[0002] Stamping dies are important tools used in metal forming and processing. They mainly apply pressure to metal sheets through a stamping press to achieve effects such as shearing, bending, and stretching. Stamping dies consist of a die cavity, guiding device, and unloading system. The design must take into account the material properties, stamping process requirements, and die durability. They are widely used in industries such as automobiles, home appliances, and electronics, enabling the efficient mass production of precision metal parts. The manufacturing of stamping dies requires high precision and wear resistance to ensure product quality and production efficiency.

A buffer block is fixedly connected to the top of the rack 5. 4. Fixed base 12 is fixedly connected to fixed base 7 on its front side. Fixed base 7 has two positioning blocks 13 fixedly connected to its top. Fixed base 12 has a slider 9 fixedly connected to its rear side. A roller 8 is rotatably connected to the rear side of slider 9. Base plate 15 is used to support and connect the entire device. Guide pressure block 3 is used to install fixed base 12. Fixed base 12 is used to connect and protect internal components. Bearing 10 is used to make gear 11 rotate within fixed base 12. Gear 11 is used to drive insert 6 to rotate. Insert 6 is used to twist part 14. Rack 5 is used to drive gear 11 to rotate. Buffer block 4 is used for... To protect rack 5 and prevent wear during pressing, a fixed base 7 supports part 14, and a positioning block 13 fixes part 14 to keep it stable. A slider 9 supports roller 8, which enables linear movement of drive block 2. A side force block 1 is fixedly connected to the top of base plate 15, and a drive block 2 is slidably connected to the front side of base plate 15. The side force block 1 keeps drive block 2 stable, and drive block 2 moves between side force block 1 and roller 8. The front of drive block 2 abuts against the outside of roller 8, and the bottom of drive block 2 abuts against the inside of base plate 15, ensuring the stability of drive block 2. To maintain stability, the slider 9 is externally fixedly connected to the inside of the guide block 3, keeping the slider 9 stable.

Through the buffer block 4 meshing with gear 11, and with the cooperation of two bearings 10, it drives gear 11 to rotate in fixed seat 12, causing insert 6 to rotate synchronously. At this time, insert 6 will drive part 14 to twist until it is twisted to 90 degrees. Then, release positioning block 13, remove part 14 to complete the processing of one part 14. Finally, let rack 5 return to its original position, and the next part 14 can be processed. The operation is convenient and labor-saving.
