Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle production, in particular to a stamping die for producing an unmanned aerial vehicle shell. Background Technique

[0002] An unmanned aerial vehicle, also known as a drone, is an unpiloted aircraft that is controlled by radio remote control equipment or a self - contained program control device. It can complete complex aerial flight tasks and various payload tasks without a pilot. The shell of an unmanned aerial vehicle is the external protection structure, which mainly protects internal components of the unmanned aerial vehicle, such as batteries, motors, flight control systems, etc. from the external environment. The design of the shell not only needs to consider the protection performance, but also needs to take into account lightweight, durability, and aerodynamic characteristics to ensure the flight efficiency and stability of the unmanned aerial vehicle. During the production process of the unmanned aerial vehicle shell, using a stamping die can quickly and accurately produce an unmanned aerial vehicle shell that meets the design requirements, improve production efficiency, reduce costs, and ensure the accuracy and consistency of the shell.

[0003] A Chinese patent with the publication number CN221581708U discloses a stamping die for forming unmanned aerial vehicle blades, which includes an upper template, a lower template, and a telescopic guide member connected between the upper template and the lower template. The upper template and the lower template are symmetrically arranged up and down. Upper die pads and lower die pads are respectively fixed at the relative positions of the upper template and the lower template. A punch and a die are respectively fixed at the relative positions of the upper die pad and the lower die pad. The punch and the die cooperate to form a stamping cavity for forming unmanned aerial vehicle blades. There is an open space around the mating position of the upper die and the lower die. A limiting component is arranged between the upper template and the lower template. The limiting component includes an upper limiting block fixed on the upper die pad and a lower limiting block fixed on the lower die pad, and the height of the upper limiting block is equal to the height of the lower limiting block.

[0004] Although the above - mentioned scheme has the advantages of high forming accuracy, simple structure, and low production cost, there are various types of unmanned aerial vehicle shells. The lower die is the part that directly contacts and forms the material during the stamping process. The structure of the lower die of this stamping die is fixed, and replacing the lower die requires a cumbersome disassembly and installation process, which increases the operation difficulty and is inconvenient to use. Therefore, it does not meet the existing requirements. For this reason, we propose a stamping die for producing an unmanned aerial vehicle shell. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stamping die for producing an unmanned aerial vehicle shell, so as to solve the problem that the replacement of the lower die during stamping of the stamping die is relatively cumbersome, resulting in inconvenient use as mentioned in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solution: A stamping die for the production of a drone housing, including a base, a clamping groove is opened at the upper end of the base, a lower die is arranged inside the clamping groove, a top cover is arranged below the base, and the top cover and the base are connected by four connecting rods;

[0007] It further includes transmission cavities, which are opened on both sides inside the base. A double-threaded transmission rod is rotatably arranged on one side inside each transmission cavity. The front and rear sides of the outside of the double-threaded transmission rod are both threadedly connected with moving blocks. One end of each moving block extends to the outside of the transmission cavity, and the moving blocks are all slidably matched with the transmission cavity. A limiting block is welded on the inner side of one end of each moving block located outside the transmission cavity;

[0008] It further includes guide grooves, which are opened on both sides inside the clamping groove, and four are equidistantly distributed on each side.

[0009] Preferably, motors are installed on both sides of the rear end of the base, and the output ends of the motors are in transmission connection with the double-threaded transmission rods through couplings.

[0010] Preferably, guide rods are welded on one side inside each transmission cavity. The guide rods all penetrate through the moving blocks, and the guide rods are all slidably matched with the moving blocks.

[0011] Preferably, limiting grooves are opened on both sides of the front and rear ends of the lower die, and the limiting grooves are all adapted to the limiting blocks.

[0012] Preferably, a hydraulic cylinder is installed on the upper end of the top cover. The output end of the hydraulic cylinder is provided with an upper die. Sliding blocks are welded on both sides of the upper die. The sliding blocks are all penetrated by the connecting rods, and the sliding blocks are all slidably matched with the connecting rods.

[0013] Preferably, buffer springs are sleeved on the lower sides of the outside of the connecting rods. One end of each buffer spring is connected to the sliding block, and the other end of each buffer spring is connected to the base.

[0014] Preferably, four guide blocks are welded on both sides of the lower die at equal intervals, and the guide blocks are all slidably matched with the guide grooves.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In the present utility model, drive chambers are provided on both sides inside the base. When it is necessary to replace the lower die, the motor can be started. The motor will drive the double-threaded drive rod to rotate synchronously. The double-threaded drive rod will drive the two moving blocks to perform opposite horizontal linear movements. The movement of the moving blocks will drive the limit blocks to slide out of the limit grooves, thereby releasing the clamping and fixing of the lower die. The operator can move the lower die upward to take it out of the clamping groove. The operator only needs to simply start the motor to easily complete the release and replacement of the lower die, significantly improving the flexibility and operation efficiency of the production line.

[0017] 2. In the present utility model, a buffer spring is sleeved on the lower side of the outside of the connecting rod. When the upper die moves downward for stamping, it will drive the slider to slide synchronously on the connecting rod. When the slider moves downward, it will compress the buffer spring. The compression deformation of the buffer spring can slow down the direct impact of the upper die on the lower die, making the stamping action smoother and softer, avoiding problems such as die damage or workpiece deformation caused by the instantaneous huge impact force. At the same time, the elasticity of the buffer spring can also help the slider and the upper die to quickly reset after the stamping is completed, preparing for the next stamping operation.

[0018] 3. In the present utility model, four equally spaced guiding grooves are provided on both sides of the clamping groove, and four equally spaced guiding blocks are welded on both sides of the lower die. The operator only needs to align the guiding blocks of the lower die with the guiding grooves of the clamping groove and then move downward to achieve quick installation. This sliding installation method greatly simplifies the replacement process, reduces the operation steps and the required time, improves the work efficiency, and ensures that the lower die can be accurately clamped into the clamping groove during replacement, realizing precise positioning and installation.

Detailed implementation manners

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a stamping die for the production of a drone housing, including a base 1, a clamping groove 9 is opened at the upper end of the base 1, a lower die 4 is arranged inside the clamping groove 9, a top cover 2 is arranged below the base 1, and the top cover 2 and the base 1 are connected by four connecting rods 6;

[0026] It further includes a transmission cavity 12, which is opened on both sides inside the base 1. A double-threaded transmission rod 13 is rotatably arranged on one side inside the transmission cavity 12. The front and rear sides of the outside of the double-threaded transmission rod 13 are both threadedly connected with a moving block 15. One end of the moving block 15 extends to the outside of the transmission cavity 12, and the moving block 15 is slidably matched with the transmission cavity 12. A limiting block 17 is welded to the inner side of one end of the moving block 15 located outside the transmission cavity 12;

[0027] It further includes a guiding groove 10, which is opened on both sides inside the clamping groove 9, and four guiding grooves are evenly distributed on each side.

[0028] During use, the hydraulic cylinder 3 is started, and its output end pushes the upper die 5 to move smoothly downward along the connecting rod 6. During this period, the slider 7 slides down synchronously and compresses the buffer spring 8, effectively buffering the direct impact of the upper die 5 on the lower die 4, ensuring that the stamping process is stable and gentle, and protecting the die and the workpiece. When it is necessary to replace the lower die 4 for different drone housings, the motor 14 drives the two moving blocks 15 to move in opposite directions on the guiding rod 16 through the double-threaded transmission rod 13, so that the limiting block 17 is disengaged from the limiting groove 18, thereby conveniently releasing the fixation of the lower die 4. When replacing, the new lower die 4 is aligned with the guiding groove 10 of the clamping groove 9 through the guiding block 11 and easily snapped in, realizing rapid and accurate positioning and installation. The overall process is simple and efficient, facilitating daily operation and maintenance.

[0029] Please refer to Figure 1 and Figure 2 , motors 14 are installed on both sides of the rear end of the base 1. The output end of the motor 14 is in transmission connection with the double-threaded transmission rod 13 through a coupling. The power of the motor 14 can be efficiently and stably transmitted to the double-threaded transmission rod 13, thereby realizing the synchronous and reverse movement of the two moving blocks 15, providing power support for the rapid replacement of the lower die 4;

[0030] Please refer to Figure 2 , guide rods 16 are welded on one side inside the transmission cavity 12. The guide rods 16 all penetrate through the moving blocks 15, and the guide rods 16 are all in sliding fit with the moving blocks 15. The guide rods 16 provide precise guidance for the linear movement of the moving blocks 15, preventing them from shifting or wobbling during movement, ensuring that the moving blocks 15 can accurately and stably drive the limit blocks 17 to perform limiting or releasing limiting operations, and improving the stability and reliability of the equipment;

[0031] Please refer to Figure 4 , limiting grooves 18 are provided on both sides of the front and rear ends of the lower die 4, and the limiting grooves 18 are all adapted to the limit blocks 17. Through the close fit of the limiting grooves 18 and the limit blocks 17, stable limiting of the lower die 4 is achieved, preventing the lower die 4 from moving or shifting during the stamping process, ensuring the accuracy and safety of stamping, and at the same time providing convenience for the rapid replacement of the lower die 4. Simply releasing the limit of the limit block 17 can easily remove or install the lower die 4;

[0032] Please refer to Figure 1 and Figure 3 , a hydraulic cylinder 3 is installed at the upper end of the top cover 2. The output end of the hydraulic cylinder 3 is provided with an upper die 5. Sliders 7 are welded on both sides of the upper die 5. The sliders 7 are all penetrated by the connecting rods 6, and the sliders 7 are all in sliding fit with the connecting rods 6. Driven by the hydraulic cylinder 3, the upper die 5 can move down smoothly and accurately along the connecting rods 6 for stamping operations. The sliding fit of the sliders 7 and the connecting rods 6 ensures the stability and guiding property of the upper die 5 during movement, reduces impact and vibration, and protects the die and the workpiece;

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 , buffer springs 8 are sleeved on the lower sides of the outer parts of the connecting rods 6. One ends of the buffer springs 8 are all connected to the sliders 7, and the other ends of the buffer springs 8 are all connected to the base 1. The buffer springs 8 can effectively absorb the impact force and vibration generated during the downward movement of the upper die 5, slow down the direct impact on the lower die 4, protect the die from damage, and at the same time make the stamping action smoother and softer, improving the processing quality and production efficiency of the product;

[0034] Please refer to Figure 2 and Figure 4 , four equally spaced guide blocks 11 are welded on both sides of the lower die 4, and the guide blocks 11 are all in sliding fit with the guide grooves 10. Through the close fit of the guide blocks 11 and the guide grooves 10, precise guidance and support are provided for the installation and positioning of the lower die 4, ensuring that the lower die 4 can be accurately inserted into the card slot 9 during installation, achieving precise positioning and installation, and at the same time improving the stability and safety of the lower die 4 during the stamping process.

[0035] Working principle: When in use, start the hydraulic cylinder 3. The output end of the hydraulic cylinder 3 will drive the upper die 5 to move downward. The upper die 5 will drive the slider 7 to move downward synchronously on the connecting rod 6. When the slider 7 moves downward, it will compress the buffer spring 8. The compression deformation of the buffer spring 8 can slow down the direct impact of the upper die 5 on the lower die 4, making the stamping action smoother and softer, and avoiding problems such as die damage or workpiece deformation caused by the instantaneous huge impact force. The downward movement of the upper die 5 can cooperate with the lower die 4 to achieve the stamping production of the drone shell. When it is necessary to stamp different drone shells, the motor 14 can be started. The motor 14 will drive the double-threaded transmission rod 13 to rotate synchronously through the coupling. The double-threaded transmission rod 13 will drive the two moving blocks 15 to rotate synchronously. Since the moving blocks 15 are all slidably matched with the guide rod 16, the moving blocks 15 will all be axially limited. The rotation of the two moving blocks 15 will be converted into horizontal linear movements in opposite or opposite directions, causing the two moving blocks 15 to move in opposite directions. The moving block 15 will drive the limiting block 17 to move out of the inside of the limiting groove 18, so that the limiting and fixing of the lower die 4 can be quickly released. The lower die 4 can be removed from the inside of the card slot 9 for replacement. When the new lower die 4 is inserted into the card slot 9, align the guide block 11 with the guide groove 10 of the card slot 9, and then move downward to achieve quick installation, ensuring that the lower die 4 can be accurately inserted into the card slot 9 during replacement, realizing precise positioning and installation. The overall replacement process of the lower die 4 is simple and convenient, facilitating daily use.
