Description

The invention relates to machines for winding wire spirals onto a pipe using a rotating mandrel with a screw thread and a roll wire that is rotating around the mandrel.

In the proposed machine, to secure the turns of the wound wire around the circumference of the tube, the mandrel serving for winding the wire is hollow and the clamping wire running around the tube between said turns passes through it.

In the drawing of FIG. 1, a schematic diagram of a machine for winding wire spirals onto a pipe; FIG. 2 is a front view of the means for communicating the pipe to translational motion; Fig, 3 is a side view of it; FIG. 4 - view from below; FIG. 5 is a longitudinal section of the head with a roller; FIG. 6 is a view along arrow A of FIG. five; FIG. 7 is a view along arrow B of FIG. five.

The motor / drives the shaft 2 with the gears 3 vi 4 stuck on it. Through the brush 4, the rotation is transmitted to the wheel 5, and through the gear 5, 6

two mandrels 7 and 5 with screws cutting through the esternia 10 to the intermediate shaft 11.

The rotation of the intermediate shaft / 7 is transmitted through the screw 12 to the worm gear 13, carrying two rollers 14, between which the tube 15 is clamped, wrapped around the wire.

The rotation of the worm gear 13 through the rollers / is transmitted to the pipe 75. The latter, in addition, receives translational motion along its axis through the pinions 16 and 17, the intermediate shaft / 8 and the rollers 19.

The forward movement of the pipe along its axis can be obtained in another way (Figs. 2, 3, 4) with the help of rollers 14, if the latter is connected through cylindrical gears 76, 77 and bevel wheel 18 mounted on a worm wheel 13 with a fixed conical wheel 79. When the coil 5 is rotated around its axis, the wire 21 is unwound from the bobbin and wound onto the mandrels 7 and 8 in the form of elongated loops, and by rotating the mandrels the loops move from the winding point to the ends of the mandrels. Thank you

simultaneous rotation and translational movement of the tube 15, the wire pattern running down from the mandrels is wound on the tube in a spiral. The wire pattern is fastened to the pipe by flat steel wire that winds up from the roller 20 and, having passed through the hollow mandrel 8, is wound on the pipe in a 2G spiral, fastening the wire pattern inside which it passes.

The movement of all gears, coils 5, mandrels 7 and S and pipe 15 comes from a single electric motor, which guarantees the correctness of the winding of the wire pattern. A simple asynchronous motor can be used to drive the machine. Intermediate wheels, ensuring the correct ratio of the speeds of individual elements, are not shown in the diagram.

To improve the thermal contact between the wire pattern and the pipe, the subsequent pattern is soldered to the pipe using a special saw (Fig. 5, 6).

A special coil 5 is placed in the head consisting of the stand 22 on. which, by means of screws, strengthened the fixed stationary cylindrical cup 23.

Inside the glass are placed two mandrels 7, S with screw thread, interconnected by teeth, which are integral with the body of the mandrels. The mandrels are reinforced in the front and rear walls of glass 23. The anvil is made of bronze on the front wall 24 of the glass, and on the other, bronze inserts 25 and 26 are installed in the rear wall of the glass.

The outer surface of the barrel, the bearing, supports for the two ball bearings 27 and 28. The latter, in turn, are the support for the cylinder 29, which can rotate around its axis and around the fixed cup 23. On the back wall of the cylinder 29, the disk 30 is fixed, carrier ring and rollers 31.

The rotation of the cylinder 29 together with the disk 5 and the rollers 31 is carried out through the gear 32, which is wedged with a pin on the cylinder 29. The internal cavity of the cylinder 29 is protected from dust and dirt by means of seals in the front and rear walls of the cylinder. The front wall 33 of the cylinder 29 is detachable and fastened with screws to the thickened part of the cylinder 29.

A coil 5 is supported on the outer surface of the cylinder 29, which is the carrier of the coil of wire from which the wire pattern is made. The winding of the wire pattern on the rotating mandrels 7 and 5 is carried out with the help of the drive disk 30 and the guide rollers 31. When winding the wire from the coil 5, the latter slowly rotates around the cylinder 29, sliding along its surface in the same direction as the cylinder rotates. The speed of movement of the roller 5 relative to the cylinder is equal to one tenth of the number of revolutions of the cylinder 29 and the disk 30.

The subject matter of the invention.
