Description

Technical Field

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

[0002] The electrode grid is a major component of a lead-acid battery. It forms the current-collecting framework of the electrodes, conducting, collecting, and distributing current evenly. It also supports the active material and 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 within the frame that form a crisscrossing mesh structure. During charging, electricity is transferred from the outside to the tabs of the grid, then sequentially to the frame and ribs. The discharging sequence is exactly the reverse.

[0003] During the fabrication of electrode grids, the frame and ribs need to be formed. To ensure dimensional accuracy, a certain length is reserved. After the frame and ribs are formed and assembled, they are cut. Currently, the following problems often exist when cutting electrode grids: First, the electrode grids may shift during cutting, affecting the cutting accuracy. Second, to improve the sharpness of the cutter, the entire cutter is sharpened, but the electrode grids to be cut are often in fixed positions, leaving most of the cutter blades idle, resulting in waste. Furthermore, during use and maintenance, technicians are prone to accidentally touching the blades, posing a significant safety hazard. Therefore, it is objectively necessary to develop a cutting device for composite electrode grid processing that offers high cutting accuracy, high blade utilization, and safety and reliability. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for processing composite electrode grids with high cutting accuracy, high blade utilization, and high safety and reliability.

[0005] The purpose of this utility model is achieved as follows: it includes a frame and an operating table mounted on the frame. Multiple vertical rods are mounted on the operating table, with a top plate at the upper end of each rod. Sliding sleeves are fitted onto the vertical rods, and lifting plates are positioned between the sliding sleeves. A cylinder is mounted on the top plate, with the piston rod end of the cylinder passing through the top plate and connecting to the lifting plate. Multiple through holes are machined on the lifting plate, with studs inserted into each hole. Nuts are screwed into the upper ends of the studs, and pressure plates are mounted on the lower ends. A spring is mounted on the stud between the pressure plate and the lifting plate. A cutter mounting plate is mounted on the lifting plate on one side of the pressure plate, with a cutter mounted on the lower end of the cutter mounting plate. Several grooves are machined on the lower surface of the cutter, with blades machined at the top of the grooves. A bottom plate is mounted on the operating table below the pressure plate, and a bottom blade mounting plate is mounted on the operating table below the cutter, with a bottom blade mounted on the upper end of the bottom blade mounting plate.

[0006] Furthermore, a through hole is machined on the operating platform on one side of the bottom knife mounting plate, and a slag guide pipe is installed in the through hole. A slag trough is installed on the frame, and the lower end of the slag guide pipe extends into the slag trough.

[0007] Furthermore, limit strips are provided on both sides of the upper surface of the base plate, and pressure blocks are provided on the lower surface of the lifting plate, with the pressure blocks located above the two limit strips.

[0008] Furthermore, a sliding groove is provided on the base plate, and the limiting strip is slidably connected to the sliding groove via a slider.

[0009] Furthermore, the cutter and the cutter mounting plate, as well as the bottom cutter and the bottom cutter mounting plate, are all connected by bolts.

[0010] Furthermore, a pressure sensor is installed between the end of the piston rod of the cylinder and the lifting plate.

[0011] When this utility model is in operation, the assembled electrode grid with frame and ribs is placed on the base plate, so that a section of material reserved on the upper frame and ribs of the electrode grid extends beyond the edge of the base plate. The corresponding parts of the cutter and bottom blade are aligned according to the required cutting position. After the position is determined, the cylinder is activated, which drives the lifting plate to move down, and simultaneously drives the pressure plate and cutter to move down. When the lower surface of the pressure plate presses against the electrode grid, the electrode grid is fixed between the pressure plate and the base plate. Due to the restriction of the base plate, the pressure plate position is fixed and no longer moves down. The lifting plate continues to move down, the spring is compressed and contracts, and the lifting plate drives the cutter to continue to move down. When the cutter reaches the bottom blade position, the reserved section of frame and ribs is broken by the shearing force between the cutter and the bottom blade, completing the cutting of the electrode grid. The cylinder reverses its operation, driving the lifting plate to move up and reset, so that the pressure plate moves up and away from the electrode grid. The electrode grid can then be removed for the next cutting operation. In operation, before the motor grid is cut and before the cutter contacts the electrode grid, a pressure plate presses down on the electrode grid, firmly fixing it between the pressure plate and the base plate. This effectively prevents displacement of the electrode grid during cutting, ensuring the cutting accuracy of the electrode grid. Secondly, the cutter is not entirely sharpened; instead, grooves are machined at the locations where the electrode grid needs to be cut, with the sharpening treatment done at the root of the grooves. This design not only restricts the position of the electrode grid using the grooves, achieving accurate positioning and enhancing cutting precision, but also avoids idle blades, increasing blade utilization and reducing sharpening costs. Furthermore, during use, maintenance, and repair, the concealed blade location at the root of the grooves reduces the risk of technicians accidentally touching the blade, thus minimizing safety hazards and enhancing safety during operation and maintenance. In summary, this invention offers advantages such as high cutting accuracy, high blade utilization, and safety and reliability. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] like Figs. 1-3 As shown, this utility model includes a frame 1 and an operating table 2 mounted on the frame 1. The operating table 2 has multiple vertical rods 3, with a top plate 4 at the upper end of each rod 3. Sliding sleeves are fitted onto the vertical rods 3, allowing them to slide freely up and down. Lifting plates 5 are positioned between the sliding sleeves. A cylinder 6 is mounted on the top plate 4, with the piston rod end of the cylinder 6 passing through the top plate 4 and connecting to the lifting plate 5. The lifting plate 5 has multiple through holes, into which studs 7 are inserted. Nuts are screwed into the upper end of each stud 7, and the lower end... A pressure plate 8 is provided, and a spring 9 is provided on the stud 7 between the pressure plate 8 and the lifting plate 5. A cutter mounting plate 10 is provided on the lifting plate 5 on one side of the pressure plate 8. A cutter 11 is installed at the lower end of the cutter mounting plate 10. Several grooves 12 are machined on the lower end surface of the cutter 11, and a blade 13 is machined on the top of the grooves 12. A base plate 14 is provided on the operating table 2 below the pressure plate 8. A bottom blade mounting plate 15 is provided on the operating table 2 below the cutter 11. A bottom blade 16 is installed at the upper end of the bottom blade mounting plate 15.

[0018] In operation, the electrode grid 23, after assembling the frame and ribs, is placed on the base plate 14, such that a section of material reserved for the upper frame and ribs of the electrode grid 23 extends beyond the edge of the base plate 14. The cutter 11 and the bottom blade 16 are aligned with the desired cutting position. After determining the position, the cylinder 6 is activated. The cylinder 6 moves the lifting plate 5 downwards, simultaneously moving the pressure plate 8 and the cutter 11 downwards. When the lower surface of the pressure plate 8 presses against the electrode grid 23, the electrode grid 23 is fixed between the pressure plate 8 and the base plate 14, and is supported by the base plate 14. Due to the limitation, the pressure plate 8 is fixed in position and no longer moves down. The lifting plate 5 continues to move down, and the spring 9 is compressed and contracts. The lifting plate 5 drives the cutter 11 to continue to move down. When the cutter 11 reaches the bottom cutter 16, the reserved section of frame and rib material is broken by the shearing force between the cutter 11 and the bottom cutter 16, completing the cutting of the electrode grid 23. The cylinder 6 operates in the opposite direction, driving the lifting plate 5 to move up and reset. The spring 9 gradually extends and resets, causing the pressure plate 8 to move up and away from the electrode grid 23. The electrode grid 23 can then be removed for the next cutting operation.

[0019] In operation, before the motor grid 23 is cut and before the cutter 11 contacts the electrode grid 23, the pressure plate 8 presses down on the electrode grid 23, thus firmly fixing the electrode grid 23 between the pressure plate 8 and the base plate 14. This effectively prevents the electrode grid 23 from shifting or lifting during the cutting process, ensuring the cutting accuracy of the electrode grid 23. Secondly, in this invention, the cutter 11 is not entirely sharpened; instead, a groove 12 is machined at the location where the electrode grid 23 needs to be cut, and a groove 12 is formed at the root of the groove 12. The sharpening process not only restricts the position of the electrode grid 23 by using the groove 12 to achieve the positioning of the electrode grid 23 and enhance the accuracy of the cutting operation, but also avoids the problem of the blade 13 being idle, improves the utilization rate of the blade 13, and reduces the sharpening cost of the blade 13. At the same time, during use, maintenance and upkeep, since the blade 13 of the cutter 11 is concealed at the root of the groove 12, the risk of technicians accidentally touching the blade 13 is reduced, thereby reducing the safety hazards of equipment use and enhancing the safety of use and maintenance processes.

[0020] A through hole is machined on the operating table 2 on one side of the bottom knife mounting plate 15, and a slag guide pipe 17 is installed in the through hole. A slag trough 18 is installed on the frame 1, and the lower end of the slag guide pipe 17 extends into the slag trough 18. When this utility model is running, the shearing force between the cutter 11 and the bottom knife 16 cuts off the reserved excess material. This cut material often piles up messily on the operating table 2, which not only affects the appearance of the equipment but also causes pollution. At the same time, it requires workers to clean it regularly, increasing labor and posing certain safety hazards. To avoid the above problems, the slag guide pipe 17 and the slag trough 18 are set. When the excess material on the electrode grid 23 is cut off, it will first fall into the slag guide pipe 17 and then into the slag trough 18. Only periodic cleaning or replacement of the slag trough 18 is required. In this way, the excess material is automatically collected and cleaned without the need for workers, ensuring the cleanliness of the equipment, improving work efficiency, and reducing the labor intensity of workers.

[0021] Limiting strips 19 are provided on both sides of the upper surface of the base plate 14, and a pressing block 20 is provided on the lower surface of the lifting plate 5. The pressing block 20 is located above the two limiting strips 19. In use, the electrode grid 23 is placed between the two limiting strips 19, and the two limiting strips 19 are used to position the electrode grid 23 so that the electrode grid 23 is in the predetermined position, which facilitates subsequent precise cutting.

[0022] A sliding groove 21 is provided on the base plate 14. The limiting strip 19 is slidably connected to the sliding groove 21 through a slider. The setting of the sliding groove 21 allows the limiting strip 19 to move along it, thereby adjusting the distance between the two limiting strips 19. In the actual production process, the size of the electrode grid 23 may be adjusted according to market demand, process requirements, etc. In order to improve the practicality of this utility model, the limiting strip 19 is set as a movable structure by using the sliding groove 21, thereby adapting to the positioning needs of electrode grids 23 of various specifications and sizes during production.

[0023] To facilitate the installation, maintenance, and upkeep of the cutter 11 and the bottom cutter 16, the cutter 11 is connected to the cutter mounting plate 10, and the bottom cutter 16 is connected to the bottom cutter mounting plate 15, all by bolts.

[0024] A pressure sensor 22 is installed between the piston rod end of cylinder 6 and the lifting plate 5. The pressure sensor 22 is an existing pressure detection instrument. In this utility model, the pressure sensor 22 is installed between the piston rod end of cylinder 6 and the lifting plate 5 to detect the pressure of cylinder 6 on electrode grid 23. The electrode grid 23 in this utility model mainly includes a frame and internal ribs. The frame and ribs are made of an aluminum core with a diameter of 1.6mm covered with an outer layer. If the pressure is too high, it may flatten the frame and ribs, causing deformation or even damage to the frame and ribs, resulting in loss and waste of electrode grid 23 material. In order to prevent this from happening, the pressure sensor 22 is installed to monitor the pressure on the electrode grid 23. When the pressure is too high, it is adjusted in time.

[0025] The electrode grid 23 is cut using this utility model, and the cut is flat and neat, which can better meet the needs of use and has high work efficiency.
