Description

The invention relates to the production of tires intended for use in the field of super high energy energy (microwave energy) prior to their vulcanization.

The purpose of the invention is povienne :: rotogravoditelnost devices and reduction of its dimensions in height.

FIG. 1 shows a device as seen from FIG. 2 - this is before the attachment of the prefabricated tire to the mechanism for moving it in the area of the Nagreva in FIG. 3 - the same, during the heating of the Pokrishki billet; Fig. 4 shows the mechanism for moving the tire blank in the heating zone.

The device for heating the back of the front of the zulcan posterior contains a sealed rectangular-shaped chamber 3 connected by a waveguide 1 to the microwave power source 2 with one movable side wall A, which is mounted on the chamber 3 using two mechanisms of the hinge parallelogram. the hinge parallelogram mechanism has pivoting levers 6 and 7., which are connected at one end to the side wall 4, and the other to the pillar 8 ,. mounted on the upper wall of the chamber 3, and the actuator 9 for the swing and the levers in the form of a ram cylinder. The mechanisms 5 are interconnected by a horizontal rod 10 rigidly connected with the levers 6,

In the upper wall 1 1 7: amers 3 in the rail 12 are installed with a rotatable floor 1 Tang 13 .; connected with the mechanism 14 of its rotation, mounted on the bracket 15, which makes a vertical return movement in the direction of the column 16 from the drive 17 to the rear axle 18, the lead screw 19 and the nut 20 (fig. 4) ,

At the lower end of the rod 13, radially expanding grippers 21 are hingedly mounted, which are folded up for insertion of the bore hole of the workpiece of tire 22 and the unfolded state for holding and moving the tire in the heating zone. is carried out with the help of t 23, pivotally connected with the pusher 24 placed in the central hole of the rod 13. The pusher 24 coBepiiiaeT longitudinal movement from the lever 25 connected to the pusher by means of the bearing unit 26. For an automatic The HiiH driven drive of the reciprocating movement of the tire blank to the heating zone on the rack 27 has installed end switches 28.

Inside the chamber 4, a movable carriage 30 is mounted on the horizontal guides 29 for mounting the tire blank. A mounting ring 31 is placed on the carriage 30 to set and center the workpiece along the axis of the rod 13. The carriage 30 is connected to the actuator 32 and moves in the horizontal direction with the lateral wall -4 of the chamber 3 open.

The device works as follows 3 ohm

The npPi lifted to the upper position of the wall 4 and the carriage 30 pushed forward onto the adjusting ring 31 is set to a 22 m blank workpiece. The drive 32 is turned on. The carriage along with the striker 22 moves inside the chamber 3. When the carriage moves on the adjusting ring 31, the blanket cover, Sh1kn 22, freely with a small scale, passes under the position in the folded state. These grips 21. B. The extreme position of the carriage, the locating ring with the Lokrshzhi billet becomes coaxial with the rod 13. In this position, the drive 17 is turned on for reciprocating interchange. At a short distance of the grippers from the top side of the workpiece, the pokrshn-drive drive 7 is disconnected from the end switch, the switch 28 is switched off, and the grips are stopped. Includes ;;; 25, the pusher 24 descends down the grippers 21, which are hingedly connected with the g-shaft by means of the grids 23, rotated from the center and fit under the upper side of the pokr billet. The drive / d 17 movement of the boom 13 and lift is activated. When the boom 13 is lifted, the grippers 21 capture the workpiece of the rivet under the upper side and lift it to the heating zone. The rotation mechanism 14 is turned on. The swing arms 6, rigidly connected to the rod 10 by the actuator 9, are turned downwards. With this wall 4,

Moving along the trajectory of the part of the shell, it goes down and tightly, it is pressed towards the chamber 3.

After that, the microwave energy source 2 is turned on. The energy through the waveguide is supplied to the tire blank, which in the heating zone performs rotational and reciprocating movement. The microfat- ers in the source of microwave energy and microwaves penetrate the entire thickness of the tire blank in the heating zone during rotation and axial displacement of the latter and uniformly heat it.

After the end of the heating process, the supply of microwave energy is stopped. The drive 9 is turned on and the wall 4 of the chamber rises up. The rotation mechanism 14 is also disabled.

and, the blank of the tire 22 is lowered by means of a drive 17 for the reciprocating movement. and placed on the mounting ring 31. In this position of the tire blank, the drive 17 is turned off, the downward movement of the rod 13 is stopped by the drive 25, the grips 21 fold towards the center, and by the drive 17, the rod 1013 raises the grips to its original position above the tire blank. After that, the actuator 32 is turned on, and the carriage 30 with the heated billet of coil 22 is led out of the chamber. The tire blank is removed from the carriage and transported to the vulcanizer. On the adjusting ring 31, the next blank of the caps is set and the heating process is repeated.
