Abstract

FIELD: transportation.

SUBSTANCE: sectors are pivotally mounted on the drive shaft. At one end of the hinge arms, cylindrical flat hinges are formed, which are mounted in the axial closed grooves along the outer cylindrical surface of the bushing, abut against the ends of the axial closed grooves and into the rim of the casing embracing the cylindrical flat hinges. Each holder is fastened to the bushing using a union nut mounted on the threaded part of the bushing. The ring stop of the union nut interacts periodically with the annular stop of the power nut mounted on the drive shaft threads, and the axial closed grooves are made at an angle to the axis of the drive shaft rotation.

EFFECT: creating a device for assembling rubber-cord shells of ballon type of small diameter with clincher beads.

Description

The invention relates to equipment of the tire industry, in particular for the assembly of rubber-cord casings, balloon type of small diameter with clincher sides.

It is known (author's certificate No. 493370 IPC B29D 17/16, publ. 30.11.75, bull. No. 44) a device for assembling rubber-cord shells containing auxiliary and main expandable sector drums mounted on a drive shaft, the last of which is equipped with a mechanism for expanding its sectors, in the form of an annular cylinder concentrically mounted in it with two pistons and axial spring systems.

A disadvantage of the known device for assembling rubber-cord shells is that it is impossible to collect blanks of rubber-cord shells of small diameter on it.

A device for assembling tires containing a drum with expandable cones and sectors mounted on the axis is known (auth. Certificate No. 441769 IPC B29D 17-16 published on 05/15/79, bull. No. 18), the expanding cones being rigidly mounted on movable cylindrical guides, one of which is connected with the drum rotation drive, and interconnected by means of the drum axis freely installed in them.

A disadvantage of the known device for assembling tires is that it does not provide for the assembly of blanks of shells of the balloon type of small diameter with clincher sides.

The technical result of the claimed technical solution is to create a device for assembling rubber-cord shells of a balloon type of small diameter with clincher sides.

The technical result is achieved by the fact that the sectors are pivotally mounted on the drive shaft, while cylindrical flat hinges are made at one end of the pivot arms, which are mounted in axial closed grooves along the outer cylindrical surface of the sleeve and abut against the ends of the axial closed grooves and into the support of the sleeve, covering cylindrical flat hinges.

Each cage is fixed to the sleeve using a union nut mounted on the threaded part of the sleeve, and the annular emphasis of the union nut periodically interacts with the annular emphasis of the power nut mounted on the thread of the drive shaft, and axial closed grooves are made at an angle to the axis of rotation of the drive shaft.

The essence of the invention is illustrated by the following drawings:

FIG. 1 - a device for assembling rubber-cord shells in the initial position, sectors are compressed;

FIG. 2 - a device for assembling rubber-cord shells in a working position, sectors are unclenched;

FIG. 3 - a device for the assembly of rubber-cord shells, section AA;

FIG. 4 - assembled blank rubber-cord shell.

A device for assembling rubber-cord shells comprises sectors 2 pivotally mounted on a drive shaft 1, which are connected to articulated levers 3, at one end of which cylindrical flat joints 4 are made, mounted in axial closed grooves 5 along the outer cylindrical surface of the sleeve 6, abut against the ends 7 axial closed grooves 5 and an abutment 8 of the sleeve 9, covering cylindrical flat hinges 4. Each sleeve 9 is mounted on the sleeve 6 using a union nut 10 mounted on the threaded part 11 of the sleeve 6 having a ring second abutment 12, which periodically interacts with the annular ledge 13 force nut 14 mounted on the thread 15 of the drive shaft 1. The axial grooves 5 are closed at an angle α to the axis of rotation of the drive shaft 1 for mounting and dismounting convenience hinge levers 3.

The inventive device for assembling rubber-cord shells works as follows.

On the outer diameter of the drive shaft 1 and sectors 2 located in the initial position (Fig. 1, 2) impose the required number of layers of rubberized cord. The drive shaft 1 is rotated on itself and at the same time, the hand nuts 16 hold the power nuts 14, one of which has a left-hand thread, the other a right-hand thread. Each nut 14 moves along the thread 15 of the drive shaft 1 in the direction of the sectors 2 and the annular stop 13 abuts through the sliding bearing 17 against the end of the threaded part 11 of the sleeve 6. The sleeve 6 moves together with the cage 9, which acts by the stop 8 on the flat hinges 4 of the hinge arms 3 and, in this way, sectors 2 which form a cone are bred (FIG. 2). Next, they wind the bead rings, wrap the cord layers on the bead rings, impose a cover layer (not shown in FIG.) Of the cord. The drive shaft 1 is rotated away from it and at the same time the power nuts 14 are held by the handles 16. Each nut 14 moves along the thread 15 of the drive shaft 1 in the direction from sectors 2 and the ring stop 13 abuts against the ring stop 12 of the union nut 10. The sleeve moves together with the cage 9 , affects the ends 7 on the flat hinges 4 of the articulated levers 3 and sectors 2 are folded into the initial position (Fig. 1). Then remove the assembled workpiece product (Fig. 4).

Thus, the device for assembling rubber-cord shells provides the assembly of blanks of shells of the balloon type of small diameter with clincher sides.
