DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example 1, as Figure 1 and Figure 2 As shown, a stamping device for producing UAV wings includes a base 1, a control box 5 is fixedly installed at the front end of the base 1, a bracket 2 is fixedly connected to the rear end of the base 1, a hydraulic cylinder 8 is fixedly installed on the upper end of the bracket 2, the lower end of the hydraulic cylinder 8 is fixedly connected to an upper mold 4 that is slidably connected to the bracket 2, the upper end of the base 1 is fixedly connected to a lower mold 3, the inner cavity of the base 1 is provided with a conveying and rotating assembly 6, and the right part of the upper end of the base 1 is provided with a heating and oil brushing assembly 7.

[0032] During the implementation of this embodiment, the wing rib blank is placed in the conveying and rotating assembly 6, and then the control box 5 is operated to automatically clamp the wing rib blank during its movement to the left, and then the wing rib blank is driven to flip over, and during the flipping process, it is heated by the heating and oiling assembly 7, and lubricating oil is applied to its upper and lower ends after heating. When the wing rib blank is transported to the set position by the conveying and rotating assembly 6, the upper mold 4 is driven downward by the hydraulic cylinder 8, so that the wing rib blank placed on the lower mold 3 is stamped. After the stamping operation is completed, the conveying and rotating assembly 6 takes away the excess waste, and the stamped ribs are ejected from the lower mold 3.

[0033] It should be noted that the control box 5 and hydraulic cylinder 8 mentioned above are both mature technical means and equipment in the existing technology and belong to conventional technical design. Their internal structure, connection method and principle will not be elaborated in this solution.

[0034] Specifically, in order to realize the clamping and rotation of the UAV wing rib blank, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In this embodiment, the conveying and rotating component 6 is provided with a slide groove 61 which is symmetrical with the upper end of the base 1 in front and back. The inner surfaces of the two slide grooves 61 are jointly provided with a conveying mechanism 62. The inner surface of the conveying mechanism 62 is symmetrically provided with a clamping and rotating mechanism 63. The inner surface of the lower mold 3 and the inner surface of the base 1 are jointly provided with an ejection mechanism 65.

[0035] For further information, see Figure 4 and Figure 5 In this embodiment, the conveying mechanism 62 includes a threaded rod 621 rotatably connected to the inner surface of the base 1, a rotating rod 1 622 is rotatably connected to the front of the inner surface of the base 1, the outer surface of the rotating rod 1 622 and the outer surface of the threaded rod 621 are fixedly connected to a transmission mechanism 624, the front end of the rotating rod 1 622 is fixedly connected to a dual-axis motor 623 fixedly connected to the front end of the base 1, the outer surface of the threaded rod 621 is threadedly connected to a concave plate 625 slidably connected to the inner surface of the slide 61, and the front output end of the dual-axis motor 623 is fixedly connected to the rotating rod 2 626 through a coupling.

[0036] For further information, see Figure 3 、 Figure 4 and Figure 6 In this embodiment, the clamping rotation mechanism 63 includes a round block 631 rotatably connected to the inner surface of the concave plate 625, a concave block 632 is fixedly connected to the front end of the round block 631, a cylinder 633 fixedly connected to the concave plate 625 is rotatably connected to the inner surface of the round block 631, a piston rod 634 is slidably connected to the inner surface of the cylinder 633, and a spring 635 is sleeved on the outer surface of the piston rod 634. The two ends of the spring 635 are respectively connected to the inner surface of the cylinder 633 and the piston rod 634. The piston on it is fixedly connected, the lower part of the outer surface of the piston rod 1 634 is rotatably connected to the slider 636, the inner surface of the concave block 632 is fixedly connected to the cylinder 2 637, the inner surface of the cylinder 2 637 is slidably connected to the piston fixing plate 638, the inner surface of the cylinder 1 633 passes through and extends to the inner surface of the cylinder 2 637 and is fixedly connected to the connecting pipe 639, the connecting pipe 639 is rotatably connected to the cylinder 1 633, and the upper end of the base 1 is symmetrically provided with guide grooves 6310 which are slidably connected to the slider 636.

[0037] During implementation, the wing rib blank is placed between the two concave blocks 632. The rear output end of the dual-axis motor 623 is then started to drive the rotating rod 1 622 to rotate through the coupling. Under the action of the transmission mechanism 624, the threaded rod 621 rotates. Since the concave plate 625 is threadedly connected to the threaded rod 621, the concave plate 625 moves to the left, thereby driving the wing rib blank to move.

[0038] Secondly, during the movement, since the two guide grooves 6310 are convex, the slider 636 on the piston rod 1 634 can slide on the inner surface of the cylinder 1 633 while sliding on the inner surface of the guide groove 6310, so that the piston on the piston rod 1 634 will squeeze the hydraulic oil in the cylinder 1 633 into the cylinder 2 637 through the connecting pipe 639, and then push the piston fixing plate 638 to move downward, so that the wing rib blank placed on the concave block 632 is fixed, and automatic fixing operation can be realized during the loading process of the wing rib blank. The automatic fixing process can improve the accuracy and stability of the stamping operation, reduce manual intervention, ensure that the blank does not move during the stamping process, and improve production efficiency and finished product quality.

[0039] The inner cavity of the cylinder 633 is filled with hydraulic oil.

[0040] The transmission mechanism 624 mentioned above is composed of two bevel gears.

[0041] For further information, see Figure 3 、 Figure 4 and Figure 6 In this embodiment, a gear 6311 is fixedly connected to the outer surface of the round block 631, and a rack 6312 is fixedly connected to the upper end of the base 1 symmetrically in front and back, and the gear 6311 is meshed with the rack 6312.

[0042] During implementation, when the gear 6311 on the round block 631 engages with the rack 6312 on the base 1, since the connecting tube 639 and the cylinder 1 633 are rotationally connected, the gear 6311 will drive the round block 631 to rotate on the inner surface of the concave plate 625, thereby driving the fixed wing rib blank to flip.

[0043] After the gear 6311 and the rack 6312 are engaged, the wing rib blank is still parallel to the base 1, and there is a certain resistance to the rotation between the round block 631 and the concave plate 625.

[0044] For further information, see Figure 4 、 Figure 5 and Figure 7In this embodiment, the ejection mechanism 65 includes ejection rods 651 that are symmetrically connected to the inner surface of the lower mold 3 and extend to the lower part of the inner surface of the base 1 for sliding connection. The lower ends of the two ejection rods 651 are fixedly connected to a connecting plate 652. The inner surface of the connecting plate 652 is rotatably connected to a roller 654. The outer surfaces of the two ejection rods 651 are both sleeved with springs 653. The two ends of the two springs 653 are respectively fixedly connected to the upper end of the connecting plate 652 and the lower part of the inner surface of the base 1. The right end of the concave plate 625 is fixedly connected to a trapezoidal extrusion plate 655.

[0045] As can be seen from the above, after the stamping of the wing rib blank is completed, the conveying mechanism 62 and the clamping and rotating mechanism 63 will drive the waste material to continue to move to the left. During the movement, the trapezoidal extrusion plate 655 at the rear end of the concave plate 625 will contact the outer surface of the roller 654, so that the trapezoidal extrusion plate 655 will gradually squeeze the roller 654, pushing the two ejector rods 651 to move upward, so that the spring 2 653 is in a compressed state, and the two ejector rods 651 will eject the stamped wing ribs from the lower mold 3. The stamped wing ribs can be demolded smoothly to avoid jamming or deformation, while improving production efficiency, reducing manual intervention, reducing operating risks and labor intensity, ensuring the consistency and stability of product quality, and improving the accuracy and production efficiency of the overall stamping operation.

[0046] Embodiment 2: Based on embodiment 1, this embodiment further includes a heating and oiling component 7 for heating and oiling the blank before stamping, thereby achieving the purpose of heating and oiling the blank before stamping.

[0047] Specifically, in order to heat and oil the blank before stamping, refer to Figure 8 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, the heating oil brushing assembly 7 includes a rectangular frame 71 symmetrically fixedly connected to the upper end of the base 1, a heating mechanism 72 is provided at the front end of the base 1, and an oil brushing mechanism 73 is jointly provided at the upper end of the upper rectangular frame 71 and the upper inner surface of the base 1.

[0048] For further information, see Figure 4 and Figure 8In this embodiment, the heating mechanism 72 includes a circular hole frame 721 fixedly connected to the front end of the base 1, and a round rod 722 is rotatably connected to the inner surface of the circular hole frame 721. The outer surface of the circular rod 722 is located in the inner cavity of the circular hole frame 721 and is fixedly connected to the fan blade 724. A heating box 725 is fixedly installed at the front end of the base 1. The heating box 725 is connected to the inner surface of the circular hole frame 721 through a pipe. The upper end of the heating box 725 passes through and extends to the inner surface of the upper rectangular frame 71 and is fixedly connected to a blowing pipe 726. The outer surface of the circular rod 722 and the outer surface of the rotating rod 2626 are jointly fixedly connected to a pulley group 723.

[0049] During the implementation process, when the wing rib blank is being loaded, conveyed and flipped, the front end output end of the dual-axis motor 623 is started to drive the rotating rod 2 626 to rotate through the coupling, and under the transmission action of the pulley group 723, the fan blades 724 on the round rod 722 are driven to rotate. The rotation of the fan blades 724 sucks air into the inside of the circular hole frame 721 and enters the heating box 725 through the pipe. The air is heated by the heating box 725, and the heated air enters the two rectangular frames 71 through the blower pipe 726. First, the dust on the outer surface of the wing rib blank can be cleaned, and at the same time, the flipped wing rib blank is heated, so that the blank is evenly heated during the flipping process, which can ensure that the entire material is heated evenly, reduce local overheating or overcooling, thereby improving the plasticity of the material, reducing the risk of deformation and cracks, optimizing the stamping performance, improving the forming accuracy, and reducing the stress and brittleness of the material, thereby improving the stability and production efficiency of the stamping process.

[0050] The heating box 725 mentioned above is a mature heating technology means and equipment in the prior art. In this solution, its function of heating the air is utilized, and its internal structure, connection method and principle are no longer elaborated.

[0051] The dual-axis motor 623 mentioned above is a mature driving technology means and equipment in the existing technology. In this solution, the couplings on both sides thereof can rotate independently and can stop after rotating to a set number of circles. Its internal structure, connection method and principle will not be elaborated further.

[0052] For further information, see Figure 4 、 Figure 5 、 Figure 9 and Figure 10In this embodiment, the oil brushing mechanism 73 includes two oil tanks 731 fixedly connected to the lower part of the inner surface of the base 1 and the upper end of the upper rectangular frame 71. The rear ends of the two oil tanks 731 are fixedly connected to hollow blocks 736. The inner surfaces of the two rectangular frames 71 are symmetrically fixedly connected to fixed frames 732. The inner surfaces of the two fixed frames 732 are fixedly connected to sponge blocks 733. The inner surfaces of the two hollow blocks 736 are slidably connected to piston rods 2 734. The outer surfaces of the two piston rods 2 734 are both sleeved with springs 3 735. The two ends of spring three 735 are respectively fixedly connected to the lower inner surface of hollow block 736 and the piston on piston rod two 734. The upper inner surfaces of the two hollow blocks 736 pass through and extend to the inner surface of the fixed frame 732 and are fixedly connected to connecting pipes 737. The lower ends of the two connecting pipes 737 are fixedly connected to one-way valve one 738. The inner surfaces of the two oil tanks 731 pass through and extend to the inner surface of the hollow block 736 and are fixedly connected to one-way valve two 739. Two arc-shaped extrusion rods 7310 are fixedly connected to the rear left end of the concave plate 625.

[0053] During the implementation process, the concave plate 625 will drive the two arc-surface extrusion rods 7310 to move as it moves to the left, and squeeze the piston rod 2 734, so that the spring 3 735 is in a compressed state, so that the piston rod 2 734 squeezes the lubricating oil in the inner cavity of the hollow block 736 into the connecting pipe 737 through the one-way valve 1 738, and then enters the sponge block 733. When the piston rod 2 734 is no longer squeezed, the lubricating oil in the oil tank 731 is sucked into the inner cavity of the hollow block 736 through the one-way valve 2 739 under the compression reaction of the spring 3 735, and the lubricating oil is applied to the upper and lower ends of the wing rib blank, thereby reducing friction during the stamping process, effectively reducing the friction between the mold and the blank, reducing wear and temperature rise, avoiding excessive wear of the material or surface damage, thereby improving stamping accuracy, extending the service life of the mold, reducing molding defects, and improving overall production efficiency and product quality.

[0054] The one-way valve 1 738 and the one-way valve 2 739 mentioned above are the one-way control technical means and equipment of the vehicle number in the prior art. In this solution, they are used to control the flow direction of the liquid, and their internal structure and principles are not further explained.

[0055] Working process: When in use, the wing rib blank is automatically clamped and fixed during the loading process by the conveying mechanism 62 and the clamping and rotating mechanism 63, and the wing rib blank is turned over during the conveying process. During the turning process, the heating mechanism 72 is used to evenly heat it, and the dust attached to the outer surface of the wing rib blank can be cleaned. Secondly, lubricating oil is automatically applied to the outer surface of the wing rib blank during the conveying process. After the stamping is completed, the formed wing rib is ejected from the inner cavity of the lower mold 3 by the ejection mechanism 65.
