Description

Technical Field

[0001] This utility model relates to the technical field of aerated concrete block cutting devices, specifically to an aerated concrete block brick cutting device. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight building material with excellent thermal insulation properties, and are widely used in building wall engineering. In actual construction, AAC blocks often need to be cut to size according to site requirements to meet the needs of different masonry scenarios.

[0003] However, existing aerated concrete block cutting technology has the following problems. Since large cutting machines mostly adopt a fixed structure, they are suitable for centralized processing in factories, but cannot meet the needs of flexible adjustment of cutting size on the construction site. They are particularly impractical in small-scale operations or narrow spaces. Therefore, workers often use hand saws or simple cutting tools during construction. However, this brick cutting method is labor-intensive and it is difficult to guarantee the quality of brick cutting. It is easy to cause the cut surface to be tilted and rough, which affects the quality of subsequent masonry and leads to material waste. Therefore, a device is needed to solve the above problems. Utility Model Content

[0010] Optionally, a connecting plate is fixedly connected to one side of the column, and the clamping mechanism includes a threaded rod, a lifting plate, and an upper cutter detachably connected to the lower surface of the lifting plate. The lifting plate is located on one side of the column and is guided to the column. The threaded rod passes through the connecting plate and is threaded to the connecting plate.

[0016] This utility model provides an aerated concrete block cutting device. Through the coordinated arrangement of a lifting plate, a lower cutting blade, and a drive mechanism, it can cut aerated concrete blocks from the bottom, facilitating processing into the required dimensions. With the aid of an avoidance groove, the cutting blade's obstruction of the aerated concrete block in the direction of movement is reduced after it is retracted into the base plate. Furthermore, the clamping mechanism can fix the aerated concrete block above, reducing its wobbling during cutting and resulting in a smoother cut surface. A support rod and clamping mechanism on one side of the base plate can adjust the orientation of the aerated concrete block, ensuring it is perpendicular to the lower cutting blade. This reduces deviations in cutting dimensions caused by placement errors, improving cutting accuracy. The detachable connection between the lower cutting blade and the lifting plate allows for quick replacement of the lower cutting blade after prolonged use, maintaining cutting efficiency and reducing uneven cuts caused by a dull blade.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: an aerated concrete block cutting device, including a base plate 1, a column 2 and a drive mechanism. The column 2 is fixedly connected to the upper surface of the base plate 1. A clearance groove 3 extending in the width direction is provided in the middle of the upper surface of the base plate 1. A liftable lifting plate 4 is provided inside the clearance groove 3. A lower cutter 5 is detachably connected to the upper surface of the lifting plate 4. The drive mechanism is located on one side of the column 2 to drive the lifting plate 4 to move.

[0025] The top of the column 2 is also equipped with a pressing mechanism that corresponds to the lifting plate 4 above and below to press the air block.

[0026] A support rod 6 is provided on one side of the upper surface of the base plate 1, and a clamping mechanism is provided in the middle of the support rod 6 to adjust the angle of the air block.

[0027] After the aerated concrete block is placed on the base plate 1, the lifting plate 4 is driven to move upward, so that the lower cutter 5 on the lifting plate 4 cuts the aerated concrete block to the required size. The clamping mechanism at the top of the column 2 can press the aerated concrete block from above, making the cut smoother during cutting. The clamping mechanism adjusts the angle of the aerated concrete block to ensure that the newly cut cut is perpendicular to the original edge of the aerated concrete block during the cutting process, so that it is more compact in subsequent masonry and reduces waste caused by the tilt of the cut.

[0028] In this embodiment, as a preferred option, a through groove 7 is provided at the bottom of the column 2. The two ends of the lifting plate 4 pass through the through groove 7, and the through groove 7 guides and limits the ends of the lifting plate 4 vertically. A driven gear 8 is rotatably connected to one end of the lifting plate 4 that passes through the through groove 7. The driving mechanism includes a driving rod 9, a driving gear 10, and a transmission chain 11. The driving rod 9 is rotatably connected to the top of the column 2 and passes through the column 2. The driving gear 10 is fixedly connected to the outside of the column 2 through which the driving rod 9 passes. The transmission chain 11 is fixedly connected to the outer surface of the driving gear 10 and meshes with the driven gear 8.

[0029] Both ends of the lifting plate 4 extend into the through groove 7, allowing the lifting plate 4 to move up and down along the through groove 7. When the drive rod 9 is rotated, the drive rod 9 drives the drive gear 10 at one end to rotate. The transmission chain 11 is fixedly connected to the drive gear 10. When the drive gear 10 rotates, it pulls the transmission chain 11 to move. The bottom of the transmission chain 11 meshes with the driven gear 8. When the transmission chain 11 moves upward, it simultaneously drives the driven gear 8 to rotate and move upward, thereby causing the driven gear 8 to move the lifting plate 4 on the inner wall upward, so that the lower cutter 5 above the lifting plate 4 cuts the gas block. After the cutting is completed, the drive rod 9 is rotated in the opposite direction to lower the lifting plate 4. The drive rod 9 is equipped with an operating handle, which makes it more convenient to rotate the drive rod 9.

[0030] In this embodiment, as a preferred option, a connecting plate 12 is fixedly connected to one side of the column 2. The clamping mechanism includes a threaded rod 13, a lifting plate 14, and an upper cutter 15 detachably connected to the lower surface of the lifting plate 14. The lifting plate 14 is located on one side of the column 2 and is guided to the column 2. The threaded rod 13 passes through the connecting plate 12 and is threaded to the connecting plate 12. The bottom of the threaded rod 13 is rotatably connected to the lifting plate 14. The upper cutter 15 and the lower cutter 5 are arranged vertically and vertically at intervals.

[0031] The column 2 has a notch, and the lifting plate 14 can move up and down within the notch. The notch restricts the movement direction of the lifting plate 14 to prevent it from rotating. When the threaded rod 13 is rotated, it drives the bottom lifting plate 14 to move down and press the aerated block above it, improving the stability of the brick cutting process and reducing the shaking of the aerated block. At the same time, the bottom of the lifting plate 14 and the top of the lifting plate 4 are respectively equipped with an upper cutter 15 and a lower cutter 5. With the cooperation of the two cutters, the cut surface can be made flatter. The upper cutter 15 plays a positioning role and can be replaced after a long period of use.

[0032] In this embodiment, as a preferred solution, the clamping mechanism includes an adjusting rod 16, a sleeve 17, and a clamping plate 18. The adjusting rod 16 is rotatably mounted on the top of the support rod 6. The outer surface of the adjusting rod 16 is provided with two sections of threads in opposite directions. There are two sleeves 17, which are threadedly connected to both ends of the adjusting rod 16. The clamping plate 18 is fixedly connected to the lower surface of the sleeve 17 to adjust the direction of the air block. The inner wall of the support rod 6 is provided with a guide rod 23, which passes through the clamping plate 18 to limit the movement direction of the clamping plate 18. The clamping plate 18 is arranged in an inverted T shape, and guide wheels 19 are provided on both sides of the bottom of the clamping plate 18 to reduce friction with the air block.

[0033] Two sleeves 17 engage with two opposite threads on the adjusting rod 16. When the adjusting rod 16 is rotated, the sleeves 17 on both sides move towards the middle or outwards simultaneously. When the sleeves 17 on both sides move towards the middle, the clamping plates 18 at the bottom of the sleeves 17 also move towards the middle, thereby clamping the air block in the middle and adjusting the tilted air block to be perpendicular to the cutter. The guide wheels 19 on both sides can reduce the friction between the air block and the air block, making it smoother when adjusting the direction of the air block. The clamping plates 18 are arranged in an inverted T shape, which extends the distance between the guide wheels 19 on both sides, making it more accurate when adjusting the direction of the air block.

[0034] In this embodiment, as a preferred option, a scale 20 is provided on one side of the upper surface of the base plate 1, and a roller 21 is provided on the other side of the upper surface of the base plate 1 to reduce rolling friction.

[0035] By checking the scale 20, the length of the aerated block extending out of the lower cutter 5 can be determined, making it convenient to cut the corresponding size as needed. When the aerated block is pushed to the side of the lower cutter 5, the roller 21 can reduce the friction between the aerated block and the base plate 1.

[0036] In this embodiment, as a preferred option, the upper surface of the lifting plate 4 is provided with a trapezoidal groove 22 along the length direction, and the lower cutter 5 is detachably disposed on the inner wall of the trapezoidal groove 22.

[0037] The lower cutter 5 is detachably connected to the lifting plate 4, allowing for easy replacement of the lower cutter 5 after prolonged use. By setting the trapezoidal groove 22, the stability of the lower cutter 5 and the lifting plate 4 can be improved while facilitating replacement, reducing the shaking of the lower cutter 5 during the cutting process.

[0038] In this invention, the working steps of the device are as follows:

[0039] 1. Place the aerated concrete block on the base plate 1, rotate the adjusting rod 16 to adjust the direction of the clamping plate 18 to the vertical position of the cutter, push the aerated concrete block to the side of the cutter, and check the measuring ruler on the base plate 1 to determine the cutting position.

[0040] 2. After determining the position, rotate the threaded rod 13 to lower the lifting plate 14, so that the upper cutter 15 at the bottom of the lifting plate 14 presses against the top of the air block. Rotate the drive rod 9 so that the lower cutter 5 cuts the air block. After the cutting is completed, reverse the drive rod 9 and move the lifting plate 14 upward to continue cutting at the position of the air block on the adjustment frame.

[0041] 3. After prolonged use, replace the lower cutter 5 on the lifting plate 4 to maintain brick cutting efficiency.

[0042] The specific embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
