[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a pendulum-type negative angle side shaping slider mechanism for a stamping die, including a first die 1, a second die 2, and a workpiece 3. The first die 1 moves downward to the second die 2, thereby extruding and shaping the workpiece 3. The mechanism is characterized by including: a pressure core 5, a fixing block 6, and a bearing block 7 between the first die 1 and the second die 2. The fixing block 6 and the bearing block 7 are fixed to the second die 2 and will not move, ensuring that no deviation occurs when extruding and shaping the negative angle 31 on the workpiece 3. The first mold 1 drives the connecting block 4 to press downwards, thereby pressing the negative angle 31 downwards and forming the negative angle 31. The pressure core 5, the fixing block 6 and the bearing block 7 cooperate to process the negative angle 31 on the workpiece 3. The bearing block 7 is equipped with a detachable slider 72. In order to facilitate the pressure core 5 to press downwards better, the slider 72 will move upwards on the slide 71, and then the workpiece 3 is placed on the slide 71. Then the slider 72 moves downwards together with the pressure core 5 to press the negative angle 31. The slider 72 slides and cooperates with the pressure core 5 to press the negative angle 31 into shape.

[0027] The first mold 1 is driven to move downwards to the second mold 2, preparing to extrude and form the workpiece 3. At this time, the fixing block 6 and the bearing block 7 fixed on the second mold 2 remain stationary, providing stable support for processing and ensuring no deviation occurs when extruding and forming the negative angle 31 on the workpiece 3. Driven by the first mold 1, the pressure core 5 is synchronously pressed downwards through the connecting block 4, working in coordination with the fixing block 6 and the bearing block 7 to precisely act on the negative angle 31 area of ​​the workpiece 3. The detachable slider 72 on the bearing block 7 plays a key role. Initially, to facilitate the downward movement of the pressure core 5, the slider 72 first moves upwards on the slide 71 to make room for the workpiece 3. Then, the slider 72 moves downwards together with the pressure core 5, and the two slide closely together, gradually applying pressure to the negative angle 31, so that it is finally pressed and formed. In the whole process, each component performs its own function and works closely together to efficiently complete the negative angle 31 stamping task.

[0028] Please see Figure 4-6A first extrusion surface 61 is provided on one side of the fixing block 6. The first extrusion surface 61 is a side formed inside the fixing block 6, used to limit the stamping end of the pressure core 5, ensuring that the pressure core 5 will not rotate outward when stamping the negative angle 31, thus preventing deviation of the stamping angle. The first extrusion surface 61 is used to fix the pressure core 5, and the curvature of the first extrusion surface 61 matches the angle of the stamping section of the pressure core 5, ensuring that the pressure core 5 can still be inserted into the center of the fixing block 6 and the bearing block 7 despite the friction of the first extrusion surface 61, ensuring the stability of the pressure core 5 when processing the negative angle 31. A connecting rod 51 is provided, which is used to connect the connecting block 4 and the pressing core 5 to ensure that the pressing core 5 can rotate slightly in the connecting block 4. The two ends of the connecting rod 51 are connected to the connecting block 4. The connecting block 4 is used to connect the pressing core 5 and the first mold 1, so that the pressing core 5 can be driven to move up and down. The connecting block 4 is provided with a fixing plate 41 for fixing the pressing core 5. The fixing plate 41 is used to fix the pressing core 5 connected to the connecting block 4. The connecting block 4 is provided with a receiving groove 42, and a connecting groove is provided on the receiving groove 42 for receiving the connecting rod 51.

[0029] During the stamping operation, the first extrusion surface 61 on the inner side of the fixed block 6 plays a crucial role. When the blank holder 5 is pressed down toward the negative angle 31 of the workpiece 3, the first extrusion surface 61, with its arc precisely matched with the stamping section of the blank holder 5, tightly abuts against the stamping end of the blank holder 5. On the one hand, the friction generated effectively prevents the blank holder 5 from rotating outward due to force, avoiding deviation in the stamping angle; on the other hand, it keeps the blank holder 5 stably in the center position between the fixed block 6 and the bearing block 7, ensuring stability when processing the negative angle 31. At the same time, the connecting rod 51 on the blank holder 5 is connected to the connecting block 4, which not only achieves a stable connection between the two, but also allows the blank holder 5 to rotate slightly within the connecting block 4, flexibly adjusting its posture to adapt to subtle changes during the stamping process. The connecting block 4 acts as a hub, connecting one end to the first mold 1 and moving up and down with it, thereby driving the pressing core 5 to move synchronously; the other end is fixed by the fixing plate 41 to fix the pressing core 5 again to prevent it from shaking excessively, and the receiving groove 42 and connecting groove opened inside it accurately accommodate the connecting rod 51, ensuring that the entire structure works in coordination and accurately and efficiently completes the stamping task of the negative angle 31.

[0030] The bottom of the pressure core 5 is provided with a pressure head 52. After stamping, the pressure head 52 fits against one side of the negative angle 31 so that the negative angle 31 can be formed. The pressure head 52 works with the bearing block 7 to process and form the negative angle 31. The bearing block 7 is provided with a slide 71, which is used to support the slider 72 to slide on it. The slider 72 is slidably mounted on the slide 71, and the workpiece 3 is mounted on the slider 72. During stamping, the slider 72 and the connecting rod 51 slide down synchronously to stamp the negative angle 31. The slider 72 and the pressure core 5 work together. The initial angle of the pressure head 52 is 45 degrees, and the angle of the slide 71 is 60 degrees. There is a space between the fixing block 6 and the bearing block 7. The size of the space matches the size of the pressure core 5. The pressure core 5 is driven downward by the first mold 1.

[0031] When the pendulum-type negative angle side forming slider mechanism of the stamping die is used, the pressure core 5, driven by the first die 1, is pressed downward by the connecting block 4, and cooperates with the fixed block 6 and the bearing block 7 to lock the negative angle 31 area of ​​the workpiece 3. The detachable slider 72 of the bearing block 7 first slides upward along the slide 71 to make room for the workpiece 3, and then slides downward with the pressure core 5. The two slide in cooperation to apply pressure to the negative angle 31. The first extrusion surface 61 on the inner side of the fixed block 6 is the key to the stamping accuracy. When the pressure core 5 is stamping, the first extrusion surface 61 abuts against the stamping end with the arc matching the stamping section to prevent the pressure core 5 from rotating and keep its position stable. The connecting rod 51 of the pressure core 5 is connected to the connecting block 4, allowing the pressure core 5 to rotate slightly to adapt to the stamping changes. One end of the connecting block 4 is connected to the first die 1 to drive the pressure core 5 to rise and fall, and the other end is fixed by the fixing plate 41 to fix the pressure core 5. Its receiving groove 42 and connecting groove are adapted to the connecting rod 51. Furthermore, after the bottom pressure head 52 of the pressure core 5 is stamped, it fits against one side of the negative angle 31, working in conjunction with the support block 7 to process the negative angle 31. The slide 71 of the support block 7 is 60 degrees, allowing the slider 72 to slide, so that the workpiece 3 on the slider 72, the slider 72, and the connecting rod 51 slide down synchronously to stamp the negative angle 31. The space between the fixed block 6 and the support block 7 matches the size of the pressure core 5, and the cooperation of each component realizes the stamping forming of the negative angle 31.
