[0002] In the construction industry, metal profiles are widely used in key components such as frame construction and supporting structures due to their high strength and good stability. To meet different connection and assembly requirements, metal profiles often need to be punched. As one of the core pieces of equipment in the metal profile processing, the punching machine, through the cooperation of the punch and the stamping die, can process holes in the metal profile that meet the design requirements, so that the profiles can be assembled into a complete building structure using bolts, rivets and other connectors.

[0003] Traditional punching machines face challenges when dealing with diverse metal profile specifications. The process of changing stamping dies is cumbersome, often requiring multiple tools and a considerable amount of time for disassembly and installation. This makes it difficult to quickly switch dies to meet the punching requirements of different profiles, reducing overall processing efficiency. Furthermore, the punch, as a key component that directly performs the punching operation, is prone to wear or damage after long-term high-intensity use. The installation and replacement of traditional punches are inconvenient, increasing equipment maintenance costs and production downtime. Therefore, an automatic punching machine for building metal profiles is proposed to solve the above problems. Utility Model Content

A quick-release mechanism is installed in the middle of the platform 2, and a stamping die 14 is installed on the top of the quick-release mechanism. The structure enables quick installation and disassembly of the stamping die 14. The quick-release mechanism includes a locking component and an elastic component. The locking component includes a first insert 16 and a second insert 17. The second insert 17 is slidably connected to the outside of the first insert 16. The first insert 16 and the second insert 17 are slidably connected to the inside of the platform 2. The first insert 16 and the second insert 17 are engaged with the stamping die 14. The middle part of the stamping die 14 has a first slot 22 and a second slot 23. The first insert 16 and the second insert 17 are respectively engaged inside the first slot 22 and the second slot 23. A sliding plate 15 is fixedly connected to the outer side of the first insert 16, and the sliding plate 15 is slidably connected to the inside of the platform 2. The elastic component includes an outer rod 18, which is fixedly connected to the inside of the platform 2. An inner rod 24 is slidably connected inside the outer rod 18, and the inner rod 24 is fixedly connected to the outer side of the second insert 17. A spring 25 is installed inside the outer rod 18, and the inner rod 24 is located at the end of the spring 25. The first insert 16 and the second insert 17 are respectively engaged with the stamping die 14 through slot 1 22 and slot 2 23. The inner rod 24 is connected to the spring. 25 will apply an outward pushing force to the second insert 17, while the second insert 17 will apply an outward pushing force to the first insert 16, thereby stably engaging the first insert 16 and the second insert 17 in the slot 1 22 and the slot 2 23, thus fixing the stamping die 14 in place. After sliding the slide plate 15, the slide plate 15 will drive the first insert 16 to slide inward away from the slot 1 22, while the first insert 16 will then drive the second insert 17 to slide away from the slot 2 23, thereby releasing the engagement of the first insert 16 and the second insert 17, and the stamping die 14 can be disassembled.

[0012] Reference Figure 1 , Figure 6 and Figure 7The bottom of the mounting base 7 is fixedly connected to a snap-fit ​​connector 8 and a threaded tube 9. The threaded tube 9 is located on the outer periphery of the snap-fit ​​connector 8. Multiple clamping blocks 10 are fixedly connected to the bottom of the threaded tube 9. The top of the punch 11 is fixedly connected to a snap-fit ​​connector 12. The snap-fit ​​connector 12 and the snap-fit ​​connector 8 are snapped together. The outer side of the threaded tube 9 is threadedly connected to a threaded sleeve 13. The punch 11 is located in the middle of the threaded sleeve 13. After the punch 11 is placed in the middle of the threaded sleeve 13, the snap-fit ​​connector 12 is snapped into the snap-fit ​​connector 8. Then the threaded sleeve 13 is rotated, and the threaded sleeve 13 is tightened on the outside of the threaded tube 9 through the threads. When the threaded sleeve 13 is tightened, it will drive the clamping blocks 10 to clamp the punch 11, making the installation of the punch 11 more stable. The punch 11 can be removed by rotating the threaded sleeve 13 in the opposite direction, realizing the quick installation and removal of the punch 11. Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The pressing assembly includes a hydraulic cylinder 4, which is fixedly connected to the middle of the upright plate 3. The output end of the hydraulic cylinder 4 is fixedly connected to a pressure plate 5, and the mounting base 7 is fixedly connected to the bottom of the pressure plate 5. The hydraulic cylinder 4 provides downward pressure to drive the pressure plate 5 to press down, and the pressure plate 5 then drives the punch 11 to punch the metal profile. Multiple guide rods 6 are fixedly connected to the top of the frame 1. The other end of the guide rods 6 is fixedly connected to the outside of the upright plate 3, and the pressure plate 5 is slidably connected to the outside of the guide rods 6. The guide rods 6 provide guidance for the lifting and lowering of the pressure plate 5, so that it can press down accurately and stably. Multiple positioning blocks 19 are fixedly connected to the top of the table plate 2. Multiple positioning grooves 20 are opened at the bottom of the stamping die 14. The positioning blocks 19 are engaged in the inside of the positioning grooves 20. The positioning blocks 19 cooperate with the positioning grooves 20 to position the stamping die 14 on the table plate 2, ensuring that the stamping die 14 is installed in an accurate position. A sliding groove 21 is opened inside the table plate 2, and the sliding plate 15 is slidably connected inside the sliding groove 21.

[0013] Working principle: First, the positioning groove 20 at the bottom of the stamping die 14 is positioned by engaging with the positioning block 19 on the table 2. The inner rod 24 is pushed by the spring 25, causing the second insert 17 to engage with the second slot 23. The second insert 17 then pushes the first insert 16 to engage with the first slot 22. Through the elasticity of the spring 25 and the engagement of the first insert 16 and the second insert 17, the stamping die 14 is installed and fixed. The sliding plate 15 inside the sliding table 2 drives the first insert 16 to disengage from the first slot 22. The first insert 16 pulls the second insert 17 to compress the spring 25 and disengage it from the second slot 23, thereby releasing the engagement. The stamping die 14 can then be quickly removed, facilitating disassembly or replacement of the appropriate mold as needed.

[0014] After placing the punch 11 in the middle of the threaded sleeve 13, engage the clamping connector 12 with the clamping connector 8 of the mounting base 7. Then rotate the threaded sleeve 13, which is tightened onto the outside of the threaded tube 9 by the threads. At the same time, the clamping block 10 clamps the punch 11, thus achieving a stable installation of the punch 11. Rotating the threaded sleeve 13 in the opposite direction will release the clamping block 10, thereby quickly disassembling the punch 11. The hydraulic cylinder 4 drives the pressure plate 5 to press down along the guide rod 6. The pressure plate 5 drives the mounting base 7 and the punch 11 to move down synchronously, punching and drilling holes in the metal profile, thereby completing the punching process of the metal profile.
