Description

Technical Field

[0001] The invention relates to the technical field of ceramic green body die cutting, in particular to a silicon nitride ceramic green body die cutting device. Background Art

[0002] Silicon nitride ceramics have high thermal conductivity, high strength, high hardness, corrosion resistance, high modulus, low expansion coefficient, oxidation resistance, and good resistance to thermal shock and mechanical shock, etc., and are considered by the material science community to be one of the ceramic materials with excellent comprehensive performance in the field of ceramics. In the preparation process of silicon nitride, the cast green body needs to be die-cut. At present, there are two major problems with the die-cutting equipment on the market. First, there will be a lot of debris when the die-cutting knife cuts the green body, which pollutes the surface of the green body; second, the transmission method is basically a roller transmission method, which will easily cause indentations on the surface of the green body.

[0003] Patent CN220428456U mentions a die-cutting mechanism of a PET polyester film slitting machine. The die-cutting device used in this patent is a metal blade. When the metal blade is used for die-cutting thick film green billets, a large number of fish scales and ports will be produced, which will cause a large number of debris problems, and therefore it cannot be used well on high thermal conductivity silicon nitride green billets.
