Description

Preßplatten, auch Heiz- und Kühlmäntel mit Heizkanälen für Pressen. Bei bekannten Anordnungen der Heizkanäle in Preßplatten, auch Heiz- und -Kühlmänteln von Pressen sind die Kanäle durch senkrecht oder schräg zu ihnen verlaufende Bohrungen miteinander verbunden. Erstere bedingen einen ziemlich scharfen Richtungswechsel, auch lassen sie sich infolge ihrer Länge schwer reinigen. Letztere ermöglichen zwar ein bequemeres Durchstoßen, aber sie bedingen am einen Ende einen scharfen, spitzwinkligen Richtungswechsel, wodurch der Durchströmungswiderstand erheblich vergrößert wird und bei Dampfheizung hohe Kondensationsverluste verursacht werden.Press plates, also heating and cooling jackets with heating channels for presses. In known arrangements of the heating channels in press plates, including heating and cooling jackets of presses are the channels through bores running perpendicular or diagonally to them connected with each other. The former require a fairly sharp change of direction, they are also difficult to clean because of their length. The latter make it possible a more comfortable piercing, but they require a sharp, acute-angled one at one end Change of direction, which significantly increases the flow resistance and high condensation losses are caused by steam heating.

Gegenstand der Erfindung sind nun Preßplatten, Heiz- und Kühlmäntel mit Heizkanälen, bei denen die Verbindungskanäle infolge ihrer Kürze sich leicht reinigen lassen und durch ihre Anordnung nur stumpfwinklige Richtungsänderungen ergeben. Außerdem reichen,die Verschlüsse der Kanäle bis zu den Einmündungen der Verbindungsbohrungen, so daß tote Winkel und Ecken, die Ablagerungen begünstigen, gleichfalls nicht vorhanden sind.The invention now relates to press plates, heating and cooling jackets with heating ducts, in which the connecting ducts are easy due to their shortness can be cleaned and due to their arrangement only obtuse changes of direction result. In addition, the closures of the channels up to the junctions of the Connecting holes so that dead angles and corners that favor deposits, are also not present.

Auf der Zeichnung ist eine Ausführungsform einer solchen Heizkanalanordnung dargestellt.The drawing shows an embodiment of such a heating channel arrangement shown.

D,ie Heizkanäle i in der Platte 2 laufen parallel oder ungefähr parallel zu den kurzen Plattenkanten, so daß sie die geringste mögliche Länge haben. Je zwei benachbarte Kanäle sind an ihren Enden abwechselnd auf der einen und der anderen Seite miteinander durch zwei kurze schräge Bohrungen 3 verbunden, die in eine Kammer 4. münden. Auf diese Weise wird ein schlangenförmiger Leitungsweg gehiadet. Die Znden der Kanäle i sind zwischen .den Plattenkanten und der Einmündung der Bohrungen 3 durch herausnehmbare Stopfen 5 verschlossen, ebenso sind die Kammern q durch Stopfen G nach außen hin abgesperrt. Die öffnung der Kammern ist so groß, daß der volle Querschnitt der Bohrungen 3 geradlinig befahrbar ist. Es können also säi.n.tkche Kanäle schnell und leicht durchstoßen und so gereinigt werden. Da die Kanäle leic'it zugänglich sind, lassen sich leicht Pvrometer, Thermometer o. dgl. einschieben. Die Bohrungen 3 können weiter sein als die Kanäle i, so daß die Durchströmungsquerschnitte an den Stellen der Richtungswechsel größer sind, wodurch die Widerstände noch mehr vermindert werden.The heating channels i in the plate 2 run parallel or approximately parallel to the short plate edges so that they have the shortest possible length. Two each adjacent channels are at their ends alternately on one and the other Side connected to one another by two short oblique holes 3 that lead into a chamber 4. open out. In this way, a serpentine conduction path is hatched. the The channels i are ignited between .den plate edges and the confluence the Bores 3 closed by removable stoppers 5, as are the chambers q blocked from the outside by plug G. The opening of the chambers is so large that the full cross section of the holes 3 can be driven in a straight line. So it can säi.n.tkche channels can be pierced quickly and easily and cleaned in this way. Since the Channels are easily accessible, can easily be Pvrometer, thermometer or the like. slide in. The bores 3 can be wider than the channels i, so that the flow cross-sections at the points of change of direction are greater, whereby the resistance is even greater be reduced.

PATENTANSPRÜCHE: i. Preßplatte, auch Heiz- oder Kühlmantel für Pressen, mit quer zur Platte oder in der Mantellinie verlaufenden Kanälen, deren Enden licht lösbar verschlossen und von denen immer je zwei benachbarte abwechselnd an der einen und der anderen Seite durch Verbindungskanäle aneinander angeschlossen sind, dadurch gekennzeichnet, daß diese Verbindungskanäle je aus zwei Bohrungen (3) bestehen, die in an sich bekannter Weise stumpf in die beiden benachbarten Querkanäle (i) einmünden und nach außen hin ,in einer ebenfalls leicht lösbar verschlossenen Kanliner (4) stumpf zusammenstoßen. z. Preßplatte, auch Heiz- oder Kühlinantel nach Anspruch z, dadurch gekennzeichnet, daß die Verschlüsse (5) der Querkanäle (i) bis zur Einmündung der Verbindungsbohrungen (3) in die Querkanäle reichen. PATENT CLAIMS: i. Press plate, also heating or cooling jacket for presses, with channels running transversely to the plate or in the surface line, the ends of which are closed releasably light and of which always two adjacent ones are alternately connected to one another on one and the other side by connecting channels, characterized in that, that these connecting channels each consist of two bores (3) which, in a known manner, open butt into the two adjacent transverse channels (i) and butt to the outside in a likewise easily detachable closed channel (4). z. Press plate, also heating or cooling jacket according to claim z, characterized in that the closures (5) of the transverse channels (i) extend as far as the confluence of the connecting bores (3) in the transverse channels.
