Description

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

Technical Field

The utility model relates to a four rollers push down formula stone material buddha's warrior attendant wire cut electrical discharge machining.

Background

The cutting tool that traditional stone quarry stone processed into panel adopted at present has saw bit, saw area, string of beads rope saw, and its cutting principle all is welding alloy diamond tool bit on saw bit, steel band, perhaps makes alloy diamond tool bit string of beads establish ties into the rope saw, and traditional stone machine uses above cutting tool to process the stone quarry stone, for example bridge type combination stone sawing machine, marble frame saw, granite sand saw, stranded rope sawing machine, band saw cut open machine etc.. Because the alloy diamond tool bit is large in volume and needs to be attached to a metal substrate, the traditional cutting tool needs to have certain thickness in order to ensure normal cutting and cannot be thinned without limit, and therefore, a saw gap of 3-10mm can be formed when the stone is cut, and waste and pollution of the stone are caused. The defects of large saw kerf, large noise, large occupied area of the equipment, high energy consumption and large pollution of the traditional stone processing equipment are caused. For this reason, in the chinese utility model patent of the bulletin number CN 209738022U, entitled "electroplate diamond wire saw for stone material", disclose an electroplate diamond wire saw for stone material, including diamond wire, line roller, winding power device, receipts winding device, the line roller is two, and the interval sets up in the hoist mechanism top side by side, and diamond wire is around establishing on two line rollers, receives winding device is two, sets up respectively in two line roller outsides, receives winding device including receiving and releasing the reel, receive and release, the line roller all is connected with winding power device.

The diamond wire saw machine as described above has the following problems in use: 1. when the stone cutting machine is used, the stone is placed on the lifting mechanism, the stone is lifted through the oil cylinder, the weight of the stone block is large, the oil cylinder is easy to release pressure, the lifting speed and distance are difficult to control accurately, the accuracy is poor, and the stability in stone cutting and the flatness of a processed stone surface are influenced finally; 2. the device adopts a structure of two wire rollers and two adjusting rollers, the two adjusting rollers do not have power, the adjusting rollers are driven to rotate by the friction force of the diamond wires and the adjusting rollers, the friction between the diamond wires and the adjusting rollers directly abrades the adjusting rollers, and the single-layer thickness of the adjusting roller structure is large in stress, so that the wire breakage probability of the diamond wires is greatly increased, and the cutting efficiency and the cutting stability are also influenced; 3. in the patent, the wire groove is spiral, when the diamond wire is wound on the wire groove and rotates along with the wire roller, the diamond wire can axially move along the spiral wire groove and cannot be clamped in the wire groove, once the wire roller starts to rotate, the diamond wire can immediately fall out of the wire groove and break, and the wire cannot normally work at all; 4. this patent is when the in-service use, is difficult to provide stable tension for the diamond wire, and the diamond wire that does not have stable tension will not compress tightly the stone material just also can't cut the stone material in the course of the work, simultaneously, does not carry out automatically regulated to tension, and the diamond wire will appear the broken string very easily in cutting process, just also can't cut the stone material steadily.
