Device for locking steel traveler of tyre builder

Abstract

The wire ring locking device of the tire building machine, the sliding flange is set on the main shaft of the shaping drum, the outer positioning platform is fixedly connected with the inner positioning platform of the annular connecting sleeve, and a plurality of driving cylinders are evenly distributed on the outer side of the connecting sleeve, and the outer edge of the connecting sleeve is fixed. Position the chuck. The piston rods of each cylinder pass through the fixed push plate through the hole of the connecting sleeve to hinge a plurality of connecting rods and crank claws, and the turning points of the crank claws are hinged to the swivel seat on the connecting sleeve. After the carcass tube traveler reaches the positioning chuck, the driving cylinder simultaneously pushes the multiple crank claws of the push plate to swing outwards at the same time, and the opened pressure plate locks the traveler on the positioning chuck. The sliding flange sleeve moves inward for forming operations. After completion, each cylinder shrinks to drive each crank claw to swing inwardly, and the pressing plate is closed at the same time to disengage from the traveler. The sliding flange sleeve is moved outward, the traveler is separated from the positioning chuck, and the tire can be unloaded. The device replaces the capsule to realize the locking and positioning of the steel traveler, has high efficiency, strong reliability, long service life, less maintenance, and is beneficial to improve tire quality.

Description

(1) Technical field [0001] The invention relates to tire building machine technology, in particular to a bead ring locking device for a tire building machine. (2) Background technology [0002] In the current two-stage all-steel tire second-stage building machine, after the wire ring of the carcass tube from the first-stage machine reaches the stop of the positioning chuck, the locking of the wire ring and the positioning chuck is through the inside of the carcass tube. The inflation expansion of the capsule is realized. The volume of the capsule is large, and the inflation time is long. Moreover, in order to align the loading and alignment of the carcass tube traveler, the capsule needs to be repeatedly inflated and deflated several times during the operation process, and the labor intensity of the workers is high. In particular, the stretching of the capsule is inconsistent due to repeated inflation and deflation, which affects the symmetry and balance of the tire produce...

AI Technical Summary

Problems solved by technology

The capsule is large in size and takes a long time to inflate, and in order to align the carcass tube traveler, the capsule needs to be repeatedly inflated and deflated several times during the operation process, and the labor intensity of the workers is high

In particular, due to repeated inflation and deflation, the stretching of the bladder is inconsistent, which affects the symmetry and balance of the produced tires, which is not conducive to improving the quality of the tires, and will reduce the service life of the tires

The capsule itself is a vulnerable part with low safety performance

It is also difficult to replace the capsule after wear and aging

In particular, the volume of the capsule used in the giant tire is huge, the manufacturing precision is high, molding and vulcanization are very difficult, and the yield is low, so the cost of a single capsule is relatively high.

If the traveler bladder is repeatedly inflated and deflated to lock the carcass tube, the service life of the bladder will be reduced and the production cost of the tire will be increased.
