Description

The utility model relates to the field of rolling production and can be used for the transverse transfer of long and sheet products between parallel live rolls.

A device is known for moving rolled products (RF Patent No. 45315, M. class B 21 B 39/00, published May 10, 2005), consisting of parallel live rolls and a rental transfer mechanism between them, containing rods with a rack and pinion drive for their horizontal movement located between the roller tables, and transporting rulers, pairwise connecting the ends of the rods, equipped with rollers installed with the possibility of longitudinal movement in profile guides, fixed between the rollers of the roller tables along the entire length of the stroke of the rods. Between the rollers, guides are provided with support rollers.

A disadvantage of the known device is that the movement of the rolled products, carried out by the rulers, is dragged with sliding on the rollers of the roller tables, which causes deformation and damage to the rubbing surfaces of both the rollers and the rolled products.

The closest to the proposed technical solution for the purpose, design and technical result achieved is a device for moving rolled products between parallel live rolls (Patent RU No. 56229 dated 03/10/2006 IPC V 21 V 39/00), containing a mechanism for transferring rolled products from one live roll on the other, a rack-and-pinion drive of its movement, including a rotary shaft with gears, located between the parallel roller tables, a mechanism for raising and lowering the rental, consisting of parallel rows of rotary two-arm levers installed along the entire length of the movement of the rental,

whose lower shoulders are interconnected by rods and with a common lever mechanism for their rotation, equipped with a hydraulic drive.

The disadvantage of the considered device is that regardless of the length and quantity of the rental, its movement is carried out by the operation of the entire mechanism, which significantly slows down the transfer process, reduces the rolling performance in general,

The objective of the utility model is to expand the technological capabilities of the device and increase the productivity of the rolling section as a whole.

To achieve this goal, in a device for moving rolled products between parallel live rolls, containing a mechanism for transferring rolled products from one live roll to another, a rack-and-pinion drive for moving it, including a rotary shaft with gears located between parallel live rolls, a lifting and lowering mechanism for rolling, consisting of parallel rows of rotary two shoulders levers installed along the entire length of the rolling stock, the lower shoulders of which are connected by rods to each other, the gear transmission mechanism is made in the form of a parallel t-beams with toothed rails and guides in the lower part, the upper shoulders of the rotary two-arm levers are equipped with rollers with flanges, while the T-beams are mounted with the possibility of longitudinal movement between the rollers of the live rolls with a rack-and-pinion drive for moving along the rollers of the two-arm levers, and the adjacent rows of rotary two-arm levers are combined into sections of two or more, each section is equipped with an individual drive for raising and lowering it.

Due to the presence of these signs, the technological capabilities of the device are expanded and the productivity of the rolling process as a whole is improved.

The proposed device for moving rolled products between parallel roller tables is shown in the drawings.

Figure 1 shows a General view of the device in plan;

Figure 2 is a section aa of figure 1;

Figure 3 is a section bB of figure 2;

Figure 4 is a section bb In figure 2.

A device for moving rolled products between parallel live rolls contains live rolls 1, 2, a mechanism for transferring rolled products from one live roll to another, including parallel T-beams 3 with guides 4 and with gear racks 5, mounted with the possibility of longitudinal movement between the rollers of live rolls 1, 2, a lifting mechanism and lowering the T-beams 3, consisting of parallel rows of rotary two-arm levers 6, sequentially installed under each T-beam 3 for the entire length of its stroke, the lower shoulders of which are connected by rods and 7 with each other and with the levers 8 of the drive of their rotation, as well as the rack drive 9 of the longitudinal movement of the T-beams 3, located between the parallel roller tables 1, 2, including the drive gear shaft 10, interconnected by gear couplings 11 and interacting with the gear racks 5 T-beams 3 through the intermediate gears 12 mounted with the possibility of free rotation on the upper shoulders of the central rotary levers 13 of each row. The upper shoulders of the rotary two-arm levers 6 are equipped with rollers 14 with flanges interacting with the guides 4 of the T-beams 3 mounted on both sides of the gear racks 5, while the adjacent rows of the rotary two-arm levers 6 are combined in sections of two or more and each section is equipped with an individual drive 15 its raising and lowering.

The operation of the device is as follows. In the initial position, the rotary two-arm levers 6 are in the lower position, the parallel T-beams 3 with the guides 4 are lowered below the level of the rollers of the roller tables 1 and 2. Rolled through one of the roller tables to be transferred to the other roller table, it stops in the area of operation of the rolling gear one live roll on another. Depending on the

the length of the rental, one or more sections of parallel T-beams 3 with guides 4 rise to the upper position, raise the rental above the roller table and transfer it for laying on a parallel roller table. T-beams 3 not involved sections of the device while moving under the level of the roller table. After stopping at the required position, the raised sections of the T-beams 3 with the guides 4 are lowered to the lower position, the device returns to its original position.

Using a device for moving rolled products between parallel rolling tables of the proposed design will increase the productivity of the rolling section by 1.5-2 times, depending on the product mix.
