Description

Technical Field

[0001] The present application relates to the field of mechanics, and in particular to a marble wire saw based on magnetic suspension tension adjustment. Background Art

[0002] At present, the multi-wire cutting machine technology uses the reciprocating motion of the diamond wire to cut hard and brittle materials. The main cutting materials are ceramics, sapphire crystals, silicon crystals, marble, magnetic materials, etc. The diamond wire is repeatedly wound by multiple sets of rollers to form multiple cutting lines, and the tension of each line must be uniform. Therefore, a tension regulator is needed to adjust the tension of the diamond wire. The tension adjustment technology currently used is mainly a swing arm tension regulator controlled by a servo motor. The main problem is uneven tension adjustment, which causes the diamond wire to break frequently during use.

[0003] In the marble cutting process, due to the large volume of marble, each diamond cutting wire needs to be more than 3 meters long, and usually 150 windings are required. Such a long diamond wire generates a lot of friction when it passes through four rollers, and then enters the pay-off wheel or take-up wheel through the tension regulator. The tension is difficult to adjust to be constant. Therefore, we proposed a marble wire saw based on magnetic levitation tension adjustment. Utility Model Content

[0030] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a marble wire saw based on magnetic suspension tension adjustment, comprising:

[0031] A frame 1, wherein four support rods are provided at four corners of the frame 1, and a rectangular frame is fixedly provided between the four support rods;

[0034] The magnetic suspension tension regulator 6 is composed of a connecting frame 10, a fixed magnet 12, a moving magnet 14 and a wiring ring 11. There are a plurality of fixed magnets 12 and moving magnets 14. The fixed magnets 12 and moving magnets 14 are arranged alternately, and the magnetic poles of the opposite surfaces of the fixed magnets 12 and moving magnets 14 are the same. The wiring ring 11 is fixedly sleeved on the outside of the moving magnet 14, and the wiring ring 11 sleeved on the outside of the moving magnet 14 is used to overlap the diamond wire. Several groups of wiring rings 11 constitute several magnetic suspension tension regulating mechanisms.

[0035] Specifically, the screw elevator 3 adopts the existing elevator on the market, which is an existing technical equipment. Four screw elevators 3 are started at the same time, which drives the rectangular frame to move up and down, and drives the active roller 4 to move up and down, so as to adjust the tightness of the diamond wire;

[0036] There are 150 moving magnets 14 , and the number of moving magnets 14 can be increased or decreased as needed.

[0037] like Figure 2 As shown: the interior of the connecting frame 10 is equidistantly and staggered with the fixed magnet 12 and the moving magnet 14, the fixed magnet 12 is fixedly arranged, the middle of the moving magnet 14 is connected with a rotating shaft 13 through a bearing, the middle of the fixed magnet 12 is provided with a rectangular groove, and the rotating shaft 13 is movably connected inside the rectangular groove.

[0038] Specifically, the fixed magnet 12 and the moving magnet 14 are both circular magnetic blocks, and the length of the rectangular groove is greater than the diameter of the rotating shaft 13 .

[0039] like Figure 1 As shown: the lower parts of the left and right ends of the frame 1 are rotatably connected to the take-up and pay-off rollers 2 through a connecting frame, and the left and right sides of the rectangular frame are rotatably connected to the active rollers 4.

[0040] Specifically, the main motor 5 adopts a motor currently available on the market, which is a prior art.

[0041] like Figure 1 As shown: the driving roller 4 and the take-up and pay-off roller 2 have the same transmission structure, and the ends of the driving roller 4 and the take-up and pay-off roller 2 are both transmission-connected to the main motor 5.

[0042] Main shafts 9 are provided at both ends of the active roller 4. The main shafts 9 are sleeved with bearing boxes 8. The bearing boxes 8 of the active roller 4 are fixedly inserted into the side walls of the rectangular frame.

[0047] Specifically: Diamond wire is used to cut marble.

[0048] Working principle: When the wire-reeling and wire-paying rollers 2 are in use, one is for reeling in the wire and the other is for paying out the wire. The two wire-reeling and wire-paying rollers 2 can be switched to each other, so that the diamond wire can be driven to move back and forth continuously. When the tightness of the diamond wire needs to be adjusted significantly, the four screw elevators 3 can be started at the same time to drive the rectangular frame to move up and down, and drive the active roller 4 to move up and down, so as to adjust the tightness of the diamond wire.

[0049] The upper ends of the wiring loops 11 of the two magnetic suspension tension regulators 6 are correspondingly connected with a diamond wire. Since a moving magnet 14 is provided between the two fixed magnets 12, the holding force between the fixed magnets 12 will push the moving magnet 14 to move outward. Since the plug-in hole of the rotating shaft 13 is rectangular, the rotating shaft 13 can be displaced inside the rectangular groove, so that the diamond wire can have a buffered displacement, thereby effectively avoiding the diamond wire from being broken due to excessive tension, and effectively protecting the diamond wire.
