Description

The invention relates to equipment for the tire industry and is intended for winding bead rings of single wire.

The purpose of the invention is to improve the quality of the winding of the side rings for adjusting the clamping force of the end of the wire. .

FIG. 1 schematically shows a template for winding the side rings in the initial position; in fig. 2 the same in the working position; in fig. 3 - template with side ring, cross section; in fig. 4 is a view And in figure 1.

Template for ./ winding side rings contains mounted on axis 1 discs 2 and 3, installed with the possibility of axial movement and joint vras: Eu. The disk 3 has a spline 4 with an inclined surface 5. In the groove 6, by means of the axis 7, means for clamping the end of the wire are mounted, having a protruding part 8 for interacting with the protrusion 4 of the disk 3 and spring loaded 9 with respect to the disk 2.

clamp end of the wire in the form of two shoulders lever Yu, on the free end of which is mounted an adjustable stop 11 in the form of a screw. Axis 7 is mounted in a plane perpendicular to the axis of symmetry of the pattern.

The device works as follows.

The wire 12 is fed into the groove 6 of the disk 2. Then the disks 2 and 3 are shifted to form a groove for winding the side ring 13 of the desired configuration

When the disks 2 and 3 approach the lever 10, the anvil 11 interacts with the disk 2 and rotates around the axis 7, pressing the wire 12 to the disk 2. Then, when the disks 2 and 3 rotate together, the winding of the ring 13 plays out. At the end of the winding, the disks 2 and 3 move apart lever 10 is returned to its original position by spring 9. Ring 13 is removed from the template. Then the cycle repeats.

The stop 11 regulates the force of pressing the wire with the 12 two-arm lever 10 against the disk 2.
