The method of manufacturing a connecting rod according to the prior art includes the steps of separately manufacturing the spherical part, rod part, and pad part, and assembling the respective parts and welding and connecting the joint parts, or combining the spherical part and the rod part. The process consists of steps of manufacturing the parts as an integral structure, manufacturing the pad parts individually, and assembling the parts and welding the joints to connect them. Therefore, the manufacturing of the joint parts of the spherical part, rod part, and pad part in the connecting rod is difficult, requires a long manufacturing time, is not suitable for mass production, is expensive, and has low mechanical strength of each welded part. were small and had limited uses, causing trouble.

点があつた。 In addition, in the conventional method for producing a connecting rod, a plurality of connecting rods are welded to the outer circumferential surface of a cylindrical body using a welding means, and in the final step, the connecting rods are divided into individual connecting rod shapes. However, this manufacturing method is difficult to manufacture because the joint between the rod part and the pad part is joined by welding means, and it takes a long time to manufacture. There were problems such as low optical strength and limited use.

In the present invention, in order to solve the problems of the conventional technology, as a result of trial and error, the method for manufacturing a cooking stove as set forth in claims 1 and 2 has been completed.

Embodiments of the present invention will be described below with reference to the drawings.

A so-called star-shaped cylindrical material 18 was manufactured. Thereafter, after mounting on a mechanical device such as a lathe, the inner diameter of the cylindrical single pad portion 18 is machined to a predetermined dimension R3 .

より電気メツキの工程（電気メツキ層T2）を省
くことができる。 After machining, the star-shaped cylindrical material has gone through the steps of centrifugal casting, machining, and electroplating (not shown).
As shown in FIG. 2, the connecting rod 16 having a predetermined shape and dimensions as shown in FIG. 3 was obtained by dividing the rod into a plurality of pieces, that is, six pieces, using a saw machine or the like, as shown in FIG. (Symbol S indicates the initial cutting part) In this example, an electroplating process was added to provide the electroplating layer T2 , but depending on the use of the cooking stove, the electroplating process (electroplating layer T2 ) was added. It can be omitted.
また電気メツキ層の組成も用途により、従来公
知の例えばSn―Cu―Pb合金、Sn―In―Pb合金
などを自由に選択できる。 Furthermore, the composition of the electroplated layer can be freely selected from conventionally known, for example, Sn--Cu--Pb alloys, Sn--In--Pb alloys, etc., depending on the application.

の他所望する軸受合金などを使用してもよい。 Note that the overlay (surface layer) may be provided by other means, such as centrifugal casting, instead of electroplating. Furthermore, the type of bearing alloy is not limited to white metal; for example, copper-based bearing alloys such as copper-lead alloy (Kelmet), lead bronze, or other desired bearing alloys may be used.

も相違しており、区別できるものである。 Note that when the above-mentioned copper-based bearing alloy is used and a centrifugal casting method is adopted, the alloy structure normally exhibits a so-called dendritic structure that produces copper dendrites in the direction of cooling, but The casting method produces an almost block-like or network-like alloy structure with no directionality. Of course, the alloy structure of the former is finer and more uniform, and the bearing performance is even better. In this way, the alloy structure produced by the centrifugal casting method and the alloy structure produced by the injection casting method are different and can be distinguished from each other in all other alloys.

ろんである。 In this example, in the manufacturing process to obtain the stove rod, six pieces were processed simultaneously in each step, but without sticking to this, it was possible to change the number of pieces depending on the desired size, shape, etc.
Of course, it is possible to obtain a plurality of so-called connecting rods, such as 1, 3, 4, 5, 7, etc.
