  PROCEDE ET INSTALLATION POUR FABRIQUER DES FONDS DE TUBES EN MATIERE

PLASTIQUE.

  
Il existe plusieurs procédés pour la fabrication de.fonds de tubes en matière plastique. Un procédé consiste à partir de flans de matière première en feuilles pour obtenir les tubes et à rapporter les

  
fonds emboutis, injectés ou découpés par soudure. Un autre procédé consiste à obtenir les récipients proprement dits par emboutissage, mais ce procédé n'est applicable que pour des tubes dont la hauteur est de l'ordre de grandeur du diamètre; par injection on peut obtenir une profondeur beaucoup plus importante mais pour chaque dimension le tube doit correspondre un moule très onéreux. Un autre procédé consiste à utiliser la matière du bord du tube pour former le fond par plissage et rabattement de ce bord sur lui-même et fusion par courants haute fréquence.

  
La présente invention a pour objet les perfectionnements à ce dernier procédé et un appareil pour la fabrication en série de fonds de tubes.

  
Ce procédé est caractérisé par les opérations successives suivantes :

  
On part de matière plastique granulée, telle. que chlorure de polyvinyle et on la transforme en tube par un procédé usuel, boudinage

  
ou autres, puis on coupe ce boudin en tubes élémentaires à la longueur voulue.

  
On pose le tube sur un mandrin de forme quelconque avec emploi d'une bague de positionnement; on préforme l'extrémité de ce tube par plissage dyun de ses bords dans une bouterolle en forme de calotte chauffée à 60-80[deg.], on coiffe éventuellement le mandrin sur lequel sont déjà rabattues par ce préformage les parties plissées du tube sous une seconde bouterolle plate qui écrase le plissage déjà formé et on le fixe en dimen-sions avec refroidissement; puis on traite le fond des tubes ainsi formés par thermie ou haute fréquence.

  
Dans le cas de tubes de grand diamètre, on ajoute dans le tube une pastille de matière thermoplastique destinée à complèter la matière du bord du tube pour la formation du fond par le chauffage subséquent à haute fréquence.

  
Le dispositif pour réalises ce procédé, peut comporter un

  
 <EMI ID=1.1> 

  
métal conducteur mis à la masse constituant les mandrins sur lesquels sont engagés les tubes de matière plastique coupés aux dimensions voulues; ces broches sont successivement amenées sous des postes fixes de préformage et de traitement à la haute fréquence, et éventuellement les postes d'addition de pastilles ou d'aplatissement à froid du fond préformé.

  
Les électrodes de chauffage à haute fréquence comportent une plaque métallique avec dispositif de verrouillage de leur support, un man-

  
 <EMI ID=2.1> 

  
métal-acétate interposé entre les broches et l'électrode.

  
On décrira plus en-détail ci-après le procédé de fabrication des fonds de tubes en matière plastique suivant l'invention en référence au dessin annexé sur lequel :
La figure 1 montre en coupe verticale un morceau de tube en plastique. <EMI ID=3.1>  preinte de préformage vue en coupe. La figure 3 montre ce tube après plissage d'une de ses parois terminales. La figure 4 montre ce tube après plissage sous une bouterolle d'égalisation. La figure 5 montre ce tube sous l'électrode de chauffage à haute fréquence.

  
Les figures 6, 7, 8, 9 montrent le procédé appliqué à des tubes de plus grand diamètre avec addition de matière.

  
La figure 10 est une vue d'une électrode de chauffage à haute <EMI ID=4.1>  La figure 11 est une vue schématique d'une machine de fabrication continue. La figure 12 est une vue d'une variante de l'appareil.

  
Le procédé suivant l'invention peut être expliqué en référence

  
aux figures 1 à 6 du dessin annexé : le tube élémentaire 7, coupé à une longueur un peu supérieure à celle du tube définitif dans un boudin tubulaire de matière plastique appropriée (figure 1), est mis en place sur une broche 2 qu'il dépasse légèrement d'une quantité 9 réglée par la position de la butée réglable constituée par la bague 8 et amenée sous la bouterolle-15 (figure 2); celle-ci est creusée en cuvette en forme de calotte 22 et chauffée à une température ramollissant les parois terminales du tube à son contact sans détériorer la matière 50-80[deg.]G de sorte qu'en appliquant l'empreinte sur le tube (figure 3), les parois terminales 24 sont plissées et rabattues les unes sur les autres.

  
. Le fond ainsi formé est éventuellement passé ensuite sous une deuxième bouterolle 23 (figure 4) qui est à fond plat 28 et qui refroidit et stabilise le préforme qui vient d'être obtenu.

  
Le tube ainsi formé est .ensuite amené sous l'électrode à haute fréquence 26 qui égalise par chauffage à pertes diélectriques le fond 24 pour le rendre lisse et uni (figure 5).

  
Les bouterolles 15 et 23 de l'électrode 26 peuvent avoir des formes très variées suivant la fabrication envisagée.

  
La soudure se fait immédiatement après préformage quand la partie formée du tube ainsi que la partie supérieure du mandrin ont encore une température de 18[deg.] à 20[deg.] pour une électrode de forme et de condition appropriées à la forme du fond.

  
S'il s'agit de tubes de diamètre important où l'on aurait des difficultés à souder avec égalité tout le fond du tube, on remplace la bouterolle 15 de la figure 2 par un poinçon 29 de découpe d'une pastille
30 d'une bande 31 de matière plastique (figure 6) placée au-dessus d'une matrice de découpe 32 - la pastille 30 est poussée par le poinçon 29 dans la partie du tube 7 dépassant le mandrin 2 (figure 7). Les bouterolles
23 de la figure 4 et électrode 26 de la figure 5 sont modifiées comme le montre les figures 8 et 9 pour sertir le bord du tube 7 sur la pastille
30.

  
L'électrode 26 coiffe de toute façon la partie préformée, et effectue sous pression la soudure haute fréquence.

  
Cette électrode 26 peut être réalisée comme montré figure 10 ;

  
La partie supérieure 18 représente la partie électrode proprement dite. 

  
Une bague 19 en produit isolant assure un encerclement calibré de la partie supérieure du tube. 

  
Un support 21 maintient cette bague 19.

Un élément de verrouillage 25 peut assembler le tout.

  
Un condensateur 27 est placé entre l'électrode et la partie

  
à souder .

  
Ce condensateur est composé d'une épaisseur appropriée de matière thermoplastique, par exemple d'acétate de cellulose ou de triacétate, et d'une feuille préférablement en métal autre que celui utilisé pour l'électrode.

  
L'électrode étant en duralumin, la feuille de métal sera laiton ou cuivre ou vice-versa.

  
L'avantage de cette électrode munie de condensateur est d'accélérer (pour une puissance égale) très considérablement la soudure. L'abaissement du temps de soudure est de 3 à 1 seconde.

  
On peut prévoir différentes machines pour amener en continu les broches porte-tubes sous les postes de préformage et de finition ou pour déplacer ces postes devant les broches. Les commandes nécessaires

  
à l'obtention de ces opérations peuvent être obtenues, soit mécaniquement, soit par air comprimé, soit par un dispositif électromagnétique ou hydraulique.

  
A titre indicatif et pour illustrer le procédé on décrira ciaprès un exemple de réalisation mécanique en référence à la figure 11 du dessin annexé.

  
Sur un plateau rotatif 1 sont disposés plusieurs groupes de broches 2 préférablement amovibles, en métal conducteur et reliés à la masse.

  
Au-dessus de ce plateau sont placés en des points de sa périphérie des postes de préformage et un poste de finition à haute fréquence.

  
Le premier poste comprend un boîtier porte-empreintes de matriçage 5 susceptible d'être abaissé sur les broches, les bouterolles 15 portées par ce boîtier sont chauffées électriquement par une résistance
16 et présentant un profil en forme de cuvette favorisant le repli des bords du tube.

  
Eventuellement on peut prévoir un deuxième poste comprenant une bouterolle à fond plat susceptible de s'abattre sur le fond plissé pour l'égaliser à froid.

  
Le troisième poste comprend une tête 6 d'appareil haute fréquence en contact avec des électrodes 26 amovibles et de profil variables; ce poste est aussi susceptible d'être abaissé pour venir former le fond du tube.

  
Dans le cas de moyens thermiques autres que la haute fréquence, les électrodes isolantes sont reliées à une source de chaleur suffissamment importante pour amener la partie 24 à l'état de ramollissement nécessaire pour que sous l'effet d'une pression la soudure se réalise.

  
Les postes sont solidaires d'un manchon 14 monté coulissant sur l'extrémité supérieure de l'axe 13 du plateau et maintenu en position haute par un ressort 12.

  
Une pédale 11 reliée par un brin souple 10 au manchon 14 commande l'abaissement des postes de préformage 3. Les bouterolles 15 portées par résistance 16 à une température appropriée à la matière replient rapidement les bords ramollis 9 des tubes et les plissent les uns sur les autres. L'action sur la pédale 11 se continuant,les électrodes 26

  
 <EMI ID=5.1> 

  
mé 24; sous l'action de la haute fréquence ou de la chaleur communiquée

  
à 18 les fonds plissés fondent instantanément et les tubes sont terminés. On cesse l'action sur la pédale 11, les postes 3 et 4 remontent, on imprime au plateau 1 un mouvement rotatif d'un quart de tour, on retire les tubes terminés et approvisionne en tubes à préformer et le cycle recommence. Il est à noter que le poste 3 est monté coulissant sur le manchon 14 et soumis à l'action d'un ressort antagoniste 17 afin de permettre l'abaissement du poste 4, tout en restant lui-même en contact avec les tubes.

  
Au lieu de plateau à déplacement linéaire ou rotatif et de postes de préformage et de finition fixes on pourrait prévoir l'inverse. Les commandes des porte-empreintes et porte-électrodes pourraient naturellement varier, de même que la constitution du porte-électrodes et des dispositifs de détail ci-dessus décrits.

  
Une variante de l'appareil de la figure 11 est représentée à la figure_12.

  
 <EMI ID=6.1> 

  
ches 2.

  
Les postes A sont des postes où s'effectue la pose par l'ouvrier de deux tubes 7 sur chaque couple de broches.

  
Le poste B comporte les bouterolles de préformage 15 de la figure 2 ou les poinçons de découpe 29 de la figure 6.

  
Le poste C comporte les bouterolles d'aplatissement 23 de la figure 4 ou de sertissage de la figure 8.

  
 <EMI ID=7.1> 

  
dans tous les cas et le poste E est le poste d'éjection.

  
Ce plateau tourne à volonté de l'ouvrier par saccades successives, avec un rendement considérablement accru par rapport à celui des procédés connus, du fait de la rapidité de la soudure.

  
Les tubes:ainsi obtenus rapidement, avec une main d'oeuvre réduite et dans un temps très court sont d'une belle finition; il y a une solution de continuité entre les parois et le fond, aucun risque de fuite, bien qu'il n'y ait eu aucun apport de matière. Ils peuvent'être à fond plat ou à fond en forme-d'embout distributeur.
