Description of the Related Art A metal part having protrusions that are substantially perpendicular to a plate-like portion, such as a terminal portion of a sealed storage battery, has a plate-like portion whose vertical and horizontal dimensions are different from the thickness of the protrusion. Because of its large size and small thickness, conventionally, a method of welding a projection member to a plate-shaped member or integrally molding by a precision casting method has been adopted. However, welded products and cast products have problems in mechanical strength stability and structural soundness.

め、材料歩留りが低くなるという問題がある。If the projection and the plate-like portion are integrally formed by forging, the problems of stability of mechanical strength and soundness of tissue can be avoided. However, conventional forging methods, such as upset forging, make it difficult to manufacture a plate-shaped part having a larger dimension than the protrusion, and it is extremely difficult to manufacture a plate having an asymmetrical shape. It was Further, in the case of die forging, it is difficult to avoid the formation of burrs, so that there is a problem that the material yield is reduced.

得難いという問題がある。Further, like the terminal portion of the above-mentioned sealed type storage battery, a metal part having a large vertical and horizontal dimension of the plate-like portion and a thin thickness with respect to the thickness of the protrusion is manufactured by the conventional forging method. In this case, it is necessary to perform high temperature processing such as hot forging, and it is difficult to obtain a product having good dimensional accuracy and surface quality.

ていることが好ましい。In the present invention, metal parts are manufactured by cold forging or warm forging. Warm forging is preferably performed at a temperature of 600 ° C or lower. As a result, the heating scale does not adhere to the surface of the product, and the surface quality and dimensional accuracy of the product can be improved. The material to be processed is inserted into the cavity forming the protrusion of the first mold. At this time, if the gap between the material to be processed and the cavity is large, the mounting of the material to be processed becomes unstable. Therefore, it is preferable to fit the material so that there is no rattling.

い。The second mold slides into the cavity of the first mold. Then, it is driven by a separately provided driving device to move the second mold and fit it into the cavity provided in the first mold. At this time, the end surface of the second mold comes into contact with the work piece mounted on the first mold, and the work piece is compressed and deformed. Further, when the second die is moved, the work material is plastically deformed and enters the cavity forming the plate-shaped portion to form the plate-shaped portion. When the above-mentioned processing is performed, the second mold and the first mold are in a sliding state, so that the second mold can smoothly enter into the first mold cavity.
Then, the unbalanced stress generated when the work material is deformed is supported by the sliding surface of the second mold and the first mold, which enables smooth processing. In particular, this effect is great in a product in which the plate-shaped portion is asymmetric with respect to the protrusion.
