[0002] Diamond wire has many advantages such as high-speed cutting, smaller kerf, environmentally friendly production, low cost, and high cost performance, and will gradually replace the traditional mortar wire cutting method. At present, there are two types of diamond wire saws in the field of electroplated wire, one is a straight diamond wire saw, and the other is a ring-twisted diamond wire saw. The straight diamond wire saw needs to reciprocate during cutting, and the reversal of the wire saw will leave ripples on the cutting surface, reduce the surface accuracy, and have low cutting efficiency. Therefore, the application of the straight diamond wire saw has certain limitations.

DETAILED DESCRIPTION

[0050] The present invention is further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0054] Specifically, the first transmission shaft 2, the frame 3 and the wire splitting structure 5 are sequentially arranged at the top of the bracket 1, and the wire pay-off assembly 4 is arranged inside the frame 3. The twisted wire is paid out by the wire pay-off assembly 4 and passes through the threading hole reserved on the frame 3 to enter the wire splitting structure 5. During the wire pay-off process, the first driving structure drives the first transmission shaft 2 to rotate, and the first transmission shaft 2 rotates to drive the frame 3 to rotate. When the frame 3 rotates, it drives the wire pay-off assembly 4 and the twisted wire to rotate. Since the wire pay-off direction of the twisted wire is the same as the axial direction of the first transmission shaft 2, when the wire is paid off, the first transmission shaft 2 rotates to make the twisted wire rotate, so as to rotate the twisted wire from a twisted state to a non-twisted state, that is, the side wire originally wound on the core wire is unwound, and the side wire and the core wire become parallelly distributed. After the staff separates the parallel distributed side wire from the core wire, they fix the side wire and the core wire on the wire splitting structure 5 respectively, so as to realize the separation of the side wire and the core wire.

The support plate 37 is provided with a mounting position for fixing the pay-off assembly 4. A plurality of counterweights 38 are arranged at intervals on the third crossbar 35 and the fourth crossbar 36 to balance the weight of the support plate 37 and the pay-off assembly 4, so that the frame 3 is more stable when rotating. When paying out the wire, the stranded wire is paid out by the pay-off assembly 4 located inside the frame 3, passes through the through hole in the center of the second disc 32, and then enters the branching structure 5.

[0059] See also Figure 3 The pay-off assembly 4 includes: a second driving structure 41, a second transmission shaft 42, a pay-off wheel 43, a direction-changing wheel 44, a third driving structure 45, a wire wheel group 46 and a positioning wheel 47. Among them, the second driving structure 41 is fixedly connected to the first disc 31. The second transmission shaft 42 is arranged parallel to the first transmission shaft 2, and one end of the second transmission shaft 42 is connected to the second driving structure 41, and can rotate under the drive of the second driving structure 41. The pay-off wheel 43 is located between the first disc 31 and the second disc 32, and the pay-off wheel 43 is connected to the other end of the second transmission shaft 42, and can rotate under the drive of the second transmission shaft 42.

The positioning wheel 47 is disposed on the support plate 37 and is located on a side of the guide wheel assembly 46 away from the first crossbar 33 .

[0060] Specifically, the second driving structure 41 is fixedly arranged on the side of the first disc 31 facing the first transmission shaft 2. The second transmission shaft 42 passes through the first disc 31, one end of the second transmission shaft 42 is connected to the output end of the second driving structure 41, and the other end of the second transmission shaft 42 is connected to the end face of the pay-off wheel 43. The second transmission shaft 42 can drive the pay-off wheel 43 to rotate under the drive of the second driving structure 41. The change-direction wheel 44, the third driving structure 45, the wire wheel group 46 and the positioning wheel 47 are all fixed on the support plate 37. The change-direction wheel 44 is fixed on the support plate 37 at a position close to the first disc 31, and the change-direction wheel 44 is aligned with the pay-off wheel 43 in a direction perpendicular to the second transmission shaft 42, and the circumference of the change-direction wheel 44 is perpendicular to the circumference of the pay-off wheel 43. The wire wheel group 46 is located on the side of the change-direction wheel 44 close to the second disc 32, and the third driving structure 45 is located on the side of the wire wheel group 46 away from the first crossbar 33, and the wire wheel group 46 rotates under the drive of the third driving structure 45. The positioning wheel 47 is located on the side of the wire wheel group 46 away from the first crossbar 33, and a twisted wire channel aligned with the central through hole of the second disc 32 is formed between the positioning wheel 47 and the wire wheel group 46. When the wire is released, the twisted wire is wound on the wire release wheel 43 along the circumference of the wire release wheel 43. When the wire release wheel 43 rotates, the twisted wire is released by the wire release assembly 4 located inside the frame 3, and passes through the direction-changing wheel 44 in a direction perpendicular to the axial direction of the second transmission shaft 42. The direction-changing wheel 44 changes the wire release direction of the twisted wire to a direction parallel to the axial direction of the second transmission shaft 42, so that the twisted wire passes through the twisted wire channel between the positioning wheel 47 and the wire wheel group 46 and the central through hole of the second disc 32 in sequence along the axial direction of the first transmission shaft 2.

[0061] In one practicable manner, the third driving structure 45 includes a motor, and the output end of the third driving structure 45 is driven by a belt and a wire pulley set 46 .

[0062] Furthermore, the second driving structure 41 includes a damper. The surface of the direction-changing wheel 44 has a V-shaped groove.

[0063] Specifically, the second driving structure 41 is an MTB-04 damper. The second driving structure 41 is fixed to the side of the first disc 31 facing the first transmission shaft 2 through a damper bracket. The second transmission shaft 42 is fixed to the first disc 31 through a bearing seat. The output end of the second driving structure 41 is connected to the second transmission shaft 42 through a coupling to drive the second transmission shaft 42 to rotate.

[0064] In this embodiment, the wire wheel assembly 46 includes: a multi-grooved roller 461 and a grooveless roller 462. The multi-grooved roller 461 is arranged on the side of the direction-changing wheel 44 close to the second disc 32, and the grooveless roller 462 is arranged on the side of the multi-grooved roller 461 close to the second disc 32. The positioning wheel 47 is arranged on the side of the grooveless roller 462 away from the first crossbar 33, and a twisted wire channel is formed between the positioning wheel 47 and the grooveless roller 462. The third driving structure 45, the multi-grooved roller 461 and the grooveless roller 462 are driven by a belt.

[0065] Specifically, the output end of the third driving structure 45 passes through the support plate 37. The multi-grooved roller 461 and the grooveless roller 462 are fixed on the support plate 37 through shafts and bearings, and the shafts of the multi-grooved roller 461 and the grooveless roller 462 pass through the support plate 37, that is, the third driving structure 45, the multi-grooved roller 461 and the grooveless roller 462 are all located on one side of the support plate 37, and the output shaft of the third driving structure 45, the shaft of the multi-grooved roller 461 and the shaft of the grooveless roller 462 are all located on the other side of the support plate 37. The output shaft of the third driving structure 45, the shaft of the multi-grooved roller 461 and the shaft of the grooveless roller 462 are driven by a belt, so that the multi-grooved roller 461 and the grooveless roller 462 can rotate under the drive of the third driving structure 45. The positioning wheel 47 is located on the side of the grooveless roller 462 away from the first crossbar 33, and a twisted wire channel aligned with the central through hole of the second disc 32 is formed between the positioning wheel 47 and the grooveless roller 462. When the twisted wire passes through the direction-changing wheel 44, it passes through the multi-grooved roller 461, the twisted wire channel between the positioning wheel 47 and the grooveless roller 462, and the central through hole of the second disc 32 in sequence. It should be noted that although the side wires and the core wires of the twisted wire have changed from a twisted state to a parallel distribution after the self-rotation, there is still a packaged wire net on the periphery of the twisted wire. In order to prevent the packaged wire net from affecting the splitting of the twisted wire during the process of paying out the wire, the present embodiment cuts the packaged wire net by the multi-grooved roller 461 and the grooveless roller 462 to prevent the packaged wire net from affecting the splitting of the twisted wire.

[0066] In one practicable manner, the pay-off assembly 4 further comprises a belt pressure wheel, which is fixedly connected to the second cross bar 34 via a bearing and a shaft, and a curved surface of the belt pressure wheel contacts the outer surface of the belt to control the tension of the belt.

[0067] In one feasible manner, the third drive structure 45, the multi-grooved roller 461 and the grooveless roller 462 are distributed in an isosceles triangle, and the distance between the third drive structure 45 and the multi-grooved roller 461 is equal to the distance between the third drive structure 45 and the grooveless roller 462, so that the transmission between the third drive structure 45, the multi-grooved roller 461 and the grooveless roller 462 is more stable.

[0068] See also Figure 5The surface of the wire dividing structure 5 is provided with a first wire dividing hole 51 and a plurality of second wire dividing holes 52. The center of the first wire dividing hole 51 is aligned with the center of the first transmission shaft 2, and the plurality of second wire dividing holes 52 are distributed on the same circumference with the first wire dividing hole 51 as the center.

[0069] Specifically, the branching structure 5 is arranged on a side of the frame 3 away from the first transmission shaft 2, and the axis of the branching structure 5 is aligned with the axis of the first transmission shaft 2, the first branching hole 51 is located at the center of the branching structure 5, and a plurality of second branching holes 52 are distributed on the periphery of the first branching hole 51, and are all distributed on the same circumference with the first branching hole 51 as the center, and the relative position relationship between the plurality of second branching holes 52 and the first branching hole 51 corresponds to the relationship between a plurality of side wires and core wires in the twisted wire, and the number of the second branching holes 52 corresponds to the number of side wires in the twisted wire. In this embodiment, the number of the second branching holes 52 and the number of side wires in the twisted wire are both 6. When the wire is released, the twisted wire rotates with the rotation of the frame 3. After the rotation, the twisted wire changes from a twisted state to a non-twisted state, that is, the side wire originally wrapped around the core wire is unwound, and the side wire and the core wire become parallelly distributed. After the non-twisted twisted wire passes through the multi-grooved roller 461 and the grooveless roller 462, the encapsulated wire net around the twisted wire is cut open, and under the action of the positioning wheel 47 and the grooveless roller 462, the twisted wire passes through the twisted wire channel between the positioning wheel 47 and the grooveless roller 462 and enters the central through hole of the second disc 32. The staff passes the core wire through the first branching hole 51 in the center of the branching structure 5, and passes the side wire through the second branching hole 52. One side wire passes through one second branching hole 52, and the side wire and the core wire are collected on the side of the branching structure 5 away from the frame 3 to obtain the split side wire and core wire. Preferably, pulling force is applied to the side wire and the core wire respectively on the side of the wire branching structure 5 away from the frame 3, so that the twisted wire has a certain tension during the wire unwinding process, and the twisted wire is kept in a taut state.

[0070] In this embodiment, the twisted wire pay-off mechanism further includes a through-hole slip ring 6. The through-hole slip ring 6 is sleeved on the first transmission shaft 2 to ensure that the electrical connection line of the twisted wire pay-off mechanism will not be entangled.

[0071] The present embodiment provides a twisted wire pay-off mechanism, which drives the first transmission shaft 2 to rotate through the first driving structure to drive the frame 3 to rotate, and the frame 3 rotates to drive the pay-off assembly 4 to rotate, and the twisted wire is paid out by the pay-off assembly 4. Therefore, the rotation of the first transmission shaft 2 can make the twisted wire rotate, thereby rotating the twisted wire from a twisted state to a non-twisted state, that is, the side wire originally wound on the core wire is unwound, and the side wire and the core wire become parallelly distributed, so that the side wire and the core wire are separated. The twisted wire pay-off mechanism provided in this embodiment can reduce the labor cost in the production process of the annular twisted diamond wire saw, and the pay-off speed can reach 36 meters / hour, which effectively improves the production efficiency of the twisted diamond wire saw.
