Description

Technical Field

[0001] This application relates to stone processing equipment, and more particularly to a wire saw oscillating trolley and a stone 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 wire saw oscillating trolley and a stone wire saw. The trolley and the wire saw can realize the oscillating cutting of stone through the oscillating mechanism, thereby reducing the contact area between the cutting line and the stone, increasing 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 wire saw oscillating trolley is characterized by comprising a block trolley, a block platform for placing stone materials rotatably connected to the block trolley via a rotating shaft, and an oscillating mechanism disposed on the block trolley for driving the block platform to oscillate around the rotating shaft, wherein the block platform oscillates along with the stone materials during oscillation.

[0009] The aforementioned application describes a wire saw oscillating trolley. By adding an oscillating mechanism to the block trolley, the block table and the stone can be driven to oscillate, thereby achieving oscillating cutting of the stone. This reduces the contact area between the cutting line and the stone in the cutting assembly, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone. Moreover, by setting the oscillating mechanism on the trolley, it can be directly used on existing stone wire saws without the need for oscillating modifications to the cutting assembly, resulting in low manufacturing costs.

[0010] In some embodiments, the swaying mechanism includes two sets of hydraulic cylinders mounted on the block trolley and located on both sides of the rotating shaft. The extension rods of the hydraulic cylinders are hinged to the bottom of the block platform. When the hydraulic cylinders on both sides extend and retract, they can cause the block platform to sway around the rotating shaft. The hydraulic cylinders can provide swaying power and also have a damping and shock absorption function.

[0011] In some embodiments, guardrails are provided on both the front and rear sides of the block platform, and limiting components for supporting the left and right sides of the stone are provided on the left and right sides of the guardrails.

[0012] In some embodiments, the limiting assembly includes two threaded rods respectively fixedly installed on two guardrails and extending in the left-right direction, a limiting rod installed on the threaded rods, and multiple support units installed on the limiting rods. Each limiting rod has downward-opening latches at both its front and rear ends. The limiting rod is secured to the two threaded rods through the two latches. Two adjustable fastening nuts are threaded onto each threaded rod, clamping the limiting rod from its left and right sides. Each limiting rod has multiple threaded holes spaced apart in the front-back direction, extending through the limiting rod laterally. Each support unit includes an adjusting rod threaded into the threaded holes, a pad fixed at one end of the adjusting rod to hold the stone in place, and a square screw head fixed at the other end of the adjusting rod. Rotating the square screw head adjusts the left-right position of the pad. The limiting rods can be adjusted left-right according to the size of the stone to secure it and prevent displacement. Limiting rods are not installed during the initial cutting of the stone. They are only installed when the stone is cut to a certain depth, and they are used to hold the stone in place on both sides.

[0013] In some implementations, wedges are inserted between the railing and the stone to keep the cut stone vertical. These wedges are installed after the stone has been cut to a certain depth. By adding wedges, the stone can be held in place on both sides. A feeler gauge is also inserted into the saw cut to prevent the stone slab from tilting and breaking.

[0014] In some embodiments, the raw material trolley is equipped with a hydraulic supply device for controlling the operation of the hydraulic cylinders. The hydraulic system is integrated into the trolley, resulting in a more compact and convenient structure.

[0015] This application also provides a stone wire saw, which has the above-mentioned wire saw oscillating trolley, characterized in that: it further includes a bracket, a worktable for fixing and parking the wire saw oscillating trolley, and a cutting component installed on the bracket for cutting stone. The cutting component is disposed on the bracket and located above the worktable. At least one of the cutting component and the worktable is vertically connected to the bracket by a lifting device, so that the cutting component and the worktable can move closer to or further away from each other.

[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0017] This application adds a swaying mechanism to the block trolley, which drives the block table and the stone to sway, thereby achieving swaying cutting of the stone. This reduces the contact area between the cutting line and the stone in the cutting assembly, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone. Moreover, by setting the swaying mechanism on the trolley, it can be directly used on existing stone wire saws without the need for swaying modifications to the cutting assembly, resulting in low manufacturing costs.

Detailed Implementation

[0024] 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.

[0025] See Figures 1 to 4 This application provides a wire saw oscillating trolley, including a block trolley 1, a block platform 2 for placing stone materials rotatably connected to the block trolley 1 via a rotating shaft 3, and an oscillating mechanism disposed on the block trolley 1 for driving the block platform 2 to oscillate around the rotating shaft 3. The block platform 2 oscillates along with the stone materials during oscillation. Preferably, there are two rotating shafts 3.

[0026] This application discloses a oscillating trolley for wire saws. By adding an oscillating mechanism to the block trolley 1, the block table 2 and the stone can be driven to oscillate, thereby achieving oscillating cutting of the stone. This reduces the contact area between the cutting line and the stone in the cutting assembly, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone. Moreover, by setting the oscillating mechanism on the trolley, it can be directly used on existing stone wire saws without the need for oscillating modifications to the cutting assembly, resulting in low manufacturing costs.

[0027] The swaying mechanism includes two sets of hydraulic cylinders 4 mounted on the block trolley 1 and located on both sides of the rotating shaft 3. The extension rods 41 of the hydraulic cylinders 4 are hinged to the bottom of the block platform 2. When the hydraulic cylinders 4 on both sides extend and retract, they can cause the block platform 2 to sway around the rotating shaft 3. The hydraulic cylinders 4 can provide swaying power and also have the function of damping and absorbing shock.

[0028] The front and rear sides of the block platform 2 are equipped with guardrails 21, and the left and right sides of the guardrails 21 are respectively equipped with limiting components 22 for supporting the left and right sides of the stone.

[0029] The limiting assembly 22 includes two threaded rods 221, each fixedly mounted on one of the two guardrails 21 and extending in the left-right direction; a limiting rod 222 mounted on the threaded rods 221; and multiple support units 223 mounted on the limiting rods 222. Both ends of the limiting rods 222 have downward-opening latches 2221. The limiting rods 222 are secured to the two threaded rods 221 via the two latches 2221. Two adjustable fastening nuts 2211 are threaded onto the threaded rods 221. 11. Clamp the limiting rod 222 from both the left and right sides respectively. The limiting rod 222 is provided with multiple threaded holes 2222 spaced apart in the front-back direction, and the threaded holes pass through the limiting rod 222 from left to right. The support unit 223 includes an adjusting rod 2231 threaded into the threaded hole 2222, a pad 2232 fixedly installed at one end of the adjusting rod 2231 to hold the stone, and a square screw head 2233 fixedly installed at the other end of the adjusting rod 2231. Rotating the square screw head 2233 can adjust the left and right position of the pad 2232. The limiting rod 222 can be adjusted left and right according to the size of the stone to fix the stone and prevent the stone from swaying and shifting. The limiting rod 222 is not installed when the stone is initially cut. The limiting rod 222 is installed only when the stone is cut to a certain depth, and it holds the left and right sides of the stone.

[0030] A wedge 5 is inserted between the guardrail 21 and the stone to keep the cut stone vertical. The wedge 5 is also installed after the stone has been cut to a certain depth. By adding the wedge 5, the front and back sides of the stone can be supported. A feeler gauge is also inserted into the saw cut to prevent the stone slab from tilting and breaking.

[0031] The raw material trolley 1 is equipped with a hydraulic supply device 11 for controlling the operation of the hydraulic cylinder 4. The hydraulic system is integrated into the trolley, making the structure more compact and convenient.

[0032] See Figure 5 This diagram illustrates the usage state of another embodiment of the present application. This embodiment provides a stone wire saw with the aforementioned wire saw oscillating trolley, and also includes a support, a worktable for fixing and parking the wire saw oscillating trolley, and a cutting assembly mounted on the support for cutting stone. The cutting assembly is disposed on the support and located above the worktable. At least one of the cutting assembly and the worktable is vertically and vertically connected to the support via a lifting device, so that the cutting assembly and the worktable can move closer to or further away from each other.

[0033] During operation, the lifting device brings the cutting assembly closer to the worktable, while the hydraulic cylinders 4 on both sides extend and retract, causing the block table 2 to oscillate around the pivot 3, thus enabling the cutting assembly to perform oscillating cutting on the stone on the block table 2. After cutting is completed, the oscillation stops, and the lifting device moves the cutting assembly and worktable away from each other to reset.

[0034] 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.
