Abstract
Matrice conçue pour réduire efficacement ou supprimer les contraintes de traduction auxquelles certaines de ses parties sont soumises lors de l'application d'une charge dans sa cavité. Un élément 14 de support est placé sous le fond 20 de la matrice 10 de manière que cette dernière ne repose initialement que sur une zone centrale de l'élément 14, et que sous la charge exercée par le poinçon 16 et transmise par la pièce 18 formee, le contact entre la surface inférieure 44 de la matrice 10 et la surface supérieure 46 de l'élément 14 s'étende radialement vers l'extérieur et fasse apparaître dans la matrice 10 des contraintes de signes opposées à celles appliquées directement par le poinçon I . Application: Production de pignons d'engrenage.A die designed to effectively reduce or eliminate the translational stresses to which some of its parts are subjected when applying a load to its cavity. A support element 14 is placed under the bottom 20 of the die 10 so that the latter initially rests only on a central zone of the element 14, and that under the load exerted by the punch 16 and transmitted by the part 18 formed, the contact between the lower surface 44 of the die 10 and the upper surface 46 of the element 14 extends radially outward and causes the matrix 10 to appear stresses of signs opposite to those applied directly by the punch I. Application: Production of gear wheels.
