Oscillating hot press sintering furnace

Abstract

The invention provides an oscillating hot press sintering furnace and relates to the field of high-performance ceramic and powder metallurgy material preparation, in particular to equipment adopting the hot press sintering method. The oscillating hot press sintering furnace comprises a furnace body and a hydraulic mechanism. An upper water cooling pressure head, an upper graphite pressure head, a lower water cooling pressure head and a lower graphite pressure head are arranged inside the furnace body. The hydraulic mechanism comprises an upper oil press and a lower oil press. The upper oil press is connected with the upper water cooling pressure head. The lower oil press is connected with the lower water cooling pressure head. The top of the upper water cooling pressure head and the bottom of the lower water cooling pressure head are provided with electromagnetic resonance pressure applying devices correspondingly. The electromagnetic resonance pressure applying devices can adjust the vibration frequency, vibration amplitude and pressure while hot press sintering is conducted. According to the oscillating hot press sintering furnace provided by the invention, high-frequency vibration amplitude/pressure can be achieved through the bidirectional pressurizing mode, the sintering time is shortened, energy consumption is reduced, and the compactness of a product is more uniform; and in addition, system faults can be found in time, and safe production is guaranteed.
