[0015] A cutting method for alloy steel mold processing uses the above-mentioned numerical control sawing machine.

[0016] Compared with the prior art, the present invention provides a numerical control sawing machine and a cutting method for alloy steel mold processing, having the following beneficial effects: 1. For this numerical control sawing machine, after a section of the alloy steel mold is cut off, the moving mechanism can drive the mold moving block to move inside the movable clamping seat. When the mold moving block moves inside the movable clamping seat, it can drive the alloy steel mold to move forward in the state of clamping the alloy steel mold. After the alloy steel mold moves, the cutting mechanism cuts the alloy steel mold. By repeating this cycle, the alloy steel mold can be moved while keeping it fixed, thus avoiding repeated fixation of the alloy steel mold during multiple cuts and preventing the alloy steel mold from shifting during repeated fixation, which affects the cutting accuracy.

[0017] 2. For this numerical control sawing machine, during operation, the forward and reverse rotations of the clamping motor can drive the transmission screw to rotate synchronously.

When the clamping moving seat moves, it can drive the movable clamping seat to move synchronously. The position of the movable clamping seat is adjusted and controlled through the threaded connection between the clamping moving seat and the transmission screw. And when the mold moving block moves the alloy steel mold, it can also cooperate through the roller structure of the cooperative moving belt and the cooperative roller.

[0018] 3. For this numerical control sawing machine, after the mold moving block moves past the protrusion on the movable clamping seat, the limiting spring and the clamping plate spring rebound, and the clamping limiting plate and the block connecting rod move towards the center of the movable clamping seat. The mold clamping plate no longer contacts the alloy steel mold. Through the elastic structure of the connecting rod movable ring and the limiting spring cooperating with the protrusion on the movable clamping seat, the contact with the alloy steel mold can be released after the mold clamping plate moves the alloy steel mold, so that the alloy steel mold can be moved and cut in a cycle.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a numerical control sawing machine and a cutting method for alloy steel mold processing. Embodiment 1

[0023] Please refer to Figure 1 - Figure 9 , a numerical control sawing machine, including a device main body 1, a driving mechanism 2 is installed on the top of the device main body 1, a cutting mechanism 3 is installed on the top of the device main body 1, a clamping mechanism 4 is installed on the top of the device main body 1, an electrical cabinet 5 is installed outside the device main body 1, a debris collection port 6 is opened inside the device main body 1, a moving mechanism 7 is installed inside the clamping mechanism 4, and a mold moving clamp block 8 is installed inside the clamping mechanism 4; The clamping mechanism 4 includes a mold cutting table 41, a moving clamping seat 48 is movably installed outside the mold cutting table 41, a fixed clamping seat 49 is fixedly installed outside the mold cutting table 41, both the moving mechanism 7 and the mold moving clamp block 8 are installed inside the moving clamping seat 48, a chute and a protrusion are provided on one side of the moving clamping seat 48, the moving mechanism 7 can drive the mold moving clamp block 8 to move along the chute inside the moving clamping seat 48, and the mold moving clamp block 8 can contact the alloy steel mold when passing through the protrusion on the moving clamping seat 48. When the moving clamping seat 48 moves on the mold cutting table 41, it can drive the moving mechanism 7 and the mold moving clamp block 8 to move synchronously; When the moving clamping seat 48 drives the mold moving clamp block 8 on the mold cutting table 41, it can jointly clamp the alloy steel mold to be cut with the fixed clamping seat 49. The cutting mechanism 3 can cut the alloy steel mold on the clamping mechanism 4. The moving mechanism 7 can drive the mold moving clamp block 8 to move inside the moving clamping seat 48. The mold moving clamp block 8 can move inside the moving clamping seat 48 while keeping the alloy steel mold clamped. The mold moving clamp block 8 can continuously drive the alloy steel mold to move on the mold cutting table 41 under the drive of the moving mechanism 7.

[0024] During operation, first place the alloy steel mold to be cut on the mold cutting table 41. Then, drive the mold moving clamp block 8 and 009 to move on the mold cutting table 41 by moving the clamping seat 48, and jointly clamp the alloy steel mold to be cut by the mold moving clamp block 8 and the fixed clamping seat 49. After the alloy steel mold is fixed, the cutting mechanism 3 can be driven by the driving mechanism 2 to cut the alloy steel mold. After a section of the alloy steel mold is cut off, the moving mechanism 7 can drive the mold moving clamp block 8 to move inside the moving clamping seat 48. When the mold moving clamp block 8 moves inside the moving clamping seat 48, it can drive the alloy steel mold to move forward in the state of clamping the alloy steel mold. After the alloy steel mold moves, the cutting mechanism 3 can be used to cut the alloy steel mold again. By repeating this cycle, the alloy steel mold can be moved while keeping it fixed, thus avoiding repeatedly fixing the alloy steel mold during multiple cuts, and also preventing the alloy steel mold from shifting during repeated fixing, which affects the cutting accuracy. Embodiment 2

[0025] The difference from the above embodiment is as follows. Please refer to Figure 1 - Figure 9 , a clamping motor 42 is installed on the top of the mold cutting table 41. The driving end of the clamping motor 42 is installed with a motor roller 43. A transmission belt 44 is installed outside the motor roller 43. A clamping moving seat 47 is installed at the bottom of the moving clamping seat 48. A transmission screw 45 is rotatably installed outside the fixed clamping seat 49. One end of the transmission screw 45 is installed with a screw roller 46. A cooperative roller 410 is installed inside the fixed clamping seat 49. A cooperative moving belt 411 is installed outside the cooperative roller 410.

[0026] The screw roller 46 outside the transmission screw 45 is in transmission connection with the motor roller 43 on the driving end of the clamping motor 42 through the transmission belt 44; When the clamping motor 42 drives the motor roller 43 to rotate, it can drive the transmission screw 45 to rotate synchronously through the transmission connection between the transmission belt 44 and the screw roller 46.

[0027] The clamping moving seat 47 is slidably installed inside the mold cutting table 41, and the inside of the clamping moving seat 47 is in threaded connection with the outside of the transmission screw 45; When the transmission screw 45 rotates, it can drive the clamping moving seat 47 to move horizontally inside the mold cutting table 41. When the clamping moving seat 47 moves horizontally inside the mold cutting table 41, it can drive the moving clamping seat 48 to move synchronously on the top of the mold cutting table 41.

[0028] When it is necessary to fix the alloy steel mold, the clamping motor 42 can drive the motor roller 43 to rotate forward. When the motor roller 43 rotates forward, it can drive the screw roller 46 to rotate forward through the transmission belt 44. When the screw roller 46 rotates forward, it can drive the transmission screw 45 to rotate forward inside the mold cutting table 41. When the transmission screw 45 rotates forward, it can drive the clamping moving seat 47 to move inside the mold cutting table 41 in the direction of the fixed clamping seat 49 through the threaded connection with the clamping moving seat 47. When the clamping moving seat 47 moves, it can drive the moving clamping seat 48 to move synchronously. When the moving clamping seat 48 moves, it can drive the mold moving clamp 8 to contact the alloy steel mold, while the fixed clamping seat 49 contacts the alloy steel mold through the cooperative moving belt 411. When the mold moving clamp 8 drives the alloy steel mold to move on the mold cutting table 41, the cooperative moving belt 411 can rotate inside the fixed clamping seat 49 through the cooperative roller 410 to cooperate with the mold moving clamp 8 to move the position of the alloy steel mold. After the alloy steel mold is cut, the clamping motor 42 drives the motor roller 43 to rotate in the reverse direction. When the motor roller 43 rotates in the reverse direction, it can drive the transmission screw 45 to rotate in the reverse direction. When the transmission screw 45 rotates in the reverse direction, it can drive the clamping moving seat 47 to move away from the fixed clamping seat 49 through the threaded connection with the clamping moving seat 47. When the clamping moving seat 47 moves, it can drive the moving clamping seat 48 to move synchronously. The position of the moving clamping seat 48 is adjusted and controlled through the threaded connection between the clamping moving seat 47 and the transmission screw 45, and when the mold moving clamp 8 moves the alloy steel mold, it can also cooperate through the roller structure of the cooperative moving belt 411 and the cooperative roller 410. Embodiment III

[0029] The difference from the above embodiment is that, please refer to Figure 1 - Figure 9 The moving mechanism 7 includes a horizontal sliding groove 71, a hydraulic telescopic rod 74 and a vertical sliding groove 75. The horizontal sliding groove 71 is arranged at the bottom inside the moving clamping seat 48. The hydraulic telescopic rod 74 is installed outside the moving clamping seat 48. The vertical sliding groove 75 is arranged on the side wall inside the moving clamping seat 48. A horizontal sliding plate 72 is slidably installed inside the horizontal sliding groove 71. A transmission connecting rod 73 is connected to the outside of the horizontal sliding plate 72. A vertical sliding plate 76 is slidably installed inside the vertical sliding groove 75. Clamping block pushing seats 77 are installed on the outside of both the horizontal sliding plate 72 and the vertical sliding plate 76. A transmission connecting cable 78 is connected to the outside of the horizontal sliding plate 72. An upper pulley 79 is installed on the side wall inside the moving clamping seat 48. A lower pulley 710 is installed at the bottom inside the moving clamping seat 48.

[0030] The clamp block pushing seat 77 includes a rotating base 771 and a rotating limit block 773. The rotating base 771 and the rotating limit block 773 are installed on the outside of both the vertical sliding plate 76 and the horizontal sliding plate 72. A rotating shaft 772 is installed inside the rotating base 771. A clamp block pushing plate 774 is installed on the outside of the rotating shaft 772, and a limit torsion spring 775 is installed on the rotating shaft 772. The clamp block pushing plate 774 is rotationally connected to the rotating base 771 through the rotating shaft 772. The rotating limit block 773 can limit the rotation direction of the clamp block pushing plate 774, and the limit torsion spring 775 can drive the clamp block pushing plate 774 to rebound after the clamp block pushing plate 774 rotates.

[0031] The outside of the horizontal sliding plate 72 is connected to the movable end of the hydraulic telescopic rod 74 through a transmission connecting rod 73 passing through the movable clamping seat 48. One end of the transmission connecting cable 78 is connected to the outside of the horizontal sliding plate 72, and the other end of the transmission connecting cable 78 is connected to the vertical sliding plate 76 after passing through the upper pulley 79 and the lower pulley 710. When the movable end of the hydraulic telescopic rod 74 expands and contracts, it can drive the horizontal sliding plate 72 to move inside the horizontal sliding groove 71 through the transmission connecting rod 73. When the horizontal sliding groove 71 moves, it can drive the vertical sliding plate 76 to move synchronously through the transmission connecting cable 78. When the horizontal sliding plate 72 and the vertical sliding plate 76 move, they can drive the clamp block pushing seat 77 to move synchronously. When the clamp block pushing seat 77 moves, it can drive the mold moving clamp block 8 to move inside the movable clamping seat 48.

[0032] After the cutting mechanism 3 finishes cutting a section of the alloy steel mold, the hydraulic telescopic rod 74 contracts. When the hydraulic telescopic rod 74 contracts, it can drive the horizontal sliding plate 72 to move in the direction of the vertical chute 75. When the horizontal sliding plate 72 moves in the direction of the vertical chute 75, it can drive the mold moving clamp 8 in contact with it to move synchronously through the clamp pushing seat 77. When the mold moving clamp 8 moves, it can drive the alloy steel mold to move synchronously. When the horizontal sliding plate 72 moves in the direction of the vertical chute 75, the transmission connecting cable 78 can be relaxed. When the transmission connecting cable 78 is relaxed, the vertical sliding plate 76 can move downward along the vertical chute 75. After the alloy steel mold moves, the hydraulic telescopic rod 74 extends. When the hydraulic telescopic rod 74 extends, it can drive the horizontal sliding plate 72 to move away from the vertical chute 75. At this time, when the horizontal sliding plate 72 moves, it can pull the vertical sliding plate 76 to move upward through the transmission connecting cable 78. When the vertical sliding plate 76 moves upward, it can drive the mold moving clamp 8 in contact with it to move upward through the clamp pushing seat 77. When the horizontal sliding plate 72 moves away from the vertical chute 75, the clamp pushing plate 774 can rotate through the mold moving clamp 8. After the clamp pushing seat 77 passes through the mold moving clamp 8, the limiting torsion spring 775 can drive the clamp pushing plate 774 to rebound. Thus, when the hydraulic telescopic rod 74 drives the horizontal sliding plate 72 to reciprocate, the horizontal sliding plate 72 can drive the mold moving clamp 8 to move unidirectionally through the clamp pushing seat 77. Embodiment 4

[0033] The difference from the above embodiment is as follows. Please refer to Figure 1 - Figure 9 The mold moving clamp 8 includes a clamp connecting rod 81. The clamp connecting rod 81 is movably installed inside the moving clamping seat 48. An outer fixing ring 82 of the clamp connecting rod 81 is fixedly installed on the outside of the clamp connecting rod 81. A limiting spring 83 is installed outside the outer fixing ring 82. A connecting rod moving ring 84 is slidably installed on the outside of the clamp connecting rod 81. One end of the clamp connecting rod 81 is connected to a clamping limiting plate 85. A clamping plate spring 86 is installed inside the clamping limiting plate 85. A mold clamping plate 87 is slidably installed inside the clamping limiting plate 85; The mold clamping plate 87 is slidably connected to the inside of the clamping limiting plate 85 through the clamping plate spring 86.

[0034] The connecting rod moving ring 84 and the clamping limiting plate 85 are respectively located on the inner and outer sides of the moving clamping seat 48. The connecting rod moving ring 84 contacts the inner wall of the moving clamping seat 48. The outside of the clamping limiting plate 85 contacts the outside of the moving clamping seat 48. The outer fixing ring 82 and the connecting rod moving ring 84 are connected through the limiting spring 83; When the clamping limit plate 85 contacts the protrusion on the moving clamping seat 48, it can make the connecting rod movable ring 84 move towards the connecting rod fixed ring 82. When the mold clamping plate 87 contacts the alloy steel mold, it can make the mold clamping plate 87 move towards the clamping limit plate 85.

[0035] The chute opened on the side of the moving clamping seat 48 is divided into a horizontal section, a vertical section and an inclined section. The moving mechanism 7 can drive the mold moving block 8 to move from the starting point of the horizontal section of the chute on the moving clamping seat 48 to the vertex of the vertical section. When the mold moving block 8 is at the vertex of the vertical section, it can slide along the inclined section to the starting point of the horizontal section. When the mold moving block 8 moves along the horizontal section, the clamping limit plate 85 can contact the protrusion on the moving clamping seat 48. When the clamping limit plate 85 contacts the protrusion on the moving clamping seat 48, it can drive the clamping limit plate 85 and the clamp connecting rod 81 to move towards the outside of the moving clamping seat 48. At this time, the distance between the clamping limit plate 85 and the connecting rod movable ring 84 increases, causing the limit spring 83 to compress. And when the clamping limit plate 85 moves outwards, the mold clamping plate 87 contacts the alloy steel mold. During the gradual movement of the mold moving block 8, the clamping plate spring 86 gradually compresses and the mold clamping plate 87 gradually moves towards the clamping limit plate 85. After the mold moving block 8 moves past the protrusion on the moving clamping seat 48, the limit spring 83 and the clamping plate spring 86 rebound, and the clamping limit plate 85 and the clamp connecting rod 81 move towards the center of the moving clamping seat 48, and the mold clamping plate 87 no longer contacts the alloy steel mold. Through the elastic structure of the connecting rod movable ring 84 and the limit spring 83 cooperating with the protrusion on the moving clamping seat 48, it can release the contact with the alloy steel mold after the mold clamping plate 87 moves the alloy steel mold, so as to be able to cycle the movement and cutting of the alloy steel mold. Embodiment Five
