Abstract

1. A method of cutting sheet glass by applying cutting lines and a subsequent fracture, which also means that, in order to improve the quality of cutting and reduce bo, a longitudinal cut is performed against the stroke of the glass sheet periodically at a cutting speed for glass 3-6 mm thick - 0.02-0.04 m / s, thickness 6-10 mm - 0.04-0.18 m / s, thickness 10-16 mm - 0.18-0.5 m / s, 16 mm thick and above - 0.5-1 m / s.

Description

2. A device for resrci sheet glass, including a frame with a vacuum pump and, glass-cutter carriages, an electric motor control system, characterized in that, in order to improve the quality

cutting and bob glass reduction, the control system is made with a suction pad lifting mechanism in the form of a lever with a figured protrusion and with a control valve with a plate connecting the suction cups with a vacuum pump.

The invention relates to the permeability of construction and building materials, in particular to glass making - to cutting sheet glass of predominantly thick denominations, and can be applied to glass factories. cutting glass ribbon thicker than 8 mm. A device for cutting cast glass is known, which includes a frame with vacuum suction cups, carriages with cuts, a control system with an electric motor zl. The drawback of the device lies in the absence of a cutting control system, which makes it difficult to maintain the device, as well as in cutting the glass at the same randomly set speed. This degrades the quality of the glass ends and leads to a higher percentage of glass bo. The aim of the invention is to improve the quality of the cut and reduce the bo glass. The goal is achieved by the method of cutting sheet glass by applying cutting lines and subsequent breaking, a longitudinal cut is carried out against the stroke of the glass sheet periodically with a cutting speed for glass 3-6 mm thick 0.02-0.04 m7s, 6 10 mm 0, 04-0.18 m / s, 10-16 mm 0, 18-0.5 m / s, 16 mm thick and the top is 0.5-1 m / s. In a device for cutting sheet glass, including a frame with vacuum suction cups, glass cutting carriages, an electric motor control system, the control system is made with a vacuum suction mechanism in the form of a lever with a figured protrusion and with a control valve with a bar 5 connecting the vacuum suction cups with vacuum pump. In FIG. 1 shows the proposed device, a plan view, FIG. 2 figure ledge in the extreme right position; in fig. 3 - the moment when the suction cup is aligned with the hole of the vacuum pump. The movable frame 1 is moved inside the fixed frame 2 by means of an electric motor and a gearbox 3, transmitting the torque to the shaft 4. The device is placed on the roller table above the moving glass ribbon. The motor is turned on and off by limit switches 5 and 6 when they interact with lever 7, the motor is powered by a thyristor drive, which provides the moving speed of the moving frame in the range of 0.02-1 m / s, two are fixed to the moving frame on the spring-loaded system cutting heads 8 and 9. The motor is capable of moving the frame only against the stroke of the glass ribbon. For this, two suction cups 10 and 11 are provided, which automatically descend on the glass at the right moment with a figure lever 12 and a valve 13 connecting the suction cup with a vacuum pump. The device works as follows. The longitudinal cut is carried out by the lowered cutters with the ode of the movable frame against the direction of movement of the glass ribbon. When the frame is pushed to the extreme position, the figured lever 12 is pressed by the support 14 to the extreme right position, and the suction cupboard slides along the bevel (the figured lever and lowers onto the glass. the suction cup holes with the vacuum pump hole. In order to reduce the friction of the moving part of the valve and facilitate the shift of the parts, the polishing parts are polished to 9 degrees of purity, which ensures the degree of vacuum of the suction cup 50-100 mm water column and reliable grip suction cups with glass. Moving the frame with lowered cutters dragging the glass to its original position until the lever 12 interacts with the stop 18, which moves the lever to the left. Next, the lever with the valve 1-3 interacts with the stop 16, as a result of which the movable part of the valve is shifted, disconnected from the vacuum pump and connected to the drainage opening 17. Air rushes towards the suction cup and due to the elastic forces of the lever 12 is above glass. At the same time, the lever 7 turns on the end dispenser and supplies voltage to the electric motor 3. The cycle repeats again. In this way, periodic longitudinal cutting is performed, but with a continuous cutting line. Cutting is fully mechanized and does not require additional involvement of staff. This site is serviced by one setup man.
