Definitions

  • the present invention relates to a method for producing an inner profile of a sleeve-like metallic outer part by circular kneading, the inner profile corresponding at least substantially to an outer profile of a metal inner part which can be inserted at least in sections in the longitudinal direction of the outer part in the region of the sections of the two parts which can be pushed into one another. Furthermore, the present invention relates to a method for producing an outer profile of a metallic inner part by circular kneading, the outer profile of an inner profile of a sleeve-like metallic outer part, into which the inner part can be inserted at least in sections in the longitudinal direction thereof, in the region of the sections of the two parts which can be pushed into one another, at least in the area essentially corresponds.
  • the sections of the part serving as a template, which are provided with the profiling have a greater hardness than the sections of the respective other part into or onto which a profiling is to be inserted or applied. In this way it is ensured that the profiling is transferred to the other part by the round kneading without significantly impairing the existing profiling.
  • a separating agent is arranged during the round kneading between the sections of the outer part and the inner part pressed together by the round kneading tool, oil, fat or a plastic coating preferably being used as the separating agent.
  • the release agent prevents the outer part and the inner part from being welded to one another during the round kneading.
  • the outer part and / or the inner part can perform an oscillating movement in the longitudinal direction during the round kneading.
  • This oscillating movement can be used in addition or as an alternative to the separating means in order to prevent welding of the outer part and the inner part during the round kneading.
  • the round kneading can be carried out cold, preferably steel can be processed. With other materials, such as magnesium, the outer part and the inner part are advantageously heated during the round kneading.
  • the inner part can either be a full professional! or be designed as a tube.
  • Fig. 1 is a schematic longitudinal sectional view through a device for

  • a device for carrying out a method for example for producing an inner profile 4 of a sleeve-like metallic outer part 1 comprises a metal inner part 2 which is at least partially pushed into the outer part 1 and which is provided in sections with an outer profile 5.
  • both the inner profile 4 and the outer profile 5 are designed as longitudinal teeth.
  • the outer profile 5 of the inner part 2 extends only up to a taper 6 of the inner part 2. The outer profile of the inner part 2 is previously applied to this in a known manner, for. B. by means of a pull ring.
  • an inner profile 4 in the outer part 1 it is advantageous to make the material of the inner part 2 harder than the corresponding area of the outer part 1, at least in the area provided with the outer profile 5.
  • hardened steel is the material of the inner part 2 and more normal Steel as the material of the outer part 1.

  • Fig. 1 the hammering radially oriented movement of the rotary kneading tool 3 is indicated by the arrow 8.
  • the contact surface 9 of the circular kneading tool 3 only acts on a longitudinal section of the outside of the outer part 1.
  • the inner part 2 can execute an oscillating movement in the longitudinal direction according to the arrow 7. There is still the possibility to let the outer part 1 oscillate in the same direction instead of the inner part 2. In addition, there is also the possibility of having both parts 1, 2 oscillate against one another in the longitudinal direction according to arrow 7.
  • a release agent can be used between the outer part 1 and inner part 2 in the area of the profiles 4, 5.
  • Oil, grease or a plastic coating of one or both parts 1, 2, for example, are suitable as release agents.
  • the separating agent can be used in addition or as an alternative to the oscillating movement in order to avoid welding the inner part 2 and outer part 1 together during kneading.
  • an outer profile 5 of the inner part 2 by inserting the inner part 2 into an outer part 1 which is already provided with an inner profile 4 and which is made of harder material in the corresponding section than the material of the inner part 2.
  • the inner profile 4 of the outer part 1 is then correspondingly transferred into an outer profile 5 of the inner part 1 by kneading.
  • Outer part 1 and inner part 2 form components for an automotive steering linkage after their manufacture.
  • the method according to the invention can be carried out both at ambient temperature and at elevated temperatures. It turns out that steel in particular can be processed cold, whereas magnesium, for example, can be kneaded better at higher temperatures.

Abstract

L'invention concerne un procédé pour la réalisation d'un profilage intérieur (4) d'une pièce extérieure métallique du type douille par rétreinte, ce profilage intérieur (4) correspondant au moins sensiblement à une partie intérieure (2) métallique insérable au moins par section dans le sens longitudinal de la pièce extérieure (1), dans la région des sections emmanchables des deux pièces (1, 2). Un profilage extérieur (5) peut être réalisé sur la pièce intérieure (2) qui s'insère au moins par sections dans la pièce extérieure (1). Un profilage intérieur (4) de la pièce extérieure (1) correspondant au profilage extérieur (5) de la pièce intérieure (2) est réalisé avec un outil de rétreinte (3) agissant de l'extérieur sur la pièce extérieure (1). En variante, le profilage intérieur (4) de la pièce extérieure (1) peut également être utilisé pour produire le profilage extérieur (5) de la pièce intérieure (2) au moyen d'un outil de rétreinte (3) agissant de l'extérieur sur la pièce extérieure (1).
