At the beginning, the inner mold and the down-pressing assembly are located at the rear of the frame, the forming push rod assembly is located at the front of the frame, and the wire assembly reel is located at the initial position on the right side of the conveyor line. When a single wire enters the conveying channel formed by the support plate, which is slightly larger than the wire diameter, and the wire detection sensor detects that the incoming wire size meets the specified length, the tool drive drives the tool to cut the wire, and the lifting plate of the wire lifting assembly pushes the cut wire out of the conveying channel.

DETAILED DESCRIPTION

[0067] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0068] Example 1

[0069] like Figure 1-2 As shown, this embodiment discloses a battery grid wire forming device, comprising: a frame 1, a conveyor 2, a battery grid wire cutting mechanism, an inner mold and a downward pressing assembly 5, an outer mold assembly 6, a forming push rod assembly 7, and a wire assembly drum 9, wherein the frame 1 is welded into an integral structure by profiles and plates and is provided with mounting points for other components; the conveyor 2 is arranged at a set position below the outer mold assembly 6 and has no connection with the frame 1, and the wire assembly drum 9 can move left and right under the drive of the conveyor 2. The battery grid wire cutting mechanism and the wire lifting assembly 4 are fixed to two longitudinal beams at the lower rear of the frame 1. The battery grid wire cutting mechanism is used to cut the wire to a specified length, thereby improving the dimensional accuracy of subsequent bending and forming. The inner mold and the downward pressing assembly 5 act as an inner mold to shape the wire from a U-shaped wire A1 into an arc-shaped wire A2, and press the formed arc-shaped wire A2 into the wire assembly drum 9. The assembly drum 9 is set on the conveyor 2 through the assembly drum positioning and stepping component 8. The assembly drum 9 serves as a carrier for the curved wire A2. Under the action of the assembly drum positioning and stepping component 8, the assembly drum 9 performs lifting and stepping actions. After each curved wire A2 is pressed into the assembly drum 9, the assembly drum 9 steps and moves the same distance until all the grids of the assembly drum 9 are filled with the curved wire A2.

[0070] Specifically, if Figure 3 As shown, the battery grid wire cutting mechanism includes: a wire lifting component 4, a wire detection sensor 34 and a wire cutting component 3. The wire cutting component 3 is arranged on the wire lifting component 4 and is used to cut the wire. The wire cutting component 3 includes: a tool support frame 33, a tool drive 32 and a tool 31. The tool support frame 33 is arranged on the side of the wire lifting component 4 close to the incoming wire, and the wire detection sensor 34 is arranged on the other side of the wire lifting component 4. When the wire detection sensor 34 detects that the wire is in place, the incoming wire is stopped, and the tool drive 32 drives the tool 31 to cut the wire.

[0071] The wire lifting assembly 4 includes: a wire lifting support frame 41, a lifting drive 42, a lifting plate 44, and a support plate 45. The support plates 45 are provided in two pieces. Both support plates 45 are bent and formed from steel plates and fixed to the wire lifting support frame 41. The bend forms a conveying channel 451 slightly larger than the diameter of the wire to facilitate the feeding of the wire. A bending channel 452 is left between the two support plates 45, which serves as a channel for the inner mold and the pressing assembly 5 to move back and forth. The wire lifting drive 42 is fixed in the middle of the wire lifting support frame 41. The lifting plate 44 is set at the output end of the wire lifting drive 42. The two ends of the lifting plate 44 are mounted on both sides of the wire lifting support frame 41 through guide columns 43. Under the action of the wire lifting drive 42, the lifting plate 44 can move up and down in the conveying channel 451, pushing the cut wire out of the conveying channel 451, facilitating the next step of bending the wire. The support plate 45 acts as a support plate for the wire during the bending process, preventing it from falling. The exit of the bending channel 452 is provided with three sets of forming auxiliary wheels 46, specifically three sets of rollers arranged in descending order, to assist in bending the wire into a U-shape. These wheels act as a buffer, provide position limiting guidance, prevent scratches, and assist in the bending process.

[0072] like Figure 4-5 As shown, the inner mold support 51 of the inner mold and hold-down assembly 5 is welded from sheet metal and mounted on two inner mold support drivers 55. Driven by these drivers, the two inner mold support drivers 55 are fixedly connected to the upper surfaces of the two longitudinal beams located above the rear portion of the frame 1. As the inner mold and hold-down assembly 5 moves forward, the three sets of auxiliary forming wheels 46 bend the wire into a U-shape and feed it into the U-shaped channel of the outer mold assembly 6. The downward driving member 54 is installed on the top of the inner mold bracket 51, the inner mold 52 is fixedly connected to the inner mold bracket 51, and the stamping sleeve 53 is composed of a component that can move as a whole through the sleeve connecting plate 531, the driving member connecting plate 532, the connecting column 533, and the tail stamping rod 534. The middle part of the stamping sleeve 53 is a circular channel slightly larger than the inner mold 52, and is coaxial with the inner mold 52. The driving member connecting plate 532 is connected to the downward driving member 54. The entire stamping sleeve 53 can move up and down under the action of the downward driving member 53 to stamp the formed wire into the grid of the assembly reel 9.

[0073] like Figure 6-8As shown, the outer mold assembly 6 includes: a basic connecting plate 61, a sliding unit 62, a side pressure wheel 63, an outer mold reset assembly 64, a contact wheel 65, a head stopper 66, a tail stopper 67, and a support door panel 68. The four corners of the basic connecting plate 61 of the outer mold assembly 6 are fixedly connected to the lower surfaces of the two longitudinal beams above the rear of the frame 1, and the middle of the basic connecting plate 61 is a U-shaped channel, which facilitates the inner mold and the down-pressing assembly 5 to move back and forth in the channel. The sliding units 62 are respectively arranged on the left and right sides of the basic connecting plate 61. The fixed slide rails 622 of the sliding unit 62 are fixedly connected to the basic connecting plate 61. The sliding plate 621 and the fixed slide rails 622 can slide relative to each other. A side pressure wheel 63 is installed on the sliding plate 621 near the middle of the basic connecting plate 61. A spring hanging shaft 641 and a contact wheel 65 are installed on both sides of the sliding plate 621 near the basic connecting plate 61. The spring hanging shaft 641 is located above the basic connecting plate 61, and the contact wheel 65 is located below the basic connecting plate 61. A straight hole is provided at the position corresponding to the spring hanging shaft 641, and the spring hanging shaft 641 is connected to the spring 62 through the straight hole. The fixed hook shaft 643 is fixed to the two side edges of the upper surface of the basic connecting plate 61. One side of the spring 62 is connected to the spring hanging shaft 641, and the other side is connected to the fixed hook shaft 643; in the initial state, the spring hanging shaft 641 is tightened under the action of the spring 62, driving the sliding plate 621 and the side pressure wheel 63 to move to both sides of the basic connecting plate 61, leaving space for the inner mold and the downward pressure component 5 to enter the U-shaped channel in the middle of the basic connecting plate 61.

[0074] like Figure 11 As shown, the forming push rod assembly 7 is arranged at the front of the frame 1 and includes a push rod driving member 71, a push rod 72, and a push rod slide 73. The push rod driving member 71 and the push rod slide 73 are fixed to the connecting plate provided on the frame 1. The push rod 72 is a fork-shaped structure, and the ends of the forks on both sides are closed to guide the contact wheel 65, so that the inner side surface of the push rod 72 sequentially presses the contact wheel 65. The middle position of the push rod 72 is connected to the push rod driving member 71, and the forks on both sides of the push rod 72 are connected to the push rod slide 73. Driven by the push rod driving member 71, the push rod 72 can move in the front-back direction. When the push rod 72 moves backward, the inner side surface of the push rod 72 sequentially presses the contact wheel 65, and the contact wheel 65 drives the side pressure wheel 63 on the sliding plate 621 to move closer to the middle of the base connecting plate 61.

[0075] like Figure 9-10As shown, during forming, the inner mold bracket 51 moves from back to front under the drive of the inner mold bracket driving member 55, driving the cut wire into the U-shaped channel in the middle of the basic connecting plate 61. When entering, it is guided and buffered by the three sets of forming auxiliary wheel groups 64, and finally the wire is bent into a U shape. The push rod 72 moves from front to back under the action of the push rod driving member 71. When the push rod 72 moves backward, the inner side surface of the fork arm of the push rod 72 squeezes the contact wheel 65 in turn, and the contact wheel 65 drives the side pressure wheel 63 on the sliding plate 621 to move closer to the middle of the basic connecting plate 61, thereby further bending the single wire bent into a U shape into an arc state, and is kept between the inner mold and the side pressure wheel 63 under the squeezing of the inner mold and the side pressure wheel 63 to form an arc-shaped wire A2.

[0076] like Figure 12 As shown, the center area of ​​the assembly drum 9 is provided with multiple bosses, the positions of which are set according to the layout dimensions of the grid. Four bushings 91 are provided on the left and right sides of the assembly drum 9. The positions and dimensions of the four bushings 91 are the same as the positions of the four positioning pins 87 of the assembly drum positioning and stepping assembly 8. The assembly drum positioning and stepping assembly 8 drives the assembly drum 9 to move left and right and up and down.

[0077] Specifically, if Figure 13-15 As shown, the assembly reel positioning and stepping component 8 includes: a supporting bracket 81, a stepping drive 82, an assembly reel slide 83, an assembly reel lifting bracket 84, a lifting bracket drive 85, a guide sleeve 86 and a positioning pin 87. The supporting bracket 81 of the assembly reel positioning and stepping component 8 is welded into a frame structure by profiles and plates. The four lower corners of the supporting bracket 81 are connected to the assembly reel slide 83, and the connecting plate at the lower middle position is connected to the stepping drive 82 and the lifting bracket drive 85. The assembly reel positioning and stepping component 8 is arranged on a rectangular plate at the lower rear of the frame 1, and the stepping drive 82 and the assembly reel slide 83 are fixedly connected to the rectangular plate. Guide sleeves 86 are installed at the four corners of the upper portion of the support bracket 81. The assembly drum lifting bracket 84 is a rectangular frame welded part with four positioning pins 87 installed at the four corners. These pins cooperate with the guide sleeves 86 to form a sliding pair that can play a guiding role. The middle weld plate of the assembly drum lifting bracket 84 is connected to the joint of the lifting bracket driver 85. Under the action of the stepping driver 82, the support bracket 81, the assembly drum lifting bracket 84, and the lifting bracket driver 85 can move as a whole in the left and right directions, without any relative movement between the three in the left and right directions. Under the action of the lifting bracket driver 85, the assembly drum lifting bracket 84 and the positioning pins 87 can move in the up and down directions. Initially, the assembly drum 9 moves on the conveyor 2. When it moves to the designated position, the assembly drum lifting bracket 84 and the positioning pins 87 move upward. The four positioning pins 87 are inserted into the four bushings 91 of the assembly drum 9, positioning the assembly drum 9 and lifting it to the set height.

[0078] The assembly drum 9 serves as a carrier for the curved wires. Under the action of the assembly drum positioning and stepping component 8, it performs lifting and stepping actions. After each curved wire is pressed into the assembly drum 9, the assembly drum moves in steps the same distance until all grids of the assembly drum 9 are filled with curved wires.
