[0024] like Figures 1 to 4As shown, this embodiment discloses a progressive punching and bending machine for processing metal products, which continuously and progressively feeds strip metal plates of uniform width into the punching and bending machine through a conveying device, thereby continuously processing single metal products. The punching and bending machine specifically includes a lower die base 1 fixed on a workbench, a guide column 2 vertically installed on the lower die base 1, and an upper die base 3 slidingly fitted on the guide column 2. The upper die base 3 is connected to a hydraulic press to realize a downward punching action. A lower template 4 is provided on the top of the lower die base 1, and a conveying base 5 for carrying the metal plate is detachably installed on the lower template 4. An upper template 6 is provided on the bottom of the upper die base 3, and a punching head 7 is detachably installed on the upper template 6. The conveying base 5 includes a punching base 51 and a trimming base 5 in the conveying direction. 2. Bending base 53 and cutting base 54. Each of the above bases is arranged in sequence according to the unit length of a metal product. The punch head 7 includes a punching punch 71, a trimming punch 72, a bending punch 73 and a cutting punch 74 in the conveying direction. Each of the above punches is arranged in sequence according to the unit length of a metal product. The conveying mechanism drives the strip metal plate to move along the conveying base 5 by a distance of a unit length of the metal product each time, so that the strip metal plate forms a single metal product after being punched, trimmed, bent and cut in sequence. This not only improves production efficiency but also saves production costs. In addition, during the processing of the metal product, it can always be connected to the strip metal plate, thereby reducing the precision caused by product transfer and improving product precision. Not limited to the above embodiment, the positions of the punching base 51, the trimming base 52 and the bending base 53 can be adjusted in sequence according to the specific structure of the metal product so that they can be applied to different metal products and improve practicality.

[0025] In this embodiment, since the metal parts will generate a large amount of heat during the stamping and bending process, this heat will cause the metal parts to deform. Therefore, when multiple punching holes need to be punched on the metal part product, the multiple punching holes are punched in multiple steps. The punching punches 71 are provided in plurality, and the multiple punching punches 71 are arranged in sequence according to the unit length of a metal part product along the conveying direction of the metal plate. Similarly, the punching base 51 is provided with a plurality of punching holes 510 corresponding to the positions of the punching punches. Specifically, the contour of the punching hole 510 is adapted to the contour of the punching punch 71, and the bottom of the punching hole 510 passes through the lower template 4 and the lower die base 1, thereby enabling the stamped waste to be discharged from the bottom.

[0026] In this embodiment, during the trimming process, in order to keep the metal product connected to the metal plate, it is necessary to trim both sides of the metal product separately. In order to ensure that no stress deformation occurs, the two sides are trimmed several times, and the trimming punch 72 is divided into a left trimming punch 721 and a right trimming punch 722. The left and right trimming punches 721 and 722 are arranged in sequence according to the unit length of a metal product along the conveying direction of the metal plate. Similarly, the trimming base 52 includes a left trimming hole 521 and a right trimming hole 522 corresponding to the positions of the left and right trimming punches 721 and 722. Specifically, the contours of the left and right trimming holes 521 and 522 correspond to the contours of the left and right trimming punches 721 and 722. The bottoms of the left and right trimming holes 521 and 522 pass through the lower template 4 and the lower die base 1, and the trimmed waste is discharged from the bottom.

[0027] Similarly, the bending punch 73 is installed with multiple bending times, and the multiple bending punches 73 are arranged in sequence along the conveying direction of the metal plate according to the unit length of a metal product, and the bending punch 73 near the conveying end and the cutting punch 74 are located within the unit length range of the same metal product. In this way, after the final bending process, it can be directly cut to form a single metal product, thereby improving production efficiency.

[0028] In this embodiment, in order to improve structural stability, the punching base 51 and the trimming base 52 are integrally formed to form a stamping plate 50 , and the plurality of punching holes 510 and the left and right trimming holes 521 and 522 are all provided on the stamping plate 50 .

[0029] In this embodiment, the upper template 6 is also provided with a clamping mechanism 8 for pressing the metal part on the conveying seat 5 during processing. The clamping mechanism 8 includes a plurality of sliding rods 81 movably connected to the upper template 6, a pressure plate 82 fixedly connected to the lower end of the sliding rod 81, and a return spring 83 sleeved on the sliding rod 81. The top of the sliding rod 81 passes through the upper template 6 and the upper die seat 3 upward and is limited by a nut or other limiting structure. The pressure plate 82 is provided with a through hole 820 corresponding to the contour of the punch head 7. The return spring 83 The top of the upper die plate 6 is against the bottom surface of the upper die plate 6, and the bottom of the return spring 83 is against the top surface of the pressure plate 82. During stamping, the upper die base 3 drives the pressure plate 82 to be pressed tightly against the metal plate, and the punching head 7 passes through the through hole 820 to punch and bend the metal plate. After the processing is completed, the return spring 83 drives the pressure plate 82 to continue to press down through the elastic force until the punching head 7 is separated from the metal plate, and the pressure plate 82 rises together with the upper die base 3. The clamping mechanism 8 can ensure that the metal plate remains stationary during the stamping process to avoid movement and affect the stamping accuracy.
