Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts manufacturing technology, and in particular to a high-efficiency material feeding mechanism for a precision stamping production line. Background Technology

[0002] Stamping production lines are commonly used for the mass production of metal stamping parts, especially in the production of electric vehicle components. Most components are formed by stamping blanked metal sheets, such as the left and right mounting plates for electric vehicle swingarms. In actual production, the stamping process is usually completed manually by workers, which is labor-intensive and poses high safety risks. Furthermore, the high degree of fit between the blanks obtained from high-precision stamping and the holes left on the sheet metal can make it difficult to separate them quickly during blanking, affecting the efficiency of blanking. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a high-efficiency feeding mechanism for a precision stamping production line, which can quickly separate the precision stamped sheet from the cut sheet, thereby achieving efficient feeding.

[0004] Technical solution: To achieve the above objectives, this utility model provides a high-efficiency unloading mechanism for a precision stamping production line, including a sheet-picking component capable of picking up the stamping sheet. The sheet-picking component is connected to a lifting drive device, which can press down the sheet when it descends and lift the sheet when it rises.

[0005] A hammer is provided on one side of the sheet-retrieving component and connected to an up-and-down swinging device, which can drive the hammer to strike the sheet when the sheet-retrieving component presses down on the sheet.

[0006] Furthermore, the up-and-down swinging device includes a swing rod, the middle of which cooperates with a hinge seat, and a long rod segment and a short rod segment on both sides of the hinge. The end of the long rod segment is fixedly connected to the hammer, and the end of the short rod segment cooperates with a pressing and releasing device, which can periodically apply downward pressure to the short rod segment.

[0007] Furthermore, the piece-taking component is fixedly connected to one end of the cantilever, and the other end of the cantilever is fixedly connected to the rotating shaft of the rotating device, so that the cantilever can rotate horizontally and drive the piece-taking component to correspond to one of the punching position and the stacking position. The rotating device is fixedly connected to the piston rod end of the longitudinal drive cylinder.

[0008] Furthermore, the piece-retrieving component is a magnetic block.

[0009] Furthermore, the hinge seat and pressing device are both fixedly connected to the table surface of the rotating table, and can rotate to drive the hammer to correspond to one of the punching position and the stacking position. When the hammer corresponds to the stacking position, it can be placed on top of the material stack under its own weight.

[0010] Furthermore, the hammer is an elastic sphere.

[0011] Furthermore, the pressing and releasing device includes a cam, which is fixedly connected to the motor shaft and is capable of rotating in the longitudinal plane where the axis of the swing rod is located.

[0012] Furthermore, the stacking position is provided with a stacking platform, which is raised and lowered so that the top of the stack of sheet metal can be flush with the sheet metal at the punching position.

[0013] Beneficial effects: The high-efficiency unloading mechanism of this utility model for a precision punching production line completes the rapid separation of sheet materials, precise stacking of sheet materials, and unloading of sheet materials relative to the unloading device through the cooperation of the sheet picker and the hammer, thereby achieving efficient unloading action, high degree of automation, low control cost, and ensuring the safety of workers.

[0015] Figure 2 This is a structural diagram of one embodiment of the present utility model. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As attached Figure 1-2 The high-efficiency unloading mechanism of a precision stamping production line includes a sheet-picking component 1, capable of picking up the blank 2 to be stamped. The sheet-picking component 1 is connected to a lifting drive device, which can press down the blank 2 when lowering and lift the blank 2 when rising. A hammer 3 is provided on one side of the sheet-picking component 1 and connected to a vertical swinging device, which can drive the hammer 3 to strike the blank 4 when the sheet-picking component 1 presses down the blank 2. The unloading of the blank 2 is completed by the cooperation of the sheet-picking component 1 and the hammer 3. During unloading, the sheet 2 is first pressed down by the sheet-picking component 1, and then the blank 4 on the side is struck by the hammer 3, which fixes the blank and makes the blank separate from the blank 4 quickly. Then, the hammer 3 presses down the blank 4, and the sheet 2 is picked up and lifted by the sheet-picking component 1. Then, the blank is carried away by rotation or movement to achieve unloading. In this process, the impact force generated by the hammer strike quickly releases the obstruction between the edge of the blank and the wall of the stamping hole, achieving efficient unloading. During sheet extraction, a hammer applies pressure to the sheet to prevent it from being lifted, ensuring stability during the cutting process and preventing the sheet's position from shifting due to the cutting and extraction actions. After punching, the sheet is in a fitted relationship with the punching hole. It is first adsorbed and pressed by the sheet extraction device, ensuring that each sheet is adsorbed in the same position, facilitating neat stacking during material preparation. The center position of the adsorbed sheet is preferred to ensure the longitudinal relative separation between the sheet and the material.

[0018] The swinging device includes a swing rod 5, which engages with a hinge seat in the middle. A long rod segment and a short rod segment are located on either side of the hinge. The end of the long rod segment is fixedly connected to the hammer 3, and the end of the short rod segment engages with a pressing device. The pressing device periodically applies downward pressure to the short rod segment. The engagement of the swing rod and the hinge seat forms a lever structure, with the longer end connected to the hammer maintaining a downward swing tendency under the hammer's own weight. The periodic pressure applied to the short rod segment by the pressing device lifts the hammer during pressure application and allows it to swing freely downward when the pressure is released, thus creating a periodic striking motion. When the pressing device does not apply pressure, the hammer naturally applies pressure to the sheet surface under its own weight.

[0019] The sheet-picking component 1 is fixedly connected to one end of the cantilever 6, and the other end of the cantilever 6 is fixedly connected to the rotating shaft of the rotating device, allowing the cantilever 6 to rotate horizontally and drive the sheet-picking component 1 to correspond with one of the punching position 10 and the stacking position 20. The rotating device is fixedly connected to the piston rod end of the longitudinal drive cylinder. This enables the sheet to be picked up from the punching position 10 and then transferred to the stacking position 20 for stacking. If the sheet-picking component 1 uses active adsorption, such as negative pressure adsorption or electromagnet adsorption, the unloading can be completed by actively removing the adsorption force when transferring to the stacking position 20. If passive adsorption is used, the unloading can be completed by manually removing the sheet when transferring to the stacking position 20. Preferably, the sheet-picking component rotates 180° from the punching position 10 to correspond with the stacking position 20. With consistent sheet adsorption position, cantilever length, and rotation angle each time, efficient material feeding and error-free, neat stacking are achieved.

[0020] Preferably, the sheet-retrieving component 1 is a magnetic block, requiring no extra energy consumption. Furthermore, the hinge seat and pressing device are both fixedly connected to the rotating table surface, capable of rotating and aligning the hammer 3 with either the punching position 10 or the stacking position 20. When the hammer 3 aligns with the stacking position 20, it can be placed on top of the sheet pile 21 under its own weight. This allows the hammer to serve as an auxiliary unloading mechanism.

[0021] Preferably, the hammer 3 is an elastic sphere. When the hammer 3 swings down to strike the sheet under its own weight, it can generate a certain rebound force, so that a single drive strike generates multiple vibrations from strong to weak, and can also form a buffer force, so that the striking force is not too large. By generating high-frequency small-amplitude vibration, the jamming is achieved, which not only improves the feeding speed, but also ensures the edge quality of the sheet.

[0022] The pressing and releasing device includes a cam 7, fixedly connected to the motor shaft, which can rotate in the longitudinal plane containing the axis of the swing rod 5. When the hammer is just placed on the upper surface of the sheet, the minimum radius of the cam 7 corresponds to the swing rod 5, and there is a small gap between the cam 7 and the swing rod 5, ensuring that it only acts on the surface of the sheet during impact. When the turntable rotates and the hammer leaves the area where the sheet is located, the swing rod 5 can contact the minimum radius of the cam, which constrains the hammer's downward swing limit position. By driving the cam 7 to rotate, when its maximum radius is perpendicular to the swing rod, the swing rod swings upward to its limit position.

[0023] The stacking position 20 is equipped with a stacking platform for stacking the removed sheet 2. Several limiting rods are set on the platform to constrain the longitudinal stacking state of the sheet stack and prevent the sheet from being loose or tilted. Since the swing height of the hammer and the lifting height of the sheet picking device are both limited, the stacking platform is set to be raised and lowered. As the stacking height of the sheet increases, the height of the stacking platform is gradually reduced so that the top of the sheet stack 21 can be kept flush with the sheet 2 of the punching position 10. In this way, the hammer 3 and the sheet picking device 1 only need to take the same action when feeding each sheet, without the need for complex precision control, thus reducing the cost of automation control.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
