Stone sawing machine

Abstract

A stone sawing machine comprises a fixed frame, a movable frame, a driving wheel, a driven wheel, a ring-shaped saw blade, a orbit, a workbench and a mobile push pressure plate, wherein, lugs are formed on one side of the driving wheel and one side of the driven wheel; holding devices which clamp a downward moving saw blade are arranged on the upper surface and the lower surface of the workbench and a stone respectively; an auxiliary table board is arranged outside the working end of the workbench; the mobile push pressure plate is pushed by a transverse pushing device which comprises a lead screw, a driving device and a slide block; a cooling device is arranged on the machined surface of the stone; the saw blade comprises a saw body, rectangular teeth and blades; the rectangular teeth are formed on one side of the saw body; and two blades are welded on the two sides of the saw body. The stone sawing machine has the advantages that the difficult problem for cutting ultra-wide hard stone flakes is solved; the difficult problem for cutting ultrathin stone flakes is solved; the difficult problem of non-uniform thickness cutting is solved; the difficult problem for curved surface cutting is solved; the manufacturing cost is reduced; and manpower can be reduced, and the work efficiency can be improved by adopting the controlling of an automatic control system.

Description

technical field [0001] The invention relates to a stone processing mechanical equipment, in particular to a stone saw machine using a band saw. Background technique [0002] At present, a circular saw stone sawing machine is generally used for cutting stones. This kind of stone sawing machine has the following disadvantages: [0003] 1. The width of cutting stone depends on the radius of the circular saw. Since the cutting movement will generate strong vibration, the radius of the circular saw generally does not exceed 1000 mm. It cannot solve the difficult problem of cutting when the width exceeds 800 mm, and the huge vibration causes the processed stone flakes to be easily broken due to the great impact, and the ultra-thin stone flakes cannot be cut. [0004] 2. The disc machine relies on the rigidity of the bottom to cut the stone, and the trajectory of the cutting line deviates greatly, resulting in uneven thickness of the product. [0005] 3. The bottom of the circula...

AI Technical Summary

Problems solved by technology

It can't solve the problem of cutting slices with a width of more than 800mm, and the huge vibration causes the processed stone flakes to be easily broken due to great impact, and it cannot cut ultra-thin stone flakes

[0004] 2. The disc machine relies on the rigidity of the bottom to cut the stone, and the trajectory of the cutting line deviates greatly, resulting in uneven thickness of the product

[0005] 3. The bottom of the disc saw is very huge, and it is impossible to process stone chips other than flat surfaces.

[0006] 4. High energy consumption, the strong vibration generated during the cutting process of the circular saw leads to a lot of energy waste

[0007] 5. The waste of raw materials is serious, and the circular saw can only cut products with large thickness; the width of the cutting line is too large, which leads to serious waste of raw materials

[0008] The band saw used in processing wood has many advantages over the circular saw also used for processing wood, but because the strength of stone is much greater than that of wood and its toughness is lower than that of the base material, even if the band saw with a diamond saw blade is used to cut stone. Some problems, such as: the vibration of the saw blade, the stability of the stone, etc.
