Description

Technical Field

[0001] This utility model relates to the field of stone cutting equipment technology, and more specifically, to a wire saw with adjustable roller distance. Background Technology

[0002] Currently, diamond wire band saws use rollers to drive the displacement of diamond wires, bringing them into contact with the stone surface. The cutting effect is achieved through friction and deformation between the diamonds fixed to the wires and the stone. The rollers are fixed to a roller frame; moving the roller frame or the stone provides the tangential force that presses the diamond wires into the stone. Typically, the distance between the rollers on the roller frame of a diamond wire band saw cannot be adjusted. When cutting shorter sections of stone, the cutting section of the diamond wire will form a large bending angle, affecting the cutting effect and, in severe cases, the quality of the finished product. Therefore, to meet the cutting needs of stones of different sizes, roller equipment with different intervals is required, which undoubtedly increases production costs and occupies production space. Existing patent: A diamond wire saw with adjustable roller distance, patent number: CN118721474A, discloses that the movable roller frame can move inside the fixed frame through the cooperation of gears and racks, adjusting the distance between the roller frames to adjust the cutting of shorter stones, reducing the cutting equipment and the space occupied by the cutting equipment. However, the existing stone cutting equipment with adjustable roller frame distance has the following problems: 1. The movable roller frame is very heavy, and the sliders extending from the upper sides of the roller frame cannot fully support it. After long-term use, it will cause deformation and squeeze the gears on the rack, causing damage to the gears and rack; 2. Although adjusting the distance between the roller frames reduces the curvature of the diamond wire, it cannot be completely eliminated in actual use. The looser diamond wire will still affect the dimensional accuracy of the stone cutting; 3. The existing patent only discloses the long fixed frame, the short fixed frame, and the roller frame, but does not disclose the stone moving mechanism. Utility Model Content

[0035] Example

[0036] Reference Figure 1 As shown, this utility model discloses a wire saw with adjustable roller distance, including a base 10, on which a lifting mechanism 20 and an adjusting mechanism 30 are provided. The lifting mechanism 20 is used to move the stone 40 up and down, and the adjusting mechanism 30 is used to adjust the distance between the two roller support brackets to achieve cutting of stone 40 of different sizes.

[0037] Reference Figure 2As shown, the lifting mechanism 20 includes a lifting bracket 202 and vertical slide rails 2011. Four support columns 201 are installed on the base 10, and the vertical slide rails 2011 are installed on the sides of the support columns 201. The four corners of the lifting bracket 202 are respectively installed on the vertical slide rails 2011. Specifically, the two vertical slide rails 2011 facing the lifting bracket 202 are inverted V-shaped, and the cross-section of the two vertical slide rails 2011 is H-shaped. Two V-shaped sliding grooves are installed on one side of the lifting bracket 202, and a C-shaped sliding sleeve is provided on the other side of the lifting bracket 202. The lifting bracket 202 can move up and down along the vertical slide rails 2011 by using the cooperation of the V-shaped sliding grooves and the inverted V-shaped slide rails. The C-shaped sliding sleeve cooperates with the H-shaped vertical slide rails 2011 to slide while preventing the lifting bracket 202 from derailing. The four support columns 201 are equipped with lead screw mechanisms 2013 and drive motors 2012 on their sides. The four corners of the lifting bracket 202 are mounted on the lead screw mechanisms 2013, and the drive motors 2012 are mounted on the lead screw mechanisms 2013. The drive motors 2012 drive the lifting bracket 202 to move up and down through the lead screw mechanisms 2013. In this embodiment, the use of four drive motors 2012 for independent control can provide greater power, allowing the stone 40 to move up and down smoothly. This, combined with the diamond wire, improves the cutting accuracy.

[0038] Reference Figure 2 As shown, the base 10 has a water collection trough below the support frame 202. During the cutting process, the stone 40 needs to be cooled with water and chipped. The water collection trough is used to collect the water falling from the stone 40 to prevent water from polluting the site.

[0039] Reference Figure 3-8As shown, the adjustment mechanism 30 includes a rectangular frame 31, a fixed roller bracket 32, and a movable roller bracket 33. The fixed roller bracket 32 ​​and the movable roller bracket 33 are movably mounted on the rectangular frame 31. Specifically, the rectangular frame 31 includes two upper fixed rods 311 and two lower fixed rods 312. The lower fixed rods 312 are provided with horizontal slide rails 3122 along their length. A rack 3121 is provided on the side of the lower fixed rods 312 near the movable roller bracket 33. Shoulders 331 protrude from both sides of the fixed roller bracket 32 ​​and the movable roller bracket 33, respectively. A slider 3311 is mounted on the shoulder 331. A drive gear 332 is provided on the movable roller bracket 33. The roller 31 is placed on the horizontal slide rail 3122. The protruding shoulders 331 on both sides can bear the weight of the fixed roller frame 32 and the movable roller frame 33. The shoulders 331 are integrally cast with the fixed roller frame 32 and the movable roller frame 33. Compared with the existing method of using the sliders 3311 extending from the upper sides of the roller frame as force points, the support of the shoulders 331 is more stable and has greater load-bearing capacity. The fixed roller frame 32 and the movable roller frame 33 are heavy, reducing deformation caused by long-term use. The movable roller frame moves along the rectangular frame 31 through the cooperation of the sliders 3311 and the horizontal slide rail 3122. The movable roller frame 33 moves through the meshing transmission of the drive gear 332 and the rack 3121 to adjust the interval distance with the fixed roller frame 32, so as to be suitable for cutting stone 40 of different sizes, avoiding the need to purchase multiple cutting equipment of different sizes and the resulting space occupation problem.

[0040] Reference Figure 3-8 As shown, the upper fixed rod 311 and the lower fixed rod 312 each have several positioning holes 3123. Specifically, positioning blocks 337, tensioning sleeves 3371, and tapered pins 3372 are respectively installed on the upper and lower sides of the fixed roller frame 32 and the movable roller frame 33. The positioning blocks 337 are installed on the fixed roller frame 32 and the movable roller frame 33. The tensioning sleeves 3371 are fixed to the positioning blocks 337. The tapered pins 3372 pass through the tensioning sleeves 3371 and cooperate with the positioning holes 3123 for fixation. When it is necessary to fix the fixed roller frame 32 and the movable roller frame 33, the tensioning sleeves 3371 are tightened by tensioning. 71. Simultaneously with positioning block 337, tapered pin 3372 is inserted into positioning hole 3123. Through the cooperation of tapered pin 3372 and positioning hole 3123, the moving roller 33 and fixed roller 32 are positioned on upper fixed rod 311 and lower fixed rod 312. Stone 40 will vibrate during the cutting process. Compared with the existing method of fixing roller 40 by using limit rod to fix roller 40 and long fixed rod, this embodiment is more secure and stable by locking tension sleeve 3371 in positioning hole 3123, avoiding the vibration during the cutting process from affecting the cutting accuracy of stone 40.

[0041] Reference Figure 3-8As shown, the back of the fixed roller frame 32 and the movable roller frame 33 are respectively movably equipped with a take-up and release roller 3362 and a tension roller 3351, with the tension roller 3351 positioned above the take-up and release roller 3362. Specifically, the fixed roller frame 32 and the movable roller frame 33 are respectively equipped with an upper roller 333 and a lower roller 334, which are arranged in parallel. The diamond wire is led out from the take-up and undo pulley 3362 of the fixed roller frame 32, passes through the tension pulley 3351, goes from the lower roller 334 of the fixed roller frame 32 to the lower roller 334 of the movable roller frame 33, then from the upper roller 333 of the movable roller frame 33 back to the upper roller 333 of the fixed roller frame 32, and returns to the lower roller 334. After multiple turns, it returns to the take-up and undo pulley 3362 of the movable roller frame 33. A second guide rail 336 and a take-up and undo motor 3361 are provided on the back of the fixed roller frame 32 and the movable roller frame 33. The take-up and undo motor 3361 is located on the second guide rail. The guide rail 336 and the take-up and undo reels 3362 are mounted on the take-up and undo motor 3361. The take-up and undo motors 3361 on both sides drive the diamond wire to wind around the upper roller 333 and the lower roller 334, thereby cutting the stone 40. The take-up and undo motor 3361 can move along the second guide rail 336 to adjust the spacing of the diamond wire wound on the upper roller 333 and the lower roller 334. When the take-up and undo motor 3361 of the fixed roller frame 32 and the movable roller frame 33 moves along the second guide rail 336 to a position close to the middle, the diamond wire of the same length can be wound more times, so the wire spacing is small. Conversely, if it moves to the opposite ends, the diamond wire of the same length is wound less times and the wire spacing is wide, so as to cut the stone 40 of different thicknesses.

[0042] Reference Figure 3-8 As shown, a first guide rail 335, a tension motor 3353, and a pressure roller 3352 are provided on the back of the fixed roller frame 32 and the movable roller frame 33. The tension motor 3353 is located on the first guide rail 335, and the tension roller 3351 and the pressure roller 3352 are mounted on the rotating shaft of the tension motor 3353. Specifically, the diamond wire drawn from the tensioning roller 3351 passes between the pressure roller 3352 and the tensioning roller 3351, wraps around the tensioning roller 3351, and returns to the lower roller 334. The tension motor 3353 drives the relative rotation of the tensioning roller 3351 and the pressure roller 3352, so that the tensioning roller 3351 rotates upward while the pressure roller 3352 presses back to tighten the diamond wire, thus tensioning the diamond wire. Although the movement of the moving roller frame 33 can reduce the bow of the diamond wire, it cannot completely eliminate it. The tensioning roller 3351 achieves the tensioning of the diamond wire on the upper roller 333 and the lower roller 334, further improving the cutting accuracy of the stone 40. Furthermore, a guide wheel 338 is provided between the take-up and release wheel 3362 and the tension wheel 3351. The guide wheel 338 serves as a transition, allowing the diamond wire drawn from the take-up and release wheel 3362 to pass between the pressure wheel 3352 and the tension wheel 3351 and then fall from the tension wheel 3351 onto the lower roller 334.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
