Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In this embodiment, refer to Figures 1-8 The specific implementation of the continuous stamping forming die includes an upper die 1 and a lower die 2. The upper die 1 and the lower die 2 are respectively provided with guide sleeves and guide posts 25 that cooperate with each other. The lower end of the upper die 1 is provided with a blanking component 3 and a bending component 4. The lower die 2 is respectively provided with a blanking groove 21 and a bending groove 22 that cooperate with the blanking component 3 and the bending component 4. A detachable forming block 23 is provided in the bending groove 22. A pusher component 5 that cooperates with the forming block 23 is provided on one side of the bending groove 22. Limiting blocks 24 that cooperate with the pusher component 5 are provided on both sides of the forming block 23. Detachable guide posts 25 are provided on both sides of the blanking groove 21. A feeding component 6 that cooperates with the guide post 25 is provided on one side of the lower die 2.

[0025] The guide post 25 includes a post body 251 and limiting flanges 252 and threaded shafts 253 respectively located at both ends of the post body 251. The limiting flanges 252 extend outward along the outer side of the post body 251, and the lower die 2 has threaded holes corresponding to the threaded shafts 253. The arrangement of the post body 251 and the limiting flanges 252 allows the guide post 25 to restrict the movement direction of the stamped part 7 when it mates with the stamped part 7, preventing the stamped part 7 from shifting or warping during the stamping process, thereby improving the machining accuracy of the stamped part 7. In addition, the engagement of the threaded holes 26 and the threaded shafts 253 allows the guide post 25 to be stably and firmly installed on the lower die 2, and the height of the limiting flanges 252 can be adjusted by rotating the threaded shafts 253, thereby accommodating stamping materials of different thicknesses and enhancing the versatility and flexibility of the die.

[0026] The blanking assembly 3 includes a blanking block 31 and a pressure plate 32. The blanking block 31 is fixedly installed on the lower end of the upper die 1 by screws. The pressure plate 32 is slidably installed on the outside of the blanking block 31 via a sliding post 33. The pressure plate 32 is fixedly installed on one end of the sliding post 33, and the other end of the sliding post 33 is provided with a sliding block. The sliding block allows the sliding post 33 to drive the pressure plate 32 to slide within a small range. A compression spring 34 is sleeved on the outside of the sliding post 33, and the two ends of the compression spring 34 are respectively connected and cooperate with the upper die 1 and the pressure plate 32. Through the cooperation of the blanking block 31 and the blanking groove 21, the punching and cutting operations are completed, thereby improving the production efficiency of the stamped part 7. The setting of the sliding post 33 allows the pressure plate 32 to buffer when the stamped part 7 comes into contact, thereby avoiding excessive pressure on the stamped part 7 by the pressure plate 32, which could cause damage or deformation to the stamped part 7. When the mold closes, the pressure plate 32 first contacts the stamped part 7, and the compression spring 34 on the outside of the sliding column 33 causes the pressure plate 32 to pre-press the stamped part 7, so that the blanking block 31 can make more stable contact with the stamped part 7, avoiding deformation or damage to the stamped part 7 due to excessive instantaneous force, thereby improving the processing accuracy of the stamped part 7. When the mold opens, the compression spring 34 pushes the pressure plate 32 to reset through its own elasticity, so as to facilitate the next stamping operation.

[0027] The bending assembly 4 includes a base 41, a bending block 42, and a return spring 43. The base 41 is fixedly mounted to the lower end of the upper die 1 by screws. A mounting groove 411 is symmetrically arranged on one side of the base 41. The bending block 42 is rotatably mounted in the mounting groove 411 by the return spring 43. Fixing blocks 44 that cooperate with the bending block 42 are provided on both sides of the base 41. Fixing pins 45 that cooperate with the return spring 43 are provided on both sides of the base 41 and the bending block 42. Both the mounting groove 411 and the bending block 42 have an arc-shaped structure, allowing the bending block 42 to rotate within the mounting groove 411. The fixing blocks 44 and fixing pins 45 limit the movement of the bending block 42, preventing excessive rotation and preventing it from falling off during the stamping process. The reset spring 43 is set to reset the bending block 42. When the mold is closed, the bending block 42 cooperates with the forming block 23 to perform the bending operation of the stamping part 7. When the mold is opened, the reset spring 43 drives the bending block 42 to reset through its own elasticity, so that the fixing pin 45 contacts the fixing block 44 to facilitate the next stamping operation.

[0028] The ejector assembly 5 includes an ejector rod 51 and a drive component 52. The drive component 52 is fixedly installed on one side of the lower die 2, and the ejector rod 51 is located on the output end of the drive component 52. A sliding groove 26 that cooperates with the ejector rod 51 is provided through one side of the bending groove 22. Driven by the drive component 52, the ejector rod 51 reciprocates within the sliding groove 26. When the die is closed, the ejector rod 51 is in contact with the sliding groove 26, thereby avoiding interference between the ejector rod 51 and the stamped part 7. When the die is opened, the drive component 52 drives the ejector rod 51 to move forward within the sliding groove 26, pushing the cut stamped part 7 above the forming block 23 while simultaneously ejecting the bent stamped part 7 from the die, thus realizing continuous processing and automatic unloading of the stamped part 7.

[0029] The feeding assembly 6 includes a support base 61, an output roller 62, and a driven roller 63. The output roller 62 is fixedly mounted on the support base 61, and the driven roller 63 is slidably mounted on the support base 61. One end of the support base 61 is provided with a locking block 64 for fixing the driven roller 63. A quick-release buckle 65 is provided between the locking block 64 and the support base 61. The output roller 62 and the driven roller 63 are respectively provided with mutually meshing transmission gears 66. One end of the output roller 62 is connected to a rotary motor 67. Through the cooperation of the rotary motor 67 and the transmission gears 66, the output roller 62 and the driven roller 63 rotate synchronously, thereby pushing the stamping material into the mold for stamping processing. Both the output roller 62 and the driven roller 63 are fitted with detachable rubber sleeves. The rubber sleeves increase the friction between the output roller 62 and the driven roller 63 and the stamping material, thereby preventing the stamping material from slipping or deviating during the conveying process and ensuring that the stamping material can be accurately and stably conveyed into the mold. When the thickness of the stamped part 7 changes, only the rubber sleeve on the driven roller 63 needs to be replaced. This allows for the adaptation to stamped parts 7 of different thicknesses without affecting stable conveying, thereby improving the adaptability and flexibility of the mold. When it is necessary to replace the rubber sleeve, the locking block 64 can be quickly removed using the quick-release buckle 65, making the replacement of the rubber sleeve more convenient and faster.

[0030] The quick-release latch 65 includes a latch plate 651, a fixing plate 652, a lever block 653, and a locking buckle 654. The latch plate 651 is fixedly installed on both sides of the locking block 64, the fixing plate 652 is located on both sides of the support base 61, the lever block 653 is rotatably installed on the fixing plate 652, and the lever block 653 has a rotatable locking pin 655. A bolt 656 is installed on the locking pin 655, and the locking buckle 654 is rotatably installed on one end of the bolt 656. Through the cooperation of the latch plate 651 and the locking buckle 654, the locking block 64 can be quickly and firmly fixed to the support base 61. When it is necessary to remove the locking block 64, the lever block 653 is turned to separate the locking buckle 654 from the latch plate 651, and the locking block 64 can be removed from the support base 61, thus facilitating the replacement of the rubber sleeve. The rotatable locking pin 655 and the locking buckle 654 make the operation of the quick-release latch 65 more flexible and convenient. Furthermore, by rotating the bolt 656, the bolt 656 can be moved along the locking pin 655, thereby adjusting the extension distance of the latch 654 and thus adjusting the tightness of the fit between the latch 654 and the locking plate 651. This ensures the stability and reliability of the mold.

[0031] The beneficial effects of this invention are as follows: By cooperating with the blanking assembly 3 and bending assembly 4 in the blanking groove 21 and forming block 23 respectively, the mold can perform blanking and bending operations on sheet metal. Simultaneously, through the cooperation of the pusher assembly 5, limiting block 24, feeding assembly 6, and guide post 25, the mold can achieve automated loading and unloading and precise positioning, thereby improving production efficiency. Furthermore, the detachable forming block 23 and guide post 25 allow users to quickly replace and adjust them according to actual production needs, meeting the production requirements of parts of different sizes, thus enhancing the flexibility and practicality of the mold.
