Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 4

[0027] A novel wire cutting machine includes a base 9 for placing stones, a frame 1 arranged above the base 9, and a cutting device 3 for cutting stones. The frame 1 includes four upright columns 11 vertically distributed at the four corners of the base 9, a bottom plate 12 erected and connected between the lower ends of the four columns 11, and a top plate 13 erected and connected between the upper ends of the four columns 11. Preferably, the base 9 can be made of reinforced concrete materials on site. When making the reinforced concrete base 9, a number of dry anchor bolts can be pre-buried in the base 9. Preferably, the bottom plate 12 and the top plate 13 are split structures, both of which are spliced ​​by multiple plates, and the adjacent plates are fastened by bolts to facilitate better transportation.

[0028] The bottom plate 12 , the top plate 13 , the base 9 and the four columns 11 form an accommodation space for placing the cutting device 3 . The cutting device 3 can move up and down in the accommodation space so that the cutting device 3 can cut the stone material arranged on the base 9 .

[0029] The cutting device 3 includes a cutting frame 31, four guide posts 32 distributed at four corners of the cutting frame 31, a cutting assembly 33 arranged on the cutting frame 31 and used for cutting stones, and a lifting mechanism for driving the cutting frame 31 to move up and down so that the cutting assembly 33 can cut stones. The cutting frame 31 is provided with four first through holes 311 for the four guide posts 32 to pass through respectively, and the four guide posts 32 are arranged in the four first through holes 311 one by one. It is worth noting that the guide posts 32 of this embodiment can adopt a bare rod guide post or a roller linear guide post. The roller linear guide post has high precision and is very smooth in operation, but the roller linear guide post is easy to get stuck after deformation, and the roller linear guide post is afraid of water ingress, and the ball is easy to rust; therefore, in this embodiment, a bare rod guide post 32 made of ultra-high molecular polyethylene is adopted, which has higher wear resistance. Other feasible methods are not described in detail here.

[0030] The lifting mechanism includes a ball screw 341 symmetrically arranged on the cutting frame 31 and located between the two guide pillars 32, and a driving motor 342 arranged on the top plate 13 and used to drive the two ball screws 341 to move synchronously. The cutting frame 31 is symmetrically provided with two second through holes 312 for the two ball screws 341 to pass through. The two ball screws 341 are rotatably arranged in the two second through holes 312 in a one-to-one correspondence and are threadedly connected to the second through holes 312. The middle part of the cutting frame 31 is provided with a channel 313 through which the stone to be cut passes when the cutting frame 31 is moved downward. The driving motor 342 of this embodiment can adopt a worm gear reducer.

[0031] The cutting assembly 33 includes guide wheels 331 arranged at the four corners of the cutting frame 31 in the horizontal direction, guide wheel motors 332 installed on the cutting frame 31 and respectively corresponding to the guide wheels 331, and a winding unit and an unwinding unit arranged on both sides of the frame 1. The output ends of each guide wheel motor 332 are respectively connected to the corresponding guide wheels 331. A rubber surface layer is laid on the guide wheel 331, and the guide wheel 331 is made of aviation aluminum material, and the rubber surface layer is made of ultra-high molecular polyethylene material. The guide wheel 331 made of lightweight aviation aluminum material reduces the lifting load of the cutting frame 31, and the outer cover is provided with a rubber surface layer of ultra-high molecular polyethylene material, which improves the wear resistance of the guide wheel 331.

[0032] Furthermore, the outer surface of the rubber surface layer is provided with a plurality of winding grooves 3311 for the diamond wires 333 to pass through. The diamond wires 333 sequentially pass around the winding grooves 3311 of the four guide wheels 331 to form a plurality of parallel cutting lines.

[0033] The winding unit and the unwinding unit are two winding devices with the same structure, each comprising a winding motor 3341, a winding wheel 3342 connected to the output shaft of the winding motor 3341, a guide wheel group 3343 and a tension control wheel group 3344. The emery wire 333 is connected to the winding motor 3341 after being guided by the winding wheel 3342, the guide wheel group 3343 and the tension control wheel group 3344, and the winding motor 3341 can reel in and unwind the wire.

[0034] The tension control wheel group 3344 includes a swing motor, a swing arm is connected to the power output end of the swing motor, and a balance wheel matching the emery wire 333 is connected to the swing arm. By controlling the swing of the swing arm, the balance wheel pulls and releases the emery wire 333 to adjust the tension of the emery wire 333.

[0035] When the emery wire 333 is wound, one end of the emery wire 333 is fixed to the winding wheel 3342 of the winding motor 3341 of the winding unit, and the other end of the emery wire 333 passes through the guide wheel group 3343 and the tension control wheel group 3344 in turn, and the emery wire 333 is coiled on the winding grooves 3311 of multiple guide wheels 331 in turn; the emery wire 333 is spirally wound between the multiple guide wheels 331; and then passes through another guide wheel group 3343, the tension control wheel group 3344, and the winding grooves 3311 of the four guide wheels 331 in turn, and then is fixed to the tension control wheel group 3344 and the guide wheel group 3343 of the unwinding unit, and then to the winding wheel 3342 of the winding motor 3341 of the unwinding unit. During the process of retracting and releasing the emery wire 333, one winding motor 3341 winds the wire, and the other winding motor 3341 releases the wire, and at the same time controls the driving motor 342 to work, so that the guide wheel 331 rotates synchronously, so that the emery wire 333 is transferred from the winding wheel 3342 of one winding motor 3341 to the winding wheel 3342 of another winding motor 3341. The emery wire 333 moves at high speed during the transfer process, and can be cut. After the emery wire 333 is completely transferred, the rotors of the two winding motors 3341 and multiple driving motors 342 are driven to reverse, and the above movement is repeated to realize the transfer of the emery wire 333 back; by driving the emery wire 333 to transfer back and forth, cutting is realized through the emery wire 333. Specifically, the guide wheel motor 332 is a servo motor.

[0036] The frame 1 is provided with a spray system, which includes a water storage tank 51 provided on the frame 1 and a water discharge tank 52 provided above the cutting frame 31. The water discharge tank 52 is provided with a plurality of through holes 521, and each through hole 521 is provided with a spray pipe (not shown in the figure). A hose for conveying water from the water storage tank to the spray pipe is connected between the water storage tank 51 and the spray pipe. The spray system can spray dust when cutting stone, and can also cool down the heat when the cutting assembly 33 cuts stone.

[0037] Preferably, it also includes a cantilever device 2 arranged on the top plate 13, the cantilever device 2 includes a support column 21 fixedly installed on the top plate 13, a first cantilever 22 rotatably connected to the support column 21, an electric hoist 23 arranged on the first cantilever 22 and moving along the length direction of the first cantilever 22, and a sling 24 installed on the electric hoist 23 and driven to rise and fall by the electric hoist 23, the first cantilever 22 extends outward to the outer periphery of the top plate 13, and the sling 24 is used to lift the roller 331 of the cutting assembly 33 to facilitate easier replacement of the roller 331.

[0038] The working principle is: the driving motor 342 drives the ball screw 341 to rotate, so that the cutting frame 31 moves up and down smoothly in the accommodating space, and the vertically arranged linear guide column 32 can further stabilize the path of the cutting frame 31 when moving up and down, ensuring that it will not shake when moving up and down, and then the stone arranged on the base 9 is planned to be cut.

[0039] By adopting the above-mentioned design scheme, the beneficial effect of the utility model is: when working, the stone is placed on the base and located in the channel of the cutting frame 31, and then the cutting frame 31 is driven by the lifting mechanism to move up and down in the accommodating space. At this time, the cutting component 33 cuts the stone; compared with the traditional method, the utility model changes the stone lifting cutting method to the cutting frame lowering cutting method, which reduces power consumption, has less jitter, has good overall stability, and improves the cutting quality of the stone.
