Description

Technical Field

[0001] This invention relates to the field of fairing stamping equipment technology, specifically to a drone fairing stamping device and method. Background Technology

[0002] Currently, drones are widely used in both military and civilian fields. In short, a drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or it can be fully or intermittently operated autonomously by an onboard computer. At present, it is used in many fields such as aerial photography, agriculture, plant protection, mini selfies, express delivery, disaster relief, and wildlife observation, which greatly expands the uses of drones.

[0003] Fairings are essential components for industrial drones. For example, fairings are installed at the very front of the fuselage, covering the propellers and engines, and are used to regulate airflow.

[0004] The patent (application number: CN202121804098.8) discloses a stamping device for producing alloy lampshades, including a worktable with support feet at the four corners of the lower side. A forming groove is provided on the upper side of the worktable, and a forming component is provided on the lower side of the output shaft of the hydraulic cylinder. A placement hole is provided at the bottom of the forming groove, and a through hole is provided on the lower inner wall of the placement hole. A limit hole is provided on the lower side of the through hole, and a reset component is provided at the bottom of the limit hole. A slider matching the reset component is slidably installed in the limit hole. A top plate matching the placement hole is fixedly connected to the upper end of the top rod. An installation component is provided on the lower side of the worktable and fixedly connected to the support feet. A pedal is hinged to the installation component, and a pulling mechanism is provided at the end of the pedal away from the hinge. The pulling mechanism matches the slider. After the lampshade is stamped, the operator can directly release the pedal, and the top plate will automatically lift upward, thereby pushing the lampshade out of the forming groove, making it easy for the operator to remove the lampshade.

[0005] The patent and existing technologies have the following technical problems in practical use:

[0006] 1. When the fairing is stamped, the material is generally stamped in one pass using a stamping head. Existing stamping equipment does not make it convenient to detect the springback of the material after stamping. Due to the plasticity of the metal material during stamping, there will always be an elastic change when the stamping head moves upward after stamping. After stamping, the stamped material will have a certain springback. If the springback material is not adjusted, the shape accuracy and dimensional accuracy of the formed material will change, thereby affecting the product quality and performance. Summary of the Invention

[0007] The purpose of this invention is to solve the above problems by providing a device and method for stamping a drone fairing.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0009] A stamping device and method for a drone fairing, comprising a worktable, with a detection component and an adjustment component respectively arranged above and below the worktable;

[0010] The detection component includes a sliding groove formed on the top of the workbench. Two sets of sliding grooves are symmetrically arranged. An electromagnet is fixedly connected to one side of the sliding groove, and a magnet is slidably connected to the side of the sliding groove away from the electromagnet. A clamping plate is fixedly installed on the top of the magnet. A distance detector is fixedly installed on the top of the workbench. The distance detector is used to detect the distance the magnet moves.

[0011] The adjustment assembly includes a stamping plate disposed below the worktable, the stamping plate being rotatable below the worktable, a stamping die being fixedly mounted on the surface of the stamping plate by bolts, several sets of stamping dies being arranged in a ring, an opening being provided inside the stamping die, an ejector rod being slidably connected to the inside of the stamping die through the opening, a slot being provided inside the stamping plate connecting to the opening, a push spring being fixedly mounted at the bottom of the slot, the push spring being fixedly connected to the bottom of the ejector rod, a stamping head being disposed above the worktable, the stamping head being movable up and down, an opening being provided at the top of the worktable, a control panel being fixedly mounted at the top of the worktable, the control panel being electrically connected to an electromagnet and a distance detector, and the depth of the stamping die being set from shallow to deep.

[0012] Furthermore, a fixed frame is fixedly installed on the top of the workbench, a stamping cylinder is fixedly installed on the bottom of the fixed frame, an installation plate is fixedly installed on the output end of the stamping cylinder, and the stamping head is fixedly connected to the installation plate by fixing bolts. The stamping head is located directly above the opening.

[0013] Furthermore, a connecting plate is fixedly installed between the bottoms of the worktable, and two sets of the connecting plates are symmetrically arranged. The stamping plate is rotatably connected between the connecting plates, and a servo motor is fixedly installed on the side of the connecting plate away from the stamping plate.

[0014] Furthermore, the stamping plate has an air outlet channel inside, and there are several sets of air outlet channels, with each end of the channel connected to a slot.

[0015] Furthermore, a piston plate is fixedly installed at the bottom of the ejector rod, the piston plate is slidably connected to the slot, and a through hole is opened inside the ejector rod and the piston plate, and a one-way valve is installed inside the through hole.

[0016] Furthermore, the top of the ejector rod is configured as an arc-shaped plate, and the surface of the ejector rod is provided with side holes.

[0017] Furthermore, the control panel is electrically connected to the servo motor.

[0018] Furthermore, a method for a drone fairing stamping device includes the following steps: S1, the operator first inputs the data of the standard material to be stamped into the control panel, and at the same time sets the magnetic force of the electromagnet. Then, the material is placed on the opening at the top of the workbench, and then the stamping cylinder is controlled by the control panel to stamp the material through the stamping head.

[0019] S2. After a single stamping is completed, the ejector rod pushes the stamped mold out by pushing the spring. The control panel controls the electromagnet to open, so that the magnet is repelled and the clamping plate moves relative to each other, thereby clamping the stamped mold.

[0020] S3. Due to the plasticity of the material during stamping, it will spring back to a certain height. The distance detector detects the magnet. Since the springback of the stamped material is different, the magnetic repulsive force on the magnet is the same. When the material is clamped and fixed, if the springback of the material is large, the magnet will be pushed back a certain distance by the material when the magnet drives the clamping plate to clamp it. At this time, the distance detector will detect the distance the magnet moves. The control panel calculates the springback of the material based on the distance the magnet moves. Based on the springback of the material, it calculates the number of stampings required for the material. Then the stamping plate rotates to the stamping die with a deeper die depth.

[0021] S4. Repeat this process until the stamping is complete, then the worker can manually remove it from between the clamping plates.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention, through its detection and adjustment components, enables segmented stamping of materials. Due to varying material springback after stamping, the magnet experiences the same magnetic repulsion. When clamping and fixing the material, if the springback is high, the magnet will be pushed back a certain distance by the material as it moves the clamping plate. A distance detector then measures the distance the magnet moves. The control panel calculates the material springback based on this distance and determines the required number of stamping passes. The stamping plate then rotates to a deeper die. This segmented stamping method improves the stamping effect. Adjusting the number of stamping passes based on springback increases the precision of the finished product, reducing the likelihood of defective products.

[0024] 2. This invention features an ejector rod. When the ejector rod moves downward, it drives the piston plate downward. As the piston plate moves, it pushes the gas inside the slot out through the air outlet channel and through hole into the slot connected to another set of stamping dies. The gas is then blown out through the side hole, thus blowing away impurities from the inner wall of the stamping die. When the stamping plate rotates, the gas tilts and pours out, thereby cleaning the inside of the stamping die and improving the quality of the material after stamping. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] A preferred embodiment of the present invention, a drone fairing stamping apparatus and method, will be described in detail below.

[0034] Example 1, as Figures 1-6 As shown, it includes: a workbench 1, with a detection component 2 and an adjustment component 3 respectively installed above and below the workbench 1;

[0035] The detection component 2 includes a sliding groove 201 formed on the top of the workbench 1. Two sets of sliding grooves 201 are symmetrically arranged. An electromagnet 202 is fixedly connected to one side of the sliding groove 201, and a magnet 203 is slidably connected to the side of the sliding groove 201 away from the electromagnet 202. A clamping plate 204 is fixedly installed on the top of the magnet 203. A distance detector 205 is fixedly installed on the top of the workbench 1. The distance detector 205 is used to detect the distance the magnet 203 moves.

[0036] The adjustment assembly 3 includes a stamping plate 301 located below the worktable 1. The stamping plate 301 can rotate below the worktable 1. A stamping die 302 is fixedly mounted on the surface of the stamping plate 301 by bolts. Several sets of stamping dies 302 are arranged in a ring. An opening 303 is opened inside the stamping die 302. An ejector rod 304 is slidably connected inside the stamping die 302 through the opening 303. A slot 305 connected to the opening 303 is opened inside the stamping plate 301. A push spring 306 is fixedly mounted at the bottom of the slot 305. The push spring 306 is fixedly connected to the bottom of the ejector rod 304. A stamping head 4 is located above the worktable 1. The stamping head 4 can move up and down. An opening 5 is opened at the top of the worktable 1. A control panel 6 is fixedly mounted at the top of the worktable 1. The control panel 6 is electrically connected to the electromagnet 202 and the distance detector 205.

[0037] The worker places the material to be stamped on the opening 5 at the top of the workbench 1. The stamping plate 301 rotates, so that the shallowest part of the stamping die 302 is located below the opening 5. When the stamping head 4 moves downward, it stamps the material into the stamping die 302. As the stamping head 4 continues to move the material downward, the material pushes the ejector rod 304 downward. At the same time, the bottom of the ejector rod 304 squeezes the push spring 306, causing it to contract due to elastic potential energy, and then the stamping head 4 stamps it. After stamping is completed, when the stamping head 4 moves upward, the push spring 306 pushes the ejector rod 304 upward due to elastic potential energy, causing the ejector rod 304 to eject the stamped material. At this time, the control panel 6 controls the electromagnet 202 to open. Under the action of magnetism, the electromagnet 202 pushes out the magnet 203. Since the shape of the stamped material is fixed, when the magnet 203 drives the clamping plate 204 to move relative to it, the clamping plate 204 clamps the formed material. While the material is fixed, the distance detector 205 detects the magnet 203. Due to the different springback of the stamped material, the magnet 203 experiences the same magnetic repulsive force. When the material is clamped and fixed, if the springback of the material is large, the magnet 203 will be pushed back a certain distance by the material when the clamping plate 204 clamps it. At this time, the distance detector 205 will detect the distance the magnet 203 moves. The control panel 6 calculates the springback of the material based on the distance the magnet 203 moves, and calculates the number of stampings required for the material based on the springback. Then, the stamping plate 301 rotates to the stamping die 302 with a deeper die depth. This segmented stamping method improves the stamping effect. At the same time, adjusting the number of stampings based on the springback can improve the accuracy of the finished product during stamping, thereby reducing the probability of defective products. After stamping is completed, the operator only needs to manually remove the stamped material from between the clamping plates 204.

[0038] Example 2, as Figure 1 As shown, it includes: a fixed frame 7 is fixedly installed on the top of the workbench 1, a stamping cylinder 8 is fixedly installed on the bottom of the fixed frame 7, an installation plate 9 is fixedly installed on the output end of the stamping cylinder 8, and a stamping head 4 is fixedly connected to the installation plate 9 by fixing bolts. The stamping head 4 is located directly above the through-hole 5.

[0039] The stamping cylinder 8 drives the stamping head 4 to move downward through the mounting plate 9, which can stamp the material. At the same time, the stamping head 4 can be replaced by fixing bolts, which is convenient for replacing different stamping heads 4 and replacing damaged stamping heads 4.

[0040] Example 3, as Figure 1 and Figure 6As shown, it includes: a connecting plate 10 is fixedly installed between the bottoms of the workbench 1, two sets of connecting plates 10 are symmetrically arranged, a stamping plate 301 is rotatably connected between the connecting plates 10, a servo motor 12 is fixedly installed on the side of the connecting plate 10 away from the stamping plate 301, and the control panel 6 is electrically connected to the servo motor 12.

[0041] The servo motor 12 can drive the stamping plate 301 to rotate, and the control panel 6 can control the servo motor 12 to rotate at a certain angle as needed.

[0042] Example 4, as Figures 3-5 As shown, it includes: an air outlet channel 13 is provided inside the stamping plate 301, and several sets of air outlet channels 13 are provided, with both ends connected to the slot 305 respectively; a piston plate 14 is fixedly installed at the bottom of the ejector rod 304, and the piston plate 14 is slidably connected to the slot 305; a through hole 15 is provided inside the ejector rod 304 and the piston plate 14, and a one-way valve 11 is provided inside the through hole 15; the top of the ejector rod 304 is set as an arc-shaped plate, and a side hole is provided on the surface of the ejector rod 304;

[0043] When the ejector rod 304 moves downward, it drives the piston plate 14 to move downward. As the piston plate 14 moves, it can push the gas inside the slot 305 out and push it into the slot 305 connected to another set of stamping dies 302 through the air outlet channel 13 and through hole 15. The gas is then blown out through the side hole, which blows the inner wall of the stamping die 302 and blows away the impurities inside. When the stamping plate 301 rotates, it tilts and pours out, which can clean the inside of the stamping die 302 and improve the quality of the material after stamping. When the ejector rod 304 moves upward, the piston plate 14 moves upward and can draw in the gas through the side hole and one-way valve 11. The piston plate 14 can then be reset.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
