プーリは、通常、鋳造物を切削加工して製作されている
ので、重量が重く、かつ製作に手間がかかるとともに、
高価となつていた。[Detailed Description of the Invention] Pulleys are usually manufactured by cutting a cast material, so they are heavy and time-consuming to manufacture.
It was becoming expensive.
本発明は、板材を屈曲加工することにより、軽量なプー

る上記プーリの製造方法を説明する。A shaft hole 3 and a mounting hole 4 are bored in the end wall 4a of the boss 4. The free end of the pulley portion 2 is an open roller, and the proximal end side of the V-groove portion 5 overlaps with a folded portion 5a continuous to the opening of the boss 1. Next, a method for manufacturing the pulley according to the present invention will be explained based on FIGS. 3 to 9.
第３図に示すように、プレス加工により打抜いた、たと

第４図に示すように、プレス加工等によＶ）上記ボス１
より大径で、かつ短寸の第１次有底円筒体１に絞る。As shown in FIG.
As shown in Fig. 4, by press working etc.
The primary cylinder body 1 with a bottom is narrowed down to a larger diameter and shorter size.
ついで、プレス加工等によりｂ ボス４とほぼ等径また
はそれよりやや小径で、かつ長寸の有底円筒体に絞力、
その開口端部を、切断線Ｌより切断して、平坦に仕上げ
、所要長の第２次有底円筒体８を成形する（第６図）。Then, by pressing or the like, a squeezing force is applied to a long bottomed cylindrical body that has approximately the same diameter as the boss 4 or has a slightly smaller diameter.
The open end is cut along the cutting line L and finished flat to form a secondary bottomed cylindrical body 8 of a required length (FIG. 6).
この２次絞力は、必要に応じて、さらに追加される。第
１図におけるＡは、次工程で使用されるバルジ型を示レ
このバルジ型Ａは、上型９と左右両割型１Ｏ、ＩＤと、
摺動型１１とにより構成されている。This secondary squeezing force is further added as necessary. A in FIG. 1 indicates a bulge mold to be used in the next process. This bulge mold A includes an upper mold 9, a left and right split mold 1O, an ID,
It is composed of a sliding mold 11.
バルジ型Ａの上型９の内側上部には、前記ｖプーリのボ
ス１と等寸等形の凹孔９ａが穿設され、該凹孔９ａの開
口縁９ｂは、外上方へ向かう傾斜面となつている。A recessed hole 9a having the same size and shape as the boss 1 of the V-pulley is bored in the inner upper part of the upper mold 9 of the bulge type A, and the opening edge 9b of the recessed hole 9a is an inclined surface facing outward and upward. It's summery.
各割型１０の内面には、筒状孔１０ａが穿設され、該筒
状孔１０ａの上部要所には、浅状の内向***部１０ｂが
形成されている。A cylindrical hole 10a is bored in the inner surface of each split mold 10, and a shallow inward protuberance 10b is formed at a key point above the cylindrical hole 10a.
しかして、前記上型９の凹孔９ａと、割型１０の内向陸
起部１０ｂとにより１前記Ｖブ一りのＶ溝部５と概ね補
形をなレかつそれよりもかな力広幅の成形部が形成され
ている。Therefore, the concave hole 9a of the upper mold 9 and the inward land rising part 10b of the split mold 10 form a substantially complementary shape to the V groove part 5 of the V groove 1, and a force wider than that is formed. A section is formed.
なお筒状孔１０ａの径は、前記プーリ部２の外径とほぼ
等しい。Note that the diameter of the cylindrical hole 10a is approximately equal to the outer diameter of the pulley portion 2.
摺動型１１は、前記筒状孔１０ａ内を液密的に摺動しう
るように形成され、かつその中心には、軸線方向を向く
液圧導入孔１１ａが穿設されている。The sliding mold 11 is formed to be able to slide liquid-tightly within the cylindrical hole 10a, and has a hydraulic pressure introduction hole 11a oriented in the axial direction formed in its center.
このバルジ型Ａに、上記第２次有底円筒体８を挿入し、

続く筒部１２を備えるＶプーリ半成品Ｂが成形される。Inserting the second bottomed cylindrical body 8 into this bulge type A,
When the sliding mold 11 is press-fitted into the cylindrical hole 10a of the resistor split mold 10 by a hydraulic device or a mechanical device (not shown) and hydraulic pressure is introduced through the introduction hole 11a, as shown in FIG. As shown in FIG. 2, a V-pulley semifinished product B is molded, which includes a boss 1 of required dimensions, a gently inclined V-groove 5', and a cylindrical portion 12 following it.

図に示したＶプーリを得ることができる。本発明によれ
ば、上述のように、金属板をもつて、安価に多量製産す
ることができ、しかもその製品は、極めて軽量である。As shown in FIG. 9, this V-pulley semi-finished BOV groove 5' is pressed in the centripetal direction with an abacus bead-shaped roller 13 to form the V-groove 5, and then the lower end opening of the cylindrical part 12 is pressed. Further, if the shaft hole 3 and the mounting hole 4 are drilled at key points in the end wall 1a of the boss 1, the cutting distance will be as shown in FIGS. 1 and 2.
The V-pulley shown in the figure can be obtained. According to the present invention, as described above, the product can be mass-produced at low cost using metal plates, and the product is extremely lightweight.
また、Ｖ溝部５の表面は、ローラ加工の際に硬化するの
で、アルミニウム等の比較的軟質の加工容易な素材を使
用しても、摩耗に耐えるプーリを得ることができる。Moreover, since the surface of the V-groove portion 5 is hardened during roller processing, a pulley that is resistant to wear can be obtained even if a relatively soft and easily processed material such as aluminum is used.
さらに本発明の最も特徴とするところは、比較的小寸の
素材板を使用して、ボス１の端壁１ａと、Ｔｖ溝部５の
中心面との距離の大きなｖプーリを製フ）
造しうることである。Furthermore, the most distinctive feature of the present invention is that a v-pulley with a large distance between the end wall 1a of the boss 1 and the center plane of the Tv groove 5 is manufactured using a relatively small material plate. It is possible to do so.
すなわち、ボス１の端壁１ａと、溝部５の中心面との距
離が大きなＶプーリを板材よ勺製造するためには、円形
素材板を絞つて形成した有底円筒体の深さを、それに応
じて深いものとしなければならない。That is, in order to manufacture a V-pulley with a large distance between the end wall 1a of the boss 1 and the center plane of the groove 5 from a plate material, the depth of the bottomed cylindrical body formed by squeezing a circular material plate must be adjusted accordingly. It must be made as deep as possible.
しかして、有底円筒体の径が一定でさるとすると、その
深さを大とするためには、それに応じて大寸の円形素材
板を使用することが必要である。Assuming that the diameter of the bottomed cylindrical body is constant, in order to increase its depth, it is necessary to use a correspondingly large circular material plate.

ことができるのである。However, in the present invention, the primarily produced bottomed cylindrical body 7 is further subjected to drawing processing to form a second body having a smaller diameter and longer length.
After creating the bottomed cylindrical body 8, the bulging process is performed to bulge out key points to create the desired product. It is possible to manufacture a V-pulley in which the distance between the end wall 1a of the boss 1 and the center plane of the V-groove portion 5 is significantly larger than those processed by b-cutting or roller processing.
