This invention relates to a coupling method for fixing seven flanges provided in the axle housing to both ends of the axle housing, etc.

If the diameter does not match the diameter of the fitting hole provided on the 7 lange side, by adding padding to both ends of the axle housing, etc., the diameter of the fitting hole will be larger than that on the 7 lange side. By forming a bead part and scraping off a part of the bead part, the diameter of the 7 lange is made to match the diameter of the 7 lange side, and by fitting the 7 lange to the bead part, it is possible to fit the 7 lange to both ends of the axle housing, etc. In the method for obtaining a seven-lunge connection, the object is to obtain the bead portion integrally by upsetting and coining the both ends of the axle housing or the like at the same time.

側の嵌合孔と一致させる方。Generally, seven langes for attaching a hub wheel to the axle housing are connected to both ends of the axle housing. In order to connect this 7 lange to both ends of the axle housing, etc., the fitting hole is made R on the flange side so as to correspond to both ends of the axle housing, etc., and the axle housing, etc. is connected through the ti hole. Although a method of fitting both ends is generally used, it is extremely difficult to match the diameter of the fitting hole on the 7-lunge side and the diameter of both ends of the axle housing or the like. Therefore, it is necessary to match both ends of the axle housing, etc. with the fitting holes on the 7 lange side. Conventionally, the method of matching the fitting holes on the 7 lange side with both ends of the axle housing, etc. By forming the fitting hole on the flange side to be slightly larger in diameter than both ends of the axle housing, etc., and adding padding to both ends of the axle housing, etc., the fitting hole on the 7 lange side can be easily fitted. After machining it so that it has a larger diameter than the hole, a part of this built-up part (bead part) is shaved off by circular machining to match the fitting hole on the 7 lange side.

損われる点に問題点を有する。law is used. Specific methods for forming bead portions on both ends of an axle housing, etc. include directly applying build-up by welding, or fixing small pieces by welding, etc.
Both of the above methods are laborious because they are both done manually, and the workability is poor, such as the amount of overlay on the bead being likely to be uneven, and the post-work process of rounding to a perfect circle being time-consuming. In addition to the above problems, the welding heat dulls both ends of the axle housing, resulting in changes in the material and deformation, which impairs the quality of the axle housing.

せる様に構成したことにある。The present invention attempts to improve the conventional problems as described above in order to solve them. That is, the present invention attempts to improve this in view of the fact that axle housings and the like are subjected to upsetting in order to form thicker parts at the necessary upper portions to provide strength at both ends thereof. The bead part is made to bulge out as a whole through the pressing force during the upsetting process, and more specifically, the upsetting process is achieved by providing a concave and convex strip for forming the bead part in the upsetting mold. The feature is that a bead portion is formed at the same time. The gist of the present invention is that the cap is formed into a cylindrical shape with a bottom, and the core metal is inserted into the center of the cap with an upsetting space between the cap and the inner wall surface of the cap, and the outer periphery of the core metal is inserted into the center of the cap. An upsetting mold is installed on the axle housing, etc., in which a plurality of protruding stripes are provided protruding along the longitudinal direction of the cap, and a plurality of four stripes are engraved on the inner periphery of the cap in correspondence with the protruding stripes. The molds are placed facing each other at both ends of the axle housing, and both ends of the axle housing are pressed in opposite directions while the ends of the axle housing are inserted into the upsetting space. The structure is such that the thick portion bulges toward the inner periphery and the plurality of bead portions bulge toward the outer periphery.
