[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.
[0032] Example:
[0033] like Figures 1 to 9As shown, the present invention provides an automatic forming device for transformer copper leads, comprising a workbench 11, which provides a stable support platform for the operation of the entire device. A support base plate 12 is disposed above the workbench 11 and serves as the support base for numerous subsequent mechanisms. A support plate 13 is disposed on the support base plate 12, and a cotton clamp mechanism 14 and a roller assembly are disposed on the support plate 13. The rollers are neatly positioned on one side of the support plate 13, while the cotton clamp mechanism 14 is located at one end of the roller assembly. The copper leads are threaded through the cotton clamp mechanism 14 and the roller assembly. The cotton clamp mechanism 14 cleans, guides, and clamps the copper leads, while the roller assembly ensures linear transport of the copper leads, with the two mechanisms working in perfect harmony. A wire feed mechanism and a lead pre-bending mechanism are disposed at the other end of the roller assembly. The wire feed mechanism is located between the lead pre-bending mechanisms. The roller assembly, wire feed mechanism, and lead pre-bending mechanism are arranged in a straight line, ensuring smooth processing of the copper leads. Two sets of support plates 15 are mounted on the support base 12, arranged in sequence at one end of the wire feeding mechanism, providing additional support and positioning for the related mechanisms. A lead clamping mechanism is also mounted on the support base 12, with a lead pre-bending mechanism located between them. A lead flattening and cutting mechanism and a blanking mechanism are also located above the support base 12, both located to one side of the lead pre-bending mechanism. These mechanisms work together to complete the automated processing of the copper leads, and the entire process is controlled by a PLC.
[0034] like Figure 2 、 Figure 3As shown, the roller assembly primarily comprises a mounting frame 21, which is connected to the support plate 13 and provides stable support for the entire roller assembly. Multiple mounting chutes 22 are defined within the mounting chutes 22. Mounting sliders 23 are located within the mounting chutes 22. The slidable connection between the mounting sliders 23 and the mounting frame 21 allows the sliders to slide within the chutes 22. A first spring is also located within the mounting chutes 22. One end of the first spring is connected to the mounting frame 21, and the other end is connected to the mounting slider 23. This provides elastic support for the mounting slider 23 during sliding, ensuring stable sliding within a certain range and buffering external pressure fluctuations to a certain extent. A first roller 24 is located on the mounting slider 23, while multiple sets of second rollers 25 are located on one side of the mounting frame 21. The number of second rollers 25 exceeds the number of first rollers 24 and is neatly positioned below the first rollers 24. Copper wire leads are threaded between the multiple sets of first rollers 24 and the multiple sets of second rollers 25, enabling smooth, linear transport through the rolling motion of the rollers. A mounting block plate 26 is detachably provided on the top of the mounting frame 21. An adjustment hole 27 is provided on the mounting block plate 26 corresponding to the mounting slider 23. The adjusting bolt passes through the adjusting hole 27 and contacts the mounting slider 23, so that the operator can control the position of the mounting slider 23 by adjusting the bolt, and then adjust the position of the first roller 24 to meet different production requirements.
[0035] like Figure 2 、 Figure 4 、 Figure 9 As shown, the wire feeding mechanism includes a clamping seat 301, which is a key component for securing the copper sheet lead during the wire feeding process. A mounting platform 302 is provided above the support base 12, and a linear guide 303 is provided on the mounting platform 302. The linear guide 303 provides guidance for the movement of the clamping seat 301. The clamping seat 301 is located above the mounting platform 302, and a linear slide 304 is provided at its bottom. The linear guide 303 is clamped in the linear slide 304, thereby achieving a slidable connection between the clamping seat 301 and the linear guide 303, ensuring the stability and accuracy of the clamping seat 301 during movement.
[0036] A clamping groove 305 is provided on the clamping seat 301, and the copper sheet lead passes through this clamping groove 305, providing a basis for subsequent clamping operations. A wire clamping cylinder 306 is provided above the clamping seat 301, and a wire clamping block 307 is provided at the shaft end of the wire clamping cylinder 306. When the wire clamping cylinder 306 is working, the wire clamping block 307 will cooperate with the clamping seat 301 to firmly clamp the copper sheet lead between them, ensuring that the lead will not become loose or displaced during the wire feeding process. In addition, a first scale 308 is also provided on the mounting table 302. The first scale 308 is located on one side of the linear guide rail 303. The operator can intuitively observe and control the moving distance of the clamping seat 301 through the first scale 308, thereby realizing the control of the wire feeding length.
[0037] The wire feeding mechanism also includes a wire feeding cylinder 309, which is installed on one side of the support plate 13 and is the power source for wire feeding. The axial end of the wire feeding cylinder 309 is provided with a wire feeding plate 310, and a limiting block 311 is provided on one side of the wire feeding plate 310. A limiting groove 312 is provided on the clamping seat 301 corresponding to the limiting block 311. The limiting block 311 is clamped in the limiting groove 312, so that a stable connection is established between the wire feeding plate 310 and the clamping seat 301. A limiting hole 313 is provided on the support plate 15, and a limiting bolt 314 is passed through two groups of limiting holes 313. One end of the limiting bolt 314 can contact the clamping seat 301, which further limits and adjusts the moving range of the clamping seat 301, ensuring the accuracy and safety of the wire feeding process. The various components of the entire wire feeding mechanism work together to ensure that the copper sheet lead can be accurately and stably transported according to predetermined requirements.
[0038] like Figure 2 、 Figure 5 、 Figure 6 As shown, the lead pre-bending mechanism includes a rotating cylinder 41, and a plurality of fixed side plates 42 are arranged below the supporting base plate 12. The fixed side plates 42 are connected to each other to form a fixed frame with a stable structure. Two groups of fixed rods 43 are provided on this fixed frame, which provide stable support and guidance for subsequent components. Above the fixed frame is a fixed support plate 44, and the fixed rod 43 is passed through the fixed support plate 44, and the fixed support plate 44 and the fixed rod 43 are slidably connected. This allows the fixed support plate 44 to slide up and down smoothly on the fixed rod 43. The rotating cylinder 41 is installed on the fixed support plate 44, and a lifting cylinder 45 is provided at the bottom of the fixed frame, and the shaft end of the lifting cylinder 45 is connected to the fixed support plate 44. When the lifting cylinder 45 is working, it can push the fixed support plate 44 to slide upward along the fixed rod 43.
[0039] A rotating shaft 46 and a wire bending block 47 are located at the top of the rotating cylinder 41. The shaft 46 is located in the center of the cylinder 41, and the wire bending block 47 is located to one side of the shaft 46. When the copper lead is delivered to this location, the bending block 47 and the rotating shaft 46 can both contact the copper lead. Driven by the rotating cylinder 41, the rotating shaft 46 begins to rotate, and the copper lead is bent along the rotating shaft 46 to form the preset shape. The entire process, through the coordinated operation of the precise mechanical structure and the cylinder, ensures the accuracy and stability of the lead pre-bending.
[0040] The lead clamping mechanism includes a clamping cylinder 51 and a fixed shaping block 52. A baffle 16 is provided on the supporting base plate 12, and the clamping cylinder 51 is installed on one side of the baffle 16. The fixed shaping block 52 is located at one end of the clamping cylinder 51 and is installed on two sets of supporting plates 15, providing stable support for the entire clamping process. A V-shaped groove 53 is provided on the fixed shaping block 52, and the copper sheet lead passes through this V-shaped groove 53. A correction block 54 and a wire pressing block 55 are provided at one end of the clamping cylinder 51. A through groove 56 is provided on the fixed shaping block 52 corresponding to the correction block 54. When the clamping cylinder 51 is working, the correction block 54 can position the lead through the through groove 56. The wire pressing block 55 can fit into the V-shaped groove 53 and apply appropriate pressure to the lead during the clamping process. Furthermore, two sets of guide pins 57 are located on one side of the fixed shaping block 52. These, in conjunction with the wire pressing block 55, further ensure the positional accuracy of the wires during the pressing process. A detection block 58 is mounted on one of the support plates 15, located adjacent to the wire feeding mechanism, through which the copper wires pass. If a wire feeding anomaly occurs, the detection block 58 promptly detects the problem, halting the equipment and preventing further errors, thereby ensuring the reliability of the entire production process.
[0041] like Figure 2 、 Figure 7 、 Figure 8As shown, the lead flattening and cutting mechanism includes a pressure cylinder 61. An assembly plate 17 is located atop the workbench 11. The pressure cylinder 61 is securely mounted on the assembly plate 17, with its shaft end facing downward, providing stable vertical pressure for subsequent movements. A lower support plate 62 is detachably mounted on the support base 12, and an upper support plate 63 is located above the lower support plate 62. Multiple sets of guide shafts 64 are provided on the lower support plate 62. The upper support plate 63 has guide holes corresponding to the guide shafts 64, and the guide shafts 64 are inserted into the guide holes, enabling a slidable connection between the upper support plate 63 and the guide shafts 64. This ensures stability and precision during the upward and downward movement of the upper support plate 63. The shaft end of the pressure cylinder 61 contacts the upper support plate 63, providing power for its upward and downward movement. Multiple sets of second springs are also located between the upper and lower support plates 63 and 62, and are sleeved around the guide shafts 64. On the one hand, they assist the upper plate 63 in quickly and smoothly returning to its initial position when the pressure cylinder 61 retracts. On the other hand, during the entire flattening and cutting process, the springs act as a buffer, ensuring a smoother downward movement of the upper plate 63 and preventing unnecessary impact on the equipment and copper leads. Furthermore, a second scale is provided on one side of the lower plate 62, allowing the operator to visually observe and adjust the positions of relevant components.
[0042] An upper cutter 65 is provided on the upper support plate 63, and a lower cutter 66 is provided on the lower support plate 62 to correspond to the upper cutter 65. The copper lead is positioned between the upper and lower cutters 65 and 66, and the two cutters cooperate to cut the lead. Specifically, an elastic pressure block 67 is provided at the bottom of the upper cutter 65. Before cutting, the elastic pressure block 67 contacts and compresses the copper lead, ensuring a stable position during cutting. Furthermore, an upper die 68 is provided on the upper support plate 63, and a lower die 69 is provided on the lower support plate 62 to correspond to the upper die 68. One end of the copper lead is positioned between the upper and lower dies 68 and contacts the lower die 69, flattening the lead.
[0043] The blanking mechanism includes a blanking cylinder 71. A mounting plate 72 is mounted on one side of the lower cutter 66 and the lower die 69. The blanking cylinder 71 is positioned on one side of the lower cutter 66 and securely mounted on the mounting plate 72. A first blanking block 73 is mounted on one side of the mounting plate 72 and is attached to the shaft end of the blanking cylinder 71. This block is a key component in the blanking operation.
[0044] A second blanking block 74 is located on one side of the first blanking block 73. This second blanking block 74 has a unique hook shape and is positioned between the lower cutter 66 and the lower die 69. The copper leads are threaded through the second blanking block 74. When processing is complete, the blanking cylinder 71 activates, pushing the first blanking block 73, which in turn drives the second blanking block 74. Below the blanking cylinder 71 is a blanking chute 75. A magazine 76 is located on one side of the workbench 11, and its height is lower than that of the support base 12. The blanking chute 75 is connected to the support base 12 at one end and in contact with the magazine 76 at the other end. The blanking chute 75 is tilted and installed between the support base 12 and the magazine 76. This tilted design utilizes gravity. After the second blanking block 74 removes the copper leads, they slide freely down the blanking chute 75 into the magazine 76, automating the blanking process and improving the efficiency and continuity of the entire production process.
[0045] The specific usage and function of this embodiment are as follows:
[0046] During operation, the copper lead wire is passed through the cotton clamp mechanism 14 and the roller assembly. The cotton clamp mechanism 14 then begins to clean, guide, and initially clamp the copper lead wire. The wire feeding mechanism is activated, and the wire feeding cylinder 309 activates, driving the wire feeding plate 310 to move. The limit block 311 cooperates with the upper limit slot 312 on the clamping seat 301, causing the clamping seat 301 to move along the linear guide 303. The wire clamping cylinder 306 then activates in a timely manner, and the wire clamping block 307 cooperates with the clamping seat 301 to clamp the copper lead wire, feeding the wire to the desired length. The operator can observe the wire feeding length using the first scale 308. When the desired length is reached, the wire feeding cylinder 309 and the wire clamping cylinder 306 operate according to the program, completing the wire feeding.
[0047] After the wire feeding is completed, the lead pre-bending mechanism starts to work. The rising cylinder 45 pushes the fixed support plate 44 to slide upward along the fixed rod 43, and the rotating cylinder 41 rises accordingly. When the copper sheet lead falls into the bending block 47, the rotating cylinder 41 rotates clockwise. Under the action of the rotating shaft 46 and the bending block 47, the copper sheet lead is bent into a preset shape along the rotating shaft 46. Then the rotating cylinder 41 is reset and the rising cylinder 45 descends. Then, the lead clamping mechanism starts. The clamping cylinder 51 extends out, and the correction block 54 positions the lead through the through groove 56 on the fixed shaping block 52. The wire pressing block 55 fits into the V-groove 53 and cooperates with the two sets of guide pins 57 to press the bent lead. If there is an abnormality in the wire feeding, the detection block 58 can detect the problem and stop the equipment.
[0048] The lead flattening and cutting mechanism operates. The pressure cylinder 61 works, pushing the upper support plate 63 to slide downward along the guide shaft 64. The elastic pressure block 67 first contacts the copper sheet lead and presses it tightly. Then the upper cutter 65 and the upper die 68 work to cut and flatten the lead. After the operation is completed, the pressure cylinder 61 resets after maintaining pressure for 3 seconds, and the upper support plate 63 returns to its initial position under the action of the second spring. Finally, the blanking mechanism works. The blanking cylinder 71 is pushed out, pushing the first blanking block 73 to move, driving the hook-shaped second blanking block 74 to move. Since the copper sheet lead is inserted into the second blanking block 74, the processed copper sheet lead can be brought out. Under the action of gravity, the lead slides along the inclined blanking trough 75 into the material box 76, completing the entire processing flow.
[0049] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
