Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel processing technology, and in particular to a bidirectional stepped pressure bending forming mold for honeycomb panel production. Background Technology

[0002] A honeycomb panel is a sheet material made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material; it is also known as a honeycomb sandwich structure. In addition, a honeycomb panel can also refer to a panel that welds a large number of cutoff waveguides together to form a cutoff waveguide array, creating a large opening area while preventing electromagnetic wave leakage.

[0003] Currently, honeycomb panels are widely used in various industries due to their lightweight, high strength, and excellent thermal insulation properties. However, in the traditional honeycomb panel production process, the bending and forming step often relies on a unidirectional press or manual operation.

[0004] While unidirectional presses can achieve mass production, uneven pressure distribution can easily lead to deformation and cracking of the sheet metal, resulting in unstable product quality. Manual bending is more flexible, but it is labor-intensive, has low production efficiency, and requires highly skilled operators, making it unsuitable for large-scale production. Utility Model Content

[0005] This utility model addresses the shortcomings of unidirectional presses, which, while enabling mass production, suffer from uneven pressure distribution leading to sheet deformation and cracking, resulting in inconsistent product quality. Manual bending offers greater flexibility but is labor-intensive and inefficient. The present invention provides a bidirectional, stepped pressure bending forming mold for honeycomb panel production. The specific technical solution is as follows:

[0006] A bidirectional stepped pressure bending forming mold for producing honeycomb panels includes a lower mold body, a honeycomb panel body installed on the top of the lower mold body, and an upper mold body disposed on the top of the lower mold body for vertically pressing the honeycomb panel body to induce bending. The top of the lower mold body is provided with an arc-shaped groove, and the bottom of the upper mold body is provided with an arc-shaped protrusion for pressing the honeycomb panel body into the arc-shaped groove. Both ends of the honeycomb panel body are provided with pressure members for laterally pressing the honeycomb panel body to induce bending. The pressure members are located between the lower mold body and the upper mold body.

[0007] A positioning mechanism is provided between the lower mold body and the upper mold body, and an ejector mechanism is provided at the top of the lower mold body for automatically ejecting the honeycomb panel that is adhered to the lower mold body after bending and forming.

[0008] By adopting the above technical solution, the upper mold body applies vertical pressure to the honeycomb panel, and the pressure-applying components apply horizontal pressure to the honeycomb panel, thereby achieving bidirectional stepwise pressure on the honeycomb panel. This ensures uniform pressure distribution within the honeycomb panel, avoids local overload and deformation problems in traditional methods, and improves the quality and stability of honeycomb panel bending and forming.

[0009] Optionally, the positioning mechanism includes a plurality of positioning holes formed at the top edge of the lower mold body, and a positioning rod fixed at the bottom edge of the upper mold body and inserted into the positioning holes.

[0010] By adopting the above technical solution, after the positioning rod is inserted into the matching positioning hole, it can vertically position the lower mold body and the upper mold body, so that the upper mold body can be vertically pressed on the lower mold body.

[0011] Optionally, the ejector mechanism includes an arc-shaped top plate that abuts against the bottom of the honeycomb panel, and several return springs fixedly disposed in the lower mold body for pushing the arc-shaped top plate toward the honeycomb panel. A limit groove is provided at the bottom of the arc-shaped groove of the lower mold body, and the top of the arc-shaped top plate is slidably disposed in the corresponding limit groove. The return spring is fixedly connected to the bottom of the limit groove of the lower mold body, and a telescopic rod for limiting the arc-shaped top plate is fixedly disposed between the bottom surface of the arc-shaped top plate and the bottom of the limit groove.

[0012] By adopting the above technical solution, the elastic force of the reset spring can enable the arc-shaped top plate to automatically push the bent honeycomb panel out of the lower mold body, thereby speeding up the feeding of the honeycomb panel.

[0013] Optionally, the lower mold body has a relief groove on its outer wall that communicates with the limiting groove. A rotating rod is rotatably connected in the relief groove of the lower mold body. A push rod is fixedly provided on one side of the bottom of the arc-shaped top plate. A rotating plate is fixedly provided on the outer wall of the rotating rod and abuts against the bottom of the push rod. The rotating rod is located at the end of the rotating plate near the arc-shaped top plate. An anti-slip pad located outside the lower mold body is fixedly provided at the top of the end of the rotating plate away from the arc-shaped top plate.

[0014] By adopting the above technical solution, when the honeycomb panel is too firmly bonded to the lower mold body and the arc-shaped top plate cannot eject it, pressing down on one end of the rotating plate can cause the other end of the rotating plate to push the arc-shaped top plate upward, thereby ejecting the honeycomb panel that is too firmly bonded and unloading it, which facilitates demolding.

[0015] In summary, this utility model has at least one of the following beneficial effects:

[0016] 1. By applying vertical pressure to the honeycomb panel through the upper mold and lateral pressure to the honeycomb panel through the pressure-applying components, bidirectional stepwise pressure is applied to the honeycomb panel, ensuring uniform pressure distribution within the honeycomb panel. This avoids the local overload and deformation problems of traditional methods, improves the quality and stability of honeycomb panel bending and forming, and allows for rapid batch bending and forming of honeycomb panels by installing the mold on equipment such as presses, thereby improving production efficiency and meeting the needs of large-scale production.

[0017] 2. The return spring's elasticity allows the curved top plate to automatically eject the bent honeycomb panel from the lower mold, accelerating the honeycomb panel's unloading. When the honeycomb panel is too firmly adhered to the lower mold and the curved top plate cannot eject it, pressing down on one end of the rotating plate will cause the other end of the rotating plate to lift the curved top plate upwards, thus ejecting the firmly adhered honeycomb panel for unloading. This facilitates demolding. Furthermore, since the rotating rod is located at the end of the rotating plate near the curved top plate, lever principle allows workers to press down the rotating rod with less effort, making it convenient and practical.

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0024] This utility model discloses a bidirectional stepped pressure bending forming mold for honeycomb panel production, referring to... Figure 1-2It includes a lower mold body 1, a honeycomb panel 2, and an upper mold body 3. The lower mold body 1 can be installed on the workbench of a press or other pressure equipment. The honeycomb panel 2 is installed on the top of the lower mold body 1. The upper mold body 3 is located on the top of the lower mold body 1 and can be installed at the bottom of the hydraulic cylinder of the press or other pressure equipment. By extending the hydraulic cylinder of the external pressure equipment, the upper mold body 3 is driven to move downward, thereby applying vertical pressure to the honeycomb panel 2 to cause the honeycomb panel 2 to bend.

[0025] Reference Figure 1-2 The lower mold body 1 has an arc-shaped groove 11 at the top, and the upper mold body 3 has an arc-shaped protrusion 31 at the bottom for pressing the honeycomb panel 2 into the arc-shaped groove 11. After the upper mold body 3 moves down, it can press the honeycomb panel 2 into the arc-shaped groove 11 through the arc-shaped protrusion 31, thereby applying vertical pressure to the honeycomb panel 2 to cause the honeycomb panel 2 to bend and form.

[0026] Reference Figure 1-2 The honeycomb panel 2 is provided with pressure members 4 at both ends for applying lateral pressure to the honeycomb panel 2 to induce bending. The pressure members 4 are located between the lower mold body 1 and the upper mold body 3. The pressure members 4 can be pressed by the hydraulic cylinder of external equipment to apply lateral pressure to the honeycomb panel 2 through the pressure members 4 on both sides. By applying bidirectional stepwise pressure to the honeycomb panel 2 in both the lateral and vertical directions, the pressure distribution inside the honeycomb panel 2 is ensured to be uniform, avoiding the local overload and deformation problems in the traditional method, and improving the quality and stability of the bending and forming of the honeycomb panel 2.

[0027] Reference Figure 1-2 A positioning mechanism is provided between the lower mold body 1 and the upper mold body 3. The positioning mechanism includes several positioning holes 14 opened at the top edge of the lower mold body 1, and a positioning rod 32 fixed at the bottom edge of the upper mold body 3 and inserted into the positioning holes 14. After the positioning rod 32 is inserted into the matching positioning hole 14, it can vertically position the lower mold body 1 and the upper mold body 3, so that the upper mold body 3 can be vertically pressed on the lower mold body 1.

[0028] Reference Figure 2-4 The lower mold body 1 is provided with an ejector mechanism at its top for automatically ejecting the honeycomb plate 2 that is adhered to the lower mold body 1 after bending and forming. The ejector mechanism includes an arc-shaped top plate 5 that abuts against the bottom of the honeycomb plate 2, and several return springs 51 fixed in the lower mold body 1 for pushing the arc-shaped top plate 5 toward the honeycomb plate 2. Under the elastic force of the return springs 51, the arc-shaped top plate 5 will be pushed and pushed upward. When the honeycomb plate 2 is bent and formed and moves upward to the upper mold body 3, the arc-shaped top plate 5 will move upward under the elastic force and push the honeycomb plate 2 that is adhered to the top of the lower mold body 1 away and automatically eject it from the lower mold body 1 to speed up the unloading of the honeycomb plate 2.

[0029] Reference Figure 2-3The bottom of the arc groove 11 of the lower mold body 1 is provided with a limiting groove 12. The top of the arc top plate 5 is slidably disposed in the matching limiting groove 12. The reset spring 51 is fixedly connected to the bottom of the limiting groove 12 of the lower mold body 1. The lower mold body 1 can support and limit the arc top plate 5 through the limiting groove 12, so that when the honeycomb plate 2 is subjected to vertical pressure from the upper mold body 3, it can be stored in the top of the matching limiting groove 12, so as not to hinder the bending and forming of the honeycomb plate 2.

[0030] Reference Figure 2-3 A telescopic rod 52 for limiting the arc-shaped top plate 5 is fixed between the bottom surface of the arc-shaped top plate 5 and the bottom of the limiting groove 12. The telescopic rod 52 can further connect the arc-shaped top plate 5 and the lower mold body 1, and further limit the arc-shaped top plate 5, so that the arc-shaped top plate 5 can only move up and down.

[0031] Reference Figure 2-3 The lower mold body 1 has a relief groove 13 on its outer wall that communicates with the limiting groove 12. A rotating rod 54 is rotatably connected in the relief groove 13 of the lower mold body 1. The lower mold body 1 can support and limit the rotating rod 54 through the relief groove 13.

[0032] Reference Figure 2-3 A push rod 53 is fixedly provided on one side of the bottom of the arc-shaped top plate 5. A rotating plate 55 is fixedly provided on the outer wall of the rotating rod 54, which abuts against the bottom of the push rod 53. The clearance groove 13 provides space for the rotating plate 55 to rotate, and the clearance groove 13 can limit the rotation range of the rotating plate 55. The rotating rod 54 can support and fix the rotating plate 55. When the honeycomb plate 2 is too firmly attached to the lower mold 1 and the arc-shaped top plate 5 cannot automatically push it out under the elastic force, the operator can press down one end of the rotating plate 55 and, with the rotation of the rotating rod 54, make the rotating plate 55 rotate like a seesaw, so that the other end of the rotating plate 55 pushes the arc-shaped top plate 5 upward, and pushes the honeycomb plate 2 out of the firmly attached lower mold 1 for unloading, which is convenient for demolding.

[0033] Reference Figure 2-3 The rotating rod 54 is located at one end of the rotating plate 55 near the arc-shaped top plate 5. The top of the rotating plate 55 away from the arc-shaped top plate 5 is fixed with an anti-slip pad 56 located outside the lower mold body 1. The rotating rod 54 can separate the two ends of the rotating plate 55, making the end of the rotating rod 54 near the arc-shaped top plate 5 shorter and the end of the rotating rod 54 near the anti-slip pad 56 longer. Thus, under the lever theorem, the force required by the worker to press down the arc-shaped top plate 5 is reduced, making it more labor-saving. The anti-slip pad 56 makes it less likely for the worker to slip when pressing down the arc-shaped top plate 5.

[0034] The implementation principle of a bidirectional stepped pressure bending forming mold for honeycomb panel production according to an embodiment of this utility model is as follows:

[0035] In use, the honeycomb panel 2 is placed between the lower mold 1 and the upper mold 3. Then, the upper mold 3 is moved down by an external press or other equipment. After the upper mold 3 moves down, the honeycomb panel 2 can be pressed into the arc groove 11 by the arc protrusion 31, thereby applying vertical pressure to the honeycomb panel 2 to make it bend and form.

[0036] Then, the upper mold body 3 is subjected to vertical pressure holding. At the same time, the pressure-pressing components 4 on both sides are used to apply horizontal pressure to the honeycomb panel 2. The honeycomb panel 2 is subjected to vertical and horizontal pressure holding for a period of time to achieve the overall bending and forming of the honeycomb panel 2. By applying horizontal and vertical pressure in a two-way stepped manner to the honeycomb panel 2, the pressure distribution inside the honeycomb panel 2 is ensured to be uniform, avoiding the local overload and deformation problems in the traditional method, and improving the quality and stability of the bending and forming of the honeycomb panel 2.

[0037] After bending and forming, the upper mold body 3 is moved upward, so that the upper mold body 3 is separated from the bent honeycomb plate 2. At this time, the arc-shaped top plate 5 will move upward under the elastic force of the return spring 51, and push away the honeycomb plate 2 that is attached to the top of the lower mold body 1, so as to automatically eject the honeycomb plate 2 and speed up the unloading of the honeycomb plate 2.

[0038] When the honeycomb panel 2 is too firmly bonded to the lower mold 1 and the arc-shaped top plate 5 cannot automatically eject it under elastic force, the operator can press down on one end of the rotating plate 55 and, in conjunction with the rotation of the rotating rod 54, make the rotating plate 55 rotate like a seesaw, so that the other end of the rotating plate 55 pushes the arc-shaped top plate 5 upward, thereby ejecting the honeycomb panel 2 from the firmly bonded lower mold 1 for unloading, which facilitates demolding.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
