Description

Technical Field

[0001] The present invention relates to the field of cutting equipment, in particular to a cutting equipment for prefabricated composite wall panels. Background Art

[0002] Prefabricated composite wall panels are widely used in modern construction due to their rapid construction, stable performance, and environmental friendliness. These panels are typically composed of a variety of materials, such as concrete, insulation, and decorative finishes, to meet diverse building requirements and standards. Existing wall panel cutting techniques often rely on traditional mechanical cutting methods, such as circular saws or water jets. While these methods are effective in some cases, they can cause vibrations during the cutting process due to the constant friction between the cutting device and the composite wall panel, and the manual restraining force on the panel can be unstable, reducing cutting stability.

[0003] To address the above-mentioned issues, a search revealed a prefabricated composite wall panel cutting device with publication number CN222245462U. The device proposes that a worker transports the composite wall panel to a workbench surface using a transport device. The worker then rotates the handle of a second screw, which, supported by the threads of the top cover, drives the side panels through a second rotating block and a second circular shell. The worker then pushes the composite wall panel, causing the cutting wheel to contact the composite wall panel and cut the composite wall panel.

[0004] Although the above-mentioned device can cut prefabricated composite wall panels, in actual use, the composite wall panels need to be manually transported to the workbench through the transport device; the composite wall panels are manually pushed for cutting, and the prefabricated composite wall panels are usually heavy. When manually pushed, if the center of gravity of the wall panels is unstable or suddenly slides, the operator may be squeezed or collided with the wall panels, causing physical injury. Manually pushing the composite wall panels for cutting makes it difficult to ensure the uniformity and stability of the pushing speed, which will cause the cutting lines to be non-straight and uneven, and the cutting size error is large, affecting the installation and use of the prefabricated composite wall panels. Summary of the Invention

[0005] The object of the present invention is to provide a cutting device for prefabricated composite wall panels to solve the defects mentioned in the above background technology.

[0009] Furthermore, the bottoms of the two sets of metal hoses are fixedly connected with nozzles, the tops of the metal hoses are fixedly provided with connecting pipes, the connecting pipes are "U" shaped, and a cooling water boosting pipe is fixedly provided in the middle of the connecting pipes.

[0010] Furthermore, a handle is fixedly provided on the top of the machine base, and a rubber pad is fixedly provided on the handle. At the same time, three groups of limit holes are evenly opened on the limit seat at the bottom of the machine base; the interiors of the three groups of limit holes are interspersed with limit columns, and the ends of the three groups of limit columns are fixedly provided on the inner wall of the cutting track; the cutting track is covered on the composite wall panel and the cutting work is performed by a cutting blade that moves laterally along the limit columns.

[0011] Furthermore, the first clamping mechanism and the second clamping mechanism have the same composition structure. The second clamping mechanism includes a clamping plate, an adjustment seat, an adjustment groove, an insertion port, a connecting piece, a nut and a stud. Two sets of adjustment grooves are provided at both ends of the cutting track. Adjustment seats are inserted into the interiors of the two sets of adjustment grooves. The ends of the two sets of adjustment seats are screwed and fixed with clamps; the clamping plate and the adjustment seat are vertically arranged, the height of the clamping plate is greater than the thickness of the cutting track, and a rubber pad is bonded and fixed to the inner wall surface of the clamping plate; the cutting track is covered on the surface of the composite wall panel and is clamped and fixed by the first clamping mechanism and the second clamping mechanism.

[0012] Furthermore, the tops of the two sets of adjustment slots are provided with insertion openings, and two sets of studs are inserted into the inside of the insertion openings. The bottoms of the two sets of studs are fixedly set on the end surface of the adjustment seat, and connecting plates are sleeved on the two sets of studs. Nuts are screwed on the outer sides of the studs.

[0013] Furthermore, the cutting blade includes a saw blade, an opening, a positioning frame and a center piece. The saw blades are evenly arranged in three groups along the circumferential outer wall of the center piece.

[0017] 1. The present invention covers the surface of the composite wall panel with a cutting track and clamps and fixes it through a first clamping mechanism and a second clamping mechanism, thereby ensuring the stability of the cutting mechanism during operation and preventing it from loosening. By holding the handle on the machine base, the drive motor moves laterally on the cutting track and along the limit column, and the composite wall panel is cut by the cutting blade. The cutting track provides a precise running track for the cutting blade, ensuring that the cutting blade moves along the predetermined route, avoiding deviation or skew during the cutting process, thereby ensuring that the cut surface of the composite wall panel is flat and the size is accurate. The surface of the composite wall panel after cutting is smooth and flat, and no excessive subsequent polishing is required, and it can directly enter the next construction process.

[0018] 2. The present invention evenly arranges three groups of saw blades along the center piece. Compared with the integral cutting blade, when a group of fan-shaped saw blades is damaged, only this small part needs to be replaced instead of purchasing and replacing the entire circular cutting blade, thereby reducing the procurement cost of the cutting blade. Especially for the higher-priced cutting blades, this cost saving is more significant; shortening the equipment maintenance time, and resuming cutting work as soon as possible.

[0040] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, specific embodiment five: This embodiment is a further limitation of specific embodiment two, a handle 216 is fixedly provided on the top of the machine base 212, and a rubber pad is fixedly provided on the handle 216. At the same time, three groups of limiting perforations are evenly opened on the limiting seat 214 at the bottom of the machine base 212; limiting columns 215 are inserted into the interior of the three groups of limiting perforations, and the ends of the three groups of limiting columns 215 are fixedly provided on the inner wall of the cutting track 1; the cutting track 1 is covered on the composite wall panel and performs cutting work by the cutting blade 22 that moves laterally along the limiting columns 215.

[0041] like Figure 1 and Figure 5 As shown, specific embodiment six: This embodiment is a further limitation of specific embodiment one, and the composition structure of the first clamping mechanism 3 and the second clamping mechanism 4 is consistent. The second clamping mechanism 4 includes a clamping plate 41, an adjustment seat 42, an adjustment groove 43, an insertion port 44, a connecting piece 45, a nut 46 and a stud 47. Two groups of adjustment grooves 43 are provided at both ends of the cutting track 1. The interiors of the two groups of adjustment grooves 43 are interspersed with adjustment seats 42, and the ends of the two groups of adjustment seats 42 are screwed and fixed with clamps 41; the clamping plate 41 and the adjustment seat 42 are vertically arranged, the height of the clamping plate 41 is greater than the thickness of the cutting track 1, and a rubber pad is bonded and fixed to the inner wall surface of the clamping plate 41; the cutting track 1 is covered on the surface of the composite wall panel and is clamped and fixed by the first clamping mechanism 3 and the second clamping mechanism 4.

[0042] Working principle: When actually using, first cover the cutting track 1 on the composite wall panel. At this time, the cutting track 1 covers the surface of the composite wall panel and is clamped on the workbench by the first clamping mechanism 3 and the second clamping mechanism 4. The composite wall panel to be cut is placed on the workbench. The cutting length of the composite wall panel should be less than the length of the cutting track 1. Ensure the stability of the cutting mechanism 2 during operation and it will not loosen, so that the cutting blade 22 on the cutting mechanism 2 will not tilt when moving, ensuring the flatness of the cross section of the composite wall panel. Hold the handle 216 on the machine base 212 to drive the motor 213 to move horizontally on the cutting track 1 and move horizontally along the limit column 215. Through the cutting blade 22 The composite wall panel is cut; the output shaft of the driving motor 213 rotates at high speed, which can drive the cutting blade 22 to rotate at high speed to complete the cutting of the composite wall panel; there is no need to cover the composite wall panel on the workbench, and the composite wall panel can be cut by pushing it by hand, which is simpler and faster when cutting; the cutting track 1 provides a precise running track for the cutting blade 22, which can ensure that the cutting blade 22 moves along the predetermined route, avoiding deviation, skewness, etc. during the cutting process, thereby ensuring that the cutting surface of the composite wall panel is flat and the size is accurate, which is very important for scenes such as construction or furniture manufacturing with high precision requirements; compared with manual cutting with hand-held cutting tools, the cutting track 1 can effectively reduce the technical level of the operator , hand shaking and other human factors, making the cutting quality more stable and reliable; because the cutting track 1 and the two sets of clamping mechanisms ensure the stability of the cutting process, the cutting blade 22 can be evenly stressed when cutting the composite wallboard, and there will be no unevenness or unevenness. The surface of the composite wallboard after cutting is smooth and flat, and no excessive subsequent grinding is required. It can directly enter the next construction process, thereby improving work efficiency and reducing costs; the stable cutting process can make the contact between the cutting blade 22 and the composite wallboard more uniform, reducing damage such as material tearing and edge collapse caused by uneven cutting force, thereby improving the yield of the composite wallboard and reducing material waste; the cutting track 1 limits the movement range of the cutting blade 22 to prevent The cutting blade 22 may accidentally deviate from the predetermined trajectory during the cutting process, thereby preventing harm to the operator or the surrounding environment, thereby reducing safety risks. The first clamping mechanism 3 and the second clamping mechanism 4 firmly clamp the composite wall panel, which not only ensures cutting stability but also prevents the composite wall panel from moving or bouncing during the cutting process, further improving operational safety and allowing the operator to focus more on the cutting work, thereby reducing operational errors caused by concerns about safety issues. The stabilizing effect of the cutting track 1 and the clamping mechanism enables the cutting blade 22 to perform cutting work continuously and stably, reducing the number of pauses and adjustments required due to unstable cutting, improving cutting speed and efficiency, and completing the cutting task of a large number of composite wall panels in a relatively short time, thereby meeting project schedule requirements.It does not require complicated operating skills and experience, which reduces the labor intensity of operators and shortens training time, allowing more people to quickly get started with cutting operations.

[0043] like Figure 5 As shown, specific embodiment seven: This embodiment is a further limitation of specific embodiment six, and the tops of the two groups of adjustment grooves 43 are each provided with an insertion opening 44, and two groups of studs 47 are inserted into the inside of the insertion opening 44, and the bottoms of the two groups of studs 47 are fixedly set on the end surface of the adjustment seat 42, and the two groups of studs 47 are both sleeved with connecting pieces 45, and the outer sides of the studs 47 are threadedly installed with nuts 46.

[0044] 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.

[0045] like Figure 5 、 Figure 7 and Figure 8 As shown, specific embodiment eight: This embodiment is a further limitation of specific embodiment two, the cutting blade 22 includes a saw blade 221, an opening 222, a positioning frame 223 and a center piece 224, and the saw blades 221 are evenly arranged in three groups along the circumferential outer wall of the center piece 224, and the three groups of saw blades 221 are a centrally symmetrical structure along the circumferential outer wall of the center piece 224.

[0046] like Figure 5 、 Figure 7 and Figure 8 As shown, specific embodiment nine: This embodiment is a further limitation of specific embodiment eight. A positioning frame 223 is provided on each of the three groups of saw blades 221. The cross-section of the positioning frame 223 is "U"-shaped. The three groups of saw blades 221 are clamped on the outer side of the center piece 224 through the positioning frame 223 at the end and are connected by multiple groups of fixing bolts.

[0047] like Figure 5 、 Figure 7 and Figure 8 As shown, specific embodiment ten: This embodiment is a further limitation of specific embodiment eight, and openings 222 are provided on the three groups of saw blades 221, and the openings 222 are arc-shaped. The saw blades 221 are fan-shaped structures made of metal material; the center piece 224 is a circular structure made of metal material, and the center piece 224 and the three groups of saw blades 221 arranged on its outside are detachable structures.

[0048] The cutting blade 22 includes a saw blade 221, an opening 222, a positioning frame 223 and a center piece 224. The saw blades 221 are evenly arranged in three groups along the center piece 224. Compared with the integral cutting blade 22, when a group of fan-shaped saw blades 221 is damaged, only this small part needs to be replaced, instead of purchasing and replacing the entire circular cutting blade 22, thereby reducing the procurement cost of the cutting blade 22. Especially for the higher-priced cutting blades 22, this cost saving is more significant; shortening the equipment maintenance time, resuming the cutting work as soon as possible, improving production efficiency, and reducing indirect cost losses caused by equipment downtime; the operation of replacing a single fan-shaped saw blade 221 is relatively simple, and does not require complicated disassembly and installation tools and techniques, reducing the operator's work difficulty and labor intensity, and shortening the time required to replace the saw blade 221; only a small number of fan-shaped saw blades 221 need to be stocked as spare parts, instead of requiring a large number of complete saw blades of different specifications as the integral saw blade, saving inventory space, and reducing the difficulty and cost of inventory management.
