Abstract

The invention relates to the technical field of electronic aluminum foil grinding, in particular to a hole grinding device. The hole grinding device comprises a concave machine frame, and a first working table with a through hole is arranged between the two longitudinal parts of the concave machine frame, and a second working table slidably matched with the two longitudinal parts of the concave machine frame is arranged on the lower part of the first working table; a positioning column slidably matched with the through hole is arranged on the upper surface of the second wording table, and a third working table slidably matched with the two longitudinal part of the concave machine frame is arranged on the upper part of the first working table; and a grinding wheel is rotatably connected tothe lower surface of the third working table, and the grinding wheel, the through hole and the positioning column are on the same axis. The hole grinding device solves the problem that after a hole ofan electronic aluminum foil is punched, the formed hole, away from one side of a punching pin, can present a crack shape on the surface of the electronic aluminum foil, and an operator injures because the crack-shape hole can scratch an operator during the transportation and operation of the electronic aluminum foil.

Description

technical field

[0001] The invention relates to the technical field of electronic aluminum foil grinding, in particular to a hole grinding device. Background technique

[0002] Aluminum foil is a hot stamping material that is directly rolled into thin sheets by metallic aluminum. Its hot stamping effect is similar to that of pure silver foil hot stamping, so it is also called fake silver foil. Due to the soft texture, good ductility and silvery white luster of aluminum, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, the aluminum foil itself is easy to oxidize and darken in color, and will fade when rubbed or touched, so it is not suitable for hot stamping on the covers of books and periodicals that are stored for a long time.

[0003] Electronic aluminum foil is a kind of aluminum foil. After the electronic aluminum foil is produced and formed, it is often necessary to punc...
