Description

Technical Field

[0001] This utility model relates to the field of aluminum stamping and forming technology, specifically to an aluminum-plastic film stamping machine. Background Technology

[0002] Common square lithium batteries require the use of an aluminum-plastic film packaging shell with indentations to wrap and seal the lithium battery cells. Therefore, in the manufacturing process of lithium batteries, a stamping process is required to stamp the aluminum-plastic film raw material into a single packaging shell with indentations.

[0003] In existing aluminum-plastic film stamping machines, the aluminum material is placed on the lower die, and then the upper die descends to fit against the lower die. The aluminum material is then stamped using extrusion pressure. When the upper die is raised, because the aluminum material has been stamped, there is still extrusion pressure between it and the interior of the upper die. Therefore, the formed aluminum material may rise along with the upper die, causing inconvenience during the demolding process. To address this, we propose an aluminum-plastic film stamping machine. Utility Model Content

[0004] This invention provides an aluminum-plastic film punching machine, which has the advantage of ensuring that the adsorption holes always adsorb aluminum material and preventing the formed aluminum material from being retained in the forming cavity due to extrusion pressure, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: An aluminum-plastic film stamping machine is designed, including a processing platform. A lifting device is provided on the top of the processing platform, and an extrusion die base is installed below the lifting device. A forming cavity is provided in the middle of the lower part of the extrusion die base. A lower die base corresponding to the extrusion die base is provided above the processing platform. When the extrusion die base descends, the top of the lower die base is placed in the forming cavity and a forming gap is provided between the two. The lower die base is set on a second mounting plate, and the second mounting plate is set on a third mounting plate. The third mounting plate is installed on the processing platform. At least one adsorption hole is opened on the lower die base, penetrating its top and the second mounting plate. An adsorption cavity corresponding to the adsorption hole is provided on the top of the third mounting plate. An air extraction hole communicating with the adsorption cavity is provided on one side of the third mounting plate. The air extraction hole is connected to the adsorption device.

[0006] Preferably, the lifting device includes guide columns vertically arranged at the four corners of the top of the processing platform. The top of the guide columns is connected to the top seat. A telescopic mechanism is vertically installed in the middle of the top seat. The telescopic mechanism is vertically connected to the mounting seat below. The mounting seat has connecting arms at both ends and guide seats at both ends. The guide seats are slidably sleeved on the guide columns.

[0007] Preferably, a first mounting plate is installed on the top of the extrusion die base, and the first mounting plate is detachably connected to the bottom of the mounting base.

[0008] Preferably, it also includes a pressing plate, the pressing plate having a receiving cavity in the middle that matches the lower die base, the top of the lower die base being movably placed in the receiving cavity, the edge of the receiving cavity having a placement groove for placing aluminum material, the pressing plate having multiple guide openings symmetrically arranged on the edge, each guide opening having a movably arranged guide support shaft, the bottom of the guide support shaft being vertically arranged on the second mounting plate, multiple elastic support mechanisms being provided between the pressing plate and the second mounting plate, under the support of the elastic support mechanisms, the top of the lower die base being located below the placement groove, and the top of the guide support shaft extending above the pressing plate, a guide hole being provided below the extrusion die base with a position corresponding to the top of the guide support shaft, when the extrusion die base is placed on the pressing plate, the guide support shaft being placed in the guide hole.

[0009] Preferably, each elastic support mechanism includes a return spring, with multiple return springs symmetrically distributed around the lower mold base, and a pressing plate placed on top of each return spring.

[0010] Preferably, the bottom of the pressing plate and the top of the second mounting plate are respectively provided with limiting grooves corresponding to the position and the return spring, and the two ends of the return spring are placed in the limiting grooves.

[0011] Preferably, the processing platform is provided with support legs at the four corners of the bottom, and a control cabinet is provided under the processing platform. The control cabinet is equipped with a controller, which is connected to the adsorption device and the telescopic mechanism respectively.

[0012] Preferably, a switch connected to the controller is provided on one side of the processing platform.

[0013] Compared with the prior art, in use, the aluminum material is placed in the placement groove, and the extrusion mold base is controlled to descend, so that the extrusion mold base presses the pressing plate downward and moves downward, so that the lower mold base presses the aluminum material against the forming cavity to form it. During this process, the adsorption hole always adsorbs the aluminum material until the aluminum material is demolded from the forming cavity. Therefore, when the extrusion mold base is raised, the pressing plate is also returned to the initial position under the action of the return spring. At this time, the formed aluminum material can be located at the top of the lower mold base, and the aluminum material can be formed in one go. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 6 This utility model provides a technical solution: an aluminum-plastic film punching machine, including a processing platform 28, such as... Figure 1 As shown, support legs 13 are provided at the four corners of the bottom of the processing platform 28. A control cabinet 12 is also provided below the processing platform 28. The control cabinet 12 is connected to the support legs 13. A controller is provided inside the control cabinet 12. The controller is a host or a PLC logic controller, etc. A switch 14 connected to the controller is provided on one side of the processing platform 28.

[0025] The top of the processing platform 28 is equipped with a lifting device, such as... Figure 1 and Figure 2 As shown, the lifting device includes guide columns 15 vertically arranged at the four corners of the top of the processing platform 28, with the top of the guide columns 15 connected to the top seat 1. A telescopic mechanism 2 is vertically installed in the middle of the top seat 1. The telescopic mechanism 2 is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. In this application, the telescopic mechanism 2 is preferably a hydraulic cylinder, and the telescopic mechanism 2 is connected to a controller. Next, the telescopic mechanism 2 is vertically connected to the mounting base 3 below. Connecting arms 8 are provided at both ends of the mounting base 3, and guide seats 4 are provided at both ends of the connecting arms 8. The guide seats 4 are slidably sleeved on the guide columns 15. Linear bearings can be installed inside the guide seats 4 to reduce friction between them and the guide columns 15.

[0026] A pressing die base 7 is installed below the lifting device. Specifically, a first mounting plate 6 is installed on the top of the pressing die base 7. The first mounting plate 6 is detachably connected to the lower part of the mounting base 3. The first mounting plate 6 and the mounting base 3 are fastened together by bolts. A forming cavity 27 is provided in the middle of the lower part of the pressing die base 7. The forming cavity 27 matches the shape of the aluminum-plastic shell to be stamped.

[0027] Corresponding to the extrusion die holder 7 is, as Figure 1 As shown, a lower die holder 20 corresponding to the extrusion die holder 7 is provided above the processing platform 28. When the extrusion die holder 7 descends, the top of the lower die holder 20 is placed in the forming cavity 27 and there is a forming gap between the two. Because the aluminum material to be stamped is placed on the top of the lower die holder 20, when the extrusion die holder 7 descends and contacts the aluminum material, the top of the lower die holder 20 extrudes the aluminum material into the forming cavity 27 and forms it in the forming gap.

[0028] The lower mold base 20 is mounted on the second mounting plate 10, the second mounting plate 10 is mounted on the third mounting plate 11, the second mounting plate 10 and the third mounting plate 11 are fastened together by bolts, the third mounting plate 11 is mounted on the processing platform 28, and the third mounting plate 11 and the processing platform 28 are also fastened together by bolts, which facilitates disassembly and installation.

[0029] like Figure 3 and Figure 4 As shown, the lower mold base 20 has at least one adsorption hole 19 that penetrates its top and the second mounting plate 10. The top of the third mounting plate 11 has an adsorption cavity 23 corresponding to the adsorption hole 19. One side of the third mounting plate 11 has an air extraction hole 25 that communicates with the adsorption cavity 23. The air extraction hole 25 is connected to the adsorption device. The adsorption device is connected to the controller. The adsorption device includes a negative pressure pump connected to the controller. The negative pressure pump is connected to a pipe connector 24 through a conduit. The pipe connector 24 is threaded into the air extraction hole 25. When the adsorption device is working, the adsorption device will evacuate the adsorption cavity 23, thereby allowing the adsorption hole 19 to produce adsorption force. The adsorption device can be set in the control cabinet 12. It should be noted that the adsorption device is only activated during the extrusion and demolding process.

[0030] The specific process is as follows, such as Figure 6 As shown, when the lower mold base 20 presses the aluminum material against the forming cavity 27, due to the extrusion force between the forming cavity 27 and the aluminum material, the formed aluminum material may remain inside the forming cavity 27 and fall after the extrusion mold base 7 is raised. Therefore, during the extrusion process, the adsorption hole 19 always adsorbs the aluminum material. This not only prevents the aluminum material from shifting, but also ensures that the aluminum material stays on the top of the lower mold base 20 during the demolding process and does not remain inside the forming cavity 27 as the extrusion mold base 7 is raised.

[0031] Furthermore, to increase the stability of the aluminum material placed on top of the lower mold base 20, a pressing plate 9 is also provided above the second mounting plate 10, such as... Figure 3 and Figure 4 As shown, a receiving cavity 16 matching the lower mold base 20 is provided in the middle of the pressing plate 9. The top of the lower mold base 20 is movably placed in the receiving cavity 16. The edge of the receiving cavity 16 is provided with a placement groove 18 for placing aluminum material. That is, the aluminum material can be positioned by placing it in the placement groove 18.

[0032] The pressing plate 9 has multiple guide openings 17 symmetrically arranged along its edge. Each guide opening 17 contains a movable guide support shaft 5, the bottom of which is vertically mounted on the second mounting plate 10. Simultaneously, multiple elastic support mechanisms are provided between the pressing plate 9 and the second mounting plate 10. Each elastic support mechanism includes a return spring 21, which is symmetrically distributed around the lower mold base 20. The pressing plate 9 is positioned on top of each return spring 21. To ensure the stability of each return spring 21, limiting grooves 22 corresponding to the positions of the return springs 21 are provided at the bottom of the pressing plate 9 and the top of the second mounting plate 10, with both ends of the return springs 21 positioned within the limiting grooves 22.

[0033] Supported by the elastic support mechanism, the top of the lower mold base 20 is located below the placement groove 18, meaning the height of the top of the lower mold base 20 does not exceed the height of the bottom of the placement groove 18. Therefore, when aluminum material is placed in the placement groove 18, the aluminum material does not contact the top of the lower mold base 20 or just contacts it. Figure 1 As shown, at this time, the top of the guide support shaft 5 extends above the pressing plate 9, and then... Figure 5 As shown, a guide hole 26 is provided below the extrusion die holder 7, the position of which corresponds to the top of the guide support shaft 5. Figure 5 As shown, when the extrusion die 7 is placed on the pressing plate 9, the guide support shaft 5 is placed in the guide hole 26. At this time, the guide support shaft 5 can not only support the pressing plate 9 and prevent the pressing plate 9 from shifting, but also the top of the guide support shaft 5 can stabilize the up and down movement of the extrusion die 7, making the contact between the extrusion die 7 and the lower die 20 more stable.

[0034] It should be noted that, in order to prevent the return spring 21 from causing the pressing plate 9 to jump, the telescopic mechanism 2 drives the extrusion mold base 7 to move up and down at a constant speed, and the speed of movement is matched with the return speed of the return spring 21. In this way, when the extrusion mold base 7 leaves the pressing plate 9, the pressing plate 9 can come to a stop immediately.

[0035] Based on the above embodiments, further optimization is possible. When the switch 14 is pressed, the telescopic mechanism 2 can be controlled to extend and retract. To ensure operational safety, two switches 14 can be set on one side of the processing platform 28. The telescopic mechanism 2 can only be activated when both hands press the switch 14 at the same time, which can avoid the danger of placing both hands on the lower mold base 20.

[0036] Based on the above embodiments, it should be further explained that in the actual working process, the initial state is as follows: Figure 5 As shown, the extrusion die holder 7 rests above the lower die holder 20, and then the aluminum material is placed in the placement groove 18;

[0037] Then as Figure 6 As shown, the extrusion die 7 is controlled to descend, so that the extrusion die 7 presses against the pressing plate 9 and moves downward, while the lower die 20 will press the aluminum material into the forming cavity 27.

[0038] Finally, as Figure 7 As shown, when the extrusion die 7 is raised, the pressing plate 9 is also restored to its initial position under the action of the return spring 21, and the formed aluminum material can then be located on the top of the lower die 20.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
