摘要： A method and apparatus for manufacturing a legged annular member. In one aspect, a work member is formed from a ring-like raw material, and has an annular part and an outer wall part, which is formed from a leg part and a connecting part. The connecting part is removed from the work member to form an intermediate legged annular member having an annular part and a leg part. An inner diameter of the leg part of the intermediate legged annular member is expanded while a burr is removed to form a carrier, which serves as a legged annular member. Therefore, the number of manufacturing processes until completion of the carrier can be reduced, compared to performing separate processes to expand the diameter of the leg part and remove the burr. Thus, it is possible to shorten the period of time needed for completion of the carrier.

摘要： A spline member manufacturing apparatus includes a shaving punch, a shaving die, a spline punch, and a stripper. The stripper supports a first surface of a base plate portion and an outer circumferential surface of a boss portion. The shaving punch is advanced relatively, while a material and the stripper are being pressed so that cutout portions are formed in an outer circumference portion of the base plate portion by the shaving punch and the shaving die. The shaving punch is further advanced relatively while the outer circumferential surface of the base plate portion is held by the shaving die, so that a spline portion is formed by inserting the spline punch along the inner circumferential surface of the boss portion.

摘要： A method of forming a chamfered through hole having a chamfered portion at each end thereof by: forming a prepared hole in a plate-like portion; forming a first chamfered portion by driving a first punch; forming a second chamfered portion by driving a second punch, which has a second tapered surface and a generally columnar central pressing portion protruding from the center of the second tapered surface and having an annular corner at a tip thereof, and thereby forming the second chamfered portion and a central recess recessed axially inward; and punching out an unnecessary portion protruding radially inward of the prepared hole by using a finishing punch having an outer diameter equal to or smaller than that of the corner of the central pressing portion. The punching out the unnecessary portion is performed by punching from the first chamfered portion toward the second chamfered portion using the finishing punch.

摘要： Excessive increase in processing loads and damages to a thickening roller resulting from pressing the thickening roller against the blank from the outer peripheral end face are prevented, and processing of a cylindrical member having an enlarged diameter portion is made possible. With the side surface of an intermediate portion of a blank abutting and being supported on an increased diameter portion of a mandrel, a thickening roller is pressed against the side surface of the intermediate portion and moved in the radially inward direction. The blank is thus partially thickened, and the thickened portion is pressed into tooth spaces formed in a columnar portion of the mandrel, whereby splines are formed.

摘要： The disclosed method produces a spline-grooved cylindrical member, e.g. torque converter front cover, including a cylindrical portion having a target wall thickness t2, from a plate blank having a plate thickness t1. An outer peripheral portion of a disc-shaped blank is plastically deformed by pressing it against a mandrel with the concave peripheral edge of a thickness-increasing roller, so that a thick wall portion, of a thickness greater than the plate thickness t1 of the blank, is formed in the cylindrical portion. The thick wall portion is then pressed against the mandrel by forming rollers to form spline grooves therein. Thus, the other portions of the product have a wall thickness which is not unnecessarily increased. In this manner, the wall thickness t2 of the cylindrical portion is not entirely dictated by the wall thickness t1 of the blank material. Thus, a cylindrical member resistant to high pressures acting on its axially-extending outer cylindrical portion can be produced with an optimal configuration.
摘要翻译：所公开的方法产生例如花键槽的圆柱形构件。变矩器前盖，包括具有目标壁厚度t2的圆筒部分，具有板厚t1的板坯。通过将其压靠在具有增厚辊的凹形周缘的心轴上而使盘形坯料的外周部分发生塑性变形，使得厚度大于坯料板厚度t1的厚壁部分形成在圆筒形部分中。然后通过形成辊将厚壁部分压靠在心轴上，以在其中形成花键槽。因此，产品的其它部分具有不会不必要地增加的壁厚。以这种方式，圆筒部的壁厚t2不完全由坯料的壁厚t1决定。因此，可以以最佳构造来制造耐受作用在其轴向延伸的外圆柱形部分上的高压的圆柱形构件。
