Abstract

The invention relates to rolling production, more precisely to devices for moving, supporting and fixing rolled products, structurally associated with rolling mills. The invention can effectively be used in units with planetary mills. The purpose of the invention is to increase the productivity of the mill. During transshipment, the body 2 is rotated by the hydraulic cylinder 4 around the axis 25. In this case, the drive 13 is located along the axis of rolling. This position of the drive 13 allows it to replace the mill rolls. This shortens the handling time as well as the auxiliary time for the repair and maintenance of the mill, which leads to an increase in productivity. 3 il.

by the camps. The purpose of the invention is to increase the productivity of the mill. During transshipment, the body 2 is rotated by the hydraulic cylinder 4 around the axis 25. In this case, the drive 13 is located along the axis of rolling. This position of the drive 13 allows it to replace the mill rolls. This reduces the transfer time, as well as the auxiliary time for the repair and maintenance of the mill, which leads to an increase in productivity. 3 il.

The invention relates to rolling production, more precisely to devices for moving, supporting and fixing rolled products, structurally associated with rolling mills, and can be effectively used in units with planetary mills.

The purpose of the invention is to increase the productivity of the mill.

Pa figs. 1 shows a device for goma and the transfer of rolled metal from the stand of the planetary mill, general view; in fig. 2 - And in FIG. 1 (enlarged scale, working position), FIG. 3 - the same, the position of transshipment.

The device for receiving and transmitting the rolled stock from the stand of the planetary mill consists of a slab 1, a housing 2 mounted on a slab 1 on bearing supports 3 and can be rotated by an actuator 4. On the housing 2 there are lead wires 5 and 6, non-driven rollers 7-9, mounted on swing arms 10-12, and an additional drive (pneumatic cylinder or G1 cylinder) 13 for handling rolls. The axis of rotation of the housing 2 is parallel to the rolling axis, and the additional drive 13 is mounted so that after rotation of the housing 2 it is located along the rolling axis, i.e. The additional drive 13 is mounted at a distance A from the axis of rotation of the housing 2, equal to the distance from the axis of rotation of the housing 2 to the rolling axis. Wires 5 and 6 are fastened to housing 2 with wings 1A-16. The adjustment of the positions of the rollers 7-9 with respect to the rolling axis is carried out by rotating the rocking levers 10-12 around the axes 17-19 fixed in the housing 2 using adjustable stops 20 and 21 and adjusting pins 22 and 23. The housing 2 is axially fixed by the stop 24 and locking screw 25. In the working position, the housing 2 is fixed

wedges 26 and 27, and in the transshipment position, an adjustable stop 28.

The device works as follows.

The adjustment of the rollers 7-9 relative to the axis of rolling is carried out by adjustable stops 20 and 21, and the stops are placed in such a way that the forces created by the stop screws act in opposite directions, choosing gaps in the synchronization system of the rollers 7-9, thereby reducing their vibration and increasing durability Adjustment of the flatness of the working surfaces of the rollers 7-9 is carried out by the adjustment rods 22 and 23.

The product coming out of the mill rolls over the rollers 7-9, which reduces the amount of resistance to movement, and insures against dropping by wires 5 and 6. In case of an emergency stop of the stand, the product is cut off in front of the front end of wiring 5 and passed on.

When replacing the wires 5 and 6, the covers 14 loosen and fold back, freeing the wires. When reloading the cage or replacing the rolls, the wedges 26 and 27 are knocked out, the housing 2 is driven by an actuator 4 to an adjustable stop 28, freeing the area along the rolling axis before the additional drive 13 .. In this area a device for securing the replaceable working tool (rollers) is placed, connected it is connected to the additional drive 13 and the work rolls are drawn from the stand area. After that, install a new set of work rolls and drive 13 push it into the crate. After the rollers are replaced, the housing 2 is turned by the actuator 4 into the working position and secured with wedges 26 and 27.

The proposed device for receiving and transmitting rolled products from the stand of the planetary mill in comparison with the known ones allows the production of M. Petrov to be increased.
