Numerical control stone thin plate cutting machine

Abstract

A numerical control stone thin plate cutting machine comprises a machine base. A stone thin plate cutting mechanism arranged below a machine base top beam is arranged on the machine base. The stone thin plate cutting mechanism comprises a transverse guide column. A driving saw wheel, a driven saw wheel and a main power motor driving the driving saw wheel to rotate are arranged on the transverse guide column. An annular belt-shaped saw blade connecting the driving saw wheel and the driven saw wheel is arranged between the driving saw wheel and the driven saw wheel. The stone thin plate cutting mechanism further comprises a hydraulic tightening system which outputs stable tightening pressure to the driven saw wheel to keep a stable working state of the saw blade. By arranging the hydraulic tightening system, the stable tightening pressure is output to the driven saw wheel to keep the stable working state of the saw blade, so that cutting quality of stone thin plates and the device operation safety are improved. Meanwhile, rejection rate is reduced, loss of stones in a machining process is reduced, stone resource is saved, and production cost is reduced.

Description

technical field [0001] The invention relates to a stone cutting device, in particular to a numerically controlled stone thin plate cutting machine. Background technique [0002] Stone is an important construction and decoration material, and its production and processing directly affect the aesthetic feeling and decoration effect of the building. Most natural stones need to be processed before they can be used as construction and decoration materials. Therefore, with the continuous improvement of people's pursuit of building aesthetics and safety, the stone processing industry has shown a huge market prospect, and the most important in stone processing The most important thing is the two aspects of technology and equipment. Among them, for stone processing equipment, the main research direction of the industry is also concentrated in the fields of stone cutting, grinding, splicing, beautification and so on. [0003] For the cutting of stone thin plates, most of the existin...

AI Technical Summary

Problems solved by technology

[0003] For the cutting of stone thin plates, most of the existing technologies adopt some problems that the degree of automation is low and automatic control cannot be realized, and it is impossible to realize precise automatic control in terms of cutting thickness and process.

In addition, in the solutions of the prior art, the thickness of the finished stone sheet is difficult to reach within 3mm, and there are also big problems in the cutting accuracy and flatness

Furthermore, in the scheme of the prior art, since the tension pressure of the cutting saw blade cannot be effectively controlled within a stable range, but when the texture of the stone is uneven, or other possible operating fluctuations occur, the pressure of the saw blade load will suddenly Increase, the cutting pressure of the saw blade will suddenly increase and decrease, and even the sudden situation of saw blade breakage will occur, which will not only seriously affect the cutting quality of stone and the service life of the saw blade, but also may cause safety accidents due to saw blade breakage
