Description

Technical Field

[0002] In the production process of transformers, the forming processing of copper sheet leads is a critical part. Transformer copper sheet leads are usually thin-sheet lead parts made of copper. They are used to connect different windings inside the transformer and to achieve electrical connection with external circuits. They are vital in transformers.

[0003] Before the copper lead is installed in the transformer, it needs to be formed in advance to ensure its accurate installation in the transformer and achieve good electrical connection function; however, traditional copper lead forming processing usually relies on manual operation or the use of simple auxiliary equipment, and requires a series of processes such as lead feeding, bending, flattening, cutting and blanking, which requires a lot of time and energy, increases labor costs, and reduces work efficiency; at the same time, simple auxiliary equipment also requires manual operation.

A wire feeding mechanism and a lead pre-bending mechanism are arranged at the other end of the roller group. The wire feeding mechanism is located between the lead pre-bending mechanism. The roller group, the wire feeding mechanism and the lead pre-bending mechanism are arranged in a straight line in sequence. This arrangement ensures the smoothness of the copper sheet leads during the processing. Two groups of support plates 15 are arranged on the support base plate 12, and the two groups of support plates 15 are arranged in sequence at one end of the wire feeding mechanism, providing additional support and positioning for the relevant mechanisms. A lead clamping mechanism is also arranged on the support base plate 12, and the lead pre-bending mechanism is located between the lead clamping mechanisms. A lead flattening and cutting mechanism and a blanking mechanism are also arranged above the support base plate 12, both of which are located on one side of the lead pre-bending mechanism. Each mechanism cooperates with each other to complete the automatic processing flow of the copper sheet lead. At the same time, the entire process is controlled by PLC.

[0034] like Figure 2 , Figure 3As shown, the roller group mainly includes a mounting frame 21, which is connected to the support plate 13 to provide stable support for the entire roller group. Multiple groups of mounting chutes 22 are provided on the mounting frame 21. A mounting slide block 23 is provided in the mounting chutes 22, and the slidable connection between the mounting slide block 23 and the mounting frame 21 enables the slide block to slide in the mounting chutes 22. A first spring is also provided in 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 slide block 23, so that the mounting slide block 23 can obtain elastic support during the sliding process, ensuring the stable sliding of the slide block within a certain range, and can buffer the external pressure changes to a certain extent. A first roller 24 is provided on the mounting slide block 23, and multiple groups of second rollers 25 are provided on one side of the mounting frame 21, the number of the second rollers 25 is greater than the number of the first rollers 24, and they are neatly located below the first rollers 24. The copper sheet lead is passed between the multiple groups of first rollers 24 and the multiple groups of second rollers 25, and a smooth linear conveying is achieved through the rolling of the rollers. A mounting block plate 26 is detachably provided on the top of the mounting frame 21, and 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 , Fig. 9 As shown, the wire feeding mechanism includes a clamping seat 301, which is a key component for fixing the copper sheet lead during the wire feeding process. A mounting platform 302 is arranged above the supporting base plate 12, and a linear guide rail 303 is arranged on the mounting platform 302, and the linear guide rail 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 groove 304 is provided at the bottom thereof, and the linear guide rail 303 is clamped in the linear slide groove 304, thereby realizing a slidable connection between the clamping seat 301 and the linear guide rail 303, and ensuring the stability and accuracy of the clamping seat 301 during the movement.

[0036] A clamping groove 305 is provided on the clamping seat 301, and the copper sheet lead wire passes through this clamping groove 305, which provides a basis for the subsequent clamping operation. A clamping cylinder 306 is arranged above the clamping seat 301, and a clamping block 307 is arranged at the shaft end of the clamping cylinder 306. When the clamping cylinder 306 is working, the clamping block 307 will cooperate with the clamping seat 301 to firmly clamp the copper sheet lead wire between them, ensuring that the lead wire will not loosen or move 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. A wire feeding plate 310 is provided at the axial end of the wire feeding cylinder 309, 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, and 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.

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 wire pre-bending mechanism includes a rotating cylinder 41, and a plurality of fixed side plates 42 are arranged below the supporting base plate 12, and 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 arranged 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 inserted into the fixed support plate 44, and the fixed support plate 44 and the fixed rod 43 are slidably connected. The fixed support plate 44 can slide up and down smoothly on the fixed rod 43. The rotating cylinder 41 is installed on the fixed support plate 44, and a rising cylinder 45 is arranged at the bottom of the fixed frame, and the shaft end of the rising cylinder 45 is connected to the fixed support plate 44. When the rising 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 provided at the top of the rotating cylinder 41. The rotating shaft 46 is located at the center of the rotating cylinder 41, and the wire bending block 47 is located on one side of the rotating shaft 46. When the copper sheet lead is transported here, the wire bending block 47 and the rotating shaft 46 can both contact the copper sheet lead. Driven by the rotating cylinder 41, the rotating shaft 46 starts to rotate, and the copper sheet lead bends along the rotating shaft 46 to form a preset shape. The entire process ensures the accuracy and stability of the lead pre-bending through the coordinated work of the precise mechanical structure and the cylinder.

[0040] The lead clamping mechanism includes a clamping cylinder 51 and a fixed shaping block 52. A baffle 16 is provided on the support 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 groups of support 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 with the V-shaped groove 53, and apply appropriate pressure to the lead during the clamping process. At the same time, two groups of guide pins 57 are also arranged on one side of the fixed shaping block 52, which cooperate with the wire pressing block 55 to further ensure the position accuracy of the lead wire during the pressing process. A detection block 58 is installed on one group of support plates 15.

When the wire feeding is abnormal, the detection block 58 can detect the problem in time, stop the equipment from running, and avoid further expansion of the error, 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 provided on the top of the workbench 11. The pressure cylinder 61 is stably mounted on the assembly plate 17, and its shaft end faces downward, providing a stable vertical pressure for subsequent actions.

A plurality of guide shafts 64 are provided on the lower bearing plate 62. A guide hole is provided on the upper bearing plate 63 corresponding to the guide shaft 64, and the guide shaft 64 is inserted into the guide hole, so that the upper bearing plate 63 and the guide shaft 64 are slidably connected. The stability and accuracy of the upper bearing plate 63 in the process of moving up and down are guaranteed. At the same time, the shaft end of the pressure cylinder 61 contacts the upper bearing plate 63, providing power for the upper bearing plate 63 to move up and down. A plurality of second springs are also provided between the upper bearing plate 63 and the lower bearing plate 62, and the second springs are sleeved on the guide shaft 64. On the one hand, they can assist the upper bearing plate 63 to return to the initial position quickly and smoothly when the pressure cylinder 61 retracts; on the other hand, during the entire flattening and cutting process, the springs can play a buffering role, making the downward pressing action of the upper bearing plate 63 more stable, avoiding unnecessary impact on the equipment and copper sheet leads. In addition, a second scale is set on one side of the lower bearing plate 62, through which the operator can intuitively observe and adjust the position of related 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 corresponding to the upper cutter 65. The copper sheet lead is located between the upper cutter 65 and the lower cutter 66, and the two cooperate to achieve the function of cutting the lead. In particular, an elastic pressing block 67 is provided at the bottom of the upper cutter 65. Before cutting, the elastic pressing block 67 first contacts the copper sheet lead and presses it tightly to ensure that the lead position is stable during cutting. At the same time, an upper pressing die 68 is provided on the upper support plate 63, and a lower pressing die 69 is provided on the lower support plate 62 corresponding to the upper pressing die 68. One end of the copper sheet lead is located between the upper pressing die 68 and the lower pressing die 69, and contacts the lower pressing die 69 to achieve the flattening operation of the lead.

[0043] The blanking mechanism includes a blanking cylinder 71, and a mounting plate 72 is installed on one side of the lower cutter 66 and the lower die 69. The blanking cylinder 71 is located on one side of the lower cutter 66 and is stably mounted on the mounting plate 72. A first blanking block 73 is provided on one side of the mounting plate 72. The first blanking block 73 is installed on the shaft end of the blanking cylinder 71, and it is one of the key components of the blanking action.

[0044] A second material removal block 74 is provided on one side of the first material removal block 73. The second material removal block 74 is in a unique hook shape and is located between the lower cutter 66 and the lower die 69. The copper sheet lead is inserted into the second material removal block 74. When the processing is completed, the material removal cylinder 71 starts to work, pushing the first material removal block 73 to move, thereby driving the second material removal block 74 to move. A material removal chute 75 is provided below the material removal cylinder 71, and a material box 76 is provided on one side of the workbench 11. The height of the material box 76 is lower than the height of the supporting bottom plate 12. One end of the material removal chute 75 is connected to the supporting bottom plate 12, and the other end is in contact with the material box 76, and the material removal chute 75 is installed between the supporting bottom plate 12 and the material box 76 in an inclined shape. This inclined design utilizes the principle of gravity. When the second material removal block 74 brings out the copper sheet lead, the lead can slide freely along the material removal chute 75 into the material box 76, realizing the automation of material removal during the production 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] When in use, the copper sheet lead is passed through the cotton clamp mechanism 14 and the roller group, and the cotton clamp mechanism 14 starts to clean, guide and preliminarily clamp the copper sheet lead. The wire feeding mechanism is started, and the wire feeding cylinder 309 works, driving the wire feeding plate 310 to move. Through the cooperation of the limit block 311 and the upper limit groove 312 of the clamping seat 301, the clamping seat 301 moves along the linear guide 303, and the wire clamping cylinder 306 works in time, and the wire clamping block 307 cooperates with the clamping seat 301 to clamp the copper sheet lead and feed the wire according to the predetermined length. The operator can observe the wire feeding length through the first scale 308. When the required length is reached, the wire feeding cylinder 309 and the wire clamping cylinder 306 act according to the program to complete 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, and then the rotating cylinder 41 is reset, and the rising cylinder 45 descends. Then, the lead clamping mechanism is started. 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 with the V-groove 53 and cooperates with 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 plate 63 to slide downward along the guide shaft 64. The elastic pressure block 67 first contacts the copper sheet lead and presses it, and 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 plate 63 returns to the 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 and main features of the present invention and the 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.
