Description

Technical Field

[0001] The present invention relates to the technical field of battery grid processing and manufacturing, and particularly to a continuous casting and lamination forming device for multi-layer composite metal lead-acid battery grids. 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, the grids mostly adopted a single-layer structure of lead-antimony alloy or lead-calcium alloy, and were formed by gravity casting or die casting. However, such single alloy systems have obvious drawbacks. Lead-antimony alloy is prone to accelerating self-discharge of the negative electrode, while lead-calcium alloy will have interface microcracks during deep cycling, shortening the battery life. At the same time, traditional casting processes require high-temperature operations, emit lead smoke and pollute the environment, and have low material utilization rate, resulting in high energy consumption and costs.

[0003] To break through the performance bottleneck of single materials, the industry has turned to the research of multi-layer composite metal grids, and by superimposing different metal layers or adding non-metal reinforcement layers, it is possible to meet the requirements of conductivity, corrosion resistance and light weight. However, there are many technical problems in the current multi-layer grid manufacturing technology.

[0004] In the material tape alignment and pressing link, the alignment accuracy of traditional manual or simple machinery is poor. Relying on the mechanical positioning method of hole column cooperation, when there is thermal expansion or tape deformation, it is easy to cause layer deviation, resulting in increased resistance and uneven corrosion after pressing. Conventional pressing equipment also cannot evenly and accurately distribute pressure. Facing tapes of different thicknesses and materials, it is easy to have problems such as insecure pressing and delamination, seriously affecting the structural stability of the grid.

[0015] Beneficial effects of the continuous casting and laminating forming device for the multi-layer composite metal lead-acid battery grid of the present invention:

[0016] 1. When the upper die mechanism descends, the pressure rod squeezes the movable block through the pressure surface. The movable block pushes the movable plate through the second spring, driving the top plate to contact the strip and push it into alignment. The top plate cooperates with the pressure plate, and can fix strips with different sizes and thicknesses, effectively preventing the strip from moving laterally or shifting during stamping, ensuring the accuracy of the stamping position, greatly improving the dimensional accuracy and consistency of the product, significantly reducing the rejection rate. After the top plate contacts the strip and cannot push it anymore, it drives the extrusion groove to squeeze the docking bolt, causing the pressure plate to fall and press both sides of the top of the strip, which increases the stability of the strip during stamping, avoids its shaking or warping, reduces problems such as stamping deformation and material shortage caused by instability, promotes better fitting of the multi-layer strip, and under the subsequent heating and pressing action, enhances the bonding strength of the multi-layer composite metal, improving the overall performance and service life of the grid.

[0017] 2. During stamping, the top rod of the lifting assembly always supports the strip with the docking head at its top. On the one hand, it can prevent the strip from displacing or deforming, improving the accuracy of the stamping position and the product precision. On the other hand, it enables the strip to better withstand the pressure of the stamping head, avoiding rupture or incomplete stamping caused by uneven local stress, improving the stamping quality, and ensuring 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 strip, reduces the friction between the stamping head and the strip, reduces the wear of the stamping head, extends the service life of the die, and the uniform supporting force avoids excessive extrusion damage to the strip, improves the utilization rate of the strip, and reduces the production cost.

[0018] 3. After stamping is completed, the stamping head of the upper die mechanism is inserted into the docking hole of the lower die mechanism, and the pressure 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 out the waste materials, realizing efficient waste material cleaning, keeping the working area clean, and facilitating the improvement of production efficiency.

[0019] 4. When the top rod pushes the waste materials into the discharge cavity, the movable plate 1 drives the heating assembly to fit with the docking plate, and the heat is transferred to the strip through the docking plate. At the same time, it is transmitted in multiple directions through the top rod and the stamping head, ensuring uniform heating of the strip, ensuring consistent 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, avoiding its 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 die and the mechanism, extending the service life of the die and related components, reducing the equipment maintenance cost, and enhancing the reliability and stability of the production process.

[0038] Please refer to Figures 1 - 10 , a continuous casting and laminating forming device for a multi-layer composite metal lead-acid battery grid, including a lower die mechanism 1. The lower die mechanism 1 includes a main frame 11. An installation cavity 111 is provided at the top of the main frame 11. A module one 12 is arranged in 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. A movable plate one 1213 is slidably connected inside the docking plate 1211. A plurality of ejector rods 1214 are fixed to the top of the movable 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 and is used for accurately positioning the strip.

[0039] An upper die mechanism 2, which includes a positioning slide rod 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 rod 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.

[0040] By adopting the above technical scheme, the pressing surface 1 2231 of the pressing rod 223 and the docking surface 12231 of the movable block 1223 cooperate to align the material strip, the spring 1 224 buffers and transmits the pressure, the extrusion block 3 225 squeezes the extrusion block 2 1222 to eject the waste after stamping, the ejector rod 1214 of the lifting component 121 has a heating component 12142, and after stamping, the movable plate 1213 drives it to fit with the docking plate 1211 to evenly heat the material strip while avoiding high temperature damage to other components. The driving component 2211 and the cleaning brush 2212 in the discharge chamber 221 can clean the waste after stamping.

[0041] A heating component 12142 is provided at a position of the movable plate 1213 near the top rod 1214, and the positioning component 122 includes a fixed shell 1221 fixedly installed in the installation cavity 111, and a movable cavity 12211 is provided inside the fixed shell 1221, and docking grooves 12212 connected to the movable cavity 12211 are symmetrically provided at the top and bottom of the fixed shell 1221, and a movable block 1223 and a movable plate 2 1224 are slidably connected inside the movable cavity 12211, and the top of the movable plate 2 1224 extends to the outside of the fixed shell 1221 and is fixedly connected with a clamping plate 1226, and a top plate 1227 and a pressing plate 1228 are slidably connected inside the clamping plate 1226, and the top plate 1227 and the pressing plate 1228 are respectively used for the preliminary alignment and compression and fixation of the material strip.

[0042] 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.

[0043] 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.

[0044] By adopting the above technical solution, for the joint 12141 with a size smaller than the first docking hole 1212, it does not hinder the insertion of the stamping head 222 during stamping, ensuring smooth stamping operation. The sizes of the stamping head 222 and the first docking hole 1212, and the ejector rod 1214 and the second docking hole 2221 are adapted to each other, ensuring precise cooperation of each component, improving the dimensional accuracy of the product. The second extrusion block 1222 at the bottom of the fixed shell 1221 is slidably connected to the first extrusion block 1215. After stamping, it cooperates with the lifting assembly 121 to smoothly extend the ejector rod 1214 to eject the waste material, improving work efficiency.

[0045] A first 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 second module 22 corresponding to the docking groove 12212. The bottom of the pressure rod 223 extends into 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 first pressure surface 2231 is formed on the outer wall of the pressure rod 223 near the first docking surface 12231. The first pressure surface 2231 is slidably connected to the first docking surface 12231. The bottom of the pressure rod 223 is connected to a third extrusion block 225 through a first spring 224. The third extrusion block 225 is slidably connected to the inner wall of the installation cavity 111. A second pressure surface 2251 is formed on the outer wall of the third extrusion block 225 near the second extrusion block 1222.

[0046] By adopting the above technical solution, when the second module 22 descends, the pressure rod 223 extends into the installation cavity 111 through the docking groove 12212. Its first pressure surface 2231 pushes the first docking surface 12231, prompting the movable block 1223 to move in the movable cavity 12211, and then driving the second movable plate 1224 to bring the top plate 1227 into contact with the strip, achieving precise alignment and 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 pressure surface 2251 of the third extrusion block 225 extrudes the second extrusion block 1222, cooperating with the first extrusion block 1215 to smoothly extend the ejector rod 1214 to eject the waste material, improving the waste material cleaning efficiency and ensuring the continuous and stable operation of the device.

[0047] An extrusion groove 12271 is formed inside the top plate 1227. The lower surface of the pressure plate 1228 is fixedly connected with a mounting plate 12281, and two groups of such mounting plates 12281 are provided and symmetrically distributed on the lower surface of the pressure plate 1228. Each group of mounting plates 12281 has two and is distributed at both ends of the extrusion groove 12271. The inner side of one group of mounting plates 12281 is fixedly connected with a docking bolt 12282 that slides with the inner wall of the extrusion groove 12271, used to drive the pressure plate 1228 to descend when the top plate 1227 moves. An activity rod 1225 is provided on the 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 with one end connected to the movable block 1223 is sleeved outside the activity rod 1225.

[0048] By adopting the above technical solution, when the top plate 1227 is pushed by the second movable plate 1224 to contact the strip and continues to move, the extrusion groove 12271 extrudes the docking bolt 12282, causing the pressing plate 1228 to quickly fall and press the strip tightly. It can adapt to strips of different sizes and thicknesses, solve the problem that traditional pressing equipment is difficult to apply pressure evenly and accurately, ensure that each layer of the strip is closely attached, and at the initial stage when the pressing 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 top plate 1227 to accurately align with the strip, and thus ensuring the accuracy of the stamping position.

[0049] The working principle and usage process of the embodiment of the present invention:

[0050] When the pressing 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 with one end connected to the clamping plate 1226 is provided at the bottom of the pressing plate 1228. A fixing plate 21 is provided at the top of the positioning slide rod 212, and a pushing component 211 with an output end fixedly connected to the second module 22 is provided at the top of the fixing plate 21.

[0051] During use, the strips are stacked together by the conveying mechanism and then sent 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 component 121. When it is necessary to process the strip, the pushing component 211 pushes the upper die mechanism 2 to start falling. When falling, the first pressing surface 2231 will first squeeze the first docking surface 12231. After being squeezed, the first docking surface 12231 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 continuous pushing, the strip can be aligned, ensuring that the strip remains in a fixed position during the stamping process, preventing it from moving horizontally or shifting, making the stamping position accurate, ensuring the dimensional accuracy and consistency of the product, and reducing the scrap rate.

[0052] 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 pressure plate 1228 to fall by squeezing the docking bolt 12282. The falling pressure plate 1228 will 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. This helps to improve the stamping quality, avoid stamping deformation, material shortage and other problems caused by unstable material strips, make the grid structure more uniform and complete, and make the multi-layer material strips fit together better during the stamping process. Under the subsequent heating and pressurization, the bonding between the material strips is tighter, thereby improving the bonding strength of the multi-layer composite metal, improving the overall performance and service life of the grid, and can fix material strips of different sizes and thicknesses. After the top plate 1227 and the pressure plate 1228 align and press the material strip, since the force applied exceeds its bearing capacity, spring two 12251 is compressed, and the movable block 1223 continues to move by compressing spring two 12251. When the pressure rod 223 falls, due to the existence of spring one 224, it cannot directly act on the extrusion block three 225, so that the pressure rod 223 cannot push the extrusion block two 1222 through the extrusion block three 225.

[0053] As the upper mold mechanism 2 falls, the punch head 222 will be driven to punch the material strip. During stamping, the top of the joint 12141 is always against the material strip, providing support under the material strip, which can effectively prevent the material strip from being displaced or deformed during the stamping process, making the stamping position more accurate, thereby improving the dimensional accuracy and consistency of the product. The supporting effect of the joint 12141 can enable the material strip to better withstand the pressure of the punch head 222 during stamping, and avoid the material strip from breaking or incomplete stamping due to local uneven force, which helps to improve the stamping quality and make the stamped grid structure more complete and firm. On the one hand, the joint 12141 can share part of the pressure of the punch head 222 on the material strip, reduce the friction between the punch head 222 and the material strip, thereby reducing the wear of the punch head 222 and extending the service life of the mold. On the other hand, the uniform supporting force can prevent the material strip from being damaged due to excessive extrusion, improve the utilization rate of the material strip, and reduce production costs.

[0054] 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 the third extrusion block 225 will extrude the second extrusion block 1222. The second extrusion block 1222 will transfer the received extrusion to the first extrusion block 1215, so that the first extrusion block 1215 is extruded and rises. The rising 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 hold the waste material after stamping and make it move inside the docking hole two 2221. The stamping head 222 continues to fall until the docking head 12141 pushes the waste material out into the discharge cavity 221. Then, the drive assembly 2211 inside the discharge cavity 221 works, and the drive cleaning brush 2212 clears the waste material out of the discharge cavity 221.

[0055] When the docking head 12141 enters the inner part of the discharge cavity 221, the fixed plate 21 will completely press on the strip, and 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 the strip to be heated more evenly on the entire contact surface, avoiding local overheating or overcooling, thus ensuring the consistency of physical and chemical changes in each part of the strip during the pressing process and improving the stability of product quality. The heating component 12142 is arranged in the first movable plate 1213, avoiding the direct contact of the heating component 12142 with the upper die mechanism 2 or other components vulnerable to high temperature, reducing the thermal damage of high temperature to the die and mechanism, which helps to extend the service life of the die and related components, reduce the equipment maintenance cost, and also improve the reliability and stability of the production process.

[0056] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0057] Advantage one: Precise strip 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 extrudes the docking surface one 12231 of the movable block 1223. The movable block 1223 moves in the movable cavity 12211 and pushes the second movable plate 1224 through the second spring 12251, so that the top plate 1227 contacts the strip and pushes it to align. Compared with the traditional manual or simple mechanical alignment, this method greatly improves the strip alignment accuracy, ensures the fixed position of the strip during stamping, prevents lateral movement or deviation, effectively guarantees the product size accuracy and consistency, and reduces the scrap rate.

[0058] Advantage 2: Stable tape pressing effect. After the top plate 1227 comes into contact with the tape and cannot be pushed, it drives the extrusion groove 12271 to squeeze the docking bolt 12282, prompting the pressing plate 1228 to fall and press both 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 stamping deformation, material shortage and other problems caused by unstable tape, make the grid structure more uniform and complete. At the same time, the multi-layer tapes are closely fitted, which improves the bonding strength of the multi-layer composite metal under subsequent heating and pressing, enhances the overall performance and service life of the grid, and can also meet the fixing requirements of tapes with different sizes and thicknesses.

[0059] Advantage 3: Optimized stamping process. The top 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 accuracy of the stamping position, but also enables the tape to better withstand the pressure of the stamping head 222, avoids rupture 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 to the tape, improves the utilization rate of the tape, reduces the production cost.

[0060] Advantage 4: Efficient waste cleaning process. After stamping is completed, the stamping head 222 inserts into the docking hole 1212, the first spring 224 is compressed to the limit, the third extrusion block 225 squeezes the second extrusion block 1222, which is transmitted to the first extrusion block 1215 to make it rise, driving the first movable plate 1213 and the ejector rod 1214 to extend. The docking head 12141 pushes the waste into the docking hole 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.

[0061] Advantage 5: Uniform heating and equipment protection. When the docking head 12141 enters the discharge cavity 221, the first movable plate 1213 drives the heating component 12142 to fit with the docking plate 1211. The heat is transmitted to the tape in multiple directions through the docking plate 1211, the ejector rod 1214 and the stamping head 222, ensuring uniform heating of the tape, ensuring the consistency of physical and chemical changes in each part during the pressing process, and improving the quality stability of the product. The heating component 12142 is arranged in the first movable plate 1213 to avoid direct contact with components such as the first module 12, the second module 22 and the docking plate 1211, avoid thermal damage to these components caused by long-term heating, extend the service life of the die and related components, reduce the equipment maintenance cost, and improve the reliability and stability of the production process.
