[0020] Embodiment
[0021] In the prior art, the stamping and bending structure used in the current market is relatively simple. After stamping and bending the sheet material, the two sides of the stamped sheet material are prone to rebound, resulting in problems of poor product dimensions.
[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a stamping and bending mechanism, including a bottom plate 1. A lower fixing block 2 is fixedly arranged on the top of the bottom plate 1. A bent product 3 is arranged on the top of the lower fixing block 2. A side pressing structure is arranged on the top of the bottom plate 1. A top plate 9 is arranged above the bottom plate 1. Two bending blocks 10 are fixedly arranged on the bottom of the top plate 9. Two connecting plates 11 are fixedly arranged at both ends of the top plate 9. A push rod 12 is slidably arranged inside the top plate 9. The bottom end of the push rod 12 is provided with a pressing plate 13 and the pressing plate 13 is located between the two bending blocks 10. A connecting head 14 is arranged on the top of the pressing plate 13. When stamping the sheet material, place the bent product 3 on the top of the lower fixing block 2, then fix it through the pressing plate 13, and then stamp and bend the bent product 3 on the top of the lower fixing block 2 through the bending blocks 10. At the same time, the side pressing structure will also squeeze the two sides of the bent product 3 to fit with the two sides of the lower fixing block 2, so as to reduce the rebound force of the stamped bent product 3, improve the dimensional stability, and avoid poor dimensions.
[0023] The side pressing structure includes two fixed seats 4 which are fixedly installed on the top of the bottom plate 1. The lower fixed block 2 is located between the two fixed seats 4. On one side of each of the two fixed seats 4, there is a side slider 5. One side of the side slider 5 is integrally processed with a slide plate 6, and the slide plate 6 is slidably installed on the inner wall of one side of the fixed seat 4. One side of the slide plate 6 is fixedly provided with a fixing plate 7. The bottom of the fixing plate 7 is inserted with a spring 8, and the bottom end of the spring 8 is connected to the bottom plate 1. When the bending block 10 moves downward, the bending block 10 will squeeze the side slider 5 to move downward, so that the side slider 5 squeezes both sides of the bent product 3, making both sides of the bent product 3 completely fit with both sides of the lower fixed block 2, thereby reducing the rebound force.
[0024] The cross-section of the lower fixed block 2 is processed into a shape that is wider at the top and narrower at the bottom, so that the bent product 3 bends during stamping, reducing the elastic force.
[0025] A chute is opened on the inner wall of one side of the fixed seat 4, and the slide plate 6 is slidably installed inside the chute. The side slider 5 is slidably installed on one side of the fixed seat 4 through the slide plate 6.
[0026] A through hole is opened inside the top plate 9, and the push rod 12 passes through the through hole. The pressing plate 13 is slidably installed below the top plate 9 through the push rod 12.
[0027] The cross-section of the connecting plate 11 is processed into a right angle, and a connecting hole is opened inside the connecting plate 11. It is convenient to connect the top plate 9 to the outside through the connecting plate 11.
[0028] During the working principle or structural principle, when stamping a sheet, the top plate 9 and the push rod 12 are connected to an external hydraulic cylinder through the connecting plate 11 and the connecting head 14. Then, the bent product 3 is placed on the top of the lower fixed block 2. The push rod 12 is used to push the pressing plate 13 to move, so as to fix the bent product 3 on the top of the lower fixed block 2. Then, the top plate 9 is used to push the bending block 10 to move downward, and the bending block 10 will push the side slider 5 to slide, so that the bending block 10 and the side slider 5 stamp the bent product 3 on the top of the lower fixed block 2. The side slider 5 will slide inside the fixed seat 4 through the slide plate 6, so as to laterally slide and squeeze the bent product 3, making both sides of the bent product 3 fit with both sides of the lower fixed block 2, thereby reducing the rebound force after stamping and avoiding dimensional defects. At the same time, when the side slider 5 moves downward, the spring 8 will deform. After stamping, the deformed spring 8 will push the side slider 5 to move upward, facilitating the next stamping.
