Description

本考案は、金属と金属どうしを結合する際の構造に関するものである。The present invention relates to a structure for joining metals to each other.

従来、金属どうしの結合においては、溶接するか、金属面どうしの両側に穴をあけ、ピンを入れる圧入による結合方法で、この際、接触面の面取りはせずに結合させていた。Conventionally, in the joining of metals, the joining method is by press-fitting by welding or by drilling holes on both sides of the metal surfaces and inserting pins. At this time, the joining is performed without chamfering the contact surfaces.

溶接による金属どうしの結合は、溶接部分に跡が残ってしまう。また、金属面どうしの両側に穴をあけ、ピンを入れる圧入による結合も面取りをせずに結合すると接着面が点どうしの接触となり、結合材のピンが表面に見えてしまう。従って、金属どうしの接触面の面取りをしてから結合することにより、密着強度を増すとともに、ピンを表に見せず仕上げることが可能になり、前述の欠点を解決しようとするものである。When metal is joined by welding, a mark remains on the welded portion. In addition, when holes are formed on both sides of the metal surfaces and the connection by press-fitting to insert the pins is performed without chamfering, the bonding surfaces are in contact with each other, and the pins of the bonding material appear on the surface. Therefore, by chamfering the contact surfaces of the metals and then bonding them, the adhesion strength can be increased and the pins can be finished without showing them on the surface, and the above-described drawbacks are to be solved.

金属どうしを結合する際、主となる胴部の面形状に合わせて他方面を削り、接着面の両側に穴をあけピンを入れ締め込んで圧入することで、接着面を隙間なく結合させ、結合材のピンを表に見せず仕上げることにより問題点を解決している。When joining metals, the other side is shaved according to the surface shape of the main body part, holes are drilled on both sides of the adhesive surface, and pins are inserted and pressed in to join the adhesive surfaces without gaps, The problem is solved by finishing the pins of the binding material without showing them on the table.

上述のように、本考案の構造は、金属どうしの結合をより美しく仕上げ結合強度を増すのに役立つ。As described above, the structure of the present invention helps to improve the bond strength by finishing the bond between metals more beautifully.

本考案の構造の一実施例である。It is one Example of the structure of this invention. 図１の完成形を示す図である。It is a figure which shows the completion form of FIG.

金属どうしの平面と曲面、曲面と曲面を結合する際、平面と曲面の場合は、曲面側の接触面を平面胴部の面形状に合わせて削り、曲面と曲面の場合は、主となる曲面胴部の面形状に合わせて他方曲面を削り、接着面の両側に穴をあけピンを入れ締め込んで圧入することで、接着面を隙間なく結合させる。When combining flat surfaces and curved surfaces between metal surfaces, and curved surfaces and curved surfaces, if the surfaces are curved surfaces, the contact surface on the curved surface side is shaved to match the surface shape of the flat body, and if curved surfaces and curved surfaces, the main curved surface The other curved surface is cut in accordance with the surface shape of the body portion, holes are formed on both sides of the bonding surface, pins are inserted and tightened, and the bonding surface is joined without a gap.
