Description

Technical Field

[0001] This invention relates to the field of automotive sheet metal technology, specifically to a stamping and trimming mechanism for new energy vehicle body sheet metal. Background Technology

[0002] New energy vehicles have the advantages of energy saving, environmental protection, and affordability. However, in the production process of new energy vehicles, sheet metal stamping and trimming are required to remove excess material and prepare for subsequent processes. During this process, a stamping and trimming mechanism is needed, and material debris is generated. The accumulation of this debris increases the workload of subsequent cleaning. To overcome this defect, prior art 1 (Chinese patent application No. 202411035164.8, application date 2024-07-31) provides a material cutting mechanism with anti-debris... A sheet metal stamping press with a blocking structure has the following features: During operation, the first notch moves to increase the distance between it and the second notch, preventing material blockage during stamping. Secondly, when the cleaning rod rotates to the side of the scrap material, it squeezes the scrap into the through-groove, allowing it to fall into a collection box for collection, thus improving the material feeding function of the sheet metal stamping press. Finally, the nozzle cleans debris or residue from the upper surface of the lower platen, preventing positional deviation during processing and improving the processing quality of the stamping press. (Previous technology 2 (application number 202122543438)). 2. A Chinese patent application filed on May 20, 2024, describes a sheet metal mold with a cleaning function. During use, an air pump uses suction to blow air into the stamping mold. Since debris is left after processing in the stamping mold, if not cleaned, it will affect the accuracy of subsequent processing. The debris is blown into the air outlet by the air pump, thus cleaning up the remaining debris and increasing processing accuracy. Prior art 3 (Chinese patent application number 201910630757.1, filed on July 12, 2019) describes a single-punch multi-die sheet metal stamping... In the automated processing line, when the conveying mechanism carries the profile into the top of the support mechanism, the compression mechanism drives the top of the stamping mechanism downwards, causing the stamping mechanism to process the profile into a workpiece. The processed workpiece and the profile enter the interior of the pushing mechanism together. The pushing mechanism rotates, driving the profile to move, and the pushing mechanism also drives the guiding mechanism to rotate. The rotation of the guiding mechanism indirectly pushes the workpiece, reducing the labor intensity of workers and improving the processing efficiency of the workpiece. A collecting mechanism is installed at the top of the support mechanism and is located between the pushing mechanisms. The stamped debris on the profile falls into the interior of the collecting mechanism, making it convenient to remove debris from the sheet metal parts.

[0003] During the cutting process, a large amount of waste gas is generated, which will affect the working environment. The device in the above application does not have a structure for rapid waste gas treatment during use, which will have a negative impact on the health of the workers and is not conducive to their long-term work. Summary of the Invention

[0007] Preferably, the swing mechanism includes a second gear fixedly connected to the surface of the rotating shaft, and the rotating shaft is fixedly connected to the flue gas absorption plate. The flue gas absorption plate is connected to an external flue gas treatment device through an external hose. A connecting shaft is rotatably provided inside the fixed frame, and an auxiliary rod is fixedly connected to the surface of the connecting shaft. A sleeve is slidably provided on the surface of the auxiliary rod.

[0008] Preferably, a push frame is fixedly connected to the surface of the working shaft, a column is fixedly connected to the upper surface of the sleeve, and the column is slidably disposed inside the push frame. The push frame is perpendicular to the working shaft. A first gear is fixedly connected to both ends of the connecting shaft, and the first gear corresponds one-to-one with the second gear, and the first gear and the second gear are meshed.

[0009] Preferably, the lifting mechanism includes a fixed block fixedly connected to the surface of the movable column, a circular plate fixedly connected to the end of the rotating shaft, a protrusion fixedly connected to the surface of the circular plate, and a connecting rod sleeved on the surface of the protrusion and the surface of the fixed block, wherein the end of the protrusion and the end of the fixed block are both protruding.

[0010] Preferably, the movable columns are symmetrically distributed on both sides of the collection frame, and the movable columns penetrate the interior of the working plate, with the surface of the movable columns fitting against the inner wall of the working plate.

[0011] Preferably, an auxiliary plate is fixedly connected to the side of the collection frame, and the top view of the auxiliary plate is an inverted "U" shape. The auxiliary plate and the movable column are connected through the plate. The opening length at the upper end of the collection frame is greater than the opening length at the lower end of the collection frame.

[0012] Preferably, a transition rod is rotatably provided at the end of the auxiliary plate, a lower connecting plate is fixedly connected to the lower surface of the working plate, and a push block is fixedly connected to the inner wall of the lower connecting plate.

[0013] Preferably, the upper and lower sides of the pusher are inclined, and the pushers are evenly distributed on the inner wall of the lower plate.

[0014] Preferably, a connecting spring that provides elastic reset is fixedly connected to the inner wall of the auxiliary plate, and the other side of the connecting spring is fixedly connected to the surface of the movable column. A damping rod is fixedly connected to the surface of the movable column, and the output end of the damping rod is fixedly connected to the inner wall of the auxiliary plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Adopting a novel structural design, the oscillating flue gas absorption plate can absorb the exhaust gas generated during the trimming process from multiple angles, optimizing the working environment. Simultaneously, the debris generated during the trimming process falls into the collection frame. During the oscillation of the flue gas absorption plate, the collection frame is moved vertically by the movable column, and simultaneously, the collection frame is moved reciprocating linearly within the movable column by the auxiliary plate. This allows the collection frame to expedite the discharge of debris, resulting in high work efficiency. The specific details are as follows:

[0016] (1) When the new energy vehicle body sheet metal stamping and trimming mechanism is working, the working plate completes the stamping work through the stamping die group, and then completes the trimming work through the trimming component of the robotic arm. During the working process, the motor is started, and the motor drives the working shaft to rotate, which in turn pushes the frame to rotate. At this time, the connecting shaft and the first gear are in a swinging state, and the connecting shaft, the first gear and the rotating shaft drive the flue gas absorption plate to reciprocate. At this time, the flue gas absorption plate can absorb exhaust gas over a wider range, which improves the air quality in the working environment.

[0017] (2) When the rotating shaft rotates, the rotating shaft drives the circular plate to rotate synchronously. At this time, the circular plate drives the movable column to move through the protrusion, connecting rod and fixed block. The surface of the movable column is in contact with the inner wall of the working plate, so the movable column makes reciprocating linear motion in the vertical direction. When the movable column moves, it will drive the collection frame to move synchronously. At this time, the debris inside the collection frame can be shaken off more quickly, which improves the work efficiency.

[0018] Furthermore, both the ends of the protrusions and the fixed blocks are protruding, which prevents the connecting rod from falling off and ensures the stability of the moving column, connecting rod, and collection frame during operation.

[0019] (3) When the moving column drives the auxiliary plate and the collection frame to move in the vertical direction, the auxiliary plate is equipped with a transition rod at the end of the auxiliary plate. It will be pushed intermittently by the push block on the surface of the lower plate. At this time, the auxiliary plate drives the collection frame to move in the horizontal direction under the action of the thrust and the elastic force. At this time, the collection frame moves not only in the vertical direction but also in the horizontal direction, which can discharge the debris more quickly.

[0020] Furthermore, during the movement of the auxiliary plate, the damping rods make the movement of the auxiliary plate more stable, while the push blocks are evenly distributed on the surface of the lower plate, which increases the working frequency of the auxiliary plate, so that the collection frame can better discharge debris.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides the following technical solution: a stamping and trimming mechanism for sheet metal body of new energy vehicles.

[0033] Example 1: The reciprocating oscillating flue gas absorption plate 19 allows for the absorption of flue gas over a wide range, such as... Figures 1-5 As shown, the system includes a work plate 1, a stamping die set 2 on the upper surface of the work plate 1, a trimming die 3 on the upper surface of the work plate 1, and a robotic arm 4 on the upper surface of the work plate 1; a vertical plate 5 is bolted to the upper surface of the work plate 1, and an outer plate 12 is fixedly connected to the surface of the vertical plate 5; a rotating shaft 13 is rotatably mounted inside the outer plate 12, and the rotating shaft 13 is connected to a flue gas absorption plate 19 through a swing mechanism; a horizontal plate 8 is bolted to the upper end of the right side of the vertical plate 5, and a motor 9 is bolted to the surface of the horizontal plate 8; a working shaft 20 is fixedly connected to the output end of the motor 9; and a fixing frame 10 is fixedly connected to the surface of the vertical plate 5.

[0034] The swing mechanism includes a second gear 21 fixedly connected to the surface of the rotating shaft 13, and the rotating shaft 13 is fixedly connected to the flue gas absorption plate 19. The flue gas absorption plate 19 is connected to an external flue gas treatment device through an external hose. A connecting shaft 11 is rotatably arranged inside the fixed frame 10, and an auxiliary rod 15 is fixedly connected to the surface of the connecting shaft 11. A sleeve 16 is slidably arranged on the surface of the auxiliary rod 15. A push frame 14 is fixedly connected to the surface of the working shaft 20. A column 17 is fixedly connected to the upper surface of the sleeve 16. The column 17 is slidably arranged inside the push frame 14. The push frame 14 is perpendicular to the working shaft 20. A first gear 18 is fixedly connected to both ends of the connecting shaft 11. The first gear 18 and the second gear 21 correspond one-to-one and are meshed.

[0035] During operation, the work plate 1 completes the stamping work through the stamping die group 2, and then completes the edge cutting work through the edge cutting assembly and edge cutting die 3 of the robotic arm 4. During the operation, the motor 9 on the surface of the horizontal plate 8 is started. At this time, the motor 9 drives the working shaft 20 to rotate, which in turn pushes the frame 14 to rotate. When the frame 14 rotates, it pushes the column 17 and the sleeve 16 to slide on the surface of the auxiliary rod 15. At this time, the auxiliary rod 15 drives the connecting shaft 11 to reciprocate inside the fixed frame 10. Then, the connecting shaft 11 is in a swinging state through the first gear 18. When the first gear 18 rotates, it drives the rotating shaft 13 to swing inside the outer plate 12 through the second gear 21. At this time, the rotating shaft 13 drives the flue gas absorption plate 19 to reciprocate. At this time, the flue gas absorption plate 19 can absorb more exhaust gas, improving the air quality in the working environment.

[0036] Example 2: Unlike Example 1, the movable column 25, fixed block 26, and connecting rod 27 allow the collection frame 7 to reciprocate linearly in the vertical direction, enabling the collection frame 7 to quickly discharge debris. Figure 1 , Figure 6 and Figure 9 As shown, a movable column 25 is slidably arranged inside the working plate 1, and the movable column 25 is connected to the collection frame 7 through a lifting mechanism. The lifting mechanism includes a fixed block 26 fixedly connected to the surface of the movable column 25, a circular plate 22 fixedly connected to the end of the rotating shaft 13, and a protrusion 23 fixedly connected to the surface of the circular plate 22. A connecting rod 27 is sleeved and connected to both the surface of the protrusion 23 and the surface of the fixed block 26. The ends of the protrusion 23 and the fixed block 26 are both protruding. The movable column 25 is symmetrically distributed on both sides of the collection frame 7, and the movable column 25 penetrates the interior of the working plate 1. The surface of the movable column 25 is in contact with the inner wall of the working plate 1.

[0037] An auxiliary plate 24 is fixedly connected to the side of the collection frame 7. The top view of the auxiliary plate 24 is an inverted "U" shape. The auxiliary plate 24 and the movable column 25 are connected through and movable. The opening length at the upper end of the collection frame 7 is greater than the opening length at the lower end of the collection frame 7.

[0038] When the rotating shaft 13 rotates, it drives the circular plate 22 to rotate synchronously. At this time, the circular plate 22 drives the movable column 25 to move through the protrusion 23, the connecting rod 27 and the fixed block 26. The surface of the movable column 25 is in contact with the inner wall of the working plate 1, so the movable column 25 makes a reciprocating linear motion in the vertical direction. When the movable column 25 moves, it will drive the collection frame 7 to move synchronously. At this time, the collection frame 7 is in a moving state, so the debris inside the collection frame 7 can be shaken off more quickly, improving work efficiency. The ends of the protrusion 23 and the fixed block 26 are both protruding, so the connecting rod 27 will not fall off, ensuring the stability of the movable column 25, the connecting rod 27 and the collection frame 7.

[0039] Example 3: Unlike Example 2, the pusher 31, transition rod 30, and connecting spring 28 allow the auxiliary plate 24 and collecting frame 7 to reciprocate linearly in the horizontal direction, thus enabling the collecting frame 7 to discharge materials more quickly. Figures 6-8 As shown, a transition rod 30 is rotatably provided at the end of the auxiliary plate 24, a lower connecting plate 6 is fixedly connected to the lower surface of the working plate 1, and a push block 31 is fixedly connected to the inner wall of the lower connecting plate 6. The upper and lower sides of the push block 31 are inclined, and the push blocks 31 are evenly distributed on the inner wall of the lower connecting plate 6.

[0040] A connecting spring 28, which plays an elastic reset role, is fixedly connected to the inner wall of the auxiliary plate 24, and the other side of the connecting spring 28 is fixedly connected to the surface of the movable column 25. A damping rod 29 is fixedly connected to the surface of the movable column 25, and the output end of the damping rod 29 is fixedly connected to the inner wall of the auxiliary plate 24.

[0041] When the movable column 25 drives the auxiliary plate 24 and the collection frame 7 to move vertically, the auxiliary plate 24 is equipped with a transition rod 30 at its end, which is intermittently pushed by the push block 31 on the surface of the lower plate 6. When the auxiliary plate 24 is pushed, it slides inside the movable column 25 and simultaneously compresses the connecting spring 28. When the auxiliary plate 24 is not pushed, it returns to its original position under the action of the connecting spring 28. That is, the auxiliary plate 24 drives the collection frame 7 to move horizontally. At this time, the collection frame 7 moves not only vertically but also horizontally, which can discharge debris more quickly. During the movement of the auxiliary plate 24, the damping rod 29 makes the movement of the auxiliary plate 24 more stable, and the push blocks 31 are evenly distributed on the surface of the lower plate 6, which increases the working frequency of the auxiliary plate 24, so that the collection frame 7 can discharge debris better.

[0042] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although the present invention 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 invention should be included within the protection scope of the present invention.
