Abstract

This invention relates to metallurgy, in particular, to devices. constructively coupled with rolling mills, and can be used in the production of shaped profiles. The purpose of the invention is to improve the quality of finished rolled products by increasing the longitudinal stability of the roll. The fitting of the size of the profile of all pairs of vertical rolls is done by turning the studs 10. The rollers 3 move with their axes in the guides 11 of the bearing plates 2. The hinges 19 move in the guides 12, Roll 18 is held at the inlet and outlet by the auxiliary rolls 4. This ensures high stability of the roll and eliminates the distortion of the shape of the shelves. 1 il. with (L ate 1C 75 №

Rolled

The aim of the invention is to improve the quality of finished rolled products by TJ-EM to increase the longitudinal stability of the roll.

The drawing shows schematically a cassette with vertical rollers. The cassette with vertical rollers contains a housing 1, carrying plates 2 between which the main vertical rolls 3 are located at a distance H from each other equal to the height of the channel, the axes 4 of which are connected to the base 5 of the auxiliary vertical roll 6 by the levers 7 of the parallel system Lelogram mechanisms of the Nyur- |) yerg scissors on Axis 5, the auxiliary vertical rolls 6, the distance between which is also equal to h -: the height of the channel, are equipped with nuts 8: i 9, having the opposite thread, and are connected by a pin 10. Bearings gyts 2 have guides 11 and 12, the working surfaces 13 and 14 of which are directed along the diagonal m KN and FM of the quadrilateral FKMN, formed by the levers 7 of the Nürberg scissors system. The housing 1 is attached to the reinforcing bars m 15 screws 16, the cassette is installed between the drive horizontal rollers 17, providing rolling channel (roll) 18. Levers; 7 are connected by a hinge 19,

Adjusting the cassette with vertical rollers is done with the following cut

The rotation of the yoke pin 8 and 9: is screwed onto it and move 5 of the auxiliary vertical rolls 6, and the levers 7 of the Nürberg scissors system change their relative position and the hinges 19 move in the rails 12. At the same time, the axes 4 of the main vertical rolls 3 move in the rails 11, the running surfaces 13 and 14 of the guides are diagonally oriented KN and FM of the quadrilateral FKNM. Moreover, any change in the distance b between the main vertical rolls 3 results in the same change in the distance between the auxiliary vertical rolls 6. In addition,

The body vertical rolls 6 are always symmetrically located relative to the main, vertical rolls 3, i.e. . This ensures that all three pairs of rolls are evenly affected by the billet being rolled (channel bar 18), which has a favorable effect on the geometry of the rolled billet.

channel and editing the finished profile. The cassette with vertical rolls works in the image.

Drive horizontal rolls 17 capture the workpiece (channel

roll) 18 and draw it into the fan-roll caliber formed by the working shoulders of the horizontally driven rolls 17 and the main vertical rolls 3. The roll 18 is held on

the entrance and exit of the auxiliary vertical rolls 6, which ensures high stability of the roll 18 and rolling without the undercuts of the shelves, as a result of which subsequent editing of profiles on the correct machine is greatly facilitated.

Claims (1)

Invention Formula A cassette with vertical rolls containing a body, two non-lump plates, a rotation limiter, two main rolls and two auxiliary rolls connected with them by a system of levers placed behind the main rolls on the output side of the cassette, so that To improve the quality of finished steel by reducing the longitudinal stability of the roll, it is equipped with an additional pair of auxiliary rolls placed in front of the main rolls on the input side of the cassette, and the levers are made in the form of a parallelogram system of mechanical mechanisms zmov, binding axes of all rolls, wherein the axes The auxiliary rolls on each side of the cassette are connected by studs with opposite threads at the ends and are fitted with nuts that interact with the studs, and in each the carrier plate is made in four directions, in two of which in each plate are placed with the possibility of reciprocating movement in the vertical plane, perpendicular to the axis of the cassette, the axis of the main rolls, and in the other two - the central hinges of the lever mechanism with the possibility of reciprocating 1terme1 - (ii G, 1OL11 of the cashier axis gee.
