Abstract
Description
L'invention se rapporte à un châssis chauffant résistant à la compression, comprenant plus particulièrement une plaque supérieure et une plaque inférieure fixées l'une à l'autre.The invention relates to a heating frame resistant to compression, more particularly comprising an upper plate and a lower plate fixed to one another.
Un châssis chauffant comprenant une plaque supérieure et une plaque inférieure fixées l'une à l'autre est connu du document CH 328013 publié le 15 avril 1958. Le châssis comprend un moyen de chauffage électrique disposé entre les deux plaques ainsi que des barrettes en bois ou en matière plastique disposées de part et d'autre du moyen de chauffage et intercalées entre la plaque supérieure et la plaque inférieure. La résistance à la compression de ce châssis est principalement assurée par le moyen de fixation des deux plaques l'une à l'autre. Les barrettes de bois ou de matière plastique renforcent cette résistance mais en transmettant intégralement les efforts de compression au moyen de chauffage entre lesquelles il est intercalé.A heating frame comprising an upper plate and a lower plate fixed to each other is known from document CH 328013 published April 15, 1958. The frame comprises an electric heating means disposed between the two plates as well as wooden bars. or plastic disposed on either side of the heating means and interposed between the upper plate and the lower plate. The compressive strength of this frame is mainly ensured by the means of fixing the two plates to one another. The bars of wood or plastic reinforce this resistance but by transmitting the compression forces integrally by means of heating between which it is interposed.
Un châssis chauffant offrant une meilleure résistance à la compression est connu du document EP-A-2 639 005 publié le 15 novembre 1988. Selon ce document, la plaque inférieure du châssis comprend des logements pour recevoir le moyen de chauffage constitué en l'occurrence de résistances électriques. Les logements sont séparés les uns des autres par des surépaisseurs de la plaque inférieure de sorte que les résistances électriques sont protégées de tout écrasement lorsque le châssis est soumis à un effort comprimant les plaques inférieure et supérieure l'une contre l'autre. Un châssis d'un type analogue est encore connu du document FR 822661 publié le 4 juin 1937. Les éléments chauffants sont disposés entre les plaques inférieure et supérieure du châssis et protégés contre un écrasement par des feuillards maintenant un espace entre les deux plaques dans lequel des résistances électriques sont disposées.A heating frame with improved compressive strength is known from EP-A-2 639 005 published November 15, 1988. According to this document, the bottom plate of the frame comprises housings for receiving the heating means constituted in this case of electric resistances. The housings are separated from each other by lower thicknesses of the lower plate so that the electrical resistances are protected from crushing when the frame is subjected to a force compressing the lower and upper plates against each other. A frame of a similar type is still known from FR 822661 published June 4, 1937. The heating elements are arranged between the lower and upper plates of the frame and protected against crushing by strips maintaining a space between the two plates in which electrical resistances are arranged.
Les deux derniers châssis qui viennent d'être décrits, tout en protégeant efficacement le moyen de chauffage lors d'une compression, présentent toutefois l'inconvénient d'une mauvaise homogénéité de chauffage par rapport à l'étendue de la plaque inférieure ou de la plaque supérieure. En effet, l'alternance des résistances électriques et des moyens mécaniques, surépaisseurs ou feuillards, protégeant ces résistances électriques contre un écrasement crée une variation périodique de la température des plaques inférieure et supérieure du châssis. La température est plus élevée à l'endroit d'une résistance électrique et plus faible à l'endroit du moyen mécanique de protection contre l'écrasement.The last two frames that have just been described, while effectively protecting the heating means during compression, however, have the disadvantage of a poor heating homogeneity with respect to the extent of the lower plate or the top plate. Indeed, the alternation of electrical resistances and mechanical means, oversizes or strips, protecting these electrical resistances against crushing creates a periodic variation in the temperature of the lower and upper plates of the frame. The temperature is higher raised at the location of an electrical resistance and lower at the location of the mechanical means of protection against crushing.
Le but de l'invention est ainsi de modifier ces châssis existants pour leur conférer une plus grande homogénéité de chauffage tout en leur conservant une résistance élevée à la compression.The object of the invention is thus to modify these existing frames to give them a greater homogeneity of heating while maintaining a high resistance to compression.
A cet effet, l'invention a pour objet un châssis chauffant résistant à la compression, selon la revendication 1.For this purpose, the subject of the invention is a heating frame which is resistant to compression, according to claim 1.
Les plots de reprise d'effort confèrent au châssis selon l'invention une grande résistance mécanique à la compression tout en permettant une grande homogénéité thermique de chaque plaque. Le moyen de chauffage est protégé contre un écrasement par sa disposition dans un espace créé entre les deux plaques par les plots de reprise d'effort.The stress recovery pads give the frame according to the invention a high mechanical resistance to compression while allowing a high thermal homogeneity of each plate. The heating means is protected against crushing by its arrangement in a space created between the two plates by the force recovery studs.
Selon un premier mode d'exécution de l'invention, les plots de reprise d'effort sont répartis aux noeuds d'un réseau géométrique carré centré. Selon une deuxième mode d'exécution de l'invention, les plots sont répartis aux noeuds d'un réseau géométrique hexagonal. Selon un troisième mode d'exécution de l'invention, les plots de reprise d'effort sont répartis aux noeuds d'un réseau géométrique carré.According to a first embodiment of the invention, the stress recovery studs are distributed at the nodes of a centered square geometric network. According to a second embodiment of the invention, the pads are distributed at the nodes of a hexagonal geometric network. According to a third embodiment of the invention, the stress recovery studs are distributed at the nodes of a square geometric network.
Le chauffage du châssis, assuré par le film disposé dans l'espace créé entre les plaques inférieure et supérieure par les plots de reprise d'effort, permet de réduire considérablement l'épaisseur totale du châssis. Le film chauffant est par exemple constitué d'une feuille en matière plastique, en céramique ou encore en mica d'une épaisseur typique de 1 mm. Un circuit conducteur est imprimé sur l'une des faces du film de façon à produire par effet joule un échauffement qui peut engendrer une température de chauffage comprise entre 150 et 200° et fournir une puissance calorifique d'environ 10 watt par cm2.The heating of the frame, ensured by the film arranged in the space created between the lower and upper plates by the force recovery studs, significantly reduces the total thickness of the frame. The heating film is for example made of a plastic sheet, ceramic or even mica of a typical thickness of 1 mm. A conductive circuit is printed on one of the faces of the film so as to produce a heating effect by joule that can generate a heating temperature of between 150 and 200 ° and provide a heating power of about 10 watts per cm 2.
Le document US 3 181 605 divulgue un châssis conforme au préambule de la revendication 1, dans lequel le moyen de chauffage est un fluide caloporteur circulant à l'intérieur d'un labyrinthe suivant deux sens de circulation opposés. Le labyrinthe comprend des éléments de séparation intercalés entre les deux plaques.US 3 181 605 discloses a frame according to the preamble of claim 1, wherein the heating means is a heat transfer fluid circulating inside a labyrinth following two opposite flow directions. The labyrinth comprises separating elements interposed between the two plates.
Le document GB 890 940 divulgue là encore un châssis conforme au préambule de la revendication 1, dans lequel moyen de chauffage est constitué d'une part de bobines électriques enroulées localement autour des plots de reprise d'effort, et d'autre part de canaux pour la circulation d'un fluide caloporteur.GB 890 940 discloses again a frame according to the preamble of claim 1, wherein the heating means is constituted on the one hand of electric coils wound locally around the stress recovery pads, and on the other hand of channels for the circulation of a coolant.
Le document US 1 884 612 divulgue un châssis comprenant une plaque unique percée suivant deux directions perpendiculaires de canaux de circulation d'un fluide caloporteur.Document US 1,884,612 discloses a frame comprising a single plate pierced along two perpendicular directions of circulation channels of a heat transfer fluid.
Le document DE 203 04 974 divulgue un châssis dans lequel le moyen de chauffage, non précisé, est intégré à l'une des deux plaques. Une couche d'isolation thermique est intercalée entre les deux plaques, séparées l'une de l'autre par les plots de reprise d'effort.DE 203 04 974 discloses a frame in which the heating means, unspecified, is integrated with one of the two plates. A thermal insulation layer is interposed between the two plates, separated from each other by the force recovery studs.

Un châssis chauffant résistant à la compression comprend, figure 1, une plaque supérieure 1 et une plaque inférieure 3 fixées l'une à l'autre par un moyen de fixation non représenté qui est par exemple un ensemble de vis traversant la plaque supérieure et venant se visser dans un filetage de la plaque inférieure. La plaque supérieure 1 est par exemple une plaque d'isolation thermique et la plaque inférieure présente par exemple une structure en nid d'abeille.A compression-resistant heating frame comprises, FIG. 1, an upper plate 1 and a
Dans cette application particulière, le châssis est destiné à être installé dans le sommier d'une presse utilisée pour la dorure à chaud d'éléments en plaque. La dorure est déposée par estampage à chaud d'une bande métallisée sur une feuille par exemple de carton, destinée à la réalisation d'un emballage. Des clichés 4 sont fixés sur la plaque inférieure 3 et chauffés par le châssis pour atteindre une température typiquement comprise entre 100° et 200°C.In this particular application, the frame is intended to be installed in the bed base of a press used for the hot stamping of plate elements. The gilding is deposited by hot stamping a metallized strip on a sheet, for example of cardboard, for the realization of a package.
L'élévation et le maintien en température du châssis est assuré par un moyen de chauffage 5 intercalé entre les plaques supérieure 1 et inférieure 3.The elevation and temperature maintenance of the frame is provided by a heating means 5 interposed between the upper and
Selon l'invention, des plots de reprise d'effort 71,72 sont disposés entre les deux plaques 1 et 3 pour résister à des efforts de compression des plaques l'une contre l'autre et sont répartis de façon telle à permettre un chauffage homogène de chaque plaque. Comme illustré par la figure 1, le moyen de chauffage 5 est intercalé entre les deux plaques 1 et 3 du châssis en étant disposé dans un espace créé entre ces deux plaques par les plots de reprise d'effort 71,72. Les plots de reprise d'effort 71,72 protègent ainsi le moyen de chauffage 5 d'un écrasement lorsque le châssis est soumis à un effort de compression tout en diminuant l'encombrement de ce moyen de protection par rapport à l'étendue des plaques du châssis. D'où il résulte une meilleure couverture des plaques par le moyen de chauffage conduisant à une meilleure homogénéité thermique du châssis.According to the invention,
Les plots de reprise d'effort 71,72 sont de préférence répartis au noeud d'un réseau géométrique. Comme cela est illustré par la figure 2, les plots de reprise d'effort 71,72 sont répartis au noeud d'un réseau 91 carré centré. D'autres réseaux géométriques sont également prévus, comme par exemple un réseau hexagonal ou un réseau carré.The
Avec un réseau rectangulaire centré, les plots de reprise d'effort sont distribués aux quatre coins d'un motif élémentaire rectangulaire, un cinquième plot étant disposé au centre du rectangle. Dans un réseau hexagonal, les plots sont disposés à l'intersection deux à deux des six côtés d'un hexagone. Enfin dans un réseau géométrique carré, les plots de reprise d'effort sont disposés aux quatre coins du carré.With a rectangular network centered, the stress recovery studs are distributed at the four corners of a rectangular elementary pattern, a fifth stud being disposed in the center of the rectangle. In a hexagonal network, the studs are arranged at the intersection in pairs of six sides of a hexagon. Finally, in a square geometric network, the stress recovery studs are arranged at the four corners of the square.
A titre d'exemple, une répartition selon le réseau carré centré 91 illustré par la figure 2 permet d'homogénéiser la température de la plaque inférieure 3 du châssis illustré par la figure 1, à une valeur de 160°C pour une diminution locale de la température à l'endroit des plots de reprise d'effort 7 inférieure à 1°C lorsque la plaque est laissée à l'air libre.By way of example, a distribution according to the square
Comme illustré par les figures 1 et 3, les plots de reprise d'effort 71,72 sont pourvus d'une collerette 11 pour répartir les efforts de compression sur une tôle de fond 13 intercalée entre la plaque supérieure 1 et le moyen de chauffage 5. Cet agencement permet avantageusement de diminuer la pression exercée par les plots de reprise d'effort 71,72 sur la plaque supérieure 1. D'où la possibilité de choisir un matériau moins fortement résistant à la compression pour réaliser la plaque supérieure 1 sous la forme d'une plaque d'isolation thermique, comme une résine époxy chargée avec des fibres de verre.As illustrated by FIGS. 1 and 3, the load-bearing
La collerette 11 des plots de reprise d'effort 71,72 peut prendre appui directement sur la plaque inférieure 3 ou sur une tôle de fermeture 15 intercalée entre le moyen de chauffage 5 et la plaque inférieure 3. La plaque de fermeture 15 est choisie de façon à diffuser rapidement la chaleur sur toute l'étendue de la plaque inférieure 3 pour contribuer à la bonne homogénéité thermique du châssis.The
Il convient de noter que les plots de reprise d'effort 71,72 pourvus des collerettes 11 peuvent s'étendre à travers la plaque inférieure 3 - plots référencés 71 - ou ne s'étendre qu'entre la plaque supérieure 1 et la tôle de fermeture 15 - plots référencés 72. Ces deux types de plots de reprise d'effort sont plus particulièrement illustrés respectivement par les figures 3a et 3b.It should be noted that the
Un matériau d'isolation thermique, par exemple un feutre céramique 17, est intercalé entre le moyen de chauffage 5 et la plaque supérieure 1 pour d'une part limiter l'échauffement thermique de la plaque supérieure 1 et d'autre part comprimer le moyen de chauffage 5 pour garantir un bon contact thermique entre ce moyen de chauffage et la tôle de fermeture 15 ou la plaque inférieure 3.A thermal insulation material, for example a
Comme indiqué précédemment, le moyen de chauffage est de préférence un film disposé entre les plaques inférieure 3 et supérieure 1 et percé de trous pour permettre le passage des plots de reprise d'effort 71,72. Cet agencement permet de réduire considérablement l'épaisseur totale du châssis. Une telle réduction d'encombrement permet de transformer des presses utilisées initialement à des fins de découpage en presses pour effectuer des opérations de transfert de bandes métallisées à chaud.As indicated above, the heating means is preferably a film disposed between the
