Technical Field

The invention relates to the technical field of workpiece surface treatment equipment, in particular to a magnetic grinding machine production line driving feeding device for surface treatment of a slender workpiece.

Background

The traditional processing industry enters an automatic and intelligent era, utilizes automatic standard elements and designs non-standard equipment, and has great promotion effects on improving the processing quality and the processing precision, improving the efficiency and reducing the labor intensity.

The prior art for grinding slender workpieces in China is solved by abrasive belt grinding. The abrasive belt grinding has the same functions of sliding, plowing and cutting as the grinding wheel, and also has the extrusion effect of abrasive particles on the surface of a workpiece, so that the plastic deformation, cold hard layer change and surface layer tearing are generated, and the temperature of a contact point is increased due to friction, so the abrasive belt grinding has multiple functions of grinding, grinding and polishing simultaneously.

In the process of grinding the abrasive belt, because the shapes and the distribution states of the abrasive grains are not uniform, the abrasive grains on the surface of the abrasive belt have the condition that the effective abrasive grains actually participating in grinding are less than the total number of the abrasive grains. Therefore, the extrusion, sliding, plowing and cutting actions of the abrasive particles on the workpiece are different in the same time, and the obtained effects are also different; due to the high-speed movement of the abrasive particles and the blunt cutting edge of the abrasive particles, large friction, elastic deformation and plastic deformation are caused in a grinding area, and large heat is generated in the grinding process, so that the surface temperature of a workpiece in the grinding area is increased, and the surface layer of the workpiece is changed. Particularly, when abrasive particles of the abrasive belt are seriously abraded, the abrasion friction is increased, a large amount of abrasion heat is generated, the temperature of the surface layer of a workpiece is rapidly increased, and the structure of the surface layer is changed.

In addition, the plastic deformation of the workpiece surface under the combined action of abrasive extrusion, sliding, plowing and the like can cause lattice distortion, density reduction, specific volume increase, and surface residual compressive stress and lower layer tensile stress can also be formed. Thus, in belt grinding, the grinding forces cause the workpiece surface to often exhibit residual compressive stresses.
