Title
(EN) SHOT-TREATMENT APPARATUS
(FR) APPAREIL DE GRENAILLAGE
Abstract
(EN)
The present invention aims to provide a shot-treatment apparatus which allows a high throughput of workpieces with the least possible idle time while achieving a uniform shot-treatment effect on workpieces. The shot-treatment apparatus of the present invention has a rotatable main table 30 located in the place where both a projection area to be projected upon by the shot from a projecting device and a non-projection area are included. A plurality of satellite tables 32 for placing workpieces 12 are rotatably mounted on the main table 30. Each satellite table 32 has a driven shaft 33 which is in parallel with a main shaft 31 of the main table 30. The shot is projected from the projecting device against the workpiece 12 that is placed on the satellite table 32. The workpiece 12 that is placed on the satellite table 32 is held down by a holding member 48 of a holding assembly 46. The holding member 48 rotates along with the workpiece 12.

La présente invention a pour objectif la production d'un appareil de grenaillage qui permet un débit élevé de pièces avec le moins possible de temps mort tout en réalisant un effet de grenaillage homogène sur les pièces. L'appareil de grenaillage de la présente invention comporte une table principale rotative 30 située à l'endroit où se trouvent une zone de projection sur laquelle est projetée la grenaille depuis un dispositif de projection et une zone de non-projection. Une pluralité de tables satellites 32 destinées à placer des pièces 12 sont montées rotatives sur la table principale 30. Chaque table satellite 32 comporte un arbre entraîné 33 qui est parallèle à un arbre principal 31 de la table principale 30. La grenaille est projetée depuis le dispositif de projection contre la pièce 12 qui est placée sur la table satellite 32. La pièce 12 qui est placée sur la table satellite 32 est maintenue abaissée par un élément de maintien 48 d'un ensemble de maintien 46. L'élément de maintien 48 tourne avec la pièce 12.
