Description

technical field [0001] The invention is applied in the background of stamping equipment, the name is pressing device for metal bookmark production line. Background technique [0002] Metal bookmarks, as the name suggests, are bookmarks made of metal. Because metal bookmarks break the traditional paper bookmarks, they have a more metallic texture and are used more and more widely. They are more used as gifts and collectibles. The production of metal bookmarks is generally After stamping, polishing, electrophoresis, silk screen printing, wire drawing and other processes, stamping is the key process of forming metal bookmarks. This process needs to press the preset pattern on the metal surface to form a concave structure, and then paint on the reverse side to form a beautiful bookmark. pattern to increase the three-dimensionality of the metal bookmark. [0003] However, at present, the production of metal bookmarks is made of soft copper sheet metal, and the copper parts are r...

AI Technical Summary

Problems solved by technology

[0003] However, at present, the production of metal bookmarks is made of soft copper sheet metal, and the copper parts are relatively viscous due to the high temperature during the stamping process, which is easy to Adhesion to the tool and cause local defects, thus destroying the overall beauty of the pattern, so the die-cut part needs to be cooled
