Abstract

PURPOSE:To improve the rolling accuracy of a groove shape of a pin and a shaft diameter by providing two lines of rising parts whose height and width are widened gradually to the outside between the tip part and the rear end part of the surface of a flat die, and conforming the distance of the inside of each rising part conform to the wall interval between both grooves of the corresponding pin. CONSTITUTION:Rising parts 16, 18 are formed by taking the distance L of the inside of a groove G1 and G2 of a pin S on the tip part, namely, a chamfer side 12 of the surface of a flat die 10, and holding the distance L to reach the rear end, namely, a finish side 14. In this case, the height and width of the rising parts 16, 18 are formed to as to be widened gradually to the outside as they go toward the finish side 14 from the chamfer side 12, and are made to coincide substantially with the finish shape of the groove G1 or G2 of the pin S in the finish side 14. In this way, it is possible to obtain a flat die for finishing exactly the inter-core distance of both the grooves of the pin, the shape of the groove and the shaft diameter.
