[0020] Please see Figures 1-5A multi-angle cutting device for dry blanks of autoclaved aerated concrete (AAC) slabs includes a worktable 1, a first angle adjustment unit, a fixed cutting unit, and a sliding cutting unit. The lower surface of the worktable 1 is fixed to a welded base 2, which increases the contact area and improves overall stability, preventing cutting wobbling from affecting accuracy. A CNC unit 20 is fixed to the right side of the upper surface of the worktable 1. Its internal control module is connected via wires to a first motor 4, a second motor 12, a third motor 14, a first electric slide rail 6, a second electric slide rail 16, a third electric slide rail 18, and the driving components of each cutting saw, forming a centralized control link to achieve fully parameterized operation. Fixed cutting and first angle adjustment unit: The first support frame 3 of the first angle adjustment unit is fixed to the left side of the worktable 1. The first motor 4 is fixed to the inner bottom wall of the first support frame 3. The output shaft of the first motor 4 is connected to the first turntable 5 through a flat key. The first turntable 5 and the inner side wall of the first support frame 3 are rotated together by bearings to ensure rotational stability. The rear end bolt of the first electric slide rail 6 of the fixed cutting unit is fixed to the first turntable 5. The first cutting saw 7 is fixed to the lower surface of the slider of the first electric slide rail 6, which can realize 0-90° angle adjustment and cutting action. Sliding cutting and second angle adjustment unit: A sliding groove 8 is opened on the rear side of the worktable 1, and the sliding groove 8 is slidably connected to the sliding platform 9; a hinge block 11 is fixedly connected to the lower surface of the sliding platform 9, and a second motor 12 is installed on the lower surface of the worktable 1. The output shaft of the second motor 12 is fixed to a lead screw 13 through a coupling. The lead screw 13 is threadedly driven with the inner wall of the hinge block 11, forming a sliding drive system of "second motor 12-lead screw 13-hinge block 11-sliding platform 9". The second support frame 10 of the second angle adjustment unit is bolted to the sliding platform 9. A third motor 14 is fixedly connected to the inner wall of the second support frame 10. The output shaft of the third motor 14 is connected to a second turntable 15, and the second turntable 15 is rotatably engaged with the bearing on the inner wall of the second support frame 10. The sliding cutting unit includes a longitudinal cutting unit and a transverse cutting unit: the rear end of the second electric slide rail 16 of the longitudinal cutting unit is fixed to the second turntable 15, and the lower surface of the slider of the second electric slide rail 16 is fixed to the second cutting saw 17; the left end of the third electric slide rail 18 of the transverse cutting unit is fixed to the second turntable 15, and the third electric slide rail 18 and the second electric slide rail 16 are set at right angles, and the lower surface of the slider of the third electric slide rail 18 is fixed to the third cutting saw 19, thus forming a sliding cutting structure that can be angled and switched.

[0021] Specifically, the operator places the dry aerated concrete (AAC) slab blank on workbench 1 and inputs the length cutting parameters through the CNC unit 20. The CNC unit 20 first controls the second motor 12 to start, driving the lead screw 13 to rotate. Through threaded transmission, the sliding platform 9 slides along the slide groove 8, moving the second cutting saw 17 to the preset position. Simultaneously, it controls the first electric slide rail 6 to drive the first cutting saw 7 into position. Then, the first cutting saw 7 and the second cutting saw 17 are started synchronously, and the sliders of the first and second electric slide rails 6 and 16 are controlled to move at a uniform speed, achieving synchronous cutting along the length of the dry blank. This process requires no equipment replacement, saving floor space and reducing equipment costs compared to traditional multi-equipment operations. After length cutting is completed, if width cutting is required, the operator inputs the width parameters and issues a cross-cutting command through the CNC unit 20. The CNC unit 20 controls the third motor 14 to start, driving the second turntable 15 to rotate 90° clockwise, making the third electric slide rail 18 parallel to the width direction of the blank, and then the third motor 14 is locked. Next, the second motor 12 is controlled to drive the sliding platform 9 to move, moving the third cutting saw 19 to the width cutting starting position; the third cutting saw 19 is started, and the slider of the third electric slide rail 18 is controlled to move at a constant speed to complete the width cutting. The function of switching from longitudinal cutting to cross-cutting is achieved by adjusting the second turntable 15, without the need for additional equipment, saving time compared with traditional equipment switching, and the cutting accuracy error is smaller. When cutting autoclaved aerated concrete (AAC) slabs with beveled ends, the operator inputs the bevel angle parameters via the CNC unit 20. The CNC unit 20 then controls the start of the first motor 4 and the third motor 14 (note that both motors 4 and 14 are servo motors, supporting precise adjustment of any angle from 0-90°), driving the first turntable 5 and the second turntable 15 to rotate to the preset bevel angle. This aligns the first cutting saw 7 and the second cutting saw 17 with the bevel cutting paths at both ends of the blank, and then the first motor 4 and the third motor 14 are locked. The blank is placed on the worktable 1, and its position is adjusted via the CNC unit 20. Simultaneously, the first cutting saw 7 and the second cutting saw 17 are started, controlling the sliders of the first electric slide rail 6 and the second electric slide rail 16 to move at a uniform speed, completing the synchronous bevel cutting at both ends. During the process, the CNC unit 20 monitors the angles of the first motor 4 and the third motor 14 and the speeds of the first cutting saw 7 and the second cutting saw 17 in real time, significantly improving efficiency compared to traditional manual bevel cutting.

[0022] In summary, when using the overall equipment: In practical applications, the multi-functional CNC cutting saw for autoclaved aerated concrete (AAC) panels of this invention is first installed in a suitable production site. Based on the dimensions of the dry AAC panel blank to be processed, the operator sets the required panel length parameters through the CNC unit 20. The CNC unit 20 controls the second motor 12 to work, driving the sliding platform 9 to move along the slide groove 8, causing the second cutting saw 17 on the second electric slide rail 16 and the first cutting saw 7 on the first electric slide rail 6 to move to the corresponding positions. Then, the first cutting saw 7 and the second cutting saw 17 work simultaneously to complete the cutting of the dry AAC panel blank along its length. If cross-cutting of the product is required, a command is issued in the CNC unit 20 to control the third motor 14 to drive... The second turntable 15 rotates 90 degrees, putting the third cutting saw 19 into the working position. Then, the sliding platform 9 is controlled to move, driving the third cutting saw 19 to cut the dry blank of the autoclaved aerated concrete board in the width direction. When it is necessary to cut the board with beveled ends, the required bevel angle parameters are set in the CNC unit 20. The second support frame 10 controls the first turntable 5 and the second turntable 15 to rotate at the corresponding angle according to the parameters, so that the first electric slide rail 6 and the first cutting saw 7 on the first turntable 5 and the second turntable 15, as well as the second electric slide rail 16 and the second cutting saw 17, are at a suitable tilt angle. Then, the beveled cutting operation is performed. Throughout the cutting process, the CNC unit 20 monitors the operating status of each component in real time to ensure cutting accuracy and equipment operation stability.
