The performance of shear blades mainly includes the following aspects:
Blade hardness: Blade hardness is an important indicator to measure the service life and cutting effect of the blade. The higher the hardness, the longer the service life, and the better the cutting effect. The hardness of the blade is related to the material of the blade, and common blade materials include high-speed steel, hard alloy, ceramics, diamond, etc.
Blade toughness: Blade toughness refers to the ability of a blade to resist damage under impact or load. The higher the toughness, the less likely the blade is to fracture or crack. The toughness of the blade is related to the microstructure and heat treatment process of the blade material, and common heat treatment processes include quenching, tempering, quenching and tempering, etc.
Blade sharpness: Blade sharpness refers to the degree of sharpness of the blade edge, which directly affects the quality and efficiency of cutting. The sharpness of the blade is related to the grinding process and material of the blade, and common grinding processes include rough grinding, medium grinding, and repair grinding.
Blade wear resistance: Blade wear resistance refers to the wear resistance of the blade during long-term use. The wear resistance of blades is related to the hardness, toughness, and friction coefficient of blade materials. Common methods to increase the wear resistance of blades include spraying hard alloys, surface coatings, etc.
Blade accuracy: Blade accuracy refers to the dimensional accuracy and geometric shape accuracy of the blade. The accuracy of the blade directly affects the cutting quality of the shearing machine, usually guaranteed through precision machining and precision measurement.
In addition to the performance of the above aspects, the cutting machine blade also needs to consider factors such as the ease of installation and adjustment of the blade, the uniformity of the blade's stress state, and the protection and maintenance of the blade.
