1. Accurately assess the degree of wear
Check the blade regularly, and judge the wear condition by observing the wear pattern of the blade edge and measuring the difference between the blade thickness and the original size. Slight wear is manifested as small notches or slight blunting of the blade edge, which has little effect on shearing accuracy and efficiency; moderate wear causes the blade edge to become significantly blunt, with deeper wear grooves, and problems such as metal material slippage and uneven cuts may occur during shearing; severe wear causes a significant reduction in blade thickness, severe deformation of the blade edge, and even possible cracking, which seriously affects the normal operation of the equipment and shearing quality.
2. Targeted repair and replacement
For slightly worn blades, grinding can be used to repair them. Use professional grinding equipment to grind according to the original angle and parameters of the blade to restore the sharpness of the blade edge. During the grinding process, pay attention to controlling the grinding amount and grinding temperature to avoid annealing of the blade due to overheating, which reduces the hardness and wear resistance. When the blade wear reaches moderate, in addition to grinding, you can also consider using surfacing technology to weld wear-resistant materials on the worn parts, and then perform grinding. If the blade is severely worn and can no longer meet the use requirements through repair, you must replace it with a new blade in time. When replacing, choose a blade that matches the equipment model and is of qualified quality, and install it strictly in accordance with the installation specifications to ensure that the blade is installed accurately and the gap is uniform.
3. Optimize use and maintenance
To reduce blade wear, the shearing parameters of Metal Shear need to be reasonably adjusted according to the characteristics of the metal material. For materials with higher hardness, appropriately reduce the shearing speed and increase the shearing pressure to avoid aggravated wear of the blade due to excessive force at the moment. At the same time, lubricate and maintain the blade regularly, and apply special lubricant to the contact area between the blade and the knife seat to reduce friction. In addition, strengthen the daily maintenance of the equipment, check the operation of the transmission parts, ensure the smooth operation of the equipment, and prevent abnormal wear of the blade due to equipment vibration. A blade usage file should also be established to record information such as the use time of the blade, the type and quantity of sheared materials, so as to better understand the blade wear pattern and make preparations for repair or replacement in advance.
