FIELD: process engineering. ^ SUBSTANCE: invention relates to tube rolling, particularly, to modification of cold Pilger mill stand. Said mill stand comprises reciprocating cassette and load bearing foundation including base and cover with support rails, cover position adjustment mechanism and vertical posts interconnecting said base and cover. Note here that said vertical posts are made up of four sleeves and four rods arranged concentrically and jointed together by jointing heads so that strain in rods caused by sleeve pre-compression exceeds strains caused by maximum tolerable rolling force. ^ EFFECT: ruling out deformation of foundation posts, higher quality of finished rolled stock. ^ 2 dwg |
