[0033] Embodiment 1

As shown Figures 1 to 5 it includes an upper die assembly 1, a lower die assembly 2 and a floating material guiding assembly 3; the upper die assembly 1 includes an inserting knife 11 and a floating pressing column 12, and the inserting knife 11 is provided with a first inclined surface 111; the floating material guiding assembly 3 includes a symmetrically arranged first floating material guiding frame 31 and a second floating material guiding frame 32, the first floating material guiding frame 31 is provided with a first material guiding groove 311, the second floating material guiding frame 32 is provided with a second material guiding groove 321, and both sides of the strip 4 are respectively restricted in the first material guiding groove 311 and the second material guiding groove 321; the lower die assembly 2 includes a slider 21, a fixed block 22 and a first spring 23, the first spring 23 is arranged between the slider 21 and the fixed block 22, the slider 21 is provided with a second inclined surface 211, the first inclined surface 111 and the second inclined surface 211 cooperate, a feeding part 212 is arranged at the top of the slider 21, and a material stopping part 221 is arranged at the top of the fixed block 22.
[0036] Specifically, the thickness of the strip 4 is 0.05 mm. A number of feeding holes 41 are respectively arranged on both sides of the strip 4. The heights of the first material guiding groove 311 and the second material guiding groove 321 are both 0.1 mm, enabling the strip 4 to freely move forward under the restriction of the first material guiding groove 311 and the second material guiding groove 321. The upper die assembly 1 further includes an upper die base 13 and an upper clamping plate 14. A second spring 131 is arranged on the upper die base 13. The second spring 131 cooperates with the floating downward pressing column 12, and the second spring 131 drives the floating material guiding assembly 3 with a certain buffering elastic force acting on the floating downward pressing column 12. The first floating material guiding frame 31 is provided with a first leg 312 and a second leg 313. The second floating material guiding frame 32 is provided with a third leg 322 and a fourth leg 323. The lower die assembly 2 includes a lower die base 24 and a lower template 25. A first cavity 26 for accommodating the slider 21 and the fixed block 22 is arranged on the lower die base 24. Second cavities 27 for the first leg 312, the second leg 313, the third leg 322 and the fourth leg to lift and lower respectively are arranged on the lower die base 24, and a third spring 271 is arranged at the bottom of the second cavities 27.
[0037] The working principle of the ultra-thin strip feeding device is as follows. The feeding part 212 includes a first vertical surface 2121 and the first arc surface 2122. The first arc surface 2122 faces the reverse direction of the advancing direction of the strip 4. In this design, the first vertical surface 2121 is used to drive the strip 4 forward, while the first arc surface 2122 will not let the strip 4 retreat. The material stopping part 221 includes a second vertical surface 2211 and the second arc surface 2212. The second arc surface 2212 faces the reverse direction of the advancing direction of the strip 4. In this design, the second vertical surface 2211 is used to block the strip 4 from retreating and enables the strip 4 to slide along the arc surface of the second arc surface 2212 when advancing. See Figures 1 to 4 , Figure 3 is a schematic diagram of the open die state of the upper die assembly 1 and the lower die assembly 2, while Figure 4 is a schematic diagram of the closed state of the upper die assembly 1 and the lower die assembly 2. Four floating downward pressing columns 12 are arranged in this embodiment, and two inserting knives 11 are arranged. During the descending process of the upper die assembly 1, the first inclined surfaces 111 of the two inserting knives 11 first cooperate with the second inclined surfaces 211 of the slider 21. As the upper die assembly 1 continuously descends, the slider 21 is driven to move in the direction of the arrow shown in Figure 4 , the first spring 23 is compressed, and the slider 21 moves along Figure 4During the movement in the direction of the arrow shown, the first arc surface 2122 slides along the bottom of the strip 4 without driving the strip 4 to move backward, and the second vertical surface 2211 blocks the backward movement of the strip 4; after the first inclined surface 111 drives the slider 21 to move in place, the floating pressing column 12 presses down the first floating material guiding frame 31 and the second floating material guiding frame 32, that is, as the upper die assembly 1 further descends, the floating pressing column 12 drives the material guiding assembly 3 to move downward, so that the feeding holes 41 on both sides of the strip 4 are more deeply sleeved on the feeding member 212 and the material stopping member 221; when the upper die assembly 1 moves upward, the floating pressing column 12 first releases, and the material guiding assembly 3 moves upward under the drive of the third spring 271. The feeding holes 41 on both sides of the strip 4 are still sleeved on the feeding member 212 and the material stopping member 221, but the sleeving is relatively shallow. During the process of the separation of the first inclined surface 111 and the second inclined surface 211, under the action of the first spring 23, the slider 21 moves forward, that is, along Figure 3 the direction of the arrow shown, and then drives the feeding member 212 to move forward. The first vertical surface 2121 of the feeding member 212 drives the ultra-thin strip 4 to move forward by one pitch. Under the limitation of the first material guiding groove 311 and the second material guiding groove 321, the ultra-thin strip 4 will not warp, and the feeding efficiency is improved.
