As shown in Japanese Patent Publication No. 56-47419, for example, such a spring assembly is made by forming a protrusion on one side of an annular plate by machining or the like, and fitting one end of the spring into the protrusion. There is a structure in which a spring is attached by expanding the protruding part.

体の製造方法である。<Means for Solving the Problems> The present invention aims to solve the above-mentioned problems and provide a method for easily manufacturing a spring assembly with high strength. The diameter of the metal plate, which is made of a narrow annular strip and is spaced apart from each other, is larger than the outer diameter of the charging end of the spring.
A large spring insertion hole and a required number of overhang holes that communicate with the spring insertion hole and overhang toward the outer circumference of the insertion hole are provided, and one end of the insertion hole is made smaller in diameter than the other part. This method of manufacturing a spring assembly is characterized in that after one end of the spring is inserted into the spring insertion hole, the metal plate is pressed and caulked from the side to fix the spring.

。<Operation> The method of the present invention will be described in detail with reference to the drawings.
From the process of inserting a plurality of pairs of spring insertion holes (2) and overhang holes (3) that communicate with each other at appropriate intervals in an annular metal plate (1) as shown in the figure. It begins. This overhanging hole (3) is provided so that caulking can be performed easily and sufficiently in the later caulking process, and is shown in (a), (b), and (2) in Figure 2.
As shown in c) and (d), one or more spring insertion holes are provided in the outer circumferential direction around the spring insertion hole (2).

ある。Next, insert one end of the spring (4), which has a smaller diameter than the other part, into the spring insertion hole (2) as shown in Figure 3, and press it from the side of the metal plate 1-(1). At this time, since the overhang hole (3) is provided, the spring insertion hole (2) itself becomes easily deformed as the overhang hole (3) deforms to become narrower. Moreover, since the spring (4) has an outward repulsive force, the inner circumferential edge of the spring insertion hole (2) is bitten into the spring (4), and a strong caulking is performed. A spring assembly as shown in Figure 4 is completed.

する事もある。In addition, in the method of the present invention, the spring (4) is a metal plate (
1), since it can be installed with sufficient perpendicularity,
After that, there is no need to grind the spring tip surface, which simplifies the process, but if even higher precision is required, the spring tip surface may be ground after assembly as shown in Figure 4. .
