[0001] The invention relates to the field of thin-walled metal sleeve processing devices, and in particular to a thin-walled metal sleeve stamping and automatic feeding mechanism. Background Art

[0002] As the name implies, thin-walled metal casing is a tube made of metal material, which is 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 get the required products. Due to the small output in the early stage, each piece was inserted into the mold, stamped, and pulled out manually to achieve production. This efficiency is obviously relatively low.

The second frame plate 9 is provided with a through auxiliary discharge trough 11 near the bottom of the second inclined surface 10, and the diameter of the auxiliary discharge trough 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 trough 11 and pushes the thin-walled metal sleeve placed 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 column 24 to the stopper 25 and stably fix it on the plug column 24, thereby fixing the thin-walled metal sleeve on the rightmost side.

[0067] Embodiment 2: Based on Embodiment 1, a technical means is added to enable the device to continue to operate 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 a spline sleeve 38 for sliding movement 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 all fixedly connected to teeth 37, and the number of teeth 37 on the plurality of round blocks 36 increases in sequence from bottom to top. The outer wall of the spline sleeve 38 is connected to a bearing seat 35 for limited rotation. A second hydraulic cylinder 34 is fixedly installed 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 a second gear 40, and the second gear 40 can mesh 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 mesh with the second gear 40 .

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

[0071] There are twelve plug posts 24. There are three round blocks 36. The teeth 37 on the bottom round block 36 can drive the second gear 40 to rotate thirty degrees after rotating by a preset angle, the teeth 37 on the middle round block 36 can drive the second gear 40 to rotate sixty degrees after rotating by a preset angle, and the teeth 37 on the top round block 36 can drive the second gear 40 to rotate ninety degrees after rotating by a preset angle. That is, when all the plug posts 24 are normal, the teeth 37 on the bottom round block 36 are used to mesh with the second gear 40. When there is damage, the second gear 40 is first prevented from meshing with the teeth 37, the rotation angle of the first rotating column 39 is adjusted, and then the second gear 40 is adjusted to mesh with the corresponding teeth 37 according to the number distribution of the plug posts 24, so that the device can realize that after each plug post 24 rotates by a preset angle, the leftmost plug post 24 can be safely and stably loaded, the rightmost plug post 24 can be safely and stably fixed to punch materials, and the frontmost plug post 24 can be safely and stably unloaded.

[0072] That is, after the spline shaft 33 rotates by a preset angle, the first rotating column 39 and the disc 23 can be rotated by different angles. Then the second gear 40 is no longer meshed with the teeth 37, and the device is then automatically loaded, automatically punched, and automatically unloaded, and then returns to the initial position where the teeth 37 and the second gear 40 are initially meshed. At this time, the next cycle is performed, and the second hydraulic cylinder 34 is started to mesh the second gear 40 with the corresponding teeth 37. The motor 43 is continuously rotated forward to make the disc 23 continue to rotate by a preset angle, and the operation is repeated, so that the thin-walled metal sleeve is automatically loaded, automatically punched, and automatically unloaded.

[0073] The other structures are the same as those of 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 Fig.10 When the two elastic telescopic 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 detach from the frontmost plug 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 column 24, so that during stamping, the elastic telescopic impact plates 29 vibrate up and down to impact the outer wall of the plug column 24 to shake off the waste on the frontmost plug column 24.

[0076] Specifically, the elastic telescopic impact plate 29 includes a sliding sleeve 45, and an impact column 47 is slidably connected to the upper and lower limit positions in the sliding sleeve 45. An elastic member 46 is fixedly connected between the inner bottom of the sliding sleeve 45 and the impact column 47. The sliding sleeve 45 is fixedly installed on the connecting plate 28. When the two impact columns 47 push the thin-walled metal sleeve into the collecting trough 3, the two impact columns 47 are located at the top and bottom of the front end of the frontmost plug column 24. At this time, the punch head 6 punches the thin-walled metal sleeve on the far right, and the vibration force is transmitted to the elastic member 46 and the impact column 47 through the pressure column fixing plate 12 and the first rack 14. At this time, the elastic member 46 and the impact column 47 shake and hit the front end of the frontmost plug column 24, and the waste material on the plug column 24 is removed by vibration.

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

[0078] In this embodiment, it is first determined whether each plug post 24 is intact. If there is a plug post 24 that is not intact, the second hydraulic cylinder 34 is started so that the teeth 37 on different round blocks 36 mesh with the second gear 40, so that the disc 23 rotates to different preset angles and stops, and the damaged plug post 24 will not rotate to the leftmost, rightmost, or frontmost side of the disc 23. The device has multiple sets of redundant facilities, thereby improving the use efficiency of the device. It should be noted that this device is a preset simple control method and does not require complex program design.

[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] The motor 43 is started to make the spline shaft 33 rotate in the opposite direction. At this time, the spline shaft 33 drives the round block 36 and the corresponding teeth 37 to rotate. The second gear 40 is engaged with the teeth 37 to drive the disc 23 and the plug 24 to rotate forward to a preset angle. The second gear 40 is no longer engaged with the teeth 37. The disc 23 and the plug 24 remain stationary. At this time, the second hydraulic cylinder 34 is started again so that the round block 36 and the second gear 40 are not in the same plane, that is, no matter how the round block 36 rotates, the second gear 40 will not rotate. The transmission of the disc 23 is completed.

[0081] Then the spline shaft 33 continues to rotate in the opposite direction, at which time the incomplete gear 41 and the third gear 42 are meshed with each other, causing the first gear 27 to rotate, and the rotating first gear 27 is meshed 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 column 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 column 24, so that the thin-walled metal sleeve is sleeved on the outer wall of the leftmost plug column 24. The pressing column 13 presses the rightmost thin-walled metal sleeve onto the rightmost plug column 24.

[0083] At this time, the first rack 14 moving to the left drives the limit slide 31, the connecting plate 28, and the elastic telescopic impact plate 29 to move forward through the hinge rod 16, and the two elastic telescopic impact plates 29 push the thin-walled metal sleeve installed on the frontmost plug column 24 forward into the collecting trough 3. After the elastic telescopic impact plate 29 pushes the thin-walled metal sleeve out, the two elastic telescopic impact plates 29 are placed at the top front end of the frontmost plug column 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 telescopic impact plate 29. At this time, the elastic telescopic impact plate 29 moves up and down, and the elastic telescopic impact plate 29 hits the frontmost plug column 24, causing the waste on the plug column 24 to fall off.

[0084] Then the spline shaft 33 is started to rotate forward, so that the top column fixing plate 18 and the top column 19 move leftward, the pressure column 13 and the pressure column fixing plate 12 move rightward, and the elastic telescopic impact plate 29 moves backward. At this time, the thin-walled metal sleeve placed on the second inclined surface 10 continues to move downward, so that another thin-walled metal sleeve is placed at the lowest point of the second inclined surface 10. At this time, the spline shaft 33 rotates 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 started 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, so as to perform automatic loading, automatic stamping, and automatic unloading. That is, the material for automatic loading is moved to the automatic stamping position for stamping, and then after stamping is completed, it moves to the unloading position for automatic unloading.

[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.

[0087] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
