DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a CNC sawing machine and a cutting method for alloy steel mold processing. Example 1

[0040] See also Figure 1 - Figure 9 A CNC sawing machine includes a device body 1, a driving mechanism 2 is installed on the top of the device body 1, a cutting mechanism 3 is installed on the top of the device body 1, a clamping mechanism 4 is installed on the top of the device body 1, an electrical cabinet 5 is installed outside the device body 1, a debris collection port 6 is opened inside the device body 1, a moving mechanism 7 is installed inside the clamping mechanism 4, and a mold moving clamping block 8 is installed inside the clamping mechanism 4;

[0041] The clamping mechanism 4 includes a mold cutting table 41, a movable clamping seat 48 is movably installed on the outside of the mold cutting table 41, and a fixed clamping seat 49 is fixedly installed on the outside of the mold cutting table 41. The movable mechanism 7 and the mold movable clamping block 8 are both installed inside the movable clamping seat 48. A slide groove and a protrusion are provided on one side of the movable clamping seat 48. The movable mechanism 7 can drive the mold movable clamping block 8 to move along the slide groove inside the movable clamping seat 48. When the mold movable clamping block 8 passes through the protrusion on the movable clamping seat 48, it can contact the alloy steel mold. When the movable clamping seat 48 moves on the mold cutting table 41, it can drive the movable mechanism 7 and the mold movable clamping block 8 to move synchronously;

[0042] When the movable clamping seat 48 drives the mold moving clamping block 8 on the mold cutting table 41, it can clamp the alloy steel mold to be cut together with the fixed clamping seat 49. The cutting mechanism 3 can cut the alloy steel mold on the clamping mechanism 4. The movable mechanism 7 can drive the mold moving clamping block 8 to move inside the movable clamping seat 48. The mold moving clamping block 8 can move inside the movable clamping seat 48 while maintaining the clamping state of the alloy steel mold. The mold moving clamping block 8 can continue to drive the alloy steel mold to move on the mold cutting table 41 under the drive of the movable mechanism 7.

[0043] During work, the alloy steel mold to be cut is first placed on the mold cutting table 41, and then the mold moving clamping block 8 and 009 are driven to move on the mold cutting table 41 by the mobile clamping seat 48, and the alloy steel mold to be cut is clamped by the mold moving clamping block 8 and the fixed clamping seat 49. After the alloy steel mold is fixed, the driving mechanism 2 can drive the cutting mechanism 3 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 clamping block 8 to move inside the mobile clamping seat 48. When the mold moving clamping block 8 moves inside the mobile clamping seat 48, it can first drive the alloy steel mold forward in the state of clamping the alloy steel mold. After the alloy steel mold is moved, the alloy steel mold is cut by the cutting mechanism 3. In this way, the alloy steel mold can be moved while keeping the alloy steel mold fixed, thereby avoiding repeated fixation of the alloy steel mold when the alloy steel mold is cut multiple times, and can also prevent the alloy steel mold from offsetting during repeated fixation, affecting the cutting accuracy. Example 2

[0044] The difference from the above embodiment is that, please refer to Figure 1 - Figure 9 A clamping motor 42 is installed on the top of the mold cutting table 41, and a motor roller 43 is installed on the driving end of the clamping motor 42. A transmission belt 44 is installed on the outside of the motor roller 43. A clamping movable seat 47 is installed on the bottom of the movable clamping seat 48. A transmission screw 45 is installed on the outside of the fixed clamping seat 49. A screw roller 46 is installed on one end of the transmission screw 45. A cooperative roller 410 is installed inside the fixed clamping seat 49, and a cooperative moving belt 411 is installed on the outside of the cooperative roller 410.

[0045] The screw roller 46 on the outside of the transmission screw 45 is connected to the motor roller 43 on the driving end of the clamping motor 42 through the transmission belt 44;

[0046] When the clamping motor 42 drives the motor roller 43 to rotate, the transmission screw 45 can be driven to rotate synchronously through the transmission connection between the transmission belt 44 and the screw roller 46.

[0047] The clamping movable seat 47 is slidably mounted inside the mold cutting table 41 , and the interior of the clamping movable seat 47 is threadedly connected to the exterior of the transmission screw 45 ;

[0048] The rotation of the transmission screw 45 can drive the clamping movable seat 47 to move horizontally inside the mold cutting table 41. When the clamping movable seat 47 moves horizontally inside the mold cutting table 41, it can drive the movable clamping seat 48 to move synchronously on the top of the mold cutting table 41.

[0049] When the alloy steel mold needs to be fixed, the motor roller 43 can be driven to rotate forward by the clamping motor 42. When the motor roller 43 rotates forward, the screw roller 46 can be driven to rotate forward by 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 movable seat 47 to move inside the mold cutting table 41 toward the fixed clamping seat 49 through the threaded connection with the clamping movable seat 47. When the clamping movable seat 47 moves, it can drive the movable clamping seat 48 to move synchronously. When the movable clamping seat 48 moves, it can drive the mold movable clamping block 8 to contact the alloy steel mold, and the fixed clamping seat 49 contacts the alloy steel mold through the cooperative moving belt 411. When the mold movable clamping block 8 drives the alloy steel mold to move on the mold cutting table 41, the cooperative moving belt 411 can rotate and cooperate with the fixed clamping seat 49 through the cooperative roller 410. The mold moving clamp 8 moves the position of the alloy steel mold. After the alloy steel mold cutting is completed, the motor roller 43 is driven to rotate in the opposite direction by the clamping motor 42. When the motor roller 43 rotates in the opposite direction, the transmission screw 45 can be driven to rotate in the opposite direction. When the transmission screw 45 rotates in the opposite direction, the clamping moving seat 47 can be driven 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, the movable clamping seat 48 can be driven to move synchronously. The position of the movable clamping seat 48 is adjusted and controlled by the threaded connection between the clamping moving seat 47 and the transmission screw 45. When the mold moving clamp 8 moves the alloy steel mold, it can also cooperate with the roller structure of the cooperative moving belt 411 and the cooperative roller 410. Example 3

[0050] The difference from the above embodiment is that, please refer to Figure 1 - Figure 9 The moving mechanism 7 includes a horizontal slide 71, a hydraulic telescopic rod 74 and a vertical slide 75. The horizontal slide 71 is arranged at the bottom inside the mobile clamping seat 48, the hydraulic telescopic rod 74 is installed on the outside of the mobile clamping seat 48, and the vertical slide 75 is arranged on the side wall inside the mobile clamping seat 48. The horizontal slide 71 is internally slidably installed with a horizontal sliding plate 72, and the outside of the horizontal sliding plate 72 is connected to a transmission connecting rod 73. The vertical slide 75 is internally slidably installed with a vertical sliding plate 76. The outside of the horizontal sliding plate 72 and the vertical sliding plate 76 are both installed with a clamping block pushing seat 77, and the outside of the horizontal sliding plate 72 is connected to a transmission connecting rope 78. An upper pulley 79 is installed on the side wall inside the mobile clamping seat 48, and a lower pulley 710 is installed at the bottom inside the mobile clamping seat 48.

[0051] The clamping 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 the vertical sliding plate 76 and the horizontal sliding plate 72. The rotating base 771 is internally mounted with a rotating shaft 772. The rotating shaft 772 is externally mounted with a clamping block pushing plate 774. The rotating shaft 772 is mounted with a limiting torsion spring 775.

[0052] The clamping block pushing plate 774 is rotatably connected to the rotating base 771 through the rotating shaft 772. The rotating limit block 773 can limit the rotation direction of the clamping block pushing plate 774. The limiting torsion spring 775 can drive the clamping block pushing plate 774 to rebound after the clamping block pushing plate 774 rotates.

[0053] The outside of the horizontal sliding plate 72 is connected to the movable end of the hydraulic telescopic rod 74 via a transmission connecting rod 73 passing through the movable clamping seat 48. One end of a 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 passes through an upper pulley 79 and a lower pulley 710 and is connected to the vertical sliding plate 76.

[0054] When the movable end of the hydraulic telescopic rod 74 is extended or retracted, the horizontal sliding plate 72 can be driven to move inside the horizontal slide groove 71 through the transmission connecting rod 73. When the horizontal slide groove 71 moves, the vertical sliding plate 76 can be driven to move synchronously through the transmission connecting rope 78. When the horizontal sliding plate 72 and the vertical sliding plate 76 move, they can drive the clamping block pushing seat 77 to move synchronously. When the clamping block pushing seat 77 moves, it can drive the mold moving clamping block 8 to move inside the movable clamping seat 48.

[0055] After the cutting mechanism 3 has finished 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 slide groove 75. When the horizontal sliding plate 72 moves in the direction of the vertical slide groove 75, it can drive the mold moving clamping block 8 in contact with it to move synchronously through the clamping block pushing seat 77. When the mold moving clamping block 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 slide groove 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 slide groove 75. After the alloy steel mold is moved, the hydraulic telescopic rod 74 extends. When the hydraulic telescopic rod 74 extends, it can drive When the horizontal sliding plate 72 moves in the direction away from the vertical sliding groove 75, the horizontal sliding plate 72 can pull the vertical sliding plate 76 upward through the transmission connecting rope 78 when it moves. When the vertical sliding plate 76 moves upward, the mold moving clamp 8 in contact with it can be driven to move upward through the clamp pushing seat 77. When the horizontal sliding plate 72 moves in the direction away from the vertical sliding groove 75, the clamp pushing plate 774 can rotate to pass 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, so that 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. Example 4

[0056] The difference from the above embodiment is that, please refer to Figure 1 - Figure 9 The mold moving clamping block 8 includes a clamping block connecting rod 81, which is movably installed inside the mobile clamping seat 48. A connecting rod fixing ring 82 is fixedly installed on the outside of the clamping block connecting rod 81, and a limiting spring 83 is installed on the outside of the connecting rod fixing ring 82. A connecting rod movable ring 84 is slidably installed on the outside of the clamping block connecting rod 81. One end of the clamping block connecting rod 81 is connected to a clamping limit plate 85, and a clamping plate spring 86 is installed inside the clamping limit plate 85. A mold clamping plate 87 is slidably installed inside the clamping limit plate 85.

[0057] The mold clamping plate 87 is slidably connected to the inside of the clamping limit plate 85 through the clamping plate spring 86.

[0058] The connecting rod movable ring 84 and the clamping limit plate 85 are respectively located on the inner and outer sides of the movable clamping seat 48. The connecting rod movable ring 84 contacts the inner wall of the movable clamping seat 48, and the outer side of the clamping limit plate 85 contacts the outer side of the movable clamping seat 48. The connecting rod fixed ring 82 and the connecting rod movable ring 84 are connected by a limit spring 83.

[0059] When the clamping limit plate 85 contacts the protrusion on the movable clamping seat 48, the connecting rod movable ring 84 can move toward the connecting rod fixed ring 82. When the mold clamping plate 87 contacts the alloy steel mold, the mold clamping plate 87 can move toward the clamping limit plate 85.

[0060] The slide groove opened on the side of the movable 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 clamp 8 to move along the starting point of the horizontal section of the slide groove on the movable clamping seat 48 to the top of the vertical section, and the mold moving clamp 8 can slide along the inclination to the starting point of the horizontal section when it is at the top of the vertical section. When the mold moving clamp 8 moves along the horizontal section, the clamping limit plate 85 can contact the protrusion on the movable clamping seat 48. When the clamping limit plate 85 contacts the protrusion on the movable clamping seat 48, it can drive the clamping limit plate 85 and the clamp connecting rod 81 to move to the outside of the movable clamping seat 48. At this time, the distance between the clamping limit plate 85 and the connecting rod active ring 84 increases, causing the limit spring 83 to be compressed, and when the clamping limit plate 85 moves toward When moving outward, the mold clamping plate 87 contacts the alloy steel mold. When the mold moving clamping block 8 gradually moves, the clamping plate spring 86 gradually compresses the mold clamping plate 87 and gradually moves toward the clamping limit plate 85. After the mold moving clamping 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 clamping block connecting rod 81 move toward the center of the moving clamping seat 48. 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 and the protrusion on the moving clamping seat 48, the mold clamping plate 87 can release the contact with the alloy steel mold after the mold clamping plate 87 completes the movement of the alloy steel mold, so that the alloy steel mold can be moved and cut cyclically. Example 5

[0062] During operation, the alloy steel mold to be cut is first placed on the mold cutting table 41, and then the mold moving clamping block 8 and the fixed clamping seat 49 are driven by the movable clamping seat 48 to fix the alloy steel mold;

[0063] Then the driving mechanism 2 drives the cutting mechanism 3 to cut the alloy steel mold;

[0064] After the cutting is completed, the moving mechanism 7 drives the mold moving clamp 8 to move, thereby driving the alloy steel mold to move on the mold cutting table 41;

[0065] After the movement is completed, the alloy steel mold is cut again by the cutting mechanism 3.
