Multi-station stamping technology has become a common method for mass production of precision sheet metal parts because it can achieve continuous processing. Quick mold change device is a key supporting structure for multi-station stamping equipment.

[0003] In the mass production of precision sheet metal parts, when it is necessary to switch between stamping dies of different specifications, the operator will activate the multi-station stamping quick die change device. Then, in coordination with the operating rhythm of the multi-station stamping equipment, the die change will be completed and the stamping processing of the new specification sheet metal parts can be carried out.

[0004] Existing mold-changing devices have significant shortcomings in practical use, making it difficult to adapt to molds of different sizes. Since different specifications of precision sheet metal parts require different sized molds for processing, and the mold-changing structure lacks flexible adjustment capabilities, each time a non-standard sized mold is changed, additional disassembly and installation of auxiliary components are necessary, significantly increasing operational complexity.

[0009] As a further description of the above technical solution: The inner wall of the press body is provided with a sliding groove, and the nut sleeve is slidably connected to the inner wall of the sliding groove through a lead screw.

[0010] As a further description of the above technical solution: The lead screw is provided in two sets, and the two sets of lead screws are arranged in a mirror symmetrical manner according to the center line of the placement plate.

[0011] As a further description of the above technical solution: The electric actuators are located at both ends of the mounting block and are arranged in a mirror-symmetrical manner according to the center line of the press body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a multi-station stamping quick mold change device for precision sheet metal parts, including a stamping machine body 1. A first motor 2 is fixedly connected to the outer wall of the stamping machine body 1. The first motor 2 can drive a bidirectional threaded rod 3 connected to its output end to rotate. When the bidirectional threaded rod 3 rotates, it can drive a threaded slider 4 threadedly connected to its outer wall to move along its axial direction. The threaded slider 4 is threadedly connected to the outer wall of the bidirectional threaded rod 3. The movement of the threaded slider 4 can synchronously drive a limiting rod 5 fixed to its outer surface to adjust its position. The limiting rod 5 is fixedly connected to the outer surface of the threaded slider 4. The outer wall of the limiting rod 5 is adapted to the inner wall of the mold opening, thereby achieving... For positioning and fixing molds of different sizes, the threaded slider 4 is slidably connected to the outer wall of the press body 1 through the bidirectional threaded rod 3. The inner wall of the press body 1 is fixedly connected to the electric push rod 6. The electric push rod 6 can push the mounting block 7 to move back and forth through the telescopic end. The telescopic end of the electric push rod 6 is fixedly connected to the mounting block 7. The rotating wheel 8 connected to the inner wall of the mounting block 7 can assist the mold to slide when it is placed, reduce the friction between the mold and the device and save manpower. The inner wall of the mounting block 7 is rotatably connected to the rotating wheel 8. The electric push rod 6 is set at both ends of the mounting block 7 and is set in a mirror symmetrical arrangement according to the center line of the press body 1. The symmetrical layout can ensure that the mounting block 7 is subjected to balanced force and improve the stability of the auxiliary mold movement. Reference Figure 1 , Figures 4-5A second motor 9 is fixedly connected to the bottom outer wall of the press body 1. The second motor 9 can drive the transmission screw 10 at the output end to rotate. The output end of the second motor 9 is fixedly connected to the transmission screw 10. The rotation of the transmission screw 10 can drive the worm gear 11 meshing on the outer wall to rotate synchronously. The outer wall of the transmission screw 10 is meshed with the worm gear 11. The outer wall of the lead screw 12 meshes with the outer wall of the worm gear 11. The rotation of the worm gear 11 can drive the lead screw 12 to rotate accordingly. The inner wall of the press body 1 is rotatably connected to the lead screw 12. The rotation of the lead screw 12 can drive the nut sleeve 13 meshing on the outer wall to move along its axial direction. The outer wall of the lead screw 12 is meshed with the nut sleeve 13. The inner wall of the stamping machine body 1 has a sliding groove 15 for the nut sleeve 13. The sliding groove 15 can guide and limit the movement of the nut sleeve 13. The nut sleeve 13 is slidably connected to the inner wall of the sliding groove 15 through the lead screw 12. The movement of the nut sleeve 13 can drive the placement plate 14 fixed on the outer wall to move synchronously, realizing the mechanical conveying and placement of the mold, avoiding the risk of manual handling. The outer wall of the nut sleeve 13 is fixedly connected to the placement plate 14. There are two sets of lead screws 12. The two sets of lead screws 12 are mirror-symmetrically arranged according to the center line of the placement plate 14. The symmetrical arrangement of the lead screws 12 can ensure that the force is uniform and the operation is stable when the placement plate 14 moves.

[0020] Working principle: The second motor 9 starts and drives the transmission screw 10 at the output end to rotate. The transmission screw 10 drives the worm gear 11 meshing with the outer wall to rotate synchronously. The worm gear 11 drives the lead screw 12 to rotate. The rotation of the lead screw 12 causes the nut sleeve 13 meshing with the outer wall to move axially along the lead screw 12 under the guide limit of the slide groove 15 on the inner wall of the stamping machine body 1. The nut sleeve 13 drives the placement plate 14 fixed on the outer wall to move synchronously to realize the mechanical transport of the mold. The two sets of lead screws 12 symmetrically arranged according to the branch line in the placement plate 14 ensure that the force is uniform and the operation is stable when the placement plate 14 moves. At the same time, the electric push rod 6 on the inner wall of the stamping machine body 1 starts and pushes the mounting block 7 to move back and forth through the telescopic end. The rotating wheel 8 connected to the inner wall of the mounting block 7 rotates during the mold placement process. The auxiliary mold slides, reducing friction between the mold and the device and saving manpower. The electric push rod 6 is set at both ends of the mounting block 7 and is symmetrically arranged according to the center line of the stamping machine body 1, which can ensure that the mounting block 7 is subjected to balanced force and improve auxiliary stability. After the mold moves to the designated position, the first motor 2 starts to drive the bidirectional threaded rod 3 at the output end to rotate. The bidirectional threaded rod 3 drives the threaded slider 4 connected to the outer wall to move along its axial direction. The threaded slider 4 simultaneously drives the limit rod 5 fixed on the outer surface to adjust its position. The adaptability of the limit rod 5 to the mold opening is used to achieve the positioning and fixing of molds of different sizes. The threaded slider 4 slides on the outer wall of the stamping machine body 1 through the bidirectional threaded rod 3 to ensure that the limit rod 5 is adjusted accurately, and finally completes the preparation for quick mold replacement.
