Panel bonding method and panel combination component

Abstract

The aim of the invention is to provide a method for connecting two pieces of sheets, including: a step of forming a bending piece by bending a end part of a first sheet from one of the two sheets made of metal to a sharp angle relatively to a base part of the first sheet; a step of forming a bending piece by bending a end part of a second sheet from the other one of the two sheets made of metal to form an opening of the end relative to a base part of the second sheet, which opening is shorter than a maximum distance between the bending piece and the base part of the first sheet; a step of connecting the first and the second sheets, due to elastic recovery of the bending piece of the first sheet, by inserting the bending piece and the opposite base part of the first sheet into the bending piece and the opposite base part of the second sheet via the opening, and bending the bending piece of the first sheet to a further sharp angle.

Description

technical field [0001] The present invention relates to a sheet joining method for joining two metal sheets without using welding, bolts, etc., and a sheet composite member obtained by joining two metal sheets using the sheet joining method. Background technique [0002] In the process of assembling various articles, machines, structures, etc., two metal plates are generally joined by welding or joining using fastening tools such as bolts. Also, in the assembly of some articles, two metal plates are joined to each other without welding or joining by performing predetermined plastic working on the joint portion of the plates (for example, Patent Document 1). [0003] [Patent Document 1] Japanese Patent Laid-Open No. 7-232227 [0004] In general, joining methods by welding or joining have to weld or join a plurality of locations along the joining portion, so there is a problem of poor work efficiency. [0005] In addition, conventional joining methods that do not use weldin...

AI Technical Summary

Problems solved by technology

Therefore, the load concentrates on the engaging portion of the convex portion and the concave portion, and the engaging portion is easily damaged.

In addition, if the position and size of the convex and concave parts are not appropriate, the two plates will shift in position and shake

In addition, in the case of Patent Document 1, when joining two plates, the protrusions provided on one plate are press-fitted into the other plate, recesses are formed on the other plate, and these protrusions and recesses are engaged. Therefore, the position deviation of the two plates is small, but the engagement between the convex part and the concave part is shallow and insufficient, and there is a possibility that sufficient joint strength may not be obtained.
