Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel forming technology, specifically to a forming device for hyperbolic aluminum single panels. Background Technology

[0002] In the field of building curtain walls, hyperbolic aluminum panels are widely used in high-end building facades due to their unique curved shape. These aluminum panels exhibit a continuous V-shaped wave structure in the width direction, while also possessing spatial curvature in the length direction (e.g., ...). Figure 1 As shown in the figure, it forms a complex hyperbolic geometric shape.

[0003] When forming this type of hyperboloid aluminum panel, a metal bending machine is first used to press V-shaped waves in the width direction, and then the semi-finished product is transferred to a stamping machine to form the arc in the length direction. However, because the finished size of this type of aluminum panel is large (about 3m in length and 1-2m in width), the stamping mold required is huge. The stamping mold is often made of metal mold (usually 45# steel or mold steel), which is expensive and has a long processing cycle.

[0004] For small to medium batch orders (e.g., ≤50 pieces), the price of a single hyperboloid aluminum panel increases dramatically after the cost of the mold is allocated. In addition, the metal stamping mold is large in size and constitutes a heavy mold, requiring large forklifts for transportation, which increases the requirements for supporting equipment. Utility Model Content

[0005] The present invention aims to provide a forming device for hyperbolic aluminum panels to solve the problems of high stamping die cost and long production cycle in the existing technology for processing small and medium batches of hyperbolic aluminum panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A forming device for hyperbolic aluminum single panel includes a punch press with a support platform and a pressure plate located above the support platform. The pressure plate is liftable. An upper mold is installed at the bottom of the pressure plate, and a lower mold is installed on the support platform. After the upper mold and the lower mold are closed, a hyperbolic cavity of the aluminum single panel is formed. Both the upper mold and the lower mold are wooden molds. Both the upper mold and the lower mold are composed of at least two sub-modules spliced ​​along the length of the mold, and adjacent sub-modules are fixedly connected.

[0007] Preferably, as an improvement, adjacent sub-modules are laterally connected by pry bar studs.

[0008] Preferably, as an improvement, adjacent sub-modules are connected by at least two rivets, and the rivets are not parallel to each other.

[0009] Preferably, as an improvement, the submodule is a solid wood component with a wood density ranging from 0.6 to 1.2 g / cm³. 3 .

[0010] Preferably, as an improvement, the upper mold is fixed to the pressure plate by straps, and the pressure plate is detachably connected to a metal plate by bolts, with the metal plate and the upper mold being laterally anchored by multiple steel nails.

[0011] Preferably, as an improvement, each sub-module has at least two through holes in the middle, the through holes are oriented along the length of the mold, the through holes at the same position of all sub-modules are coaxially aligned, and the through holes at the same position are used to insert a metal rod.

[0012] Preferably, as an improvement, the end of the metal rod is connected through the metal plate of the pressure plate.

[0013] Preferably, as an improvement, the metal rod is a hollow metal tube to reduce weight and cost while ensuring strength.

[0014] Advantages of this utility model: 1. This utility model uses a wooden mold instead of a metal mold, which greatly reduces the cost of the mold. Since there is no need for the mold manufacturer to make the metal mold, the manufacturer can process multiple sub-modules and assemble them. Therefore, the mold opening cycle is also greatly shortened. The original mold opening cycle of metal mold is about one month. After the manufacturer processes the wooden sub-molds, the mold opening cycle is shortened to 3 days. Thus, the mold cost is reduced while the mold opening cycle is greatly shortened.

[0015] 2. The multi-module splicing design can avoid using whole giant logs (logs with a diameter of ≥1m) and can be replaced with conventional wood, which helps to significantly reduce raw material costs.

[0016] 3. Non-parallel studs allow adjacent sub-modules to be connected by studs with different tilt angles, which helps to improve shear strength, prevent the sub-dies from shifting during stamping, and improve the connection stability between adjacent sub-dies.

[0017] 4. This solution uses straps, metal plates, steel nails for anchoring, and metal rods to easily fix the upper mold to the pressure plate, reducing the difficulty of installing the upper mold. At the same time, the metal rods connect the middle of the sub-modules, which helps to improve the overall rigidity of the assembled mold. Attached Figure Description

[0026] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: punch press 1, hydraulic cylinder 11, support platform 2, pressure plate 3, upper die 4, lower die 5, sub-module 41, through hole 411, pin 6, connecting plate 7, metal plate 8, metal rod 9, strapping 10.

[0027] The basic implementation examples are as follows: Figures 2 to 8 As shown.

[0028] A forming device for hyperbolic aluminum single panel includes a punch press 1, which has a support platform 2 and a pressure plate 3 located above the support platform 2. The pressure plate 3 is driven to rise and fall under the action of hydraulic cylinders 11. In this embodiment, there are 4 hydraulic cylinders 11. The 4 hydraulic cylinders 11 work synchronously to drive the pressure plate 3 to rise and fall smoothly. An upper mold 4 is installed at the bottom of the pressure plate 3, and a lower mold 5 is installed on the support platform 2. After the upper mold 4 and the lower mold 5 are closed, a hyperbolic cavity of the aluminum single panel is formed. Both the upper mold 4 and the lower mold 5 are wooden molds. Both the upper mold 4 and the lower mold 5 are composed of at least two sub-modules 41 spliced ​​along the length of the mold.

[0029] Adjacent sub-modules 41 are connected laterally by at least two rivets 6. The rivets 6 are not parallel to each other, and the rivets 6 can be forged rivets 6.

[0030] Each submodule 41 is a solid wood component, and the wood density of submodule 41 ranges from 0.6 to 1.2 g / cm3.

[0031] Each submodule 41 is identical in the mold width direction.

[0032] The lower mold 5 is placed on the support platform 2. To ensure that the lower mold 5 does not shift, an L-shaped connecting plate 7 is provided on the support platform 2. The L-shaped connecting plate 7 is detachably connected to the support platform 2 by bolts, and is also fixedly connected to the end sub-module 41 by steel nails. The L-shaped connecting plate 7 has multiple mounting holes for inserting steel nails along the width direction of the mold.

[0033] The upper mold 4 is fixed to the pressure plate 3 by the strap 10, and the pressure plate 3 is detachably connected to the metal plate 8 by bolts. The metal plate 8 is also L-shaped. The metal plate 8 and the sub-module 41 on the end side of the upper mold 4 are laterally anchored by multiple steel nails. Similarly, in order to facilitate riveting on the metal plate 8, the metal plate 8 is also provided with multiple through holes 411 along the width direction of the mold to facilitate the insertion of steel nails.

[0034] Each submodule 41 has at least two through holes 411 in the middle, the direction of the through holes 411 is the mold length direction, the through holes 411 at the same position of all submodules 41 are coaxially aligned, and the through holes 411 at the same position are used to install metal rods 9 through.

[0035] The end of the metal rod 9 inserted into the upper mold 4 is connected to the metal plate 8 of the pressure plate 3.

[0036] Metal rod 9 is a hollow metal tube.

[0037] In this embodiment, a wooden mold is used instead of a metal mold, which greatly shortens the mold making cycle. Furthermore, the cost of the mold can be significantly reduced by using wooden sub-modules 41 to assemble the mold.

[0038] In addition, wooden molds are more resilient than metal molds. When stamping hyperboloid aluminum panels, the hyperboloid aluminum panels are longer, and the forming quality is better when the hyperboloid aluminum panels are formed from a simple bending and wavy shape to a shape that has both bending and wavy shape and a curvature in the length direction. The aluminum panels are less likely to have obvious forming defects.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
