この発明は、多条Ｖ溝プーリの製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a multi-thread V-groove pulley.
この種の多条Ｖ溝プーリの製造方法として特願
昭58−90403号に係るものが先に本出願人により
提案されている。
A method for manufacturing this type of multi-thread V-groove pulley was previously proposed by the present applicant in Japanese Patent Application No. 58-90403.

造成形する工程（同図Ｄ）とを含んでいる。 According to Japanese Patent Application No. 58-90403, as shown in FIG. ), a process of pressing the rotating slotted roller 1 onto the material Q to compress and increase the thickness of the material Q in the radial direction while slotting the outer peripheral end surface into a substantially V-shape to form the slotted groove S 1 (the same figure). B), the step of expanding the slotted groove S1 into a substantially trapezoidal cross-section with the preforming roller 2 to form the V-groove portion S2 (FIG. C), and the step of further forming the V-groove portion S2 with the forming roller 3. The process includes a step of rolling into the V-groove S3 (D in the same figure).

底面に成形ローラ３を押し付けて一気に多条Ｖ溝
部S3を転造成形することから、左右方向から捲込
みが起こつて最終形状の山部ｍの頂部に成形欠陥
であるトツプロールが発生しやすい。 According to such a conventional manufacturing method, as shown in FIGS. 1C and 1D, the forming roller 3 is pressed against the bottom surface of the V-groove S2 having a substantially trapezoidal cross section to form the multi-strip V-groove S3 at once. Because of the shape, rolling occurs from the left and right directions, and a top roll, which is a molding defect, is likely to occur at the top of the peak m in the final shape.
そこで、上記のようなトツプロールを抑制する
ことを目的として、第１図Ｃの予備成形ローラ２
に代えて第２図Ｃに示すような波形成形面１２ａ
を有する予備成形ローラ１２を用い、Ｖ溝部S2の
底面を断面波形状の波形形状面Ｗに成形する方法
が本出願人により提案されている。 Therefore, for the purpose of suppressing the above-mentioned top roll, the preforming roller 2 of FIG.
Instead, a waveform shaped surface 12a as shown in FIG.
The applicant has proposed a method of forming the bottom surface of the V-groove portion S2 into a wave-shaped surface W having a wave-shaped cross section using a pre-forming roller 12 having the following.

なる。 According to such a method, although the occurrence of top rolls is suppressed, the overall distribution of the material thickness is still insufficient, and variations in the diameter of the top of the peak m are likely to occur. In other words, in the slotting process shown in Figure 2A and B, the material thickness may not be distributed accurately to the left and right from the center line in the plate thickness direction, and also in the preforming process shown in Figure 2C. Since the top of the preforming roller 12 comes into contact with the slope of the groove S1 , the flow of the material becomes unstable, and as a result, due to the synergistic effect of the above two points, the diameter of the top of the peak m of the final product shape varies. will occur.

The present invention distributes the material thickness between each valley of the final product in advance by forming slot grooves with a step-like cross section toward the deepest part in the slotting process. It is characterized in that the portion of the split groove that will come into contact with the top of the preforming roller in the next step is formed so that the cross section is a plane substantially parallel to the rotation center axis of the material.

形成する。 First, as shown in FIGS. 3A and 3B, a disc-shaped material Q is held between a rotary press mold and a rotary receiving mold of a molding device (not shown), and then a slotted roller 4 that rotates together with the material Q is held. is pressed to increase the thickness of the peripheral edge of the material Q in the radial direction while slitting the outer peripheral end surface into a substantially V-shape. In other words, in the slitting process, the forming surface 4a whose cross section is a multi-stepped mountain shape is used as a roller.
By using the slotted roller 4 having a groove, a slotted groove S11 having a step-shaped cross section toward the deepest part is formed.

肉量とそれぞれ等しくなるように予め配分する。 This slotted groove S11 , which has a stepped cross-section, includes, in its cross section, a flat portion F that is approximately parallel to the rotation center axis of the material Q, and these flat portions F correspond to the respective top portions m1 of the preforming rollers 22 in the next step. On the other hand, as shown in Fig. 4, the amount of material in areas a to f divided by the center l of each plane part F is set to correspond to the valley in the final product shown in Fig. 5. The material thickness is distributed in advance so as to be equal to the material thickness of the regions a1 to f1, which are divided by section.

At this time, the top m of the preforming roller 22
1 corresponds to the center of the flat part F (Fig. 4), and the relationship between the peaks and valleys of the waveform surface W formed on the material Q side is the same as the multi-row V of the final product shape.
This corresponds to the relationship between the peaks and valleys of the groove S 33 (Fig. 3D).
