Abstract
Description
Zum Thermoformen von thermoplastischen Folien und Platten sind für den Labor-, und Testbetrieb einfache, von Hand betätigte Geräte bekannt. Sie eignen sich zur einfachen Demonstration des Positiv-Formverfahrens. Negativformung, insbesondere mit Oberstempel, ist wegen der fehlenden Betätigungseinrichtung für den Oberstempel und der fehlenden Einbaumöglichkeit von Negativformen nicht möglich. Ein bekanntes Gerät ermöglicht durch den Kurvenantrieb für den Formtisch das Einschalten des Vakuums über den Tischhebel indem in der oberen Tischendlage ein Rastpunkt überfahren wird. Während dieser Weiterbewegung wird das Vakuumventil betätigt. Der Nachteil hierbei ist das ungewollte Überfahren des Rastpunktes und Einschalten des Vakuums zum falschen Zeitpunkt. Pneumatisch betätigte Oberstempeleinrichtungen sind bekannt. Sie sind bei handbetätigten Geräten aus Sicherheitsgründen jedoch nicht erwünscht. Auf Seite 4 sind die üblichen Formverfahren schematisch dargestellt. Die bekannten Geräte ermöglichen nur die Verfahren nach Ziffer 1–3. Die produktionsmäßig angewendeten Formverfahren sind deshalb nur eingeschränkt durchführbar. Für die Durchführung von Testformungen zur Bemusterung von neu entwickelten Formteilen, sowie in der Ausbildung, sollte die in der Produktion angewendeten Formverfahren möglich sein.To the Thermoforming of thermoplastic films and sheets are for laboratory, and test operation known simple, hand-operated devices. They are suitable for a simple demonstration of the positive molding process. Negative shaping, especially with upper stamp, is due to the lack of an actuator for the Upper stamp and the lack of installation options for negative forms not possible. A well-known device allows through the cam drive for the forming table by switching on the vacuum using the table lever in a rest point is passed over the upper table end position. During this The vacuum valve is actuated for further movement. The disadvantage here is the unwanted running over the rest point and switching on the vacuum at the wrong time. Pneumatically operated upper stamp devices are known. However, they are for hand-operated devices for safety reasons not wanted. On page 4 are the usual molding processes shown schematically. The known devices only allow the process according to Numbers 1-3. The used in production Molding processes can therefore only be carried out to a limited extent. For the implementation of Test moldings for sampling newly developed molded parts, as well in training, the molding process used in production possible his.
Das nachfolgend beschriebene und in den Zeichnungen dargestellte Gerät soll die vorgenannten Nachteile beseitigen und zur Möglichkeit der Negativformung mit Oberstempel die folgende Einrichtungen in Kombination enthalten. Eine handbetätigte Oberstempeleinrichtung, Formtisch-Bewegungseinrichtung für Einbaumöglichkeit von Negativformen, Vakuumschaltung über den Formtisch-Betätigungshebel mit freier Wahl des Schaltpunktes.The The device described below and shown in the drawings is said to Eliminate the aforementioned disadvantages and the possibility of negative molding with upper stamp containing the following facilities in combination. A manually operated upper stamp device, Form table moving device for installation option negative molds, vacuum switching via the mold table operating lever with free choice of switching point.
