FIELD: forging.
SUBSTANCE: invention refers to cold forging of rod-shaped works with heads of ball stud type. Hollow ball stud is made of sheet bar. At the first two stages semi-finished product of barrel type is produced. Its outer diameter is equal to the largest diameter of ball-shaped head. At the following stages allowance cutting-off along open face is made. Further the operation of primary reduction and rod-shaped part reduction is made. At this, cone is formed with dimensions corresponding to the parameters of finished detail and closed head of rod-shaped ball stud is produced. Then reduction of the end for thread and calibration of rod-shaped and core pars are executed.
EFFECT: working resource increase, increase of quality of hollow ball stud.
