Description

Technical Field

[0001] The present invention relates to the field of electric power construction devices, and more particularly to a shaping device for transformer leads. Background Art

[0002] Transformer leads refer to parts of cables led out from the coils of transformers. During actual operations, it is not only necessary to bend the transformer leads according to actual needs; but also in some cases, it is necessary to straighten the bent transformer leads. Currently, the operations of bending and straightening transformer leads generally still adopt manual operation methods. Manual operation for bending or straightening transformer leads is time-consuming and laborious, with low efficiency; especially for bending or straightening transformer leads with a larger diameter, it is even more difficult to operate. Summary of the Invention

[0003] The object of the present invention is to provide a shaping device for transformer leads that can not only bend the transformer leads according to needs, but also straighten the transformer leads according to needs, and has good versatility, and can meet the bending and straightening needs of transformer leads with various different outer diameter models.

[0004] The technical solution of the present invention is as follows:

[0005] A shaping device for transformer leads, comprising:

[0006] A frame;

[0007] A driving device,

[0008] A lead straightening device, the lead straightening device includes a fixed pressure plate and a moving pressure plate that are parallel to each other, wherein the fixed pressure plate is fixed on the frame, and the driving device is used to drive the moving pressure plate to approach or move away from the fixed pressure plate;

[0009] A lead bending device, the lead bending device includes a moving bending member and two blocking wheels arranged on the frame, the moving bending member shares a driving device with the moving pressure plate, the driving device is used to drive the moving bending member to move, and the moving trajectory of the moving bending member is located between the two blocking wheels.

[0010] The shaping device for transformer leads in this solution bends the transformer leads through the moving bending member and the blocking wheels of the lead bending device, and straightens the bent transformer leads through the fixed pressure plate and the moving pressure plate of the lead straightening device, so as to realize the bending and straightening of the transformer leads, and has good versatility, and can meet the bending and straightening requirements of transformer leads with various different outer diameter models. On the other hand, the moving pressure plate of the lead straightening device and the moving bending member of the lead bending device share a driving device, which realizes the omission of a driving device without affecting the normal operation of the lead straightening device and the lead bending device, simplifies the device structure, and reduces the device cost.

[0011] Preferably, the driving device includes a first guide rod fixed to the frame, a driving screw rod rotatably provided on the frame, two driving nuts engaged with the driving screw rod, and a driving motor for driving the driving screw rod to rotate. The first guide rod is parallel to the driving screw rod. Guide sleeves engaged with the first guide rod are provided on both the moving pressure plate and the moving press-bending member. One of the two driving nuts is fixed to the moving pressure plate, and the other driving nut is fixed to the moving press-bending member. In this way, the moving stability of the moving press-bending member and the moving pressure plate is ensured, and it is ensured that only one driving device is used to drive the moving pressure plate of the lead straightening device and the moving press-bending member of the lead bending device without affecting the normal operation of the lead straightening device and the lead bending device.

[0012] Preferably, the fixed pressure plate, the moving pressure plate, and the moving press-bending member are sequentially distributed along the axial direction of the driving screw rod, and the driving screw rod is located between the axes of the two blocking wheels.

[0013] Preferably, a lead bending angle adjusting device is further included. The lead bending angle adjusting device includes a second guide rod fixed to the frame, two sliding sleeves sliding along the second guide rod, vertical mounting rods provided corresponding to the sliding sleeves one by one, and a position adjusting mechanism for adjusting the distance between the two sliding sleeves. The moving track of the moving press-bending member is perpendicular to the second guide rod. The blocking wheels correspond to the vertical mounting rods one by one, and the blocking wheels are mounted on the corresponding vertical mounting rods. Since the moving press-bending member and the moving pressure plate share a driving device, and the moving strokes of both the moving pressure plate and the moving press-bending member are limited by the fixed pressure plate, it is difficult to realize transformer leads with different bending angles by adjusting the stroke of the moving press-bending member. Therefore, the lead bending angle adjusting device is provided in this solution. By adjusting the positions of the two sliding sleeves, the distance between the two blocking wheels is adjusted, so as to change the bending angle of the lead without changing the moving stroke of the moving press-bending member.

[0014] Preferably, a blocking wheel locking device is further included. The frame includes an operating table board. Strip-shaped openings corresponding to the vertical mounting rods one by one are provided on the operating table board. The length direction of the strip-shaped openings is parallel to the second guide rod. The vertical mounting rods pass through the corresponding strip-shaped openings. The blocking wheels are located above the operating table board. The blocking wheel includes a locking sleeve sleeved on the corresponding vertical mounting rod and an outer wheel sleeve sleeved outside the locking sleeve. The locking sleeve is located above the operating table board.

[0015] The blocking wheel locking device corresponds to the vertical mounting rods one by one. The blocking wheel locking device includes an external thread provided on the upper part of the corresponding vertical mounting rod and a locking nut engaged with the external thread on the upper part of the vertical mounting rod. The locking nut is located above the locking sleeve and is used to lock and fix the locking sleeve on the upper surface of the operating table board.

[0016] During the process of bending the leads of the transformer, in order to avoid the force acting on the blocking wheel and being transmitted through the vertical mounting rod to the position adjustment mechanism, which may cause damage to the position adjustment mechanism and affect its normal operation, this solution specifically sets up a specific blocking wheel structure and a blocking wheel locking device. Specifically, when it is necessary to adjust the spacing between the blocking wheels, loosen the locking nut, and then adjust the spacing between the two blocking wheels through the position adjustment mechanism. After the spacing between the two blocking wheels is adjusted, lock the locking nut to lock and fix the locking sleeve on the upper surface of the operating table board, thereby locking and fixing the blocking wheels on the operating table board. In this way, during the process of bending the transformer leads, the force acting on the blocking wheels will act on the operating table board and will not act on the position adjustment mechanism.

[0017] Preferably, it further includes a missed-lock blocking mechanism. The missed-lock blocking mechanisms correspond to the blocking wheels one by one. The missed-lock blocking mechanism includes a compression spring, an annular pressing plate arranged at the lower edge of the locking sleeve of the corresponding blocking wheel, a blocking plate opening arranged on the operating table board, a vertical blocking lifting plate located in the blocking plate opening, and a blocking member arranged on the dynamic bending member for cooperating with the vertical blocking lifting plate. The vertical blocking lifting plate is located below the annular pressing plate, and the vertical blocking lifting plate is pushed upward by the compression spring and abuts against the lower surface of the annular pressing plate. The blocking member is located above the operating table board and is close to the upper surface of the operating table board. When the annular pressing plate abuts against the upper surface of the operating table board, the upper end surface of the vertical blocking lifting plate is flush with the upper surface of the operating table board.

[0018] The lead bending device is used to bend the leads of the transformer. When bending the leads of the transformer, first place the transformer leads to be bent on the operating table board, so that the two blocking wheels are on the same side of the transformer leads, and the dynamic bending member and the blocking wheels are on the opposite sides of the transformer leads. At this time, the vertical blocking lifting plate and the transformer leads are on the same side of the blocking member. Then, the driving device drives the dynamic bending member to move towards the transformer leads. At this time, if the locking nut locks and fixes the locking sleeve on the upper surface of the operating table board, when the annular pressing plate abuts against the upper surface of the operating table board, the upper end surface of the vertical blocking lifting plate is flush with the upper surface of the operating table board, then the driving device can drive the dynamic bending member to abut against the transformer leads and bend the transformer leads.

[0019] If a certain locking nut does not lock and fix the locking sleeve on the upper surface of the operating table board, the compression spring will push up the vertical blocking lifting plate and the corresponding blocking wheel, so that the upper end surface of the vertical blocking lifting plate is above the upper surface of the operating table board. When the position of the upper end surface of the vertical blocking lifting plate is higher than the lowest position of the blocking member, during the process of the driving device driving the dynamic bending member to move towards the transformer leads, the dynamic bending member and the blocking member will be blocked by the vertical blocking lifting plate to prevent the dynamic bending member from abutting against the transformer leads.

[0020] Although a blocking wheel locking device is provided on the plastic shaping device for transformer leads, as long as the operator can operate according to the regulations, the force acting on the blocking wheel can be avoided, and the problem of the position adjustment mechanism being damaged due to the force acting on the position adjustment mechanism through the vertical mounting rod can be avoided; however, in the actual operation process, there will still be some situations where after the distance between the two blocking wheels is adjusted, due to unfamiliar operation or carelessness, the operator forgets to lock the locking nut, resulting in the failure of the blocking wheel locking device, and the force acting on the blocking wheel acts on the position adjustment mechanism through the vertical mounting rod. To solve this problem, this solution provides a missed locking blocking mechanism. Specifically, in the actual operation process, if the operator operates according to the regulations and locks the locking sleeve to the upper surface of the operating table board through the locking nut after the distance between the two blocking wheels is adjusted, the annular pressing plate will abut against the upper surface of the operating table board. Thereafter, the driving device can drive the moving pressing member to abut against the transformer lead and bend the transformer lead; if the operator does not lock the locking nut after the distance between the two blocking wheels is adjusted, the compression spring will lift the vertical blocking lifting plate and the corresponding blocking wheel, so that the upper end surface of the vertical blocking lifting plate is located above the upper surface of the operating table board. When the position where the upper end surface of the vertical blocking lifting plate is located is higher than the lowest position of the blocking member, during the process of the driving device driving the moving pressing member to move towards the transformer lead, the moving pressing member and the blocking member will be blocked by the vertical blocking lifting plate to prevent the moving pressing member from abutting against the transformer lead, thereby reminding the operator that the locking nut is not locked and forcing the operator to operate again according to the regulations.

[0021] Preferably, the moving adjustment mechanism includes an adjustment screw rotatably provided on the frame and two adjustment nuts corresponding to the sliding sleeves one by one. The adjustment screw is parallel to the second guide rod. The threads on the adjustment screw include a forward thread section and a reverse thread section with opposite spiral directions. One of the two adjustment nuts is engaged with the forward thread section, and the other adjustment nut is engaged with the reverse thread section. The adjustment nut is fixedly connected to the corresponding sliding sleeve. In this way, the distance between the two blocking wheels can be adjusted by rotating the adjustment screw.

[0022] Preferably, a driving handwheel is provided at one end of the adjustment screw.

[0023] Preferably, a plastic pressing plate is provided on the side of the fixed pressing plate facing the moving pressing plate, and a plastic pressing plate is also provided on the side of the moving pressing plate facing the fixed pressing plate. In this way, when the moving pressing member and the blocking wheel of the lead bending device bend the transformer lead, they will contact the transformer lead through the plastic pressing plate, which is beneficial to protecting the transformer lead and avoiding scratching the transformer lead.

[0024] Preferably, a plastic pressing plate is also provided on the side surface of the moving pressing member.

[0025] Preferably, walking rollers are provided at the bottom of the frame. In this way, the shaping device for transformer leads can be conveniently pushed by the walking rollers.

[0026] The beneficial effects of the present invention are as follows: It can not only bend the transformer leads as required, but also straighten the transformer leads as required, and has good versatility, capable of meeting transformer leads of various different outer diameter models.

[0037] Detailed Embodiment 1: As Figure 1 , Figure 2 shown, a shaping device for transformer leads includes a frame, a driving device 2, a lead straightening device 3 and a lead bending device 4.

[0038] The lead straightening device 3 includes a fixed pressing plate 3.1 and a moving pressing plate 3.2 that are parallel to each other, where the fixed pressing plate is fixed to the machine frame. The driving device is used to drive the moving pressing plate to approach or move away from the fixed pressing plate. In this way, when it is necessary to straighten the bent transformer lead, the transformer lead to be straightened is placed on the machine frame between the fixed pressing plate and the moving pressing plate. Then, the driving device drives the moving pressing plate to approach the fixed pressing plate, so as to straighten the bent transformer lead through the fixed pressing plate and the moving pressing plate, thereby achieving the straightening of the bent transformer lead.

[0039] The lead bending device 4 includes a moving bending member 4.2 and two blocking wheels 4.1 arranged on the machine frame. The moving bending member and the moving pressing plate share a driving device. The driving device is used to drive the moving bending member to move, and the moving track of the moving bending member is located between the two blocking wheels. When it is necessary to bend the transformer lead, the transformer lead to be bent is placed on the machine frame between the blocking wheels and the moving bending member, so that the two blocking wheels are located on the same side of the transformer lead, and the moving bending member and the blocking wheels are located on the opposite sides of the transformer lead. Then, the driving device drives the moving bending member to move towards the transformer lead, so that the moving bending member abuts against the transformer lead and bends the transformer lead.

[0040] The shaping device for the transformer lead in this embodiment bends the transformer lead through the moving bending member and the blocking wheels of the lead bending device, and straightens the bent transformer lead through the fixed pressing plate and the moving pressing plate of the lead straightening device, so as to achieve the bending and straightening of the transformer lead, and has good versatility, and can meet the requirements of bending and straightening transformer leads of various different outer diameter models. On the other hand, the moving pressing plate of the lead straightening device and the moving bending member of the lead bending device share a driving device, which realizes the omission of a driving device without affecting the normal operation of the lead straightening device and the lead bending device, simplifies the device structure, and reduces the device cost.

[0041] Specifically, the machine frame includes an operating table board 1.1, and a longitudinal through opening 1.1 is provided on the operating table board. The upper surface of the operating table board is horizontally distributed. The driving device 2 includes a first guide rod 2.3 fixed to the machine frame, a driving screw rod 2.1 rotatably arranged on the machine frame, two driving nuts engaged with the driving screw rod, and a driving motor 2.2 for driving the driving screw rod to rotate. The length direction of the longitudinal through opening is parallel to the first guide rod. The first guide rod is parallel to the driving screw rod. Guide sleeves engaged with the first guide rod are provided on both the moving pressing plate and the moving bending member. The moving track of the moving bending member is parallel to the first guide rod. One of the two driving nuts is fixed to the moving pressing plate, and the other driving nut is fixed to the moving bending member. The fixed pressing plate, the moving pressing plate, and the moving bending member are sequentially distributed along the axial direction of the driving screw rod, and the driving screw rod is located between the axes of the two blocking wheels.

[0042] In this embodiment, the first guide rod, the driving screw rod, the guide sleeve and the driving nut are all located below the operating table board. The axis of the blocking wheel is vertically distributed, and the two blocking wheels are located above the operating table board. The dynamic pressing and bending part is vertically distributed. The dynamic pressing and bending part passes through the longitudinal through opening. A part of the dynamic pressing and bending part is located below the operating table board, and the other part of the dynamic pressing and bending part is located above the operating table board. The fixed pressing plate is fixed on the upper surface of the operating table board and is vertically distributed. The movable pressing plate includes a driving member 3.21 and a pressing straight plate 3.22 connected to the driving member. The pressing straight plate is parallel to the fixed pressing plate. The pressing straight plate is located above the operating table board. The driving nut and the guide sleeve on the movable pressing plate are both distributed on the driving member.

[0043] Further, as Figure 1 shown, a plastic pressing plate 3.3 is provided on one side of the fixed pressing plate facing the movable pressing plate, and a plastic pressing plate is also provided on one side of the movable pressing plate facing the fixed pressing plate. In this way, when the dynamic pressing and bending part and the blocking wheel of the lead bending device bend the transformer lead, it will contact the transformer lead through the plastic pressing plate, which is beneficial to protecting the transformer lead and avoiding abrasion of the transformer lead.

[0044] A plastic pressing plate is also provided on the side surface of the dynamic pressing and bending part. Specifically, a plastic pressing plate is also provided on the side surface of the dynamic pressing and bending part facing the movable pressing plate, and the side surface of the plastic pressing plate facing the movable pressing plate is an arc surface.

[0045] Further, as Figure 1 shown, four walking rollers 1.3 are provided at the bottom of the frame. In this way, the plastic shaping device for transformer leads can be conveniently pushed through the walking rollers.

[0046] Specific embodiment two, the rest of the structure of this embodiment refers to specific embodiment one, and the difference is that

[0047] As Figure 1 , Figure 2 shown, the plastic shaping device for transformer leads further includes a lead bending angle adjusting device 5. The lead bending angle adjusting device includes a second guide rod 5.2 fixed on the frame, two sliding sleeves 5.3 sliding along the second guide rod, vertical mounting rods 5.1 provided corresponding to the sliding sleeves one by one, and a position adjusting mechanism for adjusting the distance between the two sliding sleeves. The second guide rod is horizontally distributed. The second guide rod is perpendicular to the first guide rod. The moving track of the dynamic pressing and bending part is perpendicular to the second guide rod. The operating table board is provided with strip-shaped through openings 1.2 corresponding to the vertical mounting rods one by one. The length direction of the strip-shaped through openings is parallel to the second guide rod. The vertical mounting rods pass through the corresponding strip-shaped through openings. The blocking wheels correspond to the vertical mounting rods one by one. The blocking wheels are mounted on the corresponding vertical mounting rods.

[0048] In this embodiment, the moving adjustment mechanism includes an adjustment screw rod 5.4 rotatably arranged on the frame and two adjustment nuts 5.5 corresponding to the sliding sleeves one by one. The adjustment screw rod is parallel to the second guide rod. The thread on the adjustment screw rod includes a forward thread section and a reverse thread section with opposite spiral directions. One of the two adjustment nuts is engaged with the forward thread section, and the other adjustment nut is engaged with the reverse thread section. The adjustment nut is fixedly connected to the corresponding sliding sleeve. One end of the adjustment screw rod is provided with a driving handwheel. In this way, the driving handwheel can be used to drive the adjustment screw rod to rotate, thereby adjusting the distance between the two blocking wheels. In this embodiment, both the adjustment screw rod and the second guide rod are located below the operation table board.

[0049] Since the dynamic pressure bending part and the dynamic pressure plate share a driving device, the moving strokes of the dynamic pressure plate and the dynamic pressure bending part are both limited by the fixed pressure plate, making it difficult for transformer leads with different bending angles to be achieved by adjusting the stroke of the dynamic pressure bending part. Therefore, this solution provides a lead bending angle adjustment device, which adjusts the distance between the two blocking wheels by adjusting the positions of the two sliding sleeves, so as to change the bending angle of the lead without changing the moving stroke of the dynamic pressure bending part.

[0050] Specific Embodiment 3, the rest of the structure of this embodiment refers to Specific Embodiment 2, and the difference lies in that

[0051] As Figure 1 , Figure 2 shown, the shaping device for transformer leads further includes a blocking wheel locking device 6. The blocking wheel 4.1 includes a locking sleeve 4.11 sleeved on the corresponding vertical mounting rod and an outer wheel sleeve 4.12 sleeved outside the locking sleeve. The locking sleeve is located above the operation table board, and the outer wheel sleeve can rotate relative to the locking sleeve. The blocking wheel locking device corresponds to the vertical mounting rod one by one. The blocking wheel locking device 6 includes an external thread 6.2 provided on the upper part of the corresponding vertical mounting rod and a locking nut 6.1 engaged with the external thread on the upper part of the vertical mounting rod. The locking nut is located above the locking sleeve and is used to lock and fix the locking sleeve on the upper surface of the operation table board.

[0052] During the process of bending the transformer lead, in order to prevent the force exerted on the blocking wheel from acting on the position adjustment mechanism through the vertical mounting rod, resulting in damage to the position adjustment mechanism and affecting the normal operation of the position adjustment mechanism, this solution specifically provides a specific blocking wheel structure and a blocking wheel locking device. Specifically, when it is necessary to adjust the distance between the two blocking wheels, the locking nut is loosened, and then the distance between the two blocking wheels is adjusted through the position adjustment mechanism; after the distance between the two blocking wheels is adjusted, the locking nut is tightened to lock and fix the locking sleeve on the upper surface of the operation table board, thereby locking and fixing the blocking wheel on the operation table board. In this way, during the process of bending the transformer lead, the force exerted on the blocking wheel will act on the operation table board and will not act on the position adjustment mechanism.

[0053] Specific Embodiment 4. The remaining structure of this embodiment refers to Specific Embodiment 3, and the difference lies in that

[0054] As Figure 1 , Figure 2 shown, the plastic shaping device for transformer leads further includes a missing-lock blocking mechanism 7. The missing-lock blocking mechanisms correspond to the blocking wheels one by one. The missing-lock blocking mechanism includes a compression spring, an annular pressing plate 7.3 provided at the lower edge of the locking sleeve of the corresponding blocking wheel, a blocking plate opening provided on the operating table board, a vertical blocking lifting plate 7.1 located in the blocking plate opening, and a blocking member 7.2 provided on the dynamic pressing and bending member for cooperating with the vertical blocking lifting plate. The vertical blocking lifting plate can move up and down in the vertical direction. The vertical blocking lifting plate is located below the annular pressing plate, and the vertical blocking lifting plate is pushed up by the compression spring and abuts against the lower surface of the annular pressing plate. The blocking member is located above the operating table board, and the blocking member is close to the upper surface of the operating table board; in this embodiment, the blocking member is a blocking block, and the gap between the lower surface of the blocking member and the upper surface of the operating table board close to it is 0.1 - 0.3 mm. When the annular pressing plate abuts against the upper surface of the operating table board, the upper end surface of the vertical blocking lifting plate is flush with the upper surface of the operating table board.

[0055] Specifically, the missing-lock blocking mechanism further includes a vertical guide sleeve provided on the frame and a lifting rod that lifts along the vertical guide sleeve. The vertical blocking lifting plate is fixed to the upper end of the lifting rod, the compression spring is sleeved on the lifting rod, the lower end of the compression spring abuts against the upper end of the vertical guide sleeve, and the upper end of the compression spring abuts against the lower end of the vertical blocking lifting plate.

[0056] The vertical blocking lifting plate 7.1 includes a vertical lifting plate 7.11 parallel to the second guide rod and a vertical blocking plate 7.12 perpendicular to the vertical lifting plate. The vertical lifting plate and the vertical blocking plate are integrally connected, and the upper end surfaces of the vertical lifting plate and the vertical blocking plate are flush. The vertical lifting plate is located below the corresponding annular pressing plate and abuts against the lower surface of the annular pressing plate. The vertical blocking plate and the dynamic pressing plate are located on both sides of the vertical lifting plate.

[0057] When bending the transformer leads, first place the transformer leads to be bent on the operating table board, so that the two blocking wheels are on the same side of the transformer leads, and the dynamic pressing and bending member and the blocking wheels are on opposite sides of the transformer leads. At this time, the vertical blocking lifting plate and the transformer leads are on the same side of the blocking member; then, the driving device drives the dynamic pressing and bending member to move towards the transformer leads. At this time, if the locking nut locks and fixes the locking sleeve on the upper surface of the operating table board, when the annular pressing plate abuts against the upper surface of the operating table board, the upper end surface of the vertical blocking lifting plate is flush with the upper surface of the operating table board, then the driving device can drive the dynamic pressing and bending member to abut against the transformer leads and bend the transformer leads;

[0058] If a locking nut fails to lock and fix the locking sleeve on the upper surface of the operating table board, the compression spring will push up the vertical blocking lifting plate and the corresponding blocking wheel, so that the upper end surface of the vertical blocking lifting plate is located above the upper surface of the operating table board. When the position of the upper end surface of the vertical blocking lifting plate is higher than the lowest position of the blocking member (that is, when the position of the upper end surface of the vertical blocking lifting plate is higher than the lower surface of the blocking member), during the process of the driving device driving the dynamic press-bending member to move towards the transformer lead, the dynamic press-bending member and the blocking member will be blocked by the vertical blocking lifting plate to prevent the dynamic press-bending member from abutting against the transformer lead.

[0059] Although a blocking wheel locking device is provided on the plastic shaping device for the transformer lead, as long as the operator can operate according to the regulations, the problem that the force received by the blocking wheel acts on the position adjusting mechanism through the vertically installed rod and causes damage to the position adjusting mechanism can be avoided. However, in the actual operation process, there will still be some situations where after the distance between the two blocking wheels is adjusted, due to unfamiliar operation or carelessness, the operator forgets to lock the locking nut, resulting in the failure of the blocking wheel locking device, and the problem that the force received by the blocking wheel acts on the position adjusting mechanism through the vertically installed rod. To solve this problem, this solution provides a missed-locking blocking mechanism. Specifically, in the actual operation process, if the operator operates according to the regulations and locks and fixes the locking sleeve on the upper surface of the operating table board with the locking nut after the distance between the two blocking wheels is adjusted, the annular pressing plate abuts against the upper surface of the operating table board. After that, the driving device can drive the dynamic press-bending member to abut against the transformer lead and bend the transformer lead. If the operator does not lock the locking nut after the distance between the two blocking wheels is adjusted, the compression spring will push up the vertical blocking lifting plate and the corresponding blocking wheel, so that the upper end surface of the vertical blocking lifting plate is located above the upper surface of the operating table board. When the position of the upper end surface of the vertical blocking lifting plate is higher than the lowest position of the blocking member, during the process of the driving device driving the dynamic press-bending member to move towards the transformer lead, the dynamic press-bending member and the blocking member will be blocked by the vertical blocking lifting plate to prevent the dynamic press-bending member from abutting against the transformer lead, thereby reminding the operator that the locking nut is not locked and forcing the operator to operate again according to the regulations.

[0060] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention. Any simple modification, change, and equivalent transformation made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
