DETAILED DESCRIPTION
[0016] The utility model is further described below with reference to the accompanying drawings.
[0017] like Figures 1 to 3 As shown, one end of the top seat 9 is connected to the bending punch 1, and the base 8 is provided with a bending die 2. The left and right sides of the bending die 2 are respectively provided with a sliding block 1 4.1 and a sliding block 2 4.2. The upper ends of the inner sides of the sliding block 1 4.1 and the sliding block 2 4.2 are respectively embedded with a roller 1 6.1 and a roller 2 6.2. The outer sides of the sliding block 1 4.1 and the sliding block 2 4.2 are respectively connected with a spring 5. The spring 5 provides a flexible terminal for the decomposition of the collision force and restores the sliding block 1 4.1 and the sliding block 2 4.2 to their original positions after bending.
[0018] A bent product 3 is provided between the bending punch 1 and the bending punch 2 .
[0019] Roller 1 6.1 and roller 2 6.2 are in rolling connection with the bending product 3. Roller 1 6.1 and roller 2 6.2 decompose the bending product 3 to receive a part of the pressure when the bending product 3 is bent.
[0020] The left and right sides of the concave part of the bending die 2 are respectively provided with R-angle 7 structures, which avoid stress concentration and can alleviate the collision force at the bending point.
[0021] The bending die 2 is located below the bending punch 1 .
[0022] The left and right sides of the bending die 2 are provided with grooves 10 for the sliding block 1 4.1 and the sliding block 2 4.2 to move.
[0023] A spring groove 11 is provided in the base 8 , one end of the spring 5 is connected to the sliding block 1 4 . 1 or the sliding block 2 4 . 2 , and the other end of the spring 5 is fixed in the spring groove 11 .
[0024] Roller 1 6.1 and roller 2 6.2 are connected to the bending die 2 and the R angle 7 structures on both sides respectively.
[0025] In the specific implementation process of the utility model, the relevant technicians in this field place the bending product 3 on the base 8, ensure that the bending point of the bending product 3 is exactly located between the convex point of the bending punch 1 and the R angle 7 vertex of the bending die 2, and ensure that the lower surface of the bending product 3 is in contact with the roller 1 6.1 and the roller 2 6.2. During the bending process, the bending punch 1 is pressed down, so that the state of the bending product 3 changes from Figure 2 Convert to Figure 1 ,like Figure 1 As shown, during the bending process of the bending product 3, the roller 1 6.1 and the roller 2 6.2 are subjected to the downward pressure of the bending punch 1, and the roller 1 6.1 and the roller 2 6.2 roll relative to the bending product 3 and contact the R angle 7. The downward pressure is converted by the roller 1 6.1 and the roller 2 6.2 into a thrust for pushing the sliding block 1 4.1 and the sliding block 2 4.2 by 90 degrees, which is specifically manifested as the sliding block 1 4.1 and the sliding block 2 4.2 moving horizontally away from the bending punch 1. Finally, the force is buffered by the spring 5, and the bent product 3 contacts the R angle 7, which reduces the friction between the bent product and the workpiece and ensures that the product is not scratched by the workpiece. When the operation is completed, the driving device controls the bending punch 1 to lift up, and the spring 5 is no longer subjected to force, so that the sliding block 1 4.1 and the sliding block 2 4.2 rebound to the initial position. At this time, the roller 1 6.1 and the roller 2 6.2 in the sliding block 1 4.1 and the sliding block 2 4.2 eject the bending material 7 out of the bent product 3, completing the product removal.
