The invention relates to the processing of metals by pressure, in particular to lines for the manufacture of curved profiles.

The purpose of the invention is the expansion of technological capabilities by providing products such as arch support elements from the original blanks having a bend in the transverse direction.

FIG. 1 shows a flow line for the manufacture of arched elements

a vehicle is installed, for example a trolley 37, on rails 38 with the possibility of reciprocating motion.

Lini works the following way.

The profile bundle on the trolley 37 is brought into the workshop, unloaded on the racks 1, the vibrators 4 are turned on, and from their vibrations the bundle falls into separate rods, which, under the action of vibration

included in the work. In this case, the nozzles 10 enter into the gap between the profiles towards each other and break the whips. The vibration chambers 4 and the springs 5 as racks 1 supports, between the last and the feed roller 6 are installed the guides 7, along which the circular disks 8 move with the disks 8 fixed for 20 displacements along the guides 7 of them hydraulic jacks 9 having wedge disks 8 lightly (if necessary) turn-on nozzles 10 on the rods and working towards each other. The disks 8 have a horizontal drive that is turned on around its axis in order to lift the upper lash of the profile and carry the lash to the roller table 6, where the disks 8 once again rotate around the axis and reset the ability to rotate around its axis (the rotation drive is not shown). Between they begin around their axis in order to lift the upper lash of the profile and carry the lash to the roller table 6, where the disks 8 once again turn around the axis and drop the profile, turn off the straightening rollers and turn on the press 15 of the wheelhouse. At the same time, the resulting reaction forces are extinguished by the damper 14 and do not transfer to the rollers 13 by the guides 7 the drive mechanism is placed from the nozzles 10 of the whip to the live rolls 6.

base 11, for example, chains 12. A low whip is fed to the roller chain. The roller conveyor 6 is installed along the length 12. The roller conveyor 6 delivers the profile to the rihosi line and is connected to the straightening rollers 13, which are rihted by the probes 13, which through the damping film and immediately free

mechanism 14 is connected to the press 15 rub. ,,, end served under the press 15. ki profile. Behind the press 15 is installed a photometal based on a predetermined size of an otmerolang 16 with sliding adjustable rollers 17, with a photo relay 18 against them and a lateral inclined chute 19. The roller conveyor 16 is connected with the roller conveyor 20, feeding the profile into bending rollers 21, producing -cc with. If the workpiece is dimensional, then bending of the workpieces in a vertical plane is given further by the roller tables 16 and 20 along the axis of the line with the possibility of turning-bending rollers 21. If this is the remainder or

The aerating machine is installed at the point 25, the bending rolls 21 are adjusted to

the receiving frame 22 is made in the form of a lodge, concave in at 25, with rollers 26 between two sidewalls 27, divorced from above.

A tilted plane 29, adjacent to a line on the same side as rack 1, is connected to the auxiller bed 28 on the same side as rack 1. With the inclined plane 29, a drive 31 of the containers 32 is connected by means of the guides 30. The latter pushed back to its original position. pushed onto an inclined plane. The workpiece slides along an inclined 29 by pushers 33. On an inclined plane 29 on both sides of the guides 30 are uprights 34 (Fig. 5), on which the pushers 35 (for example, electromagnetic) are fixed, alternately bottom-up 55 pushing intermediate pads 36 in containers 32 Parallel to the entire line from the side of the rack 1

any radius of the workpieces are flexible, bend the workpiece and give it out in the plane of the line upwards, from where it falls on the frame 22 under the action of its own weight. In view of the fact that the sidewalls 27 in the upper part are separated, the workpiece falls on the rollers 26 and is centered in the receiving frame 22, as it is curved to the bottom. The actuator 24 is turned on and the frame 22 is tilted, and

plane 29 and enters container 32, which is pre-pushed by 33 along guide rails 30 on plane 29.

After placing the arch support in the container of the first element (Fig. 5), electromagnetic pushers 35 are pushed on the uprights 34 and push the gaskets 36 over the installed vehicle, for example, the trolley 37, on the rails 38 with the possibility of reciprocating motion.

Lini works the following way.

The profile bundle on the trolley 37 is brought into the workshop, unloaded on the racks 1, the vibrators 4 are turned on, and from their vibrations the bundle falls into separate rods, which, under the action of vibration

This includes driving the horizontal movement of the disks 8 along the guides 7, the disks 8 slightly (if necessary) turning

are mounted around their axis in order to raise the upper lash of the profile and carry the lash to the roller table 6, where the disks 8 once again turn around the axis and drop 10 lash from the nozzles into the roller table 6.

Rt profile, turns off the leveling rollers and includes press 15 cuttings. At the same time, the reaction forces arising are quenched by the damper 14 and do not transfer the end to the rollers 13 under the press 15. The photo relay according to the specified dimensions of the mixture If the workpiece is dimensional, then it is delivered further by the live rolls 16 and 20 to the bending rolls 21. If this is the remainder or

any radius of the workpieces are flexible, bend the workpiece and give it out in the plane of the line upwards, from where it falls on the frame 22 under the action of its own weight. In view of the fact that the sidewalls 27 in the upper part are separated, the workpiece falls on the rollers 26 and is centered in the receiving frame 22, as it is curved to the bottom. The actuator 24 is turned on and the frame 22 is tilted, and

plane 29 and enters container 32, which is pre-pushed by 33 along guide rails 30 on plane 29.

After placing the arch support in the container of the first element (Fig. 5), the electromagnetic pushers 35 are inserted on the uprights 34 and push the gaskets 36 over the laid element so that the next element lies on the gaskets. This operation is repeated until the container 32 is filled. The loaded containers are removed and the trolley 37 is taken out for storage.

The application of the invention allows to significantly increase productivity, reduce heavy manual labor for the separation of profiles, feeding them under the press,

warehousing, wrapping of finished elements Yu installed behind the cutting device and lining, their delivery to the mine and the section-made in the form of a photo relay and rollers,
