Description

technical field [0001] The invention relates to the technical field of vacuum hot-press vibration sintering furnace, in particular to a single-direction double-action high-frequency vibration hot-press vacuum sintering furnace. Background technique [0002] At present, the working method of the vacuum hot-pressing sintering furnace is to pack the powder of ceramics, metals and some refractory metal compounds into a pre-prepared hot-pressing mold for compaction, and then put the mold and the powder into the vacuum hot-pressing sintering furnace It is directly heated and formed in the heating chamber. This processing technology is simple and convenient. However, the obtained product has low density, low strength and hardness, and poor product performance. In order to overcome these shortcomings, sintering furnaces such as cam vibration sintering furnaces, electromagnetic vibration sintering furnaces, and hydraulic vibration sintering furnaces have emerged. These sintering fu...

AI Technical Summary

Problems solved by technology

For example, the vibration amplitude and pressure of the electromagnetic vibration sintering furnace are relatively small; the vibration pressure of the cam vibration sintering furnace is difficult to control, and the service life is low; Frequency, heavy load vibration and pressurization, the equipment has extremely high requirements on the frequency response of the servo valve, and the flow rate of the servo valve is also high, resulting in high cost of the loaded hardware equipment

At the same time, the vibration direction of the above-mentioned sintering furnace generally adopts a single-acting vibration mode toward the mold, and the vibration loading pressure is much lower than the static load pressure, which directly affects the compactness of the powder
