SU757345A1 - Template for winding bead rings - Google Patents

Description

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

Known pattern that contains the base, fixed and movable segments, the clamp attached to the hinge axis, and the starter that controls the clip through the roller and the cam mechanism [1].

However, the known pattern is complicated in construction, the operations for clamping, loosening and resetting the wound ring are performed by separate mechanisms, as well as a small opening, into which the wire is fed for clamping, and the position of the wire clamp is at an angle to the main axis of the template, which causes inconvenience .

Also known is another pattern for winding side rings, containing radially movable segments mounted on the housing, a mechanism for their simultaneous breeding and a mechanism for gripping the wire [2].

A disadvantage of the known construction also consists in the fact that the device is complicated in design, the template has separate mechanisms for gripping the wire, loosening and dropping the ring, the jaws, into which

the wire is small and the wire clamping point is at an angle to the main axis of the pattern.

The purpose of the invention is to simplify the design.

₅ This goal is achieved by the fact that in the winding template of side rings containing radially movable segments installed on the housing, a mechanism for simultaneous dilution and a mechanism for gripping the wire, a mechanism for gripping the wire is designed as moving along the guides fixed on the segment slide with a hole is rigidly associated with the slider and fixed to the pneumatic cylinder segment equipped at its end ¹⁵ pas Zoom clamp mounted in a hole of the slider with the possibility th displacement in the perpendicular direction of the slider movement and the actuator to move clamping when pitting bortovo2o th ring, the free end of which rod

designed as a plug.

view B in FIG. 2; in fig. 4-5 - successive stages of the template.

The template contains radially movable segments 1 installed on the housing, a mechanism 2 for simultaneous dilution and a mechanism for gripping the wire made as mounted along the guides 3 fixed on the segment 1 of the slide 4 with an opening a and rigidly connected to the segment fixed on it 1 pneumatic cylinder 5 through the rod 6, and provided at its end with a groove b clamp 7 installed in the hole and the slide 4 can be moved in a plane perpendicular to the plane of movement the slider 4, and associated with the power cylinder 8, the rod 9 of which at its free end is made in the form of a fork 10, interacting with the groove b. The power cylinder 8 is permanently installed outside the template.

The template works as follows.

The slider 4 together with the clamp 7, which is in its extreme front position, is moved by means of the rod 6 and pneumatic cylinder 5 to the upper extreme position along the guides 3. As a result, a jaw is formed into which the end of the wire is fed. After that, the pneumatic cylinder 5 releases the slider 4 to the lowest position and presses the wire to sector 1. The template starts to rotate, winding the wire onto clip 7. After 3-5 turns of pneumatic cylinder 5, the air is relieved to remove the excess force that is now clamping the end of the wires. Groove b when rotating the template all the time passes through the fork 10. After the required number of turns, the template stops at the position where the groove b finds on the fork 10. With the help of the cylinder 8 of the rod 9 and the interacting fork 10 and the groove b the clip 7 moves to the extreme rear position , getting rid of the wound ring, while the ring is weakened. The edge of the template does not allow the clamp to carry away the ring. Then the cylinder 8 moves the clamp 7 to the extreme

₅ front position and resets the ring. The proposed template allows you to simplify the well-known design, reduce the number of parts, as well as improve serviceability, as the mouth increases,

into which the wire moves.
