Description

Technical Field

[0001] This utility model relates to the field of honeycomb aluminum panel processing technology, specifically to a mold for making curved honeycomb aluminum panels. Background Technology

[0002] Honeycomb aluminum panels are a series of metal composite panel products developed by combining composite honeycomb panel technology from the aerospace industry. This product adopts a "honeycomb sandwich" structure, that is, a composite panel made by bonding high-strength alloy aluminum plates with a decorative coating of excellent weather resistance as the face and back plates with an aluminum honeycomb core under high temperature and pressure. This product series has the advantages of excellent material selection, advanced technology, and reasonable structure. It not only exhibits excellent performance in large dimensions and flatness, but also offers numerous choices in shape, surface treatment, color, and installation systems. In addition to aluminum alloy, other materials can be selected for the panel according to customer needs, such as: copper, zinc, stainless steel, pure titanium, fireproof board, galvanized steel, marble, and aluminum composite panels.

[0003] In the manufacturing process of curved honeycomb aluminum panels, the mold is a crucial element, and currently, wooden templates are commonly used. Each wooden template can only process curved honeycomb aluminum panels of one type in curvature and shape, making them disposable. However, a large building may use thousands or even tens of thousands of curved honeycomb panels. Due to the different shapes and styles of curved metal roofs and curtain walls, the curvature and shape of each curved honeycomb aluminum panel are often not identical. Therefore, the processing efficiency and utilization rate of using wooden templates to manufacture curved honeycomb panels are very low, while the production cost is very high. Furthermore, it results in a significant waste of wood, which is detrimental to energy conservation and environmental protection. The existing technology suffers from the following problems:

[0004] In actual use, existing molds require the manufacture of a new upper and lower mold base each time they are used to process aluminum plates with different curvatures. This makes it impossible to achieve the purpose of recycling, greatly reducing processing and production efficiency, and easily causing material waste, which is not in line with the trend of energy conservation and environmental protection. At the same time, the upper mold base cannot be guided, and tilting may occur during the pressing of the aluminum plate, which will affect the surface forming effect and make it inconvenient to use.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides a mold for making curved honeycomb aluminum panels, including a frame 1. Two sets of hydraulic cylinders 2 are fixedly installed on the top of the frame 1. A mold mechanism 3 is installed on the upper and lower parts of the inner cavity of the frame 1. Positioning mechanisms 4 are symmetrically installed on both the left and right ends of the mold mechanism 3.

[0025] The output shaft of hydraulic cylinder 2 extends to the inside of frame 1.

[0026] The mold mechanism 3 allows the curved surfaces of the upper mold plate 33 and the lower mold plate 317 to be adjusted, eliminating the need to create new molds and enabling them to be reused, thus greatly improving processing and production efficiency. The positioning mechanism 4 guides the upper mold base 31, effectively preventing it from tilting, allowing the upper mold plate 33 to fit precisely with the lower mold plate 317, further enhancing the aluminum plate forming effect.

[0027] like Figure 1-5 As shown, the mold mechanism 3 includes an upper mold base 31, the upper end of which is fixedly connected to the output shaft of the hydraulic cylinder 2. Six sets of upper sliding rods 32 are slidably connected inside the upper mold base 31. An upper template 33 is fixedly installed at the lower end of the six sets of upper sliding rods 32. Multiple sets of positioning holes 24 are evenly distributed on the surface of the upper sliding rods 32. Positioning pins 35 are movably inserted into the interior of the positioning holes 24. A lower mold base 311 is fixedly installed at the bottom of the inner cavity of the frame 1. Six sets of handles 312 are movably installed on the front of the lower mold base 311. Locking pins 313 are movably inserted into the surface of the handles 312. A rotating rod 314 is fixedly installed at the rear end of the handles 312. A convex roller 315 is fixedly installed at the rear end of the rotating rod 314. Six sets of lower sliding rods 316 are slidably connected inside the lower mold base 311. A lower template 317 is fixedly installed at the upper end of the lower sliding rods 316.

[0028] The front surface of the lower mold base 311 is provided with six sets of locking holes at equal intervals. The locking pin 313 matches the locking hole and is movably connected. The rotating rod 314 and the convex roller 315 both extend into the interior of the lower mold base 311.

[0029] The lower end of the convex roller 315 is movably connected to the lower end of the sliding rod 316. The curvature of both the upper template 33 and the lower template 317 can be adjusted, with the upper template 33 located directly above the lower template 317.

[0030] like Figure 1-5 As shown, the positioning mechanism 4 includes a fixed base 41. One side of the fixed base 41 is symmetrically fixedly connected to both the left and right ends of the upper mold base 31. A sleeve rod 42 is fixedly installed at the lower end of the fixed base 41. A fixed plate 43 is fixedly installed on the outer end face of the lower end of the sleeve rod 42. A positioning rod 44 is slidably limited in the inner cavity of the sleeve rod 42. A spring 45 is sleeved on the outside of the positioning rod 44. A fixed base 46 is fixed at the bottom of the lower end of the positioning rod 44.

[0031] One end of the spring 45 is fixedly connected to the lower surface of the positioning plate, and the other end is fixedly connected to the upper surface of the fixed base 46.

[0032] One side of the fixed base 46 is symmetrically fixedly connected to both ends of the lower mold base 311.

[0033] The working principle of the mold for making curved honeycomb aluminum panels will be explained in detail below.

[0034] like Figure 1-5 As shown, when using the mold for making curved honeycomb aluminum panels, the curvature of the upper template 33 and the lower template 317 needs to be adjusted according to the processing requirements. A template with a curvature that meets the processing requirements can be selected, and the inner arc surface of the template is placed against the upper template 33. Then, the positioning pins 35 are removed from each upper sliding rod 32 in sequence, allowing the upper sliding rods 32 to slide freely up and down. Next, each upper sliding rod 32 is slid, and the curvature of each part of the upper template 33 is adjusted during the sliding process of each upper sliding rod 32 until the lower surface of the upper template 33 is completely aligned with the inner arc surface of the template. At this point, the curvature of the upper template 33 meets the processing requirements. Then, the positioning pins 35 are inserted into the positioning holes 24 of each upper slide rod 32 to lock the position of the upper slide rods 32, thereby locking the curvature of the upper template 33. Next, the lower template 317 is adjusted so that the outer arc surface of the template rests against the upper surface of the lower template 317. Then, the locking pin 313 on the handle 312 is removed, allowing the handle 312 to rotate freely. Rotating the handle 312 then drives the rotating rod 314 and the convex roller 315 to rotate synchronously. During the rotation of the convex roller 315... The different positions of the protrusions abut against the sliding rod 316, thereby realizing the sliding of the sliding rod 316. During the sliding process of each sliding rod 316, the curvature of each part of the lower template 317 is adjusted until the upper surface of the lower template 317 is completely in contact with the outer arc surface of the template. At this time, the curvature of the lower template 317 meets the processing requirements. Then, the locking pin 313 is inserted into the locking hole to lock the position of the sliding rod 316, thereby locking the curvature of the lower template 317. Then, the aluminum plate to be processed can be placed on the upper template 33, and then the hydraulic cylinder 2 is activated. Hydraulic cylinder 2 drives the upper mold base 31 and upper template 33 to move downward, so that the upper template 33 matches the lower template 317, thereby pressing the aluminum plate into a curved shape. At the same time, when the upper mold base 31 moves downward, the positioning rod 44 slides inside the sleeve rod 42 to guide the upper mold base 31, so that the upper template 33 can accurately contact the lower template 317. Meanwhile, under the action of the fixed plate 43, the spring 45 is compressed, and the spring 45 can buffer the upper mold base 31, effectively preventing the upper mold base 31 from being over-pressed and causing damage to the aluminum plate, making it easy to use.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
