A die for heading long bolts contains an upper plate with a punch and a lower plate with a mould made with a central working aperture and located in a nozzle connected with a rotary bar with possibility of transverse displacement of the nozzle with mould from under the punch outside the contour of upper plate of die in the plan view, and means for pushing out the mould of stamped bolt. The nozzle and mould are conjugated by cylindrical surfaces and installed through the lower plate of the die and a press table in horizontal guides of the lower plate of die with possibility of reciprocal motion in a casing mounted in connected through grooves of the lower plate of die press table, and from the lower end of die in its working seat a pusher is introduced which is connected with a sloped surface of wedge motionlessly installed on the bottom of casing. |
