i

Tilters of rolled products are known that contain rollers for holding rolled products against anti-rim faces, hydro-dilution of dilution and rolling of rollers, turning rollers and rotation of their rollers.

The proposed tilter for renting is characterized by the fact that it is mounted on one of the rulers of the manipulator, each of its edging rollers is freely mounted on a bent knot angle of the axle of the edging shaft, and the drive shaft is made in the form of a planetary gear.

This makes it possible to simultaneously turn the product over and move it in the longitudinal direction.

FIG. 1 shows the proposed tilter, a plan view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 2; in fig. 4 shows a section along BB in FIG. 3; in fig. 5 is a section along the GGD of FIG. 3

At the working stand 1 of the rolling mill with rollers 2 above the live rolls 3, the manipulator lines 4 are installed, which combine the longitudinal axis of the rolled products 5 with a caliber of 6 on the rolls 2.

The tilter of the rental 7 is mounted on one of the ruler lines of the manipulator 4 and consists of two rollers 8 which are freely mounted on two beveling shafts 9. The end trunnion 9 of the knitting shaft is used for 2

The cage of the roller 8 is directed at an angle, preferably at 45 °, to the main part of the shaft, and at its opposite end 9 the bevel gear 10 is fixed, which engages with the bevel gear And, which is fixedly mounted on the shaft 12.

 of the two shafts 12 is the axis of the hinge, around which the movable body 15 can swing on the bearings 13 and 14 (see Fig. 4), and inside the latter, on the bends 16 and 17 (see Fig. 5), the rotating shaft 9 is mounted the end trunnion 9 and the adjacent curved section of the beveling shaft are installed outside the movable body 15.

Both shafts 12 with gears 12 are, moreover, mat.; 1, one common planetary gear train in which two gears 121 can run around stationary central gear 18. Gears 12 with shafts 12 are mounted on subshell 19 and 20 in housing 21 drove, which is installed on two bearings 22.

Claims (2)

The base bracket 23 bearing the bearings 22 is fixedly mounted on one of the ruler lines of the manipulator 4. The central gear 18, which is in engagement with two gears of the satellite gears 12, is fixedly mounted on the shaft 24, which is mounted in the housing 21 on the bearings 25, its axis is aligned with the axis of rotation of the carrier body 21, and the shaft 24 itself is secured by turning the nuts 26, the washers 27 and the cover 28 from turning with a nomoil (see Fig. 4). A hydraulic cylinder 29 is mounted on the base bracket 23, which by its rod 30 (see Fig. 3} is connected to the carrier housing 21, provides a 90 ° rotation and return to the initial position. The other power cylinder 31 is connected to one of the movable housings 15, and its rod 32 is also connected to the second movable body 15, providing a reduction and dilution of the kaputyush, their rollers 8 by rocking the movable housings around the shafts 12 in bearings 13 and 14. One of the movable housings 15 is equipped with a support roller, which when lowered .mobile body up It is installed in a rail installed to limit the edge of its lower nanting rollers 8 and provide the necessary polishing of the transported rolling levels 5 and the levels of possible positions of the rolling rollers 8. The rolling tilter works as follows: In the initial position, using a power cylinder 31 swiveling rollers 8 maximally diluted, with the atom the lower roller is lowered below the level of the roller table 3, the upper one is raised above the roller table for free passage of the rolled product transported along the roller table. The marked position of the lower bending roller 8 is determined by the selection of an appropriate rail mounting level on which the support roller is placed in the initial position. Accordingly, the position of the upper bending roller is determined by the stroke value of the rod 32 of the power cylinder 31. At the approach of hire 5 along the roll table 3 to the turner 7 and the need for turning the power cylinder 31 switches to converging the turning shafts 9, which leads to rotation of the movable housings 15 towards each other and according to the note of the turning rollers 8 for clamping opposite edges of the cross-section of the rolled product 5. After this, the power cylinder 29 is turned on, which rotates the housing 90 21 of the carrier 21 by 90 то. Rotation of the body of the carrier entails running around the gears - satellites 12 of the stationary central gear 18, the diameter and number of teeth of which are twice as large respectively as the diameter and the number of teeth of each of the gears satellite The rotation of the gears of the planetary gears drove 21 by 90 ° causes the satellites to rotate by 180 °. This rotation through a bevel gear 11-10 with a ratio of 1: 1 is associated with the turning shafts 9, which also rotate 180 °. Simultaneously with the rotation of 180 °, the bending shafts 9 make, together with the movable bodies 15, an opposing longitudinal movement due to the hinged connection of the movable bodies 15 with the body 21 of the carrier turning 90 °. The fact that the edging roller 8 is directed with respect to the longitudinal axis of the rolling shaft 9 at an angle of 45 °, the turning of the rotating rollers by .180 ° in combination with their longitudinal movement ensures tilting of rolled 5 by 90 ° sandwiched between the rollers 8. After this, the cut-off cylinder 31 switches to pushing out the rod 32, the bending rollers are diluted, the tilter takes up its original position and is ready to execute the next working operation in the sequence described above. Claim 1. A tilting machine containing rollers to hold the rolling along opposite edges, a hydraulic cylinder for spreading and rolling rollers, rotating shafts and driving them to rotate is different from the fact that, for the purpose of simultaneous rotation and longitudinal movement of the rolled metal, each turning the roller is freely mounted on the angled shaft bent at an angle. 2. The tiller according to claim 1, characterized in that, in order to reduce overall dimensions, the rotational drive and the longitudinal movement of the beveling shafts are made in the form of a planetary gear.
