Technology for cutting granite quarry stone

Abstract

The invention discloses a technology for cutting granite quarry stone. Cutting is carried out through a frame saw. A main shaft driving device, a saw frame assembly, a lifting device, a loading cart and a numerical control system are arranged on a basic installation structure of the frame saw, wherein the saw frame assembly is arranged on a rack in a sliding manner, the loading cart is arranged on the lifting device, and the numerical control system controls saw blades of the saw frame assembly to conduct feeding and controls the lifting device to be lifted. The main shaft driving device is in transmission connection with the saw frame assembly through connecting rods. When cutting is carried out, the numerical control system controls a processing feeding manner to conduct feeding in five grades, wherein the first grade is a rapid feeding, so that the granite quarry stone rapidly gets close to the saw blades; the second grade is low-speed feeding for processing, so that the saw blades cut the granite quarry stone by a certain depth at the speed lower than the conventional speed; the third grade is characterized in that the saw blades carry out cutting feeding at the normal speed; the fourth grade is characterized in that the saw blades complete final processing in a low-speed feeding manner; and the fifth grade is characterized in that the loading cart rapidly returns to the original position.

Description

technical field [0001] The invention relates to the field of stone cutting technology, in particular to a granite block cutting technology. Background technique [0002] Due to the difference in stone type, mineral composition and content, chemical composition, hardness, rock structure (mineral particle size, degree of uniformity and crystallization, density), the requirements for cutting equipment used in stone processing are also different. [0003] Granite blocks are usually cut using sand saws and diamond wire saws. However, the sand saw used for traditional cutting of granite blocks needs to be equipped with complex sand supply system, mortar spraying system and swing system, which has high cost, heavy wear, heavy maintenance workload, and relatively large secondary pollution during production; diamond wire saw Because the diameter of diamond beads is generally not less than 8mm, the yield of finished products is low, and the price of granite is expensive, and the low ...

AI Technical Summary

Problems solved by technology

However, the sand saw used for traditional cutting of granite blocks needs to be equipped with complex sand supply system, mortar spraying system and swing system, which has high cost, heavy wear, heavy maintenance workload, and relatively large secondary pollution during production; diamond wire saw Because the diameter of diamond beads is generally not less than 8mm, the yield rate of finished products is low, and the price of granite is expensive, and the low yield rate further leads to an increase in cutting costs

The traditional frame-type gang saw has a simple structure and less secondary pollution, but it can only be used to cut marble with a Mohs hardness less than 5, and cannot cut granite blocks with a Mohs hardness greater than 6 (the Mohs hardness of granite is generally 6~7)
