Description

Technical Field

[0001] This application relates to stone processing equipment, and more particularly to a lifting-type oscillating wire saw. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. A stone wire saw is a device used for cutting stone, which mainly includes a frame and a cutting assembly. The stone is moved to the bottom of the cutting assembly by a trolley, and either the cutting assembly or the stone moves up and down relative to the frame, thereby realizing the stone cutting process.

[0003] In related technologies, stone wire saws mainly employ two types of cutting: downward cutting and upward cutting. Downward cutting uses a drive device to move the cutting wire downwards, applying vertical pressure to the stone fixed on the worktable. The cutting force is generated by the high-speed movement of the cutting wire and the friction between it and the stone surface.

[0004] The core of lifting-type cutting is the active movement of the worktable. Through a hydraulic or mechanical drive system, the worktable is lifted upwards, pushing the stone into contact with the high-speed cutting line.

[0005] The two wire saw cutting methods described above have a large contact area between the cutting line and the stone, resulting in rapid heat accumulation. However, the relatively low pressure of the cutting line is not conducive to cutting hard stones such as granite, and the cutting efficiency is also low. Summary of the Invention

[0006] In view of this, this application provides a lifting-type oscillating wire saw machine, which is a rocker arm type cutting machine that can reduce the contact area between the cutting wire and the stone, increase the local pressure, thereby improving the cutting efficiency and realizing the cutting of hard stone.

[0007] To achieve the above objectives, this application employs the following technical solution:

[0008] A lifting-type oscillating wire saw, characterized in that it includes a column, a lifting platform movably connected to the column for lifting stone, a lifting mechanism installed on the column for driving the lifting platform to move up and down, a cutting assembly rotatably connected to the column via a rotating shaft for cutting the stone, and an oscillating mechanism installed on the column for driving the cutting assembly to oscillate around the rotating shaft; the cutting assembly has a cutting line, and during the oscillation process, the cutting line of the cutting assembly performs oscillating cutting on the stone.

[0009] The aforementioned lifting-type oscillating wire saw uses a lifting platform to lift the stone upwards, and the cutting assembly oscillates under the drive of the oscillating mechanism to achieve oscillating cutting. This reduces the contact area between the cutting line and the stone, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone. Furthermore, the stone itself does not need to oscillate during the cutting process, thus preventing the stone from tipping over.

[0010] In some embodiments, the cutting assembly includes a cutting frame, two or more main guide wheels rotatably connected to the cutting frame, a rotary motor for driving the main guide wheels to rotate forward and backward, and a take-up and release system mounted on the cutting frame. The cutting wire is wound around each main guide wheel to form a cutting mesh surface. Two sets of take-up and release systems are respectively connected to the two ends of the cutting wire to control the take-up and release of the cutting wire respectively.

[0011] In some embodiments, the lower middle part of the cutting frame is rotatably connected to the column via a pivot. The swing mechanism includes two sets of hydraulic cylinders mounted on the column and located on both sides of the pivot. The extension rods of the hydraulic cylinders are hinged to the cutting frame. The two sets of hydraulic cylinders drive the cutting frame to swing around the pivot in a one-to-one extension-to-retraction manner. The hydraulic cylinders on both sides can drive the cutting assembly to swing, and the hydraulic cylinders also play a role in damping and shock absorption to prevent equipment vibration.

[0012] In some embodiments, the number of hydraulic cylinders is four, located at the four corners of the cutting frame. This corner-connected configuration makes the cutting assembly more stable, less prone to vibration, and provides higher cutting precision.

[0013] In some embodiments, the cutting frame includes a lower frame and an upper frame fixedly connected to the lower frame. Both the lower and upper frames are integral structures, and the extension rod of the hydraulic cylinder is connected to the lower frame. This split structure of the cutting frame (lower and upper frames) facilitates casting, machining, and transportation. Furthermore, the hydraulic cylinders on both sides exert force on the lower frame during the lifting and retraction process. Because the lower frame is an independent integral structure, it is less prone to deformation under the force of the hydraulic cylinders. If a split structure is used, consisting of a left and right frame, deformation is more likely to occur at the middle crossbeam under the thrust of the hydraulic cylinders.

[0014] In some embodiments, the lower frame includes a first left side plate, a first right side plate, and a first front crossbeam and a first rear crossbeam integrally connected to the first left side plate and the first right side plate; the upper frame includes a second left side plate, a second right side plate, and a second front crossbeam and a second rear crossbeam integrally connected to the second left side plate and the second right side plate; two sets of hydraulic cylinders are respectively connected to the first left side plate and the first right side plate; the first front crossbeam and the second front crossbeam, as well as the first rear crossbeam and the second rear crossbeam, are connected by vertical support rods. The vertical support rods serve to provide support and reinforcement.

[0015] In some embodiments, the vertical support rod includes a lower support rod fixedly connected to a first front crossbeam or a first rear crossbeam, and an upper support rod fixedly connected to a second front crossbeam or a second rear crossbeam. The upper end of the lower support rod is provided with a first oblique flange, and the lower end of the upper support rod is provided with a second oblique flange that mates with the first oblique flange. Both the first and second oblique flanges are provided with oblong holes, and the oblique holes of the first and second oblique flanges are connected by bolts. The height of the vertical support rod can be finely adjusted by adjusting the relative positions of the oblique holes of the first and second oblique flanges. The length adjustment via the oblique flanges ensures the actual supporting function.

[0016] In some embodiments, the column includes a front column and a rear column spaced apart, the lifting platform is located between the front column and the rear column, the lifting platform is vertically and movably connected to the front column and the rear column respectively by multiple vertically arranged linear rails, and the lifting mechanism includes two sets of lead screw lifting assemblies respectively installed on the front column and the rear column.

[0017] In some embodiments, there are four main guide wheels, two of which are mounted on the lower frame and the other two are mounted on the upper frame and located directly above the two lower guide wheels. The cutting lines are spirally wound around the four main guide wheels, and the cutting lines between the two lower guide wheels form the cutting mesh surface.

[0018] In some implementations, two sets of take-up and release systems are installed on the left and right sides of the upper frame, respectively.

[0019] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0020] This application discloses a lifting-type oscillating wire saw machine. It employs a lifting platform to raise the stone, and the cutting assembly oscillates under the drive of an oscillating mechanism, thereby achieving oscillating cutting. This reduces the contact area between the cutting line and the stone, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone. Furthermore, the stone itself does not need to oscillate during the cutting process, preventing it from tipping over. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0030] See Figures 1 to 7 This application provides a lifting-type oscillating wire saw, including a column 1, a lifting platform 2 movably connected to the column 1 for lifting stone 7, a lifting mechanism 3 installed on the column 1 for driving the lifting platform 2 to move up and down, a cutting component 4 rotatably connected to the column 1 via a rotating shaft 6 for cutting the stone 7, and an oscillating mechanism 5 installed on the column 1 for driving the cutting component 4 to oscillate around the rotating shaft 6; the cutting component 4 has a cutting line 41, and during the oscillation process, the cutting component 4 performs oscillating cutting on the stone 7.

[0031] This oscillating wire saw uses a lifting platform 2 to lift the stone 7 upwards, and the cutting component 4 oscillates under the drive of the oscillating mechanism 5, thereby achieving oscillating cutting. This reduces the contact area between the cutting line 41 and the stone 7, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone 7. Furthermore, the stone 7 itself does not need to oscillate during the cutting process, preventing the stone 7 from tipping over.

[0032] The cutting assembly 4 includes a cutting frame 42, two or more main guide wheels 43 rotatably connected to the cutting frame 42, a rotary motor 44 for driving the main guide wheels 43 to rotate forward and backward, and a take-up and release system 45 installed on the cutting frame 42. The cutting wire 41 is wound around each main guide wheel 43 to form a cutting mesh surface 46. The two sets of take-up and release systems 45 are respectively connected to the two ends of the cutting wire 41 and are used to control the take-up and release of the cutting wire 41 respectively.

[0033] The lower middle part of the cutting frame 42 is rotatably connected to the column 1 via a pivot 6. The swing mechanism 5 includes two sets of hydraulic cylinders 51 mounted on the column 1 and located on both sides of the pivot 6. The extension rods of the hydraulic cylinders 51 are hinged to the cutting frame 42. The two sets of hydraulic cylinders 51 drive the cutting frame 42 to swing around the pivot 6 in a one-to-one extension-to-retraction manner. The hydraulic cylinders 51 on both sides can drive the cutting assembly 4 to swing, and the hydraulic cylinders 51 can also play a role in damping and shock absorption to prevent equipment vibration.

[0034] The hydraulic cylinders 51 are four in number and are located at the four corners of the cutting frame 42. By connecting them at the four corners, the cutting assembly 4 is more stable, less prone to vibration, and has high cutting accuracy.

[0035] The cutting frame 42 includes a lower frame 421 and an upper frame 422 fixedly connected to the lower frame 421. Both the lower frame 421 and the upper frame 422 are integral structures. The telescopic rod of the hydraulic cylinder 51 is connected to the lower frame 421. The cutting frame 42 is a separate structure consisting of the lower frame 421 and the upper frame 422, which facilitates casting, processing, and transportation. Furthermore, during the lifting and retracting process of the hydraulic cylinders 51 on both sides, a force is applied to the lower frame 421. Since the lower frame 421 is an independent integral structure, it is not easily deformed under the force of the hydraulic cylinders 51. If a separate left-right structure were used, consisting of a left frame and a right frame, deformation would easily occur at the middle crossbeam when subjected to the thrust of the hydraulic cylinders 51.

[0036] The lower frame 421 includes a first left side plate 4211, a first right side plate 4212, and a first front crossbeam 4213 and a first rear crossbeam 4214 integrally connected to the first left side plate 4211 and the first right side plate 4212; the upper frame 422 includes a second left side plate 4221, a second right side plate 4222, and a second front crossbeam 4223 and a second rear crossbeam 4224 integrally connected to the second left side plate 4221 and the second right side plate 4222; two sets of hydraulic cylinders 51 are respectively connected to the first left side plate 4211 and the first right side plate 4212; the first front crossbeam 4213 and the second front crossbeam 4223, as well as the first rear crossbeam 4214 and the second rear crossbeam 4224, are all connected by vertical support rods 423. The vertical support rods 423 serve a supporting and reinforcing function.

[0037] The vertical support rod 423 includes a lower support rod 4231 fixedly connected to the first front crossbeam 4213 or the first rear crossbeam 4214, and an upper support rod 4232 fixedly connected to the second front crossbeam 4223 or the second rear crossbeam 4224. The upper end of the lower support rod 4231 is provided with a first oblique flange 4233, and the lower end of the upper support rod 4232 is provided with a second oblique flange 4234 that mates with the first oblique flange 4233. Both the first oblique flange 4233 and the second oblique flange 4234 are provided with oblong holes. The oblique holes of the first oblique flange 4233 and the second oblique flange 4234 are connected by bolts 4235. By adjusting the relative position of the oblique holes of the first oblique flange 4233 and the second oblique flange 4234, the height of the vertical support rod 423 can be finely adjusted. The length is finely adjusted using the oblique flanges to ensure the actual supporting function.

[0038] The column 1 includes a front column 11 and a rear column 12 arranged at intervals. The lifting platform 2 is located between the front column 11 and the rear column 12. The lifting platform 2 is vertically and movably connected to the front column 11 and the rear column 12 through multiple vertically arranged linear rails. The lifting mechanism 3 includes two sets of screw lifting assemblies 31 respectively installed on the front column 11 and the rear column 12.

[0039] There are four main guide wheels 43, two of which are installed on the lower frame 421 and the other two are installed on the upper frame 422 and located directly above the two lower guide wheels 43. The cutting line 41 is spirally wound around the four main guide wheels 43, and the cutting line 41 between the two lower guide wheels 43 forms the cutting mesh surface 46.

[0040] Two sets of wire take-up and take-down systems 45 are installed on the left and right sides of the upper frame 422 respectively.

[0041] The following is a brief description of the working process and usage method of a lifting-type oscillating wire saw machine according to the above embodiments:

[0042] Stone 7 moves onto lifting platform 2 along with the trolley. Lifting mechanism 3 drives lifting platform 2 to move upward continuously, thus moving stone 7 upward as well. The main drive wheel 43 of cutting assembly 4 rotates forward and backward under the drive of motor 44, causing cutting mesh 46 to back and forth saw stone 7. Cutting frame 42, driven by four hydraulic cylinders 51, swings forward and backward around shaft 6, performing oscillating cutting. During the cutting process, the wire feeding system 45 on one side continuously releases new cutting wire 41, while the wire feeding system 45 on the other side continuously collects the old wire into a roll. After stone 7 is cut, cutting assembly 4 stops moving, and lifting platform 2 lowers and resets with stone 7.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
