FIELD: rolling equipment and processes, namely additional equipment of shape bending mills. ^ SUBSTANCE: uncoiler, mainly to commercial light type section bending mill includes mounted in struts lateral crosspieces-limiter of predetermined size made with possibility of changing distance between them along horizon. In inner surfaces of crosspieces cylinder-cone rollers are mounted in pivots. Said rollers extend along 0.53 -0.58 of length l of one branch of each crosspiece. Diameter of cylindrical portion of roller may consist 0.75 -0.80 of its height h = (0.110 - 0.115)l. Inclination angle of generatrix of cone portion of roller to its axis may be in range 30 - 38°. ^ EFFECT: reduced expenses for realizing manufacturing process due to lowered quantity of waste metals. ^ 3 cl, 2 dwg, 1 ex |
