[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0044] Please see Figure 1-10 This utility model provides a technical solution: a transformer wire bending device, including a mounting frame 1, and further including: a support unit 3, symmetrically arranged on the mounting frame 1, for supporting the transformer wire 5; a bending unit 2, which is liftably arranged on the mounting frame 1 and located above the support unit 3, for bending the wire 5 on the support unit 3; and an adjustment unit 4, which is arranged on the mounting frame 1 and connected to the support unit 3, for adjusting the installation position of the support unit 3 on the mounting frame 1.
[0045] It should be noted that during operation, the transformer wire 5 to be bent is inserted between the support unit 3 and the bending unit 2, and the bending point is aligned with the bending unit 2. Then, the bending unit 2 is activated, causing it to move on the mounting frame 1 to compress and bend the wire 5 on the support unit 3. The adjustment unit 4 can adjust the position of the support unit 3 on the mounting frame 1, thereby changing the distance between the support unit 3 and the bending unit 2. This allows for bending of wires 5 of different sizes and with different bending angles. The bending unit 2 can be raised and lowered on the mounting frame 1. Operators can control the raising and lowering of the bending unit 2 to perform the bending operation on the wire 5. This design makes the bending action more precise and controllable, and can be adjusted according to different bending angles and force requirements, reducing the possibility of damage to the wire 5 or unqualified bending due to improper operation.
[0046] In one embodiment, the support unit 3 includes: a connecting shaft 31, which is disposed on the adjustment unit 4 and fixedly connected to the adjustment unit 4 by a nut 32; a second support roller 35, which is sleeved on the connecting shaft 31 and is used to support the cylindrical wire 5; a first support roller 33, which is sleeved on the second support roller 35 and is used to support the square wire 5; and a fixing member 34, which is disposed on the first support roller 33 and is used to fix the first support roller 33 and the second support roller 35. The connecting shaft 31 is fixed to the adjustment unit 4 by the nut 32, and the second support roller 35 is rotatably sleeved on the connecting shaft 31, so that the second support roller 35 can rotate on the connecting shaft 31 when the bending unit 2 bends the wire 5.
[0047] This design is for reference. Figure 1-10 The first support roller 33 is fitted onto the second support roller 35, forming a unique combined structure. The second support roller 35 is specifically designed to support the round tubular wire 5, while the first support roller 33 supports the square wire 5. This design allows the support unit 3 to simultaneously accommodate both round and square transformer wires 5, greatly improving the versatility of the device. It eliminates the need to replace different support equipment for different shapes of wires 5, reducing equipment procurement and management costs for enterprises. The first support roller 33 and the second support roller 35 are fixed together by the fastener 34. When it is necessary to switch from supporting square wires 5 to supporting cylindrical wires... When wire 5 (or vice versa), the operator only needs to loosen the fixing part 34, adjust the corresponding support roller to the appropriate position or perform the necessary replacement operation. This operation method is simple and quick, which can greatly shorten the production preparation time and improve production efficiency. The connecting shaft 31 is fixedly connected to the adjusting unit 4 through the nut 32, which makes the installation and removal of the support unit 3 on the mounting frame 1 very convenient. During equipment installation, debugging or maintenance, the operator can easily remove or install the support unit 3 from the adjusting unit 4, which facilitates the inspection, maintenance and replacement of the support unit 3 and reduces the difficulty and complexity of operation.
[0048] In one embodiment, the fixing member 34 includes: a fixing plate 341 disposed on the side of the first support roller 33 away from the mounting frame 1; and a fixing bolt 342 disposed on the fixing plate 341 for fixing the fixing plate 341 to the second support roller 35.
[0049] This design is for reference. Figure 5 ,as well as Figure 2The fixing plate 341 is located on the side of the first support roller 33 away from the mounting frame 1. The fixing plate 341 is fixedly connected to the second support roller 35 by fixing bolts 342. This design can provide a reliable connection between the first support roller 33 and the second support roller 35. During the bending process, the wire 5 will be subjected to a large force. The fixing part 34 can effectively prevent relative displacement or loosening between the first support roller 33 and the second support roller 35, ensuring that the two always maintain a tight connection, thereby providing stable support for the wire 5 and ensuring the smooth progress of the bending operation.
[0050] In one embodiment, the first support roller 33 is provided with a limiting block 331 at intervals inside, and the second support roller 35 is provided with a limiting groove 3501 for installing the limiting block 331.
[0051] This design is for reference. Figure 7 ,as well as Figure 8 Limiting blocks 331 are spaced apart inside the first support roller 33, and corresponding limiting grooves 3501 are opened on the second support roller 35. When the first support roller sleeve 33 is placed on the second support roller 35, the limiting blocks 331 are embedded in the limiting grooves 3501. This design can effectively limit the relative rotation between the first support roller 33 and the second support roller 35, ensuring that the two always maintain synchronous rotation or relative static state during the bending process, thereby providing stable support for the wire 5 and avoiding uneven force on the wire 5 due to the relative rotation of the support rollers, which would affect the bending quality.
[0052] In one embodiment, the second support roller 35 has a mounting groove 3502 for placing the wire 5.
[0053] This design is for reference. Figure 5 ,as well as Figure 6 The arc shape of the mounting groove 3502 provides a clear placement position for the wire 5. Before the bending operation, the operator can accurately embed the wire 5 into the mounting groove 3502 to prevent the wire 5 from rolling or shifting randomly on the support roller, thereby accurately determining the initial position of the wire 5 and providing a reliable reference for subsequent bending operations. This ensures that the bending position is accurate and greatly improves the bending accuracy of the wire 5.
[0054] In one embodiment, the adjustment unit 4 includes: a mounting plate 41 disposed on both sides of the mounting bracket 1; and positioning holes 42 formed at equal angles on the mounting plate 41 for mounting the connecting shaft 31.
[0055] This design is for reference. Figure 1-6 ,as well as Figure 8-10The mounting plate 41 has positioning holes 42 at equal angles. This design allows the connecting shaft 31 to be installed at multiple different angle positions, thereby achieving precise adjustment of the installation angle of the support unit 3. When facing different bending requirements or special-shaped wires 5, the operator can select the appropriate positioning hole 42 to install the connecting shaft 31 according to the actual situation, ensuring that the wire 5 receives the best support during the bending process and improving bending accuracy.
[0056] In one embodiment, the bending unit 2 includes: a power component 21, disposed at the top of the mounting frame 1; a control switch 22, disposed on the power component 21, for controlling the switching of the power component 21; a lifting block 23, disposed at the power output end of the power component 21 and slidably disposed on the mounting frame 1; a mounting shaft 24, disposed on the lifting block 23; and a pressing roller 25, sleeved on the mounting shaft 24, for pressing the wire 5. The power component 21 includes, but is not limited to, hydraulic cylinder electric push rods and air cylinders. The mounting frame 1 has a moving groove 101 for the lifting block 23 to move.
[0057] This design is for reference. Figure 1-4 ,as well as Figure 9-10 By controlling the switch 22, the operator can turn the power component 21 on or off according to the actual production needs, thereby flexibly controlling the start and end time of the bending operation. The power component 21 provides power to drive the lifting block 23 to slide on the mounting frame 1, which in turn drives the mounting shaft 24 and the extrusion roller 25 to move up and down. When the extrusion roller 25 moves downward, it can apply pressure to the wire 5 placed on the support unit 3 to achieve bending of the wire 5. Since the lifting block 23 slides on the mounting frame 1, the movement trajectory is stable, which can ensure that the extrusion roller 25 extrudes the wire 5 accurately, thereby achieving a precise bending effect.
[0058] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
