きいという欠点があった。Automatic transmission: The ring gear flange plate used in some gear transmission equipment, etc. The flange plate is rotatably attached to a bearing on the inner periphery, and the inner periphery d3 on the inner periphery and both sides are bearing Since it is a flat abutment surface of a constant width, it has a relatively thick boss part, and conventionally, flange plates with this relatively thick boss part were manufactured by cutting. However, the disadvantages were that the production yield was low and the weight of parts was large.

By manufacturing an annular flange plate with a thick boss part, which has the purpose of use as described above, it is possible to improve productivity and reduce cost. Although it is possible to reduce the width and the weight of the part, it is quite difficult to manufacture the J:4Φ folded boss part with a predetermined uniform wall thickness and a predetermined half-t5j direction rl+ in press processing. , defects such as partial shrinkage of the wall at the tip of the quadruple fold, and thinner or thicker boss portions are likely to occur.

A roughly cylindrical protruding part is formed with a diameter gradually decreasing from the continuous part toward the tip, and the intermediate part on the base side is curved to a vertical direction with a pair ( ) to the flat plate part, and the intermediate part Approximately 1/4 of the total length of the cylindrical protrusion on the distal end that is continuous with the section.
The intermediate portion on the distal end side having a length is formed into an arcuate cross-section that curves slightly inward, narrowing at the distal end side, and continues to the intermediate portion on the distal end side to be approximately one-fourth of the total length of the cylindrical protrusion. The tip end, which is on the right side of the length, is formed into a cylindrical shape in the direction perpendicular to the flat plate part.Next, the cylindrical protrusion part A3, which has been subjected to the above burring process, is cut into an annular sheet metal with a die and a punch. They are slidably fitted to form a cylindrical space extending in the radial direction [1] equivalent to the radial direction [1] at the end of machining of the quadruple-fold boss portion to be buckled, and the cylindrical space The inner end of the cylindrical space, where the tip of the cylindrical protrusion of the annular sheet metal LF is in contact with the cylindrical protrusion 1, is compressed when the mouth line operation starts. At the start of operation, the tip is placed at a predetermined position in a buckling press mold having a curved rotary body surface for pushing and expanding the tip outward, and -
forming the inner cylindrical protrusion into a quadruple-folded boss portion having a predetermined wall thickness and a radial center by applying a buckling force T twice; and radial direction [1] dimension can be formed uniformly and with high precision.
Pressing process has the effect of reducing the number of culms.

At the time of compression operation ml 9N (1) Cylindrical protrusion A1 At the inner end of the cylindrical space to which the tip of the cylindrical protrusion of the annular sheet metal is pressed, there is a space in order to push the tip outward and expand when the compression operation starts. The inner cylindrical protrusion is placed in a predetermined position of a buckling press die in which a rotary body surface is curved, and the inner cylindrical protrusion is formed with a predetermined wall thickness and radial radius by - times of buckling. An annular flange plate with four non-folding boss parts, characterized in that the wall thickness and radial direction 11 of the four-fold boss part can be formed with high precision by - times buckling process. Manufacturing method. 2. Blank punching on the sheet metal, drawing process to make the central part protrude roundly on a curved surface multiple times and center piping process) 7), followed by burring process to create the inside)
This step of forming an annular sheet metal having a cylindrical protrusion having a predetermined and uniform length and cross-sectional shape, the annular sheet metal having an arcuate cross-section in which a continuous portion of the inner cylindrical protrusion including the outer flat plate part is curved; A base is formed in which a roughly cylindrical protrusion gradually decreases in diameter from the continuous part toward the tip, and at the middle part on the base side, it curves vertically to the flat plate part, and in the middle part. The continuous cylindrical protrusion on the distal end has a distal intermediate portion having a barb of about one-fourth of the total length, and is formed into an arcuate cross-section that curves gently inward, narrowing at the distal end. Continuing from the middle part, a tip part having a length of about 1/4 of the total length of the cylindrical protrusion is formed in a cylindrical shape perpendicular to the flat plate part, and then the burring process described above is completed. An annular sheet metal with a cylindrical protrusion is slidably fitted with a die and a punch to form a buckled quadruple-folded boss part with a diameter of "1", which is equivalent to the radial direction 11] at the end of machining. A cylindrical space having a direction 11'' is formed, and the cylindrical space is compressed and covered in the axial direction, and at the start of the compression operation, the tip of the cylindrical protrusion of the annular sheet metal comes into pressure contact with the cylindrical protrusion A. A buckling press mold is installed at a predetermined position on the inner end of the annular space in which a curved rotor surface is formed to push the tip outwardly at the beginning of the compression stroke, and - The inner cylindrical protrusion has a predetermined thickness and a radial direction of
1", and the thickness of the quadruple-fold boss part is reduced by - times of buckling process J: and 1".
A method for manufacturing an annular flange plate with a quadruple-folded boss, which is characterized in that it can be formed with high accuracy in the radial direction 1. Annular flange plate.
