FIELD: plastic metal working, namely cogging and billet hot rolling mills. SUBSTANCE: assembly of upper and lower slides that are mutually embraced with possibility of motion one relative to another is arranged in housing 1. Upper slide 4 is mounted on main journals of eccentric shaft 5. Split sleeve 6 is placed in turning of lower support 7. Said split sleeve is mounted on eccentric journals of shaft 5. Outer diameter of sleeve 6 is determined according to expression: <EMI ID=0.32 HE=6 WI=27 TI=CHI>, eccentricity value of sleeve epsi = e/2=e/2. Sleeve 6 is fixed against rotation in lower slide 7 by means of wedge keys 10. Use of said split eccentric sleeve allows to eliminate parting of lower slide and provides increased rigidity and strength of lower slide. EFFECT: improved design. 2 cl, 2 dwgi
