Description

Technical Field

[0001] The present invention relates to the technical field of blank grinding, and particularly to a surface and edge grinding and cleaning device for metal stamping blanks. Background Technique

[0002] Metal stamping is a processing method that uses a mold and stamping equipment to apply pressure to a metal sheet, causing it to undergo plastic deformation or separation, thereby obtaining a part with a certain shape and size. Metal stamping applies external forces to sheets, strips, tubes, profiles, etc. through a press and a mold, causing plastic deformation or separation to obtain workpieces with the required shape and size. The three elements of stamping processing include sheet material, mold, and equipment. Metal stamping has a wide range of applications in multiple fields, including automobile manufacturing, aerospace, healthcare, electronic equipment, etc.; The metal blank needs to be ground before stamping to avoid the uneven surface of the blank affecting the quality after stamping. When grinding the blank, the edges and corners need to be processed. When processing the edges and corners of the blank, the operator needs to hold the blank by hand and press the blank against the surface of the grinding device to process the edges and corners. The friction generated during grinding is relatively large, which easily causes the blank in the operator's hand to fall off, posing a greater risk. Summary of the Invention
