Description

one

The invention relates to the equipment for finishing and laying sections of predominantly section mills and can be used for turning 180 packs of thin-walled sections with a wide height range.

The purpose of the invention is the elimination of rolling deformation during turning.

FIG. 1 shows a tilter plan view; in fig. 2 shows section A-A in FIG. 1 (cross section of the turner in the initial position for turning); in FIG. 3, the node J in FIG. 2 (view of lowering and raising levers); in fig. 4 is a section BB in FIG. 1 (turner drive); in fig. 5 shows a section B-B in FIG. 3 (mounting on the lowering arm pipes and stops); in fig. 6 is a section of the Gn of FIG. 3 (stop device); in fig. 7-11 - diagrams of the positions of the tilting elements, explaining his work.

Tilter rental contains a number of lifts 1 and a number of lowering 2 rental levers mounted on the same axis 3 on the support in the housing 4. Each lowering lever is equipped with a sponge 5, spring-loaded relative to the lever elements 6, and stops 7 on the shock absorbers 8. The lifting levers are equipped protrusions 9.

The tilter has two transmission shafts 10 and I, with which the levers of the same name are connected by means of levers 12 and 13 and t g 14 and 15.

The transmission shafts, by means of the drive levers 16 and 17, are connected to the hydraulic cylinders 18 and 19. The latter ensure the rotation of the bending arms relative to their common axis. The rental is supplied to the tilter and diverted from it by the transport device 20.

Tilter works as follows.

Starting position before turning over (Fig. 7). The protrusions of the 9 lifting levers 1 raise the top of the working position of the transport device 20 (for example, a chain spreader).

Rental, intended for turning, is moved by the transport device up to the stop in the protrusions 9. Thereafter, the lowering levers 2 are moved by the hydraulic cylinder 18 in

their extreme left position and give a signal at the beginning of the movement of the lifting-levers (Fig. 8). .

The lifting levers remove the pro 5 cat from the transport device and, continuing their movement, press it to the jaws 5, compress the springs of the elements 6, and close the system of operating levers, affecting the stops 7 10 of the lowering levers. The hydraulic cylinder 19, having overworked the hydraulic cylinder 18, has relocated the entire system with the clamped pro-. volume to the extreme right position of the lift arms (Fig. 9).

After this, the lowering levers (Fig. U) are moved to the initial position, and then the lifting arms, while the lowering levers place the skantovanny rolled steel on the transport device. The protrusions 9 may be lowered below the level of the vehicle for transporting rolled products without turning (Fig. 1).

The proposed tilter of the single-layer package ensures reliable retention of flange rolled products on the beaming arms without spilling the bag in a wide range of high-grade rolled steel. At the base object, the height range of the flange profiles that can be turned on is very limited. This is due to the fact that flange rolling, as a rule, when turning up is in contact with the working surface of the electromagnet with ribs (for example, the edges of the shelves of channels and I-beams). The main mass of the profile is located at some distance from the electromagnet, i.e. there is an air gap between it and the working surface of the electromagnet. The magnitude of the magnetic force of attraction of a rolled metal to the working surface of an electromagnet depends on the size of the air gap between them. Moreover, the larger the gap, i.e. the higher the ribs (flanks), the stronger the weakening of the force of attraction.

In addition, the weight of the turning arms is reduced, which influences the weight of all other elements of the turning device, which reduces the metal intensity of the turning device as a whole; it also saves electrical equipment, copper and electricity. The efficiency of the tilter is achieved, and its maintenance during operation is simplified.
