Abstract

The invention discloses a method of riveting heavy and medium metal sheets without projections on double faces and belongs to the technical field of material connection. The heavy and medium metal sheets are riveted quickly and efficiently by adopting a method of prefabricating holes with annular grooves in the two to-be-connected heavy and medium metal sheets and placing simply shaped connectingcolumns into the holes, and applying external forces to two sides of the connecting columns through upper and lower punches, wherein the connecting columns deform plastically to fill the annular grooves. According to a volume invariable law, the connecting columns which deform plastically can be filled into the annular grooves of upper and lower panel veneers without obvious protruding height points, so that the grinding step is reduced and the production efficiency is improved. The used parts of the device are simple in structure, convenient to process and good in compatibility with conventional equipment, the pre-treatment process of the to-be-welded panels is simple, the production efficiency is high and the cost is low. The surface of the connected part is smooth and is free of projections, so that the heavy and medium metal sheets are more attractive. Furthermore, after the connecting columns deform plastically, the tensile strength and the shear strength of the riveted part are improved and the connection is more stable.

Description

technical field [0001] The invention belongs to the technical field of material connection, and in particular relates to a riveting method for double-sided medium-thick metal plates without protrusions. Background technique [0002] Medium-thick metal plates usually refer to metal plates with a thickness of 4mm to 20mm. Medium-thick metal plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. [0003] At present, the connection of medium-thick metal plates is usually conventional methods such as bolt connection, pressure riveting, pull rivet and other rivet connections, but there are problems such as protrusions on the surface, which affect the appearance, and the bolts are easy to loosen, resulting in failure of the connection. At the same time, in some specific occasions, the surface of the riveting part is required to have no protrusions and the surface is smooth, making it ...
