Description

Technical Field

[0001] The invention relates to the technical field of stone cutting equipment, in particular to a wire saw with adjustable roller distance. Background Art

[0002] At present, diamond wire saws use rollers to drive the diamond wire to move and contact the surface of the stone. The diamonds fixed on the diamond wire rub against the stone and deform to achieve the cutting effect. The rollers are fixed on the roller frame, and the moving roller frame or the moving stone provides the tangential force for the diamond wire to press into the stone. Normally, the distance between the rollers on the roller frame of the diamond wire saw cannot be adjusted. When cutting stones of shorter lengths, the cutting section of the diamond wire will form a large bending angle, affecting the stone cutting effect. In severe cases, it affects the quality of the finished product. Therefore, in order to meet the cutting of stones of different sizes, roller equipment with different spacing distances is required for cutting, which undoubtedly increases production costs and occupies production space. Existing patent: A diamond wire gang saw with adjustable roller distance, patent number: CN118721474A, discloses that the movable roller frame can move inside the fixed frame through the cooperation of the gear and the rack, adjust the distance between the roller frames, adjust the cutting of shorter stones, and reduce the space occupied by the cutting equipment and the cutting equipment. However, the existing stone and individual equipment with adjustable distance between roller frames have the following problems: 1. The overall weight of the movable roller frame is very heavy, and it cannot be fully supported by relying solely on the sliders extending from both sides of the upper end of the roller frame as support. After long-term use, it will cause deformation and extrusion of the gear on the rack, causing damage to the gear and rack; 2. Although the adjustment of the distance between the roller frames reduces the curvature of the diamond wire, it cannot be completely eliminated in actual use. The loose diamond wire will still affect the dimensional accuracy of stone cutting; 3. The existing patent only discloses the long fixed frame, the short fixed frame and the roller frame, and does not disclose the movable stone mechanism. Summary of the invention

[0035] Example

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

[0037] Reference Figure 2As shown, the lifting mechanism 20 includes a lifting bracket 202 and a vertical slide rail 2011, four support columns 201 are installed on the base 10, the vertical slide rail 2011 is installed on the side of the support column 201, and the four corners of the lifting bracket 202 are respectively installed on the vertical slide rail 2011; specifically, the two vertical slide rails 2011 are inverted V-shaped on one side facing the lifting bracket 202, and the cross-section of the two vertical slide rails 2011 is H-shaped, two V-shaped slide grooves are installed on one side of the lifting bracket 202, and a C-shaped sliding sleeve is arranged on the other side of the lifting bracket 202, and the V-shaped sliding groove and the inverted V-shaped sliding rail are used in a manner of cooperating to realize that the lifting bracket 202 can move up and down along the vertical slide rail 2011, and the C-shaped sliding sleeve and the H-shaped vertical slide rail 2011 are used to cooperate in sliding to prevent the lifting bracket 202 from derailing. A screw mechanism 2013 and a driving motor 2012 are arranged on the sides of the four supporting columns 201, the four corners of the lifting bracket 202 are installed on the screw mechanism 2013, and the driving motor 2012 is installed on the screw mechanism 2013. The driving motor 2012 drives the lifting bracket 202 to move up and down through the screw mechanism 2013. In this embodiment, four driving motors 2012 are independently controlled to provide greater power, so that the stone 40 can move up and down smoothly to cooperate with the diamond wire, thereby improving the cutting accuracy.

[0038] Reference Figure 2 As shown, the base 10 is provided with a water collecting trough below the lifting bracket 202. The stone 40 needs to be watered for cooling and chip removal during the cutting process. The water collecting trough is used to collect water dropped by 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 frame 32 and a movable roller frame 33. The fixed roller frame 32 and the movable roller frame 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 the length direction. A rack 3121 is provided on one side of the lower fixed rods 312 close to the movable roller frame 33. Both sides of the fixed roller frame 32 and the movable roller frame 33 are protruded to form shoulders 331, and a slider 3311 is installed on the shoulder 331. The movable roller frame 33 is provided with a driving gear 332. The support of the fixed roller frame 32 and the movable roller frame 33 is placed on the horizontal slide rail 3122, and the shoulders 331 protruding on both sides can bear the weight of the fixed roller frame 32 and the movable roller frame 33. The shoulders 331, the fixed roller frame 32 and the movable roller frame 33 are integrally cast. Compared with the existing use of the sliders 3311 extending from both sides of the upper end of the roller frame as the force point, the support of the shoulders 331 is more stable and has a greater bearing capacity. The fixed roller frame 32 and the movable roller frame 33 have a large weight, which reduces the deformation caused by long-term use. Then, the movable roller frame is moved along the rectangular frame 31 by the cooperation of the slider 3311 and the horizontal slide rail 3122. The movable roller frame 33 is moved by the meshing transmission cooperation of the driving gear 332 and the rack 3121 to adjust the interval distance with the fixed roller frame 32, so as to be suitable for cutting stones 40 of different sizes, avoiding the problem of purchasing cutting equipment of multiple sizes and the space occupied.

[0040] Reference Figure 3-8 As shown, the upper fixed rod 311 and the lower fixed rod 312 are respectively provided with a plurality of positioning holes 3123. Specifically, positioning blocks 337, tension 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 block 337 is installed on the fixed roller frame 32 and the movable roller frame 33. The tension sleeve 3371 is fixed to the positioning block 337. The tapered pin 3372 passes through the tension sleeve 3371 and is fixed in cooperation with the positioning hole 3123. When the fixed roller frame 32 and the movable roller frame 33 need to be fixed, the tension sleeve 3371 is tensioned and locked. 71 inserts the tapered pin 3372 into the positioning hole 3123 while positioning the block 337, and the movable roller frame 33 and the fixed roller frame 32 are positioned on the upper fixed rod 311 and the lower fixed rod 312 through the cooperation of the tapered pin 3372 and the positioning hole 3123. The stone 40 will vibrate during the cutting process. Compared with the existing method of fixing the roller frame and the long fixed frame by a limit rod, the present embodiment is more secure and stable by locking the tensioning sleeve 3371 in the positioning hole 3123, thereby preventing the vibration during the cutting process from affecting the cutting accuracy of the stone 40.

[0041] Reference Figure 3-8As shown, the backs of the fixed roller frame 32 and the movable roller frame 33 are respectively movably provided with a pay-off and pay-off wheel 3362 and a tensioning wheel 3351 , and the tensioning wheel 3351 is arranged above the pay-off and pay-off wheel 3362 . Specifically, the fixed roller frame 32 and the movable roller frame 33 are respectively provided with an upper roller 333 and a lower roller 334, and the upper roller 333 and the lower roller 334 are arranged in parallel. The diamond wire is led out from the pay-off and take-up wheel 3362 of the fixed roller frame 32, passes through the tensioning wheel 3351 from the lower roller 334 of the fixed roller frame 32 to the lower roller 334 of the movable roller frame 33, and then from the upper roller 333 of the movable roller frame 33 to the upper roller 333 of the fixed roller frame 32 back to the lower roller 334, and after multiple turns of winding, returns to the pay-off and take-up wheel 3362 of the movable roller frame 33. The fixed roller frame 32 and the movable roller frame 33 are provided with a second guide rail 336 and a pay-off and take-up motor 3361 on the back, and the pay-off and take-up motor 3361 is arranged on the second guide rail. Rail 336, the pay-off and take-up wheel 3362 is installed on the pay-off and take-up motor 3361, and the pay-off and take-up motor 3361 on both sides drives the diamond wire to be wound around the upper roller 333 and the lower roller 334 to achieve cutting of the stone 40. The pay-off and take-up motor 3361 can move along the second guide rail 336 to adjust the spacing of the diamond wire wound around the upper roller 333 and the lower roller 334. When the pay-off and take-up 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 same length of diamond wire can be wound a few more times, so the wire spacing is small. On the contrary, if it moves toward opposite ends, the same length of diamond wire can be wound around fewer turns and the wire spacing is wide, so as to achieve cutting of stones 40 of different thicknesses.

[0042] Reference Figure 3-8 As shown, a first guide rail 335, a tension motor 3353 and a pressure wheel 3352 are arranged on the back of the fixed roller frame 32 and the movable roller frame 33. The tension motor 3353 is arranged on the first guide rail 335, and the tension wheel 3351 and the pressure wheel 3352 are installed on the rotating shaft of the tension motor 3353. Specifically, the diamond wire led out from the tensioning wheel 3351 passes between the pressure wheel 3352 and the tensioning wheel 3351 and is wrapped around the tensioning wheel 3351 to return to the lower roller 334. The tension motor 3353 drives the tensioning wheel 3351 and the pressure wheel 3352 to rotate relative to each other, so that the tensioning wheel 3351 rotates upward while the pressure wheel 3352 presses the diamond wire back, thereby tensioning the diamond wire. Although the movement of the movable roller frame 33 can reduce the wire bow amplitude of the diamond wire, it cannot completely eliminate it. The tensioning wheel 3351 is used to tension the diamond wire on the upper roller 333 and the lower roller 334, thereby further improving the cutting accuracy of the stone 40. Furthermore, a guide wheel 338 is further arranged between the pay-off and pay-off wheel 3362 and the tensioning wheel 3351 , and the guide wheel 338 serves as a transition, so that the diamond wire led out from the pay-off and pay-off wheel 3362 can pass between the pressure wheel 3352 and the tensioning wheel 3351 and go around the tensioning wheel 3351 to fall onto the lower roller 334 .
