[0021] The operation method of the aerated block cutting machine is as follows:

[0022] S1: The concrete aerated block blank is positioned on the base through the existing fixture. When cutting, the user starts the servo motor and the electric cylinder. The output screw of the servo motor will drive the gantry to move toward the aerated block blank according to the processing speed. The electric cylinder will drive the two loading frames to move back and forth synchronously through the cross frame. The loading frame drives the inner slider to move synchronously through the guide rail and the support table. The inner slider drives the fixedly connected storage cylinder to move. The moving block is locked in the storage cylinder. At the same time, both ends of the cutting wire are fixedly connected to the corresponding moving blocks. The cutting wire is in a tensioned state. At this time, the cutting wire will move back and forth synchronously and quickly to facilitate cutting of the aerated block blank;

[0023] S2: When the support table drives the inner slider to move back and forth along the guide column, the wavy second slide groove on the guide column will exert pressure on the vertical rod, so that the vertical rod can drive the inner slider to move back and forth through the tension plate. At this time, the inner slider will drive the cutting wire to move synchronously through the storage tube. The cutting wire moves back and forth with a small movement amount directly facing the incision of the aerated block to prevent the cutting wire from being continuously squeezed on the aerated block blank with excessive pressure, thereby reducing the risk of breaking and damage of the cutting wire;

[0024] S3: At the same time, the support platform will also drive the limit platform to move synchronously during its movement. Since the force-bearing rod on the side wall of the limit platform is fitted and embedded in the inclined first sliding groove provided on the side wall of the guide column, the force-bearing rod will drive the limit platform to move up and down reciprocatingly. The limit platform drives the rotating rod to rotate reciprocatingly through the rotatably connected guide rod. At this time, the arc-shaped toothed plate fixedly connected to the end of the rotating rod will rotate synchronously, and the arc-shaped toothed plate will rotate the transmission gear ring synchronously. At this time, the transmission gear ring will drive the transmission rod to rotate synchronously through the rotating sleeve and the fastening rod, and the transmission rod will drive the cutting wire to rotate synchronously through the sleeve and the moving block, so that the cutting wire itself can rotate, thereby improving the cutting effect and preventing one side of the cutting wire from being continuously cut, so as to reduce the risk of the cutting wire breaking.

[0025] S4: When the cutting wire cuts the aerated block blank, the cutting wire will be subjected to the reverse pressure of the aerated block blank, so that the support platform drives the guide column to move relatively as a whole. At this time, the guide column will drive the docking frame to move synchronously, so that the docking frame will further compress the pressure spring. When the reverse pressure on the cutting wire is too large, in order to prevent the cutting wire from breaking, the support platform will drive the control frame on the storage tube to move to the trigger position. At this time, the control frame will be able to squeeze on the opening outer wall of the door frame, and the control frame will drive the thrust teeth to move synchronously, so that the thrust teeth can push the corresponding force-bearing block to move, and the force-bearing block will drive the corresponding positioning plate to move to compress the reset spring. At the same time, the teeth of the positioning plate will move away from the moving block to release the locking relationship, so that the cutting wire can pull the moving block to move in the storage tube, thereby reducing the risk of the cutting wire being damaged due to the instantaneous excessive resistance of the aerated block blank. In the process of the moving block moving to pull the tension spring, the teeth of the positioning plate are attached to the side wall of the moving block.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: during the use of the concrete aerated block cutting machine and the method of use, the cutting wire can move horizontally and vertically in the horizontal plane, the cutting wire is pulled horizontally to cut the aerated block, and the vertical movement with a small displacement is used to prevent the cutting wire from being continuously compressed to increase the service life and reduce the risk of breakage. At the same time, the cutting wire itself can also rotate to prevent one side of the cutting wire from being continuously compressed and improve the cutting effect. The specific contents are as follows:

[0027] 1. A second chute vertically penetrating is formed in the guiding column. The second chute has a wavy structure. A vertical rod slidably penetrates through the middle of the second chute. Corresponding tension plates are fixedly connected to both ends of the vertical rod. One end of each tension plate is attached to the guiding column, and the other end of each tension plate is fixedly connected to the outer wall of the inner slider. The tension plates are slidably inserted into the inner wall of the support platform. The loading rack can drive the corresponding support platform to move horizontally. At this time, the inner slider on the support platform will drive the storage cylinder to move synchronously, so that the moving block in the storage cylinder will drive the cutting wire to move horizontally synchronously. During this process, the inner slider moves synchronously along the guiding column, and the vertical rod will drive the tension plate to reciprocate under the action of the second chute. The tension plate will drive the inner slider to move vertically a small distance synchronously. As can be seen from the above steps, the cutting wire will move synchronously;

[0028] 2. An inclined first chute is formed on the side wall of the guiding column. The first chute is inclined. The end of a force-bearing rod is fittingly inserted into the middle of the first chute. The force-bearing rod is fixed on the vertically slidably mounted limiting platform, so that the force-bearing rod can drive the limiting platform to move vertically. During this process, the limiting platform can drive the arc-shaped toothed plate to rotate synchronously through the guiding rod and the rotating rod. At this time, the arc-shaped toothed plate will drive the transmission toothed ring to rotate, and the transmission toothed ring will drive the fastening rod to rotate through the rotating sleeve. The fastening rod drives the moving block to rotate through the transmission rod and the sleeve, so that the moving block can drive the cutting wire itself to rotate to improve the cutting effect.

[0051] The operation method of the aerated block cutting machine is as follows:

[0052] S1: The concrete aerated block blank is positioned on the base 1 through an existing fixture. During cutting, the user starts the servo motor 2 and the electric cylinder 4. The output screw of the servo motor 2 will drive the gantry 3 to move towards the aerated block blank at the processing speed. The electric cylinder 4 will drive the two loading racks 6 to move synchronously and reciprocally through the cross frame 5. The loading rack 6 will drive the inner slider 9 to move synchronously through the guide rail 8 and the support table 7. The inner slider 9 will drive the fixedly connected storage cylinder 10 to move. The moving block 11 is locked in the storage cylinder 10. At the same time, both ends of the cutting wire 13 are fixedly connected to the corresponding moving blocks 11, and the cutting wire 13 is in a tensioned state. At this time, the cutting wire 13 will move synchronously and reciprocally quickly to facilitate the cutting of the aerated block blank;

[0053] S2: During the process that the support table 7 drives the inner slider 9 to reciprocate along the guide post 22, the wavy second chute 24 on the guide post 22 will exert pressure on the vertical rod 25, so that the vertical rod 25 can drive the inner slider 9 to reciprocate through the tension plate 26. At this time, the inner slider 9 will drive the cutting wire 13 to move synchronously through the storage cylinder 10. The cutting wire 13 reciprocates with a small movement amount facing the aerated block cut to prevent the cutting wire 13 from continuously squeezing on the aerated block blank with excessive pressure, thereby reducing the risk of the cutting wire 13 breaking and being damaged;

[0054] S3: At the same time, during the movement of the support table 7, it will also drive the limit table 2004 to move synchronously. Since the force receiving rod 2005 on the side wall of the limit table 2004 is fitted and embedded in the inclined first chute 23 opened on the side wall of the guide post 22, at this time, the force receiving rod 2005 will drive the limit table 2004 to move up and down reciprocally. The limit table 2004 drives the rotating rod 2001 to reciprocally rotate through the rotatably connected guide rod 2003. At this time, the arc-shaped tooth plate 2002 fixedly connected to the end of the rotating rod 2001 will rotate synchronously. The arc-shaped tooth plate 2002 will drive the transmission gear ring 19 to rotate synchronously. At this time, the transmission gear ring 19 will drive the transmission rod 15 to rotate synchronously through the rotating sleeve 18 and the fastening rod 17. And the transmission rod 15 will drive the cutting wire 13 to rotate synchronously through the sleeve 14 and the moving block 11, so that the cutting wire 13 can rotate by itself, thereby improving the cutting effect and preventing one side of the cutting wire 13 from continuously cutting, so as to reduce the risk of the cutting wire 13 breaking;

[0055] S4: When the cutting wire 13 cuts the aerated block blank, the cutting wire 13 will be subjected to the reverse pressure of the aerated block blank, so that the support platform 7 drives the guide column 22 to move relatively as a whole. At this time, the guide column 22 will drive the docking frame 27 to move synchronously, so that the docking frame 27 will further compress the pressure spring 29. When the reverse pressure on the cutting wire 13 is too large, in order to prevent the cutting wire 13 from breaking, the support platform 7 will drive the control frame 1205 on the storage tube 10 to move to the trigger position. At this time, the control frame 1205 will be able to squeeze on the outer wall of the opening of the door frame 3, and the control frame 1205 will drive the push The force teeth 1203 move synchronously, so that the thrust teeth 1203 can push the corresponding force block 1202 to move, and the force block 1202 will drive the corresponding positioning plate 1201 to move and compress the reset spring 1204. At the same time, the teeth of the positioning plate 1201 will move away from the moving block 11 to release the locking relationship, so that the cutting wire 13 can pull the moving block 11 to move in the storage tube 10, thereby reducing the risk of the cutting wire 13 being damaged due to the instantaneous excessive resistance of the aerated block blank. In the process of the moving block 11 moving to pull the tension spring 16, the teeth of the positioning plate 1201 are attached to the side wall of the moving block 11.

The method for using the aerated concrete block cutting machine according to claim 1, characterized in that: The operation method of the aerated block cutting machine is as follows: S1: The concrete aerated block blank is positioned on the base (1) by means of an existing fixture. When cutting, the user starts the servo motor (2) and the electric cylinder (4). The output screw of the servo motor (2) drives the gantry (3) to move toward the aerated block blank at a processing speed. The electric cylinder (4) drives the two loading frames (6) to move back and forth synchronously through the cross frame (5). The loading frames (6) drive the inner slide block (9) to move synchronously through the guide rail (8) and the support platform (7). The inner slide block (9) drives the fixedly connected storage cylinder (10) to move. The moving block (11) is locked in the storage cylinder (10). At the same time, both ends of the cutting wire (13) are fixedly connected to the corresponding moving block (11). The cutting wire (13) is in a tensioned state. At this time, the cutting wire (13) moves back and forth synchronously and rapidly to facilitate cutting of the aerated block blank. S2: When the support platform (7) drives the inner slider (9) to move back and forth along the guide column (22), the wavy second slide groove (24) on the guide column (22) applies pressure to the vertical rod (25), so that the vertical rod (25) can drive the inner slider (9) to move back and forth through the tension plate (26). At this time, the inner slider (9) drives the cutting wire (13) to move synchronously through the storage tube (10). The cutting wire (13) moves back and forth with a small movement amount directly facing the incision of the aerated block, so as to prevent the cutting wire (13) from being continuously pressed on the aerated block blank with excessive pressure, thereby reducing the risk of the cutting wire (13) being broken and damaged; S3: At the same time, the support platform (7) will also drive the limit platform (2004) to move synchronously during the movement. Since the force-bearing rod (2005) on the side wall of the limit platform (2004) is fitted and embedded in the inclined first sliding groove (23) provided on the side wall of the guide column (22), the force-bearing rod (2005) will drive the limit platform (2004) to move up and down reciprocatingly. The limit platform (2004) drives the rotating rod (2001) to rotate reciprocatingly through the rotatably connected guide rod (2003). At this time, the arc-shaped toothed plate fixedly connected to the end of the rotating rod (2001) (2002) will rotate synchronously, and the arc-shaped toothed plate (2002) will rotate the transmission toothed ring (19) synchronously. At this time, the transmission toothed ring (19) will drive the transmission rod (15) to rotate synchronously through the rotating sleeve (18) and the fastening rod (17), and the transmission rod (15) will drive the cutting wire (13) to rotate synchronously through the sleeve (14) and the moving block (11), so that the cutting wire (13) itself can rotate, thereby improving the cutting effect and preventing one side of the cutting wire (13) from being cut continuously, thereby reducing the risk of the cutting wire (13) breaking; S4: When the cutting wire (13) cuts the aerated block stock, the cutting wire (13) is subjected to the reverse pressure of the aerated block stock, so that the support platform (7) drives the guide column (22) to move relatively as a whole. At this time, the guide column (22) drives the docking frame (27) to move synchronously, so that the docking frame (27) further compresses the pressure spring (29). When the reverse pressure on the cutting wire (13) is too large, in order to prevent the cutting wire (13) from breaking, the support platform (7) drives the control frame (1205) on the storage tube (10) to move to the trigger position. At this time, the control frame (1205) can be pressed on the outer wall of the opening of the door frame (3), and the control frame (1205) drives the pusher (29). The force teeth (1203) move synchronously, so that the thrust teeth (1203) can push the corresponding force block (1202) to move, and the force block (1202) will drive the corresponding positioning plate (1201) to move to compress the return spring (1204). At the same time, the teeth of the positioning plate (1201) will move away from the moving block (11) to release the locking relationship, so that the cutting wire (13) can pull the moving block (11) to move in the storage tube (10), thereby reducing the risk of the cutting wire (13) being damaged due to the instantaneous excessive resistance of the aerated block blank. In the process of the moving block (11) moving to pull the tension spring (16), the teeth of the positioning plate (1201) are attached to the side wall of the moving block (11).
