WORKING STAND STRUCTURAL ASSEMBLY AND METHOD OF PIPE OR BAR BILLET ROLLING Russian patent published in 2014 - IPC B21B13/10 

FIELD: process engineering.

SUBSTANCE: stand assembly comprises working stand (1) including main body (2), at least two pads (3, 4, 5) displacing relative thereto and furnished with rolls and/or two rocker with rolls displacing relative thereto. This assembly has mounting unit (19, 69) with main frame (23), adjustment unit and first connection part to be connected with pad and/or rocker. Said connection part can apply rolling force to roll (6, 7, 8) from adjustment unit. Pre-tensioning unit (30, 39, 59, 80) incorporates power unit to generate pressure force. Second connection part can apply the force generated by power unit to main frame (23) of mounting unit (19) to press said main frame (23) to stand main body (2). Or, pre-tensioning unit (70) has power unit that can generate unclamping force and is equipped with lengthwise thrust (75). It has also the first part (76) arranged to apply unclamping force as pressure force to stand main body (2). Second part (72) is arranged to apply unclamping force to main frame (23) of mounting unit (19) so that said main frame (23) and stand main body (2) are unclamped relative to each other for spacing defined by lengthwise thrust (75). Note here that this assembly has bearing structure (13, 48, 49, 65, 83, 93) whereon rests said pre-tensioning unit (30, 39, 59, 80).

EFFECT: higher stability of bar or pipe rolling.
