Abstract

PURPOSE: To manufacture a socket wrench of high accuracy at low cost in a mechanism wherein annealed wrench blank material is inserted into the upper hole of the drag, and the first cold forging process is performed by a forming hammer equipped with a protruded lug, while the second process is performed by a forming hammer equipped with an angle hole.
CONSTITUTION: A wrench blank material 3, which is made of steel bar 2 with appropriate length and of a diameter d equal to that of the larger diameter 1 of the socket wrench A, is inserted into the upper hole 4 of the drag 7 for forging, after being annealed, and its smaller diameter part 5 is swelled out by applying pressure dropping upon it the hammer 11 which is provided with continuous protrusions 9 around the lower portion of the outer circumference, while the insertion holes 13 for bolts and the like having continuous protrusions 12 are formed around the inner surface of the larger diameter portion 1. Then, the hammer 15 equipped with an angle hole forming part 14 at its bottom is dropped by pressure, and the handle insertion hole 17 is formed leaving bottom 16 at the lower end within the smaller diameter part 5. The semi-finished product on which the first and the second processes are thru, is taken out from the drag 7, and the insertion hole 17 is penetrated after the machinework is completed.
