Description

Technical Field

[0001] The present invention relates to the technical field of stone cutting, and in particular to a stone wire cutting system and a cutting method. Background Art

[0002] Diamond wire is a cutting tool made of electroplated diamond on the outer layer of metal steel wire. Currently, diamond wire cutting is widely used in cutting photovoltaic silicon wafers, sapphire, graphite, magnetic materials and other industries. The above fields where diamond wire cutting has been popularized have processing objects of artificial materials with uniform materials, unified specifications and small sizes. The length, width and height of the cutting object are generally less than 500mm*500mm*300mm, and the cross-sectional area of ​​the cut product is less than 300mm*300mm. The diameter of the diamond wire generally used ranges from 0.03 to 0.2mm, and the working tension of diamond wires of different wire diameters ranges from 3 to 30N. The cutting stroke is generally less than 400mm.

[0003] In the process of stone processing, the most important step is the cutting of rough materials. Traditional rough stone cutting generally uses saw blades, rope saws, band saws and other materials with alloy blades for processing. Traditional cutting has several disadvantages, such as large cutting kerf, waste of stone, large vibration during cutting, easy board pulling, etc. Due to the structural characteristics of these saw blades, the cemented carbide must have a certain thickness, so that the traditional tools will form saw kerfs ranging from 3 to 10 mm in the process of cutting stone; in addition, during the processing, the cemented carbide tool and the stone are in rigid contact. The stone is peeled off by external force, which will produce large vibrations and easily cause the stone to break during the processing. Generally, only rough boards with a thickness of more than 10 mm can be cut. With the influence of various factors such as rising labor costs, higher environmental protection requirements, and increased industry competitiveness, a new cutting process and method are urgently needed to meet the needs of rough material cutting.

[0004] Under this situation, we fully draw on the application experience of diamond wire cutting in other fields, use diamond wire as a cutting tool, and develop a cutting system suitable for the stone industry to replace traditional cutting methods to complete stone rough material cutting.

[0041] Stone wire cutting equipment has high requirements for precision, and there are many factors that affect the cutting quality. The inventor of the present invention has found that the diamond wire of the winding part is affected by the stone powder cut, which will cause problems such as shaking or jamming during the stone cutting process, thereby affecting the consistency of the cutting depth of each cutting part, and further affecting the cutting quality. Therefore, the embodiment of the present invention provides a stone wire cutting system with an improved design for the winding part to address the problem that the wire saw process is prone to shaking, jamming and other phenomena that affect the cutting quality.

[0042] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0043] Combination Figure 1-Figure 9As shown, the embodiment of the present invention provides a stone wire cutting system, including a cutting part 1, a lifting part 2, a winding part 3 and a control module 6. The lifting part 2 is connected to the ground foundation, so as to serve as the reference and installation platform of the entire stone wire cutting system. A lifting platform support is arranged on the ground foundation. At the same time, the lifting part 2 drives the lifting platform to lift the stone block 12 in the vertical direction through the combination of the lead screw, the flat guide rail and the V-shaped guide rail, so as to achieve the rise or fall of the stone block 12. The cutting part 1 and the lifting part 2 are connected to each other in the vertical direction. The cutting part 1 is provided with a roller 10 for driving the diamond wire 9 to move at high speed. The cutting part 1 is provided with a winding part 3 on both sides of the direction where the stone block 12 enters the lifting part 2. The winding parts 3 on both sides cooperate with each other to achieve the reciprocating motion of the diamond wire 9, so as to complete the cutting of the stone block 12. The control module 6 is connected to each component respectively, and the cutting of the stone block 12 is achieved by controlling the operation of each component.

[0044] Specifically, the winding part 3 includes: a winding assembly 31, a wiring assembly 33, a wire arrangement assembly 32, a tension assembly 34 and a wire outlet assembly 36. The winding assembly 31, the wire arrangement assembly 32, the tension assembly 34, the wiring assembly 33 and the wire outlet assembly 36 are arranged in sequence along the transmission direction of the diamond wire 9. The diamond wire 9 starts to be wound on the winding assembly 31 in the winding part 3 on one side, and successively bypasses the wire arrangement assembly 32, the tension assembly 34, and the wiring assembly 33, and then passes through the wire outlet assembly 36. The passing position is on one side of the width direction of the stone blank 12, and then spirally wound on the four rollers 10 provided in the cutting part 1, and then penetrates from the wire outlet assembly 36 of the winding part 3 on the other side of the width direction of the stone blank 12, and successively bypasses the wiring assembly 33, the tension assembly 34, and the wire arrangement assembly 32 on the other side, and then is wound on the winding assembly 31 to complete the layout of the diamond wire net. The distance between two adjacent diamond wires 9 in the diamond wire mesh is the thickness of the rough board to be cut, and can be freely adjusted according to production requirements.

[0045] Furthermore, a sliding guide rail and a driving component are provided on the back plate 11 of the winding part. The sliding guide rail is arranged in a direction parallel to the stone cutting width. The wiring assembly 33 is installed on the sliding guide rail, and the position of the wiring assembly 33 on the sliding guide rail is adjusted by the driving component to adapt to the cutting of stone blocks 12 of different widths.

[0046] In order to achieve stable and smooth transmission of the diamond wire on the winding part, guide wheels 35 are provided on the wiring assembly 33, the cable assembly 32, and the tension assembly 34 (there are four guide wheels 35 in total). Figure 5As shown, optionally, a V-shaped annular groove is provided on the outer cylindrical rubber layer of the guide wheel to stabilize the position of the diamond wire 9 and prevent it from swinging and shifting. A guide wheel 35 is provided on each of the cable assembly 32 and the tension assembly 34, and two guide wheels are provided on the wiring assembly 33, which are respectively a first guide wheel 331 and a second guide wheel 332. The first guide wheel 331 and the guide wheels 35 on the cable assembly 32 and the tension assembly 34 are basically in the same plane (for example, coplanar or parallel, ideally coplanar), and are basically parallel to the winding part back plate 11; and the other guide wheel (the second guide wheel 332) is perpendicular to the winding part back plate 11, and along the arrangement direction of the diamond wire 9, the second guide wheel 332 is provided between the first guide wheel 331 and the outlet assembly 36, and the direction of the diamond wire 9 wound on the first guide wheel 331 is adjusted by the second guide wheel 332. Optionally, the V-shaped annular groove of the second guide wheel 332 is just tangent to the diamond wire 9 led out from the first guide wheel 331, that is, compared with the prior art in which a single guide wheel is tilted and arranged to pass through the wire outlet (i.e., the wire opening 3621 hereinafter), the present invention switches the diamond wire 9 from the horizontal transmission direction to the vertical transmission direction through the cooperation of the first guide wheel 331 and the second guide wheel 332. At the same time, the V-shaped annular groove of the second guide wheel can also further limit the diamond wire 9 to prevent the diamond wire from jittering in the horizontal direction such as left-right deviation during the cutting of the rough material. It should be noted that the first guide wheel 331 is parallel to the back plate 11 of the winding part, which means that the plane where the wheel body of the first guide wheel 331 is located is arranged along the horizontal direction or close to the horizontal direction, and the second guide wheel 332 is perpendicular to the back plate 11 of the winding part, which means that the plane where the wheel body of the second guide wheel 332 is located is arranged along the vertical direction or close to the vertical direction.

[0047] Furthermore, combined with Figure 1 as well as Figure 6-Figure 8As shown, the wire outlet assembly 36 includes a blocking structure (not shown in the figure), and the blocking structure is provided with a plurality of wire openings 3621 spaced apart along the stone cutting width direction, and the wire openings 3621 are used for the diamond wire 9 led out from the second guide wheel 332 to pass through, that is, the second guide wheel 332 is aligned with the wire opening 3621, and the diamond wire 9 led out from the second guide wheel 332 passes through the wire opening 3621 in a straight line, and a back plate opening (that is, the winding portion back plate opening 111) is provided on the winding portion back plate 11, and the diamond wire 9 passes through the back plate opening after passing through the wire opening 3621 to realize wiring on the roller. The inventor discovered that during the rough material cutting process, with the reciprocating motion of the diamond wire, rough stone powder is sometimes carried out and accumulated in the annular groove of the guide wheel, especially the second guide wheel that is closest to the rough material. As the cutting continues for a long time, the stone powder will accumulate more and more, causing the diamond wire to wear the annular groove of the second guide wheel when the diamond wire runs at high speed, which in turn causes the annular groove of the guide wheel to be unable to effectively limit the diamond wire. The wear of the guide wheel will in turn aggravate the wear, shaking, and jamming of the diamond wire. The present invention can effectively block the stone powder by providing a blocking structure, and can prevent the occurrence of problems such as shaking and jamming during diamond wire cutting. Therefore, in the embodiment of the present invention, a blocking structure is provided, and the distance between two adjacent wire openings is greater than the maximum movable distance of the blocking structure along the stone cutting width direction (i.e. Figure 6 The distance L shown in the figure) can ensure that no matter how the blocking structure moves, the opening 111 of the back plate of the winding part can be blocked, wherein the distance between the openings 111 of the back plate of the winding part is Figure 6 As shown in the figure, the position of the second guide wheel 332 can be adjusted according to the different widths of the stone blocks, and the position of the wire opening 3621 can be adjusted accordingly to ensure the passage of the diamond wire. Since the spacing between two adjacent wire openings 3621 is greater than the distance L, it can be ensured that the entire blocking structure covers the width range d of the opening 111 of the back plate of the winding part, thereby solving the problem of impurities such as stone powder generated during stone cutting scattering onto components such as guide wheels, causing jitter and jamming of the diamond wire 9 during transmission.

[0048] Alternatively, if Figure 6 and Figure 7The blocking structure includes a slot structure 361, a sealing plate 362, a sealing rubber ring 363 and a clamping plate 364. The slot structure 361 is connected to the winding part back plate 11, and a slot is formed between the slot structure 361 and the winding part back plate 11. The clamping plate 364 is rotatably mounted on the winding part back plate 11 through a five-star handle 365. The screw head of the five-star handle 365 is a hexagonal structure, which is convenient for directly twisting the sealing plate 362 by hand. The sealing rubber ring 363 is arranged between the sealing plate 362 and the back plate 11 of the winding part. The sealing plate 362 is installed in the card slot and fixed by the card plate 364. A plurality of wire openings 3621 serving as diamond wire passages are arranged on the sealing plate 362 at intervals along the width direction of the stone cutting. The distance between two adjacent wire openings 3621 is greater than the maximum movable distance L of the sealing plate 362 along the width direction of the stone cutting (that is, the distance between the end of the sealing plate and the opening 111 of the back plate of the winding part). In this way, the width range of the entire winding back plate opening can be covered, thereby preventing stone powder from splashing into the inside of the winding part during stone cutting, thereby causing the diamond wire to shake, get stuck, and other problems.

[0049] Optionally, continue to Figure 8 The wire opening 3621 is a U-shaped structure, and the length-to-width ratio of the U-shaped opening is greater than 5:1 and less than or equal to 10:1, wherein the length direction is the vertical direction and the width direction is the horizontal direction. It can be understood that the increase in the length-to-width ratio will improve the shielding and sealing effect of the stone powder to a certain extent, but a too large length-to-width ratio is not conducive to the passing and installation of the diamond wire 9, so it should be controlled within an appropriate range.

[0050] The stone wire cutting system provided by the embodiment of the present invention can adjust the arrangement position of the diamond wire 9 and the width of the entire wire network according to the width and specific position of the stone block 12 by setting a wiring component 33 with adjustable position, and adjust the direction of the diamond wire 9 in cooperation with two guide wheels in different directions, which is beneficial to improving the transmission stability of the diamond wire 9, thereby reducing the problem of wire jitter; at the same time, in cooperation with the wire outlet mode of the guide wheel, on the basis of small jitter of the diamond wire 9, a blocking structure of the wire opening is used to block the back plate 11 of the winding part without affecting the transmission of the diamond wire 9. During the online cutting movement, the wear effect of stone powder on the guide wheel and the wear effect of the diamond wire 9 in the transmission process can be reduced, thereby avoiding the operation jitter and jamming problems in the cutting process, ensuring the smooth operation of the diamond wire 9, and helping to improve the cutting quality of the stone.

[0051] In some embodiments, as shown in FIG. 9 , the winding assembly 31 includes: a fixed frame 311 , a rolling bearing, a winding roller 312 , a floating short shaft 315 , a fixed pull rod 314 , a locking nut 316 and a fixed short shaft 313 .

[0052] Specifically, two bearing supports are disposed opposite to each other at both ends of the fixed frame 311, and rolling bearings are disposed in corresponding bearing supports respectively. One end of the floating short shaft 315 is mounted in cooperation with the bearing in one of the bearing supports, and the other end of the floating short shaft 315 is mounted in cooperation with one end of the winding roller 312 by using a conical surface. One end of the fixed short shaft 313 is mounted in cooperation with the bearing in the other bearing support, and the other end of the fixed short shaft 313 is mounted in cooperation with the other end of the winding roller 312 by using a conical surface. The fixed pull rod 314 is located in the winding roller 312 and arranged along the rotation center line of the winding roller 312, one end of the fixed pull rod 314 is connected to the fixed short shaft 313, and the other end of the fixed pull rod 314 passes through the floating short shaft 315 and is connected to the locking nut 316.

[0053] The embodiment of the present invention adopts the above-mentioned winding assembly 31, so that the installation and disassembly of the winding roller 312 are more convenient and quick, and the positioning accuracy of the conical surface is high, ensuring that the winding assembly 31 runs more stably at high speed, and the diamond wire 9 on the winding roller 312 is arranged more evenly, further reducing the impact of the jitter of the diamond wire 9 on the cutting.

[0054] Optionally, the roller 10 has a non-metallic adhesive layer on its surface, such as Figure 4 As shown, a plurality of V-shaped annular grooves are provided on the rubber layer on the outer cylindrical surface of the roller 10, which stabilize the position of the diamond wire 9 to prevent swinging and position displacement, and at the same time utilize the friction between the diamond wire 9 and the rubber layer to drive the diamond wire 9 to move at high speed.

[0055] In some embodiments, the stone wire cutting system further comprises: an inserting mechanism ( Figure 1 The inserting plate mechanism is located between the cutting portion 1 and the lifting portion 2, and a plurality of rows of inserting plates are arranged on the inserting plate mechanism. The number of inserting plates can correspond to the corresponding cutting paths. The inserting plates can be fixed on the inserting plate support plate by a clamping mechanism, and the lifting and lowering of the entire inserting plate mechanism can be realized by lifting and lowering the inserting plate support plate.

[0056] Specifically, the two ends of the insert mechanism are respectively connected to the two sides of the cutting part 1 in a liftable manner, and are used to press the insert into the corresponding cutting path after the stone is cut into a cutting path of a preset depth, and the insert mechanism and the lifting part 2 rise synchronously as the cutting path depth increases.

[0057] Optionally, the inserting mechanism may also be a flipping mechanism, which can be flipped to a vertical direction and moved to one side of the cutting part 1 when not in use, so as not to affect the normal operation of the cutting part 1.

[0058] In some embodiments, the stone wire cutting system also includes: a bearing temperature detection module 8 and an alarm module; the control module 6 is electrically connected to the bearing temperature detection module 8 and the alarm module respectively, for obtaining the real-time temperature of the bearing, and controlling the alarm module to send an alarm message when the real-time temperature of the bearing is higher than a preset threshold value, so as to avoid the bearing from rotating under high temperature conditions, thereby further reducing the operation jitter problem of the diamond wire 9.

[0059] Optionally, a cooling mechanism 4 is provided at the top and bottom of the cutting part 1 to provide water to wash the stone block 12 during the rough material cutting, and promptly remove the stone powder generated by the cutting, and also to cool the diamond wire 9 and the cut rough board. In addition, a step and a protection assembly 5 interconnected with the lifting part 2 are provided at the periphery of the cutting part 1 as a pedestrian passage and an operating platform, on which an operating table and a control cabinet of a control module 6 are also provided.

[0060] Optionally, the stone wire cutting system further comprises: a lifting lubrication module 7, which is used to lubricate the lifting part 2 to ensure the stability of the lifting of the stone block 12, thereby facilitating the improvement of the cutting quality.

[0063] Optionally, the stone wire cutting system also includes: a diamond wire loss detection device, which is used to detect the loss of the diamond wire 9 in use online. The control module 6 is electrically connected to the diamond wire loss detection device, and is used to adjust the wire retraction amount or the speed of the lifting part 2 in real time according to the loss of the diamond wire 9, so as to avoid wire breakage or cutting position deviation caused by excessive tension, thereby helping to improve the cutting quality of the stone.

[0065] S100, controlling the lifting part 2 to rise to lift the stone block 12 to a preset position.

[0066] Specifically, the stone block 12 is fixed by the fixing frame 311, and the stone block 12 and the fixing frame 311 are lifted as a whole by the lifting part 2, and stop after reaching a preset position (lower than the lowest position of the diamond wire 9 on the roller 10).

[0067] S200, adjusting the position of the wiring assembly 33 according to the width of the stone block 12, thereby determining the wiring width of the diamond wire mesh.

[0068] Specifically, stone blocks 12 of different widths correspond to different cutting widths. Before cutting, the position of the wiring assembly 33 needs to be adjusted to adjust the position of the diamond wire 9, so that the diamond wire 9 can pass through the wire opening 3621 from the second guide wheel 332 and enter the cutting part 1, thereby avoiding the jitter problem caused by the offset transmission of the diamond wire 9.

[0069] S300 , arranging a diamond wire mesh and using the wire outlet assembly 36 to shield the winding portion back plate 11 , and the diamond wire 9 passes through the wire opening 3621 and is aligned with the second guide wheel 332 of the wiring assembly 33 .

[0070] It should be noted that by adjusting the position of the blocking structure along the stone cutting width direction, the position of the wire opening 3621 is aligned with the V-shaped ring groove of the second guide wheel 332, thereby avoiding the problem of the diamond wire 9 being stuck or jittered.

[0071] S400, controlling the lifting part 2 to continue to rise, so that the diamond wire 9 contacts the stone block 12 and cuts it.

[0072] Optionally, step S400 also includes:

[0073] During the cutting process, the tension of the diamond wire 9 and the loss of the diamond wire 9 are monitored in real time to avoid problems such as wire breakage or cutting position deviation caused by excessive tension or loss of the diamond wire 9, thereby facilitating further improving the cutting quality.

[0074] Optionally, between step S300 and step S400, the following steps are further included:

[0075] The cooling mechanism 4, the bearing temperature control module 6 and the lifting and lubrication unit are controlled to start, thereby ensuring the normal operation of the system and the cutting quality.

[0076] The stone wire cutting method provided in the embodiment of the present invention is based on the stone cutting system of the aforementioned embodiment. By setting a wiring assembly 33 with adjustable position, the arrangement position of the diamond wire 9 and the width of the entire wire network can be adjusted according to the width and specific position of the stone block 12, and the direction of the diamond wire 9 is adjusted in conjunction with two guide wheels in different directions, which is beneficial to improving the transmission stability of the diamond wire 9, thereby reducing the problem of wire jitter. At the same time, in conjunction with the wire output method of the guide wheel, on the basis of small jitter of the diamond wire 9, an open sealing plate 362 structure is used for sealing. During the online cutting movement, the influence of stone powder on the transmission process of the diamond wire 9 can be reduced, thereby avoiding the problems of operation jamming and jittering during the cutting process, further improving the smooth operation of the diamond wire 9, and then helping to improve the cutting quality of the stone.
