In another embodiment of this embodiment, as shown in fig. 2 to 4, the cutting driving mechanism 200 includes a wire releasing component 24, a wire retrieving component 25 and a cutting driving component 23, the wire releasing component 24 and the wire retrieving component 25 are respectively disposed on two opposite sides of the placing platform 11, the wire releasing component 24 and the wire retrieving component 25 are respectively connected to two ends of the cutting wire 21 for releasing and releasing the cutting wire 21, the wire cutting section 211 is located between the wire releasing component 24 and the wire retrieving component 25, a driving end of the cutting driving component 23 is connected to the wire cutting section 211 for driving and adjusting a distance between the wire cutting section 211 and the placing platform 11, and when the cutting driving component 23 drives the wire cutting section 211 to move to abut against the material on the material loading platform 51, the wire releasing component 24 and the wire retrieving component 25 perform wire releasing and retrieving actions simultaneously, so that the wire cutting section 211 rub. Specifically, when the carrier driving mechanism 52 drives the material loading platform 51 to move so that the loaded material is aligned with the wire cutting section 211, the cutting driving assembly 23 is started to drive the wire cutting section 211 to move towards the material loading platform 51, when the wire cutting section 211 is moved to be abutted against the material, the wire paying-off assembly 24 and the wire taking-up assembly 23 are started to take up and pay off the cutting wire 21, and at the moment, the wire cutting section 211 moves back and forth between the wire paying-off assembly 24 and the wire taking-up assembly 25, so that the material is cut through friction; thus, the cutting driving assembly 23 provides a feeding force for the linear cutting section 211 to cut the material, and the wire releasing assembly 24 and the wire collecting assembly 25 provide a frictional cutting force for the linear cutting section 211 to cut the material, thereby completing the linear cutting of the material.

Further, in the present embodiment, the cutting wire 21 is preferably a diamond cutting wire, i.e., a steel wire coated with diamond. Because the diamond has high strength and high hardness, the cutting line 21 made of the diamond has high rigidity and sharper cutting edges, and can be used for cutting raw stones with high hardness; and, on the basis of guaranteeing line of cut 21 cutting strength, use diamond wire to make line of cut 21 can be with the thinner of line of cut 21 to can further reduce the cutting resistance, improve cutting efficiency, can also dwindle the cutting edge of a knife simultaneously, further reduce the waste of raw materials, specially adapted cutting precious stone such as jade.

It is understood that the diameter of the diamond cutting wire 21 may be smaller when the wire cutting material of the present embodiment is used to cut a material having a smaller hardness, and thus the limitation of the diameter of the diamond cutting wire 21 is merely exemplary and not exclusive.

In another embodiment of the present invention, as shown in fig. 2 to 4, a vertical frame 14 for vertically placing the platform 11 is disposed on the mounting frame 10, and a movable frame 15 is slidably disposed on the vertical frame 14; the wire cutting device 20 further comprises a wire tensioning assembly 22, wherein the wire tensioning assembly 22 comprises a first traction member 221 and a second traction member 222 which are oppositely arranged on the movable frame 15 at intervals, the first traction member 221 and the second traction member 222 are suspended above the placing table 11 and used for drawing and tensioning the cutting wire 21, the wire cutting section 211 is formed between the first traction member 221 and the second traction member 222, and the driving end of the cutting driving assembly 23 is connected with the movable frame 15 so as to drive the movable frame 15 to perform reciprocating linear motion on the vertical frame 14 along the vertical direction (the direction perpendicular to the placing table 11), so that the wire cutting section 211 is close to or far away from the placing table 11. When the material needs to be cut, the cutting driving assembly 23 drives the movable frame 15 to drive the linear cutting section 211 to move to abut against the material on the material loading platform 51.

Specifically, because pay off axle 241 is for having the tubular structure of certain length, the even coiling of the length of pay off axle 241 of cutting line 21 along pay off axle 241 is on pay off axle 241, and it can't ensure that cutting line 21 releases from same position all the time to pay off axle 241 when releasing cutting line 21 under the general condition, and cutting line 21 just can swing because the position of releasing is different like this to the drive line cutting section 211 that can certain degree takes place the swing, influences the precision of cutting. On this basis, the first linear module 243 is arranged to drive the pay-off shaft 241 to rotate by the first rotating motor 244, and simultaneously, the first linear module 243 drives the pay-off shaft 241 to uniformly reciprocate along the direction perpendicular to the cutting line 21, so that the cutting line 21 wound on the pay-off shaft 241 can be released from the same position, and thus, the cutting line 21 just released and the linear cutting segment 211 can be always kept in the same plane, as shown in fig. 5, the cutting line 21 and the linear cutting segment 211 are prevented from swinging during cutting, and a guarantee is provided for accurate cutting.
