Description

Technical Field

[0001] The present invention relates to a shearing device for producing unmanned aerial vehicles, and in particular to a cutting device and method for producing unmanned aerial vehicles. Background Art

[0002] The shearing machine with a disc cutter used in drones and their production is a mechanical device specially used for material cutting. It is usually used to cut plates or composite materials into predetermined sizes and shapes. This type of shearing machine is particularly useful in the drone manufacturing process because it can efficiently process a variety of materials, such as aluminum alloys, carbon fiber reinforced plastics (CFRP), etc., which are commonly used materials for drone structural parts. During the operation of the currently used disc knife cutting shearing machine, it is crucial to implement effective cooling and dust removal measures for the disc knife. However, traditional cooling methods mainly rely on directly injecting water into the disc knife or cutting area. This approach has two major disadvantages: first, it consumes a huge amount of water resources, which is not in line with the modern industrial concept of energy conservation and emission reduction; second, the direct injection of a large amount of water not only causes the debris generated by cutting to mix with water, but also easily causes these mixtures to splash everywhere, seriously polluting the working environment. What's more difficult is that even if dust removal equipment is introduced, it is difficult to achieve efficient dust removal in such a humid environment with widespread debris, which affects production efficiency and work safety.

[0003] Based on this, the present invention discloses a cutting device and method for UAV production. Summary of the invention

[0004] In order to solve the problem raised in the background technology, the present invention provides a cutting device for UAV production, which comprises a workbench, a disc knife cutting device body is arranged on the workbench, a disc knife is arranged below the disc knife cutting device body for cutting the UAV, and a water adding device is arranged on the disc knife cutting device body; Preferably, a mounting cylinder is further provided on the workbench near the position of the disc cutter, a dust suction pipe and an air blowing pipe are respectively connected to the two sides of the mounting cylinder, a second negative pressure fan is provided in the mounting cylinder at the connection place of the dust suction pipe, a water adding pipe is connected to the mounting cylinder above the second negative pressure fan, the water adding pipe is connected to the water adding device, the second negative pressure fan is used to disperse the water sprayed into the mounting cylinder by the water adding pipe, and generate positive pressure through the dust suction pipe to blow it in the opposite direction of the rotation direction of the disc cutter during cutting; A first negative pressure fan is also provided in the installation cylinder near the blowing pipe, which is used to generate negative pressure through the blowing pipe. The end of the blowing pipe away from the installation cylinder is opposite to the rotation direction of the disc knife during cutting. An ash storage bucket is connected to the lower part of the installation cylinder on the side of the first negative pressure fan away from the second negative pressure fan. A partition net is provided in the installation cylinder between the connection with the ash storage bucket, which is used to filter cutting impurities sucked in through the blowing pipe.

[0005] As a further improvement of the present technical solution, a rotating shaft is rotatably connected in the mounting cylinder, one end of the rotating shaft adjacent to the dust suction pipe is fixedly connected to the second negative pressure fan, the other end of the rotating shaft is fixedly connected to the first negative pressure fan, a bevel gear transmission assembly is provided on the rotating shaft, a driving motor is fixedly provided on the workbench, and the driving motor drives the rotating shaft to rotate through the bevel gear transmission assembly.

[0006] As a further improvement of the technical solution, an air inlet is provided on one side of the mounting tube adjacent to the blowing pipe, and the air inlet is connected to one end of the blowing pipe; An air blowing port is formed at one end of the installation tube away from the air blowing pipe, the air blowing port is connected to the dust suction pipe, and the radius of the dust suction pipe and the air blowing pipe is smaller than the radius of the installation tube; An ash inlet is provided at the bottom of the installation cylinder between the partition screen and the air inlet, and the ash inlet is communicated with the ash storage bucket.

[0007] As a further improvement of the technical solution, the end of the blowing pipe away from the mounting tube is connected to a dust hood, the dust hood is in a conical structure, and the radius of the dust hood away from the end of the blowing pipe is larger; One end of the dust suction pipe away from the mounting tube is connected with a blowing nozzle, the blowing nozzle is in a conical structure, and the radius of the blowing nozzle away from the end of the dust suction pipe is smaller.

[0008] Preferably, the blowing nozzle is arranged directly opposite the center of the dust hood.

[0009] As a further improvement of the technical solution, when the driving motor is started, the water adding device is started, and the nozzle of the water adding pipe is facing the second negative pressure fan.

[0010] Preferably, the second negative pressure fan and the first negative pressure fan are coaxially and symmetrically arranged.

[0011] The second object of the present invention is to provide a working method of a cutting device for UAV production, the specific steps of which are as follows: S1. When the disc knife cutting device body drives the disc knife to descend and the workpiece placed on the workbench is cut by the disc knife, the water adding device and the driving motor are started; S2, the driving motor starts to drive the rotating shaft to rotate through the bevel gear transmission assembly, and the first negative pressure fan generates negative pressure through the blowing pipe. The dust cover on the blowing pipe is facing the rotation direction of the disc knife when cutting, and the impurities and water mixture brought out by the disc knife when cutting are sucked into the blowing pipe, and then fall into the ash storage bucket after being filtered through the partition net; S3, the second negative pressure fan generates positive pressure through the dust suction pipe, the water adding device is started to spray water to the second negative pressure fan through the water adding pipe, the second negative pressure fan turns the water sprayed from the water adding pipe into mist, and sprays the water mist to the opposite direction of the rotation direction of the disc knife during cutting through the blowing nozzle on the dust suction pipe, so as to cool the disc knife and blow the impurities during cutting of the disc knife directly into the dust suction hood; S4. After the disc knife cutting is completed, the disc knife cutting device body rises, and the water adding device and the driving motor stop working.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the cutting device and method for producing unmanned aerial vehicles, a water adding device is coordinated with a blowing nozzle and a dust hood: when the water adding device is started, it sprays water mist onto the cutting area near the dust hood, and at the same time, the blowing nozzle blows out cold air entrained with water mist, which is beneficial to quickly reduce the temperature of the disc knife and the cutting point to avoid overheating. At the same time, the water mist form reduces the amount of water used, avoids the water waste caused by the traditional pouring method, and achieves the dual effects of efficient cooling and water saving.

[0013] 2. In the cutting device and method for drone production, a first negative pressure fan and a second negative pressure fan are symmetrically arranged and rotate synchronously: the first negative pressure fan generates negative pressure on one side of the blowing pipe to enhance the attraction of the dust hood to impurities, and the second negative pressure fan generates positive pressure on one side of the dust pipe to push water mist and air into the dust collection system. The two are symmetrically arranged and rotate synchronously, mutually enhancing the pressure in their respective pipes, thereby improving the dust collection and cooling efficiency, and achieving synergistic enhancement of dust collection and cooling.

[0014] 3. In the cutting device and method for drone production, the water sprayed from the water supply pipe is dispersed by the second negative pressure fan: the second negative pressure fan disperses the water sprayed from the water supply pipe into mist, which is conducive to the water mist to cover the cutting area more widely and improve the cooling effect. At the same time, the mist water will not soak impurities, avoiding the problem that impurities are difficult to be absorbed by the dust hood due to moisture, thereby achieving the improvement of the cooling effect and the optimization of impurity treatment.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The existing cooling device of the disc knife cutting device causes water waste by pouring, and is not conducive to subsequent dust prevention treatment.

[0019] To this end, the present invention provides a cutting device for UAV production, see Figure 1-Figure 3 As shown, it includes a workbench 1, on which a disc knife cutting device body 2 is arranged, below which a disc knife 4 is arranged for cutting the UAV workpiece, and on which a water adding device 3 is arranged.

[0020] Specifically, a mounting tube 5 is further provided on the workbench 1 near the position of the disc knife 4, and a dust suction pipe 6 and a blowing pipe 7 are respectively connected to the two sides of the mounting tube 5. An air inlet 20 is provided on the side of the mounting tube 5 near the blowing pipe 7, and the air inlet 20 is connected to one end of the blowing pipe 7. The end of the blowing pipe 7 away from the mounting tube 5 is connected to a dust hood 12, and the dust hood 12 has a conical structure, and the radius of the dust hood 12 away from the end of the blowing pipe 7 is larger; the end of the mounting tube 5 away from the blowing pipe 7 is provided with a blowing port 19, and the blowing port 19 is connected to the dust suction pipe 6. The end of the dust suction pipe 6 away from the mounting tube 5 is connected with a blowing nozzle 13, and the blowing nozzle 13 has a conical structure. The radius of the blowing nozzle 13 away from the end of the dust suction pipe 6 is smaller, and the blowing nozzle 13 is arranged directly opposite the center of the dust suction hood 12, so that the blowing force of the blowing nozzle 13 can assist the dust suction hood 12 in removing impurities at the cutting position, that is, the blowing nozzle 13 can blow the impurities directly into the dust suction hood 12; the radius of the dust suction pipe 6 and the blowing pipe 7 is smaller than the radius of the mounting tube 5, thereby increasing the pressure inside the dust suction pipe 6 and the blowing pipe 7.

[0021] Furthermore, a rotating shaft 14 is rotatably connected in the mounting tube 5, and a second negative pressure fan 17 is fixedly connected to one end of the rotating shaft 14 adjacent to the dust suction pipe 6, and a first negative pressure fan 15 is fixedly connected to the other end of the rotating shaft 14, and a bevel gear transmission assembly 18 is arranged on the rotating shaft 14. A driving motor 10 is fixedly arranged on the workbench 1, and the driving motor 10 drives the rotating shaft 14 to rotate through the bevel gear transmission assembly 18, and the second negative pressure fan 17 and the first negative pressure fan 15 are coaxial and symmetrically arranged, so that when the first negative pressure fan 15 and the second negative pressure fan 17 rotate synchronously, they can enhance each other's pressure in the adjacent pipes. That is to say, the positive pressure generated by the second negative pressure fan 17 relative to the dust suction pipe 6 will cause negative pressure for the first negative pressure fan 15 and the blowing pipe 7 located on the side away from the dust suction pipe 6, and the first negative pressure fan 15 generates negative pressure relative to the blowing pipe 7, so the negative pressure inside the blowing pipe 7 will be enhanced, which is more conducive to the dust removal of impurities at the cutting position by the dust suction hood 12; similarly, the negative pressure generated by the first negative pressure fan 15 relative to the blowing pipe 7 will cause positive pressure for the second negative pressure fan 17 and the dust suction pipe 6 located on the side of the first negative pressure fan 15 away from the blowing pipe 7, and the positive pressure inside the dust suction pipe 6 will be enhanced.

[0022] Furthermore, a water adding pipe 11 is connected to the installation cylinder 5 above the second negative pressure fan 17, and the water adding pipe 11 is connected to the water adding device 3. At the same time, when the driving motor 10 is started, the water adding device 3 is started, and the nozzle of the water adding pipe 11 is facing the second negative pressure fan 17. The second negative pressure fan 17 is used to break up the water sprayed into the installation cylinder 5 by the water adding pipe 11, and generate positive pressure through the dust suction pipe 6 to blow it in the opposite direction of the rotation direction of the disc knife 4 when cutting. The first negative pressure fan 15 located near the blowing pipe 7 is used to generate negative pressure through the blowing pipe 7, and the first negative pressure fan 15 located in the installation cylinder 5 is used to generate negative pressure through the blowing pipe 7. An ash storage bucket 9 is connected to the lower part of the side of the fan 15 away from the second negative pressure fan 17, and a partition net 16 is provided in the installation tube 5 between the connection point between the first negative pressure fan 15 and the ash storage bucket 9, which is used to filter the cutting impurities sucked in through the blowing pipe 7. In this way, when the negative pressure generated by the first negative pressure fan 15 sucks the impurities into the installation tube 5, the air filtered by the partition net 16 will enter the side of the first negative pressure fan 15 away from the blowing pipe 7, and then enter the dust suction pipe 6, helping to enhance the pressure in the dust suction pipe 6, and the impurities will fall into the ash storage bucket 9 through the ash inlet 21 for temporary storage.

[0023] Working principle: The workpiece is placed on the workbench 1, facing the bottom of the disc cutter 4. When the disc cutter cutting device body 2 drives the water adding device 3 to descend for cutting, the driving motor 10 and the water adding device 3 are started. When the water adding device 3 reaches the cutting position of the workpiece, Figure 4As shown, that is, the tangential direction of the water adding device 3 in the rotating direction is directly opposite to the lower center of the dust hood 12, and the tangential direction of the water adding device 3 in the rotating direction is directly opposite to the center of the blowing nozzle 13, so that when the disc knife 4 rotates and cuts, the impurities brought up by the friction will be directly blown obliquely into the dust hood 12, and the blowing nozzle 13 will carry water mist and cold wind to the tangential direction of the disc knife 4, so that the disc knife 4 and the cutting position can be cooled down, and the cutting position can be sprayed in the form of water mist, which is more conducive to cooling the disc knife 4 over a large area, and at the same time, it can avoid soaking the debris raised by the disc knife 4. Secondly, the blowing direction of the wind force can also assist in enhancing the debris at the cutting position to be sent into the dust hood 12; When the driving motor 10 is started, the rotating shaft 14 is driven to rotate through the bevel gear transmission assembly 18, so that the coaxially arranged first negative pressure fan 15 and the second negative pressure fan 17 will rotate synchronously, except that the first negative pressure fan 15 generates negative pressure relative to the blowing pipe 7, and the second negative pressure fan 17 generates positive pressure relative to the dust suction pipe 6, and the first negative pressure fan 15 and the second negative pressure fan 17 are coaxially arranged and have a symmetrical layout. In this way, when the first negative pressure fan 15 and the second negative pressure fan 17 rotate synchronously, they can enhance each other's pressure in the adjacent pipes. That is to say, the second negative pressure fan 17 generates a positive pressure relative to the dust suction pipe 6, then the first negative pressure fan 15 and the second negative pressure fan 17 located on the side away from the dust suction pipe 6 The blowing pipe 7 is under negative pressure, and the first negative pressure fan 15 generates negative pressure relative to the blowing pipe 7, so that the negative pressure inside the blowing pipe 7 will be enhanced, which is more conducive to the dust removal of impurities at the cutting position by the dust hood 12; similarly, the negative pressure generated by the first negative pressure fan 15 relative to the blowing pipe 7 is positive pressure for the second negative pressure fan 17 and the dust suction pipe 6 on the side of the first negative pressure fan 15 away from the blowing pipe 7, so the positive pressure inside the dust suction pipe 6 will be enhanced, and at the same time, the second negative pressure fan 17 can also break up the water sprayed from the water supply pipe 11 into mist, and then the water mist is sprayed onto the cutting position and the disc knife 4 through the blowing nozzle 13 through the joint action of the second negative pressure fan 17 and the first negative pressure fan 15; It is worth mentioning that the water sprayed from the water supply pipe 11 is dispersed by the second negative pressure fan 17. First, the dispersed water is in the form of water mist. Then, after being sprayed out through the blowing nozzle 13, it can expand the cooling range of the entire disc knife 4 and the cutting part compared with the traditional pouring cooling method. Second, the water mist is mixed with air and then blown out by strong wind force to further increase the cooling effect. Third, the water mist sprayed from the blowing nozzle 13 will not cause the impurities at the cutting part to be soaked in water and unable to be absorbed by the dust hood 12. In this way, after being sprayed in the form of mist, it can be quickly mixed with the impurity particles, reducing the speed at which the impurities are thrown out by the disc knife 4. At the same time, with the help of the blowing force of the blowing nozzle 13, it is more conducive to directly blowing the impurities into the dust hood 12. Fourth, it is sprayed in the form of water mist, which can reduce the amount of water sprayed by the water adding device 3 through the water adding pipe 11. That is to say, the water adding pipe 11 can even adopt a drip irrigation method, or minimize the flow rate to reduce the amount of water, so as to achieve the effect of spraying water mist from the blowing nozzle 13 and reduce the waste of water resources.

[0024] After the cutting is completed, the disc knife cutting device body 2 rises, and the water adding device 3 and the driving motor 10 stop working synchronously.

[0025] In summary, the problem that the existing cooling device wastes water resources by pouring and is not conducive to subsequent dust prevention treatment is effectively solved.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention.
