JPS645632A - Vertical type roll forging machine - Google Patents

Abstract

PURPOSE:To enable the rough forging and medium forging of a billet in mass quantity in succession effectively capable of taking it out by feeding to the lower part after forging by forging the billet fed in the space for forming and supported in a vertical state by the rotating forming roll abutted from the periphery thereof. CONSTITUTION:A billet A is fed 9 to an ascending billet supporting mechanism 11 in the state of each forming roll 28 retreating from the axial line (a) of a machine frame. And the forming roll A is advanced in the state of holding the blank A in an upright position and pressed to the billet a, which is thus subjected to roll forging, namely a rough forging or medium forging in the shape decided by the forming roll 28 used in order by the pressing force and rotary force of the forming roll 28. After completion of the forming, the mechanism 11 is descended by separating the forming roll 28 from the billet A to release the upper part of a blacker 12 by a projecting rod 25. The forged blank A at the part of a leg column 3 is thus dropped by releasing it. Since this forging operation is repeatedly executed in succession the rough forging or medium forging of the billet can effectively be performed.
