Abstract
Description
La pénétration de la concurrence étrangère nous oblige à rechercher la réduction des coûts de fabrication pour assurer la survie des entreprises donc de l'emploi en France. Cette constatation générale s'applique plus particulièrement à la fabrication de-s masques de soudure dont la technologie élémentaire autorise une copie facile et les nombreuses manipulations un attrait supplémentaire. The penetration of foreign competition forces us to seek the reduction of manufacturing costs to ensure the survival of businesses and therefore employment in France. This general observation applies more particularly to the manufacture of welding masks whose basic technology allows easy copying and many manipulations an additional attraction.
Le présent brevet a pour objet la description d'un transfert assurant d'une manière automatique les différentes opérations transformant la "carcasse11 en masque définitif. The object of the present patent is to describe a transfer automatically ensuring the various operations transforming the carcass into a definitive mask.
Le transfert automatique pour masque à soudure est constitué de deux paires de roues dentées montées sur axes libres (A1 et A2) entre lesquel-les circulent deux brins de channes à rouleaux < B-) qui supportent des coquilles (D) destinées à recevoir les carcasses (K). The automatic transfer for welding mask consists of two pairs of toothed wheels mounted on free axes (A1 and A2) between which two strands of roller shafts <B-) which support shells (D) intended to receive the carcasses (K).
Cet ensemble de chaînes (B) supportant les coquilles (D) est poussé vers l'avant par un vérin (E) dont l'extrémité porte un cliquet (F) qui prenant appui sur le fond de la coquille (D) lui fait parcourir la distance-(P) séparant deux coquilles (D). This set of chains (B) supporting the shells (D) is pushed forward by a jack (E) whose end carries a pawl (F) which bears on the bottom of the shell (D) makes it go through the distance - (P) separating two shells (D).
Le poste de travail (1) est destiné à la dépose manuelle de la carcasse (K) dans la coquille (D) par l'ouvrier mouleur venant de cnfectionner à la presse à compression la dite carcasse (K). The workstation (1) is intended for the manual removal of the carcass (K) in the shell (D) by the workman moulder just to change the compression press said carcass (K).
Le poste de travail (2) comprend un vérin (G) qui pousse un porte-outil (H) à travers deux coulisseaux de guidage (I) permettant à l'outil (J) d'atteindre le fond de la carcasse < K) contenue dans la coquille (D) et, prenant appui sur la butee (L) découpe le voile à l'endroit où se positionnera le verre fumé sur le masque définitif. The workstation (2) comprises a jack (G) which pushes a tool holder (H) through two guide slides (I) allowing the tool (J) to reach the bottom of the carcass <K) contained in the shell (D) and, resting on the stop (L) cut the veil at the place where the smoked glass will be positioned on the final mask.
Les postes de travail 3 et 4 comprennent un vérin de blocage < N) qui pousse un poinçon d'immobilisation < o) à travers une tige (N) guidée par deux coulisseaux (I) immobilisant fermement la carcasse (K) dans la coquille (D) pendant les opérations de meulage. The workstations 3 and 4 include a locking cylinder <N) which pushes an immobilization punch <o) through a rod (N) guided by two slides (I) firmly immobilizing the carcass (K) in the shell ( D) during grinding operations.
Le meulage-ébarbage est assuré par un rouleau (R) portant des bagues abrasives. Ce rouleau. < R) est actionné par un moteur électrique situé dans le chariot (Q) poussé par le vérin (P). The grinding-deburring is provided by a roller (R) carrying abrasive rings. This roll. <R) is actuated by an electric motor located in the carriage (Q) pushed by the jack (P).
Au poste (3) ce vérin travaille de la position (S1) à la position (S2) pour ébavurer la partie horizontale de la carcasse (K). At the station (3) this cylinder works from the position (S1) to the position (S2) to deburr the horizontal portion of the carcass (K).
Au poste 4 un ensemble identique passe de la position (U1) à la position (U2) pour assurer l'ébavurage de la partie inclinée du masque. At station 4 an identical set goes from position (U1) to position (U2) to deburr the inclined portion of the mask.
Au poste 5 un distributeur (U) vient déposer la contre-plaque (w) destinée à immobiliser le verre fumé. At station 5 a distributor (U) comes to deposit the counter plate (w) for immobilizing the smoked glass.
Au poste 6 deux visseuses (Y) déposent et vissent les deux écrous (Z) immobilisant les contre-plaques (W). At station 6 two screwdrivers (Y) deposit and screw the two nuts (Z) immobilizing the backplates (W).
Sur le brin de retour, la carcasse (K) après usinage étant devenue un produit fini chute par gravité sur un système évacuateur
SE.On the return strand, the carcass (K) after machining having become a finished product falls by gravity on an evacuator system
SE.
Fonctionnement : L'opérateur venant de mouler la carcasse (K) la dépose dans la coquille libre-du poste 1. Operation: The operator who has just molded the carcass (K) deposits it in the free shell of station 1.
Le vérin (E) pousse l'ensemble de la chaîne et la carcasse déposée passe au poste 2. The cylinder (E) pushes the whole chain and the carcass deposited passes to station 2.
Simultanément : - le vérin (G) poinçonne le voile de la lumière, - les vérins (M) descendent les poinçons 0. Simultaneously: - the jack (G) punch the veil of the light, - the cylinders (M) descend the punches 0.
Après un léger arrêt - le vérin (E) revient, - le vérin (P) va de Sl en 32, - le vérin (T) va de U1 en U2, - le distributeur (U) dépose la contre-plaque (W), - les visseuses (Y) vissent les écrous (Z). After a slight stop - the cylinder (E) returns, - the cylinder (P) goes from Sl to 32, - the cylinder (T) goes from U1 to U2, - the distributor (U) deposits the plate (W) - the screwdrivers (Y) screw the nuts (Z).
Après un léger arrêt - le vérin (P) revient de S2 EN S1, - le vérin (T) revient de U2 en Ul, - le distributeur (U) remonte en position repos, - les visseuses (Y) remontent en position repos. After a slight stop - the cylinder (P) returns from S2 EN S1, - the cylinder (T) returns from U2 in Ul, - the distributor (U) back to the rest position, - the screwdrivers (Y) back to the rest position.
Après un léger arrêt - les vérins (G) et (M) remontent ... le cycle est ainsi complet. After a slight stop - the cylinders (G) and (M) go up again ... the cycle is thus complete.
