Abstract

FIELD: construction.

SUBSTANCE: device for glass cutting comprises an element of impact at glass or a handle. At the same time the element of impact at glass is made in the form of movable platforms connected rigidly to each other by links and connected with a power stem, which interacts with a body of a device via thread, and grids of knives with cells for items placed on fixed platforms that are also rigidly connected to each other by links. The handle is made as detachable and interacts with a power stem via a joint with a ledge and slots, and glass at the same time is placed onto grids from knives and is equipped with a heater for its heating to temperature of glass softening.

EFFECT: reduced labour costs for manufacturing of items and simplified process of cutting of fine items.

Description

The invention relates to the glass industry and can be used in the continuous production of small glass products.

Known devices for manual cutting of glass, such as glass cutters, diamonds. Such cutting is inefficient and is used for cutting piece products. It is difficult to cut curved products.

Known devices for mechanical automated glass cutting (P.2248944 C1).

Known devices for laser cutting (P. 202444 C1).

It is difficult for them to carry out curly cutting, especially of small products. Cutting requires highly qualified specialists.

A device is known that contains an element of impact on glass, a handle (A.2259963 C1, prototype). The device allows direct and curved cutting. But at the same time, the cost of cutting one product is large. Glass cutting of small products is especially ineffective.

The purpose of the invention is to reduce labor costs for the manufacture of one glass product, to simplify the cutting process for small products.

The goal is achieved by the fact that in the invention, containing the impact element and the handle, the glass impact element is made in the form of movable platforms rigidly interconnected by jumpers and connected to the power rod, in the form of grids of knives with cells for products placed on fixed platforms, rigidly interconnected by jumpers. The handle is removable and interacts with the power rod through the connection. In this case, the glass is placed on the grids of knives and heated to a softening temperature using a porous element connected by a pipe to a tank filled with fuel and using an electric heater.

Figure 1 is a General view of the device in section.

Figure 2 is an example of the shape of the lattice for knives under nail files.

The glass cutting device consists of a furnace (see figure 1) with insulation (not shown), in which power elements 2 are placed, rigidly interconnected by jumpers 3 (not completely shown), platforms 4, rigidly interconnected by jumpers 5 and supplied on wheels 6. On the platform 4 are placed and fixed lattices of knives 7, representing molds for products (see figure 2). Power elements 2 are connected to the rod 8, interacting with the housing through a threaded connection, and to the handle 9 through the connection 10 in the form of a groove and a protrusion.

The furnace 1 is equipped with a porous element 11, the channel of which is connected via a pipe 12 to a container 13 filled with a combustible mixture, for example, alcohol. The furnace 1 is also equipped with an electric heater 14, inlet 15 and outlet 16 pipes for supplying and discharging a coolant, such as hot air. The platforms 4 are provided with protrusions 17 for fixing the glasses 18 on the platform. Lattices from knives 7 can be made of ceramic or special steel.

The device operates as follows. On the platform 4, lattices of knives 7 are installed and are fixed using the insert on the platform 4. Glasses 18 are installed on the grating of the knives 7. The protrusions 17 hold them against displacement. Next, the furnace closes and the glass 18 is heated to a softening temperature (700 ÷ 750 ° C). At this temperature, glass is cut with ordinary scissors.

Heating is carried out in one of the known ways, for example using a porous element 11. For this, using the valve 19, alcohol is opened from the tank 13 through a pipe 12 into the channel of the porous element 11, which is impregnated with alcohol and ignited. Using a sensor and a temperature indicator (not shown), the temperature in the furnace is monitored. When heated to a softening temperature of glass 18, the flow of flammable liquid by the valve 19 is stopped. Subsequently, the required temperature is maintained by the electric heater 14.

The furnace can be heated by an external heater, for example, hot air from an industrial hair dryer through inlet 15 and outlet 16 nozzles. When the glasses 18 are heated to a softening temperature, the glass is cut, for which a handle 9 is mounted on the rod 8 and its power elements 2 are lowered, which press the glasses 18 and push them into the grating through the knives 7. For full indentation with a glass thickness of 2 mm and the height of the knives 3 mm on the power elements can be installed protrusions with a height of, for example 1 mm To simplify the design, they may not be. In this case, the power elements 2 reach the knives, and then the temperature of the furnace rises, for example, by 50 ° C, and under the own weight of the glass 18 they reach the base of the platform 4. To eliminate the possibility of a direct effect of the power elements 2 on the knives and their deformation, a limiter is installed stroke power elements 2 (not shown). After pressing the glasses into the grating of the platform 4, together with the gratings and glasses, they are rolled out of the furnace 1 using the wheels 6. The cooling of the glasses (products) can be both in the furnace 1 and outside it.

An example for cutting glass into nail files (figure 2). When the thickness of the power elements is 4 mm, the thickness of the glass is 2 mm, the height of the knives is 3 mm, the gap between the glass 18 and the power element 2 is 2 mm, the thickness of the platform is 4 mm, with the internal size of the furnace 240 × 400 × 1000 mm, and the glass size is 2 × 150 × 310 mm and 2 × 12 × 140 mm files, you can get 1300 files for one lowering of the rod 8 and power elements 2.

Installation for cutting glass allows you to reduce labor costs for the manufacture of one product, simplifies the manufacturing process of products.

When working on the proposed invention, the materials of inventions were considered according to patents: 2259963 C1 (prototype), 2248944 C1, 2044703 C1, 2024441 C1, 2270175 C2.
