[0002] In the field of building materials production, steam-pressurized concrete blocks have been widely used due to their excellent properties such as lightweight, heat insulation, and sound insulation. In the production process of steam-pressurized concrete blocks, the cutting process is a crucial step that determines the dimensional accuracy and quality of the blocks.

[0003] In practical applications, aerated concrete blocks often need to be cut into various specific sizes to meet the needs of different building scenarios, including irregular shapes. However, current cutting devices on the market exhibit significant shortcomings when dealing with cutting irregularly shaped blocks. The cutting methods are extremely rudimentary, mostly relying on pre-drawing lines on the block surface or on the operator's experience for rough cutting. This method not only consumes a lot of time and extends the production cycle but also makes it difficult to ensure cutting accuracy, resulting in large dimensional deviations in the cut blocks. This fails to meet the stringent requirements of building construction, leading to material waste and increased costs. Summary of the Invention

[0027] like Figure 1-4 As shown, a steam-pressurized concrete block cutting device includes:

[0028] Lifting mechanism 100:

[0029] Support plate 101: As the basic support component of the entire device, it supports other structural components and ensures the stability of the device during operation. During the cutting process, it provides a stable support platform for components such as hydraulic cylinder 104, enabling hydraulic cylinder 104 to smoothly push the crossbeam 103 up and down.

[0030] Support rods 102: Two symmetrically arranged on the support plate 101 provide guidance for the crossbeam 103, enabling the crossbeam 103 to rise and fall stably along the direction of the support rods 102, ensuring the accuracy of the cutting height adjustment. The crossbeam 103 forms a sliding pair with the support rods 102 through the sliding sleeves 105 at both ends. Driven by the hydraulic cylinder 104, it moves linearly along the support rods 102, thereby achieving precise adjustment of the cutting height.

[0031] Crossbeam 103: Slidably sleeved on support rod 102, and fixedly connected to the output end of hydraulic cylinder 104, it achieves lifting and lowering movement under the drive of hydraulic cylinder 104, thereby driving the cutting mechanism 200 to adjust its height to meet the needs of cutting blocks of different heights. At the same time, drive components and cutting parts are installed on crossbeam 103, providing support for the movement of cutting parts and cutting operations.

[0032] Hydraulic cylinders 104 are symmetrically arranged on both sides of the support plate 101, with their output ends rigidly connected to the crossbeam 103. They provide power for the lifting and lowering of the crossbeam 103, enabling precise control of its lifting height and ensuring the accuracy of the cutting height. During the cutting process, the hydraulic cylinders 104 push the crossbeam 103 downward, causing the cutting wire 205 to contact the block for cutting. After cutting, the hydraulic cylinders 104 drive the crossbeam 103 upward, causing the cutting wire 205 to detach from the block.

[0033] Cutting mechanism 200:

[0034] Driver components:

[0035] Rotary motor 201: Mounted on the crossbeam 103, serving as a power source, it not only drives the cutting workpiece to move on the crossbeam 103 but also plays a crucial role in adjusting the angle of the cutting wire 205. The output end of the rotary motor 201 extends into the groove 211 at the top of the crossbeam 103 and is connected to the screw 202 via a bevel gear set, transmitting the rotational motion to the screw 202.

[0036] Screw 202: Rotatably mounted inside the groove 211 at the top of the crossbeam 103, and driven by a bevel gear set to the output end of the rotary motor 201. Screw 202 is threadedly connected to any slider 207, converting the rotational motion of the rotary motor 201 into the linear motion of the slider 207, thereby driving the cutting part to move on the crossbeam 103, realizing the cutting of the block and the adjustment of the angle of the cutting wire 205.

[0037] Spacing adjustment component:

[0038] Scissor lift 203: Mounted on slider 207, scissor lifts 203 on adjacent sliders 207 on the same side are rotatably connected by a pin. Scissor lift 203 includes a connecting shaft fixedly mounted on slider 207 and two rotating rods intersectingly mounted on the connecting shaft. When adjusting the distance between adjacent sliders 207, scissor lift 203 can simultaneously adjust the spacing of adjacent cutting wires 205 by extending or retracting itself, to meet the cutting requirements of blocks of different sizes.

[0039] Fixing screw 204: Threaded connection to slider 207, with one end abutting against crossbeam 103. By tightening or loosening fixing screw 204, the position of slider 207 on crossbeam 103 can be fixed or adjusted, thereby achieving precise control of the spacing of cutting wires 205.

[0040] Cutting parts:

[0041] Cutting wire 205: As a component that directly cuts the blocks, it achieves the cutting operation through friction with the blocks. During the cutting process, the angle and spacing of the cutting wire 205 can be adjusted according to the shape and size of the blocks to improve cutting accuracy and adaptability.

[0042] Cutting wheel 206: Located at both ends of the cutting wire 205, with the ends of the cutting wire 205 wound around the cutting wheel 206. The cutting wheel 206 is rotatably mounted on the fixing bolt 209. During the cutting process, the cutting wheel 206 rotates as the cutting wire 205 moves, reducing the friction between the cutting wire 205 and the block, improving cutting efficiency and extending the service life of the cutting wire 205.

[0043] Slider 207: Fixedly connected to the cutting wheel 206, it is slidably sleeved on the crossbeam 103. Under the action of the drive assembly, it drives the cutting wire 205 and the cutting wheel 206 to move on the crossbeam 103. Simultaneously, a spacing adjustment assembly is installed on slider 207 to adjust the spacing between adjacent cutting wires 205. When the angle of the cutting wire 205 is adjusted, the horizontal position of slider 207 changes, thereby achieving the adjustment of the angle of the cutting wire 205.

[0044] Support 208: Fixedly connected to slider 207, used to install fixing bolts 209, and provides support for the rotation of cutting wheel 206. Support 208 ensures the stability of cutting wheel 206 and cutting wire 205, enabling the cutting operation to proceed smoothly.

[0045] Fixing bolt 209: Fixedly installed on bracket 208, the cutting wheel 206 is rotatably sleeved on fixing bolt 209, and fixing nut 210 is provided on fixing bolt 209 to fix the winding length of cutting wire 205 and ensure the stability of cutting wire 205 during operation. When adjusting the angle of cutting wire 205, it is necessary to loosen fixing nut 210, and then tighten it after adjustment to ensure that cutting wire 205 is in a taut state.

[0046] Working principle:

[0047] Spacing Adjustment: Based on the size requirements of the block to be cut, the operator tightens the fixing screw 204. The fixing screw 204 is threadedly connected to the slider 207. When the fixing screw 204 is loosened, the slider 207 can slide relative to each other on the crossbeam 103. The scissor arms 203 on two adjacent sliders 207 on the same side are rotatably connected by a pin. The scissor arms 203 consists of a connecting shaft fixed on the slider 207 and two rotating rods crossed on the connecting shaft. As the slider 207 slides, the scissor arms 203 extend or retract, thereby synchronously adjusting the spacing between adjacent cutting wires 205 to meet the cutting requirements of blocks of different sizes.

[0048] Angle adjustment:

[0049] Loosen the fixing nut 210 and start the rotary motor 201. The rotary motor 201 is mounted on the crossbeam 103, and its output end extends into the groove 211 at the top of the crossbeam 103, and is connected to the screw 202 via a bevel gear set. The rotary motor 201 operates, driving the output shaft to rotate, and transmitting the rotational motion to the screw 202 via the bevel gear set, causing the screw 202 to rotate within the groove 211. Since the screw 202 is threadedly connected to any slider 207, the rotation of the screw 202 is converted into linear motion of the slider 207 on the crossbeam 103. The slider 207 is fixedly connected to the cutting wheel 206 via the bracket 208, thereby driving the cutting piece composed of the cutting wire 205 and the cutting wheel 206 to move along the crossbeam 103, thereby changing the horizontal position of the two sliders 207 of the cutting wire 205, thus achieving angle adjustment of the cutting wire 205 to meet the cutting requirements of blocks of different shapes. Then, tighten the fixing nut 210 again to ensure that the cutting wire 205 is in a taut state.

[0050] Cutting process

[0051] Hydraulic cylinders 104 are activated. These cylinders are symmetrically distributed on both sides of the support plate 101, with their output ends rigidly connected to the crossbeam 103. When hydraulic cylinders 104 operate, their output ends move downwards, pushing the crossbeam 103 to slide downwards along the support rod 102. The sliding sleeves 105 at both ends of the crossbeam 103 and the support rod 102 form a sliding pair, ensuring smooth lifting and lowering of the crossbeam 103. The cutting wire 205, as a component that directly cuts the blocks, contacts the blocks during the descent of the crossbeam 103, cutting the blocks.

[0052] After cutting, the hydraulic cylinder 104 lifts the crossbeam 103, causing the cutting wire 205 to detach from the block, thus completing the entire cutting operation. If new blocks need to be cut subsequently, the above-mentioned spacing adjustment, angle adjustment, and cutting operations are repeated according to the size and shape requirements of the new blocks.
