For example, a first head clamp may be referred to as a second head clamp, and similarly, a second head clamp may be referred to as a first head clamp; a first support surface may be referred to as a second support surface, and similarly, a second support surface may also be referred to as a first support surface; without departing from the scope of the various described embodiments. Furthermore, as used herein, the singular forms "a", "an", and "the" are intended to include plural forms as well, unless otherwise indicated in the context.

[0042] like Figure 1As shown, the utility model provides a circular wire cutting device, which is applied to a cutting and grinding machine. The circular wire cutting device includes a track group 10 and a cutting table 20, a clamping and positioning mechanism 30, and a circular wire cutting mechanism 40. The track group 10 is arranged on a frame 01 of the cutting and grinding machine, the cutting table 20 is arranged on the frame 01, the clamping and positioning mechanism 30 is arranged on the cutting table 20, and the circular wire cutting mechanism 40 is reciprocatingly arranged on the track group 10.

[0043] like Figure 1 and Figure 2 , Figure 4 As shown, the track group 10 includes a first track 11 and a second track 12 arranged in parallel, and the cutting table 20 is arranged between the first track 11 and the second track 12, and is used to carry two square silicon rods 02 placed horizontally in parallel, and the length direction of the square silicon rods 02 is along the length direction of the first track 11. Further, the first support surface 22 and the second support surface 23 are used to carry the two square silicon rods 02 placed horizontally in parallel, and the free end of the cantilever table 21 is defined as the head. In addition, the cantilever table 21 and its first support surface 22 and the second support surface 23 can also be replaced by various suitable existing technologies.

[0044] like Figures 1 to 3 As shown, the clamping and positioning mechanism 30 is used to clamp and position the two square silicon rods 02 on the cutting table 20. Specifically, the clamping and positioning mechanism 30 includes a first head clamp 31 and a first tail clamp 33 provided at both ends of the first support surface 22, a second head clamp 32 and a second tail clamp 34 provided at both ends of the second support surface 23, and a tail clamp driving member 35 for driving the first tail clamp 33 and the second tail clamp 34. The first head clamp 31 and the first tail clamp 33, the second head clamp 32, and the second tail clamp 34 all include two left and right clamping elements, so that the square silicon rod 02 can still be clamped after being cut into two left and right square silicon rods after cutting, which is easy to understand for those skilled in the art. In addition, various parts / components / parts constituting the clamping and positioning mechanism 30 can also adopt various suitable existing technologies. Alternatively, the clamping and positioning mechanism 30 only has a clamping function, in which case it is a clamping mechanism, while the positioning function is completed by other structures, or various existing technologies may be adopted.

[0045] like Figures 1 to 5As shown, the ring wire cutting mechanism 40 includes a ring cutting wire 41 and a cutting frame 42, and a plurality of cutting wheels (431, 432, 441, 442) arranged on the cutting frame 42, the first cutting wheel group 43 is composed of a first upper cutting wheel 431 and a first lower cutting wheel 432, and the second cutting wheel group 44 is composed of a second upper cutting wheel 441 and a second lower cutting wheel 442. One side of the ring cutting wire 41 is wound around the first upper cutting wheel 431 and the first lower cutting wheel 432, and the other side is wound around the second upper cutting wheel 441 and the second lower cutting wheel 442. The portion wound around the first upper cutting wheel 431 and the first lower cutting wheel 432 forms a first cutting section 45, and the portion wound around the second upper cutting wheel 441 and the second lower cutting wheel 442 forms a second cutting section 46. The first cutting section 45 and the second cutting section 46 are both arranged vertically, and the first cutting section 45 and the second cutting section 46 are respectively used to perform cutting operations on two parallel horizontally placed square silicon rods 02 carried on the cutting table 20. The first cutting segment 45 and the second cutting segment 46 form a double cutting saw, that is, one annular cutting line 41 forms a double cutting saw.

[0046] like Figure 1 and Figure 2 , Figure 4 As shown, the cutting frame 42 is a door-type or frame-type and is reciprocatingly disposed on the track set 10. Figure 6 and Figure 7 shown. Figure 8 The figure shows that the cutting frame 42 is installed on the track set 10 and has four mating parts (not marked but also obvious) that respectively cooperate with the track 11 and the track 22. The four mating parts can reciprocate on the track 11 and / or the track 12, so that the cutting frame 42 can reciprocate on the track set 10.

[0047] In an alternative embodiment, Figure 6 and Figure 7 As shown, both ends of the cutting table 20 have support structures (i.e., the structure of the cantilever table 21 is not adopted), and the support structures at both ends are arranged on the frame 01. The circular wire cutting mechanism 40 is located between the two ends of the cutting table 20. The cutting table 20 has two cutting seams matching the first cutting section 45 and the second cutting section 46 (double cutting saw). Of course, as Figures 1 to 3 As shown, when the cutting table 20 is a cantilever table 21, the cantilever table 21 also needs to have two cutting slits. The cutting table 20 that carries two parallel square silicon rods 02 must have "two cutting slits". This part can be understood as common sense. The cutting slits must be provided so that the cutting of the ring wire cutting mechanism 40 can proceed normally. Figure 6 and Figure 7 In the figure, the right side is defined as the head of the cutting table 20, such as Figure 6 and Figure 7In the figure, it is defined that the circular wire cutting mechanism 40 is located on one side of the head of the cutting table 20.

[0048] Obviously, in Figure 6 and Figure 7 In the Figures 1 to 3 The clamping and positioning mechanism 30 has different structures. Of course, Figures 1 to 3 3 is a corresponding scheme diagram, wherein the various components of the corresponding clamping and positioning mechanism 30, such as the first head clamping member 31, the first tail clamping member 33, the second head clamping member 32, the second tail clamping member 34, and the tail clamping driving member 35, are all existing technologies; and Figure 6 and Figure 7 In the figure, it is a display of production, which has some improvements compared with the prior art, but its functions are the same or similar, and its driving member 35 is Figure 2 and Figure 3 The tail clamping drive member 35 in the embodiment is quite different, but this does not change the essence that the clamping and positioning mechanism 30 in the present invention can adopt various existing or alternative solutions.

[0049] Figure 6 and Figure 7 The driving mechanism of the cutting frame 42 is shown in the figure (but not labeled), including a driving motor and a gear connected to the output of the driving motor, and a rack parallel to the track 11 (and / or the track 12), and the gear rack cooperates to drive the cutting frame 42 to reciprocate on the track set 10.

In addition, more transition wheels can be used or the distance between the existing transition wheel and the cutting wheel can be increased, so as to extend the length of the loop cutting wire 41 in disguise, improve its service life, or facilitate adjustment of the spacing between the first cutting segment 45 and the second cutting segment 46.
