Plate connecting method capable of using prepressing holes of soft rivet column and riveting compounding

Abstract

The invention discloses a plate connecting method capable of using prepressing holes of a soft rivet column and riveting compounding. The plate connecting method comprises the following steps: a connecting point is generated on an upper plate and a lower plate by adopting the prepressing holes, mechanical deformation is generated between the upper plate and the lower plate to form embedment, and thus the upper plate is connected with the lower plate together; the connecting point formed by connecting the upper plate and the lower plate through the prepressing holes is reversely buckled up on the rivet column to ensure the rivet column to be arranged in a pit formed in the upper plate; the upper plate, the lower plate and the rivet column are arranged between an upper mold and a lower mold; the upper mold moves downwards through a riveting process and extrudes the upper plate, the lower plate and the rivet column with matching of the lower mold, so that the rivet column has plastic deformation, is embedded into the upper plate and presses the upper plate to be further embedded into the lower plate at the connecting point to ensure increase of the connecting strength; and the height of a salient formed on the lower plate lowers under the pressure action of the upper mode. The plate connecting method has the advantages of high connecting strength and low salient height.

Description

technical field [0001] The invention belongs to the technical field of plate connection, and in particular relates to a plate connection method using soft riveting posts combined with pre-pressed holes and 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] In addition, there is a technology for connecting plates called mechanical deformation pressure connection process. The mechanical deformation pressure connection process uses a special punch and die to stamp the connecting plates, and...

AI Technical Summary

Problems solved by technology

The traditional mechanical deformation pressure connection process cannot be used in occasions that require relative sliding of planes due to its protrusions, which limits its wide application

In addition, due to the pits and protrusions on both sides, it seriously affects its aesthetics, making it impossible to use in occasions that require high quality on the appearance.
