Detailed Description
The invention is further described below with reference to the accompanying drawings:
example (b):
as shown in figures 1 to 3
The utility model provides a crescent shear blade with high wear resistance, which comprises a blade 1, a crescent blade 2, a crescent blade back 3, a perforation module 4, a first anti-wear layer 5, a second anti-wear layer 6 and a connecting handle 7; the crescent knife edge 2 is arranged in front of the crescent knife back 3; the blade 1 is arranged in front of the crescent blade 2.
In this embodiment, specifically, the perforation module 4 is arranged in the middle of one side above the crescent knife back 3; even 7 set up in one side that crescent knife edge 2 is close to perforation module 4, even install 7 on the handle overcoat, avoid linking of scissors piece to report 7 and leak outward and cause fish tail and gouge to the workman, increased scissors piece security.
In this embodiment, specifically, the first abrasion-proof layer 5 is formed by welding a metal powder core welding wire of tungsten carbide on the outer surface of the crescent knife back 3, the first abrasion-proof layer 5 is made of a hard alloy of tungsten carbide, the hard abrasion-proof alloy of tungsten carbide has higher abrasion resistance and hardness, the overall strength of the blade is improved, the service life of the blade is greatly prolonged, when the abrasion-proof layer is seriously damaged, only the hard alloy of tungsten carbide needs to be welded, leveled and polished again, so that time and labor are saved, and materials are saved; second abrasionproof layer 6 by the welding of the metal powder core wire of tungsten carbide at 2 outside faces of crescent moon cutting edge, second abrasionproof layer is made by the carbide of tungsten carbide, the carbide of tungsten carbide possesses higher wearability and hardness, the bulk strength of blade has been improved, improve the life who improves the blade greatly, when the wearing layer damages seriously, only need carry out the carbide welding of tungsten carbide again mend the tie polish can, more labour saving and time saving, and save material.
