[0028] Implementation list:

[0029] As attached Figure 1-6 shown

[0030] This invention provides an automated multi-stage stamping and integral forming device for the production of automotive air conditioning mufflers, comprising a workbench 1, a workbench 2 19, and a robotic arm 30. The workbench 1 is fixedly mounted with a forming core, a lower semi-circular die base 3, and a feed limiter. A first stamping mechanism is fixedly mounted on the workbench 1 via a frame 2, driving the upper semi-circular die base 18 and the cutter 17 to move towards the lower semi-circular die base 3. During this movement, the cutter 17 cuts the material 6 used in the production of the automotive air conditioning muffler. The cut material 6 is then stamped into a U-shape between the upper semi-circular die base 18 and the forming column 10. After being stamped into a U-shape, the forming column 10 descends along with the upper semi-circular die base 18, causing the U-shaped material 6 to be further processed between the upper semi-circular die base 18 and the lower semi-circular die base 3. The tube is formed by stamping. The output end of the first stamping mechanism is detachably and fixedly equipped with an upper semi-circular mold base 18 and a cutter 17. The worktable 1 and the worktable 2 are detachably and fixedly connected by a connecting seat 29 so as to adjust the distance between the worktable 1 and the worktable 2. The robot arm 30 is fixedly installed on the connecting seat 29 so as to remove the stamped tube material 6 from the forming column 10 and place it into the mold locking mechanism. The mold locking mechanism and the second stamping mechanism are fixedly installed on the worktable 2. The mold locking mechanism locks the tube material 6. Then, the end of the tube material 6 is stamped and compressed by the reducing mold 28 at one end of the second stamping mechanism. The output end of the second stamping mechanism is detachably and fixedly equipped with a reducing mold 28.

[0031] Specifically, the molding core includes a T-shaped guide rail 7, a slide block 8, and a molding column 10. The T-shaped guide rail 7 is fixedly installed on the inner side of the connection between the worktable 1 and the frame 2. One end of the slide block 8 is slidably connected to the T-shaped guide rail 7 to ensure the stability of the molding column 10 during its up-and-down movement and to prevent the molding column 10 from shifting. The front end of the slide block 8 is detachably fixedly connected to one end of the molding column 10. The molding column 10 is located between the lower semi-circular mold base 3 and the upper semi-circular mold base 18. Two hydraulic rods are fixedly installed at the bottom of the slide block 8. 11. By setting the hydraulic rod 11, the stability of the forming column 10 is ensured when the cutter 17 cuts the material 6, so as to provide corresponding cutting support and preliminary forming support for the material 6. After the material is initially stamped into a U-shape, the forming column 10 follows the upper semi-circular mold base 18 down, so that the upper semi-circular mold base 18 and the lower semi-circular mold base 3 can be closed, and the material 6 can be stamped into a tube. The hydraulic rod 11 is fixedly installed in the worktable 1, and the output end of the hydraulic rod 11 slides out from the worktable 1.

[0032] Specifically, the mold-locking mechanism includes a hydraulic cylinder 22 and an electric rotary table 23. The hydraulic cylinder 22 is fixedly installed on the workbench 19 via a frame 20. The output end of the hydraulic cylinder 22 extends from below the frame 20. The output end of the hydraulic cylinder 22 is detachably and fixedly installed with an upper semi-circular locking mold 25, so that the upper semi-circular locking mold 25 can be driven by the hydraulic cylinder 22 to close with the lower semi-circular locking mold 24, thereby locking the material 6 stamped into a tubular shape. The electric rotary table 23 is fixedly installed on the workbench 19. The output end of the electric rotary table 23 is detachably and fixedly installed with a lower semi-circular locking mold 24 corresponding to the upper semi-circular locking mold 25. With the setting of the electric rotary table 23, the lower semi-circular locking mold 24 can be rotated, thereby adjusting the port of the tubular material 6 by 360 degrees.

[0033] Specifically, the feed limiter includes a feed seat 4 for use with an automatic feeding device for the material 6 used in the production of external automotive air conditioning mufflers. The feed seat 4 is fixedly installed on the workbench 1. The feed seat 4 has a feed limiting cavity 5 for conveying the material 6 through it, so as to limit the material 6 and ensure the accuracy and stability of the material 6 during the conveying process. The feed seat 4 is on one side of the lower semi-circular mold base 3. The feed limiting cavity 5 is located above the forming column 10.

[0034] Specifically, the first stamping mechanism includes a hydraulic cylinder 14, which drives the upper semi-circular die base 18 and the cutter 17 to move to one side of the lower semi-circular die base 3. The hydraulic cylinder 14 is fixedly mounted on the frame 2, and the output end of the hydraulic cylinder 14 extends out of the frame 2. The output end of the hydraulic cylinder 14 is fixedly mounted on the upper die base 15 to ensure the stability of the upper semi-circular die base 18. Each of the four corners of the upper surface of the upper die base 15 is fixedly mounted with a positioning post 16. The top end of the positioning post 16 slides out of the frame 2 to ensure the stability and accuracy of the upper die base 15 during operation. The upper semi-circular die base 18 is detachably fixedly mounted on the upper die base 15.

[0035] Specifically, the second stamping mechanism includes a support plate 21 and a hydraulic cylinder 26. The support plate 21 is fixedly installed on one side above the workbench 19. The hydraulic cylinder 26 is fixedly installed on the support plate 21 by a fixing seat 27 so that the reducing die 28 is driven by the hydraulic cylinder 26 to stamp and reduce the opening of the tubular material 6 in the upper semi-circular locking die 25 and the lower semi-circular locking die 24. The reducing die 28 is detachably fixedly installed on the output end of the hydraulic cylinder 26. The output end of the hydraulic cylinder 26 faces the lower semi-circular locking die 24 and the upper semi-circular locking die 25.

[0036] Specifically, a human-machine interface control system 31 is detachably and fixedly installed on one side of the frame 2 so as to control the automated multi-stage stamping integrated molding device for the production of automotive air conditioning mufflers through the human-machine interface control system 31. It should be noted that the controller inside the human-machine interface control system 31 adopts existing technology, such as the PLC in the existing technology, so it will not be described in detail here.

[0037] All the hydraulic cylinders involved in this case are connected to an external hydraulic pump station.

[0038] In this embodiment, when stamping the automotive air conditioning muffler, the material 6 is fed into the feeding limit cavity 5 through an external automatic feeding device until it reaches the required length. Then, the feeding stops and the forming column 10 is raised by the hydraulic rod 11 so that the forming column 10 contacts the material 6 and supports the material 6, thus completing the feeding.

[0039] The forming column 10 remains stationary, while the upper semi-circular mold base 18 and the cutter 17 are driven by the hydraulic cylinder 14 to move to the side of the lower semi-circular mold base 3. During the movement, the cutter 17 will cut the material 6, and the cut material 6 will be initially stamped between the upper semi-circular mold base 18 and the forming column 10 until the material 6 is stamped into a U-shape, completing one stamping.

[0040] After the material 6 is stamped into a U-shape, the hydraulic rod 11 drives the forming column 10 to move down with the upper semi-circular mold base 18 until the upper semi-circular mold base 18 and the lower semi-circular mold base 3 are closed. At this time, the U-shaped material 6 will be stamped into a tube between the upper semi-circular mold base 18 and the lower semi-circular mold base 3 and fitted onto the forming column 10 to complete the secondary stamping.

[0041] Separate the upper semi-circular mold base 18 and the forming column 10 from the lower semi-circular mold base 3. Then, use the robot arm 30 to remove the tubular material 6 from the forming column 10 and place it into the lower semi-circular locking mold 2, ensuring that the two ends of the tubular material 6 protrude from the two ends of the lower semi-circular locking mold 2 at the same length.

[0042] After the tubular material 6 is placed in the lower semicircular locking mold 2, the upper semicircular locking mold 25 and the lower semicircular locking mold 24 are closed by the hydraulic cylinder 22 to fix the tubular material 6.

[0043] After the tubular material 6 is clamped and fixed, one end of the reducing die 28 is driven by the hydraulic cylinder 26 to punch the reducing end, thus completing the port punching and forming the shape required for the automotive air conditioning muffler.

[0044] When the other end of the tubular material 6 also needs to be punched with a compression port, simply separate the upper semicircular locking mold 25 from the lower semicircular locking mold 24, and drive the lower semicircular locking mold 24 to rotate 360 ​​degrees through the electric rotary table 23, so that the other end of the tubular material 6 faces the constriction mold 28, and punch the compression port in the above manner.

[0045] Finally, the robotic arm 30 removes the molded car air conditioning muffler from the lower semi-circular locking mold 24 and places it into the corresponding collection container.

[0046] All components used in this application are standard parts, and the specific connection methods of each part adopt conventional methods such as threads, bolts, and nesting that are mature in the prior art. All structures use conventional materials in the prior art, and will not be described in detail here.

[0047] In summary, this automated multi-stage stamping integrated molding device for automotive air conditioning muffler production, through its overall design, can integrate multiple different processing modules of automotive air conditioning mufflers into one device, allowing the automotive air conditioning muffler to enter as raw material and exit in the required stamping form. This reduces the hassle of processing automotive air conditioning mufflers across multiple devices, thereby reducing wasted time.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
