The presence of a belt transmission of torque from the electric motor to the gearbox leads to inertia of free travel, which complicates the work when curling, because it is necessary to turn off the motor in advance so that the curling stops in the right place, otherwise the part will bend and a blank with an undefined configuration is formed.

The inventive device, in contrast to the analogue, contains one forge-press unit, in addition, the pipe preparation unit has only two solid working shafts, the third serves only to transmit torque from the gearbox to the two working shafts.

In the inventive device, the parallel indentation of two opposite walls of the profile pipe with a small depression in the center provides the preparation of the profile pipe with different wall thicknesses for further uniform screwless screwing into a spiral, the working shafts are upper, middle, lower one-piece so that their distance between the axes is always rolled pipes are obtained in the same shape for a very long time of operation. Also, on these shafts, by shifting the center, an eccentric part is machined, consisting of two working surfaces, on one of which there are volume grooves for obtaining a volumetric pattern at the ends of the heated steel, the second surface is made smooth - flat for squeezing the ends on cold rolled profile pipes and at the warmed ends of the car.

The lack of belt transmission of torque from the electric motor to the gearbox does not lead to inertia of free wheeling, which leads to marriage in operation.

A device for obtaining a decorative relief on the surface of the blanks from the patent for utility model RU 122922, IPC, B21D 17/04, from 11.01.2012, publ. 12.20.2012, comprising a bed with a casing and a table, an electric drive with a control system, an intermediate and working gears, a guide, an emphasis, characterized in that the working gear is made with two cantilever working shafts, on which work rolls are located with the possibility of replacement to compress the surface blanks.

Disadvantages: increased inertia of free play.

The presence of a belt transmission of torque from the electric motor to the gearbox leads to inertia of free travel, which complicates the work when curling, because it is necessary to turn off the motor in advance so that the curling stops in the right place, otherwise the part will bend and a blank with an undefined configuration is formed.

EFFECT: reduced inertia of the free run, which leads to an increase in the accuracy of profiling when curling the workpiece into a spiral.

The technical result in a forging device containing a bed, gear motors connected to an electric motor, an electric drive with a control system, three horizontal working shafts located one above the other, connected by a gear kinematic transmission, two of which have an eccentric part, a faceplate, two templates, made with the possibility of their replacement on the faceplate, and fixed on the base stop, is achieved due to the fact that the control system of the electric motor is made in the form of two loose left on the bed of pedal buttons, the first of which is used to start the electric motor, the torque of which is transmitted through the shaft with the key to the geared motor for curling spirals clockwise, and the second - to start the electric motor counterclockwise, each working shaft with an eccentric part made integrally, has at least three grooves for creating a decorative relief, drawing risks in the center of the pressed surface on profile pipes of different sizes, the eccentric part consisting of two working parts surfaces, one of which has three-dimensional grooves for creating a three-dimensional pattern, and the other is flat for squeezing the ends of the workpieces, each template made with a disk for replacing it on the faceplate has a groove with a semicircular hole and a semicircular clip to capture the workpiece, and one template is made one-level and the other two-level with an angle of rotation of at least 350 °, consisting of upper and lower parts, fastened together, while the two-level emphasis is made adjustable with the ability to move along the milled the bore of the base.

The specified number of grooves provide rental pipes of three sizes. In the inventive device, the torque from the electric motor is transmitted through its shaft with a key to the gear motor, and not through a belt drive. This made it possible to significantly reduce the inertia of the electric motor after turning off its power, and this, in turn, facilitates the process of repeatability of curling spirals without defects, with high profiling accuracy when curling a workpiece into a spiral. The indicated number of grooves is used taking into account the often used sizes of profile pipes to obtain a decorative relief on them. Drawing risks in the center of the pressed surface is necessary for the correct folding and twisting of the profile pipe in a spiral.

The upper part of the two-level stop is made smaller in diameter relative to its lower part, this is due to the need to divide the working surface to create a protrusion on it, on which the unclamped end of the workpiece is placed, when curling, around the upper part of the two-level template. This protrusion is in the same plane with the top of the bottom of the two-level template. When curling a spiral around a single-level template, the upper part of the stop is not used, and curling is done by lowering the workpiece onto the template disk, relative to the lower part of the two-level stop.

The essence of the proposed technical solution is illustrated by an example of a specific design and drawings, which show:

in FIG. 1 is a top view of the device;

in FIG. 2 is a side view of the left side of the device;

in FIG. 3 is a front view of the device;

in FIG. 4 is a view of the working shafts of the pipe preparation unit;

in FIG. 5 is a view of a single-level template;

in FIG. 6 is a view of a two-level template.

The rolling-bending device comprises a frame 17, on which are fixed: an electric motor 1 with a control system from the first pedal button 18, the second pedal button 19 and the electric box 16, a gear motor for curling spirals 3 connected to a gear motor 2 for transmission torque through the connection set of two gears 4 to the gear motor 3 for curling spirals on the one hand, and to the pipe preparation unit 5 on the other. The pipe preparation unit 5 consists of three horizontal shafts - the upper working shaft of block 6, the middle working shaft of block 7, the lower shaft 8. The shafts 6, 7 with the eccentric part are made integral and rotate towards each other, receiving torque from the lower shaft 8, they located one above the other, connected by a gear kinematic transmission. The distance between the axes of the shafts 6, 7, 8 is unchanged, which ensures accurate and reliable repeatability of rolled profile pipes over a long time of operation. Each working shaft 6, 7 has at least three grooves for creating not only a decorative relief on different sized profile pipes, but also drawing risks in the center of the pressed surface. To obtain a decorative relief on profile pipes, the specified number of grooves allows the rental of pipes of the three most commonly used sizes.

Two foot pedal buttons 18, 19 are not fixed on the bed, provide reverse start of electric motor 1. The first pedal button 18 is used to start electric motor 1, the torque of which is transmitted through a shaft with a key, pressed into motor gearbox 2 to the gearmotor for curling spirals 3 clockwise. The second pedal button 19 is used to start the electric motor 1 and rotate the gear motor for curling the spirals 3 counterclockwise.

The upper working shaft 6 of the pipe preparation unit 5 and the middle working shaft 7 are designed for rolling profile pipes of various sections, to create not only a decorative relief on them, but also to apply risks to the center of the pressed surface, according to which the profile pipe will later be correctly folded and twisted into a spiral, as well as for squeezing the ends of profile pipes. By heating the ends of corpulent billets of round or square cross-section using the upper working shaft 6 of block 5 and the middle working shaft 7, you can get a three-dimensional picture in the form of a “goose foot ″.

The geared motor for curling spirals 3 is designed to rotate the drive shaft of the faceplate 9, to which the faceplate 10 is welded. There are two threaded holes on the faceplate 10 for quick replacement of the same diameter disks with templates 11, 12. Various types of fixed disks are fixed on these disks templates 11, 12, around which prepared blanks are curled. Pattern 11 is made in height in one level. Template 12 is made in height in two levels and consists of upper and lower parts. Each template has a semicircular hole for turning it in a semicircular clamp clockwise to clamp the end of the workpiece. Curling of the workpiece occurs relative to the adjustable stop 13, which is held down by a clamping bolt 14 to the base for the stop 15. At the base for the stop 15 there is a groove along which the stop 13 moves to adjust the curling of the length of the spiral.

The upper part of the two-level stop 13 is smaller in diameter relative to its lower part, this leads to the separation of the working surface to create a protrusion on it, on which the unclamped end of the workpiece is placed, while curling, around the upper part of the two-level template 12. This protrusion is in the same plane with the top bottom of the two-level template 12.

The inventive device has a simple design that does not require any adjustments, performs a large number of technological operations with small dimensions with high quality and repeatability of curled spirals.

The inventive device operates as follows.

To reproduce torque, turn on the electric motor 1 with a rotation speed of 3000 rpm. The torque is transmitted from the shaft of the electric motor 1 to the gear motor 2, then from the gear motor 2 it diverges on two sides, while rotating the gear motor shaft for curling the spiral 3, and the lower shaft 8 of the pipe preparation unit 5. On one side of the lower shaft 8 torque, through a gear drive sets in motion two solid working shafts 6, 7, they rotate towards each other, washing two opposite walls of the profile pipe at the same time, then the end of the rolled pipe is flattened on the eccentric part of the same s. On the other hand, the geared motor for curling spiral 3, through the connection set of two gears 4, lowers the number of revolutions of torque and transfers them through the drive shaft of the faceplate 9 to the faceplate 10.

The washer 10 with one of the templates 11, or 12, fixed with two bolts, rotating clockwise, curls the workpiece relative to the adjustable stop 13, which is attached to the base for the stop 15 by a pressure bolt 14.

The emphasis 13 moves in the base for the emphasis 15 along the milled hole. A two-level template 12, made in height in two levels, is rotated by an angle of more than 350 degrees, overlapping with its end the groove for clamping the workpiece (Fig. 6). The prepared profile pipe is inserted into a special groove in the upper part of the two-level template 12, and clamped with a semicircular clamp when turning clockwise in a semicircular hole. The remaining, non-clamped part of the workpiece is brought to the upper part of the stop 13 by briefly pressing the foot pedal button 18, which, through the electric box 16, supplies power to the electric motor 1. Checking visually that the workpiece clamped in the upper part of the two-level template 12 lies on the lower part of this template 12 and the protrusion of the stop 13, begin to curl it in a spiral by pressing the first pedal button 18. Curling occurs clockwise until the bottom of the two-level template 12 comes out from under the workpiece, then releasing the first pedal button 18 and briefly pressing the second pedal button 19 release the curled part. Further, if it is necessary to continue curling in a spiral, the workpiece is lowered below, onto a disk screwed to the faceplate 10 with two bolts, to which a two-level template 12 is fixed, again pressing the first pedal button 18 activates the whole mechanism mounted on the bed 17, and the workpiece continues to curl around the lower part of the two-level template 12. At this time, the free end of the workpiece rests on the lower part of the stop 13. Having circled the lower part of the two-level template 12 around the workpiece, release the first pedal button 18. To remove Nia curled into a spiral blank is pressed the second button pedal 19. Duplex pattern 12 is scrolled in the opposite direction, releasing tension from a preform after which it is easily removed from Template 12 bilevel.

When curling a spiral around a single-level template 11, the upper part of the stop 13 is not used, and curling is done by lowering the workpiece onto the disk of the template 11, relative to the lower part of the two-level stop 13.

If it is necessary to obtain a different shape of the spiral, the disk fastened with two bolts on the faceplate 10 is quickly removed, the template 11 or 12 is changed, as a result of this, the machine is reconfigured for curling another type of spiral.

The use of the claimed utility model will provide a decrease in the inertia of the freewheel, which will lead to an increase in the profiling accuracy when curling the workpiece into a spiral.
