System for thermally treating workpieces with an explosive gas mixture, in particular, a thermal deburring system

Abstract

A system for the thermal treatment of work pieces with an explosive gas mixture, in particular, a thermal deburring system, has a processing chamber (10), which includes a combustion chamber (12) for receiving the work pieces. A supply channel (18) for the gas mixture opens into the combustion chamber (12). In the combustion chamber (12), a device is provided, which has a plurality of openings through which the flame front passes for thermally treating the work pieces. The device can be one that connects to the supply channel (18), preferably in the form of a tube (26) with a plurality of openings (28), which can be made from an extruded sheet. The work pieces obtain a more uniform processing or deburring effect, since the flame front passes through the many small openings of the device. The small openings (28) serve also as throttles, whereby the entire combustion process runs for a longer time.
