Description

Technical Field

[0001] The utility model relates to the technical field of hard and brittle material cutting, and more specifically to a novel integral frame type diamond wire numerically controlled stone cutting machine tool. Background Art

[0002] Various types of stone are widely used in construction and house decoration, such as marble, granite, high-end luxury stone, etc. Stone comes from mines all over the world, is a non-renewable resource, and is also expensive. Currently, circular saws and reciprocating saw blades are mainly used to cut stone into panels. The thickness of the saw blade is relatively thick, and the cutting seam will be relatively wide, which will cause material waste and increase the cost of a single panel.

[0003] Diamond wire is a high-performance cutting tool used to cut hard and brittle materials. The main advantages of diamond wire include smooth cuts, high precision, high-speed cutting capability, environmentally friendly production, and the ability to cut high-quality surfaces.

[0004] The diamond wire cutting machine uses a unidirectional or reciprocating motion of the diamond wire to form a relative grinding motion between the diamond wire and the object to be cut, thereby achieving the purpose of cutting. There are similar diamond wire cutting machines on the market. The cutting area is arranged with four main rollers, which are arranged in parallel. The diamond wire is wound around the main rollers, and the wires are arranged closely to form a wire net. The cutting area can move up and down, and the wire net rotates at high speed to cut the stone.

[0005] At present, when the commonly used diamond cutting machine is used, the main rollers in the cutting area are not parallel, which will cause an angle between the roller axes, resulting in the non-parallel arrangement of the diamond wire mesh, and ultimately resulting in an uneven cut stone slab surface. At this time, more polishing processes need to be added later, which increases costs and work hours.

[0006] Therefore, in view of this, the existing structure is studied and improved, and a new integral frame diamond wire CNC stone cutting machine is provided, in order to achieve a more practical purpose. Utility Model Content

When the motor rotates, it drives the main shaft of the first bearing device 17 to rotate at a high speed, and at the same time drives the winding roller 16 to rotate at a high speed.

[0060] See also Figure 4 , Figure 5 and Figure 6 Specifically, one end of the winding roller 16 is sleeved with a first bearing device 17, and a high-precision bearing and a main shaft are arranged inside the first bearing device 17. The main shaft can rotate at high speed and is provided with an internal threaded hole.

The guide wheel 38 is provided with two pieces, and its main function is to guide the diamond wire from the winding roller 16 to the wire arrangement wheel 32, and then pass through the tensioning wheel 27, and finally wind it on the wire storage roller 24.

[0066] See also Figure 4 , Figure 7 and Figure 8 Specifically, the outer side of the overall frame 14 of the cutting knife is fixedly mounted with a wire storage shaft servo motor 22 and a wire storage shaft seat 23. The output shaft of the wire storage shaft servo motor 22 passes through the wire storage shaft seat 23 and is fixed to the wire storage roller 24.

There are two pieces in total, which are symmetrically arranged at the left and right ends of the cutting knife device 6. The wire storage shaft servo motor 22 drives the wire storage roller 24 to rotate. When cutting, the diamond wire starts to be released from the wire storage roller 24 at one end, and the wire storage roller 24 at the other end rewinds. When the diamond wire of the wire storage roller 24 that releases the wire is about to be released, the wire storage shaft servo motor 22 reverses. At this time, the wire storage roller 24 that releases the wire becomes the wire storage roller 24 that rewinds the wire. The diamond wire keeps repeating between the two wire storage rollers 24 to cut the stone.

[0067] See also Figure 4 , Figure 7 and Figure 8 Specifically, a wire storage device mounting seat 33 is fixedly installed on the side of the wire storage shaft seat 23, and a tensioning servo motor 25 is fixedly installed on the middle part of the side of the wire storage device mounting seat 33.

At the same time, the wire storage roller 24, the tensioning wheel 27, the wire arrangement wheel 32 and other key components are combined into a whole and symmetrically arranged at the left and right ends of the cutting knife device 6. The stability of the diamond wire retracting and releasing system is ensured to avoid wire breakage.

[0070] See also Figure 1 , Figure 2 , Figure 4 , Fig. 9 and Fig.10 Specifically, two stainless steel water pipe seats 41 are fixedly installed on the outer side of the cutting knife overall frame 14, and a stainless steel water pipe 42 is fixedly installed between the two stainless steel water pipe seats 41. The stainless steel water pipes 42 are distributed on the left and right sides of the stone. There are four stainless steel water pipes in total, which are arranged on both sides of the stone up and down and left and right.

[0071] A plurality of high-pressure nozzles 43 are fixedly installed on the side of the stainless steel water pipe 42. The high-pressure nozzles 43 spray out high-pressure coolant columns, which are sprayed on the side of the stone and the diamond wire mesh 15 to flush and cool the diamond wire mesh 15, so that the entire stone is surrounded by the coolant, ensuring the best cutting effect.

[0072] See also Figure 1 , Figure 2 , Figure 4 , Fig. 9 and Fig.10 Specifically, copper tube nylon seats 44 are fixed at both ends of the copper tube 45. There are two copper tubes 45, which are arranged on both sides below the diamond wire mesh 15 and installed inside the overall frame 14 of the cutting knife through the copper tube nylon seats 44. Its main function is to protect the diamond wire mesh 15 from breaking. When cutting, the hard points of the stone are different, and the diamond wire mesh 15 will form a bow shape with a bulge in the middle, and the diamond wire mesh 15 is easy to break.

[0073] The copper tube 45 is at a preset safety distance from the diamond wire mesh 15. The copper tube 45 is energized. When the bow wire mesh exceeds the set distance and touches the copper tube 45, the program detects a short circuit and slows down the feeding speed of the diamond wire mesh 15, thereby minimizing the possibility of wire breakage.

[0074] Working principle:

[0075] At the beginning of cutting, the diamond wire net 15 is completely wound around the wire storage roller 24 for unwinding, and is evenly stacked and arranged. Then, the diamond wire head passes through the tensioning wheel 27, the wire arrangement wheel 32, and the guide wheel 38, and is wound in the groove of the winding roller 16. Then, the diamond wire passes through the four winding rollers 16, is arranged and wound, and the diamond wire net 15 is formed between the four winding rollers 16. The diamond wire head passes through the guide wheel 38, the wire arrangement wheel 32, and the tensioning wheel 27 on the other side of the cutting knife device 6, and is finally wound around the wire storage roller 24 for taking up the wire, forming a closed loop.

[0076] During cutting, the winding roller servo motor 21, the wire storage shaft servo motor 22, and the wire arrangement servo motor 28 are linked together under program control. The tensioning servo motor 25 simultaneously applies tension to the diamond wire mesh 15. The four winding rollers 16 rotate at high speed at the same time, driving the diamond wire mesh 15 to move at high speed. The diamond wire starts to be unwound from the wire storage roller 24, and is given tension through the tensioning wheel 27.

[0077] Then, the wire arrangement wheel 32 moves linearly and reciprocatingly under the action of the wire arrangement servo motor 28, and the diamond wires evenly arranged on the wire storage roller 24 for wire payout are paid out one by one. The wire storage shaft servo motor 22 is operated at the same time, and the diamond wires are evenly stacked and laid on the wire storage roller 24 for wire take-up. When the diamond wires on the wire storage roller 24 for wire payout are paid out according to the set program, all the servo motors are reversed at the same time, and the wire storage roller 24 for wire payout becomes the wire storage roller 24 for wire take-up, and the original wire storage roller 24 for wire take-up becomes the wire storage roller 24 for wire payout, and wire payout begins.

[0078] After that, the diamond wire mesh 15 continuously and repeatedly rewinds and releases the wire, which is similar to the reciprocating cutting of a saw, so as to maximize the capacity of the diamond wire and better cut the stone. At the same time, the spray cooling device is started, and the coolant continuously flushes and cools the diamond wire mesh 15 to maintain continuous cutting ability. The servo reduction motor 10 provided on the side frame 5 is actuated to drive the ball screw 12 to rotate. The ball screw 12 rotates and controls the nut to make linear motion up and down, driving the movable slide 9 to move up and down along the linear guide 13. The movable slide 9 drives the cutting knife device 6 to move up and down, and the diamond wire mesh 15 moves up and down at the same time. During cutting, the stone moves to the preset position and then remains stationary. The cutting knife device 6 feeds from top to bottom to drive the diamond wire mesh 15 to cut the stone.

[0079] After the cutting is completed, the cutting blade device 6 is below the bottom of the stone material, and the stone material sheet can be easily carried without cutting the diamond wire mesh 15. The wire mesh can be repeatedly cut, saving the wire mesh cost. After the stone material sheet material is carried, the cutting blade device 6 rises above the stone material again to start the next cutting process.

[0080] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
