Description

Technical Field

[0001] The utility model relates to the technical field of wire saw cutting machines for crystal blocks, in particular to a wire saw cutting machine for crystal blocks. Background Art

[0002] At present, when a traditional wire saw cutter cuts a crystal, first, the crystal to be cut is placed in the middle of a fixture, and then the fixture is used to clamp and fix the crystal. After clamping, the cutting fluid nozzle is directed to the position where the crystal needs to be cut. At this time, the wire saw cutter and the moving device are started. When the wire saw cutter is working, the cutting wire is driven to rotate, and the moving device drives the cutter to approach the crystal. As the cutting wire approaches, the crystal is cut.

[0003] Because traditional wire saw cutting machines use single-sided cutting when cutting crystals, if they are cutting larger crystals, when the cutting line is located in the middle of the crystal, the cutting fluid can only enter the middle of the crystal through a small cutting slit or cutting line to begin cooling the cutting line. However, the small cutting slit or cutting line will allow less cutting fluid to enter. At this time, the cutting speed is slow and the cutting direction remains unchanged. The heat generated by friction cannot be quickly cooled by the cutting fluid, which will make the cutting line longer, resulting in vibration during the cutting process, making the cutting surface rough and shortening the service life of the cutting line.

[0036] Embodiment 3

[0037] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0038] The flushing assembly 5 includes a water receiving tray 51, the bottom surface of the inner cavity of the protection box 1 is fixedly connected with the water receiving tray 51, the inner cavity of the water receiving tray 51 is provided with a water discharge hole 52, the bottom surface of the water receiving tray 51 and below the water discharge hole 52 is fixedly connected with a water receiving cylinder 53, and the inner cavity of the water discharge hole 52 is provided with a filter cylinder 54.

[0040] The working principle and use process of this utility model:

[0041] In use:

[0042] First, the crystal to be cut is placed on the rotating disk 42, and then the clamping threaded rod 44 is rotated to drive the clamping piece 45 to move toward the crystal, so that crystals of different sizes can be clamped and fixed. After clamping, the lifting motor 32 is started according to the thickness of the cut, and the lifting motor 32 drives the height threaded rod 33 to rotate. When the height threaded rod 33 rotates, it will drive the lifting column 34 to move upward, thereby driving the rotating disk 42 and the crystal to move upward, so that it is convenient to cut out the crystals in the later stage. Crystals of the same thickness, after adjustment, start to bend the hose nozzle 58, move the water outlet end of the hose nozzle 58 to the crystal cutting position, start the water pump 55, when the water pump 55 works, start to pump the cutting fluid in the water receiving nozzle 51 into the hose nozzle 58, when pumping the fluid, start filtering and intercepting the debris in the cutting fluid through the filter cartridge 54, to facilitate the centralized processing later, start the cutting motor 24, when the cutting motor 24 works, it will drive the main line wheel 23 to rotate, at this time, with the cooperation of the slave line wheel 211, The cutting line 212 is driven to rotate. When the cutting line 212 rotates, the moving motor 21-4 in the moving component 21 drives the moving threaded rod 21-3 to rotate, which can drive the cutting line 212 to move toward the crystal, thereby starting to cut crystals of different sizes. During cutting, the rotating motor 41 is started, and the rotating motor 41 drives the rotating disk 42 to rotate. When the rotating disk 42 rotates, single-sided cutting is avoided during the cutting process. When the cutting line 212 is replaced later, the tightening threaded rod 21-3 is rotated. Rod 27, tighten the threaded rod to drive the moving block 210 and the slave wire wheel 211 to move, so that the cutting line 212 can be removed and a new one can be installed. At this time, the tightening threaded rod 27 is rotated to drive the clamping block 28 to move and start squeezing the damping rod 29 by tightening the threaded rod 27, so that the damping rod 29 is compressed. When the cutting line 212 is heated and elongated later, at this time, the damping rod 29 pushes the moving block 210 to move, which can drive the slave wire wheel 211 to move, so that the cutting line 212 can be straightened later to prevent slipping.
