The invention relates to equipment for the tire industry, and is intended for the manufacture of bead rings of various sections from a single rubberized wire.

The purpose of the invention is to increase the reliability of the device and its performance.

FIG. 1 shows a device for making side rings, a general view; in fig. 2 shows section A-A in FIG. one; in FIG. 3 a section BB in FIG. one; in fig. 4 is a view of B in FIG. 2; in fig. 5 is a section of YYD in FIG. four.

A device for making side rings comprises a frame 1 and an installed

The template discs 2 are divorced, wire cut 24 is extended through the direction of yush, tube 17 and passes in the annular groove in the lower part of the laying roller 6. The free end of the wire 24 extends beyond the limits of the laying roller 6.

Under the action of the pneumatic cylinder 12, the bracket 11 with the carriage 7, the roller 6 and the tube 17 with the rubber-coated wire 24 is lowered down to the template so that the folding roller 6 is installed at the starting point of the coiled ring.

Simultaneously with the pneumatic cylinder 12, the pneumatic actuator 14 is turned on and through the slide 15 with the help of the finger 16 turns down

On the drive pattern 2, the mechanism 3 pO- - (5 clamping lever 13, the deflection is rubberized20

cottages and laying the wire and the mechanism 4 cuttings mounted on a rack 5 mounted on the frame 1.

The mechanism 3 for feeding and laying rubberized wire comprises laying on a roller 6 with an annular groove and for a wire mounted on a carriage 7, driven by a stepper motor 8 with a transmission mechanism 9. The carriage has the ability to move along guides 10 mounted on a bracket 11 , 25 to ensure the laying of the wire on the template. The bracket 11 is mounted for vertical movement by means of a pneumatic cylinder 12,

The carriage 7 is provided with a mechanism for threading the wire into the lock, with the lever 13, mounted on the axis of the stacking roller 6, rotatable around it, connected to the pneumatic actuator 14 by means of the linker 15 fixed on the rod b using the lever 13 and the hole finger scenes 16. The surface of the lever 13 facing the wire has a concave profile, a slope corresponding to the location of the wire, and a cutout g extending in the direction of the lead wire (Fig. 5). On the carriage 7, a guide tube 17 is installed for feeding the wire into the groove of the paving roller 6, provided in the upper part with a longitudinal groove c.

The wheelhouse mechanism contains a fixed one. knife 18 and movable 19, connected with pneumatic cylinder 20.

The template for winding the side rings consists of a disk 21 which is stationary in the axial direction and a disk 22 moving along the axis of rotation, forming a shaped groove in a shifted position 50 on the outer surface. A lock 23 is mounted on the disk 22 in the plane of the connector to secure the end of the rubber wire.

The device works as follows

Before starting the winding of the ring, the mechanism 3 for feeding and laying the wire is displaced by means of a pneumatic cylinder 12 into the upper full wire 24 to the bottom of the groove of the stacking roller 6 and holding it with a concave shaped surface to the lever 13 from lateral displacement. Thus, the wire is threaded into the space between the discs 21 and 22 of the template in the lock 23. Then the pneumatic actuator 14 retracts the lever 13 to its original position. The disk 22 moves to the disk 21, clamping the rubberized wire in the lock 23. The template starts to rotate and simultaneously under the action of the engine 8 with the transmission mechanism 9 begins to move along the guides 10 the carriage 7 with the guide tube 17 and the laying roller 6, in the ring groove and which The rubberized wire passes, which is placed in the shaped groove to the template according to a specific program.

After winding up the ring, the bracket 11 with the carriage 7, the drive 8 and the laying roller 6 is retracted upwardly by means of the pneumatic cylinder 12, the rubberized wire is introduced into the space between the stationary 18 and the movable 19 knives of the cutting mechanism, the pneumatic cylinder 20 moves the knife 19 and chopping wire. The disks 21 and 22 of the pattern are divorced and the finished bead ring is dropped into the space between them. Then the cycle repeats.
