What are the factors affecting the gravity lifting of the permanent magnet lifter?

July 01, 2023
1, the thickness of the workpiece and the impact of surface quality Before use, should be based on the workpiece suction plate thickness according to the performance curve, to find out the percentage of the plate thickness and holding force shown. When the surface roughness Ra is less than 6.3μm, it means that there is no gap between the workpiece and the surface of the permanent magnet lifter, and the gravity may reach 100%. If the surface roughness Ra is greater than 6.3μm, or worse, the workpiece must be measured. The gap existing in the contact with the surface of the permanent magnet lifter passes through the relationship curve between the gap shown in the performance curve and the holding force, and the percentage of lifting capacity is found. The two factors are integrated, and the permanent magnet lifting device is calculated. Achievable lifting capacity, curves on both sides of the permanent magnet lifter.
2. Influence of the material on the lifting capacity of the permanent magnet lifter The low carbon steel workpiece is taken as the reference and the lifting capacity coefficient is 1. Then the medium carbon steel is 0.95, the high carbon steel coefficient is 0.9, and the low alloy steel coefficient is 2. For 0.75, the cast iron coefficient is 0.5.
