Description

I

The invention relates to the manufacture of glass, ceramic pipes.

A device for cutting glass pipes is known, comprising a frame with vertical posts and horizontal guides, on which a feeding mechanism and a cutting mechanism with a drive are attached, the cutting mechanism being designed as cutting disks mounted on carriages.

The purpose of the invention is to increase the quality of the cut.

This is achieved by the fact that the feed mechanism is made in the form of levers, at the free end of one of which a tube holder is fixed, and on the other, a roller interacting with a figured copier mounted on the output shaft of the feed mechanism drive.

FIG. I shows a device for cutting glass tubes, a general view; on fng. 2. The L-A cut-out in FIG. one.

The device consists of a bed / with vertical posts 2 on which horizontal guides 5 and 4 are fixed. Levers 5 with holders 6, stops 7 and lever 8 with roller 9 fixed on its end are mounted on the guide (shaft) 4. equipped with counterweight 10.

On the frame there is a feed drive consisting of an electric motor 11, a gearbox 12 and a gearbox 13, on the output shaft of which a figure copier 14 is mounted, a roller 9 is pressed to the copier by means of counter-load.

On the guide 3, there are installed carriages 15 € 0 with spindles 16 for fastening cutting discs 17, which are driven in rotation from electric motors 18. The diameter of the disks 17 is chosen B depending on the diameter of the pipe being processed.

The device is equipped with a collector 19 for a cooling valve, to which a lever 20 with a stop 21 and a counter load 22 for supplying pipes to the holders 6 from a storage container 23 is attached. The lever 20 can be lowered to the stop 26.

The device works as follows.

From the inclined storage ring 23, the tube rolls down onto the lever 20, resting on the stop 26, and is held up by the stop 21, Then the cutting discs 17 are turned on and coolant is supplied, and then the drive of the feed mechanism is activated. Levers 5, which are in the extreme left position, turn, returning with great speed to the extreme right position, press the lever arm 20, which, turning in the joint, rolls the pipe through the stops 21 into the holders 6 of the levers 5. Holders 6 can be changed be in accordance with the diameter of the pipe being cut. The levers 5 carrying the pipe, at high speed, SUPPLY it to the cutting disks 17, which are installed by means of the movable carriages 15, at a given size of the pipe being cut. The process of embedding discs and their exit is very slow. As soon as the pipe is cut, the support 7 presses the levers 24, and the pipe rolls onto the guides 25, and the levers 5 return to the extreme right position at a greater speed, the cycle repeats. The entire working cycle and idling of the levers 5 are carried out by turning the shaft 4 by running the roller 5 along the figure copier 14, the profile of which is constructed in accordance with the predetermined variable angular velocities of the levers 5 in each section of the working cycle. Subject matter of the invention. A device for cutting glass pipes, including a stanchion with vertical posts and horizontal guides, on which a feed mechanism and a cutting mechanism with a drive are fixed, the cutting mechanism being designed as cutting disks fixed to the carriages , characterized in that, in order to improve the quality of cutting, the feed mechanism is made in the form of levers, on a free shaft of one of which a tube holder is fixed, and on the other - a roller, interacting with a figured copier, mounted on the output shaft of the drive mechanism iodachi.
