Application performance of mechanical blades
1. High hardness and wear resistance
Hardness is a basic characteristic of mechanical blade materials. For mechanical blades to cut chips from the workpiece, the hardness must be greater than the hardness of the workpiece material. The cutting edge hardness of mechanical blades used for cutting metals is generally above 60HRC. Abrasion resistance is the ability of a material to resist wear. In general, the higher the hardness of the mechanical blade material, the better its wear resistance. The higher the hardness of the hard spots (carbides, nitrides, etc.) in the structure, the greater the number, the smaller the particles, and the more uniform the distribution, the better the wear resistance. Wear resistance is also related to the chemical composition, strength, microstructure and temperature of the friction zone of the material. The formula can be used to express the wear resistance of the material WR: WR=KICO.5E-0.8H1.43 where: the higher the hardness of the material (GPa) and the higher the hardness, the better the wear resistance.
2. Sufficient strength and toughness
In order for the mechanical blade to work under high pressure and under the impact and vibration conditions that often occur during the cutting process without chipping and breaking, the mechanical blade material must have sufficient strength and toughness.
3. High heat resistance (thermal stability)
Heat resistance is the main indicator to measure the cutting performance of mechanical blade materials. It refers to the performance of mechanical blade materials to maintain a certain hardness, wear resistance, strength and toughness under high temperature conditions.
The material of the mechanical blade should also have the ability to resist oxidation at high temperatures and good resistance to adhesion and diffusion, that is, the material should be of good chemical stability.
4. Good thermal physical properties and thermal shock resistance
The better the thermal conductivity of the mechanical blade material, the easier the cutting heat is dissipated from the cutting zone, which is helpful to reduce the cutting temperature.
When the mechanical blade is cut intermittently or when cutting fluid is used, it is often subjected to a large thermal shock (the temperature changes drastically). Therefore, a crack may occur inside the mechanical blade and cause fracture. The ability of the mechanical blade material to resist thermal shock can only be expressed by the thermal shock coefficient, and the definition of R is: R = into ab(1-u)/Ea
In the formula: Enter one by one thermal conductivity;
ab one by one tensile strength;
Ning Baisong ratio;
E one-one elastic modulus;
a—The coefficient of thermal expansion.
Large thermal conductivity, easy to dissipate heat, reduce the temperature gradient on the surface of the mechanical blade; small thermal expansion coefficient, can reduce thermal deformation; small elastic modulus, can reduce the magnitude of alternating stress due to thermal deformation; is conducive to material resistance Improved thermal shock performance. For the mechanical blade material with good thermal shock resistance, cutting fluid can be used for cutting.
5. Good process performance
In order to facilitate the manufacture of mechanical blades, mechanical blade materials are required to have good process performance, such as forging performance, heat treatment performance, high-temperature plastic deformation performance, grinding processing performance, etc.
Economic efficiency is one of the important indicators of mechanical blade materials. Although the cost of high-quality mechanical blade materials is high for a single piece of mechanical blade, the cost allocated to each part is not necessarily high due to its long service life. Therefore, it is necessary to comprehensively consider its economic effect when selecting mechanical blade materials
