Description

technical field [0001] The invention relates to the technical field of magnetic particle grinding and finishing, in particular to a magnetic particle grinding device and method for ultrasonically grinding the inner and outer surfaces of pipes with different diameters. Background technique [0002] The commonly used processing method of pipe fittings is stamping forming, which inevitably produces many defects such as cracks and burrs on the inner and outer surfaces of the workpiece. In our daily life, round pipes of different diameters are often used. For example, large-diameter pipe fittings are mainly used in sewers and water pipes. Our tap water is delivered to everyone’s home through large-diameter pipe fittings. Our domestic water is Inseparable from large diameter pipe fittings. Small-diameter pipe fittings also often appear in our field of vision, such as radiator pipes, various oil pipelines, etc. Pipe fittings of various pipe diameters, especially in areas with hig...

[0003] Chinese patent CN111136524A discloses a grinding and polishing device for the inner surface of the magnetic tube, which cannot process the inner and outer surfaces of the pipe at the same time, the efficiency is not high, and the magnetic abrasive grains cannot be alternately rolled, reducing the grinding effect of the magnetic abrasive grains

The manual method is time-consuming and labor-intensive and requires the processor to have a certain technical level; the electrolysis method causes the vicinity of the workpiece burr to be electrolyzed, the surface will lose its original luster, and even affect the dimensional accuracy; Processing workpieces with one diameter, and the processing efficiency is not high. If you need to process workpieces with other diameters, you need to replace different molds, and the processing cost will increase significantly.
