Definitions

  • the invention further relates to a friction element and a device for carrying out the method according to the invention.
  • Fig. 1 shows two plate-shaped, superimposed workpieces 1 and 2, which can be, for example, sheets or parts of hollow profiles to be connected to one another. The two parts are firmly pressed together. However, it is not necessary to treat the surfaces of the workpieces 1 and 2 in the area of the joining or contact zone 3 specifically, to remove rolled or oxide skins or the like, as is required for spot welding, since the joining mechanism is completely different.
  • a device, not shown, for executing the method according to the invention is described in claims 12 and 13. Since the heat generated by the rotation or relative movement of the friction element relative to the workpieces decreases with increasing plasticization of the material and the associated decrease in the coefficient of friction, it is expedient to provide a speed control of the friction ram depending on the feed path or speed and / or contact pressure . In this way, an optimal and reproducible material temperature can be achieved during the connection process, and the time required to establish a connection can also be minimized.

Abstract

L'invention concerne un assemblage de deux pièces métalliques, obtenu par placage d'une première pièce contre la zone d'assemblage d'une pièce de base et par application sur la première pièce d'un élément de friction qui se déplace par rapport aux deux pièces dans le sens de la zone d'assemblage. L'élément de friction pénètre à travers la première pièce en produisant une masse fondue et refoule cette masse fondue au niveau de la zone d'assemblage après quoi, l'élément de friction est retiré de la liaison. Les deux pièces sont ainsi assemblées au niveau de la zone d'assemblage par une soudure par friction.
