Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, specifically relating to a bending device for a vertical winding machine. Background Technology

[0002] Currently, vertical winding machines use conductors with large cross-sections, making bending difficult. The main bending method currently used is manual bending, which has a low degree of automation and low production efficiency. The main problem is that it is difficult to control the bending length during the manual bending process using a hydraulic bending machine, resulting in inconsistent conductor lengths in each layer of the transformer, ultimately leading to transformer quality issues.

[0003] CN115591979A discloses a bending device, comprising: a conveying mechanism for placing and conveying workpieces to a bending mechanism below it; and a bending mechanism including a bending plate and a rotating motor connected to the bending plate. One side of the bending plate is bent upward to form an arc-shaped pressing part. The rotating motor drives the pressing part to rotate around the rotating shaft of the motor as the center line of rotation. The downward rotating pressing part compresses the workpiece, causing it to form a bent structure. This bending device replaces manual bending operations. The arc-shaped pressing part in the bending mechanism compresses the workpiece through rotation, forming a bent structure, significantly reducing labor intensity and increasing productivity. Furthermore, the bending path of the pressing part is consistent, ensuring that the final bent structure shape and bending angle of each workpiece are uniform, eliminating bending angle deviations and greatly improving the workpiece qualification rate.

[0004] However, it is not suitable for vertical winding machines and cannot achieve reverse or same-direction bending of two conductors. Utility Model Content

[0005] To overcome the problem of difficulty in controlling the bending length during manual hydraulic bending, which leads to inconsistent conductor lengths in each layer of the transformer and ultimately results in poor transformer quality and the inability to achieve reverse or unidirectional bending of double conductors, this invention provides a bending device for a vertical winding machine. This invention features two identical bending systems symmetrically positioned on both sides of the middle plate. The two bending systems enable reverse or unidirectional bending of double conductors. After the conductor passes through the bending device, a length measuring device measures the conductor. Once the predetermined length is reached, the bending distance is adjusted according to the bending length, and the conductor is clamped by left and right clamping devices before bending. This bending device offers advantages such as high distance measurement accuracy, precise bending angle, and adjustable bending length, realizing the conductor bending function of a vertical winding machine and is suitable for conductor bending in the electrical engineering field.

[0006] The technical solution adopted in this utility model is as follows:

Figures 1-6 This invention discloses a bending device for a vertical winding machine. The device comprises two identical bending systems symmetrically positioned on both sides of a central plate. The two bending systems enable reverse and unidirectional bending of two conductors. After the conductor passes through the bending device, a length measuring device measures the conductor.

This bending device offers advantages such as high distance measurement accuracy, precise bending angle, and adjustable bending length, thus realizing the conductor bending function of a vertical winding machine and is suitable for conductor bending in the electrical engineering field.

[0033] A bending device for a vertical winding machine includes a base 1, a middle plate 31, a length measuring device 12, and a bending system. The middle plate 31 is located inside the base 1, and two ends of the middle plate 31 are respectively connected to a first slewing bearing 3 and a second slewing bearing 15. Both the first slewing bearing 3 and the second slewing bearing 15 are connected to the inner wall of the base 1. A first reduction motor 16 is located on the outer wall of the base 1 where the second slewing bearing 15 is located. The first reduction motor 16 is connected to the second slewing bearing 15 through a gear 18. There are two sets of bending systems with the same structure. The two sets of bending systems are symmetrically arranged on both sides of the middle plate 31. The position of the base 1 is adjusted by a distance adjustment device. The length measuring device 12 is located inside the base 1.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model includes two bending systems with identical structures, symmetrically positioned on both sides of the middle plate 31. The use of two bending systems enables reverse and unidirectional bending of the two conductors.

This bending device has the advantages of high distance measurement accuracy, precise bending angle, and adjustable bending length. It realizes the function of bending the wire of the vertical winding machine and is suitable for bending wires in the electrical field.

[0038] Example 2:

[0039] Based on Embodiment 1, in this embodiment, preferably, the length measuring device 12 includes cylinder 5, cylinder 10, cylinder 3, cylinder 4, and a length measuring encoder. Cylinder 5, cylinder 2, and cylinder 4 are arranged side by side in the base 1. Cylinder 5, cylinder 2, and cylinder 4 press the wire tightly onto the middle plate 31. When the wire moves, it drives the length measuring encoder located on cylinder 3 to rotate. Cylinder 3 is located at the right bending device 14.

[0041] The length measuring device 12 presses the wire onto the middle plate 31 to prevent the wire from moving by means of cylinder 5, cylinder 10 and cylinder 17. When the wire moves, it drives the length measuring encoder located on cylinder 13 to rotate.

[0043] Preferably, the left bending mechanism includes a left bending device 6 and a left clamping device 29. The left clamping device 29 includes an electric cylinder 28, a left moving pressure plate 8, and a linear guide rail 27. The left moving pressure plate 8 moves on the linear guide rail 27 via the electric cylinder 28. The linear guide rail 27 is vertically mounted on the left bending device 6. A left fixed pressure plate 7 is connected to the upper end of the left bending device 6. Figure 4 As shown.

[0044] Preferably, the right bending mechanism includes a right clamping device 33 and a right bending device 14. The right clamping device 33 includes a right movable pressure plate 19, an electric cylinder 22, and a linear guide rail 21. The electric cylinder 22 drives the right movable pressure plate 19 to move on the linear guide rail 21. The linear guide rail 21 is vertically distributed on the right bending device 14. The upper end of the right bending device 14 is provided with a right fixed pressure plate 11. The cylinders 10 and 17 of the length measuring device 12 are respectively located on both sides of the right bending device 14. The right bending device 14 is connected to the side plate 34 through the linear guide rail 32, and the right bending device 14 is driven to move on the linear guide rail 32 by the electric cylinder 24.

[0045] like Figure 1 , Figure 5 and Figure 6 As shown, in this invention, the left moving pressure plate 8 moves upward under the action of electric cylinder 28, clamping the wire with the left fixed pressure plate 7. The right clamping device 33 mainly controls the right moving pressure plate 19 to move upward through electric cylinder 22, clamping the wire with the right fixed pressure plate 11. After the right clamping device 33 clamps the wire, the right bending device 14 moves up and down through electric cylinder 24 to achieve bending. The right bending device 14 includes at least a bending plate and electric cylinder 24, and the bending plate moves up and down on the side plate 34 through a corresponding linear guide rail.

[0047] Preferably, the slewing bearing 3 is fixed to the base 1 by the slewing bearing connecting plate 2.

[0048] In this utility model, the slewing bearing 3 is fixed to the base 1 by the slewing bearing connecting plate 2, and the geared motor 16 drives the slewing bearing 15 through the gear 18 to realize the rotation of the bending device.

[0049] Preferably, the distance adjustment device includes a second motor 23, a lead screw 20, and a fifth linear guide rail 30. The base 1 is located on the fifth linear guide rail 30. One end of the lead screw 20 is connected to the second motor 23, and the other end is connected to the base 1.

[0050] In this invention, the bending distance is fine-tuned by a distance adjustment device. The fine-tuning of the bending distance is accomplished by motor 23, lead screw 20, and linear guide rail 30. If the bending distance is less than the theoretical distance, motor 23 controls lead screw 20 to rotate, and the entire device moves to the right relative to the ground, increasing the bending distance. If the bending distance is greater than the theoretical distance, motor 23 controls lead screw 20 to rotate, and the entire device moves to the left relative to the ground, decreasing the bending distance.

[0051] In this invention, a geared motor 16 drives a slewing bearing 15 via a gear 18, thereby changing the two states of the bending device, including a horizontal state and a vertical state.

[0052] The following bending process can be achieved using the structure provided by this utility model:

[0053] 1. The specific process of bending vertically upwards is as follows:

[0054] Powered by a geared motor 16, the slewing bearing 15 is driven by gear 18 to place the entire bending device in a vertical position. The length measuring device 12 is activated and, through cylinders 5, 10, 13, and 17, presses the wire onto the middle plate 31. The vertical winding machine begins to work, the wire moves relative to itself, and the length measuring encoder records the length of the wire movement.

[0055] Once the set bending length is reached, the length measuring device 12 stops working. According to the set bending length, the bending length adjusting device 26 is connected to the middle plate 31 through the corresponding linear guide rail and moves left and right by the electric cylinder 4 until the predetermined bending length is reached.

[0056] Electric cylinder 4 28 controls the left movable pressure plate 8 to move upward, clamping the left end of the wire with the left fixed pressure plate 7. Electric cylinder 2 22 controls the right movable pressure plate 19 to move upward, clamping the right end of the wire with the right fixed pressure plate 11.

[0058] II. The specific process of bending vertically downwards is as follows:

[0059] Powered by a geared motor 16, the slewing bearing 15 is driven by gear 18 to place the entire bending device in a vertical position. The length measuring device 12 is activated and, through cylinders 5, 10, 13, and 17, presses the wire onto the middle plate 31. The vertical winding machine begins to work, the wire moves relative to itself, and the length measuring encoder records the length of the wire movement.

[0060] Once the set bending length is reached, the length measuring device 12 stops working. According to the set bending length, the bending length adjusting device 26 is connected to the side plate 34 through a linear guide rail and is controlled to move left and right by the electric cylinder 4 until the predetermined bending length is reached.

[0061] Electric cylinder 4 28 controls the left movable pressure plate 8 to move upward, clamping the left end of the wire with the left fixed pressure plate 7. Electric cylinder 2 22 controls the right movable pressure plate 19 to move upward, clamping the right end of the wire with the right fixed pressure plate 11. The right bending device 14 is moved downward by electric cylinder 3 24 to achieve downward bending.

[0062] Record the bend position.

[0063] III. Horizontal bending, the specific process is as follows:

[0064] Powered by a geared motor 16, the slewing bearing 15 is driven by gear 18 to place the entire bending device in a horizontal position. The length measuring device 12 is activated and, through cylinders 5, 10, 13, and 17, presses the wire onto the middle plate 31. The vertical winding machine begins to work, the wire moves relative to itself, and the length measuring encoder records the length of the wire movement.

[0065] Once the set bending length is reached, the length measuring device 12 stops working. According to the set bending length, the bending length adjusting device 26 is connected to the middle plate 31 through the corresponding linear guide rail and moves left and right by the electric cylinder 4 until the predetermined bending length is reached.

[0066] Electric cylinder 4 28 controls the left movable pressure plate 8 to move upward, clamping the left end of the wire with the left fixed pressure plate 7. Electric cylinder 2 22 controls the right movable pressure plate 19 to move upward, clamping the right end of the wire with the right fixed pressure plate 11. The right bending device 14 is moved downward by electric cylinder 3 24 to achieve downward bending.

[0067] Record the bend position.

[0068] This invention can adjust the bending position. Based on the bending position recorded in the above three bending situations, when making the next bend, the movement of the entire device can be controlled by the motor 23 controlling the lead screw 20 according to the bending length, thereby accurately controlling the bending distance and greatly improving the accuracy of the distance between bends.

[0069] This utility model has two bending systems in the base 1. The two bending systems are symmetrically distributed along the center line and are located on both sides of the middle plate 31. According to the specific bending requirements, the two conductors can be bent in the same direction or in opposite directions.

[0070] In this invention, after the wire passes through the bending device, the length measuring device 12 measures the wire. Once the predetermined length is reached, the bending distance is adjusted according to the bending length. After clamping with left and right clamping devices, the wire is bent. This bending device has the advantages of high distance measurement accuracy, precise bending angle, and adjustable bending length. It realizes the function of bending the wire of the vertical winding machine and is suitable for bending wires in the electrical field.
