Glass cutting device

Abstract

The invention discloses a glass cutting device. The glass cutting device comprises a cutter body, a cooling device and a support. The cutter body and the cooling device are arranged side by side and are connected through the support. The cutter body, the support and the cooling device are sequentially distributed in the cutting and moving direction. The cutter body comprises a cutting frame connected with one end of the support, and a cutter wheel connected to the bottom of the cutting frame through a wheel pin. The cooling device comprises a supporting plate connected with the other end of the support, and a first gas spray nozzle arranged on the bottom face of the supporting plate and facing the cutter wheel. Cooling gas is input into the first gas spray nozzle through a gas conveying pipe. The glass cutting device is compact in structure, convenient to disassemble and assemble, easy to manufacture, safe, reliable and high in practicability. The cutter wheel is effectively cooled, and the service life is prolonged. Glass chippings raised by the cutter wheel are rapidly cooled, dust prevention is achieved, the glass chippings are prevented from being attached the surface of glass, and contamination is reduced.

Description

technical field [0001] The invention relates to a cutting device, in particular to a glass cutting device. Background technique [0002] At present, the demand for glass in the market is increasing day by day, and there are more and more types and sizes of widely used glass. This puts forward higher requirements for the performance and dimensional accuracy of the glass. Small size, high strength and rigidity, uniform material, and require high efficiency and speed in glass cutting and production. [0003] Usually, in glass cutting, a roller made of diamond sintered body or superhard alloy with a diameter of several millimeters and a ridgeline on its circumference moves while applying a certain pressure on the glass surface; It moves while penetrating into the glass surface, and moves while forming horizontal scratches with a width of several micrometers in depth and width, and at the same time, forms tens of μm perpendicular to the glass surface inside the glass directly be...

AI Technical Summary

Problems solved by technology

[0004] Among them, vertical cracks are a necessary condition for the subsequent glass separation process. However, the horizontal scratches generated during the scribing process will not only affect the edge quality of the glass after separation, that is, the fracture surface is not smooth enough after the glass is broken, but also excess glass debris will appear.

Glass debris will adhere to the glass surface and cause scratches or pollution to the glass surface in the subsequent process, thus directly affecting the quality of the product; at the same time, the raised glass debris will also pollute the environment of the clean workshop

In addition, when the roller is cutting, the cutting temperature is high, resulting in a short service life
