A plate connection method using riveting column vibration riveting pressure

Abstract

A board connection method using riveting post vibratory riveting. Before the riveting starts, the lower mold is fixed on the pedestal, and a plurality of split molds are arranged around the lower mold on the pedestal, and the upper and lower plates are stacked on the separate Put the rivet post on the upper plate, place the punch on the upper part of the rivet post, and use the vibration riveting process to apply vibration to the punch and let the punch move downward at the same time. Press the rivet post into the upper plate, the vibration on the punch is transmitted to the rivet post, the upper plate presses the lower plate and deforms downward during the deformation process, at the same time, the split mold slides radially outward along the pedestal, The sliding of the valve mold, the upper plate and the lower plate are also radially expanded and deformed under the pressure of the rivet post, and the material at the upper and lower pits of the rivet post is deformed, so that the rivet post is embedded in the upper plate , pressing the upper board to embed into the lower board near the connection point to form a buckle to realize the connection. The invention has the advantages of high connection strength, safety and environmental protection, and no damage to the board.

Description

technical field [0001] The invention belongs to the technical field of plate connection methods, and in particular relates to a plate connection method using riveting column vibration riveting. Background technique [0002] In recent years, the connection problems of plates of the same material, dissimilar materials, same thickness and different thickness have received extensive attention. The connection technology of the plates connected by rivets is poor, and the rivets will damage the surface of the plates, seriously affecting the use of the plates. In addition, because the rivets and the plates are of different materials, electrochemical corrosion is prone to occur and the connection points will become loose. [0003] Traditional spot welding will produce sparks, smoke, etc. during welding, which will pollute the environment. In addition, spot welding has poor welding performance when welding dissimilar materials, and the melting point of the spot welding material is hi...
