Description

Technical Field

[0001] The invention relates to the technical field of battery grid processing and manufacturing, in particular to a continuous casting and laminating molding device for a multi-layer composite metal lead-acid battery grid. Background Art

[0002] In the field of electrochemical energy storage, lead-acid batteries play a key role, and their performance depends to a large extent on the quality of the grid. In the past, grids mostly adopted a single-layer structure of lead-antimony alloy or lead-calcium alloy, which was formed by gravity casting or die casting. However, this type of single alloy system has obvious disadvantages. Lead-antimony alloy can easily cause the negative electrode to accelerate self-discharge, and lead-calcium alloy will have interface microcracks in deep cycles, shortening the battery life. At the same time, the traditional casting process requires high-temperature operation, emits lead smoke to pollute the environment, and has low material utilization, resulting in high energy consumption and cost. In order to break through the performance bottleneck of a single material, the industry has turned to the research of multi-layer composite metal grids. By stacking different metal layers or adding non-metallic reinforcement layers, it is possible to take into account the needs of conductivity, corrosion resistance and lightweight. However, the current multi-layer grid manufacturing technology is full of difficulties. In the process of material strip alignment and pressing, the traditional manual or simple mechanical alignment has poor accuracy, and relies on the mechanical positioning method of hole-column matching. When thermal expansion or material strip deformation occurs, it is easy to cause layer deviation, resulting in increased resistance and uneven corrosion after pressing. Conventional pressing equipment is also unable to distribute pressure evenly and accurately. When faced with material strips of different thicknesses and materials, it is easy to have loose pressing and stratification, which seriously affects the stability of the grid structure. Summary of the invention

[0006] The present invention is further configured such that the size of the docking head is smaller than the size of the first docking hole, the size of the stamping head is adapted to the size of the first docking hole, and the size of the ejector rod is adapted to the size of the second docking hole.

[0007] The present invention is further configured such that an extrusion block two is provided at a position of the bottom of the fixed shell close to the extrusion block one. The extrusion block two is slidably connected with the extrusion block one and is used for jointly lifting the strip with the lifting component during the stamping process.

[0008] The present invention is further configured such that a first docking surface is provided at a position of the top of the activity block close to the docking groove. A pressing rod is provided at the bottom of the module two corresponding to the docking groove. The bottom of the pressing rod extends into the installation cavity through the docking groove.

[0009] The present invention is further configured such that the pressing rod is slidably connected with the inner wall of the docking groove. A first pressing surface is formed on the outer wall of the pressing rod close to the first docking surface. The first pressing surface is slidably connected with the first docking surface. The bottom of the pressing rod is connected with a second pressing block through a first spring. The second pressing block is slidably connected with the inner wall of the installation cavity. A second pressing surface is formed on the outer wall of the second pressing block close to the extrusion block two.

[0010] The present invention is further configured such that an extrusion groove is formed inside the top plate. An installation plate is fixedly connected to the lower surface of the pressing plate, and there are two groups of the installation plates symmetrically distributed on the lower surface of the pressing plate. Each group of the installation plates has two and is distributed at both ends of the extrusion groove.

[0012] Beneficial effects of the continuous casting and laminating forming device for the multi-layer composite metal lead-acid battery grid of the present invention: 1. When the upper die mechanism descends, the pressure rod squeezes the movable block through the pressing surface, and the movable block pushes the movable plate through the second spring, driving the top plate to contact the material tape and push it to align. The top plate and the pressing plate cooperate to fix material tapes of different sizes and thicknesses, effectively preventing the material tape from moving or shifting horizontally during stamping, ensuring the accuracy of the stamping position, greatly improving the product size accuracy and consistency, significantly reducing the rejection rate. After the top plate contacts the material tape and cannot push it anymore, it drives the extrusion groove to squeeze the docking bolt, causing the pressing plate to fall and press both sides of the top of the material tape, which increases the stability of the material tape during stamping, avoids its shaking or warping, reduces problems such as stamping deformation and material shortage caused by instability, promotes better fitting of multi-layer material tapes, and under the subsequent heating and pressing, enhances the bonding strength of the multi-layer composite metal, improving the overall performance and service life of the grid. 2. During stamping, the top rod of the lifting assembly always supports the material tape with the docking head at its top. On the one hand, it can prevent the displacement or deformation of the material tape, improve the accuracy of the stamping position and product accuracy. On the other hand, it can make the material tape better withstand the pressure of the stamping head, avoid cracking or incomplete stamping caused by uneven local stress, improve the stamping quality, and ensure the integrity and firmness of the grid structure. At the same time, the docking head shares part of the pressure of the stamping head on the material tape, reduces the friction between the stamping head and the material tape, reduces the wear of the stamping head, extends the service life of the mold, and the uniform supporting force avoids excessive extrusion damage to the material tape, improves the utilization rate of the material tape, and reduces the production cost. 3. After stamping, the stamping head of the upper die mechanism inserts into the docking hole of the lower die mechanism, and the pressing block squeezes the extrusion block of the lower die mechanism, causing the top rod of the lifting assembly to extend, and the waste materials are pushed into the discharge cavity of the upper die mechanism through the docking head. The driving assembly in the discharge cavity drives the cleaning brush to clean the waste materials out, realizing efficient waste material cleaning, keeping the working area clean, and being conducive to improving production efficiency. 4. When the top rod pushes the waste materials out of the discharge cavity, the movable plate 1 drives the heating assembly to fit with the docking plate, and the heat is transferred to the material tape through the docking plate. At the same time, it is transmitted multi-directionally through the top rod and the stamping head, ensuring uniform heating of the material tape, ensuring the consistency of physical and chemical changes in each part during the pressing process, improving the quality stability of the product. The heating assembly is arranged in the movable plate 1 to avoid direct contact with components such as the upper die mechanism that are easily affected by high temperature, reducing the thermal damage of high temperature to the mold and mechanism, extending the service life of the mold and related components, reducing the equipment maintenance cost, and enhancing the reliability and stability of the production process.

[0019] Please refer to Figures 1 - 10 For a continuous casting and lamination forming device of a multi-layer composite metal lead-acid battery grid plate, it includes a lower die mechanism 1. The lower die mechanism 1 includes a main frame 11. There is an installation cavity 111 at the top of the main frame 11. A module one 12 is arranged inside the installation cavity 111. The module one 12 includes a jacking component 121 and a positioning component 122. The jacking component 121 includes a docking plate 1211 fixedly installed inside the installation cavity 111. An active plate one 1213 is slidably connected inside the docking plate 1211. A plurality of ejector rods 1214 are fixed to the top of the active plate one 1213. A docking head 12141 is provided at the top of each ejector rod 1214. A docking hole one 1212 is penetrated and opened at the position corresponding to the ejector rod 1214 on the top of the docking plate 1211. The positioning component 122 is arranged on both sides of the jacking component 121 for precisely positioning the strip. An upper die mechanism 2, which includes a positioning slide bar 212 fixedly connected to the top of the main frame 11. A module two 22 is slidably connected to the outer wall of the positioning slide bar 212. A stamping head 222 is provided at the bottom of the module two 22. A discharge cavity 221 is provided at the top of the module two 22. The top end of the stamping head 222 extends into the discharge cavity 221. A docking hole two 2221 is penetrated and opened at the position corresponding to the ejector rod 1214 at the bottom of the stamping head 222. The docking hole two 2221 is communicated with the discharge cavity 221.

[0020] By adopting the above technical solutions, the pressing surface one 2231 of the pressing rod 223 cooperates with the docking surface one 12231 of the movable block 1223 to align the strip. The spring one 224 buffers and transmits pressure. After stamping, the extrusion block three 225 extrudes the extrusion block two 1222 to eject the waste. The ejector rod 1214 of the jacking component 121 has a heating component 12142. After stamping, the active plate one 1213 drives it to fit with the docking plate 1211 to uniformly heat the strip, and at the same time avoids damaging other components due to high temperature. The driving component 2211 and the cleaning brush 2212 in the discharge cavity 221 can clean the waste after stamping.

[0021] A heating component 12142 is provided at the position of the active plate one 1213 close to the ejector rod 1214. The positioning component 122 includes a fixed shell 1221 fixedly installed inside the installation cavity 111. There is an active cavity 12211 inside the fixed shell 1221. Docking grooves 12212 communicated with the active cavity 12211 are symmetrically opened at the top and bottom of the fixed shell 1221. An active block 1223 and an active plate two 1224 are slidably connected inside the active cavity 12211. The top end of the active plate two 1224 extends to the outside of the fixed shell 1221 and is fixedly connected with a clamping plate 1226. A top plate 1227 and a pressing plate 1228 are respectively slidably connected inside the clamping plate 1226. The top plate 1227 and the pressing plate 1228 are respectively used for the preliminary alignment and pressing fixation of the strip.

[0022] By adopting the above technical solution, the heating component 12142 transfers heat in all directions to make the material strip heated more evenly on the entire contact surface, thereby ensuring the consistency of physical and chemical changes in various parts of the material strip during the pressing process. When the top plate 1227 contacts the material strip and cannot be pushed further, it will move closer to the clamping plate 1226. During this process, the top plate 1227 will drive the extrusion groove 12271 to move, and then squeeze the docking bolt 12282, and drive the pressing plate 1228 to fall by squeezing the docking bolt 12282. The pressing plate 1228 will fall and press on the top of the material strip, and press both sides of the material strip while clamping, thereby increasing the stability of the material strip during stamping, making it less likely to shake or warp when subjected to stamping pressure.

[0023] The size of the docking joint 12141 is smaller than that of the docking hole 1212, the size of the punching head 222 is matched with the size of the docking hole 1212, the size of the push rod 1214 is matched with the size of the docking hole 2221, and an extrusion block 1222 is provided at the bottom of the fixed shell 1221 near the extrusion block 1215. The extrusion block 1222 is slidably connected to the extrusion block 1215, and is used to cooperate with the lifting assembly 121 to lift the material belt during the stamping process. A cleaning brush 2212 is slidably connected inside the discharge chamber 221, and a driving assembly 2211 for driving the cleaning brush 2212 to move is also provided inside the discharge chamber 221, which is used to clean the waste material in the discharge chamber 221 after the stamping is completed.

[0024] By adopting the above technical scheme, the size of the docking joint 12141 is smaller than the docking hole 1212, and the insertion of the punch head 222 is not hindered during stamping, thereby ensuring smooth stamping action. The size of the punch head 222 and the docking hole 1212, as well as the size of the push rod 1214 and the docking hole 2221 are adapted to ensure accurate matching of various components and improve product dimensional accuracy. The extrusion block 2 1222 at the bottom of the fixed shell 1221 is slidably connected with the extrusion block 1 1215, and after stamping, the lifting assembly 121 is coordinated to make the push rod 1214 smoothly extend out to eject waste, thereby improving work efficiency.

[0025] A docking surface 12231 is provided at the top of the movable block 1223 near the docking groove 12212, a pressure rod 223 is provided at the bottom of the module 22 corresponding to the docking groove 12212, the bottom of the pressure rod 223 extends to the inside of the installation cavity 111 through the docking groove 12212, the pressure rod 223 is slidably connected to the inner wall of the docking groove 12212, a pressure surface 1231 is provided on the outer wall of the pressure rod 223 near the docking surface 12231, the pressure surface 12231 is slidably connected to the docking surface 12231, the bottom of the pressure rod 223 is connected to an extrusion block 3 225 through a spring 1 224, the extrusion block 3 225 is slidably connected to the inner wall of the installation cavity 111, and a pressure surface 2251 is provided on the outer wall of the extrusion block 3 225 near the extrusion block 2 1222.

[0026] By adopting the above technical solution, when the second module 22 drops, the pressure rod 223 extends into the installation cavity 111 through the docking groove 12212, and its first pressing surface 2231 pushes the first docking surface 12231, prompting the movable block 1223 to move within the movable cavity 12211, thereby driving the second movable plate 1224 to bring the top plate 1227 into contact with the material tape, achieving precise alignment, effectively overcoming the problem of poor alignment accuracy in the traditional method. In the later stage of stamping, after the first spring 224 is compressed to the limit, the second pressing surface 2251 of the third extrusion block 225 extrudes the second extrusion block 1222, cooperating with the first extrusion block 1215, enabling the ejector rod 1214 to smoothly extend to eject the waste material, improving the waste material cleaning efficiency, and ensuring the continuous and stable operation of the device.

[0027] An extrusion groove 12271 is formed inside the top plate 1227. The lower surface of the pressing plate 1228 is fixedly connected with mounting plates 12281. There are two groups of the mounting plates 12281 and they are symmetrically distributed on the lower surface of the pressing plate 1228. Each group of the mounting plates 12281 has two and they are distributed at both ends of the extrusion groove 12271. The inner side of one group of the mounting plates 12281 is fixedly connected with a docking bolt 12282 that slides on the inner wall of the extrusion groove 12271, which is used to drive the pressing plate 1228 to drop when the top plate 1227 moves. An activity rod 1225 is arranged on one side of the clamping plate 1226 close to the movable block 1223. One end of the activity rod 1225 penetrates through the movable block 1223 and is slidably connected. A second spring 12251 whose one end is connected to the movable block 1223 is sleeved outside the activity rod 1225.

[0028] By adopting the above technical solution, when the top plate 1227 is pushed by the second movable plate 1224 to contact the material tape and continues to move, the extrusion groove 12271 extrudes the docking bolt 12282, causing the pressing plate 1228 to quickly drop and press the material tape tightly, which can adapt to material tapes of different sizes and thicknesses, solve the problem that it is difficult for traditional pressing equipment to apply uniform and precise pressure, ensure that all layers of the material tape are tightly bonded. In the initial stage when the pressure rod 223 pushes the movable block 1223 to move, the second spring 12251 can absorb part of the impact force, ensuring the smooth movement of the movable block 1223, providing stable power for the accurate alignment of the top plate 1227 with the material tape, and thus ensuring the accuracy of the stamping position.

[0029] The working principle and usage process of the embodiment of the present invention: When the pressure rod 223 is in the normal state, the first pressing surface 2231 remains in contact with the first docking surface 12231, the first spring 224 is not compressed, and the second pressing surface 2251 remains in contact with the second extrusion block 1222. When the pressing plate 1228 is in the normal state, it is above the top plate 1227, and the docking bolt 12282 is also at the highest point of the extrusion groove 12271. A third spring 1229 whose one end is connected to the clamping plate 1226 is arranged at the bottom of the pressing plate 1228. The top of the positioning slide rod 212 is provided with a fixing plate 21, and a pushing component 211 whose output end is fixedly connected to the second module 22 is arranged on the top of the fixing plate 21.

[0030] In use, the strip is stacked by the conveying mechanism and then fed into the forming device. The strip is placed between the upper die mechanism 2 and the lower die mechanism 1 and on top of the lifting assembly 121. When the strip needs to be processed, the upper die mechanism 2 is pushed to start falling by the pushing assembly 211. When falling, it will first squeeze the docking surface 12231 through the first surface pressing part 2231. After the docking surface 12231 is squeezed, it will push the movable block 1223 to move inside the movable cavity 12211. When the movable block 1223 moves, it will push the second movable plate 1224 towards the strip through the second spring 12251. When the second movable plate 1224 approaches the strip, the top plate 1227 will contact the strip. By continuously pushing, the strip can be aligned, ensuring that the strip remains in a fixed position during stamping, preventing it from moving or shifting horizontally, making the stamping position accurate, ensuring the product size accuracy and consistency, and reducing the scrap rate.

[0031] When the top plate 1227 contacts the strip and cannot be pushed further, it will approach the clamping plate 1226. During this process, the top plate 1227 will drive the extrusion groove 12271 to move, thereby squeezing the docking bolt 12282. By squeezing the docking bolt 12282, the pressing plate 1228 is driven to fall. When the pressing plate 1228 falls, it will press on the top of the strip, pressing both sides of the strip while clamping, increasing the stability of the strip during stamping, making it not easy to shake or warp when bearing the stamping pressure. This helps improve the stamping quality, avoiding problems such as stamping deformation and material shortage caused by the instability of the strip, making the grid structure more uniform and complete, and also making the multi-layer strips fit together better during stamping. Under the subsequent action of heating and pressing, the combination between the strips is tighter, thereby improving the bonding strength of the multi-layer composite metal and enhancing the overall performance and service life of the grid. Moreover, strips of different sizes and thicknesses can be fixed. After the top plate 1227 and the pressing plate 1228 align and press the strip, since the force received exceeds its bearing capacity, the second spring 12251 is compressed. By compressing the second spring 12251, the movable block 1223 continues to move. When the pressing rod 223 falls, due to the existence of the first spring 224, it cannot directly act on the third extrusion block 225, which makes the pressing rod 223 unable to push the second extrusion block 1222 through the third extrusion block 225.

[0032] As the upper die mechanism 2 descends, it drives the stamping head 222 to stamp the strip. During stamping, the top end of the docking head 12141 always presses against the strip, providing support below the strip. This can effectively prevent the strip from shifting or deforming during stamping, making the stamping position more accurate, thereby improving the dimensional accuracy and consistency of the product. The supporting effect of the docking head 12141 enables the strip to better withstand the pressure of the stamping head 222 during stamping, avoiding the situation of the strip cracking or being incompletely stamped due to uneven local stress, which helps to improve the stamping quality and make the stamped grid structure more complete and firm. On the one hand, the docking head 12141 can share part of the pressure of the stamping head 222 on the strip, reducing the friction between the stamping head 222 and the strip, thereby reducing the wear of the stamping head 222 and extending the service life of the mold. On the other hand, the uniform supporting force can prevent the strip from being damaged due to excessive extrusion, improve the utilization rate of the strip, and reduce production costs.

[0033] With the completion of stamping, the stamping head 222 will insert into the inner part of the docking hole one 1212. At the same time, the first spring 224 has been compressed to the limit, and then it will squeeze the second extrusion block 1222 through the third extrusion block 225. The second extrusion block 1222 transfers the received extrusion to the first extrusion block 1215, so that the first extrusion block 1215 is squeezed and raised. The raising of the first extrusion block 1215 will drive the ejector rod 1214 to extend out of the docking hole one 1212 through the first movable plate 1213. At this time, the docking head 12141 will press against the stamped waste material, making it move inside the docking hole two 2221. The stamping head 222 continues to descend until the docking head 12141 pushes the waste material into the discharge cavity 221. Then, the driving component 2211 inside the discharge cavity 221 works, and the driving cleaning brush 2212 cleans the waste material out of the discharge cavity 221.

[0034] When the docking head 12141 enters the inner part of the discharge cavity 221, the fixed plate 21 will completely press on the strip. At the same time, the first movable plate 1213 will drive the heating component 12142 to fit with the docking plate 1211. The heating component 12142 transfers heat to the strip through the docking plate 1211. At the same time, the heat of the heating component 12142 will also be transferred to the stamping head 222 through the ejector rod 1214 and then to the strip through the stamping head 222. This multi-directional heat transfer method helps to make the strip heat more evenly on the entire contact surface, avoiding the situation of local overheating or overcooling, thereby ensuring the consistency of the physical and chemical changes of each part of the strip during the pressing process and improving the stability of the product quality. Setting the heating component 12142 in the first movable plate 1213 avoids the heating component 12142 directly contacting the upper die mechanism 2 or other components vulnerable to high temperature, reducing the thermal damage of high temperature to the mold and mechanism. This helps to extend the service life of the mold and related components, reduce the equipment maintenance cost, and at the same time improve the reliability and stability of the production process.

[0035] In summary, compared with the prior art, the embodiments of the present invention have the following advantages: Advantage 1: Precise tape alignment mechanism. When the module two 22 falls under the action of the pushing component 211, the pressing surface one 2231 of the pressing rod 223 squeezes the docking surface one 12231 of the movable block 1223. The movable block 1223 moves in the movable cavity 12211, and pushes the movable plate two 1224 through the spring two 12251, so that the top plate 1227 contacts the tape and pushes it to align. Compared with traditional manual or simple mechanical alignment, this method greatly improves the tape alignment accuracy, ensures the fixed position of the tape during stamping, prevents lateral movement or deviation, effectively guarantees the product size accuracy and consistency, and reduces the scrap rate.

[0036] Advantage 2: Stable tape pressing effect. After the top plate 1227 contacts the tape and cannot push it, it drives the extrusion groove 12271 to squeeze the docking bolt 12282, prompting the pressing plate 1228 to fall and press the two sides of the top of the tape. The clamping plate 1226, the top plate 1227 and the pressing plate 1228 work together to increase the stability of the tape during stamping, avoid shaking or warping, reduce problems such as stamping deformation and material shortage caused by tape instability, make the grid structure more uniform and complete, and at the same time make the multi-layer tapes fit tightly. Under subsequent heating and pressing, the bonding strength of the multi-layer composite metal is improved, the overall performance and service life of the grid are enhanced, and it can also adapt to the fixing requirements of tapes with different sizes and thicknesses.

[0037] Advantage 3: Optimized stamping process. The top docking head 12141 of the ejector rod 1214 of the lifting component 121 of the lower die mechanism 1 always supports the tape during stamping. This not only prevents the tape from displacement or deformation, improves the stamping position accuracy, but also enables the tape to better withstand the pressure of the stamping head 222, avoids cracking or incomplete stamping caused by uneven local stress, improves the stamping quality, and ensures the firmness of the grid structure. In addition, the docking head 12141 shares part of the pressure of the stamping head 222 on the tape, reduces the friction between the stamping head 222 and the tape, reduces the wear of the stamping head 222, extends the service life of the die, the uniform supporting force avoids excessive extrusion damage of the tape, improves the tape utilization rate, reduces the production cost.

[0038] Advantage 4: Efficient waste cleaning process. After stamping is completed, the stamping head 222 inserts into the docking hole one 1212, the spring one 224 is compressed to the limit, the extrusion block three 225 squeezes the extrusion block two 1222, which is transmitted to the extrusion block one 1215 to make it rise, driving the movable plate one 1213 and the ejector rod 1214 to extend. The docking head 12141 pushes the waste into the docking hole two 2221 at the bottom of the stamping head 222, and finally ejects it into the discharge cavity 221. Subsequently, the driving component 2211 in the discharge cavity 221 drives the cleaning brush 2212 to clean the waste, realizing efficient waste cleaning, keeping the working area clean, and improving the production efficiency.

[0039] Advantage 5: Uniform heating and equipment protection. When the connector 12141 enters the discharge cavity 221, the movable plate 1 drives the heating component 12142 to fit with the docking plate 1211. Heat is transferred to the strip in multiple directions through the docking plate 1211, the ejector rod 1214, and the stamping head 222, ensuring uniform heating of the strip and consistent physical and chemical changes in all parts during the pressing process, improving the quality stability of the product. The heating component 12142 is arranged in the movable plate 1 to avoid direct contact with components such as the module 12, the module 22, and the docking plate 1211, preventing thermal damage to these components caused by long-term heating, extending the service life of the mold and related components, reducing the equipment maintenance cost, and improving the reliability and stability of the production process.
