Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone manufacturing technology, and in particular to a drone blade stamping die. Background Technology
[0002] Drone blades, also known as drone propellers, are key components that generate lift and thrust for drones. Their performance directly affects the drone's flight performance and stability. They typically have a specific airfoil shape and generate lift and thrust through rotation. Parameters such as the shape, size, thickness, and torsion of the blades affect their performance. Generally speaking, the greater the length and width of the blades, the greater the lift and thrust generated, but this also increases the load on the motors and the drone's energy consumption.
[0003] Currently, one type of drone blade stamping die involves placing a metal sheet on a lower die and driving an upper die downwards using a stamping device. Under the action of a punch and a die, the sheet is stamped and formed, gradually deforming into the shape of a drone blade that meets the design requirements. However, the waste generated during the stamping process of traditional stamping dies often needs to be collected manually, which not only increases production costs but may also affect the automation level and efficiency of the production line. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a stamping die for drone blades, which aims to solve the problem of waste material flying around during the stamping process and being difficult to collect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a UAV blade stamping die, comprising a base plate, a lower template fixedly connected to the top of the base plate, a die fixedly connected to the top of the lower template, lower guide rods fixedly connected to the four corners of the top of the lower template, upper guide rods fixedly provided at the top of the four lower guide rods, an upper template fixedly connected to the top of the four upper guide rods, a punch fixedly connected to the bottom of the upper template, two collection boxes fixedly connected to the left side of the die, component slots opened at the top of the two collection boxes, motors fixedly connected to the bottom of the inner walls of the two component slots, lead screws fixedly provided at the output ends of the two motors, moving parts threadedly connected to the outer surfaces of the two lead screws, two first cylinders fixedly connected to the top of the two moving parts, connecting blocks fixedly connected to the top of adjacent first cylinders, a plate material provided at the top of the die, and a stacking assembly provided on the left side of the die.
[0006] Preferably, the stacking assembly includes a fixing block, which is fixedly connected to the die cavity. Two second cylinders are fixedly connected to the left side of the die cavity, and a push plate is fixedly connected to the left side of the two second cylinders. Two third cylinders are fixedly connected to the bottom of the base plate groove, and a receiving plate is fixedly connected to the top of the two third cylinders. Multiple rollers are provided on the top of the base plate groove.
[0007] Preferably, the upper guide rod and the lower guide rod are in close contact, and the upper guide rod moves up and down on the outer surface of the lower guide rod.
[0008] Preferably, the bottom of the connecting block and the top of the collecting box are tightly fitted with the left side of the plate, and the bottom right side of the plate is tightly fitted with the die.
[0009] Preferably, the bottom of the movable component is in close contact with the bottom of the component groove, and the bottom of the component groove is used to restrict the movable component.
[0010] Preferably, the outer surface of the connecting block is in close contact with the top of the component slot, and the connecting block can move up and down and back and forth in the component slot.
[0011] Preferably, the front and rear sides of the roller are rotatably connected between the front and rear sides of the groove in the base plate.
[0012] Preferably, the receiving plate fits tightly against the top of the groove in the base plate after the third cylinder is retracted.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, by setting collection boxes on both sides of the mold exit, after the plate is stamped by the punch and die, the waste on both sides is pushed to the top of the collection box. Then, the connecting block is pushed out from the component slot by the first cylinder and moved back and forth by the motor, thereby pulling the waste into the collection box. Then the connecting block returns to its original position, which solves the problem that the waste flies around during the stamping process and is not easy to collect.
[0015] 2. In this utility model, by setting a fixing block at the end of the mold, after the blade is stamped, it falls onto the receiving plate by the slope of the fixing block. The receiving plate slowly moves down as the blade falls. After the blade is stacked, the receiving plate also moves to be flush with the bottom plate. At this time, the push plate pushes to the left to push the stacked blade onto the roller. The receiving plate rises again to receive the blade, thus solving the problem of the blade being stacked messily after stamping. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a drone blade stamping die, comprising a base plate 1, a lower template 2 fixedly connected to the top of the base plate 1, a die 5 fixedly connected to the top of the lower template 2, lower guide rods 7 fixedly connected to the four corners of the top of the lower template 2, upper guide rods 6 provided on the top of the four lower guide rods 7, an upper template 3 fixedly connected to the top of the four upper guide rods 6, a punch 4 fixedly connected to the bottom of the upper template 3, two collection boxes 9 fixedly connected to the left side of the die 5, component slots 14 opened on the top of the two collection boxes 9, motors 10 fixedly connected to the bottom of the inner walls of the two component slots 14, lead screws 11 fixedly provided at the output ends of the two motors 10, moving parts 21 threadedly connected to the outer surfaces of the two lead screws 11, two first cylinders 12 fixedly connected to the top of the two moving parts 21, connecting blocks 13 fixedly connected to the top of the two adjacent first cylinders 12, a plate 8 provided on the top of the die 5, and stacking components provided on the left side of the die 5.
[0024] Specifically, when the stamping operation begins, the upper die 3 drives the punch 4 to press down. The plate 8 is stamped through the engagement between the punch 4 and the die 5. The plate 8 is stamped into blades and scrap. The blades are pushed forward by the plate 8 and squeezed out of the die 5, while the scrap is cut off from the plate 8 when the next piece is stamped. At this time, the connecting block 13, whose top is flush with the top of the collection box 9, is lifted by the first cylinder 12. After the engagement point is higher than the scrap, the connecting block 13 is driven by the motor 10 and the lead screw 11 to move outward, while pulling the scrap into the collection box 9. After the scrap enters the box, the connecting block 13 is driven by the first cylinder 12, the motor 10 and the lead screw 11 to descend and move inward to its original position for the next material hooking.
[0025] Reference Figure 2 and Figure 4 The stacking assembly includes a fixing block 19, which is fixedly connected to the die 5. Two second cylinders 15 are fixedly connected to the left side of the die 5. A push plate 16 is fixedly connected to the left side of the two second cylinders 15. Two third cylinders 17 are fixedly connected to the bottom of the groove of the base plate 1. A receiving plate 18 is fixedly connected to the top of the two third cylinders 17. Multiple rollers 20 are provided at the top of the groove of the base plate 1.
[0026] Specifically, after the sheet 8 is stamped into blades, as the material is continuously fed, the blades are pushed to the fixed block 19. Due to the slope of the fixed block 19, the blades slide down to the receiving plate 18 on the lower left of the fixed block 19. After receiving the blades, the receiving plate 18 slowly moves down under the action of the third cylinder 17, so that the continuously falling blades are stacked one by one until the receiving plate 18 is flush with the base plate 1. At this time, the second cylinder 15 starts to push the push plate 16 to the left, pushing the stacked blades onto the roller 20. Then the receiving plate 18 rises back to its original position and resumes receiving.
[0027] Reference Figure 1 and Figure 2 The upper guide rod 6 and the lower guide rod 7 are tightly fitted together, and the upper guide rod 6 moves up and down on the outer surface of the lower guide rod 7.
[0028] Specifically, the upper guide rods 6 and lower guide rods 7 at the four corners of the upper template 3 and lower template 2 are connected to each other and move in parallel to maintain the accuracy of the movement of the upper template 3 and lower template 2 during the stamping process, thus preventing stamping displacement.
[0029] Reference Figure 3 The bottom of connecting block 13 and the top of collecting box 9 are tightly fitted with the left side of plate 8, and the bottom right side of plate 8 is tightly fitted with the cavity 5.
[0030] Specifically, after the sheet metal 8 is stamped by the die 5 and the punch 4, the waste part is hooked by the connecting block 13 and collected.
[0031] Reference Figure 2 The bottom of the movable part 21 fits tightly against the bottom of the component groove 14, and the bottom of the component groove 14 is used to restrict the movable part 21.
[0032] Specifically, when the motor 10 is started, the lead screw 11 rotates, and the moving part 21, which is threadedly connected to it, can only move in parallel and will not flip due to the restriction at the bottom of the component slot 14.
[0033] Reference Figure 3 The outer surface of the connecting block 13 fits tightly against the top of the component slot 14, and the connecting block 13 can move up and down and back and forth in the component slot 14.
[0034] Specifically, the connecting block 13 moves up and down in the component slot 14 via the first cylinder 12, and moves back and forth on the lead screw 11 via the moving part 21, thus moving back and forth in the component slot 14.
[0035] Reference Figure 4 The front and rear sides of the roller 20 are rotatably connected between the front and rear sides of the groove in the base plate 1.
[0036] Specifically, after the stack of blades is pushed onto the roller 20, the roller 20 is easy to push, which prevents the pusher plate 16 from getting stuck when pushing the stack of blades.
[0037] Reference Figure 4 After the third cylinder 17 is retracted, the receiving plate 18 fits tightly against the top of the groove in the base plate 1.
[0038] Specifically, after the receiving plate 18 receives a certain amount of blades, its position drops to be flush with the bottom plate 1. After the top blades are pushed out by the push plate 16, the receiving plate 18 rises again.
[0039] Working principle: When the stamping operation begins, the upper die 3 drives the punch 4 to press down. Through the engagement between the punch 4 and the die 5, the sheet metal 8 is stamped and the sheet metal 8 is stamped into blades and scrap. The blades are pushed forward by the sheet metal 8 and squeezed out of the die 5, while the scrap is cut off from the sheet metal 8 when the next piece is stamped. At this time, the connecting block 13, whose top is flush with the top of the collection box 9, is driven to rise by the first cylinder 12. After the engagement point is higher than the scrap, the connecting block 13 is driven to move outward by the motor 10 and the lead screw 11, while pulling the scrap into the collection box 9. After the scrap enters the box, the connecting block 13 is driven by the first cylinder 12, the motor 10 and the lead screw 11 to descend and move inward to its original position for the next material hooking.
[0040] After the sheet 8 is stamped into blades, as the material is continuously fed, the blades are pushed to the fixed block 19. Due to the slope of the fixed block 19, the blades slide down to the receiving plate 18 on the lower left of the fixed block 19. After receiving the blades, the receiving plate 18 slowly moves down under the action of the third cylinder 17, so that the continuously falling blades are stacked one by one until the receiving plate 18 is flush with the base plate 1. At this time, the second cylinder 15 starts to push the push plate 16 to the left, pushing the stacked blades onto the roller 20. Then the receiving plate 18 rises back to its original position and resumes receiving.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
