In order to improve the cutting efficiency of the cutting wire, a corrugated structure is usually set on the cutting wire. The formation of the corrugated structure on the cutting wire is mainly formed by gear extrusion.
[0003] However, the cutting wire is usually made of wire with high tensile strength and high hardness. When the corrugated structure is formed by gear extrusion, the cutting wire will recover its shape, making it difficult for the formed corrugated structure to reach the expected size.

DETAILED DESCRIPTION
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but is not limited thereto. Any improvement or substitution on the basic spirit of the embodiments of the present invention still falls within the scope of protection of the present invention.
[0023] like Figure 1 and 3 As shown, a cutting wire manufacturing device includes a unwinding mechanism 1, a winding mechanism 6, a heating mechanism, a deformation mechanism and a stress relief mechanism, wherein the unwinding mechanism 1 is used to unwind the wire, the heating mechanism is located between the unwinding mechanism 1 and the winding mechanism 6, the deformation mechanism is located between the heating mechanism and the winding mechanism 6, the stress relief mechanism is located between the winding mechanism 6 and the deformation mechanism, and the deformation mechanism includes at least one group of gear sets 3 with helical teeth.
[0024] like Figure 1 As shown, specifically, in some embodiments, the heating mechanism includes a first guide sleeve 21 and a first electric heating device arranged on the first guide sleeve 21, the first electric heating device is a resistance wire 7, and the resistance wire 7 is wound on the first guide sleeve 21. The stress relief mechanism includes a second guide sleeve 51 and a second electric heating device arranged on the second guide sleeve 51, the second electric heating device is a resistance wire 7, and the resistance wire 7 is wound on the second guide sleeve 51. The gear set 3 with helical teeth includes two gears with helical teeth that are meshed with each other, wherein the number of teeth of the gears with helical teeth is 20 to 60, which can be selected according to actual needs, and the tooth top of the gear can be set to a circular arc transition, and the cross-section of the gear teeth can also be set to a trapezoidal shape, such as Figure 3 and 4 As shown, preferably, the gear set with helical teeth is a helical cylindrical gear set or a helical bevel gear set.
[0025] The method for manufacturing a cutting wire using the above-mentioned equipment is as follows: after the wire is unwound by the unwinding mechanism 1, it passes through the first guide sleeve 21 of the heating mechanism. The heating mechanism heats the wire to increase the plasticity of the wire, which can reduce the recovery amount of the wire after deformation, and is more conducive to making the deformation reach the expected size. After the resistance wire 7 is energized to generate heat, the heat is transferred to the first guide sleeve 21, and the first guide sleeve 21 heats the wire. In some embodiments, in order to increase the heat transfer speed of the guide sleeve, the guide sleeve can be set to a metal, such as a copper guide sleeve. When steel wire is used as the wire, the heating temperature can be set to 580°C to 600°C. Then the wire passes between two mutually meshing gears with helical teeth as a deformation mechanism. Under the extrusion of the helical teeth, the wire is deformed to form a corrugated structure. Since the contact and meshing position of the helical teeth is gradually changed, compared with the deformation of the wire by the spur gear, the corrugated structure will be further stretched to one side to a certain extent to form a three-dimensional corrugated structure. After the wire is deformed, the wire is heated again by the second electric heating device of the stress relief mechanism. The heating principle is the same as the heating mechanism, which can eliminate the residual stress of the wire and improve the performance of the wire. The specific temperature can be set between 450 and 500° C. Finally, the wire is coiled by the coiling mechanism 6. The wire can be a steel wire or a tungsten wire.
[0026] like Figure 2 As shown, as another implementation of the heating mechanism, in some embodiments, the heating mechanism includes an electromagnetic induction coil 9. Compared with the resistance wire 7, the electromagnetic induction coil 9 has the advantages of fast heating speed and more accurate temperature control.
[0027] like Figure 1 and 2 As shown, in order to further improve the deformation effect, in some embodiments, the number of the gear sets 3 with helical teeth is two, each of which includes two gears with helical teeth meshing with each other, and the two gear sets 3 with helical teeth have the same structure. The wire is deformed by using two gear sets 3 with helical teeth, that is, deformed twice, so that the deformation of the wire can reach the expected size.
[0028] like Figure 1 and 2 As shown, in some embodiments, the deformation mechanism is arranged on the rotating seat 4, and the rotating seat 4 is connected to the power mechanism 43 to realize rotation. The rotating seat 4 can drive the deformation mechanism to rotate, thereby causing the wire to produce a spiral deformation, so that the wire has deformation in all directions of the circumference, which is conducive to improving the cutting efficiency of the cutting wire.
[0029] In order to facilitate the routing of the rotating seat 4, specifically, in some embodiments, a threading hole 41 and a wire outlet hole 42 are respectively provided at both ends of the rotating seat 4, the threading hole 41 is located between the deformation mechanism and the unwinding mechanism 1, and the wire outlet hole 42 is located between the deformation mechanism and the unwinding mechanism 1. After being heated by the heating mechanism, the wire passes through the threading hole 41, the gear set 3 with helical teeth of the deformation mechanism, and the wire outlet hole 42 in sequence.
[0030] like Figure 2 As shown, in some embodiments, the stress relief mechanism includes an electromagnetic induction coil 9. The specific implementation of the stress relief mechanism and the specific implementation of the heating mechanism can be combined with each other, such as the stress relief mechanism using the electromagnetic induction coil 9 and the heating mechanism using the heating method of the resistance wire 7, or vice versa.
[0031] In order to prevent the wire from contacting the heating mechanism and the stress relief mechanism, which may cause wear and damage to the wire, the heating mechanism or the stress relief mechanism, in some embodiments, both sides of the heating mechanism and the stress relief mechanism are provided with guide wheels 8. The design of the guide wheels 8 is conducive to improving the practical life of the device.
[0032] It should be noted that the embodiments described above are only used to explain the present invention and do not constitute any limitation to the present invention. The present invention has been described with reference to typical embodiments, but it should be understood that the words used therein are descriptive and explanatory words, rather than restrictive words.
