Three-roller downward-pressing type stone diamond wire cutting machine

Abstract

The invention relates to a three-roller downward-pressing type stone diamond wire cutting machine. The three-roller downward-pressing type stone diamond wire cutting machine comprises a machine frame,a diamond wire, a wire roller and a retracting and releasing device, the diamond wire is wound on the wire roller and connected to the retracting and releasing device, the wire roller comprises a first wire roller, a second wire roller and a third wire roller which are arranged in the horizontal direction, and the wire roller further comprises a driving mechanism used for driving an installationframe to move up and down. By adopting the technical scheme of the three-roller downward-pressing type stone diamond wire cutting machine, the driving mechanism drives the installation frame to move up and down, so that the first wire roller, the second wire roller and the third wire roller are driven to move downwards, the diamond wire walks in the retracting and releasing device and moves downwards with the wire rollers, the reciprocating cutting action is formed, the stone diamond wire is cut without lifting stone, energy consumption is saved, and saw cutting is more stable; and the wire rollers can be risen and fallen, and the diamond wire is convenient to install and adjust.

Description

technical field [0001] The invention relates to a three-roller push-down stone diamond wire cutting machine. Background technique [0002] Traditional stone blocks are processed into plates. The cutting tools currently used include saw blades, saw bands, and beaded wire saws. The cutting principle is to weld alloy diamond heads on saw blades and steel belts, or make alloy diamond heads Beads are connected in series to form a wire saw. Traditional stone machines use the above cutting tools to process stone blocks, such as bridge-type combined stone saws, marble frame saws, granite sand saws, multi-strand wire saws, band saw splitters, etc. Due to the large size of the alloy diamond cutter head, which needs to be attached to the metal substrate, the traditional cutting tool needs to have a certain thickness in order to ensure normal cutting, and cannot be thinned without limit. Therefore, a kerf of 3-10mm will be formed when cutting stone. , causing waste and pollution of sto...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned diamond wire saw machine has the following problems in use: 1. When in use, the stone is placed on the lifting mechanism, and the stone is lifted by the oil cylinder. The lifting speed and distance are poor in accuracy, which will eventually affect the stability of stone cutting and the flatness of the stone processing surface; 2. The patent uses two wire rollers and two adjustment rollers. The power needs to rely on the friction between the diamond wire and the regulating roller to drive the regulating roller to rotate. The friction between the diamond wire and the regulating roller will directly wear the regulating roller, and the structure of the regulating roller is thin and the force is large, which greatly increases the probability of diamond wire breaking a
