专利说明:

The invention relates to rolling production, namely, universal dual-use stands for rolling mills, used as double-roll stands, as well as a device for replacing the rolls of universal stands and two-roll stands of rolling mills.
The purpose of the invention is to simplify and reduce the cost of construction.
Figure 1 shows the proposed stand, the layout of the equipment, a general view, in Figure 2 - the same, a front view; fig.Z - the same, side view; 4 and 5 show the cage, respectively, in the form of a two-roll or universal cage, respectively; figure 6 - twin roll stand disassembled; 7 is a universal stand in a disassembled
the form; Fig. 3 shows the installation of vertical and horizontal rolls in the universal stand; Fig. 9 is a diagram of installation of equipment fixing means.
The twin roll stand 1 and universal stand 2 are made in the form of support blocks 3, including the base 4, pressure screws 5 for adjusting the gauge of the rolls, thereby forming the first block 6 mounted on the base plate 7.
The first block 6, together with the third block 8 with the vertical rolls 9, forms the second block 10, which is the only block assembled into a single whole, which is used to form the components of a two-roll stand

with
or universal rolling mill stand.
The differences in the designs of twin-roll and universal stands relate to the execution of horizontal rolls 11 and 12, respectively, of the fourth block 13 and the fifth block 14 with vertical rolls.
The fourth unit 13 contains the rollers 11 and the wire reinforcement 15 for holding the equipment, while the fifth unit 16 includes the rolls 12 of the universal stand, the wire reinforcement 17 of the universal stand for holding the equipment and the third block 8 including vertical mill rolls 9.
The wire fittings 15 and 17, respectively, of the two-roll stand and the universal stand are attached to the beds 4 by mounting the rods 18 into the receiving openings 19 of the beds and fixing them with forked clamps 20 made in the form of forks, which are inserted into the peripheral grooves 21 formed on the rods 18 by machining.
Beds 4 are made with outer protrusions 22, which have two grooves 23 and 24. The latter interact with the hydraulic clamping ring 25, fixing the protrusions 22 to the stand 26, thereby ensuring the location of the pre-mounted unit or stands according to its functioning - as a double-roll or universal stand rolling mill.
Beds 4 are also made with internal protrusions 27, the support surfaces 28 of which are intended for lateral arrangement of third blocks 8 with vertical rolling rollers.
The rods 29 of the universal stand cooperate with the internal projections 27 and secure the vertical rolls with clamps 20. The internal projections 27 also contain means for fastening the pressure screws 5, which cooperate with the respective beds 4. The pressure screws 5 are connected by means of an adjusting unit, the projections 22 mainly located near the vertical axis of the bed 4.
Racks 26 are arranged in pairs on frames 30, which are located on the female beam 31. Racks 26 may be stationary or movable. The beam 31 together with the frames 30 and the uprights 26 forms the base plate 7.
The device 32 for replacing the rolls of the proposed stand comprises a base 33, in
The center of which is equipped with a platform-table 34, which is a turntable, with means for holding the stand 1 with containers 35, designed to hold the horizontal rolls 11 of the two-roll stand.
The containers 35 correspond to the geometrical characteristics of the rolls 11 and use the bar 36 installed with
0 is able to move between guide rollers 37 designed to hold the upper roll 12 of the universal stand while the lower roll rests on the corresponding lower 5 surface 38. The side surfaces 39 allow proper alignment of the rolls 11 and 12.
Cage .1 (Figures 2 and 5) is a universal stand of a rolling mill or
0 two-roll stand of the rolling mill (fig.Z and 4). In this embodiment, the turntable 34 has a first post 40 for replacing the rollers 11 and a second post 41 for loading and unloading the stands 42.
5 Two movable supports 43 are mounted
together with the second station 41 on the same axis as the rolls 11 and 12 included here. These movable supports 43 can move along the axis of the rolls 11 and 12.
0 Fixed pillars 44 are located on both sides of the base 45 at its ends at the end of the course of movement of each mobile support 43. The latter are equipped with racks 46, which contain hydraulic
5 clamping rings 47 serving to clamp the second unit 10 and the first unit 61 in the slots 23 and 24.
The movable supports 43 have the position of the closest mutual approach, which corresponds to the position of the beam 31.
On the turntable 34 there are roll containers 35 that serve to accommodate the rolls 11 and 12 and the wiring reinforcement 15 and 17 with the help of fingers 48 and
5 support surfaces 49.
When it is necessary to re-equip the universal stand 2 into the two-roll stand 1 of the rolling mill, the container for the rolls of the universal rolling stand
The mill 0 is located at the second station 41, while the roll roll container for the two-roll stand of the rolling mill is located at the first station 40.
5 The two-roll stand roll containers at the first station 40 are provided in advance with appropriate wiring reinforcement 15 for holding the equipment, a table for the equipment, equipment and rolling rollers 11 and 12, all of which are set in advance and adjusted to the required values at the first station 40.
When the cage 2 is moved (fig. 3) to the second station 41, it interacts with the corresponding roll container and allows the components of this particular cage to be precisely positioned.
When the stand 2 is located at the second station 41, it is located on the uprights 46 and clamped by hydraulic clamping rings 47.
By removing the clamps 20, it is possible to displace the movable supports 43, which move the second unit 10. The third unit 8, including the vertical rolls, also moves with the second unit 10.
This third block 8 is moved by a second block 10 to a fixed rack 44, where hydraulic clamps 50 secure the third block 8 and allow it to be disconnected from the second block 10 by removing clamps 20 that are attached to rods 29 of a universal stand rigidly attached to the frame four.
The work is carried out in a similar way when it is necessary to transform a two-roll stand 1 into a universal stand 2 of a rolling mill, the third, node 8 is pre-positioned on a fixed stand 44 and is taken up by a movable support 43, which moves the first node 6. T the driving device 51 serves to move the movable supports 43.
The advantages of the invention in comparison with the known solution are that it allows to simplify maintenance, standardize components and parts, reduce maintenance time, use smaller areas, pre-adjust and adjust roll gauges.
