Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to an upper die for stamping an electrode plate and a stamping equipment. Background Technology

[0002] In the critical production process of forming and stamping metal electrode plates, a rather tricky problem occasionally occurs—the phenomenon of sticking to the die. The phenomenon of sticking to the die refers to the abnormal adhesion between the metal electrode plate and the upper die during the stamping process.

[0003] When this sticking phenomenon occurs, it can lead to a series of adverse consequences. First, it easily causes product deformation. After the metal electrode plate has completed its preset shape in the mold and is ready to be formed, local sticking between the metal electrode plate and the upper mold can cause deformation, bending, and other defects as the product moves upward with the mold. These defects lead to the failure of the metal electrode plate. Once the product deformation exceeds the specified tolerance range, it can only be judged as a scrap product. This not only wastes raw materials but also increases production costs.

[0004] Meanwhile, product adhesion to the mold also causes numerous problems for operators. Because the product is stuck to the upper mold, operators need to spend more time and effort to remove it. They may need to use auxiliary tools to carefully separate the product from the upper mold, which undoubtedly increases the difficulty of removal. Moreover, the extended removal time directly affects the rhythm of the entire production process, significantly reducing the processing efficiency of metal plates. Furthermore, the product scrapping caused by the adhesion phenomenon and the difficulty in removal ultimately affect the overall yield of metal plates, adversely impacting the company's production quality and economic benefits. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides an upper die for stamping an electrode plate and a stamping equipment.

[0006] This utility model provides the following technical solution: An upper die for stamping metal electrodes is used to cooperate with the lower die of a stamping equipment to stamp metal electrodes. The upper die for stamping metal electrodes includes an upper die body and a push rod.

[0007] The upper die body is mounted on a stamping machine. The end face of the upper die body near the lower die is the upper stamping surface, and a telescopic groove is provided on the upper stamping surface. The push rod passes through the telescopic groove, and an elastic element is provided between the push rod and the bottom of the telescopic groove. The elastic force of the elastic element can drive a portion of the push rod to extend out of the slot of the telescopic groove.

[0008] As a further improvement to the above technical solution, the telescopic groove is composed of an installation section and a telescopic section connected together. The telescopic section is located close to the upper stamping surface, and the diameter of the installation section is larger than the diameter of the telescopic section. A limiting block is provided at the end of the push rod away from the upper stamping surface. The push rod passes through the telescopic section, and the limiting block is located in the installation section. The elastic element is located in the installation section and between the limiting block and the bottom of the installation section away from the telescopic section.

[0009] As a further improvement to the above technical solution, the end face of the upper mold body opposite to the upper stamping surface is provided with an adjustment port that communicates with the bottom of the groove of the mounting section, and a plug is installed on the adjustment port.

[0010] As a further improvement to the above technical solution, the plug is threaded through the adjustment port.

[0011] As a further improvement to the above technical solution, multiple telescopic grooves are provided on the upper stamping surface.

[0012] As a further improvement to the above technical solution, the opening positions of each of the expansion grooves on the upper stamping surface correspond to the edge position of the metal electrode plate or the waste area.

[0013] As a further improvement to the above technical solution, the elastic element is a spring.

[0014] As a further improvement to the above technical solution, the axis of the telescopic groove is perpendicular to the upper stamping surface.

[0015] As a further improvement to the above technical solution, the end periphery of the push rod near the upper stamping surface is provided with a rounded transition.

[0016] The present invention also provides a stamping device, including an upper die for stamping the electrode plate as described in any of the above.

[0017] Compared with related technologies, the beneficial effects of this utility model are: The electrode stamping upper die provided by this utility model has the following specific operating procedure when stamping metal electrodes using stamping equipment: Before starting the stamping operation, the operator must first place the metal electrode material to be processed on the support surface of the lower die; then, start the stamping equipment, driving the upper die body to move slowly downward, so that the upper stamping surface of the upper die body gradually approaches the support surface of the lower die. During this approaching process, the push rod on the upper stamping surface will first contact the surface of the material to be stamped from its protruding end, forming a stable contact state. As the upper stamping surface continues to move downward, the distance with the support surface of the lower die gradually decreases, and the push rod will be subjected to the reaction force from the material, thereby gradually compressing the elastic element in the expansion groove. This compression process is smooth and controllable until the push rod is completely retracted into the expansion groove. At this time, the push rod no longer exerts a direct pushing effect on the material, thus ensuring that the stamping equipment can smoothly and unimpededly stamp the metal electrode without interfering with the normal operation of the stamping process due to the presence of the push rod.

[0018] After the stamping process is complete, the upper die body needs to be gradually moved away from the lower die under the drive of the stamping equipment. During this moving away process, the previously compressed elastic element begins to exert its elastic force. The elastic element gradually returns to its original shape, pushing the push rod to slowly extend from the telescopic groove, and always keeping it pressing against the already processed metal electrode plate. This design avoids the metal electrode plate sticking and moving with the upper die body after stamping. Because if the metal electrode plate sticks to the upper die body, the operator will face great difficulties when demolding and removing the part later, which will not only require more time and effort, but may also damage the metal electrode plate due to improper operation.

[0019] The electrode stamping upper die of this invention, through the design of the push rod, effectively reduces the difficulty for operators to demold the metal electrode from the upper stamping surface of the stamping equipment, significantly improving the efficiency of the entire production process. Furthermore, through the above operation, the metal electrode can be completely detached from the upper stamping surface in the initial stage of stamping, which has multiple positive implications. On the one hand, it effectively prevents the metal electrode from suddenly falling and being damaged due to adhesion failure, reducing unnecessary material waste and production costs; on the other hand, it also prevents the metal electrode from deforming under gravity due to partial adhesion, ensuring the shape and dimensional accuracy of the metal electrode, thereby improving the yield rate of finished metal electrodes.

[0020] In summary, the electrode stamping upper die of this utility model, through its unique design and working mechanism, ensures the processing quality of metal electrode plates by the stamping equipment, and provides a strong guarantee for the production of metal electrode plates.

[0030] like Figure 1 As shown, an embodiment of this utility model provides an upper die for stamping a metal electrode plate, which is used to cooperate with the lower die of a stamping equipment to stamp a metal electrode plate 400. The upper die for stamping a metal electrode plate includes an upper die body 100 and a push rod 200.

[0031] The upper die body 100 is mounted on a stamping machine. The end face of the upper die body 100 near the lower die is an upper stamping surface 110. An expansion groove 120 is provided on the upper stamping surface 110. The push rod 200 passes through the expansion groove 120. An elastic element 300 is provided between the push rod 200 and the bottom of the expansion groove 120. The elastic force of the elastic element 300 can drive a portion of the push rod 200 to extend out of the opening of the expansion groove 120.

[0032] The electrode stamping upper die provided in this embodiment operates as follows when stamping a metal electrode 400 using a stamping equipment: Before starting the stamping operation, the operator places the metal electrode 400 material to be processed on the support surface of the lower die; then, the stamping equipment is started, driving the upper die body 100 to move slowly downwards, so that the upper stamping surface 110 of the upper die body 100 gradually approaches the support surface of the lower die. During this approaching process, the push rod 200 on the upper stamping surface 110 will first contact the surface of the material to be stamped from its protruding end, forming a stable contact state. As the upper stamping surface 110 continues to move downwards, the distance between it and the support surface of the lower die gradually decreases, and the push rod 200 will be subjected to the reaction force from the material, thereby gradually compressing the elastic element 300 in the telescopic groove 120. This compression process is smooth and controllable until the push rod 200 is completely retracted into the telescopic groove 120. At this point, the push rod 200 no longer exerts a direct pushing effect on the material, thus ensuring that the stamping equipment can smoothly and unobstructedly stamp the metal electrode plate 400 without interfering with the normal operation of the stamping process due to the presence of the push rod 200.

[0033] After the stamping process is completed, the upper die 100 needs to be gradually moved away from the lower die under the drive of the stamping equipment. During this moving away process, the previously compressed elastic element 300 begins to exert its elastic force. The elastic element 300 gradually returns to its original shape, pushing the push rod 200 to slowly extend from the telescopic groove 120, and always maintaining pressure on the already processed metal electrode plate 400. This design avoids the metal electrode plate 400 from sticking and moving with the upper die 100 after stamping. Because if the metal electrode plate 400 sticks to the upper die 100, the operator will face great difficulties when demolding and removing the part later, which will not only require more time and effort, but may also damage the metal electrode plate 400 due to improper operation.

[0034] In this embodiment, the design of the upper die for stamping the metal electrode 400, through the push rod 200, effectively reduces the difficulty for operators to demold the metal electrode 400 from the upper stamping surface 110 of the stamping equipment, significantly improving the efficiency of the entire production process. Furthermore, through the above operation, the metal electrode 400 can be completely detached from the upper stamping surface 110 at the initial stage of stamping completion. This measure has multiple positive implications. On the one hand, it effectively prevents the metal electrode 400 from suddenly falling and being damaged due to adhesive failure, reducing unnecessary material waste and production costs. On the other hand, it also prevents the metal electrode 400 from deforming under gravity due to partial adhesion, ensuring the shape and dimensional accuracy of the metal electrode 400, thereby improving the yield rate of the finished metal electrode 400.

[0035] In some specific embodiments, the telescopic groove 120 is composed of a mounting section 121 and a telescopic section 122 connected together. The telescopic section 122 is disposed close to the upper stamping surface 110, and the diameter of the mounting section 121 is larger than the diameter of the telescopic section 122. A limiting block 210 is provided at the end of the push rod 200 away from the upper stamping surface 110. The push rod 200 passes through the telescopic section 122, and the limiting block 210 is disposed within the mounting section 121. The diameter of the limiting block 210 is larger than... The diameter of the telescopic section 122; the elastic element 300 is disposed within the mounting section 121 and located between the limiting block 210 and the bottom of the mounting section 121 opposite to the telescopic section 122; the inner diameter of the telescopic section 122 is equal to or close to the diameter of the push rod 200. The main purpose of this size matching design is to precisely guide the telescopic movement of the push rod 200, ensuring that the push rod 200 can move stably along a predetermined direction during telescopic movement without deviation or wobbling. The mounting section 121 undertakes the important task of restricting the movement of the elastic element 300 and the limiting block 210. Since the limiting block 210 can only move within the mounting section 121, and the elastic element 300 is also restricted between the limiting block 210 and the bottom of the mounting section 121, the telescopic range of the push rod 200 is indirectly and strictly limited. Through this design, problems such as the push rod 200 detaching from the telescopic groove 120 can be effectively avoided. Once the push rod 200 disengages from the telescopic groove 120, it will not only affect the normal operation of the stamping process, but may also lead to serious consequences such as equipment damage. Therefore, this design ensures the reliability of this embodiment in actual use, and can stably and efficiently complete the stamping task of the metal electrode plate 400.

[0036] In some specific embodiments, the upper mold body 100 has an adjustment port 130 on the end face opposite to the upper stamping surface 110, which communicates with the bottom of the groove of the mounting section 121. A plug 140 is installed on the adjustment port 130. The material and specifications of the plug 140 are matched with the adjustment port 130, and it can be tightly installed on the adjustment port 130 to prevent impurities, dust and other contaminants from entering the expansion groove 120 during the stamping process, which would affect the normal operation of the push rod 200 and the elastic element 300.

[0037] The design of this adjustment port 130 greatly facilitates operators. In actual production, the push rod 200 and the elastic element 300 are vulnerable parts, and after prolonged use, they may experience wear and aging, requiring regular maintenance and replacement. Without this adjustment port 130, operators would need to disassemble the entire upper mold body 100 to operate the push rod 200 and elastic element 300 within the telescopic groove 120. This is not only time-consuming and laborious but may also cause unnecessary damage to other components of the upper mold body 100. With this adjustment port 130, operators only need to remove the plug 140 to directly inspect, maintain, and replace the push rod 200 and elastic element 300 within the telescopic groove 120 through the adjustment port 130.

[0038] In some specific embodiments, the plug 140 is threaded through the adjustment port 130. This threaded design has many advantages. It not only ensures that the plug 140 is tightly installed on the adjustment port 130, preventing the plug 140 from loosening and falling off due to vibration or other factors during the operation of the stamping equipment, thereby preventing impurities from entering the expansion groove 120 and affecting the operation of internal parts, but also provides convenience for subsequent adjustment of the elastic element 300.

[0039] Specifically, when the operator rotates the plug 140, the plug 140 moves along the threaded path within the adjusting port 130. Since the adjusting port 130 is connected to the mounting section 121, the plug 140 passes through the adjusting port 130 and enters the mounting section 121. The position of the plug 140 within the mounting section 121 is not fixed; its positional change plays a crucial role. Depending on the position of the plug 140 within the mounting section 121, it exerts varying degrees of compression on the elastic element 300 within the mounting section 121. When the plug 140 moves deeper into the mounting section 121, it compresses the elastic element 300, placing it under greater compression; conversely, when the plug 140 is rotated outward from the mounting section 121, the compression of the elastic element 300 decreases.

[0040] Different compression amounts of the elastic element 300 directly affect its force on the push rod 200. The greater the compression amount of the elastic element 300, the greater the initial elastic force it generates on the push rod 200. During the stamping process, as the push rod 200 extends and retracts, the elastic force of the elastic element 300 also changes accordingly, and this change in elastic force is also closely related to the initial compression amount. By adjusting the position of the plug 140 within the mounting section 121 to change the compression amount of the elastic element 300, the operator can precisely adjust the initial elastic force of the elastic element 300 on the push rod 200 and its subsequent changes.

[0041] In actual production, the adhesion difficulty of different batches or types of metal electrode plates 400 may vary. Some metal electrode plates 400 are made of softer materials with smooth surfaces, making them prone to adhesion to the upper mold body 100; while others are made of harder materials with rougher surfaces, resulting in less adhesion. This embodiment, through the design of adjusting the compression of the elastic element 300 using the plug 140, can effectively accommodate these metal electrode plates 400 with varying adhesion difficulties. When handling metal electrode plates 400 with higher adhesion difficulty, the operator can screw the plug 140 into the mounting section 121 to increase the compression of the elastic element 300, allowing the push rod 200 to obtain a greater initial elastic force, thereby more effectively preventing the metal electrode plate 400 from adhering to the upper mold body 100. When handling metal electrode plates 400 with lower adhesion difficulty, the plug 140 can be appropriately screwed out to reduce the compression of the elastic element 300. This flexible adjustment method ensures that this embodiment can function well in different production scenarios, greatly expanding its applicability.

[0042] like Figure 2 As shown, in some specific embodiments, the telescopic groove 120 has multiple openings on the upper stamping surface 110. In the actual stamping production process, after the stamping work is completed, the processed metal electrode plate 400 needs to be detached from the upper stamping surface 110. If only a single pushing action is used, uneven force may occur on the metal electrode plate 400. For example, near a single pushing point, the metal electrode plate 400 may be subjected to a large pushing force and quickly separate from the upper stamping surface 110, but in other areas far from the pushing point, due to the smaller force, the metal electrode plate 400 may still remain stuck to the upper stamping surface 110. This will not only cause the metal electrode plate 400 to deform during the demolding process, affecting its finished product quality, but also increase the difficulty and time of demolding.

[0043] In this embodiment, multiple telescopic grooves 120 are formed on the upper stamping surface 110, and each telescopic groove 120 is provided with a corresponding push rod 200. Multiple push rods 200 can simultaneously apply a pushing force to the stamped metal electrode plate 400 from multiple different positions. This multi-point pushing method ensures that the metal electrode plate 400 receives a relatively uniform force on all parts during the process of separating from the upper stamping surface 110. Just as applying force simultaneously at multiple support points to lift an object keeps it stable, the coordinated action of multiple push rods 200 can evenly separate the metal electrode plate 400 from the upper stamping surface 110, avoiding localized adhesion.

[0044] Furthermore, the simultaneous operation of multiple ejector pins 200 can further improve the demolding efficiency of the metal electrode plate 400. With a single ejector pin 200, it takes time to gradually overcome the adhesion between the metal electrode plate 400 and the upper stamping surface 110. However, with multiple ejector pins 200 exerting force simultaneously, this adhesion can be quickly broken, allowing the metal electrode plate 400 to detach from the upper stamping surface 110 more quickly. This not only shortens the demolding time of a single metal electrode plate 400 but also improves the efficiency of the entire production process, meeting the needs of large-scale production.

[0045] In some specific embodiments, the opening positions of each of the expansion grooves 120 on the upper stamping surface 110 correspond to the edge positions or scrap areas of the metal electrode plate 400, respectively. During the stamping process of the metal electrode plate 400, the metal electrode plate 400 typically has specific functional areas, which play a crucial role in the final performance and use effect of the metal electrode plate 400. These areas have strict requirements regarding surface flatness, dimensional accuracy, and structural integrity; damage to these areas may affect the performance of the metal electrode plate 400, causing it to malfunction.

[0046] The placement of the expansion groove 120 at a location corresponding to the edge or scrap area of ​​the metal electrode plate 400 is of significant importance. When the push rod 200 extends from the expansion groove 120 to push the stamped metal electrode plate 400, the pushing position, being at the edge or scrap area of ​​the metal electrode plate 400, avoids the functional areas of the metal electrode plate 400 as much as possible. The edge area of ​​the metal electrode plate 400 typically has a certain machining allowance or is not a critical functional part during subsequent processing and use; even if subjected to a certain degree of pushing force, it will not significantly affect the overall performance of the metal electrode plate 400. The scrap area, being the portion removed during stamping, is not part of the finished metal electrode plate 400; the force applied to it by the push rod 200 will not damage the quality of the metal electrode plate 400.

[0047] This design effectively prevents damage to the functional areas of the metal electrode plate 400 during the pushing process by the push rod 200. For example, if the push rod 200 pushes directly onto the functional area, excessive pushing force may cause scratches, dents, or other defects on the surface of the functional area, affecting its conductivity or chemical stability. Uneven distribution of pushing force may also alter the dimensions of the functional area, making it unable to meet design requirements. By placing the push position at the edge or waste area, these problems are fundamentally eliminated, thereby improving the processing quality of the metal electrode plate 400 and ensuring that the produced metal electrode plate 400 meets high-quality standards and can be stably and reliably applied in corresponding products.

[0048] In some specific embodiments, the elastic element 300 is a spring. Springs have obvious advantages: their raw materials are common, their manufacturing process is mature, and their cost is low, which can reduce the cost of large-scale production. The elastic coefficient can be precisely designed, and it can provide a stable and reliable elastic force during operation to ensure that the push rod 200 pushes accurately. Moreover, as long as the material and process meet the standards and the use does not exceed the limit, it can withstand frequent compression and release cycles, has a long service life, and reduces the frequency of equipment maintenance and replacement and downtime.

[0049] In some specific embodiments, the axis of the telescopic groove 120 is perpendicular to the upper stamping surface 110. In the actual stamping production process, after the stamping process is completed, the metal electrode plate 400 needs to be smoothly demolded from the upper stamping surface 110. At this time, the push rod 200 will move within the telescopic groove 120 and apply a force to the metal electrode plate 400. If the axial direction of the telescopic groove 120 is not perpendicular to the upper stamping surface 110, then when the push rod 200 pushes the metal electrode plate 400, it may cause the metal electrode plate 400 to be subjected to a lateral component force.

[0050] Metal electrode 400 typically has a certain length and width, but is relatively thin, resulting in limited bending stiffness. When subjected to a lateral force, the metal electrode 400 is prone to bending deformation. Bending not only affects its appearance, causing surface unevenness and dimensional deviations, but may also damage its internal structure, thus impacting its subsequent performance and lifespan.

[0051] By designing the axis of the telescopic groove 120 to be perpendicular to the upper stamping surface 110, it can be ensured that when the push rod 200 pushes the metal electrode plate 400, the force is applied in a direction perpendicular to the upper stamping surface 110. In this way, the metal electrode plate 400 will only be subjected to a vertically downward pushing force, and under the combined action of its own weight and the pushing force, it will move vertically away from the upper stamping surface 110 without any lateral movement. Without the influence of the lateral component force, the metal electrode plate 400 can maintain its straight state and avoid bending deformation.

[0052] This design is crucial for ensuring reliable demolding of the metal electrode 400 in this embodiment. Reliable demolding means that the metal electrode 400 can be completely and undamagedly removed from the upper stamping surface 110, guaranteeing the quality of the finished product. Simultaneously, it reduces the scrap rate caused by demolding problems, improves production efficiency, and lowers production costs.

[0053] In some specific embodiments, the end periphery of the push rod 200 near the upper stamping surface 110 is provided with an arc transition to reduce the damage caused by the push rod 200 to the metal electrode plate 400 when pushing it, thereby improving the reliability of this embodiment.

[0054] An embodiment of this utility model also provides a stamping device, including an upper die for stamping the electrode plate as described in the above embodiment. The upper die for stamping the electrode plate is used in conjunction with a corresponding lower die. The stamping device has all the beneficial effects of the upper die for stamping the electrode plate, which will not be described in detail here.
