Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb panel forming technology, specifically to a CNC deformable mold mechanism for vacuum forming of aluminum honeycomb panels. Background Technology

[0002] Aluminum honeycomb panels are a common building material. Due to the excellent properties of honeycomb materials, such as high wind pressure resistance, shock absorption, sound insulation, heat insulation, flame retardancy, and high specific strength, aluminum honeycomb panels have become the mainstream building material.

[0003] To meet the requirements of building shape, aluminum honeycomb panels are usually processed into curved shapes. Current technology uses a stretching machine for forming. During forming, a wooden mold is first placed at the bottom of the aluminum honeycomb panel. Through stretching, the aluminum honeycomb panel gradually fits completely with the wooden mold until the final curved shape is formed.

[0004] Because the curvature of aluminum honeycomb panels of different specifications varies greatly, a wooden mold needs to be made for each molding process, which creates a huge workload. At the same time, the frequent replacement of wooden molds also reduces processing efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a CNC deformable mold mechanism for vacuum forming of aluminum honeycomb panels, which solves the problem of low efficiency in existing aluminum honeycomb panel forming mechanisms.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a CNC deformable mold mechanism for vacuum forming of aluminum honeycomb panels, including a machine base, on which multiple sets of independently driveable servo electric cylinders are arranged, and a universal joint is provided on the top of each servo electric cylinder, and a controllable deformable template is fixed on the top of the universal joint.

[0009] The top of the controllable deformation template is provided with a limiting area, in which an aluminum honeycomb panel is placed. The top of the aluminum honeycomb panel is covered with a flexible membrane that can be vacuumed, and a vacuum port and a pressure relief valve are respectively provided on the flexible membrane.

[0010] As a further preferred embodiment, the flexible membrane is provided with sleeves at all four corners, and the sleeves can be fitted onto the four sides of the controllable deformation template.

[0011] As a further preferred embodiment, the limiting area is provided with adhesive application points for fixing the honeycomb panel components.

[0012] (III) Beneficial Effects

[0013] This utility model provides a CNC deformable mold mechanism for vacuum forming of aluminum honeycomb panels. It has the following beneficial effects:

[0014] This aluminum honeycomb panel vacuum forming CNC deformable mold mechanism creatively introduces a controllable deformable mold. By arranging several independently driven servo cylinders, it can create shapes of arbitrary curvature, thus forming a template structure with the target curvature. The curvature of the template can be changed simply by changing the extension length of the servo cylinders. Then, a flexible film is wrapped around the outside of the template. By evacuating the flexible film, the aluminum honeycomb panel is tightly pressed onto the template using negative pressure, forming a curvature consistent with the template. Finally, after opening the pressure relief valve to restore the air pressure, the formed aluminum honeycomb panel can be removed. This device not only saves template costs but also improves processing efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a CNC deformable mold mechanism for vacuum forming of aluminum honeycomb panels, including a machine base 1. The machine base 1 is equipped with multiple sets of independently driveable servo cylinders 2. Each servo cylinder 2 has a universal joint 3 on its top. The top of the universal joint 3 is fixedly connected to a controllable deformable template 4 by screws. The universal joint 3 allows for a certain angular offset between the controllable deformable template 4 and each servo cylinder 2, thereby adapting to the forming process of the controllable deformable template 4.

[0022] The top of the controllable deformation template 4 is provided with a limiting area 5, which can be formed by manual scribing. The limiting area 5 is provided with glue application points 10 for fixing the honeycomb panel processing part 6. The aluminum honeycomb panel processing part 6 is placed in the limiting area 5. Regarding the aluminum honeycomb panel processing part 6, since it is a three-layer structure, the middle is honeycomb material and the two sides are thin aluminum plates. The honeycomb material and the thin aluminum plates are bonded with glue. Therefore, the forming work is carried out after the glue is applied and the forming is completed before the glue dries. The glue application points 10 are set to prevent the aluminum honeycomb panel processing part 6 from accidentally slipping off the controllable deformation template 4. After stretching, the glue application points 10 are cut open with a blade and the aluminum honeycomb panel is removed. Of course, we can also fix it by setting suction cup buckles on the front and rear sides of the aluminum honeycomb panel processing part 6.

[0023] The top of the aluminum honeycomb panel 6 is covered with a flexible membrane 7 that can be vacuumed. Under normal circumstances, the flexible membrane 7 is filled with air. After vacuuming, the flexible membrane 7 collapses rapidly and presses the aluminum honeycomb panel 6 tightly downward under negative pressure, forcing the aluminum honeycomb panel 6 to yield and adhere to the surface of the controllable deformation template 4, and forming a consistent arc with the controllable deformation template 4. Each of the four corners of the flexible membrane 7 is provided with a sleeve 8, which can be fitted onto the four sides of the controllable deformation template 4. The flexible membrane 7 is provided with a vacuum port 9 and a pressure relief valve 11.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] In use, the first step is to fix the controllable deformation template 4 to the universal joint 3 on the top of each servo cylinder 2. Then, the extension length of each servo cylinder 2 is calculated by the industrial control system (e.g., a PLC system; the control system is existing technology and will not be described in detail). Then, the servo cylinders 2 at each position are driven to extend the corresponding length, and all the servo cylinders 2 work together to form the desired arc (e.g., ...). Figure 2 (as shown), thereby shaping the controllable deformable template 4 to the target curvature.

[0026] Then, apply glue to the glue application point 10, place the aluminum honeycomb panel 6 on the limiting area 5 and fix it with glue. Then, put the sleeves 8 on the four sides of the flexible film 7 (which can be made of plastic or cotton cloth and fixed to the flexible film 7 by adhesive or other means) on the four sides of the controllable deformation template 4. Then, connect an external vacuum pump through the vacuum port 9 to perform vacuuming. After the flexible film 7 is vacuumed, it will generate a strong negative pressure, which is applied to the aluminum honeycomb panel 6, forcing the aluminum honeycomb panel 6 to yield and adhere to the surface of the controllable deformation template 4 and form a consistent arc with the controllable deformation template 4, thereby achieving the molding purpose.

[0027] Finally, open the pressure relief valve 11, the flexible diaphragm 7 restores the air pressure, releases the pressure, and the aluminum honeycomb panel processing part 6 can be removed.

[0028] In summary, this CNC deformable mold mechanism for vacuum forming of aluminum honeycomb panels creatively introduces a controllable deformable mold. By arranging several independently driven servo cylinders, it creates shapes of arbitrary curvature, thereby forming a template structure with the target curvature. A flexible film is then wrapped around the outside of the template. By evacuating the flexible film, negative pressure is used to tightly press the aluminum honeycomb panel onto the template, forming a curvature consistent with the template. Finally, after opening the pressure relief valve to restore the air pressure, the formed aluminum honeycomb panel can be removed. This device not only saves template costs but also improves processing efficiency.
