Description

Compasses knife for glass cutting

Technical Field

The invention relates to the technical field of glass cutting equipment, in particular to a compasses knife for cutting glass.

Background

Glass is a common material in life, and the wide application range of the glass almost includes various fields in life, so in order to adapt to the application range of the glass, the glass needs to be cut into different shapes and sizes in the using process, wherein the common shape and structure is a rectangle or a circle.

And to the glass of rectangle structure, can directly use glass sword and guiding ruler to cut off according to the size, and to the glass of circular structure, then must cut off it with special compasses sword, at present, the use of compasses sword is with its one end absorption on glass, adjusts and controls the diameter of cutting through the distance of adjusting between scale upper knife rest and the sucking disc.

However, in the existing compass knife, a ruler is connected with a sucker in a pin joint mode, a knife head and the bottom end of the sucker are kept on the same horizontal plane, when the compass knife is adjusted to be adsorbed on glass for cutting, the knife needs to be pressed down to mark a trace on the glass, so that when the knife head is pressed down, the ruler and the knife head are inclined synchronously, the marked trace is smaller relative to the scale on the ruler, the marking and cutting precision is poor, artificial pressure is needed when the knife is pressed down, the uniformity of stress among all parts is poor when the compass knife cuts a circle on the glass, the compass knife is difficult to break off the edge, the integrity is poor, and the edge burrs are more, so that the quality of the compass knife for cutting the glass is poor.

Disclosure of Invention

Technical problem to be solved

The invention provides a compasses knife for glass scribing, which has the advantages of no tool inclination when pressing down and scribing, higher scribing and cutting precision, uniform pressure, higher integrity when breaking off edges and lower quality of edge burrs, solves the problems that the prior compasses knife adopts a pin connection mode between a scale and a sucker, a knife head and the bottom end of the sucker are kept on the same horizontal plane, when the compasses knife is adsorbed on glass for cutting after the size is adjusted, the compasses knife needs to be pressed down to scribe traces on the glass, so that the scale and the knife head are inclined synchronously when the knife head is pressed down, the scribed traces are smaller relative to the scales on the scale, the scribing and cutting precision is poorer, and the compasses knife needs artificial pressure when pressing down, so that the uniformity of stress among all parts is poorer when the compasses knife cuts a circle on the glass, therefore, the glass cutting machine is difficult to break edges, poor in integrity and high in edge burr, and accordingly the glass cutting machine is poor in quality.
