Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] See also Figure 1 The utility model provides a stamping die, which is used for stamping a material strip 10 to form a plurality of sheets 11. The stamping die comprises an upper die unit 100, a lower die unit 200 and an elastic clamping device. The upper die unit 100 and the lower die unit 200 can be moved closer to or farther from each other. The elastic clamping device is installed on the lower die unit 200 and is used for guiding and elastically clamping each sheet 11.

[0034] It can be understood that, on the one hand, each sheet 11 can be restricted within the preset conveying track through the guiding ability of the elastic clamping device, and on the other hand, each sheet 11 can have a damping force during the conveying process within the conveying track through the elastic clamping ability of the elastic clamping device, so as to ensure the stable conveying of each sheet 11 within the conveying track. After providing a driving force to the sheet 11, two adjacent sheets 11 can abut against each other within the preset conveying track, so as to facilitate the continuous conveying of each sheet 11 within the preset conveying track, thereby improving the conveying efficiency of each sheet 11, and further improving the production efficiency of the stamping die.

[0035] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 7The stamping die also includes a cutter 500, which is installed on the upper die unit 100. The cutter 500 is used to cut the material strip 10 into a sheet 11, so that the elastic clamping device can guide and elastically clamp each sheet 11, and complete the stable and continuous conveyance of each sheet 11. Since the stamping die of this embodiment can cut the material strip 10 into multiple sheets 11, there is no need to set a connecting part, thereby improving the utilization rate of the material and reducing the cost of the sheet 11 product. At the same time, due to the setting of the elastic clamping device, the stable and continuous conveyance of each sheet 11 can also be guaranteed.

[0036] In one embodiment, see Figures 1 to 8 The elastic clamping device includes a first clamping module 300 and a second clamping module 400. The first clamping module 300 and the second clamping module 400 are symmetrically arranged on both sides of each sheet 11, and respectively guide and elastically clamp the two side edges of each sheet 11. Through the guiding effect of the first clamping module 300 and the second clamping module 400, each sheet 11 can be restricted within a preset conveying trajectory between the first clamping module 300 and the second clamping module 400, thereby facilitating the stable conveying of each sheet 11 within the preset conveying trajectory.

[0037] Further, in the present embodiment, the first clamping module 300 and the second clamping module 400 both include a first clamping plate 310, a second clamping plate 320 and a first elastic component 330, and the first elastic component 330 is installed on at least one of the first clamping plate 310 and the second clamping plate 320, so that the first clamping plate 310 and the second clamping plate 320 elastically clamp the material sheet 11. By such an arrangement, one side edge of each material sheet 11 can be aligned and clamped by the first clamping plate 310 and the second clamping plate 320 in the first clamping module 300, and the other side edge of each material sheet 11 can be aligned and clamped by the first clamping plate 310 and the second clamping plate 320 in the second clamping module 400.

[0038] Furthermore, in this embodiment, a guiding groove 321 is provided between the second clamping plate 320 and the first clamping plate 310, and the groove depth of the guiding groove 321 is not greater than the thickness of the sheet 11, so that the edge of each sheet 11 can be elastically clamped between the second clamping plate 320 and the first clamping plate 310. Preferably, the edge of the second clamping plate 320 close to the first clamping plate 310 is provided with a guiding groove 321, and the groove depth of the guiding groove 321 is less than the thickness of the sheet 11. It should be noted that, in this embodiment, the groove depth of the guiding groove 321 refers to the length dimension in the thickness direction of the sheet 11.

[0039] The groove wall of the guiding groove 321 is used to abut the side edge of each sheet 11, so as to guide the position of each sheet 11. Furthermore, the groove wall of the guiding groove 321 in the first clamping module 300 and the groove wall of the guiding groove 321 in the second clamping module 400 can guide each sheet 11 to be restricted within the conveying track between the first clamping module 300 and the second clamping module 400, thereby facilitating the stable and continuous conveying of each sheet 11.

[0040] Specifically, the groove wall of the guiding groove 321 is provided with a damping layer, and the surface of the first clamping plate 310 close to the guiding groove 321 is provided with a damping layer, so that the damping force of each sheet 11 during the conveying process in the conveying track is increased by the damping layer, so that the distance sent by the feeder is the same as the distance a single sheet 11 moves to the right, which is convenient for the stable and continuous conveying of each sheet 11. Specifically, the damping layer can be selected as a friction layer made of a rubber plate, or the damping layer can also be a friction surface formed on the wall surface of the guiding groove 321 and / or the surface of the first clamping plate 310. Of course, in other embodiments, the second clamping plate 320 close to the first clamping plate 310 can also be provided with a guiding column, and the height of the guiding column is smaller than the thickness of the sheet 11, so that the position of each sheet 11 is corrected by the guiding column.

[0041] In one embodiment, see Figure 7 As shown in Figure 8, the first elastic component 330 includes a connecting rod 331 and an elastic member 332. The first clamp plate 310 and the second clamp plate 320 are stacked. The first clamp plate 310 is provided with a first connecting hole 311, and the second clamp plate 320 is provided with a first through hole 322. The connecting rod 331 includes a head and a tail that are relatively arranged. The head of the connecting rod 331 passes through the first through hole 322 and is connected to the hole wall of the first connecting hole 311. The elastic member 332 is sleeved on the connecting rod 331 and elastically abuts between the second clamp plate 320 and the tail of the connecting rod 331, so that the first clamp plate 310 and the second clamp plate 320 can elastically clamp each sheet 11. In addition, by adjusting the elastic properties of the elastic member 332, the clamping force of the first clamping plate 310 and the second clamping plate 320 on each sheet 11 can be changed, thereby adjusting the damping force of each sheet 11 during transportation, so that a single sheet 11 can be smoothly fed and will not move to the right due to inertia, thereby ensuring the stable transportation of each sheet 11. In this embodiment, the first clamping plate 310 is stacked above the second clamping plate 320. Specifically, the connecting rod 331 can be a screw or a bolt.

[0042] Furthermore, a plurality of first elastic components 330 are provided, and are spaced apart on the first clamping plate 310 and the second clamping plate 320 along the conveying direction of each sheet 11, thereby ensuring the stability and reliability of the first clamping plate 310 and the second clamping plate 320 elastically clamping each sheet 11. Of course, in other embodiments, the first elastic component 330 may also be a tension spring, which elastically connects the first clamping plate 310 and the second clamping plate 320 and is used to pull the first clamping plate 310 and the second clamping plate 320 closer to each other, thereby achieving the first clamping plate 310 and the second clamping plate 320 elastically clamping each sheet 11.

[0043] In one embodiment, see Figures 4 to 8 The stamping die also includes a lifting device 600, which is installed on the lower mold unit 200 and connected to the elastic clamping device. The lifting device 600 is used to elastically support the elastic clamping device, so that after the upper mold unit 100 and the lower mold unit 200 are opened, the lifting device 600 can elastically support the elastic clamping device and each sheet 11 to float to a preset height.

[0044] In this embodiment, the elastic clamping device is provided with a mounting hole 301, and the ejecting device 600 includes a pressing plate 610, a ejecting column 620 and a second elastic component 630. The ejecting column 620 is passed through the mounting hole 301, and the pressing plate 610 is installed at the end of the ejecting column 620. The ejecting column 620 is provided with a ejecting surface 621 arranged opposite to the pressing plate 610. The elastic clamping device is limited to the space enclosed by the pressing plate 610 and the ejecting surface 621. The lower mold unit 200 is provided with a accommodating groove 210. The second elastic component 630 is installed in the accommodating groove 210 and is connected to the ejecting column 620.

[0045] Further, two ejection devices 600 are provided, and are respectively arranged in one-to-one correspondence with the first clamping module 300 and the second clamping module 400. In each ejection device 600, two ejection columns 620 and two second elastic components 630 are respectively provided, and are spaced apart on the first clamping plate 310 and the second clamping plate 320. Specifically, the ejection device 600 further includes a mounting member 640, which penetrates the pressing plate 610 and is connected to the end of the ejection column 620, so as to fix the pressing plate 610 to the end of the ejection column 620. Specifically, the mounting member 640 can be a screw or a bolt.

[0046] In one embodiment, the stamping die further includes an elastic support device, which is used to elastically support the material strip 10, so that the height of the cut-off point of the material strip 10 is the same as the preset height of the sheet 11. Further, the stamping die further includes a feeder, which is used to push the material strip 10 to move close to the elastic clamping device.

[0047] See also Figures 1 to 8, using the stamping die of the utility model, during the mold closing process, the upper mold unit 100 can be close to the lower mold unit 200, the upper mold unit 100 can abut the elastic clamping device against the accommodating groove 210 of the lower mold unit 200, the material strip 10 and each material sheet 11 are on the upper surface of the lower mold unit 200, the cutter 500 can cut the front section of the material strip 10 to form a material sheet 11, the elastic clamping device guides and elastically clamps the material sheet 11, and during the mold opening process, the upper mold unit 100 can be relatively close to the lower mold unit 200. The unit 200 moves away, and the material pusher 600 pushes the elastic clamping device to drive each material sheet 11 to float to a preset height. At the same time, the floating device pushes the supporting device to drive the material belt 10 to float to a preset height, so that the material belt 10 and each material sheet 11 are higher than the upper surface of the lower mold unit 200, and ensures that the front section of the material belt 10 and each material sheet 11 are at the same height. At this time, the feeder pushes the material belt 10 to move close to the elastic clamping device, and the material belt 10 can push each material sheet 11 to be transported in the elastic clamping device. When the material belt 10 is transported to the preset length, the above-mentioned mold closing and mold opening actions are repeated.

[0048] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention.
