it possible to solve the aforementioned problem.
  • the liner part is stretched a first time before being assembled on the part to be coated.
  • the step iii) mentioned above is a stretching step.
  • FIG. 1 there can be seen an elongated part, of constant section, in accordance with the present invention, comprising a base body 10 of composite material and an external lining part 12.
  • the base body 10 is tubular and centered on an axis 11.
  • the base body 10 has a cylindrical straight section of revolution around the axis 11.
  • the base body 10 is made of composite material, for example a mixture of resin and glass or carbon fibers.
  • the lining part 12 is an external lining part. It is produced separately from the base body 10. These dimensions and tolerances are adapted to allow engagement, without any particular operation, of the external casing part 12 on the base body 10.
  • the casing part 12 can be produced according to any technique classic suitable. It can be formed of any material capable of being cold drawn, such as for example, stainless steel, carbon steel, copper, aluminum, or any equivalent material.
  • the lining part 12 is typically produced by rolling, welding and then stretching. It can also be carried out by machining and drawing, or simple machining.
  • the thickness of the lining piece 12 can be of the order of 1 to 5 / 10ths of a mm.
  • this operation iii) is a re-stretching operation, if the lining part 12 has been stretched before assembly on the base body 10.
  • FIG. 1 the drawing mandrel 20 engaged in the base body 10 and the necking die 30.
  • a disc 14 transverse to the axis 11 can be distinguished in FIG. 1 temporarily welded to the part. outer liner 12, at the front end thereof, by which the part is engaged in the necking die 30.
  • the disc 14 serves as a piston for the drawing mandrel 20.
  • the disc 14 can also serve as a piston to a fluid circuit, preferably an oil, high pressure 40 introduced into the internal channel 22 of the drawing mandrel 20 after completion of the operation iii) drawing, to separate the lined piece 10 and the mandrel 20.
  • a fluid circuit preferably an oil, high pressure 40 introduced into the internal channel 22 of the drawing mandrel 20 after completion of the operation iii) drawing, to separate the lined piece 10 and the mandrel 20.
  • the necking die 30 and the drawing mandrel 20 are made of any suitable conventional material.
  • the necking die 30 is advantageously made of carbide.
  • the cold drawing operation is conventional in itself and will therefore not be described in more detail below.
  • the cold drawing operation of the liner part 12 on the base body 10 is completed by an additional bonding between the liner part 12 and the base body 10. For this, it suffices to glue the base body 10 or the lining part 12 or both before the operation iii) of stretching.
  • FIG. 1 previously described illustrates the cold stretching or re-stretching operation used to fix an external coating 12 on a base body 10, in order to produce rolls for supporting continuous plies of large width.
  • the Applicant proposes to produce in the rollers, longitudinal grooves serving for the evacuation of the air.
  • These longitudinal streaks are preferably produced using a re-stretching operation on the jacketed piece 10, using a drawing die having internal ribs complementary to the desired streaks.
  • the aforementioned disc 14 can be used as a piston for the drawing mandrel during this new drawing operation.
  • the present invention can in particular find application in the coating of parts of great length, typically several meters and of large diameter, typically several hundred millimeters.
