The main reasons for blade overheating during cutting are as follows:
1. * * Excessive material hardness * *: When the hardness of the sheared material exceeds the bearing capacity of the blade, the blade will withstand greater resistance during the shearing process, thereby generating more heat.
2. * * Cutting speed too fast * *: Cutting speed too fast can increase the friction between the blade and the material, generating more heat.
3. * * Inappropriate blade gap * *: Excessive or insufficient blade gap may cause blade overheating during cutting. Excessive clearance, uneven shear force, and easy generation of heat; If the gap is too small, it may increase the friction between the blade and the material, which can also lead to overheating.
4. * * Poor lubrication * *: If the blade is not properly lubricated during the shearing process, the frictional resistance will increase, causing the blade to overheat.
5. Poor blade quality: Poor blade material quality or poor manufacturing process may also cause overheating during cutting.
To reduce the problem of blade overheating during cutting, the following measures can be taken:
1. * * Choose the appropriate blade * *: Select the appropriate blade material and type based on the hardness and thickness of the cutting material.
2. * * Control shear speed * *: Based on the properties of the material and shear requirements, control the shear speed reasonably to avoid overheating caused by excessive speed.
3. * * Adjust blade clearance * *: Adjust blade clearance according to material thickness and shear requirements to ensure appropriate clearance and reduce friction and heat generation.
4. Lubricating the blade: During the shearing process, use appropriate lubricants or coolant to reduce friction between the blade and the material, and reduce heat generation.
5. * * Improve Blade Quality * *: Choose high-quality blade materials and manufacturing processes to improve the wear resistance and heat resistance of the blades.
In addition, regular inspection and replacement of blades to maintain their sharpness and integrity is also an important measure to reduce blade overheating during cutting. At the same time, comply with safety operating regulations to ensure the safety and stability of the shearing process.
