Definitions

  • This invention concerns to a method of amending the entry angle of dies for extruding solid aluminum shapes.
  • solid aluminum shape extruding dies with one or more deliveries are built using cut heights which differ according to the thickness of the shape and its distance to the center, in order to regulate the flow of metal and obtain the correct form and measurements.
  • Feeding antechambers have also been used to ensure a good union or weld between two consecutive extrusions.
  • Our method consists fundamentally in using alignment charts or mathematical formulas to determine the metal entry angle that must be formed between the shape's axis and the width of the feeder slot or antechamber cut into the front of the die for each cross-section of the shape, depending on its thickness and distance to the center.
  • the feeder antechambers may be cut into one or more steps, such that the edges of each step restrict the opening of the feeder angle at each point, or, with the correct means of mechanization, the inner walls of the chamber may even be cut into the previously calculated angle.
  • Figure 2a is a plan view of one of the symmetrical figures comprising a metal shape die.
  • Figure 2b is a section showing the contours of the steps in the feeder chamber as well as the measurements that determine the feeder angle.
  • Figure 3a is a plan view of one of the four symmetrical deliveries of a shape.
  • Figure 4 is a plan view of the antechamber and the location of the deliveries in the experimental process.
  • Figure 5 is a section of the metal entry angle.
  • Figure 6 is a plan view of the extruding chamber for one type of shape.
  • Figure 7 is a cross-section of the same chamber.
  • Figure 2a is a plan view of one of the two symmetrical figures forming a die for a shape to be used in window construction.
  • the feeder angles calculated with the aid of the alignment chart are marked over the drawing of the three steps that have been cut to form the feeder angle. Throughout the entire figure, the cut height is 2 mm.
  • This die was cut into an H-13 steel disk and, after tempering and grinding, said die was used to manufacture shapes, yielding a shape of the correct measurements and forms inside tolerances, at an extrusion rate of 60 meters per minute.
  • Figure 3a gives a plan view of one of the four symmetrical deliveries of a shape to be used for vertical curtain tracks.
  • plan view illustrates the three steps that, as they contour the shape, define the feeder angle of the antechamber which will supply aluminum to each point of the shape in the necessary quantities in order to regulate delivery and obtain the correct forms and measurements.
  • the cut height contouring the form of the shape is 1.5 mm. throughout the figure.
  • This four-delivery die was made of H-13 steel, tempered and ground, and used for extrusion in a 1600 M.T. horizontal aluminum press, producing from the very start excellent quality aluminum shapes with correct measurement tolerances and surface finish at a rate of 65 meters per minute.

Claims (3)

  1. "Méthode de correction des entrées d'angle dans des matrices pour l'extrusion de profils solides en aluminium", caractérisée par le fait de comprendre une sortie ou plusieurs, dans lesquels la régulation du flux du métal ajusté pour chaque partie du profil ou des profils est obtenue moyennant un angle d'entrée du flux de métal à chaque point du profil qui sera calculé en proportion inverse à l'épaisseur désirée pour ce profil de sorte que l'éraillure ajustant la forme de la figure, si elle existe, a la même longueur sur l'ensemble de la figure du profil.
  2. "Méthode de correction des entrées d'angle dans des matrices pour l'extrusion de profils solides en aluminium", selon la première revendication, caractérisée par le fait que la forme de la chambre d'alimentation ainsi que sa profondeur sont déterminées par cet angle d'entrée de métal ou d'alimentation et peuvent avoir un ou plusieurs échelons, par commodité d'usinage, les arêtes intérieures de ces échelons étant celles qui déterminent, avec l'axe du profil en chaque point, l'angle d'entrée, l'angle d'entrée sans échelons intermédiaires pouvant même, dans le cas limite, être taillé intégralement.
  3. "Méthode de correction des entrées d'angle dans des matrices pour l'extrusion de profils solides en aluminium", selon la première revendication, caractérisée par le fait que les hauteurs de frôlement ajustant la forme du profil soient les mêmes dans tous les points de la matrice, étant donné que dans notre système elles n'ont guère d'influence sur la régulation du flux du métal et elles peuvent varier à partir d'un affûtage à 20 millimètres ou plus. Les matrices sont donc construites de préférence avec des éraillures de 0,5 mm, 1mm ou 2 mm.
