Definitions

  • the invention relates to the technical sector of the production of parts in cast alloys and in particular in aluminum, copper or others obtained in foundry, forging and similar processes.
  • foundry and forging techniques make it possible to manufacture multiple parts for various uses.
  • the foundry of cast alloys such as aluminum has the particular advantage of obtaining light parts while respecting the parameters and hardness criteria according to the applications considered.
  • These parts can be, for example, connecting rods for automobiles, cranks for cycle parts.
  • inserts made of metallic or other material are thus established, for example in the form of rings and which are introduced into the abovementioned openings of the part.
  • the alloy such as aluminum which while cooling ensures the maintenance of the insert.
  • This the latter may have ridges on its outer periphery or grooves for anchoring the material making it possible to stabilize the insert in the workpiece in position.
  • the use of the method is essentially limited to the installation on the part of a single insert. Indeed, the operation of casting the alloy and in particular the aluminum being carried out hot causes dimensional variations of the material and it is almost impossible to control with great precision the spacing of laying of several inserts.
  • the latter must be chosen from a material or material which is compatible with the temperature of the cast alloys and in particular of aluminum.
  • the aim sought after according to the invention was to remedy these drawbacks.
  • the applicant has also developed a process for manufacturing aluminum parts in foundries, in particular described in European patent n ° 119365.
  • This process consists in making foundry blanks which are subjected to cold or low temperature to an additional pressing operation, said blanks being arranged in the matrix imprints of dimensions substantially smaller than those of the molding.
  • the method consists in that after completion of the blank of the part to be obtained, there is arranged one or more inserts capable of being centered and introduced into the opening (s), and / or the recess (s), and / or the blind hole (s) formed previously on the blank, said inserts being prepositioned on a working die, and in that a punching operation is then carried out by a punch or similar means allowing the final shaping of the part to be obtained and the deformation of the material with a view to fixed and permanent integration by crimping the insert (s) in order to define local reinforcement zones according to the needs and the applications and uses of the part obtained.
  • the method according to the invention consists in manufacturing parts produced in the foundry of cast alloys and in particular aluminum of all shapes and profiles suitable according to the applications by producing blanks referenced as a whole by (1).
  • a blank is shown in Figure 1, and includes example a through opening (1.1) and a blind hole (1.2). It is obvious that said blank can have several through openings and / or several blind holes. The profile and dimensions of the openings and / or blind holes are established in any suitable manner according to the needs and criteria of application of the rough parts.
  • the blank can also have any recess on one of its faces of any shape and profile required.
  • the blank thus has a preset length (L) and a preset thickness (E).
  • the openings and / or holes and / or recesses advantageously have a substantially conical internal profile of a few degrees at an angle ( ⁇ ) to allow prepositioning of the blank and the reception of one or more inserts (2) of complementary profile. arranged and presented beforehand on a work receiving matrix (3). This matrix is established in any way and appropriate profile according to the shapes of the worked blank.
  • Said matrix is thus arranged directly or in an attached manner with one or more fingers (4) for centering and receiving the inserts (2).
  • the latter are mounted with play or floating around said finger (s) (4).
  • the matrix can be directly shaped to allow centering and positioning of the inserts (2).
  • the inserts are positioned on the fingers or directly on the die manually by the operator or also in the context of manufacturing automation with manipulators and all appropriate means ensuring their transfer from a dispensing bowl or similar means.
  • FIG. 3 There is shown in Figure 3 the positioning of the blank in the matrix, said blank being adjusted by the opening (s) and the blind hole (s) with free adjustment.
  • the blank is centered in a cavity established on the working die, being of dimensions substantially smaller than the internal profile thereof.
  • the method according to the invention then consists in exerting a striking operation on the blank using a punch (5) or similar means by exerting this force according to the arrow F arranged axially in the same plane as that of laying inserts.
  • the blank of the treated part is thus deformed and the material comes to surround said inserts while ensuring their final connection by crimping.
  • the finished part is then of a dimension (L1) substantially greater than that (L) of the blank, and its thickness (E1) is substantially less than that (E) of the blank.
  • the part obtained integrates the inserts in the above-mentioned opening (s) and / or the blind hole (s), and / or the recesses (not shown).
  • the insert can be established in the form of a ring having a collar (2.1).
  • the ring is of height (H) substantially less than the thickness (E1) of the finished part; thus said ring is held by the material both at the level of its zone presenting the collar, as well as in its bottom part.
  • said insert has a bottom face (2.4).
  • the ring may have circular ridges (2.2) arranged along its outer periphery under all or part of its height.
  • the ring can also have one or more longitudinal grooves (3) established over all or part of its periphery. These striations and grooves thus constitute means for anchoring the blank material resulting from the deformation thereof during the striking operation.
  • the shape of the insert (s) is unlimited and inserts of different shape can be placed on each part to be obtained.
  • the insert (s) can be made of any metallic, composite or other material.
  • the punch When the striking operation has been carried out, the punch is raised by any appropriate means and the finished part is ejected in order to carry out a new operating cycle.
