Description

one

The invention relates to the manufacture of glass products and can be applied in the electrovacuum industry, in particular for the manufacture of the pingels and bars of various light sources and electronic devices.

A device comprising a bunker magazine, a transporter and a cutting body, made as a separate unit of several circular knives, mounted on a common rotating shaft, allowing cutting of a round glass blank along its entire length 1, is known.

However, the known device has a poor cut quality, which occurs because the workpiece with ring-shaped risks is very sensitive to the slightest blows and often breaks off prematurely in the knife zone, causing cut parts that are not supported, chaotically hitting the rotating knives, cracking and razla; The premature breaking of blanks is also facilitated by the slight difference in the sizes of the diameters of the circular knives and the curvature of the blanks.

The closest to the invention to a technical solution is a device for cutting glassware, mainly glass tubes, containing a feed conveyor, a slider with Uior, and blocks of knives mounted above it with the ability to move in vertical or plane 2.

The disadvantage of this device lies in the low quality of the cut.

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

This is achieved by the fact that the device is equipped with a beam with stops placed by blocks of knives, each uior located

against the knife, and the knife blocks are mounted for movement in a horizontal plane.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows a cutting and fragment assembly, a section along A-A in FIG. one.

The device comprises statiin 1, a bunker shop 2, a conveyor 3 for feeding the tubes to a cutting unit and fragments. The conveyor is driven into an intermittent motion by an asterisk 4, which receives rotation from the drive shaft 5 through a crane mechanism 6. The cutting and fragment assembly includes a slider 7 with podruzhennymi stops 8, driven in the vertical plane from the cam 9, and a block of 10 knives with spring-loaded knives And , receiving movement in the vertical plane from the cam 12, and in the horizontal plane from the cam 13. The beam 14 with the stops 15 is fixed motionless. The block 16 with spring-loaded knives 17 is mounted for movement in vertical and horizontal planes, respectively, from cams 18 and 19. Cut and broken workpieces along tray 20 are collected in box 21. The stops 8 and 15 are equipped with catchers, and a knife is placed against each stop .

The device works as follows.

Billets (1000-1200 mm long) are stacked into the bunker with a pile, conveyor 3 captures the blanks from the bunker and supplies 10 and 16 knives between the blocks. After stopping the conveyor, the slider 7 with stops and blocks 10 and 16 knives make a movement in a vertical plane. Moving up the slider 7 with its catchers, it seizes several, for example, 4 droplets and lifts them up, rests against the fixed stops 15 of the beam 14, while the spring-loaded knives 11 and 17 abut against the workpieces from below and above with sufficient force. Then the blocks 10 and 16 knives make a reciprocating movement in the horizontal plane, forming a checkerboard located risks (scratches) on the workpieces, i.e. one risk from above, adjacent to the bottom. To further break the blanks for these risks, the blocks 10 and 16 of the knives move away from the blanks, which remain fixedly pressed between the stops 8 and 15, after which

slider 7 with stops receives an additional upward movement, and blanks break down on risks. The cut parts pass through the inclined tray 20 into the accumulator 21. The blocks 10, 16 of the knives and the slider with the stops 7 again return to their original position, opening the way for supplying a new batch of blanks and the cycle is repeated.
