[0023] In one embodiment of the present invention, reference Figure 1~Figure 2As shown, a flanging separation mechanism within a multi-station transfer die is provided, comprising an upper die assembly 100, a lower die assembly 200, and a drive assembly. The upper die assembly 100 is positioned above the lower die assembly 200, and the drive assembly is connected to the upper die assembly 100 to drive the upper die assembly 100 toward or away from the lower die assembly 200. The upper die assembly 100 includes an upper die base 110, an upper die forming block 120, a first drive block 130, a first elastic member 140, and a shearing punch 150. The upper die forming block 120 is located below the upper die base 110. A first elastic member 140 is disposed between the upper die base 110 and the upper die forming block 120, with both ends of the first elastic member 140 connected to the upper die base 110 and the upper die forming block 120, respectively. A first driving block 130 is disposed below the upper die base 110, and a shearing punch 150 is disposed on one side of the first driving block 130. A gap is provided in the upper die forming block 120 for the first driving block 130 and the shearing punch 150 to pass through. The lower die assembly 200 includes a lower die base 210, a shearing lower die 220, a slider 230, and a second elastic member 240. The cutting lower die 220 is set on the lower die base 210, the slider 230 is slidably set on the lower die base 210, and is located between the lower die base 210 and the cutting lower die 220, the second elastic member 240 is set between the slider 230 and the lower die base 210, and the two ends of the second elastic member 240 are respectively connected to one side of the slider 230 and one side of the lower die base 210, and a gap is provided on the cutting lower die 220 for the first driving block 130 to pass through. In this embodiment, the product is placed on the cutting lower die 220. When the driving assembly drives the upper die assembly 100 to move toward the lower die assembly 200, the upper die forming block 120 first abuts against the cutting lower die 220 to fix the product on the cutting lower die 220. At this time, the upper die base 110, the first driving block 130 and the cutting punch 150 continue to descend, the first elastic member 140 is compressed, the first driving block 130 passes through the upper die forming block 120 and the cutting lower die 220 and abuts against the slider 230, the cutting punch 150 cooperates with the cutting lower die 220 to cut the product, and the driving slider 230 is moved to the lower die base 210. The upper mold assembly 100 is driven by the first elastic member 140 and the second elastic member 240, and the upper mold assembly 100 is driven by the second elastic member 240. The upper mold assembly 100 is driven by ...

[0024] Specifically, refer to Figure 1~Figure 2As shown, the first driving block 130 is provided with a first inclined surface 131 on the side away from the cutting punch 150, and the slider 230 is provided with a lower mold forming block 231 corresponding to the upper mold forming block 120 on the end close to the second elastic member 240. The slider 230 is also provided with a first slope 232 corresponding to the first inclined surface 131. The first slope 232 is located on the side of the lower mold forming block 231 away from the second elastic member 240, and the first slope 232 is inclined upward toward the lower mold forming block 231. In this embodiment, during the descending process of the upper mold base 110, the first driving block 130 is driven to descend, so that the first inclined surface 131 and the first slope 232 abut against each other. During the descending process of the first driving block 130, the first inclined surface 131 and the first slope 232 slide and drive the slider 230 to squeeze the second elastic member 240, so that the slider 230 can move laterally. The lower mold forming block 231 on the slider 230 cooperates with the upper mold forming block 120 to flange the product on the cut lower mold 220. One stamping action completes the flanging and separation of the product, thereby improving production efficiency.

[0025] Specifically, refer to Figure 1~Figure 2 As shown, the slider 230 is further provided with a waste chute 233, the opening of which faces below the cut-off punch 150. The waste chute 233 extends through the slider 230 to the outside of the lower die base 210, and the chute extends downward away from the cut-off punch 150. In this embodiment, the waste chute 233 is located below the cut-off punch 150. When the cut-off punch 150 cooperates with the cut-off lower die 220 to cut the product, the waste material falls into the waste chute 233 due to its own gravity and the impact force exerted by the cut-off punch 150 on the waste material. The waste material slides out of the lower die base 210 along the waste chute 233, preventing the waste material from remaining in the lower die base 210 and affecting the processing.

[0026] Specifically, refer to Figure 1~Figure 2 As shown, the upper die assembly 100 further includes a second driving block 160, which is disposed on one side of the upper die holder 110 and has a second inclined surface 161 thereon. A second slope 234 corresponding to the second inclined surface 161 is disposed on the slider 230. The second driving block 160 is located on one side of the upper die forming block 120 and the cutting lower die 220. In this embodiment, the second inclined surface 161 and the second slope 234 of the second driving block 160 cooperate with each other. As the upper die holder 110 descends, the second driving block 160 is driven downward, causing the second inclined surface 161 and the second slope 234 to abut against each other. As the second driving block 160 descends, the second inclined surface 161 and the second slope 234 slide and drive the slider 230 to squeeze the second elastic member 240. The second driving block 160 and the first driving block 130 simultaneously drive the slider 230 to move laterally, ensuring more uniform force on the slider 230 and smoother movement.

[0027] Specifically, refer to Figure 1~Figure 2 As shown, the cutting lower die 220 includes a placement portion 221 and a punching groove 222. The placement portion 221 is used to support the product, and the punching groove 222 is provided in and passes through the placement portion 221. The punching groove 222 is located between the cutting punch 150 and the waste chute 233. In this embodiment, the product is placed on the placement portion 221 and fixed, and the punching groove 222 cooperates with the cutting punch 150 to cut the product.

[0028] Specifically, refer to Figure 1~Figure 2 As shown, the cutting lower die 220 further includes a bearing portion 223, which is located on one side of the placement portion 221. The upper die forming block 120 is provided with a forming portion 121 at one end near the lower die forming block 231. The bearing portion 223 is located between the forming portion 121 and the lower die forming block 231, and the bearing portion 223 is provided with a forming chute 224 for the lower die forming block 231 to pass through. In this embodiment, as the upper die holder 110 descends, the slider 230 moves laterally, and the lower die forming block 231 passes through the forming chute 224 and cooperates with the forming portion 121 to flange the product. This allows the product to be flanged and separated in one stamping action, thereby improving production efficiency.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
