Three-section type vacuum sintering device

Abstract

The invention discloses a three-section type vacuum sintering device. The three-section type vacuum sintering device comprises a sintering chamber, a feeding chamber and a discharging chamber, whereinthe sintering chamber is provided with first sealing doors; the feeding chamber is provided with a second sealing door, a first carrying mechanism is arranged in the feeding chamber, and after the feeding chamber communicates with the sintering chamber through butt joint of the second sealing door and the corresponding first sealing door, the first carrying mechanism carries materials in the feeding chamber into the sintering chamber; the discharging chamber is provided with a third sealing door and a gas cooling mechanism, a second carrying mechanism is arranged in the discharging chamber, and after the discharging chamber communicates with the sintering chamber through butt joint of the third sealing door and the corresponding first sealing door, the second carrying mechanism carries the materials in the sintering chamber into the discharging chamber; and the feeding chamber and the discharging chamber are provided with vacuum exhausting mechanisms respectively. The three-section type vacuum sintering device realizes ordered segmentation of three working procedures of pre-vacuumizing, vacuum heating and gas cooling treatment of the materials, avoids intersection of the treatmentworking procedures, and achieves the independence between processes.

Description

technical field [0001] The invention belongs to the technical field of vacuum sintering equipment, and in particular relates to a three-stage vacuum sintering device. Background technique [0002] At present, vacuum thermal sintering equipment is necessary equipment for the preparation of rare earth permanent magnet materials, especially NdFeB materials. Most of the vacuum sintering equipment on the market have multiple processes such as pre-vacuumizing, vacuum heating, and vacuum cooling. Some equipment completes the above processes in the same chamber, and when processing materials, each process will interfere with each other in the same chamber, which will affect the production efficiency of materials. Therefore, in the process of vacuum sintering equipment, and Many aspects such as energy consumption have great room for improvement and upgrading. Therefore, a vacuum heat treatment equipment that can divide each treatment process needs to be studied urgently. Contents o...

[0002] At present, vacuum thermal sintering equipment is necessary equipment for the preparation of rare earth permanent magnet materials, especially NdFeB materials. Most of the vacuum sintering equipment on the market have multiple processes such as pre-vacuumizing, vacuum heating, and vacuum cooling. Some equipment completes the above processes in the same chamber, and when processing materials, each process will interfere with each other in the same chamber, which will affect the production efficiency of materials. Therefore, in the process of vacuum sintering equipment, and There is great room for improvement and upgrading in many aspects such as energy consumption. Therefore, a vacuum heat treatment equipment that can divide each treatment process needs to be studied urgently.
