Description

Technical Field

[0001] This invention belongs to the field of battery grid processing and manufacturing technology, and particularly relates to a grid forming mold. Background Technology

[0002] In recent years, with the vigorous promotion of new energy sources, lead-acid batteries have been widely used in the electric vehicle manufacturing industry. The grid is a major component of the battery, and its shape design and quality have a significant impact on battery performance. The grid shape directly determines its contact area with the active material, thus affecting energy storage efficiency and capacity. However, different grid shapes require corresponding molds for processing. For grids with complex shapes, the mold design process is complicated, manufacturing is difficult, the grid forming process is cumbersome, and requires significant manual intervention. Therefore, we propose a grid forming mold device to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a plate grid forming mold capable of pressing a single lead-clad aluminum wire into a folded arc shape and a forming method thereof. The device can first bend a single lead-clad aluminum wire into a U-shape through the movement of the mold, then fold the two opposite sides of the U-shape into an arc shape, and the upper end pressing demolding mechanism presses down to press the formed lead-clad aluminum wire into the wire assembly tray. This process does not require manual intervention and can prevent the formed lead-clad aluminum wire from deforming during the pressing demolding process. It can greatly save time and manpower while ensuring the forming accuracy of the lead-clad aluminum wire.

[0004] To achieve the purpose of this invention, the following technical solution is adopted:

[0005] This invention discloses a plate grid forming mold, comprising: a frame, a worktable, a pressing and demolding mechanism, supporting side plates, a wire assembly reel, a long guide rod assembly, a short guide rod, a middle mold assembly, a side mold assembly, an end pressure plate, and a support platform. The pressing and demolding mechanism is mounted on the upper part of the frame. A worktable is fixed on the frame directly below the pressing and demolding mechanism. The wire assembly reel is mounted on the support platform below the worktable. A long guide rod assembly is mounted at one end of the worktable, and a short guide rod is fixed at the other end. An end pressure plate is fixed on the worktable near the long guide rod assembly. Two supporting side plates, splitting from the center of the worktable, are mounted on the worktable between the end pressure plate and the short guide rod. The supporting side plates are installed in grooves in the worktable. At one end of the end pressure plate... Two side mold assemblies are fixed on symmetrical sides, extending along the length of the supporting side plate. A middle mold assembly moves from between two short guide rods to the space enclosed by the two side mold assemblies and the end pressure plate directly below the pressing demolding mechanism. The middle mold assembly includes a middle template and several fixed posts. The upper end of the middle template has several upper through holes, and a side through groove is formed on the side of the middle template corresponding to each upper through hole. Several fixed posts are located at the lower end of the middle template. The upper through holes and fixed posts are staggered along the length of the middle template. A guide protrusion is located on each side of the middle template, and the guide protrusions slide along the sides of the two side mold assemblies. The side mold assembly includes a side pressure rod, an upper pressure plate, and... The system includes a lower pressure plate, a pin, a side pressure roller or side pressure block, and a spring. One end of the upper and lower pressure plates is fixed to one end of the end pressure plate. The upper pressure plate is mounted on the lower pressure plate. Along the length of the lower pressure plate, several lower side grooves are formed on one side of the lower pressure plate near the middle mold assembly. These lower side grooves communicate with the side through grooves. Side pressure rollers or side pressure blocks are installed in the lower side grooves. The side pressure rod is "U"-shaped. The center of the upper end of the side pressure roller or side pressure block is connected to one side of the lower end of the side pressure rod via a pin. The other side of the lower end of the side pressure rod passes through the other side of the lower pressure plate. One end of the spring is mounted on the upper end of the side pressure rod. An upper side groove is formed on the outer side of the upper pressure plate. The other end of the upper end of the side pressure rod with the spring is mounted in the upper side groove. The aforementioned guide protrusions are located inside the two upper pressure plates. The sliding mechanism slides within the side groove; the long guide rod assembly includes: push rods, long guide plates, and push rod connectors. Two long guide plates are fixed on the worktables on both sides of the side mold assembly. The push rod connectors are fixed to one end of the two push rods. The push rod connectors and the two push rods form an open frame. This open frame moves between the two long guide plates, pushing the push rod connectors. The two push rods push the other side of the side pressure rods, causing the side pressure rollers or side pressure blocks to pass through the side through grooves and press against the lead-clad aluminum wire. A material drop groove is opened in the center of the worktable. After the lead-clad aluminum wire is pressed, the supporting side plates move from the center of the worktable to both sides. The downward pressing demolding mechanism descends and inserts into the upper through hole, causing the lead-clad aluminum wire to fall from the fixed column into the wire assembly grid of the wire assembly disc.

[0006] The plate grid forming mold of the present invention, wherein: the wire assembly spool moves along a direction perpendicular to the worktable via a lead screw.

[0007] The plate grid forming mold of the present invention includes: the pressing demolding mechanism comprising: a cylinder, a cylinder connector, a pressing crossbeam and pressing columns. The upper end of the pressing crossbeam is connected to the cylinder through the cylinder connector. Several pressing columns are fixed at the lower end of the pressing crossbeam. The cylinder drives the pressing columns to move downward. The pressing columns enter the upper through hole and press the lead-clad aluminum wire into the wire assembly grid of the wire assembly reel.

[0008] The plate grid forming mold of the present invention includes a guide wheel installed at the end of the middle mold assembly that enters the upper pressure plate.

[0009] The plate grid forming mold of the present invention includes a set of side pressure rollers or side pressure blocks and side pressure rods mounted on the side mold assembly near the guide wheel.

[0010] The plate grid forming mold of the present invention, wherein: the end of the short guide rod near the side mold assembly is wedge-shaped; the other end of the push rod is wedge-shaped.

[0011] The plate grid forming mold of the present invention includes a plurality of wire meshes arranged in the wire mesh tray along a direction perpendicular to the worktable.

[0012] The method for forming lead-clad aluminum wire using the grid forming mold of the present invention, wherein the initial position of the grid forming mold is that the middle mold assembly is located between two short guide rods at the other end of the worktable, the open frame composed of two push rods and push rod connectors is located at one end of the worktable, the wire assembly grid of the wire assembly reel is not filled with lead-clad aluminum wire, the two supporting side plates are located in the center of the worktable, and the downward demolding mechanism is located at the top of the frame, wherein the method includes the following steps:

[0013] (a) Feeding the straight lead-clad aluminum wire into the grid forming mold.

[0014] A straight lead-clad aluminum wire is fed into the ends of two side mold assemblies near the guide wheel in a direction perpendicular to the worktable, and the center of the lead-clad aluminum wire is aligned with the center line of the worktable.

[0015] (ii) Bend the lead-clad aluminum wire into a U-shape.

[0016] The middle mold assembly is pushed out from the short guide rod and inserted between the two side mold assemblies. The lead-clad aluminum wire is looped around the fixing post of the middle mold assembly and bent into a U-shape.

[0017] (iii) The two opposite sides of the lead-clad aluminum wire are extruded into shape.

[0018] The open frame, consisting of two push rods and push rod connectors, is pushed along two long guide plates toward the side mold assembly. The push rods push the other side of several side pressure rods, causing them to move along the lower side groove toward the center line of the worktable. The push rods drive the side pressure rollers or side pressure blocks to pass through the side through groove of the middle mold assembly and enter between the fixed columns of the middle mold assembly, squeezing the two opposite sides of the lead-clad aluminum wire together. After the lead-clad aluminum wire is formed, the open frame consisting of the two push rods and push rod connectors returns to its original position.

[0019] (iv) The formed lead-clad aluminum wire falls from the workbench into the wire assembly reel.

[0020] Two support side plates are pulled outward from both sides of the workbench, exposing the material drop chute on the workbench. The cylinder drives the lower pressure column to move downward, passing through the upper through hole. The lower pressure column presses against the two opposite sides of the lead-clad aluminum wire, squeezing them together. The lead-clad aluminum wire falls off the fixed column and enters a wire assembly grid of the wire assembly reel. Driven by the lead screw, the wire assembly reel moves one wire assembly grid position in a direction perpendicular to the workbench, so that the wire assembly grid facing the next material drop is not filled with lead-clad aluminum wire. The two support side plates and the cylinder return to their original positions.

[0021] The working principle of this invention is:

[0022] After a single lead-clad aluminum wire is fed into the inlet to the specified length and cut, the support side plates on both sides of the workbench panel move toward the center of the workbench panel until they contact each other, and then the support side plates stop moving. The middle mold assembly moves to the left, bending the single lead-clad aluminum wire into a U-shape during the movement. After the middle mold assembly is in place, the push rod assembly moves to the right, squeezing the side pressure rollers or side pressure block assemblies on both sides of the side pressure assembly during the movement. This causes the side pressure rollers or side pressure block assemblies to squeeze the two opposite sides of the U-shaped lead-clad aluminum wire, thus pressing out an arc shape. When the push rod assembly gradually moves to squeeze the side pressure block assemblies, the two side pressure block assemblies squeeze the tail of the arc-shaped lead-clad aluminum wire, aligning and pressing the two sides of the tail. After holding the pressure for a period of time, the push rod assembly moves to the left. During the movement, the side pressure block assemblies and side pressure rollers or side pressure block assemblies in the side pressure assembly are released and popped out to the sides away from the formed lead-clad aluminum wire. The two support side plates move to the sides of the lead-clad aluminum wire respectively, separating from the formed lead-clad aluminum wire. After moving to the position, the downward pressing demolding mechanism presses down to press the formed lead-clad aluminum wire into the corresponding position in the wire assembly tray. Since multiple formed lead-clad aluminum wires need to be placed side by side in each assembly reel, after the pressing and demolding mechanism presses a single formed lead-clad aluminum wire into the corresponding position in the assembly reel, the pressing and demolding mechanism rises, and the assembly reel moves a certain distance so that the position of the next wire to be assembled in the assembly reel is in place. This is the cycle of forming and assembling a single lead-clad aluminum wire, and the cycle is repeated until the assembly of the entire reel of formed lead-clad aluminum wire is completed. After the assembly of the entire reel of wire is completed, it is conveyed to the next workstation, and the next empty assembly reel to be assembled is conveyed into place, and the forming and assembly of the next reel of lead-clad aluminum wire begins.

[0023] The beneficial effects of the plate grid forming mold device of the present invention are:

[0024] The plate grid forming mold device of the present invention is a forming mold device for pressing a single lead-clad aluminum wire into a folded arc shape. The device can first bend the single lead-clad aluminum wire into a U-shape through the movement of the mold, and then fold the two opposite sides of the U-shape into an arc shape. The upper end pressing demolding mechanism presses down to press the formed lead-clad aluminum wire into the wire assembly tray. This process does not require manual intervention and can prevent the formed lead-clad aluminum wire from deforming during the pressing demolding process. It can greatly save time and manpower while ensuring the forming accuracy of the lead-clad aluminum wire. Attached Figure Description

The pressing demolding mechanism 3 is installed at the upper end of the frame 1. The worktable 2 is fixed on the frame 1 directly below the pressing demolding mechanism 3. The wire assembly plate 5 is installed on the support platform 27 below the worktable 2. A long guide rod assembly 6 is installed at one end of the worktable 2, and a short guide rod 7 is fixed at the other end of the worktable 2. An end pressure plate 10 is fixed on the worktable 2 near the long guide rod assembly 6. Two support side plates 4, which split open from the center of the worktable 2, are installed on the worktable 2 between the end pressure plate 10 and the short guide rod 7. The support side plates 4 are installed in the groove of the worktable 2. A side mold assembly 9 is fixed on each of the symmetrical sides of one end of the end pressure plate 10. The two side mold assemblies 9 extend along the length of the support side plates 4. The middle mold assembly 8 moves from between the two short guide rods 7 to the space enclosed by the two side mold assemblies 9 and the end pressure plate 10 directly below the pressing demolding mechanism 3.

[0036] like Figures 5 to 7 and Figure 9 As shown, the middle mold assembly 8 includes: a middle mold plate 28 and several fixing posts 22. The upper end of the middle mold plate 28 has several upper through holes 13. A side through groove 29 is opened on the side of the middle mold plate 28 corresponding to the upper through holes 13. There are several fixing posts 22 at the lower end of the middle mold plate 28. The upper through holes 13 and fixing posts 22 are staggered in the length direction of the middle mold plate 28. There is a guide protrusion 24 on each side of the middle mold plate 28. The guide protrusion 24 slides along the side of the two side mold assemblies 9 respectively.

[0037] like Figures 5 to 7 As shown, the side mold assembly 9 includes: a side pressure rod 11, an upper pressure plate 12, a lower pressure plate 15, a pin 30, a side pressure wheel or side pressure block 16, and a spring 21. One end of the upper pressure plate 12 and the lower pressure plate 15 is fixed to one end of the end pressure plate 10. The upper pressure plate 12 is mounted on the lower pressure plate 15. Along the length of the lower pressure plate 15, several lower side grooves 20 are opened on the side of the lower pressure plate 15 near the middle mold assembly 8. The lower side grooves 20 communicate with the side through grooves 29. The side pressure wheel or side pressure block 16 is installed in the lower side grooves 20. The side pressure rod 11 is "U"-shaped. The center of the upper end of the side pressure wheel or side pressure block 16 is connected by a pin. 30 is connected to one side of the lower end of the side pressure rod 11. The other side of the lower end of the side pressure rod 11 passes through the other side of the lower pressure plate 15. One end of the spring 21 is installed on the upper end of the side pressure rod 11. An upper side groove 19 is opened on the outer side of the upper pressure plate 12. The other end of the upper end of the side pressure rod 11 with the spring 21 is installed in the upper side groove 19. The aforementioned guide protrusions 24 slide in the grooves on the inner side of the two upper pressure plates 12 respectively. At the end of the middle mold assembly 8 entering the upper pressure plate 12, a guide wheel 26 is installed respectively. A set of side pressure wheels or side pressure blocks 16 and side pressure rods 11 are also installed on the side mold assembly 9 near the guide wheel 26.

[0038] like Figures 4 to 7 As shown, the long guide rod assembly 6 includes: push rods 17, long guide plates 18, and push rod connectors 14. Two long guide plates 18 are fixed to the worktables 2 on both sides of the side mold assembly 9. The push rod connectors 14 are fixed to one end of the two push rods 17. The push rod connectors 14 and the two push rods 17 form an open frame. This open frame moves between the two long guide plates 18, pushing the push rod connectors 14. The two push rods 17 push the other side of the side pressure rods 11, causing the side pressure rollers or side pressure blocks 16 to pass through the side through-groove 29 and press against the lead-clad aluminum wire 25. A material drop trough 23 is opened in the center of the worktable 2. After the lead-clad aluminum wire 25 is squeezed, the support side plate 4 moves from the center of the worktable 2 to both sides. The downward demolding mechanism 3 descends and inserts into the upper through hole 13, so that the lead-clad aluminum wire 25 falls from the fixed column 22 into the wire assembly grid 35 of the wire assembly tray 5. Several wire assembly grids 35 are arranged in the wire assembly tray 5 along the direction perpendicular to the worktable 2. The wire assembly tray 5 moves along the direction perpendicular to the worktable 2 through the lead screw. The end of the short guide rod 7 near the side mold assembly 9 is wedge-shaped; the other end of the push rod 17 is wedge-shaped.

[0039] like Figure 7 As shown, the pressing demolding mechanism 3 includes: a cylinder 31, a cylinder connector 32, a pressing crossbeam 33, and pressing columns 34. The upper end of the pressing crossbeam 33 is connected to the cylinder 31 through the cylinder connector 32. Several pressing columns 34 are fixed at the lower end of the pressing crossbeam 33. The cylinder 31 drives the pressing columns 34 to move downward. The pressing columns 34 enter the upper through hole 13 and press the lead-clad aluminum wire 25 into the wire assembly grid 35 of the wire assembly reel 5.

[0040] The supporting side plate 4, the long guide rod assembly 6, and the middle mold assembly 8 are all driven to move linearly by cylinders or linear propulsion devices. The assembly reel 5 is driven to move linearly by a motor mounted on a lead screw. All of them are controlled by a controller. The above control methods and transmission methods are all common designs of those skilled in the art.

[0041] The original position of the grid forming mold is that the middle mold assembly 8 is located between two short guide rods 7 at the other end of the worktable 2, the open frame composed of two push rods 17 and push rod connectors 14 is located at one end of the worktable 2, the wire assembly grid 35 of the wire assembly tray 5 is not filled with lead-clad aluminum wire 25, the two supporting side plates 4 are located in the center of the worktable 2, and the pressing demolding mechanism 3 is located at the top of the frame 1. The method of forming lead-clad aluminum wire using the grid forming mold of the present invention includes the following steps:

[0042] (a) Feeding the straight lead-clad aluminum wire into the grid forming mold.

[0043] A straight lead-clad aluminum wire 25 is fed into the ends of two side mold assemblies 9 near the guide wheel 26 in a direction perpendicular to the worktable 2, and the center of the lead-clad aluminum wire 25 is aligned with the center line of the worktable 2.

[0044] (ii) Bend the lead-clad aluminum wire into a U-shape.

[0045] like Figure 2 As shown, the middle mold assembly 8 is pushed out from the short guide rod 7 and inserted between the two side mold assemblies 9. The lead-clad aluminum wire 25 is sleeved on the fixing post 22 of the middle mold assembly 8 and bent into a U-shape.

[0046] (iii) The two opposite sides of the lead-clad aluminum wire are extruded into shape.

[0047] like Figure 3 The open frame, consisting of two push rods 17 and push rod connectors 14, is pushed along two long guide plates 18 toward the side mold assembly 9. The push rods 17 push the other side of several side pressure rods 11, causing them to move along the lower side groove 20 toward the center line of the worktable 2. The push rods 17 drive the side pressure rollers or side pressure blocks 16 to pass through the side through groove 29 of the middle mold assembly 8 and enter between the fixed columns 22 of the middle mold assembly 8, squeezing the two opposite sides of the lead-clad aluminum wire 25 together. After the lead-clad aluminum wire 25 is formed, the open frame consisting of the two push rods 17 and push rod connectors 14 returns to its original position.

[0048] (iv) The formed lead-clad aluminum wire falls from the workbench into the wire assembly reel.

[0049] Two supporting side plates 4 are pulled outward from both sides of the workbench 2, exposing the material drop chute 23 on the workbench 2. The cylinder 31 drives the downward pressing column 34 to move downward, passing through the upper through hole 13. The downward pressing column 34 presses against the two opposite sides of the lead-clad aluminum wire 25 where they are squeezed together. The lead-clad aluminum wire 25 falls off the fixed column 22 and enters a wire assembly grid 35 of the wire assembly reel 5. Driven by the lead screw, the wire assembly reel 5 moves one wire assembly grid 35 position in a direction perpendicular to the workbench 2, so that the wire assembly grid 35 facing the next material drop is not filled with lead-clad aluminum wire 25. The two supporting side plates 4 and the cylinder 31 return to their original positions.

[0050] The above description only discloses specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or modifications that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.

4. The plate grid forming mold as described in claim 3, characterized in that: At the end of the middle mold assembly (8) that enters the upper pressure plate (12), a guide wheel (26) is installed.

5. The plate grid forming mold as described in claim 4, characterized in that: A set of side pressure wheels or side pressure blocks (16) and side pressure rods (11) are also installed on the side mold assembly (9) near the guide wheel (26).

6. The plate grid forming mold as described in claim 5, characterized in that: The end of the short guide rod (7) near the side mold assembly (9) is wedge-shaped; the other end of the push rod (17) is wedge-shaped.

7. The grid forming mold as described in claim 6, characterized in that: The assembly tray (5) has several assembly grids (35) arranged in a direction perpendicular to the workbench (2).

8. A method for forming lead-clad aluminum wire using the grid forming mold as described in claim 7, wherein the original position of the grid forming mold is that the middle mold assembly (8) is located between two short guide rods (7) at the other end of the worktable (2), the open frame composed of two push rods (17) and push rod connectors (14) is located at one end of the worktable (2), the wire assembly grid (35) of the wire assembly disc (5) is not filled with lead-clad aluminum wire (25), the two supporting side plates (4) are located in the center of the worktable (2), and the pressing demolding mechanism (3) is located at the top of the frame (1), characterized in that: The method includes the following steps: (a) Feeding the straight lead-clad aluminum wire into the grid forming mold A straight lead-clad aluminum wire (25) is fed into the ends of two side mold assemblies (9) near the guide wheel (26) in a direction perpendicular to the worktable (2), and the center of the lead-clad aluminum wire (25) is aligned with the center line of the worktable (2). (ii) Bend the lead-clad aluminum wire into a U-shape. The middle mold assembly (8) is pushed out from the short guide rod (7) and inserted between the two side mold assemblies (9). The lead-clad aluminum wire (25) is looped on the fixing post (22) of the middle mold assembly (8) and bent into a U-shape. (iii) The two opposite sides of the lead-clad aluminum wire are extruded into shape. The open frame, consisting of two push rods (17) and push rod connectors (14), is pushed along two long guide plates (18) toward the side mold assembly (9). The push rods (17) push the other side of several side pressure rods (11) so that they move along the lower side groove (20) toward the center line of the worktable (2). The push rods (17) drive the side pressure rollers or side pressure blocks (16) to pass through the side through groove (29) of the middle mold assembly (8) and enter between the fixed columns (22) of the middle mold assembly (8), squeezing the two opposite sides of the lead-clad aluminum wire (25) together. After the lead-clad aluminum wire (25) is formed, the open frame consisting of two push rods (17) and push rod connectors (14) returns to its original position. (iv) The formed lead-clad aluminum wire falls from the workbench into the wire assembly reel. Two support side plates (4) are pulled outward from both sides of the workbench (2), exposing the material drop chute (23) on the workbench (2). The cylinder (31) drives the pressing column (34) to move downward, passing through the upper through hole (13). The pressing column (34) presses on the two opposite sides of the lead-clad aluminum wire (25) and squeezes them together. The lead-clad aluminum wire (25) falls off the fixed column (22) and enters a wire assembly grid (35) of the wire assembly reel (5). Driven by the screw, the wire assembly reel (5) moves one wire assembly grid (35) position in a direction perpendicular to the workbench (2), so that the wire assembly grid (35) facing the next material drop is not filled with lead-clad aluminum wire (25). The two support side plates (4) and the cylinder (31) return to their original positions.
