[0027] A cylinder 9 is arranged directly above the forming box 4, and the output end of the cylinder 9 faces downward and is connected to a knife seat 13, on which a cutting knife 14 is installed, and the cutting knife 14 penetrates the forming box 4 and extends into the forming cavity 16, and a pad 17 is arranged inside the forming box 4 corresponding to the cutting knife 14, and a groove 18 is opened in the middle of the upper surface of the pad 17 corresponding to the cutting knife 14, and the groove 18 is in a "V" shape. When the cutting knife 14 enters the forming cavity 16, the cutting knife 14 will extend into the groove 18 of the pad 17, thereby completing the accurate cutting of the ultra-thin-walled metal strip;

[0028] A guide rod 11 is installed on one side of the forming box 4 near the discharge hole 12, and side brackets 1 are installed on both sides of the forming box 4. A base 2 is installed at the bottom of the discharge side plate 3. The finished metal strip after forming and cutting is removed through the guide rod 11, and the finished products after the cycle are stacked for easy collection.

[0029] See also Figure 1 - Figure 3 As shown, the basic principle is as follows: after the processing of the ultra-thin-walled metal strip is completed, it enters the forming box 6 through the conveyor belt, wherein the metal strip is placed into the forming cavity 16 in a tangential entry manner and automatically bent and formed. When the end of the metal strip is aligned with the entry point, the entry is stopped, and the cutting knife 14 is used to complete the cutting of the metal strip after bending and forming, and then the push plate 8 immediately pushes the finished metal strip out of the discharge hole 12 for unloading; the conveyor belt continues to feed the metal strip into the forming cavity 16, and the continuous processing of the metal strip is completed in a reciprocating cycle, so that the ultra-thin-walled metal strip is continuously processed during the bending and forming process, and a damage-free processing with seamless connection between cutting and forming is formed;

[0030] The cutting action is as follows: after the ultra-thin-walled metal strip enters the forming cavity 16, it is cut and bent along the forming cavity 16. At this time, the end of the metal strip abuts against the inner side of the metal strip that has entered. At this time, the conveyor belt is stopped from continuing to feed and the cylinder 19 is started. The cylinder 19 drives the knife seat 13 and the cutting knife 14 to penetrate into the forming box 4. The cutting knife 14 completes the cutting of the abutting part of the metal strip, that is, a round ultra-thin-walled metal strip product is formed;

[0031] The unloading action is as follows: after the round finished product of the ultra-thin-walled metal strip is formed, the cutting knife 14 withdraws and the cylinder 10 is started. The cylinder 10 drives the push frame 7 and the push plate 8 to enter the forming cavity 16. The push plate 8 enters through the insertion hole 19 and is pushed onto the round strip. The round ultra-thin-walled metal strip is discharged through the discharge hole 12 under the pushing action of the push plate 8, and is further moved out through the guide rod 11 to complete the stacking.

The feeding rack 5 is arranged on one side of the feeding port of the forming box 4. The feeding rack 5 is provided with a guide pressing plate 6 above the feeding port. Two running wheels 15 are respectively arranged on the upper and lower sides of the outer end of the feeding rack 5. The bottom surface of the guide pressing plate 6 is tangent to the inner wall of the forming box 4. The center position between the two running wheels 15 is aligned with the feeding port.

[0034] See also Figure 1 - Figure 6 As shown, the ultra-thin-walled metal strip to be formed enters the feed rack 5 through the conveyor belt, the metal strip corresponds to the groove of the feed rack 5 and is pushed forward by the running wheels 15. When the metal strip runs to the guide plate 6 along with the running wheels 15, the metal strip enters the forming cavity 16 under the tangential guiding action of the guide plate 6, thereby completing the bending forming action in the above-mentioned embodiment 1;

[0035] Combining Example 1 and Example 2, the auxiliary feeding structure can be used to achieve stable feeding of ultra-thin-walled metal strips, and the bending forming structure and the synchronous cutting structure can be combined to achieve cutting and separation of the metal strips after forming, so that the ultra-thin-walled metal strips can be processed under continuous actions such as bending, cutting and unloading, thereby avoiding damage to the ultra-thin-walled metal strips during the entire processing process.
