る。By the way, in the conventional method in which the leg pieces bent to one side plate of the planetary carrier are inserted into the engagement holes formed in the other side plate and welded, the other side plate is formed into the engagement hole. It is necessary to form a large diameter in order to secure a forming space, which causes a problem that the carrier becomes large. In this case, it is conceivable that the leg pieces are abutted against the outer peripheral edge portion of the opposite surface of the other side plate to the one side plate and welded, but as shown in FIG. When the cylindrical portion c extending to the opposite side to the opposite direction is press-molded, the outer peripheral edge portion of the opposite surface of the other side plate b to the one side plate a becomes a rounded portion curved toward the cylindrical portion c, and A portion of the tip of the piece d near the outer edge in the radial direction floats from the side plate b. Therefore, the leg piece d has to be welded to the side plate b only at the portion near the radial inner edge of the tip end, which makes it difficult to secure the welding strength, and further, the leg piece d that serves as the thrust receiving surface of the planetary gear. The welding spatter scatters on the radially inner part of the joining portion of, and a spatter removing step is required. In view of the above points, the present invention is a method for manufacturing a planetary carrier, in which a leg piece bent to one side plate can be welded favorably to the outer peripheral edge part of the facing surface of the other side plate press-molded on the tubular portion. Its purpose is to provide.

図れる。The flat seating surface is formed by coining even if the outer peripheral edge of the opposite surface of the other side plate to the one side plate is rounded by press molding of the cylindrical portion, and the leg pieces have their entire tip ends. The seating surface can be welded to the seating surface in close contact with the seating surface, and the coining edges prevent the welding spatter from scattering radially inward at the joint of the leg pieces. Further, by forming the seat surface in a predetermined phase, both side plates can be phase-matched and joined with the seat surface as a reference. Although it is conceivable to form the seat surface by cutting, if the seat surface is formed by coining as in the present invention, the seat surface can be formed by coining in the press step of forming the tubular portion. To reduce costs.

The press die includes a lower die 100 and an upper die 101 which is moved up and down, and a die 102 for externally fitting and setting the side plate 51 on which the tubular portion 51a is preformed in a downward direction on the lower die 100,
A plurality of tooth-shaped punches 103, which are located around the die 102 and can move back and forth in the radial direction as shown in FIG. 6, are provided.
A pad 104 for pressing the side plate 51 onto the die 102 is attached to the upper die 101 by urging it downward with a spring 104a, and a driver cam 105 for vertically pushing the tooth-shaped punch 103 in the radial direction is provided vertically. A tooth groove 102a corresponding to the serration teeth 55 is formed on the outer peripheral surface of the die 102, and when the upper die 101 is moved downward, the tooth profile punch 103 is pushed inward in the radial direction via the driver cam 105. The cylindrical portion 51a is pushed into the tooth groove 102a by 103 so that the serration teeth 55 are press-molded. Further, as shown in FIG. 7, a protrusion 104b for coining is provided on the lower surface of the pad 104, and the side plate 51 is kept in a shut height state. Of the protrusion 104 on the outer peripheral edge of the upper surface that is the opposite surface of the
The seating surface 54 is coined by b.

してコストダウンを図れる。As is apparent from the above description, according to the present invention, the outer peripheral edge portion of the facing surface of the other side plate to the one side plate of the planetary carrier is formed by press-molding the tubular portion on the other side plate. Even if it becomes a rounded part by forming a seat surface at a predetermined phase on the outer peripheral edge part, a leg piece bent to one side plate is formed on the seat surface in the state where both side plates are aligned with each other. It is possible to butt weld well to the peripheral edge, and further, it is possible to prevent the spatter of welding spatter to the radially inner part of the joint part of the leg piece, eliminating the spatter removal step and forming the seat surface by coining. Therefore, the seating surface can be formed in the pressing process of the other side plate, and the number of steps can be reduced and the cost can be reduced.
