Description

Technical Field

[0001] The utility model relates to the technical field of diamond composite sheet sintering equipment, in particular to a sealed sintering device for polycrystalline diamond composite sheets. Background Art

[0002] As we all know, polycrystalline diamond composite sheets are new functional materials. They are made by sintering diamond micropowder and cemented carbide substrate under ultra-high pressure and high temperature conditions. They have the high hardness, high wear resistance and thermal conductivity of diamond, as well as the strength and impact toughness of cemented carbide. They are ideal materials for manufacturing cutting tools, drilling bits and other wear-resistant tools. A sealed sintering device is required in the production process of polycrystalline diamond composite sheets.

[0003] In the existing process of sintering diamond composite sheets, a placement tube for diamond composite sheets is required. The diamond composite sheets are first placed in the placement tube, and then the placement tube filled with diamond composite sheets is placed in the sintering tank for sintering. However, it is very inconvenient to use traditional placement tubes when storing and taking out diamond composite sheets. For example, when the placement tube is placed horizontally, the diamond composite sheets need to be pushed into the placement tube one by one; if the placement tube is placed vertically, the diamond composite sheets placed in the placement tube will fall downward, which can easily cause damage to the diamond composite sheets; and after multiple diamond composite sheets are poured out from the placement tube, the multiple diamond composite sheets will be scattered in a messy manner, and staff need to collect and arrange the diamond composite sheets.

[0004] In summary, using a placement tube to sinter the diamond composite sheet will seriously reduce the sintering efficiency of the diamond composite sheet. Utility Model Content
