SU1253684A1 - Working stand for tube cold rolling mill - Google Patents

Description

The invention relates to the processing of metals by pressure and can be used in the design of cold rolling stands for conical pipes.

The aim of the invention is to improve the rolling quality of variable profile pipes.

The drawing shows a diagram of the proposed working stand with a drive.

 The working stand of the cold rolling mill includes a frame 1 movable from the drive, working rolls 2 placed in it, their turning mechanism in the form of gears 3 rolls fixed on the necks and gear rails 4 in contact with them, and the axial movement of the rails containing screw gears 5 and 6 , bevel gears 7, 8 and 9, rack and pinion gear 10 and a device for adjusting the amount of movement of the rails, made in the form of a slider 11 connected to the frame with a copy groove and a pusher interacting with it) sowing movement.

The device works as follows.

The frame 1 and the slider 1 1 connected to it with a coping groove are driven back and forth from the drive. At the same time, the gears 3 fixed on the necks of the rolls 2 are wrapped around the gear racks 4 and the rolls are rotated, necessary for rolling. When moving the slider 11 in accordance with the profile of its copier groove, movement is communicated to the pusher 12 interacting with it, which through the rack gear 10, bevel gears 9, 8 and 7 and screw gears 5 and 6 transfer the movement to the rails 4, causing them to move longitudinally. . By moving the rails, the change in the rolls' rolling radii is compensated.

V

The proposed device allows, through appropriate profiling of the copier groove, to fully compensate for the measurement of the rolling radii of the rolls during the rolling of the variable profile tubes and thereby improve the quality of the rolled tubes.
