The invention relates to devices for the manufacture of a non-rotating helix of unlimited length and can be used in the cable, engineering and other industries, as well as in the oil and gas industry for the manufacture of flexible reinforced pipes.

The purpose of the invention is the expansion of those-jg Then with the help of an adjusting wine

capabilities by preparing a helix from a tape with engagement of turns.

FIG. 1 shows a general scheme of the device; in fig. 2 is a view A of FIG. one; in fig. 3 shows a kinematic diagram of the mechanisms for shaping and closing the helix forming and feeding the tape.

The proposed device consists of a frame 1, on which a hollow shaft 2 is mounted on rolling bearings, with a drive 3 of a mechanism 4 for feeding a tape of a section, a platen 5. On a plate there is a drum 6 with a tape 4 that is fixed on a cantilever tube 7 on rolling bearings the tape feed mechanism 8, the shaping mechanism 9 by profiling semi-matrix rollers 10, the shaping and closing mechanism 11 of the helix with the guide-clamping rollers 12 o

The forming mechanism 9 is fixed on the faceplate 5 and contains profiling semi-matrix rollers 10 (3-5 pairs), kinematically connected to the electric motor 15 by means of gears 16-25-26 of the feed mechanism and belt drive.

The mechanism 11 for shaping and closing the helix is fixed on the faceplate 5 and contains a half-length of the roller-roller 12 of a given configuration for the gradual closing of the helix, kinematically connected with the electric motor

This tension of the roller chain creates a gap between the groove of the feed roller.

13 and a chain 14. The end of the winding tape 4 wound on the drum 6 is passed into the resulting gap between the chain 14 and the feed roller 13 of the feed mechanism B, the profiling semi-matrix rollers 10 of the forming mechanism 9 in the direction-contraction rollers 12 of the spiral forming and closing mechanism 14.

Rotating the faceplate 5 manually, two or three turns of the spiral with the engagement of the turns form. After that, using the adjusting screw, create the necessary force to press the roller chain 14 to the chute of the feed roller 13. The electric motor 15 is turned on and the further operation takes place automatically. From the electric motor 15, through a belt drive, rotation is transmitted to the shaft 2 and through gears 24-16, to the shaft of the feed roller 13 of the feed mechanism 8. Replaceable gears are designed to adjust the device when changing the diameter of the spiral.

The roller 13 of the feeder mechanism 8, while rotating, winds the winding tape 4 from the drum 6 and delivers it forcibly by friction between the feed roller 13 and the roller chain.

14in the feed mechanism 8. Then, the winding tape 4 is fed to the profiling semi-matrix rollers 10 of mechanism 9, where it is given due to compression and friction forces arising from the forced rotation of the rollers 10, a configuration is necessary. The profiled belt 4 t is drawn by the caster rollers of the forming mechanism 9 into the spiral forming and closing mechanism 11, where it is deformed into a non-rotating spiral with a coil engagement. The closure of the helix occurs by crimping from the profiled locks of the tape guide-squeezing rollers 12.

Nevrashagoscha with a spiral of unlimited length with the engagement of the coils. It is formed by the opposite rotation with the same angular speed of winding the spiral and faceplate.

The proposed device makes it possible to obtain a spiral of unlimited length with an engagement of turns, which makes it possible to manufacture durable flexible pipes, umbilicals used in various sectors of the national economy.
