Definitions

  • the present invention relates to a washing machine, and more particularly, to a method for manufacturing dehydration adjustment holder of the washing machine.
  • a dehydration holder of a washing machine is coupled to a dehydration body as a shaft in the bottom of the dehydration body to thus be driven, as shown in FIG. 2 showing a method a holder according to the prior art, with hot forging working.
  • the prior art forging working is sequentially executed with material cutting working 10, heating working 20, first forging working 30, t- ⁇ riming and edge cutting working 40, reheating working 50, and second forging working 60, and machinelikely executed with shorting -blasting 70 for stripping oxidation skin surface generated due to the forging workings, plating working 80, shaft hole cutting process working 90 for coupling the shaft of the dehydration body. Also, it is finally executed with edge cutting working 100 by the molding.
  • the edge cutting working 50 performed prior to the second forging working 60 is necessarily required because the edge of the product made from the first forging working 40 is irregular and has problems such as environment pollution and the urgency in the health of workers, as the working for stripping oxidation skin surface of the material generated after forging working in the shorting-blasting 70 following the second forging working. Because the shaft hole process working 90 as machinelikely performed is divided into first and second forging workings, the prior art has problem in that the shaft hole process working 90 takes much time to be performed and the precision of the size is varied depending on the worker's skill.
  • FIG. 1 is a view showing a method for manufactuiing a holder according to the present invention.
  • FIG. 2 is a view showing a method for manufacturing a holder according to the prior art.
  • the above object can be achieved according to the present invention with a method for manufacturing a dehydration adjustment holder of a washing machine, including: a trimming and first molding working A for simultaneously shaping a center protrusion, a wing connected to the center protrusion, and a depression in the interior of the wing; a correction process B for making an upper surface of the wing to be flat while repeating diameter diminishment working and depth hardening working of the protrusion; a process C for making a penetrating space at the center of the protrusion while cutting and removing unnecessary edge of the diameter of the wing according to selected size; a wing correction process D for molding and constructing a hole a and a cutting unit-groove of the conventional wing; a recorrection process E for vertically making a protrusion portion at an end of the penetrating space, to be flated; and, a final cleaning and painting process E.

  • All processes of the present invention are performed with press molding working. Namely, the prior art forging working is selected for preventing the dirninishment of the pressure force at the shaft because the penetrating space 2', or, the end of the shaft tube is increased to be thin with the molding process and accordingly, terminals are open upon assembling the shaft.
  • the process according to the present invention is executed as an up setting process of hardening the diameter of the upper surface 1' of the protrusion 1 as a measure including a hardening process.
  • the tii-T-ming and first molding process A applies the pressure to the metal plate (material) supplied therein with the molding and molds a fundamental structure having the protrusion 1 and the wing 2.
  • the correction process B is performed as a previous process for molding the fundamental structure, with repeating diameter diminishment working and depth hardening working of the protrusion 1 depending on the selected requirements.
  • the above repeating workings are performed by considering the phenomenon of rapidly making the thickneee of the protrusion to be thin to thus be cracked in the case of suddenly climi-nishing the diameter of the protrusion 1.
  • the up setting process is performed with trimming the upper surface 1' of the protrusion 1, the upper surface 1' is finally molded to be flat. This is shown in the correction process of the diagrams of the present invention.

  • the molding having the diameter less than that of the penetrating space 2' is used in the process C, so that the protrusion portion la can be remained to be coupled and cut to the end of the interior of the penetrating space 2'.
  • the protrusion portion la is corrected with recorrection process E as will be described hereinafter.
  • the above state become the fundamental structure having the fundamental configuration and the construction elements of the present invention.
  • the wing correction process D molds and constructs the hole a and a cutting unit-groove b as necessary elements of the conventional wing 2 in the above fundamental structure.
  • the recorrection process E according to the present invention vertically can finally obtain the perfected products through the conventional cleaning and painting process while making a protrusion portion la generated upon molding the penetrating space 2' in the process C, to be flated and makes the coupling of the shaft to be intimate with each other.
  • the present invention has advantages in that the price of the product can be remarkably lowered as production in large quantities and the generation of inferior goods can be decreased with molding at the exact size because the repeating workings can be performed with adapting not the conventional forging working but the press molding working. As well, the size of the penetrating space 2' is exactly made with precision process, thereby maintaining good reliability of the product. Likewise, the present invention is for applying the pressure with using the metal plate, thereby contributing the production in large quantities and price cutting.

Abstract

Ce procédé de fabrication d'un support de réglage de déshydratation pour machine à laver comporte les étapes suivantes : (A), un détourage et un premier moulage permettant de former simultanément un saillant central, une aile rattachée au saillant central et une dépression située à l'intérieur de l'aile, (B), un travail de correction visant à aplatir la face supérieure de l'aile tout en diminuant, à plusieurs reprises, le diamètre du saillant et tout en durcissant celui-ci en profondeur, (C), une opération visant à constituer un espace de pénétration au centre du saillant, opération durant laquelle on coupe et on enlève de la matière sur le bord de l'aile pour arriver aux dimensions désirées, (D), un travail de correction de l'aile permettant d'y ménager un trou (a) et une encoche et, (E) un nouveau travail de correction visant à rendre verticale une partie du saillant à une extrémité de l'espace de pénétration, à aplatir. On nettoie ensuite la pièce et on la peint (F).
