Description

Technical Field

[0001] This utility model relates to the field of plate grid bending technology, specifically to a rhomboid bending device for processing composite electrode plate grids. Background Technology

[0002] The electrode grid is a major component of a lead-acid battery, serving as the current-collecting skeleton of the electrodes. It conducts and collects current, ensuring uniform current distribution, and supports the active material. It acts as a carrier for the lead paste, the active material; the lead paste is applied to the grid and cured to form the electrode plates. The charging and discharging of a lead-acid battery is primarily accomplished by the grid. A mesh-type electrode grid includes tabs, a frame, and ribs forming a crisscrossing mesh structure within the frame. During charging, electricity is transferred from the outside to the tabs of the grid, then sequentially to the frame and ribs. The discharge sequence is exactly the reverse. During the manufacturing process of the electrode grid, the ribs need to be bent and shaped. Existing bending devices suffer from poor forming results, low efficiency, long processing times, and low automation, failing to meet the needs of enterprises for frame bending. Therefore, the development of a highly automated, efficient, and effective diamond-shaped bending device for composite electrode grid processing is objectively necessary. Utility Model Content

[0003] The purpose of this invention is to provide a diamond bending device for processing composite electrode grids with a high degree of automation, high working efficiency, and good forming effect.

[0004] The purpose of this utility model is achieved as follows: It includes a worktable and symmetrically arranged feeding mechanisms on both sides of the worktable. The feeding mechanism includes fixed and movable bars arranged parallel to each other at intervals. A feeding drive mechanism is installed on the worktable to drive the movable bars to move up and down. A push bar is provided on one side of the feeding mechanism. A push drive mechanism is installed on the worktable to drive the push bar to move back and forth horizontally and up and down. On the other side of the feeding mechanism, a pair of bending blocks, several pairs of anti-deformation blocks, and several pairs of outer modules with arc-shaped ends are arranged symmetrically in sequence. The anti-deformation blocks and outer modules are arranged alternately. Several forming translation cylinders are provided on the worktable to drive the translation of each outer module. An inner mold through hole is machined at the center of the worktable between each pair of anti-deformation blocks. A cylindrical inner mold is movably installed in the through hole. An end through hole is machined at the end of the center of the worktable. An end stop is movably installed in the end through hole. The inner side of the end stop has an arc-shaped structure. A lifting drive mechanism is installed on the worktable to drive the inner mold and the end stop to move up and down. A conveyor belt is provided on the side of the worktable near the end stop.

[0005] Furthermore, a guide plate is inclinedly installed at the inner end of both the fixed strip and the movable strip, and the two guide plates form a figure-eight structure.

[0006] Furthermore, the feeding mechanism includes a feeding cylinder and a connecting rod. The feeding cylinder is installed on the lower surface of the worktable and is located on the side close to the fixed bar. The piston rod of the feeding cylinder passes through the worktable and is connected to the movable bar through the connecting rod.

[0007] Furthermore, the pushing drive mechanism includes a bracket and a horizontal plate mounted on the bracket. A groove is machined along the horizontal direction on the horizontal plate, and a slider is slidably installed in the groove. Mounting plates are provided on both sides of the horizontal plate, and a screw is installed between the two mounting plates. A drive motor is driven to one side of the screw, and a drive block is screwed onto the screw. An L-shaped plate is provided at the end of the slider and the drive block. A pushing lifting cylinder is installed on the top of the L-shaped plate, and the piston rod end of the pushing lifting cylinder is connected to the pushing bar.

[0008] Furthermore, rollers are provided at the ends of both the bending stop and the anti-deformation stop.

[0009] Furthermore, the worktable is machined with slide rails, and the bottom of the outer module is slidably connected to the slide rails.

[0010] Furthermore, the lifting drive mechanism that drives the inner mold to move up and down includes a frame and an inner mold lifting cylinder mounted on the frame. The frame is fixed to the lower surface of the worktable, and the piston rod end of the inner mold lifting cylinder is connected to a strip lifting plate, which is connected to the bottom of each inner mold.

[0011] Furthermore, a sensor is provided at the end of one of the feeding mechanisms.

[0012] Furthermore, the upper end of the inner mold has a tapered structure with the pointed end facing upwards.

[0013] This invention includes a feeding mechanism. A feeding channel is formed between the fixed and movable bars of the feeding mechanism. During operation, the straightened composite electrode material is inserted into the feeding channel of one of the feeding mechanisms and continues to extend along the channel until the end of the composite electrode material reaches the end of the feeding channel of the other feeding mechanism. At this point, the length of the composite electrode material meets the usage requirements. The composite electrode material is then cut using a cutting structure found in existing technology. The feeding drive mechanism is then activated, causing the movable bar to move upward, leaving a gap for the composite electrode material to pass through. Then... The pusher drive mechanism moves the pusher bar to one end of the worktable and lowers it in preparation for bending. The pusher drive mechanism is then restarted, moving the pusher bar towards the feeding mechanism. The end of the pusher bar contacts the middle of the composite electrode material and continues to push the composite electrode material forward. The composite electrode material begins to be folded in half from the middle. When it passes the bending stop, the bending angle reaches the required folding angle. Then, several pairs of anti-deformation stops shape the bent composite electrode material to prevent deformation until it reaches the end stop. The bending section undergoes initial shaping. The pusher bar stops its lateral movement and instead moves upward and backward, causing it to leave the composite electrode material and return to its original position. The lifting drive mechanism then moves the inner mold upward. At this point, the composite electrode material is bent from the middle into a long, U-shaped structure. After the inner mold moves upward, it is positioned inside the long, U-shaped structure. The pairs of forming translation cylinders are activated sequentially, moving along the end blocks towards the feeding mechanism. Each pair of forming translation cylinders pushes the outer module towards each other, pushing the composite electrode material from both sides. Together with the inner mold, this causes the composite electrode material to undergo a complex bending process. Once the required deformation is achieved, the diamond-shaped bending of the composite electrode plate grid ribs is completed. The lifting drive mechanism drives the inner mold and end stop blocks to move down and reset. The pushing drive mechanism is then restarted, driving the pushing bar to move towards the bent ribs and push them onto the conveyor belt outside the worktable. Then the pushing bar moves back and resets, thus completing a complete diamond-shaped bending of the composite electrode plate grid ribs. During operation, new composite electrode material is continuously fed in, and the above steps are repeated to continuously complete the diamond-shaped bending of the composite electrode plate grid ribs. In this invention, through the cooperation of various mechanisms, the diamond bending and removal of the composite electrode plate grid ribs after the material enters the device are all carried out in a fully automated assembly line operation. The degree of mechanization is high and the processing accuracy is high. This not only saves labor costs but also improves work efficiency. At the same time, by avoiding manual intervention, the potential for errors caused by manual intervention is reduced, improving the efficiency and quality of the diamond bending of the ribs. The bending and forming effect is better, and the standardization of the diamond bending of the ribs is improved. This results in good consistency and yield of the composite electrode plate grid ribs, reducing the defect rate and scrap rate after rib bending. This can meet the enterprise's needs for diamond bending processing of composite electrode plate grid ribs.In summary, this utility model has the advantages of high automation, high work efficiency, and good molding effect.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the present invention shall fall within the protection scope of the present invention.

[0022] like Figures 1-6As shown, this utility model includes a workbench 1 and feeding mechanisms symmetrically arranged on both sides of the workbench 1. The feeding mechanism includes fixed bars 2 and movable bars 3 arranged parallel to each other at intervals. A feeding drive mechanism is installed on the workbench 1 to drive the movable bars 3 to move up and down. A push bar 4 is provided on one side of the feeding mechanism. A push drive mechanism is installed on the workbench 1 to drive the push bar 4 to move back and forth horizontally and up and down. On the other side of the feeding mechanism, a pair of bending blocks 5, several pairs of anti-deformation blocks 6, and several pairs of outer modules 7 with arc-shaped ends are arranged symmetrically in sequence. The anti-deformation blocks 6 and the outer modules 7 are connected to each other. The worktable 1 is arranged in an interlaced manner and is equipped with several forming translation cylinders 8 that drive the translation of each outer module 7. Each pair of anti-deformation blocks 6 has an inner mold through hole machined at the center of the worktable 1. A cylindrical inner mold 9 is movably installed in the inner mold through hole. An end through hole is machined at the end of the center of the worktable 1. An end block 10 is movably installed in the end through hole. The inner side of the end block 10 has an arc-shaped structure. A lifting drive mechanism is installed on the worktable 1 to drive the inner mold 9 and the end block 10 to move up and down. A conveyor belt 11 is provided on one side of the worktable 1 near the end block 10.

[0023] This invention includes a feeding mechanism. A feeding channel is formed between the fixed bar 2 and the movable bar 3 of the feeding mechanism. During operation, the straightened composite electrode material is inserted into the feeding channel of one of the feeding mechanisms and continues to extend along the channel until the end of the composite electrode material reaches the end of the feeding channel of the other feeding mechanism. At this point, the length of the composite electrode material meets the usage requirements. The composite electrode material is then cut using a cutting structure found in existing technology. The feeding drive mechanism is activated, causing the movable bar 3 to move upward, leaving a gap for the composite electrode material to pass through. Then, a pushing drive mechanism... Move the pusher bar 4 to one end of the worktable 1 and lower it to prepare for bending. Restart the pusher drive mechanism to move the pusher bar 4 towards the feeding mechanism. The end of the pusher bar 4 contacts the middle of the composite electrode material and continues to push the composite electrode material forward. The composite electrode material begins to be folded in half from the middle. When it passes the bending stop 5, the bending angle reaches the folding requirement. Then, several pairs of anti-deformation stops 6 shape the bent composite electrode material to prevent deformation until it reaches the end stop 10. This completes the initial bending of the composite electrode material. During molding, the pusher bar 4 stops moving laterally and instead moves upward and backward, causing it to leave the composite electrode material and return to its original position. The lifting drive mechanism then moves the inner mold 9 upward. At this point, the composite electrode material is bent from the middle into a long, U-shaped structure. After the inner mold 9 moves upward, it is positioned inside the long, U-shaped structure. The pairs of molding translation cylinders 8 are then activated sequentially, moving along the end stop 10 towards the feeding mechanism. Each pair of molding translation cylinders 8 pushes the outer module 7 towards each other, pushing the composite electrode material from both sides. Together with the inner mold 9, this causes the composite electrode material to undergo the required deformation. This completes the diamond-shaped bending of the composite electrode plate grid ribs 28. The lifting drive mechanism drives the inner mold 9 and the end stop 10 to move down and reset. The pushing drive mechanism is then restarted, driving the pushing bar 4 to move towards the bent ribs 28 and push the ribs 28 to be moved onto the conveyor belt 11 outside the worktable 1. Then the pushing bar 4 moves back and resets, thus completing a complete diamond-shaped bending of the composite electrode plate grid ribs. During operation, new composite electrode material is continuously fed in, and the above steps are repeated to continuously complete the diamond-shaped bending of the composite electrode plate grid ribs 28.

[0024] In this invention, through the cooperation of various mechanisms, the diamond bending and removal of the composite electrode plate grid ribs 28 after the material enters the device are all carried out in a fully automated assembly line operation. The degree of mechanization is high and the processing accuracy is high. This not only saves labor costs but also improves work efficiency. At the same time, by avoiding manual intervention, the possibility of errors caused by manual intervention is reduced, which improves the efficiency and quality of diamond bending of the ribs 28. The bending and forming effect is better, which improves the standardization of diamond bending of the ribs 28. This makes the manufactured composite electrode plate grid ribs 28 have good consistency and yield, and reduces the defect rate and scrap rate after bending of the ribs 28. It can meet the enterprise's needs for diamond bending processing of composite electrode plate grid ribs 28.

[0025] A guide plate 12 is inclinedly installed at the inner end of both the fixed strip 2 and the movable strip 3, forming a figure-eight structure. When the composite electrode material is fed, it extends from the feeding channel of one feeding mechanism and then into the feeding channel of the other feeding mechanism. During this process, due to insufficient straightness of the composite electrode material or other problems, the end of the composite electrode material may abut against the end of the fixed strip 2 or the movable strip 3, preventing the feeding process from being completed smoothly. To solve this problem, the guide plate 12 is set up to guide the composite electrode material, enabling it to complete the feeding process smoothly and improving work efficiency.

[0026] The feeding mechanism includes a feeding cylinder 13 and a connecting rod 14. The feeding cylinder 13 is installed on the lower surface of the worktable 1 and is located on the side closer to the fixed strip 2. The piston rod of the feeding cylinder 13 passes through the worktable 1 and is connected to the movable strip 3 through the connecting rod 14. In practice, the feeding cylinder 13 drives the connecting rod 14 to move up and down. When the composite electrode material is in place, the feeding cylinder 13 drives the movable strip 3 to move up through the connecting rod 14. A gap is left between the lower movable strip 3 and the worktable 1 to facilitate the sweeping of the composite electrode material when it is bent. Conversely, when the composite electrode material leaves the feeding mechanism, the feeding cylinder 13 can drive the movable strip 3 to move down, so that a feeding channel is formed between the fixed strip 2 and the movable strip 3, which facilitates the introduction of the composite electrode material.

[0027] The material pushing drive mechanism includes a bracket 15 and a horizontal plate 16 mounted on the bracket 15. A groove is machined on the horizontal plate 16, and a slider 17 is slidably installed in the groove. Mounting plates 18 are provided on both sides of the horizontal plate 16, and a screw 19 is installed between the two mounting plates 18. A drive motor is connected to one side of the screw 19. A drive block 20 is screwed onto the screw 19. An L-shaped plate 21 is provided at the end of the slider 17 and the drive block 20. A material pushing lifting cylinder 22 is installed on the top of the L-shaped plate 21, and the piston rod end of the material pushing lifting cylinder 22 is connected to the material pushing bar 4. The pusher drive mechanism has two functions: first, it drives the pusher bar 4 to move back and forth laterally, with the lateral movement direction parallel to the length direction of the worktable 1; second, it drives the pusher bar 4 to move up and down. In practice, the drive motor drives the screw 19 to rotate, which in turn causes the drive block 20 to slide laterally on the screw 19, thereby sequentially driving the L-shaped plate 21, the pusher lifting cylinder 22, and the pusher bar 4 to move back and forth laterally. The up and down movement of the pusher bar 4 is achieved by the pusher lifting cylinder 22. During the above process, the slider 17 is slidably installed in the slide groove to ensure the stability of the pusher bar 4 during lateral translation.

[0028] Rollers 23 are provided at the ends of both the bending stop 5 and the anti-deformation stop 6. The two bending stops 5 are used to hold the two ends of the composite electrode material, and the pusher bar 4 pushes the middle of the composite electrode material to complete the bending of the composite electrode material. The anti-deformation stop 6 is used to prevent the composite electrode material from deforming and shifting after bending. It can be seen that during use, the composite electrode material is in contact with the bending stop 5 and the anti-deformation stop 6. If the friction between the composite electrode material and the bending stop 5 or between the composite electrode material and the anti-deformation stop 6 is too large, it may affect the bending and anti-deformation effect of the composite electrode material, and thus affect the quality of the grating rib 28 after bending. In order to prevent the above problems, rollers 23 are provided at the ends of the bending stop 5 and the anti-deformation stop 6 to greatly reduce the friction between the composite electrode material and the bending stop 5 and between the composite electrode material and the anti-deformation stop 6. Under the action of bending and anti-deformation, the bending quality of the rib 28 is ensured.

[0029] The workbench 1 is equipped with a slide rail. The bottom of the outer module 7 is slidably connected to the slide rail. When the outer module 7 moves laterally, it will be restricted and guided by the slide rail to prevent problems such as skewing or displacement of the outer module 7 and the forming process of the rib 28.

[0030] The lifting drive mechanism that drives the inner mold 9 to move up and down includes a frame 24 and an inner mold lifting cylinder 25 mounted on the frame 24. The frame 24 is fixed to the lower surface of the worktable 1. The piston rod end of the inner mold lifting cylinder 25 is connected to a strip lifting plate 26, which is connected to the bottom of each inner mold 9. The inner mold lifting cylinder 25 is existing equipment. When the device performs diamond bending of the rib 28, the inner mold lifting cylinder 25 drives the strip lifting plate 26 to move upward, so that all the inner molds 9 extend above the worktable 1 for bending of the rib 28. After the bending of the rib 28 is completed, the inner mold lifting cylinder 25 drives the strip lifting plate 26 and the inner mold 9 to move down below the worktable 1 to prevent the inner mold 9 from interfering with the operation of the subsequent pusher bar 4. In this utility model, the structure for driving the end stop 10 to move up and down is similar to the structure for driving the end stop 10 to move up and down. It only needs to be able to easily move the end stop 10 up to the top of the worktable 1 and down to the bottom of the worktable 1. It can be set according to the actual situation during actual installation.

[0031] A sensor 27 is provided at the end of one of the feeding mechanisms. The sensor 27 is an existing detection instrument. In this utility model, the composite electrode material extends from the end of one feeding mechanism until it reaches the end of the other feeding mechanism. When the end of the composite electrode material abuts against the sensor 27, the sensor 27 transmits a signal to the control system of the device, indicating that the composite electrode material has arrived, and subsequent cutting and bending work can be carried out, thereby improving the automation level and work efficiency of the device.

[0032] The upper end of the inner mold 9 is a cone-shaped structure with the tip pointing upwards. In actual use, it was found that when the inner mold 9 rises from the worktable 1, its edge may come into contact with the composite electrode material, thereby lifting the composite electrode material and causing the device to malfunction. To avoid this situation, the upper end of the inner mold 9 is set as a cone-shaped structure with the tip pointing upwards. When the inner mold 9 rises, it avoids contact between its edge and the composite electrode material, thereby ensuring that the device can operate normally and improving the bending efficiency of the rib 28.

[0033] The composite electrode grid in this invention mainly includes a frame and internal ribs 28, and the frame and ribs 28 are structured as an aluminum core with a diameter of 1.6mm covered by an outer layer.
