摘要： PURPOSE:To form a poly V groove by biting the drum wall of a raw material made of plate metal only with a mountain like forming face of a groove producing roller without almost generating an upheaval on the outer circumferential face of the drum wall in a producing method of a plate metal poly V groove pulley to form the poly V grooves on the drum wall of the raw material while pressing the grooving roller on the outer circumferential face of the drum wall of the raw material made of plate metal and rotating. CONSTITUTION:A poly V groove is formed in a state of forming the clearance C2 between a rotary die 100'', 200'' and the inner circumferential face 31 of a drum wall 3. Because a mass is escaped into the clearance C2 when a grooving roller 300'' bites the drum wall 3, so the upheaval is hardly generated on the outer circumferential face of the drum wall 3. Repeating the process of the same principle, on every changing of the process, the rotary die 100'', 200'' is changed in to forming surface 101'', 201'' having smaller diameter.

摘要： PURPOSE:To surely form an ear part with a suitable shape without generating an insufficient mass in a time of forming the ear part by pressing a sharp tip forming surface for forming the ear part onto a square corner of a rough drum wall, screw-slotting the corner part and bulging an annular ear part. CONSTITUTION:An ear part forming roller 44 has a sharp tip forming surface in an annular like. Then, while an upper die 46 and a lower die 47 are rotated together with a forming body A set between them, the sharp tip forming surface 45 is pressed on the corner part of rough drum wall 15. A pressing place of the sharp tip forming surface 45 to the corner part of the rough drum wall is the place corresponding within the range of enough wall mass of a base body 10 at the inner side from the corner part. Then, the sharp tip forming surface 45 is enough bitten into the corner part of the rough drum wall 15, and the corner part is gradually screw-slotted. Accordingly, the insufficient mass is not generated, the mass is enough extended outside, and the suitably shaped ear part 16 is formed.

摘要： PURPOSE:To manufacture, without cutting and grinding, a multi-grooved V-pulley made of metal plate with the structure in which the broken sections or the surface of a base material are not exposed on the outermost circumferential part, k handling so as to avoid damage to fingers while handing the part. CONSTITUTION:A multi-grooved V-pulley is provided with a flange like ear part 3 which is expanded outward at one end in the axial direction, and the end face 31 which is a broken section of the ear part 3 is faced inward in the radial direction of the ear part 3. In the forming process of the ear part 3, the forming face in the shape of a recessed groove is pressed against a rough ear part 3', which is pressed inward in the radial direction of a body wall 1, and thereby the end face (broken section) of the rough ear part 3' is faced inward in the radial direction of the rough ear part.

摘要： PURPOSE:To prevent a rod from being put in pressure attachment to a boss part in the condition that it is plastically deformed obliquely when pressure fit of the rod to the boss part takes place while the axis of the rod is inclining to the axis of the boss part any slightly. CONSTITUTION:A rod guide part 2A has an inside diameter d1 approx. the same size as the outside diameter d2 of a rod to be pressure fitted 3 and is to locate the axis 02 of the rod 3 identical to the axis 01 of the boss part 2 of a shaping item 1 by inserting the rod 3 a certain length into the boss part 2 toward a backmore part therein from its inlet, and therein a rod pressure fit part 2C having a smaller inside diameter than the guide part 2A is formed for pressure fitting of the rod 3 to backmore in it 2A.

摘要： PURPOSE:To sufficiently enhance a reduction in weight and obtain a poly-V pulley excellent in strength by fitting a belt receiving member onto the circumferential wall of a pulley body and inserting a buried member into the pulley body at the time of molding the body. CONSTITUTION:A metal belt receiving member 1 and an embedded member 2 are obtained by forming a plurality of V channels 1a... parallel to each other, or a poly-V channel on the outer circumferential surface of a cup sheet metal member, working the bottom plate of the cup into a desired form, and boring a hole 2a in the center part. A pulley body 3 has a cylindrical form thickened in the peripheral part, a rotating shaft through hole 3a is formed in the center part, a plurality of bolt through holes 3b for connecting the poly-V pulley to the connecting member of a rotating shaft is formed, and a metal ring 4 is fitted thereto. Such a pulley body 3 is molded by charging a resin material in a space part formed in the state where an upper die A and a lower die B are provided on the upper part and lower part of the belt receiving member 1 and the embedded member 2, and at this time, the pulley body 3 is molded with the embedded member 2 being inserted.

摘要： PURPOSE:To manufacture a constituent parts for a thin and strong fluid room by forming a seal ring groove on the peripheral part of a circular steel plate member with a die assembly for forming a thick wall part and a form rolling roller. CONSTITUTION:A steel plate member A having a circular outer peripheral edge is held by a die assembly 1 for forming a thick wall part rotating round its central axis, the peripheral part of the steel plate member A is inserted into a recessed groove 3a of a form rolling roller 3 for forming a thick wall part having a recessed groove on the outer peripheral surface and pressed to the central direction to form a thick wall part a3. Then, this thick wall part a3 is held by a die 4 for forming a seal ring groove to restrain this thick wall part a3 in the central direction of the steel plate member A and a form rolling roller 52 for forming a groove having a projecting part on the outer peripheral surface is pressed to the thick outer peripheral surface to form the seal ring groove a5 for fitting the seal rings. In this way, it is possible to manufacture the constituent part for ate thin and very strong fluid room with a simple manufacturing equipment.
