Abstract

The invention relates to a holeless riveting die. The holeless riveting die comprises an upper die base, an upper cushion plate, an upper clamping plate, a stop plate, an upper stripping plate, a lower die plate, a lower cushion plate and a lower die base, all of which are sequentially stacked from top to bottom. A core bar is arranged in the lower die plate. A forming block is arranged between the lower die plate and the lower cushion plate. Convex point structures are arranged at the bottom end of a semicircular groove in the forming block. The multiple convex point structures are arranged and are arranged in a linear array manner. The linear array direction of the convex point structures is parallel to the axis of the semicircular groove of the forming block. Each convex point structurecomprises a first convex point and second convex points. The invention further relates to a holeless riveting product formed through riveting machining of the above holeless riveting die. The riveting die is used for riveting a seam position of a cylindrical product, riveting is conducted without rivets or holes, thick or irregular protrusions can be prevented from existing at the seam position,and the high precision or roundness requirement of the product is met.

Description

technical field [0001] The invention relates to the field of riveting and moulds, in particular to a non-porous riveting mold and a non-porous riveting product. Background technique [0002] Riveting is a fastening riveting process that has been used by thousands of manufacturing companies to form or fasten sheet metal or components. With equipment using this process, the riveting head generates both pressure and mechanical movement when it comes into contact with the workpiece. [0003] In the process of stamping flat metal products to form cylindrical workpieces, most of the joints are riveted by punching or riveting. However, both stamping riveting and rivet riveting will result in thicker seams or irregular protrusions of cylindrical products. In this case, the use of punch riveting or riveting riveting is no longer suitable. Contents of the invention [0004] The purpose of the present invention is to provide a non-porous riveting mold and non-porous riveting produ...
