Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and in particular to a cutting device for autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks have a unit volume weight that is one-third that of clay bricks, thermal insulation performance that is 3-4 times that of clay bricks, sound insulation performance that is twice that of clay bricks, impermeability performance that is more than twice that of clay bricks, and fire resistance performance that is 6-8 times that of reinforced concrete. The masonry strength of AAC blocks is about 80% of the strength of the blocks themselves (compared to 30% for red bricks). AAC blocks also have excellent construction characteristics. They can be produced in factories in various specifications and can be sawed, planed, drilled, and nailed like wood. To ensure that the size of the blocks meets construction requirements, cutting devices are needed to cut the blocks into the required sizes.

[0003] L-shaped blocks are a special type of building block, widely used in various construction scenarios due to their unique L-shaped structure. U-shaped blocks are widely used in building and civil engineering, especially suitable for scenarios requiring concealed pipelines, structural reinforcement, or rapid construction to meet the needs of block splicing. However, current cutting devices can only cut blocks into block shapes, and cannot cut them into L-shaped or U-shaped shapes according to actual construction needs. They also lack the function of drilling holes in the blocks, requiring subsequent secondary processing of the cut blocks using other processing equipment, which is cumbersome and reduces the processing efficiency of the blocks. Summary of the Invention

[0004] This invention discloses an autoclaved aerated concrete block cutting device, which solves the problems that the cutting device cannot cut the blocks into L-shaped or U-shaped shapes according to the actual needs of construction, and also does not have the function of drilling holes in the blocks. It also requires the use of other processing equipment to perform secondary processing on the cut blocks, which is cumbersome.

[0005] To solve the above-mentioned technical problems, the present invention specifically adopts the following technical solution:

[0006] A cutting device for autoclaved aerated concrete (AAC) blocks includes a worktable with an opening. A connecting shell is fixed on the worktable, and an electric telescopic rod is installed inside the connecting shell. A first motor is installed at the telescopic end of the electric telescopic rod, and a disc is fixed on the shaft of the first motor. A cutting disc is detachably connected to the disc. A connecting post is fixed on the disc, passing through a hole at the center of the cutting disc's axis. A drill bit is installed at the other end of the connecting post. A rotatably connected cylinder is fitted onto the connecting post, and a screw threadedly connected to the connecting post is detachably connected to the cylinder. A connecting plate is fixed at the fixed end of the electric telescopic rod, and a second motor is installed below the connecting plate. A cutting wire is installed on the shaft of the second motor, and the other end of the cutting wire is wound around the cylinder. A locking component is provided on the connecting plate to fix the cylinder and keep it stationary. A conveying component is provided inside the connecting shell to drive the electric telescopic rod to move laterally and backward.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] After placing the block on the workbench, the electric telescopic rod can be used to move the cutting disc laterally, aligning the cutting disc with the part of the block that needs to be cut. Then, the electric telescopic rod drives the cutting disc downward to cut the block, and the cut blocks are promptly transferred. When the block needs to be cut into an L-shape, first move the cutting disc downward to cut the part of the block that needs to be removed. Then, connect the screw to the connecting column threaded together. Next, move the cutting disc away from the cutting line, aligning the cutting line with one side of the block, and adjust the height of the cutting line. Then, repeatedly rotate the first and second motors forward and reverse, driving the cutting line to move laterally closer to the part of the block that needs to be removed. The cutting line can cut off the part of the block that needs to be removed, cutting the block into an L-shape; subsequently, the cutting line and the cutting disc work together to cut the block into a U-shape; when drilling is required, the screw is separated from the connecting post, and the locking component locks the cylinder, preventing the cylinder from rotating with the connecting post. Then, the end of the drill bit aligns with one side of the block, allowing drilling to be performed. This invention can cut blocks into several small blocks, or into L-shapes or U-shapes, and can also drill holes in the blocks. It eliminates the need for workers to transfer the cut blocks and then use other equipment for secondary processing, thus improving the processing efficiency of the blocks.

[0018] The specific content of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the present invention provides a cutting device for autoclaved aerated concrete blocks, including a workbench 1 with an opening 11. A connecting shell 2 is fixed on the workbench 1, and an electric telescopic rod 3 is provided inside the connecting shell 2. A first motor 31 is provided at the telescopic end of the electric telescopic rod 3. A disc 32 is fixed on the shaft of the first motor 31, and a cutting disc 4 is detachably connected to the disc 32. A connecting post 33 is fixed on the disc 32, passing through a hole at the center of the cutting disc 4. A drill bit 34 is provided at the other end of the connecting post 33. A sleeve is fitted on the connecting post 33. A rotating cylinder 35 is provided, and a screw 36, detachably connected to a connecting post 33, is threaded onto the cylinder 35. A connecting plate 5 is fixed to the fixed end of the electric telescopic rod 3. A second motor 54 is provided below the connecting plate 5, and a cutting wire 56 is provided on the shaft of the second motor 54. The other end of the cutting wire 56 is wound around the cylinder 35. A locking component is provided on the connecting plate 5 to fix the cylinder 35 and keep it stationary. A conveying component is provided inside the connecting housing 2 to drive the electric telescopic rod 3 to move laterally and backward. After the block 10 is placed, the conveying component drives the cutting disc 4 to move laterally through the electric telescopic rod 3, so that the cutting disc 4 is moved directly above the part of the block 10 that needs to be cut. Then, the electric telescopic rod 3 drives the first motor 31 to move the cutting disc 4 downward. The first motor 31 drives the disc 32 to rotate the cutting disc 4, cutting the block 10. Subsequently, the block 10 can be cut into several small rectangular pieces by the lateral movement of the electric telescopic rod 3.

[0020] When it is necessary to cut the block 10 into an L-shape, the cutting disc 4 can be moved downwards to first vertically cut the portion of the block 10 that needs to be removed, but without completely cutting off the block 10. Then, the cutting disc 4 is restored; and then the electric telescopic rod 3 is driven forward by the conveying assembly (to... Figure 1The orientation shown in the image is adjusted so that the cutting line 56 (which is a diamond cutting line) aligns with one side of the block 10, and the height of the cutting line 56 is adjusted. The bottom of the cutting disc 4 passes through the opening 11. The inner side of the cylinder 35 is rotatably connected to the connecting column 33 via a bearing. Both the first motor 31 and the second motor 54 are servo motors. The operator then threads the screw 36 to the connecting column 33 (the connecting column 33 has a screw hole that matches the screw 36), so that the connecting column 33 can drive the cylinder 35 to rotate. When the first motor 31 and the second motor 54 rotate, the cylinder 35 rotates. The shaft of the second motor 54 rotates repeatedly in small increments forward and reverse, the cutting line 56 runs, and the conveying component drives the electric telescopic rod 3 to move laterally. After the cutting line 56 moves along with the connecting plate 5, when the cutting line 56 comes into contact with the block 10, it can cut the part of the block 10 that needs to be removed, cutting the block 10 into an L-shape. When it is necessary to cut the block 10 into several L-shaped pieces, the cutting disc 4 can first cut the block 10 into several rectangular pieces, and then the cutting disc 4 vertically cuts the part that needs to be removed on each rectangular piece. Then, the cutting line 56 can be used to make horizontal cuts.

[0021] When it is necessary to cut the block 10 into a U-shape, the cutting disc 4 is moved downward to cut the block 10, but not completely severing it. The cutting disc 4 is then moved upward to return to its original position and moved laterally to the designated position. The cutting disc 4 is then moved downward again to cut the block 10, again without completely severing it. The cutting line 56 is then moved directly above the block 10 and then moved downward to the cut in the block 10. The cutting line 56 then runs and moves laterally to cut the portion of the block 10 that needs to be removed, thus forming a U-shape. Through the cooperation of the cutting disc 4 and the cutting line 56, the block 10 can also be cut into other shapes. When cutting the block 10 into an L-shape, the cutting line 56 moves from left to right; when cutting the block 10 into a U-shape, the cutting line 56 moves from right to left, ensuring that both sides of the cutting line 56 can be used.

[0022] When drilling is required on block 10, the screw 36 is separated from the connecting post 33, and the locking assembly locks the cylinder 35 so that the cylinder 35 no longer rotates with the connecting post 33; the cutting disc 4 is positioned on one side of block 10, and then the cutting disc 4 is activated so that the disc 32 drives the drill bit 34 to rotate through the connecting post 33, and the drill bit 34 moves laterally to facilitate drilling of block 10; after drilling is completed on block 10, the cutting disc 4 cuts block 10 off; the electric telescopic rod 3 can be a three-section telescopic rod.

[0023] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the locking assembly includes a first automatic telescopic rod 51 fixed to the bottom of the connecting plate 5. A magnet 52, which can contact the top of the cylinder 35, is fixed to the telescopic end of the first automatic telescopic rod 51. The cylinder 35 is made of steel. A rotating rod 55 is fixed to the shaft of the second motor 54, and one end of the cutting wire 56 is wound around the rotating rod 55. When the cylinder 35 does not need to rotate, the first automatic telescopic rod 51 can be activated to move the magnet 52 downwards to contact the cylinder 35, attracting the cylinder 35 and limiting its movement, preventing the cylinder 35 from rotating with the connecting column 33. When the cylinder 35 needs to rotate repeatedly in small increments in both directions, the magnet 52 can be separated from the cylinder 35.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a support platform 6 for placing blocks 10 is slidably connected to the top of the workbench 1. The support platform 6 has a discharge port 61. Both sides of the support platform 6 are fixed with baffles 62 slidably connected to the workbench 1. A second automatic telescopic rod 63 located inside the connecting shell 2 is fixed to one baffle 62. A push plate 64 is fixed to the telescopic end of the second automatic telescopic rod 63. Both sides of the connecting shell 2 have entrances for the baffles 62 to enter. Another support platform 6 is fixed to the side of the baffle 62 with the second automatic telescopic rod 63 away from the push plate 64. A third automatic telescopic rod 65 for driving the two support platforms 6 to alternately enter the connecting shell 2 is fixed to the connecting shell 2. There are three baffles 62, with two support platforms 6 fixed to the sides of the central baffle 62 (e.g.,...). Figure 2 (as shown in the image), located on the right side (with) Figure 1(As shown in the diagram) Two baffles 62 are respectively fixed with second automatic telescopic rods 63. The telescopic end of the third automatic telescopic rod 65 is fixed to the connecting rod on one of the baffles 62 (located on the leftmost baffle 62) via a connecting block. A slider is fixed to the bottom of the baffle 62, and a slide rail adapted to the slider is opened on the top of the worktable 1. After the block 10 is placed on one support platform 6, the third automatic telescopic rod 65 is activated to drive the support platform 6 into the connecting shell 2, and the cutting of the block 10 can begin. At the same time, the operator can place the block 10 to be processed on the other support platform 6. The two support platforms 6 alternately enter the connecting shell 2 to facilitate loading and unloading without long downtime, thus improving efficiency. To improve the processing efficiency of the block 10, the top of the support platform 6 is provided with several slots for the cutting disc 4 to enter, so that the cutting disc 4 can completely cut the block 10. When the block 10 is placed on the support platform 6, the second automatic telescopic rod 63 can be activated to drive the push plate 64 to move, so that the block 10 contacts the push plate 64 (the two second automatic telescopic rods 63 are independently controlled by external control panels), thus completing the positioning of the block 10. The setting of the connecting shell 2 can prevent the debris from flying everywhere when the block is cut, so that the debris can only be discharged through the opening 11 at the bottom of the worktable 1. The extension and retraction of the second automatic telescopic rod 63 is fixed to the push plate 64 through the floating joint, and the push plate 64 is fixed with a limiting rod that penetrates the baffle 62.

[0025] like Figure 2 , Figure 3 and Figure 8As shown, a hydraulic cylinder 7 is fixed inside the connecting shell 2. The telescopic end of the hydraulic cylinder 7 is fixed with a first conveying unit 71 that is slidably connected to the inner wall of the connecting shell 2. A moving plate 72 is fixed on the conveying surface of the first conveying unit 71 by an L-shaped plate. Two clamping plates 73 that are symmetrical in front and behind are slidably connected to the bottom of the moving plate 72. A fourth automatic telescopic rod 74 for driving the two clamping plates 73 to move closer to each other is fixed on the moving plate 72. When the cutting disc 4 cuts the block 10, the hydraulic cylinder 7 drives the first conveying unit 71 to move downwards. After adjusting the height of the moving plate 72, the conveying surface of the first conveying unit 71 drives the moving plate 72 to approach the block 10 via the L-shaped plate. This positions the part of the block 10 to be cut between the two clamping plates 73. Then, two fourth automatic telescopic rods 74 (two rods in total, each fixed to the bottom of the moving plate 72, with their telescopic ends fixed to the sides of the two clamping plates 73 away from each other) drive the two clamping plates 73 to move closer together, clamping and securing the block 10 to prevent it from shaking during cutting. After the block 10 is cut, the two clamping plates 73 clamp the cut block 10, and then the first conveying unit 71 drives the moving plate 72 towards the unloading direction. After the cutting block 10 is positioned directly above the discharge port 61, the extension end of the hydraulic cylinder 7 drives the first conveying unit 71 to move downwards. This causes the two clamping plates 73 to carry the block 10 through the discharge port 61 and the opening 11 in sequence, thus completing the automatic unloading of the block 10 without the need for manual unloading by the operator. Rubber pads are fixed to the opposite surfaces of the two clamping plates 73 to increase the friction with the block 10. The two fourth automatic telescopic rods 74 adopt master-slave follow control and are used in conjunction with a dual-axis synchronous controller (the dual-axis synchronous controller is not shown in the figure and is a very mature existing technology, so it will not be described in detail here). The two hydraulic cylinders 7 operate synchronously using a flow divider and combiner valve (a dedicated flow divider and combiner valve (or synchronous valve) is used to distribute the flow rate pumped from one oil source to the two hydraulic cylinders on an average (or in a fixed proportion) basis).

[0026] like Figure 2 As shown, the conveying assembly includes a second conveying unit 21 fixed to the top of the connecting shell 2. A movable frame 22, slidably connected to the connecting shell 2, is fixed to the conveying surface of the second conveying unit 21 via a fixing plate. A third motor 23 is fixed to the movable frame 22, and a lead screw 24 is fixed to the shaft of the third motor 23. A movable block 25, slidably connected to the inner wall of the movable frame 22, is threaded onto the lead screw 24. The fixed end of the electric telescopic rod 3 is connected to the movable block 25. The movable frame 22 is fixed with a sliding block slidably connected to the top of the connecting shell 2. After the second conveying unit 21 is activated, the movable frame 22 can be driven to move forward or backward (to...). Figure 1(As shown in the diagram), the sliding block can increase the stability of the moving frame 22 when it moves; the third motor 23 is a servo motor. After the third motor 23 is started, it can drive the lead screw 24 to rotate. The lead screw 24 is rotatably connected to the inside of the moving frame 22; after the lead screw 24 rotates, the moving block 25 can drive the electric telescopic rod 3 to move laterally.

[0027] like Figure 2 and Figure 4 As shown, the telescopic end of the electric telescopic rod 3 is fixed with a fixing block, and the bottom of the fixing block is fixed with a protective frame that covers and fixes the main body of the first motor 31; the cutting disc 4 is fixed to the disc 32 by bolts, and a threaded cylinder that is threadedly connected to the drill bit 34 is fixed on the connecting column 33. The protective frame can protect the first motor 31, and at the same time, the operator can separate the drill bit 34 from the threaded cylinder and replace it with a different drill bit 34 according to the drilling requirements of the block 10.

[0028] like Figure 2 and Figure 5 As shown, a storage shell 53 is fixed to the top of the connecting plate 5, and a nozzle penetrating the bottom of the storage shell 53 is connected to the bottom of the connecting plate 5. A flexible hose penetrating the connecting shell 2 is connected to the storage shell 53. The flexible hose is connected to an external water pump, which allows water to enter the storage shell 53, and the nozzle sprays out water mist, which can cool the cutting line 56 and the cutting disc 4, and also reduce dust in the connecting shell 2.

[0029] like Figure 1 and Figure 2 As shown, a connecting frame 8 covering the opening 11 is fixed to the bottom of the workbench 1. A T-shaped fixing rod 81 is fixed inside the connecting frame 8, and a bearing block 82 that contacts the bottom of the bearing platform 6 is fixed to the top of the fixing rod 81. The connecting frame 8 can limit dust and debris, ensuring that dust and debris can only fall downwards, facilitating the collection of dust and debris. When the bearing block 82 and the fixing rod 81 are in contact with the bottom of the bearing platform 6, the stability of the bearing platform 6 can be increased.

[0030] like Figure 1As shown, the third automatic telescopic rod 65 has a telescopic rod 9 with its fixed end fixed to the connecting shell 2 above it. The telescopic end of the telescopic rod 9 is fixed to the connecting block. The fixed end of the third automatic telescopic rod 65 is fixed with a bearing plate that is fixed to the connecting shell 2. A door panel 26 is hinged to one side of the connecting shell 2. After the third automatic telescopic rod 65 is activated, the telescopic end of the telescopic rod 9 moves accordingly. The telescopic end of the third automatic telescopic rod 65 is connected to the connecting block through a floating joint, ensuring the normal operation of the third automatic telescopic rod 65. The telescopic end of the electric telescopic rod 3 is also fixed to the protective frame through a floating joint. The bottom of the moving block 25 is also equipped with a telescopic rod 9, and the telescopic end of the telescopic rod 9 is fixed to the fixed block. The telescopic end of the first automatic telescopic rod 51 is fixed to the magnet 52 through a T-shaped plate. The telescopic end of the first automatic telescopic rod 51 is connected to the T-shaped plate through a floating joint. The bottom of the connecting plate 5 is also fixed with a telescopic rod 9, and the telescopic end of the telescopic rod 9 is fixed to the T-shaped plate. The staff can open the door panel 26 to inspect the components inside the connecting shell 2.

[0031] All electrical components in this application are electrically connected to an external control panel and a power supply. The control method in this application is through an external control panel. The control circuit of the external control panel can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
