Stamping device for removing black print concave lines and application method thereof

Abstract

The utility model relates to a stamping device and application method for removing black print concave lines, and relates to the technical field of shell material processing. It comprises an upper die assembly, a lower die assembly, a first driving device and a side pressing assembly. The bottom of the lower die assembly is provided with an extrusion piece. The side pressing assembly comprises a side pushing part, a side wall part and a side guide part. The bottom of the side wall part is provided with a second driving device, the bottom of the side guide part is provided with a pushing piece, and the side pushing part is provided with a plurality of protruding parts at intervals on one side of the part to be processed. Under the driving of the first driving device and the second driving device, the upper die assembly and the lower die assembly clamp the upper side and the lower side of the part to be processed, the protruding parts extrude the side wall of the part to be processed, and stamping forming is completed, thereby avoiding the generation of black print concave lines. By using the above technical scheme, the friction contact area is reduced and the force for ejecting is prevented by the action of the protruding parts, thereby preventing the accumulation of excess material, effectively avoiding the generation of black print and concave lines, improving the appearance and quality of the product, and also improving the production efficiency and reducing the cost.
