[0002] As the name suggests, thin-walled metal casing is a tube made of metal material, used to connect or protect other facilities such as wires, cables and important pipelines. This kind of casing can be made of different metal materials, the most common ones are steel pipe, aluminum pipe and copper pipe.

[0003] Sometimes we need to stamp the outer wall of thin-walled metal sleeves to produce the desired product. Due to low production volumes in the early days, we manually inserted each piece into the mold, stamped it, and then removed it. This was significantly inefficient.

[0048] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0049] Example 1:

[0050] Key References Figure 1-4 , 11, 12, 13, the device mainly includes a disc 23, a chassis 1, and a chassis support plate 2.

The top of the first rotating column 39 is fixedly connected to the bottom axis of the disk 23. Twelve plug-in columns 24 are evenly distributed on the outer circumference of the disk 23, or other plug-in columns 24 can be arranged at equal angular intervals on the outer circumference of the disk 23, and the number should be no less than twelve.

[0053] Key References Figure 5The plug 24 is provided with an auxiliary punching groove 26 for assisting the subsequent punching. The outer wall of the plug 24 is fixedly connected with a stopper 25 on both sides to limit the insertion of the thin-walled metal sleeve to the deepest position of the outer wall of the plug 24.

[0054] The top of chassis 1 is fixedly connected to a spline shaft 33 for limited rotation. The outer wall of spline shaft 33 is connected to a spline sleeve 38 for limited sliding movement up and down. The outer wall of spline sleeve 38 is fixedly connected to a round block 36. The outer wall of round block 36 is provided with teeth 37, and a second gear 40 can mesh with teeth 37. A second hydraulic cylinder 34 is fixedly mounted on chassis 1. The outer wall of spline sleeve 38 is connected to a bearing seat 35 for limited rotation. The telescopic end of second hydraulic cylinder 34 is fixedly connected to bearing seat 35. Note that the second embodiment differs from the arrangement here, and multiple round blocks 36 are provided in the second embodiment.

[0055] It should be noted that the second hydraulic cylinder 34 can control the second gear 40 to mesh with the teeth 37 , or can control the second gear 40 to not mesh with the teeth 37 .

[0056] A partial gear 41 is fixedly connected to the top of the spline shaft 33 .

[0057] Key References Figure 9 A motor 43 is fixedly installed at the bottom of the chassis 1, and the power output end of the motor 43 is connected to the spline shaft 33.

[0058] Key References Figure 8 and Figure 6 The top of the chassis 1 is connected to the second rotating column 44 for limited rotation. The outer wall of the second rotating column 44 is fixedly connected to the third gear 42. The third gear 42 can engage with the incomplete gear 41. The top of the second rotating column 44 is fixedly connected to the first gear 27.

[0059] Key References Figure 1 and Figure 6 The top of the chassis 1 is fixedly connected to multiple support seats 17, and the tops of the multiple support seats 17 are fixedly connected to the first limiting slide rail 15 and the second slide rail 21. The top of the first limiting slide rail 15 is slidingly connected to the first rack 14 in a left and right limited manner. The top of the right side of the first rack 14 is fixedly connected to the pressure column fixing plate 12, and the left side of the pressure column fixing plate 12 is fixedly connected to the pressure column 13; the top of the second slide rail 21 is slidingly connected to the second rack 20 in a left and right limited manner. The left side of the second rack 20 is fixedly connected to the top column fixing plate 18, and the right side of the top column fixing plate 18 is fixedly connected to the top column 19; the second rack 20 and the first rack 14 are respectively arranged on the front and rear sides of the first gear 27, and the second rack 20 and the first rack 14 are meshed with the first gear 27. When the second rotating column 44 rotates, it drives the top column fixing plate 18 and the top column 19 to move to the right for automatic loading, and the pressure column fixing plate 12 and the pressure column 13 move to the left to fix the material for stamping.

[0060] Key References Figure 8 The teeth on the incomplete gear 41 and the teeth 37 on the round block 36 are located in the same direction. The second rotating column 44 and the first rotating column 39 are placed on both sides of the spline shaft 33. When the spline shaft 33 rotates to drive the first rotating column 39 to rotate, the second rotating column 44 does not rotate. When the spline shaft 33 rotates to drive the second rotating column 44 to rotate, the first rotating column 39 does not rotate. This achieves intermittent control of the first rotating column 39 and the second rotating column 44 in time-sharing operation, causing the plunger 24 to swing to a preset angle and then stop. Then, the plunger 24 on the left side is automatically loaded, and the plunger 24 on the right side is used to fix the material for stamping. This ensures that the second rotating column 44 and the first rotating column 39 do not conflict, allowing for safe automatic loading, automatic stamping, and automatic unloading.

[0061] Key References Figure 1 and Figure 2 The top of the frame plate fixing plate 22 is fixedly connected to the second frame plate 9. The top of the second frame plate 9 is provided with a second inclined surface 10, which slopes downward from the back to the front. The second frame plate 9 is provided with an auxiliary discharge chute 11 near the bottom of the second inclined surface 10. The diameter of the auxiliary discharge chute 11 is slightly larger than the diameter of the thin-walled metal sleeve. When the top column 19 moves to the right, the top column 19 penetrates the auxiliary discharge chute 11 and pushes the thin-walled metal sleeve at the lowest position to the outer wall of the leftmost plug column 24, thereby completing the automatic loading of the thin-walled metal sleeve.

[0062] Key References Figure 1 The pressure column 13 moves to the left to push the thin-walled metal sleeve on the rightmost plug-in column 24 to the stopper 25 and stably fix it on the plug-in column 24, thereby fixing the thin-walled metal sleeve on the rightmost side.

[0063] A first hydraulic cylinder 7 is fixedly mounted on the hydraulic cylinder fixing seat 8, and a punching head 6 is fixedly mounted on the telescopic end of the first hydraulic cylinder 7. The punching head 6 is placed directly above the auxiliary punching groove 26 of the rightmost plug column 24, and is used to punch the thin-walled metal sleeve sleeved on the outer wall of the rightmost plug column 24, thereby completing the automatic punching of the thin-walled metal sleeve.

[0064] Key References Figure 2 、 Figure 7 and Figure 10A third limit slide rail 30 is fixedly connected to the top of the chassis 1, and the front and rear limit sliding connections on the third limit slide rail 30 are limited to the limit slide bar 31. A hinged rod 16 is hinged between the limit slide bar 31 and the first rack 14, which is used to drive the limit slide bar 31 to move forward when the first rack 14 moves to the left. The front side of the limit slide bar 31 is fixedly connected to an auxiliary plate 32, and the rear side of the auxiliary plate 32 is fixedly connected to two connecting plates 28. The two connecting plates 28 are fixedly connected to an elastic retractable impact plate 29 on the side close to each other away from the auxiliary plate 32. The two elastic retractable impact plates 29 are placed on the rear side of the stop block 25. When the two elastic retractable impact plates 29 move forward, they can drive the thin-walled metal sleeve sleeved on the outer wall of the front side plug column 24 to move forward and disengage from the front side plug column 24, thereby completing the stamping of the completed thin-walled metal sleeve and automatically removing it after stamping.

[0065] The first frame plate 5 is placed at the bottom of the frontmost plug column 24. A first inclined surface 4 is provided on the top of the first frame plate 5, and a collecting trough 3 is provided at the bottom of the first inclined surface 4 for collecting the finished thin-walled metal sleeves.

[0066] The above structure realizes automatic loading, automatic material fixing, automatic punching, automatic unloading and automatic material conveying.

[0067] Embodiment 2: Based on embodiment 1, a technical means is added to enable the device to continue operating when one or more of the plug posts 24 are damaged.

[0068] Key References Figure 8 The outer wall of the spline shaft 33 is connected to the spline sleeve 38 for sliding in the upper and lower limit positions. The outer wall of the spline sleeve 38 is fixedly connected to a plurality of round blocks 36 from top to bottom. The outer walls of the plurality of round blocks 36 are fixedly connected to teeth 37, and the number of teeth 37 on the plurality of round blocks 36 increases equally from bottom to top. The outer wall of the spline sleeve 38 is connected to the bearing seat 35 for limited rotation. A second hydraulic cylinder 34 is fixedly mounted on the chassis 1. The telescopic end of the second hydraulic cylinder 34 is connected to the bearing seat 35. The outer wall of the first rotating column 39 is fixedly connected to the second gear 40, and the second gear 40 can engage with the teeth 37 on one of the plurality of round blocks 36.

[0069] When one or more of the plug posts 24 are found to be damaged, the second hydraulic cylinder 34 can be moved up and down so that the teeth 37 on different round blocks 36 engage with the second gear 40 .

[0070] For a clearer presentation, a specific embodiment is described in detail.

[0071] There are twelve pins 24 and three circular blocks 36. The teeth 37 on the bottommost circular block 36 rotate through a preset angle, driving the second gear 40 to rotate thirty degrees. The teeth 37 on the middle circular block 36 rotate through a preset angle, driving the second gear 40 to rotate sixty degrees. The teeth 37 on the topmost circular block 36 rotate through a preset angle, driving the second gear 40 to rotate ninety degrees. That is, when all pins 24 are functioning properly, the teeth 37 on the bottommost circular block 36 mesh with the second gear 40. If any of the pins 24 are damaged, the second gear 40 is first disengaged from the teeth 37. The rotation angle of the first rotating column 39 is then adjusted. Then, based on the number of pins 24, the second gear 40 is adjusted to mesh with the corresponding teeth 37. This allows the device to ensure that, after each pin 24 rotates through a preset angle, the leftmost pin 24 safely and stably loads the material, the rightmost pin 24 safely and stably secures the material for stamping, and the frontmost pin 24 safely and stably unloads the material.

[0072] That is, after the spline shaft 33 rotates through a preset angle, the first rotating column 39 and the disc 23 can be rotated through different angles. This causes the second gear 40 to no longer mesh with the teeth 37, allowing the device to automatically load, stamp, and unload materials. The device then returns to its initial position, where the teeth 37 and the second gear 40 initially mesh. The next cycle then begins, activating the second hydraulic cylinder 34 to engage the second gear 40 with the corresponding teeth 37. The motor 43 continues to rotate forward, causing the disc 23 to continue rotating through the preset angle. This process repeats, allowing the thin-walled metal sleeve to be automatically loaded, stamped, and unloaded.

[0073] The other structures are the same as those in the first embodiment.

[0074] Embodiment 3: Based on embodiment 2, a technical means is added to facilitate the removal of waste materials on the plug posts 24 after unloading.

[0075] Key References Figure 7 and Figure 10 When the two elastic telescopic impact plates 29 move forward, they can drive the thin-walled metal sleeve on the outer wall of the front side plug-in column 24 to move forward and separate from the frontmost plug-in column 24, and when the two elastic telescopic impact plates 29 move forward to the frontmost side, they are placed on the front end top and bottom of the frontmost plug-in column 24, so that when stamping, the elastic telescopic impact plates 29 vibrate up and down to hit the outer wall of the plug-in column 24 to shake off the waste on the frontmost plug-in column 24.

[0076] Specifically, the elastically retractable impact plate 29 includes a sliding sleeve 45, within which an impact post 47 is slidably connected with upper and lower limits. An elastic member 46 is fixedly connected between the inner bottom of the sliding sleeve 45 and the impact post 47. The sliding sleeve 45 is fixedly mounted on the connecting plate 28. When the two impact posts 47 push the thin-walled metal sleeve into the hopper 3, the two impact posts 47 are located at the top and bottom of the front end of the frontmost plug post 24. At this time, the punch head 6 is punching the thin-walled metal sleeve on the far right. At this time, the vibration force is transmitted to the elastic member 46 and impact post 47 through the pressure post fixing plate 12 and the first rack 14. At this time, the elastic member 46 and impact post 47 shake and strike the front end of the frontmost plug post 24, vibrating and removing the waste material on the plug post 24.

[0077] The other structures are the same as those in the second embodiment.

[0078] In this embodiment, the integrity of each pin 24 is first determined. If any pin 24 is defective, the second hydraulic cylinder 34 is activated, causing the teeth 37 on different round blocks 36 to engage with the second gear 40, causing the disc 23 to rotate and stop at different preset angles. A damaged pin 24 will not rotate to the leftmost, rightmost, or frontmost side of the disc 23. This provides multiple redundant features, thereby improving the device's efficiency. Note that this device uses a simple, pre-set control method and does not require complex programming.

[0079] During the specific operation, the thin-walled metal sleeve to be processed is first placed on the second inclined surface 10. Due to the rolling property of the thin-walled metal sleeve, the thin-walled metal sleeve will roll to the lowest position of the second inclined surface 10. At this time, multiple thin-walled metal sleeves are evenly distributed on the second inclined surface 10.

[0080] Starting the motor 43 causes the spline shaft 33 to rotate in the reverse direction. This then drives the circular segment 36 and the corresponding teeth 37 to rotate. The second gear 40 engages with the teeth 37, driving the disc 23 and the plug 24 to rotate forward to a predetermined angle. The second gear 40 no longer engages with the teeth 37, and the disc 23 and the plug 24 remain stationary. At this point, the second hydraulic cylinder 34 is activated again, so that the circular segment 36 and the second gear 40 are not aligned. That is, no matter how the circular segment 36 rotates, the second gear 40 does not rotate. This completes the transmission of the disc 23.

[0081] Then the spline shaft 33 continues to rotate in the opposite direction. At this time, the incomplete gear 41 and the third gear 42 are engaged with each other, causing the first gear 27 to rotate. The rotating first gear 27 is engaged with the second rack 20 and the first rack 14, driving the top column fixing plate 18, the top column 19, and the second rack 20 to move to the right, and also driving the pressure column fixing plate 12, the pressure column 13, and the first rack 14 to move to the left.

[0082] The top post 19 passes through the auxiliary discharge chute 11 and pushes the thin-walled metal sleeve at the bottom of the second inclined surface 10 to the outer wall of the leftmost plug post 24, so that the thin-walled metal sleeve is sleeved on the outer wall of the leftmost plug post 24. The pressing post 13 presses the rightmost thin-walled metal sleeve onto the rightmost plug post 24.

[0083] At this time, the first rack 14 moving to the left drives the limiting slide 31, the connecting plate 28, and the elastic and retractable impact plate 29 to move forward through the hinge rod 16. The two elastic and retractable impact plates 29 push the thin-walled metal sleeve installed on the frontmost plug post 24 forward into the collecting trough 3. After the elastic and retractable impact plates 29 push the thin-walled metal sleeve out, the two elastic and retractable impact plates 29 are placed at the top front end of the frontmost plug post 24. At this time, the first hydraulic cylinder 7 is started to drive the punch head 6 to punch the thin-walled metal sleeve on the far right. At this time, the vibration of the punching will be transmitted to the elastic and retractable impact plate 29. At this time, the elastic and retractable impact plate 29 moves up and down, and the elastic and retractable impact plate 29 hits the frontmost plug post 24, causing the waste material on the plug post 24 to fall off.

[0084] The spline shaft 33 is then started to rotate forward, causing the top column fixing plate 18 and the top column 19 to move leftward, the pressure column 13 and the pressure column fixing plate 12 to move rightward, and the elastically retractable impact plate 29 to move backward. At this time, the thin-walled metal sleeve placed on the second inclined surface 10 continues to move downward, so that the other thin-walled metal sleeve is placed at the lowest point of the second inclined surface 10. At this time, the spline shaft 33 is rotated forward to the initial position before the teeth 37 mesh with the second gear 40.

[0085] At this time, the second hydraulic cylinder 34 is activated so that the teeth 37 on the corresponding round block 36 mesh with the second gear 40, and the initial position is restored, so that the second gear 40 continues to rotate forward by a preset angle, so that the next plug 24 moves to the required position, thereby performing automatic loading, automatic stamping, and automatic unloading. That is, the automatically loaded material moves to the automatic stamping position for stamping, and then moves to the unloading position for automatic unloading after stamping is completed.

[0086] The above-mentioned actions are repeated so that the thin-walled metal sleeves on each plug post 24 are automatically loaded, automatically punched, and automatically unloaded, and the operation is continuous.
