Abstract
Description
Technical Field
[0001] The utility model relates to a tungsten block sub-packaging device for a sintering tray. Background Art
[0002] Oscillator products are generally made of tungsten blocks. During the preparation process, after pressing, they need to be sintered. Generally, the oscillator products are placed on a sintering tray for sintering. However, since the tungsten blocks are not very stable and are relatively fragile before sintering, they are very likely to stick together when placed on the sintering tray, resulting in problems such as deformation of the sintered tungsten block products, and the yield of the formed products is reduced. In order to improve the sintering yield, generally, before placing them in the sintering furnace, the tungsten blocks are manually wrapped with a layer of alumina sand so that the tungsten blocks are not easily stuck together. However, this method is inefficient and the alumina sand is very likely to enter the sintering tray too much, affecting the subsequent heating of the tungsten blocks. Therefore, improvements and optimizations are made in this regard. Summary of the Utility Model
