Description

.

The invention relates to the glass industry and can be used to make thin-walled seamless hollow articles, such as incandescent bulbs.

The aim of the invention is to increase the yield of glass products and increase the durability of the tube.

On the phage. 1 shows a tube, an incision; in fig. 2 - the interposition of the mouthpiece and the working ring.

The glass tube contains a plunger 1 on which a mouthpiece 2 is mounted with a locknut 3. A core 4 with holes in the center and at the periphery is located at the same distance from each other in the mouthpiece 2. Moreover, the peripheral holes are located from the end surface of the core 4 under the plunger to the outer side of its surface at an angle to the horizon. An air tube 5 is attached to the plunger 1, into the slot of which is inserted a branch pipe 6, which is closed by a cap 7. A fluoroplastic seal 8 fixed by a nut 9 is mounted between the plunger 1 and the air tube 5 fixed as a pin 9. Concentric mouthpiece 2 has an operating ring 10 placed in desktop nest 11.

The glass tube operates as follows.

The working ring 10 of the blowing tube is lowered, the mouthpiece 2 enters the opening of the working ring 10 by 2–3 mm and presses the necessary amount of glass mass through it and a prestressing begins. At the same time, the worktable 1 1 rotates and transmits the rotation by means of the mouthpiece 2 through the glass melt to the sensing tube. After the final blowing of the flask, the extruding tube rises up to its original position, the rotation of the working table 11 stops and after removing the finished flask the cooling of the mouthpiece 2 and the working ring 10 begins, after which the blowing tube starts the next cycle of operation.

By setting the core

20 into the mouth of the mouthpiece, the surface of the contact between the mouthpiece and the glass melt significantly increases, which contributes to the normal blowing of the flask. In addition, in the course of the combined local work, the mouthpiece enters the opening of the working ring, thus significantly increasing their durability. Due to the fact that the nozzle enters the socket of the air tube with

0 the possibility of free rotation, and the air tube is fixed to the plunger by means of a sealant in the form of a fluoroplastic seal, to the plunger;

3 mixing air from the pneumatic cylinder with sensory air, which contributes to the normal vyschuvaniyu flask.

Claims (1)

A GLASS BLOWING TUBE containing a plunger connected by means of a thread to an air tube, in the fixture socket of which a pipe is mounted with its piston-shaped part and a mouthpiece connected to the plunger, characterized in that, in order to increase the yield of glassware and increase the durability of the tube, it is provided a core with a central hole mounted on the plunger installed in the mouthpiece of the mouthpiece and peripheral located from the end surface under the plunger to its outer lateral surface at an angle to the horizontal of the same distance from each other, and the pipe is installed with the possibility of free rotation.
