Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a stamping device with a workpiece fixing structure. Background Art

[0002] Embossing and overprinting mean the same thing, that is, one color block is overprinted on another color block. However, when printing, special attention should be paid to the overprinting of black text on color images, and the pattern under the black text should not be hollowed out, otherwise the black text will show white edges when the printing overprint is not accurate.

[0003] In the production and processing of metal parts, stamping techniques are often used to process patterns and texts on their surfaces. The existing stamping devices have a relatively simple structure, and most of them directly stamp the workpiece at a high point. This stamping method places a large load on the mold and is very easy to damage the mold; and the existing stamping devices do not have a workpiece positioning and fixing structure, which is easy to affect the processing quality due to offset.
