Abstract

Ein Pressstempel zum Herstellen keramischer Fliesenrohlinge umfaßt eine Stempelträgerplatte (2), eine auf der Stempelträgerplatte (2) angeordnete Stempelgrundplatte (3) und eine Stempeldeckplatte (4). Die einander gegenüber liegenden Oberflächen der Stempelgrundplatte (3) und der Stempeldeckplatte (4) sind eben. Zwischen diesen ebenen Oberflächen sind Drucksensoren (6) mit planparallelen Oberflächen und einem bei Druckeinwirkung seine elektrischen Eigenschaften ändernden Messfühlersystem angeordnet. Die Dicke der Stempeldeckplatte (4) wird in Abhängigkeit von dem spezifischen Pressdruck und der Empfindlichkeit der Drucksensoren (6) gewählt. Die Drucksensoren (6) messen die durch die Stempeldeckplatte (4) auf die Stempelgrundplatte (3) übertragenen Druck-Reaktionskräfte. Die von den Drucksensoren gelieferten elektrischen Signale dienen für die Steuerung des Produktionsprozesses.

A pressing die for producing ceramic tile blanks comprises a punch carrier plate (2), a punch base plate (3) arranged on the punch carrier plate (2) and a punch cover plate (4). The opposing surfaces of the stamp base plate (3) and the stamp cover plate (4) are flat. Between these flat surfaces, pressure sensors (6) with plane-parallel surfaces and a sensor system changing its electrical properties when pressure is applied are arranged. The thickness of the stamp cover plate (4) is selected depending on the specific pressing pressure and the sensitivity of the pressure sensors (6). The pressure sensors (6) measure the pressure reaction forces transmitted through the die top plate (4) to the die base plate (3). The electrical signals supplied by the pressure sensors are used to control the production process.
