Ceramic knife and manufacturing method thereof

Abstract

The invention discloses a ceramic knife and a manufacturing method thereof. The ceramic knife comprises a plastic hilt, a ceramic blade and a metal piece, wherein, the ceramic blade is spliced in the plastic hilt through a connecting sheet; the metal piece is arranged in the outer position of the connecting sheet; a position equipped with the metal piece on a structure to be heated is heated through a thermatron when the ceramic knife is manufactured, molten plastic material is welded on the metal piece and the connecting sheet, and the ceramic knife is obtained after the molten plastic material is cooled down. The ceramic knife has a simple structure, the connection stability between the ceramic blade and the plastic hilt is easy to control, the finished product ratio is high, the manufacture effect can be controlled effectively, the manufacturing cost can be lowered greatly, the firm degree of formed structure is improved greatly by compared with the gluewater connection, the ceramic knife also has the advantage of compact and beautiful appearance, and the installing and fixing speed of the ceramic knife can be increased greatly; in addition, the metal piece in the ceramic knife can be detected through a metal detector when security inspection is carried out, so that safety accidents caused by the ceramic knife can be avoided.

Description

technical field [0001] The invention relates to a cutting tool and a manufacturing method thereof, in particular to a ceramic knife with a new structure and a manufacturing method thereof. Background technique [0002] As a high-tech product, ceramic knives have advantages that traditional metal knives cannot match. Among them, the hardness of ceramic knives is only smaller than the hardest diamond in the world, and there will be no wear and tear during use. Generally, there is no need to sharpen the knife, and it is convenient and durable to use. In addition, because the density of the ceramic knife is quite high, its surface has no capillary pores, so the food obtained by using it for cutting does not leave any peculiar smell or metallic taste. In addition to the above description, ceramic knives also have the advantages of anti-magnetization, anti-oxidation, no rust, and easy cleaning. [0003] At present, the structure of ceramic knives is generally composed of ceramic...

AI Technical Summary

Problems solved by technology

The disadvantage of the former method is that the injection molding handle is prone to breakage, dislocation, deformation, etc., and the scrap rate is very high. Considering the high price of zirconia materials used to make ceramic blades, the high scrap rate will seriously affect ceramics. The production cost of the knife; the disadvantage of the latter method is that the adhesion is not strong, the glue waits for a long time to dry, so the production efficiency is very low, and because the characteristics of the glue are difficult to control, the glue will easily flow outside the ceramic knife, After drying outside, it will seriously affect the appearance of the finished ceramic knife

[0005] To sum up, the current ceramic knife products have various defects due to the influence of their own structure or manufacturing process, and they can be improved in terms of security, knife body stability, production cost, etc.
