Description

Technical Field

[0001] The present invention relates to the field of cutting equipment, and particularly to a cutting equipment for precast composite wall panels. Background Art

[0002] Precast composite wall panels have been widely used in the modern construction field due to their advantages such as rapid construction, stable performance, and environmental friendliness. Such wall panels are usually composed of a combination of various materials, such as concrete, thermal insulation materials, decorative surfaces, etc., to meet different building requirements and standards. Existing wall panel cutting technologies mostly rely on traditional mechanical cutting methods, such as circular saw cutting or water jet cutting. Although these methods are effective in some cases, during the cutting process, due to the continuous friction between the cutting device and the composite wall panel, and the manual restraining force on the panel may not be stable enough, vibrations will occur, reducing the stability of the cutting work. To solve the above problems, after retrieval, a precast composite wall panel cutting device with the publication number CN222245462U is disclosed. It is proposed in the document that the staff transports the composite wall panel to the tabletop of the workbench through a handling device, turns the handle of the second screw, and the second screw drives the side plate to move through the second rotating block and the second circular shell under the threaded support of the top cover... The staff pushes the composite wall panel to make the cutting wheel contact the composite wall panel for cutting work. Although the above device can cut precast composite wall panels, in actual use, it is necessary for the staff to transport the composite wall panel to the workbench through a handling device. The precast composite wall panel is manually pushed for cutting. Usually, the precast composite wall panel is heavy. When manually pushing, if the center of gravity of the wall panel is unstable or it suddenly slides, it may cause the operator to be squeezed or collided by the wall panel, resulting in physical injuries. Manually pushing the composite wall panel for cutting is difficult to ensure the uniformity and stability of the pushing speed, which will cause the cutting line to be not straight or flat, and the cutting size error is large, affecting the installation and use effect of the precast composite wall panel.

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in the figure, Specific Embodiment 5: This embodiment is a further limitation of Specific Embodiment 2. A handle 216 is fixedly arranged on the top of the machine base 212, and a rubber gasket is fixedly arranged on the handle 216. At the same time, three limiting through holes are evenly formed in the limiting seat 214 at the bottom of the machine base 212; Limiting posts 215 are inserted into the interiors of the three limiting through holes, and the ends of the three limiting posts 215 are fixedly arranged on the inner wall of the cutting track 1; The cutting track 1 covers the composite wallboard and cutting is performed by the cutting disc 22 moving horizontally along the limiting posts 215.

[0029] As Figure 1 and Figure 5 As shown in the figure, Specific Embodiment 6: This embodiment is a further limitation of Specific Embodiment 1. The first clamping mechanism 3 and the second clamping mechanism 4 have the same composition structure. The second clamping mechanism 4 includes a clamping plate 41, an adjusting seat 42, an adjusting groove 43, an insertion opening 44, a connecting piece 45, a nut 46 and a stud 47. Two adjusting grooves 43 are formed at both ends of the cutting track 1, and adjusting seats 42 are inserted into the interiors of the two adjusting grooves 43. Clamping plates 41 are fixedly connected to the ends of the two adjusting seats 42 by screwing; The clamping plate 41 and the adjusting seat 42 are perpendicular to each other. The height of the clamping plate 41 is greater than the thickness of the cutting track 1, and a rubber pad is adhesively fixed to the inner wall surface of the clamping plate 41; The cutting track 1 covers the surface of the composite wallboard and is clamped and fixed by the first clamping mechanism 3 and the second clamping mechanism 4.

[0030] Working principle: When in actual use, first cover the cutting track 1 on the composite wallboard. At this time, the cutting track 1 covers the surface of the composite wallboard and is clamped on the workbench by the first clamping mechanism 3 and the second clamping mechanism 4. The composite wallboard to be cut is placed on the workbench, and the cutting length of the composite wallboard is less than the length of the cutting track 1; ensure the stability of the cutting mechanism 2 during operation, so that it will not loosen, so that when the cutting blade 22 on the cutting mechanism 2 moves, it will not tilt, ensuring the flatness of the cut surface of the composite wallboard; hold the handle 216 on the hand-held base 212, move the drive motor 213 horizontally on the cutting track 1 and move horizontally along the limit post 215, and cut the composite wallboard through the cutting blade 22; the output shaft of the drive motor 213 rotates at a high speed, which can drive the cutting blade 22 to rotate at a high speed to complete the cutting work on the composite wallboard; there is no need to cover the composite wallboard on the workbench, and the composite wallboard can be cut by pushing it by hand, which is simpler and faster during cutting; the cutting track 1 provides an accurate running track for the cutting blade 22, which can ensure that the cutting blade 22 moves along the predetermined route, avoiding situations such as running off track or skewing during cutting, so as to ensure that the cut surface of the composite wallboard is flat and the size is accurate, which is very important for construction or furniture manufacturing scenarios with high-precision requirements; compared with manually holding a cutting tool for cutting, the cutting track 1 can effectively reduce the cutting errors caused by human factors such as the technical level of the operator and hand tremors, making the cutting quality more stable and reliable; due to the cutting track 1 and the two groups of clamping mechanisms ensuring the stability of the cutting process, the cutting blade 22 can be evenly stressed when cutting the composite wallboard, and there will be no situations of uneven depth or unevenness. The surface of the cut composite wallboard is smooth and flat, and there is no need for excessive subsequent grinding treatment, and it can directly enter the next construction process, improving work efficiency and reducing costs at the same time; the stable cutting process can make the contact between the cutting blade 22 and the composite wallboard more uniform, reducing material tearing, chipping and other damages caused by uneven cutting force, thereby improving the yield rate of the composite wallboard and reducing material waste; the cutting track 1 restricts the movement range of the cutting blade 22 to prevent the cutting blade 22 from accidentally deviating from the predetermined track during cutting, causing harm to the operator or the surrounding environment, and reducing safety risks; the first clamping mechanism 3 and the second clamping mechanism 4 firmly clamp the composite wallboard, which not only ensures the stability of cutting, but also prevents the composite wallboard from moving or bouncing during cutting, further improving the safety of operation, enabling the operator to focus more on the cutting work and reducing operation errors caused by worrying about safety issues; the stable action of the cutting track 1 and the clamping mechanism enables the cutting blade 22 to continuously and stably carry out the cutting work, reducing the number of times of suspension and adjustment due to unstable cutting, improving the cutting speed and efficiency, and being able to complete the cutting task of a large number of composite wallboards in a short time to meet the project progress requirements;No complex operating skills and experience are required, reducing the labor intensity of operators and shortening the training time, enabling more people to quickly get started with cutting operations.

[0031] As Figure 5 shown, Specific Embodiment 7: This embodiment is a further limitation of Specific Embodiment 6. Insertion openings 44 are provided at the tops of the two sets of adjustment slots 43. At the same time, two sets of stud bolts 47 are inserted into the insertion openings 44. The bottoms of the two sets of stud bolts 47 are fixedly arranged on the end surfaces of the adjustment seats 42. Connecting pieces 45 are sleeved on the two sets of stud bolts 47, and nuts 46 are screwed and installed on the outer sides of the stud bolts 47.

[0032] The distance between the first clamping mechanism 3 and the second clamping mechanism 4 can be adjusted to adapt to cutting workbenches of different widths.

[0033] As Figure 5 、 Figure 7 and Figure 8 shown, Specific Embodiment 8: This embodiment is a further limitation of Specific Embodiment 2. The cutting blade 22 includes a saw blade 221, an opening 222, a positioning frame 223, and a central piece 224. Three groups of saw blades 221 are evenly arranged along the circumferential outer wall of the central piece 224, and the three groups of saw blades 221 are centrosymmetric structures along the circumferential outer wall of the central piece 224.

[0034] As Figure 5 、 Figure 7 and Figure 8 shown, Specific Embodiment 9: This embodiment is a further limitation of Specific Embodiment 8. Positioning frames 223 are provided on the three groups of saw blades 221. The cross-section of the positioning frame 223 is set in a "U" shape. The three groups of saw blades 221 are clamped on the outer side of the central piece 224 through the positioning frames 223 at the ends and are connected by multiple sets of fixing bolts.

[0035] As Figure 5 、 Figure 7 and Figure 8 shown, Specific Embodiment 10: This embodiment is a further limitation of Specific Embodiment 8. Openings 222 are provided on the three groups of saw blades 221. The openings 222 are arc-shaped. The saw blades 221 are fan-shaped structures made of metal materials; the central piece 224 is a circular structure made of metal materials, and a detachable structure exists between the central piece 224 and the three groups of saw blades 221 arranged on its outer side.

[0036] The cutting disc 22 includes a saw blade 221, an opening 222, a positioning frame 223, and a center piece 224. Three groups of saw blades 221 are evenly arranged along the center piece 224. Compared with the integral cutting disc 22, when a certain group of sector-shaped saw blades 221 is damaged, only this small part needs to be replaced, instead of purchasing and replacing the entire circular cutting disc 22, which reduces the procurement cost of the cutting disc 22. Especially for the cutting disc 22 with a relatively high price, this cost saving is more significant; it shortens the equipment maintenance time, resumes the cutting work as soon as possible, improves the production efficiency, and reduces the indirect cost loss caused by equipment downtime; the operation of replacing a single sector-shaped saw blade 221 is relatively simple, without the need for complex disassembly and installation tools and techniques, reducing the work difficulty and labor intensity of the operator, and also shortening the time required to replace the saw blade 221; only a small number of sector-shaped saw blades 221 need to be stocked as spare parts, instead of requiring a large inventory of complete saw blades of different specifications like the integral saw blade, saving the inventory space and also reducing the difficulty and cost of inventory management.

[0037] The present invention covers any alternatives, modifications, equivalent methods, and solutions made within the spirit and scope of the present invention.

However, those skilled in the art can fully understand the present invention without these detailed descriptions. Additionally, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
