[0026] Please see Figure 1This utility model discloses an automatic iron sheet stamping device, which includes a base 100, an upper die fixing plate 200, a lower die fixing plate 300, a drive mechanism 400, and a guide mechanism 500. The lower die fixing plate 300 is disposed on the top side surface of the base 100. One end of the guide mechanism 500 is connected to the top of the base 100, and the other end extends a preset distance away from the top of the base 100, thereby forming a guide module with a preset stroke. The drive mechanism 400 is disposed at the end of the guide mechanism 500 away from the base 100, and the output end of the drive mechanism 400 is slidably engaged with the guide mechanism 500, so that the output end of the drive mechanism 400 can reciprocate up and down along the guide mechanism 500. The upper die fixing plate 200 is disposed at the output end of the drive mechanism 400. Based on this, the drive mechanism 400 can drive the upper die fixing plate 200 to move up and down relative to the lower die fixing plate 300 along the guide mechanism 500 to complete the stamping process. Specifically, the guiding mechanism 500 includes a fixed plate 510, a plurality of guide posts 520, a plurality of stroke positioning components 530, and a plurality of guide rods 540. The fixed plate 510 is disposed on the top side of the base 100, and the plurality of guide posts 520 are disposed between the fixed plate 510 and the base 100. The two ends of each guide post 520 are respectively connected to the fixed plate 510 and the base 100, thereby forming a stable support structure. The driving mechanism 400 includes a movable plate 410 disposed between the fixed plate 510 and the base 100. The movable plate 410 is movably connected to the plurality of guide posts 520, thereby enabling the movable plate 410 to reciprocate along the plurality of guide posts 520 within the area between the fixed plate 510 and the base 100. The plurality of stroke positioning components 530... The stroke positioning components 530 are arranged along the stamping direction at the edge of the movable plate 410. One end of each stroke positioning component 530 is connected to the fixed plate 510, and the main body of the stroke positioning component 530 is movably engaged with the movable plate 410, thereby limiting the movement stroke of the movable plate 410. Several guide rods 540 are arranged on the adjacent side of the movable plate 410 and are movably engaged with the stroke positioning components 530. One end of each guide rod 540 is connected to the corresponding stroke positioning component 530. Thus, the several guide rods 540 can guide the relative movement between the movable plate 410 and the several stroke positioning components 530, thereby ensuring the stability of the engagement between the movable plate 410 and the stroke positioning components 530. Compared to existing sheet metal stamping equipment, the automatic sheet metal stamping device of this utility model effectively improves the accuracy of the movement stroke of the movable plate 410 through the cooperation between the stroke positioning component 530 and the guide rod 540. This improves the accuracy and stability of the cooperation between the upper and lower dies during the stamping process, thereby avoiding insufficient cooperation or collision between the upper and lower dies caused by inaccurate stroke positioning of the movable plate 410. This increases the yield of sheet metal stamping while reducing the risk of die damage.
[0027] Furthermore, in one embodiment, the stroke positioning components 530 are configured as two sets, with the two stroke positioning components 530 disposed opposite to each other on both sides of the fixed plate 510, and respectively movably cooperating with both sides of the movable plate 410, thereby ensuring the stroke positioning accuracy and stability of the movable plate 410.
[0028] Furthermore, each stroke positioning component 530 includes two stroke positioning elements 531, two stroke adjusting rods 532, and a connecting member 533. The two stroke positioning elements 531 are respectively disposed at both ends of the corresponding side edge of the fixed plate 510, and each stroke positioning element 531 extends towards the movable plate 410 by a predetermined distance. The two stroke adjusting rods 532 are respectively movably engaged with the two ends of the corresponding side of the movable plate 410 along the moving direction of the two stroke positioning elements 531, and the top end of each stroke adjusting rod 532 is threadedly connected to the corresponding stroke positioning element 531. The connecting member 533 is disposed on the bottom side of the movable plate 410 and is correspondingly connected to the bottom end of the two stroke adjusting rods 532. At the same time, the end of the connecting member 533 is connected to the bottom end of the corresponding side guide rod 540, thereby realizing the connection between the stroke adjusting rod 532 and the corresponding guide rod 540. In practical applications, the movement stroke of the movable plate 410 relative to the fixed plate 510 is adjusted by adjusting the engagement depth between the stroke adjusting rod 532 and the stroke positioning element 531.
[0029] Furthermore, in one embodiment, four guide rods 540 are provided, with each pair of guide rods 540 correspondingly disposed at both ends of a stroke positioning component 530. Specifically, the two guide rods 540 on the corresponding sides are respectively movably engaged with the movable plate 410, and the bottom ends of the two guide rods 540 are respectively connected to the two ends of the corresponding connectors 533, thereby ensuring the stability of the engagement between the stroke positioning component 530 and the movable plate 410.
[0030] Furthermore, the movable plate 410 is provided with four guide sleeves 411 corresponding to the four guide rods 540. The four guide sleeves 411 are provided on the side surface of the movable plate 410 along the moving direction of the movable plate 410, and the four guide sleeves 411 are respectively sleeved on the side surface of the four guide rods 540, thereby realizing the movable connection between the four guide rods 540 and the movable plate 410.
[0031] Furthermore, the drive mechanism 400 also includes a hydraulic cylinder 420, which is disposed on the top side surface of the fixed plate 510. The main cylinder shaft of the hydraulic cylinder 420 extends through the fixed plate 510 to the bottom side of the fixed plate 510 and is connected to the movable plate 410, thereby driving the movable plate 410 to perform a stamping action along a plurality of guide posts 520.
[0032] Furthermore, each guide post 520 is threadedly connected to the base 100 so that the automatic sheet metal stamping device can adjust the overall height of the equipment and the stamping process according to the actual production situation.
[0033] Furthermore, one end of each guide post 520 is connected to the top side of the fixing plate 510 and then threadedly connected to a matching nut to facilitate the flexible assembly and disassembly of the fixing plate 510.
[0034] In summary, the automatic sheet metal stamping device disclosed in this utility model uses a drive mechanism to drive the upper die fixing plate to move up and down relative to the lower die fixing plate along a guide mechanism to complete the stamping process. During the stamping process, the movable plate can reciprocate along several guide posts within the area between the fixing plate and the base; the stroke positioning component can limit the movement stroke of the movable plate; several guide rods are arranged adjacent to the movable plate and move in cooperation with the stroke positioning component, with one end of each guide rod connected to the corresponding stroke positioning component. Thus, the several guide rods can guide the relative movement between the movable plate and the several stroke positioning components, thereby ensuring the stability of the cooperation between the movable plate and the stroke positioning components. Compared with existing sheet metal stamping equipment, the automatic sheet metal stamping device of this utility model effectively improves the accuracy of the movable plate's movement stroke through the cooperation between the stroke positioning component and the guide rods, that is, improves the accuracy and stability of the cooperation between the upper and lower dies during the stamping process, thereby avoiding insufficient cooperation or collision between the upper and lower dies caused by inaccurate stroke positioning of the movable plate. This improves the yield of sheet metal stamping while reducing the risk of die damage.
