[0025] To clearly and completely describe the objectives and technical solutions of this utility model, and to more clearly illustrate its advantages, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 7 This utility model provides an automatic loading and unloading metal terminal stamping die, including a base frame 1. A flip-over pressure seat 32 is rotatably mounted on the base frame 1 via a rotatable shaft 7. A lower die base 30 for supporting a metal workpiece 29 is fixed on the flip-over pressure seat 32. A mating pressure block 6 is fixed to the end of the shaft 7. A limiting post 5 is fixed to the side of the base frame 1, corresponding to the mating pressure block 6 and used to limit the rotation of the shaft 7 to the left. When the flip-over pressure seat 32 flips to the left, when the mating pressure block 6 contacts the limiting post 5, the top of the flip-over pressure seat 32 will be in a horizontal state. The base frame 1 is equipped with a stamping push rod 10, and the output end of the stamping push rod 10 is fixed with a punch 16 for stamping the metal workpiece 29. The stamping push rod 10 can be a hydraulic push rod. The punch 16 is selected or customized according to the processing required for the metal workpiece 29. During the stamping process of the punch 16, the impact pressure will be borne by the rotating shaft 7 and the limiting post 5, thereby preventing the flipping pressure seat 32 from accidentally flipping.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7A gear 22 is coaxially fixed on the rotating shaft 7, and a first torsion spring 31 is installed between the rotating shaft 7 and the base frame 1. A top frame 25 is fixedly installed on the base frame 1 by bolts, and a stamping push rod 10 is fixedly installed on the top frame 25. A push plate 15 is fixed to the output end of the stamping push rod 10, and a punch 16 is fixedly installed at the bottom of the push plate 15. A push rod 12 is slidably installed on the top frame 25, and the push rod 12 is connected to the top frame 25 by a first compression spring 11. A rack 14 that meshes with the gear 22 is fixed to the end of the push rod 12, and a retaining ring 13 for pressing the push plate 15 is fixed above the push rod 12. After the punch 16 completes the stamping of the metal workpiece 29 downwards, the punching push rod 10 drives the punch 16 to rise upwards. At this time, the push plate 15 will also continue to rise upwards until the retaining ring 13 contacts the pressing push plate 15. Then, the push plate 15 will drive the retaining ring 13 to continue to rise upwards until the highest point. During this process, the retaining ring 13 will drive the push rod 12 to move upwards, and the push rod 12 will drive the rack 14 to move upwards. Through the meshing of the rack 14 and the gear 22, the rotating shaft 7 will be driven to rotate to the right. At this time, the flipping pressure seat 32 will follow the rotating shaft 7 to rotate 135° to the right, so that the metal workpiece 29 that has been processed in the lower die seat 30 is discharged from the right side of the base frame 1, thereby realizing automatic unloading. After the metal workpiece 29 is discharged, the push plate 15 moves downward to the non-working position. At this time, the punch 16 is in the non-working position, and the retaining ring 13, lacking the upward pressing force of the push plate 15, is pushed downward by the push rod 12 under the push of the first compression spring 11. This drives the rotating bearing seat 32 to rotate to the left by the rack 14 until the mating pressure block 6 presses against the limiting post 5. At this time, the upper end of the rotating bearing seat 32 will be in a horizontal position. During this process, the first torsion spring 31 will also play a role in rotating the rotating bearing seat 32 to the left. Therefore, as long as either the first compression spring 11 or the first torsion spring 31 is working properly, the rotating bearing seat 32 can be rotated to a horizontal position at the top, increasing the reliability of the equipment. When the top of the rotating bearing seat 32 is in a horizontal position, the metal workpiece 29 can be placed in the lower die base 30 to wait for the next punching operation of the punch 16.

[0028] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6A guide device 2 is provided on the base frame 1, and the guide device 2 includes a guide ring 201 coaxial with the rotating shaft 7 and fixed to the base frame 1. A concave surface 203 is provided in the middle of the side of the guide ring 201, and protruding surfaces 202 are provided at the upper and lower ends of the side of the guide ring 201. The concave surface 203 and the protruding surface 202 are smoothly connected and transitioned. A ball-head push rod 27 is slidably installed on the flipping pressure seat 32, pressing against the concave surface 203. The ball-head push rod 27 is connected to the flipping pressure seat 32 through a third compression spring 36. A rotating rod 34 is rotatably installed inside the flipping pressure seat 32, and a second torsion spring 35 is installed between the rotating rod 34 and the flipping pressure seat 32. The bottom of the rotating rod 34 presses against the end of the ball-head push rod 27, and the top of the rotating rod 34 presses against the bottom of the metal workpiece 29. When the flipping pressure seat 32 is in a horizontal position, the ball head of the ball push rod 27 will press against the recessed surface 203. At this time, under the action of the second torsion spring 35, the top of the rotating rod 34 is located at the bottom of the metal workpiece 29 and will not contact the metal workpiece 29. When the flipping pressure seat 32 flips to the right, the ball head of the ball push rod 27 will also follow the flipping movement of the flipping pressure seat 32 to the protruding surface 202. At this time, the ball push rod 27 will move towards the interior of the flipping pressure seat 32 under the pressure of the protruding surface 202, so that the end of the ball push rod 27 can push the rotating rod 34 to... The rotation causes the top of the rotating rod 34 to press the metal workpiece 29 upward, thereby causing the metal workpiece 29 to be ejected from the lower mold base 30 and properly separated under the pressure of the rotating rod 34. Subsequently, when the flipping pressure seat 32 flips to the left again until the top is in a horizontal position, the ball head of the ball push rod 27 is once again pressed into the concave surface 203 by the third compression spring 36. At the same time, since the pressure of the ball push rod 27 on the bottom of the rotating rod 34 is reduced at this time, the rotating rod 34 will return to the non-working position under the drive of the second torsion spring 35, so that the metal workpiece 29 can be properly installed in the lower mold base 30.

[0029] Please see Figures 1 to 4 A loading cylinder 24 for stacking metal workpieces 29 is fixedly installed above the base frame 1. A lead screw motor 8 for driving a movable seat 9 to slide back and forth along the guide rail on the base frame 1 is fixedly installed at the front end of the base frame 1. A pusher plate 23 for pushing the metal workpiece 29 located at the bottom of the loading cylinder 24 into the lower die base 30 is fixedly installed on the movable seat 9. A controller 3 is fixedly installed on the base frame 1, and the controller 3 is electrically connected to the lead screw motor 8 and the stamping push rod 10. The metal workpieces 29 stacked in the loading cylinder 24 will move to the bottom of the loading cylinder 24 under their own weight. Then, when waiting for loading in the lower die base 30, the lead screw motor 8 will drive the pusher plate 23 to push the metal workpiece 29 located at the bottom of the loading cylinder 24 into the lower die base 30, thereby completing the loading.

[0030] Working principle: The automatic loading and unloading metal terminal stamping die designed in this solution can automatically complete the loading and unloading of metal workpieces 29, thereby effectively replacing manual loading and unloading operations. This not only improves work efficiency, but also avoids accidents caused by operator error. Specifically, the worker only needs to stack the metal workpiece 29 into the loading cylinder 24. Driven by the lead screw motor 8, the pusher plate 23 pushes the metal workpiece 29 at the bottom of the loading cylinder 24 into the lower die holder 30. Then, driven by the stamping push rod 10, the punch 16 completes the stamping operation on the metal workpiece 29 in the lower die holder 30. Subsequently, the push plate 15 drives the retaining ring 13 to move upward, thereby using the rack 14 to drive the flipping pressure seat 32 to flip 135° to the right. At this time, the ball head push rod 27 also pushes the rotating rod 34 to rotate, thereby using the rotating rod 34 to push the processed metal workpiece 29 out of the lower die holder 30, completing the discharge of the processed metal workpiece 29. Then, the push plate 15 moves downward to the non-working position, and the flipping pressure seat 32 will flip to the left under the combined action of the first compression spring 11 and the first torsion spring 31, so that the top is in a horizontal state, thus facilitating the next round of loading and stamping. Using the above method can effectively reduce accidents and improve production efficiency.

[0031] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 Based on Embodiment 1, a pressing plate 20 for pressing metal workpiece 29 is provided below the push plate 15, and a side limiting plate 21 is installed at the bottom of the pressing plate 20 and sleeved on the side of the flipping pressure seat 32 to prevent the flipping pressure seat 32 from rotating during stamping. A guide slide rod 18 that is slidably installed with the push plate 15 is fixedly installed at the top of the pressing plate 20, and an anti-detachment limiting ring 17 for preventing the guide slide rod 18 from sliding out of the push plate 15 is fixedly installed at the top of the guide slide rod 18. A second compression spring 19 is installed between the pressing plate 20 and the push plate 15. During the stamping process, when the push plate 15 moves downward, before the punch 16 presses against the metal workpiece 29, the extrusion plate 20, driven by the second extrusion spring 19, first presses against the non-stamping area of ​​the metal workpiece 29. Simultaneously, the side limiting plates 21 are also clamped onto the left and right sides of the flipping pressure seat 32. This utilizes the extrusion plate 20 to restrict the movement of the metal workpiece 29, thereby improving stamping accuracy, and the side limiting plates 21 to restrict the left and right swaying of the flipping pressure seat 32, further improving stamping accuracy. After stamping, as the push plate 15 moves upward, the second extrusion spring 19 pulls the extrusion plate 20 upward, causing the extrusion plate 20 and the side limiting plates 21 to disengage from the flipping pressure seat 32. This prevents the extrusion plate 20 and the side limiting plates 21 from restricting the flipping movement of the flipping pressure seat 32.

[0032] Example 3: Please refer to Figures 1 to 6 Based on Embodiment 2, a waste discharge port 4 for discharging stamping waste is provided on the left side of the base frame 1, and a workpiece discharge port 28 for discharging processed metal workpieces 29 is provided on the right side of the base frame 1. A guide plate 33 for guiding stamping waste into the waste discharge port 4 is fixedly installed at the bottom of the flip-over pressure seat 32, and a baffle plate 26 is fixedly installed above the corresponding waste discharge port 4 and workpiece discharge port 28 on the base frame 1. The baffle plate 26 is used to prevent stamping waste and processed metal workpieces 29 from splashing out from above the base frame 1. By placing corresponding collection equipment at the outlets of the waste discharge port 4 and workpiece discharge port 28, the stamping waste and processed metal workpieces 29 can be effectively collected, avoiding the trouble of manual collection and further saving labor costs.
