[0002] Press brake dies play an important role in metalworking. They are often used to bend sheet metal materials into specific shapes, such as angles, arcs, or complex curves. The design of the dies ensures the precision and stability of the material during the bending process, thereby ensuring the quality and accuracy of the finished product. In addition, the dies can be customized according to different needs and design requirements to adapt to the bending needs of various workpieces.

The bending machine cannot effectively limit and control the length and position of the sheet metal material, which will increase the amount of unnecessary waste and affect production efficiency and cost control.

The driven rotating column is movably installed inside the bending die. The driven gear ring is uniformly installed on the outer surface of the driven rotating column, and the outer surface of the driven gear ring meshes with the outer surface of the active gear ring.

[0011] As a preferred technical solution of the present utility model, limiting sliding grooves are uniformly opened inside the bending die.

[0023] Reference Figure 1 、 Figure 3 、 Figure 4 and Figure 5, the present utility model discloses a bending machine die with a limiting function, including a bending die 1 and a cutting groove 6 opened on the outer surface of the bending die 1. There is a bending arc surface 4 on the bending die 1. The convenient material taking assembly includes a driven rotating column 15 and a driven gear ring 14. The driven rotating column 15 is movably installed inside the bending die 1, and the driven gear ring 14 is evenly installed on the outer surface of the driven rotating column 15. The outer surface of the driven gear ring 14 meshes with the outer surface of the driving gear ring 13. Limiting sliding grooves 19 are evenly opened inside the bending die 1, and limiting sliding blocks 18 are movably installed inside the limiting sliding grooves 19. One end surface of the limiting sliding block 18 is provided with a driven gear rack 16, and the outer surface of the driven gear rack 16 meshes with the outer surface of the driven gear ring 14. The top surface of the limiting sliding block 18 is provided with an arc surface pushing block 17. The return spring 9 has elastic deformation, so that the limiting pressing block 7 and the arc surface pushing block 17 return to their original positions. The arc surface pushing block 17 pushes the bent sheet metal material, which is convenient to take out the bent sheet metal material, convenient to take out from the bending machine, beneficial to subsequent processing and assembly steps, saves the time of the operator, and maintains the stability and consistency of the bending process.

[0024] The working principle and usage process of the present utility model: When it is necessary to bend the arc of the sheet metal material, one end surface of the sheet metal material corresponds to one end surface of the limiting pressing block 7. The bending machine bends the sheet metal material through the hydraulic system. The bending block bends the bending die 1, and the bending block squeezes the limiting pressing block 7. The limiting pressing block 7 moves into the first cavity 2, and the limiting pressing block 7 drives the clamping block 8 to squeeze a plurality of return springs 9, so that the top surface of the limiting pressing block 7 is on the same horizontal line as the upper end surface of the bending die 1, and the clamping block 8 synchronously drives the connecting block 10 to move into the second cavity 3, so that the connecting block 10 drives the driving gear rack 11 to move. The outer surface of the driving gear rack 11 meshes with the outer surface of the driving gear ring 13. The driving gear rack 11 makes the driving gear ring 13 drive the driving rotating column 12 to rotate. The outer surface of the driving gear ring 13 meshes with the outer surface of the driven gear ring 14. The driving gear ring 13 drives the driven gear ring 14 and the driven rotating column 15 to rotate. The outer surface of the driven gear ring 14 meshes with the outer surface of the driven gear rack 16, so that the driven gear rack 16 drives the limiting sliding block 18 to move in the limiting sliding groove 19, so that the arc surface pushing block 17 moves towards the second cavity 3, so that the top arc surface of the arc surface pushing block 17 is on the same horizontal plane as the bending arc surface 4.

[0025] When the bending block bends the sheet metal material, the sheet metal material closely adheres to one end of the limit pressing block 7, keeping the length within the standard range. When the bending block performs bending, the entire sheet metal material is bent into the bending arc surface 4, and there is no waste of the sheet metal material near one end of the limit pressing block 7, minimizing the waste of the sheet metal material to the greatest extent. Because the part near one end of the limit pressing block 7 does not need to be cut or discarded, this efficiency and precision help improve production efficiency and reduce costs, while ensuring product quality and consistency. The supporting arc block 5 makes the angle at the bending part complete, and only the surface of one end of the sheet metal material needs to be cut. When the sheet metal material is bent, the return spring 9 has elastic deformation, causing the limit pressing block 7 and the arc surface pushing block 17 to return to their original positions. The arc surface pushing block 17 pushes the bent sheet metal material, facilitating the removal of the bent sheet metal material, making it convenient to take out from the bending machine, which is beneficial for subsequent processing and assembly steps, saving the operator's time, and maintaining the stability and consistency of the bending process.
