The second clamping rod 3262 is fixedly connected to the end of the first clamping rod 3261 facing away from the wire rope 31, with the length of the second clamping rod 3262 perpendicular to the length of the first clamping rod 3261. The second clamping rod 3262 is inserted into the insertion slot 3221 and rotated to engage with the clamping slot 3222. A plurality of first fixing grooves 3223 are provided on the side wall of the first rotating shaft 322 , and the plurality of first fixing grooves 3223 are arranged axially along the first rotating shaft 322 . The first fixing grooves 3223 are provided circumferentially along the first rotating shaft 322 , and both ends of the wire rope 31 are respectively wound in the first fixing grooves 3223 on the two first rotating shafts 322 .
[0051] The wire rope 31 is wound around the round rod 7, the second clamping rod 3262 is inserted into the insertion slot 3221, and the second clamping rod 3262 is rotated so that the second clamping rod 3262 is clamped into the clamping slot 3222, thereby fixing the ends of the wire rope 31 to the two first rotating shafts 322. The two turbines 323 drive the two first rotating shafts 322 to rotate away from each other, thereby tensioning the wire rope 31.
[0052] Reference Figure 3 and Figure 5 The second tensioning assembly 33 includes a fixed plate 331, which is fixedly connected to the ends of two adjacent connecting plates 24 away from the fixed block 23. The fixed plate 331 is a horizontally arranged U-shaped plate, with both fixed plates 331 open on the sides facing away from each other. A second rotating shaft 332 is rotatably connected to each of the fixed plates 331. The second rotating shaft 332 is axially parallel to the length of the support box 111. The second rotating shaft 332 defines a plurality of second fixing slots 3321, which are arranged axially along the second rotating shaft 332 and circumferentially extend along the second rotating shaft 332. The second fixing slots 3321 are used to wind the wire rope 31. A ratchet 333 is coaxially fixedly connected to the second rotating shaft 332 near the first rotating handle 325.

The other end of the fastening bolt 336 is fixedly connected to a second rotation handle 337, which is used to drive the rocker 334 to slide circumferentially along the adjustment slot 3311. A bidirectional pawl 338 is hingedly connected to the top of the rocker 334, facing the fixed plate 331. The bidirectional pawl 338 comprises two fixedly connected pawls, symmetrically arranged with their connecting surfaces facing each other. The bidirectional pawl 338 is used to rotate the ratchet 333 in both directions.
[0053] The second rotating handle 337 is rotated to loosen the fastening bolt 336. The second rotating handle 337 is then swung back and forth along the circumference of the adjustment slot 3311. This causes the rocker 334 to swing back and forth, which in turn causes the two-way pawl 338 to swing back and forth. One of the two-way pawls 338 abuts one side of the teeth of the ratchet wheel 333, thereby rotating the ratchet wheel 333. To change the direction of the ratchet wheel 333, the two-way pawl 338 is rotated away from the ratchet wheel 333, causing the other pawl in the two-way pawl 338 to abut the other side of the teeth of the ratchet wheel 333. The second rotating handle 337 is then rotated in the opposite direction, thereby rotating the ratchet wheel 333 in the opposite direction. The forward and reverse rotation of the ratchet wheel 333 drives the second rotating shaft 332 in the forward and reverse directions, thereby fine-tuning the tension and release of the wire rope 31.

The other end of the coil spring 56 is fixedly connected to a pulling rope 57, which extends from the bottom opening of the installation box 54. The bottom end of the pulling rope 57 is fixedly connected to a rope loop 58, which is used to wrap around the top of the steel wire rope 31 of the second clamping mechanism 4 and pull it upward.
[0056] After completing a cut, the steel wire rope 31 of the second clamping mechanism 4 is loosened, and the coil spring 56 contracts to drive the pulling rope 57 to slide upward, and the pulling rope 57 drives the top of the steel wire rope 31 of the second clamping mechanism 4 to slide upward, so that the round material rod 7 slides along the conveying direction in the steel wire rope 31 of the second clamping mechanism 4. After sliding a certain distance, the steel wire rope 31 is tightened again. At this time, the steel wire rope 31 drives the pulling rope 57 to slide toward the direction close to the round material rod 7, and the round material rod 7 is fixed again, so as to facilitate cutting again.
[0057] The implementation principle of a double-clamping mechanism horizontal band sawing machine according to the embodiment of the present application is as follows: the steel wire rope 31 of the first clamping mechanism 3 and the second clamping mechanism 4 is wound around the round material rod 7, the second clamping rod 3262 is inserted into the insertion groove 3221, and the second clamping rod 3262 is rotated so that the second clamping rod 3262 is clamped into the clamping groove 3222, thereby fixing both ends of the steel wire rope 31 to the first rotating shaft 322. The first rotating handle 325 of the first clamping mechanism 3 is rotated, and the first rotating handle 325 drives the worm 324 to rotate, and the worm 324 drives the two turbines 323 to rotate away from each other, and the two turbines 323 drive the two first rotating shafts 322 to rotate away from each other, thereby tensioning the steel wire rope 31 and completing the fixation of one end of the round material rod 7.
[0058] Rotating the first rotating handle 325 of the second clamping mechanism 4 also tightens the steel wire rope 31, but leaves a certain amount of adjustment space. Rotating the second rotating handle 337 of the second clamping mechanism 4 loosens the fastening bolt 336, and the second rotating handle 337 swings back and forth along the adjustment slot 3311. The second rotating handle 337 drives the rocker 334 to swing back and forth, which in turn drives the two-way pawl 338 to swing back and forth. One of the two-way pawls 338 abuts against one side of the teeth of the ratchet wheel 333, thereby rotating the ratchet wheel 333 away from the round material rod 7. The ratchet wheel 333 drives the second rotating shaft 332 to rotate away from the round material rod 7, thereby tightening the steel wire rope 31 and fixing the cut end of the round material rod 7 to facilitate cutting.
[0059] After completing a cut, the bidirectional pawl 338 is rotated away from the ratchet 333, causing the other pawl in the bidirectional pawl 338 to abut against the other side of the ratchet 333 teeth. The second rotating handle 337 is then rotated in the opposite direction, thereby shifting the ratchet 333 in the opposite direction. The ratchet 333 then causes the second rotating shaft 332 to rotate in the opposite direction, thereby loosening the wire rope 31. The coil spring 56 contracts, causing the pull rope 57 to slide upward, which in turn causes the top of the wire rope 31 of the second clamping mechanism 4 to slide upward, causing the round material rod 7 to slide within the wire rope 31 in the conveying direction. After sliding a certain distance, the wire rope 31 is re-tensioned, and the cut end of the round material rod 7 is secured again, facilitating further cutting.
[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
