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

Abstract

The invention relates to a four-roller downward-pressing-type stone diamond wire cutting machine. The four-roller downward-pressing-type stone diamond wire cutting machine comprises a rack, a diamondwire, wire rollers and a take-up and pay-off device; the diamond wire is wound on the wire rollers and connected to the take-up and pay-off device; the wire rollers comprise a first wire roller, a second wire roller, a third wire roller and a fourth wire roller which are all arranged in the horizontal direction; the first wire roller and the second wire roller are rotatably mounted on a mounting frame, and the third wire roller and the fourth wire roller are rotatably mounted on the mounting frame; the mounting frame can be mounted on the rack in an up-down moving mode; and the four-roller downward-pressing-type stone diamond wire cutting machine further comprises a driving mechanism used for driving the mounting frame to move up and down. The mounting frame is driven to move up and down through the driving mechanism, the diamond wire travels in the take-up and pay-off device and moves downwards along with all the wire rollers to form a reciprocating cutting action, stone is cut and does not need to be lifted, energy consumption is reduced, saw cutting is more stable, in addition, all the wire rollers can ascend and descend, and mounting and debugging of the diamond wire are convenient.

Description

technical field [0001] The invention relates to a four-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 ston...

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 and also Affect cutting efficiency and cutting stability; 3. The wire groove in this patent is helical. When the diamond wire is wound on the wire groove and rotates with the wire roller, the diamond wire will move axially along the spiral groove and cannot be stuck in the wire groove. Once the wire When the roller starts to rotate, the diamond wire will immediately come out of the wire groove and break the wire, and it cannot work normally at all; 4. When this patent is actually used, it is difficult to provide stable tension for the diamond wire. If the stone is pressed tightly, it will be impossible to cut the stone. At the same time, without automatic adjustment of the tension, the diamond wire will easily break during the cutting process, and it will not be able to cut the stone stably.
