Problems solved by technology
[0002] The electric scissors in the current technology all need to use the upper knife and the lower knife to cooperate, but the upper knife and the lower knife in the prior art are generally manufactured through blanking, heat treatment and sharpening, and their wear resistance is poor. The blade becomes dull after use, requiring frequent blade replacement
[0003] In addition, since the assembly positions of the upper knife and the lower knife will directly contact and cause friction, after long-term use, the contact position will be worn and thinned, and a knife edge or gap will appear or even break, making it impossible to cut items, which has poor safety and short service life. shortcoming

Abstract
The invention relates to a replaceable electric cutter head, a blade manufacturing method and application thereof. The replaceable electric cutter head comprises a cutter head shell, an upper cutter and a lower cutter, wherein the upper cutter and the lower cutter are installed on the cutter head shell; the upper cutter is manufactured through the steps of cogging, groove milling, heat treatment, alloy inlaying, edging and the like; the lower cutter is manufactured through the steps of cogging, bending, groove milling, heat treatment, alloy inlaying, edging and the like; the wear resistance of each cutter is improved by inlaying the alloy into a blade; in the using process, the two alloys are in running-in continuously, so that the sharpness of cutting edges can be kept, and the service life of the product is prolonged; and in addition, a wear-resisting gasket located between an upper assembling part and a lower assembling part is further installed in the cutter head shell, so that direct friction between the upper assembling part and the lower assembling part can be prevented, the wear resistance of the product is further improved, and the service life of the product is further prolonged.
Description
【Technical field】 [0001] The invention relates to the technical field of scissors and knives, in particular to a cutter head of an electric scissors and a method for manufacturing the blades thereof. 【Background technique】 [0002] The electric scissors in the current technology all need to use the upper knife and the lower knife to cooperate, but the upper knife and the lower knife in the prior art are generally manufactured by blanking, heat treatment and sharpening, and their wear resistance is poor. The blade becomes dull after use, requiring frequent blade replacement. [0003] In addition, since the assembly positions of the upper knife and the lower knife will directly contact and cause friction, after long-term use, the contact position will be worn and thinned, and there will be knife edges or gaps or even breaks, making it impossible to cut items, which has poor safety and short service life. shortcoming. Therefore, it is necessary to design a cutter head with hi...
