Embodiment Construction

[0102] Such as figure 1 As shown, a cutting module 1 for a hair or hair electric clipper generally includes two knives 2 and 3, which are controlled by an unillustrated and skilled person in an alternating translational movement relative to each other. Well-known mechanism drives. Often the lower cutter 2 is fixed relative to the base of the clipper, while the upper cutter 3 is movable relative to the lower cutter 2 .

[0103] The stationary knife 2 comprises a main body 4 from which extends a set of teeth or blades 5 each having a generally triangular shape, such as figure 1 shown. Likewise, the movable knife 3 comprises a body 6 carrying a set of teeth 7 each also of generally triangular shape. Unlike the blades 5 of the stationary knife 2 , the teeth 7 of the movable knife 3 according to the example each have two sharp edges which form the sides of a corresponding triangle. Of course, the teeth 5 of the stationary knife 2 can also have sharp edges.

[0104] The tooth 7...

Abstract

This invention relates to a cutter for hair trimming, comprising main bodies (5,7), and a pair of teeth (5,7) extending from bodies (4,6). The pair of teeth (5,7) possess blades and surfaces in contact with the teeth. The cutter is characterized by being made of a self-lubricating material and solid lubricant particles scattered in the base material. The self-lubricating material comprises a base material which is selected from metal, metal alloy, ceramic, ceramic mixture and the mixture of all the materials. The solid lubricant is selected from the molybdic sulfide MoS2, tin Sn, copper Cu, zinc Zn, lead Pb or the metal alloy of silver Ag, borazon BN, graphite and the mixture of the above mentioned.

Description

technical field [0001] The invention relates to the technical field of manufacturing mechanical parts for contacting other mechanical parts in motion. In a preferred but not exclusive application, the invention relates to the field of manufacture of cutting tools, such as cutting tools especially for carrying out shearing work in pairs, such as motorized or non-motorized hair or hair clipper blades. Background technique [0002] As described in patent application FR2892902, the cutting module of an electric clipper generally comprises a fixed knife cooperating with a movable knife supported on the fixed knife and oscillating relative to it. The stationary knife comprises a body from which extends a set of teeth, the edges of which need not be sharp. The movable knife itself also includes a body from which extends a set of sharpened teeth. For reasons of sharpness, durability and even aesthetics, movable and stationary knives are generally machined or stamped from metal. I...
