Abstract

Pedal assembly metal plate (1) has four cylindrical collars (4) located on a surface (2) of the plate. The collars are intended for the placement of a soundproofing pad and are obtained by progressive stamping of the pedal assembly plate. The thicknesses of the plate and of the walls of the collars are substantially the same. An independent claim is also included for a method for production of the collars by progressive stamping, involving denting the place selected for location of a collar and successive operations of deforming the dent, sizing the final collar, and punching the collar.

Description

L'invention concerne une platine de pédalier en métal munie sur une face d'entretoises destinées à localiser la découpe d'un tapis insonorisant.The invention relates to a metal pedal plate provided on one side with spacers for locating the cut of a soundproofing mat.

De telles platines de pédalier sont notamment utilisées dans les véhicules.Such bottom brackets are used in particular in vehicles.

La publication EP 1 184 770 décrit une platine de pédalier dont les entretoises sont rivetées ou soudées à une platine de support, ou font partie d'un châssis qui est rapporté sur la platine.The publication EP 1 184 770 discloses a bottom bracket whose spacers are riveted or welded to a support plate, or are part of a frame which is attached to the plate.

La présente invention a pour but de réduire le coût de fabrication de ces platines.The present invention aims to reduce the manufacturing cost of these plates.

On y parvient selon l'invention en fabriquant les entretoises par emboutissage de la platine.This is achieved according to the invention by making the spacers by stamping the platen.

On emboutit la platine par passes successives telles qu'au final l'épaisseur de paroi des entretoises soit identique ou au moins sensiblement identique à celle de la platine.The plate is stamped by successive passes such that in the end the wall thickness of the spacers is identical or at least substantially identical to that of the plate.

Avantageusement, les opérations d'emboutissage provoquent un écrouissage qui renforce la dureté des entretoises.Advantageously, the stamping operations cause a work hardening which reinforces the hardness of the spacers.

Chaque entretoise est fabriquée par un procédé d'emboutissage progressif qui comprend une opération de création d'un enfoncement à l'endroit choisi pour la réalisation de l'entretoise, des opérations successives de déformation de l'enfoncement pour la formation progressive d'un collet par rétreint, une opération de conformation du collet final et une opération de poinçonnage en fond de ce collet.Each spacer is manufactured by a progressive stamping process which includes an operation of creating a depression at the location chosen for the realization of the spacer, successive deformation operations of the depression for the progressive formation of a collar by shrinking, a shaping operation of the final collar and a punching operation in the bottom of this collar.

La publication GB 1 136 500 décrit un procédé d'emboutissage par passes successives qui est mis en oeuvre à partir d'un flanc circulaire et qui n'est pas destiné ni adapté à la fabrication d'une platine de pédalier à partir d'une tôle.The publication GB 1 136 500 discloses a method for drawing in successive passes which is implemented from a circular flank and which is not intended or adapted to the manufacture of a bottom bracket from a sheet.

Dans un exemple typique du procédé de la présente invention, pour obtenir par emboutissage une entretoise ayant sensiblement la forme d'un collet cylindrique d'épaisseur sensiblement identique à celle de la platine, on réalise d'abord par emboutissage une demi-sphère de diamètre et de hauteur suffisamment supérieures au diamètre et à la hauteur du collet final pour que par passes d'emboutissage successives, on forme ensuite le collet voulu en modifiant progressivement le diamètre et la hauteur des collets intermédiaires et en augmentant progressivement l'épaisseur de paroi des collets.In a typical example of the method of the present invention, to obtain by drawing a spacer having substantially the shape of a cylindrical collar of thickness substantially identical to that of the plate, is first made by stamping a half-sphere diameter and height sufficiently greater than the diameter and the height of the final collar so that by successive stamping passes, the desired collar is then formed by progressively modifying the diameter and the height of the intermediate collars and by progressively increasing the wall thickness of the collars.

Par exemple, partant d'une platine d'épaisseur 2 millimètres on réalise d'abord par emboutissage une demi-sphère de diamètre 60 millimètres, de hauteur 20 millimètres ce qui conduit à une épaisseur de 1,68 millimètres pour la paroi de la calotte sphérique, et on transforme progressivement la calotte sphérique en un collet cylindrique, par passes d'emboutissage successives au cours desquelles on modifie les dimensions du collet pour obtenir au final un collet dont les dimensions sont : diamètre environ 20 millimètres, hauteur environ 15 millimètres, d'épaisseur de paroi environ 2 millimètres.For example, starting from a plate of thickness 2 millimeters is first made by stamping a half-sphere diameter 60 millimeters, height 20 millimeters which leads to a thickness of 1.68 millimeters for the wall of the cap spherical, and the spherical cap is progressively transformed into a cylindrical collar, by successive drawing passes during which the dimensions of the collar are modified to finally obtain a collar whose dimensions are: diameter approximately 20 millimeters, height approximately 15 millimeters, wall thickness about 2 millimeters.

Les figures du dessin joint, illustre un exemple de réalisation de l'invention :

  • La figure 1 est une vue en perspective d'une platine de pédalier connue à entretoises soudées ou serties ;
  • La figure 2 est une vue en perspective d'un pédalier selon l'invention, et
  • La figure 3 illustre les étapes successives du procédé de fabrication d'un collet d'entretoise.
The figures of the attached drawing illustrate an exemplary embodiment of the invention:
  • Figure 1 is a perspective view of a known pedal plate with welded spacers or crimped;
  • FIG. 2 is a perspective view of a pedal assembly according to the invention, and
  • Figure 3 illustrates the successive steps of the method of manufacturing a spacer collar.

On a représenté sur la figure 1 une platine de pédalier (1) en acier qui présente sur une face (2) quatre entretoises (3) constituées chacun par un corps cylindrique qui a été rapporté sur cette face par soudage ou sertissage.FIG. 1 shows a steel pedal plate (1) which has on one face (2) four spacers (3) each consisting of a cylindrical body which has been attached to this face by welding or crimping.

Sur la figure 2, on a représenté une platine de pédalier similaire mais dont les entretoises (4) ont été obtenues par emboutissage de la platine.In Figure 2, there is shown a similar pedal plate but whose spacers (4) were obtained by stamping the plate.

Dans cet exemple, on a utilisé un procédé d'emboutissage qui comprend les opérations suivantes schématisées sur la figure 3 qui montre en vues partielles des phases successives (A) à (I) de la formation d'une entretoise.In this example, a stamping process has been used which comprises the following operations shown diagrammatically in FIG. 3 which shows in partial views successive phases (A) to (I) of the formation of a spacer.

Ces phases comprennent :

  • (A) création d'un enfoncement (5) en forme de la calotte sphérique, par exemple de diamètre 60 millimètres et de hauteur 20 millimètres, pour que la matière de l'enfoncement soit suffisante pour fournir la matière du collet à obtenir ;
  • (B) déformation de la calotte sphérique pour le formage d'un collet (6), par exemple de diamètre 55 millimètres et de hauteur 20 millimètres ;
  • (C) transformation du collet (6) précédent en un nouveau collet (7), par exemple de diamètre 44 millimètres et de hauteur 21 millimètres ;
  • (D) transformation du collet (7) précédent en un nouveau collet (8), par exemple de diamètre 38 millimètres et de hauteur 21 millimètres ;
  • (E) transformation du collet (8) précédent en un nouveau collet (9), par exemple de diamètre 33 millimètres et de hauteur 22 millimètres ;
  • (F) transformation du collet (9) précédent en un nouveau collet (10), par exemple de diamètre 25 millimètres et de hauteur 22 millimètres ;
  • (G) transformation du collet (10) précédent en un nouveau collet (11), par exemple de diamètre 23 millimètres et de hauteur 18 millimètres ;
  • (H) transformation du collet (11) précédent en un nouveau collet (12), par exemple de diamètre 20 millimètres et de hauteur 18 millimètres ;
  • (I) transformation du collet à sa forme définitive, par exemple diamètre 20 millimètres et hauteur 15, 5 millimètres.
These phases include:
  • (A) creating a recess (5) in the shape of the spherical cap, for example of diameter 60 millimeters and height 20 millimeters, so that the material of the depression is sufficient to provide the material of the collar to obtain;
  • (B) deformation of the spherical cap for forming a collar (6), for example having a diameter of 55 millimeters and a height of 20 millimeters;
  • (C) converting the previous collar (6) into a new collar (7), for example having a diameter of 44 millimeters and a height of 21 millimeters;
  • (D) converting the preceding collar (7) into a new collar (8), for example having a diameter of 38 millimeters and a height of 21 millimeters;
  • (E) transformation of the preceding collar (8) into a new collar (9), for example having a diameter of 33 millimeters and a height of 22 millimeters;
  • (F) converting the previous collar (9) into a new collar (10), for example having a diameter of 25 millimeters and a height of 22 millimeters;
  • (G) transforming the preceding collar (10) into a new collar (11), for example having a diameter of 23 millimeters and a height of 18 millimeters;
  • (H) converting the previous collar (11) into a new collar (12), for example having a diameter of 20 millimeters and a height of 18 millimeters;
  • (I) transformation of the collar to its final shape, for example diameter 20 millimeters and height 15.5 millimeters.

Après formage du collet, on exécute une opération de poinçonnage en fond de collet.After forming the collar, it performs a punching operation at the bottom of the collar.

L'invention n'est pas limitée à cet exemple de réalisation.The invention is not limited to this embodiment.
