Description

Technical Field

[0001] This utility model relates to the field of transformer shearing equipment, and in particular to a shearing tool for transformer production. Background Technology

[0002] After a transformer is manufactured, its pin length is generally the standard length. However, different application scenarios have different requirements for the length of the transformer pins. When using the transformer, it is generally necessary to cut the pins using a pin-cutting jig or equipment.

[0003] The reference patent is titled "A Transformer Lead Cutting Machine" (Patent Publication No.: CN219253966U). It features two blades detachably connected to a U-shaped frame. The blades are fixed to the surface of a rotating blade holder. The two blade holders can rotate in opposite directions when the rack slides, thereby cutting the transformer leads placed on the blade's sliding path. The rack is directly driven by an electric telescopic rod. The overall device occupies relatively little space, and the drive does not require any external auxiliary equipment, making it easy to carry and use outdoors.

[0004] However, the following problems exist when implementing the above technical solutions: After the above device cuts the transformer pins, it is difficult to ensure that the length of all pins is consistent; the transformer pins are generally located on both sides, and the above device only sets blades that move in opposite directions to cut the pins. During the cutting process, the pins on both sides will move closer to the middle of the transformer. The position of the transformer pins is fixed by cutting, but the transformer position mainly relies on manual subjective placement, which makes it difficult to ensure that the transformer is located in the middle of the U-shaped frame. The displacement of the transformer position will cause the pin length on one side to be greater than that on the other side, resulting in different lengths of the transformer pins on both sides after cutting, which does not meet the usage requirements.

[0005] Therefore, this utility model proposes a shearing tool for transformer production. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1 to 5 As shown in the figure, an embodiment of this utility model provides a shearing tool for transformer manufacturing, comprising:

[0029] The equipment box 1 and two shearing frames 2 are slidably disposed inside the equipment box 1 and are symmetrically arranged relative to the equipment box 1. A drive assembly is provided between the two shearing frames 2 and the equipment box 1 to drive the two shearing frames 2 to rotate in opposite directions. Each end of the shearing frame 2 is detachably connected to a blade holder 3, and each surface of the blade holder 3 is detachably connected to a shearing blade 4.

[0030] A placement rack 5 is rotatably mounted inside the equipment box 1; two shearing racks 2 are symmetrically arranged opposite the placement rack 5; two extension rods 6 are rotatably connected inside the placement rack 5; a synchronization component is provided between the two extension rods 6 to drive them to rotate towards each other; each extension rod 6 has a stop rod 7 rotatably connected to its end; extension blocks 8 are detachably connected to the surface of each stop rod 7; a heightening component is provided on the side of the placement rack 5 away from the shearing rack 2 for placing the transformer.

[0031] In summary, the present invention provides a transformer lead shearing fixture, comprising two shearing frames 2 and a placement frame 5 disposed inside an equipment box 1. The two shearing frames 2 are symmetrically arranged relative to the equipment box 1, and the placement frame 5 is disposed in the middle of the equipment box 1. The surface of the placement frame 5 is provided with a heightening component, which is used to place the transformer and thus restrict the position of the transformer. A rotating extension rod 6 is provided on the side of the placement frame 5 near the shearing frame 2, and a rotating abutment rod 7 is provided at the end of the extension rod 6. The two abutment rods 7 rotate towards each other, and the abutment rods 7 contact the leads of the transformer to ensure that the transformer is in the middle position of the equipment box 1. After the two shearing frames 2 are driven to rotate towards each other, the shearing blade 4 contacts the abutment rod 7 and the extension block 8, and can cut the leads of the transformer. The transformer is in the middle position of the equipment box 1, ensuring that the length of the cut transformer leads is the same. When placing the transformer, there is no need to pay attention to the position. The transformer can be adjusted to the middle position of the equipment box 1 by rotating the abutment rod 7, which is convenient to operate.

[0032] In some specific embodiments, the drive assembly includes two rotating rods 9 and two intermediate rods 10 rotatably disposed inside the equipment housing 1. The ends of the rotating rods 9 and the intermediate rods 10 are rotatably connected to the shearing frame 2. The two rotating rods 9 and the intermediate rods 10 are symmetrical relative to the equipment housing 1. An electric push rod 11 is fixedly connected inside the equipment housing 1. The end of the electric push rod 11 is rotatably connected to two drive rods 12. The ends of the drive rods 12 are rotatably connected to the surface of the intermediate rods 10. The electric push rod 11 pulls the end of the drive rod 12 to slide, causing the other end of the drive rod 12 to change position, thereby pulling the other end of the intermediate rod 10 to rotate, causing the rotating rods 9 to rotate, and thus causing the shearing frames 2 to slide towards each other.

[0033] In some specific implementations, the shearing frame 2 has a fixing groove on its surface, and the end of the blade holder 3 is fixedly connected to a fixing shaft 13. The fixing shaft 13 is adapted to the fixing groove, which is a semi-open groove. A contact post 14 is slidably connected inside the fixing groove, and the maximum distance between the contact post 14 and the fixing groove is equal to the length of the fixing shaft 13. By aligning the positions of the fixing shaft 13 and the fixing groove, the blade holder 3 can slide into the shearing frame 2, and the contact post 14 is slidably arranged inside the fixing groove. Both sides of the fixing shaft 13 can simultaneously fit against the inner wall of the fixing groove and the surface of the contact post 14, restricting the position of the fixing shaft 13 and ensuring that the relative positions of the blade holder 3 and the shearing frame 2 remain unchanged.

[0034] In some specific implementations, the synchronization component includes two synchronization wheels 15, both of which are rotatably disposed inside the placement frame 5. A synchronization belt 16 is cross-connected between the two synchronization wheels 15. One synchronization wheel 15 is fixedly connected to the extension rod 6, and the other synchronization wheel 15 is slidably connected to the extension rod 6. A limit component is provided between the sliding synchronization wheel 15 and the placement frame 5 to limit the rotation of the synchronization wheel 15.

[0035] In a further embodiment, the limiting component includes a limiting rod 17 slidably disposed inside the extension rod 6. The limiting rod 17 is slidably connected to the synchronous wheel 15. A limiting gear 18 is fixedly connected to the surface of the limiting rod 17. A limiting groove is formed inside the placement frame 5. The limiting groove is adapted to the limiting rod 17. A fixing tooth 19 is fixedly connected inside the limiting groove. The fixing tooth 19 meshes with the limiting gear 18. The length of the fixing tooth 19 is less than the length of the limiting groove. The limiting gear 18 can slide to contact the fixing tooth 19 and can also slide away from the fixing tooth 19, so that the limiting gear 18 is located alone inside the limiting groove. At this time, the limiting rod 17 can be rotated to drive the synchronous wheel 15 and the extension rod 6 to rotate.

[0036] In some specific implementations, a connecting shaft 20 is fixedly connected to the end of the extension block 8, and a connecting groove is formed on the surface of the abutment rod 7. The connecting shaft 20 is adapted to the connecting groove, and the cross-section of the connecting shaft 20 is T-shaped. A placement groove 21 is formed on the surface of the abutment rod 7. The cross-section of the placement groove 21 is rectangular, and the placement groove 21 is adapted to the connecting shaft 20. At the position of the placement groove 21, the connecting shaft 20 can be inserted into the abutment rod 7. By pulling the extension block 8, the connecting shaft 20 can be slid into the connecting groove, thus restricting the position of the extension block 8 and the abutment rod 7.

[0037] In some specific implementations, the height-increasing component includes a height-increasing block 22 slidably disposed on the surface of the placement frame 5. A height-increasing rod 23 is threadedly connected inside the placement frame 5. An indentation groove (not shown in the figure) is formed on the surface of the height-increasing block 22. The height-increasing rod 23 is adapted to the indentation groove. After rotating the height-increasing rod 23 and inserting it into the indentation groove, rotating the height-increasing rod 23 again can cause the height-increasing block 22 to move upward. After placing the transformer on the surface of the height-increasing block 22, rotating the height-increasing rod 23 can change the position of the transformer.

[0038] In some specific implementations, a magnetic rod 24 is fixedly connected to the surface of the placement rack 5, and two magnetic shafts 25 are fixedly connected to the surface of the equipment box 1. The two magnetic shafts 25 are located on the same horizontal line and are symmetrically arranged relative to the placement rack 5. The magnetic poles of the magnetic rod 24 and the magnetic shafts 25 are opposite. Rotating the placement rack 5 can cause the magnetic rod 24 to disengage from one side of the magnetic shaft 25. The two magnetic shafts 25 limit the rotation angle of the placement rack 5.

[0039] In some specific implementations, the equipment box 1 has a placement slot 21 and a limiting slot inside. A sealing rod is slidably connected inside the placement slot 21. Two limiting shafts are slidably connected inside the sealing rod. A limiting spring is fixedly connected between the two limiting shafts. The limiting shafts are adapted to the limiting slot. A detachable structure such as a shearing blade 4 can be placed through the placement slot 21.

[0040] The working principle of this utility model:

[0041] When it is necessary to cut the transformer pins, first slide the knife holder 3 into the shearing frame 2, place the fixed shaft 13, and then fix the shearing blade 4 into the knife holder 3. Then rotate the placement frame 5 so that one end of the placement frame 5 is detached from the equipment box 1. Then rotate the abutment rod 7 so that the abutment rod 7 is perpendicular to the placement frame 5. Slide the extension block 8 into the abutment rod 7. Then place the transformer on the surface of the heightening block 22. Rotate the heightening rod 23 so that the position where the transformer pin needs to be cut is below the shearing blade 4. Then pull the limit rod 17 so that the limit gear 18 and the fixed gear 19 are disengaged. Rotate the limit rod 17. The rotation of the limit rod 17 drives the synchronous wheel 15 and the extension rod 6 to rotate. At the same time, it causes the extension rod 6 on the other side to rotate in the opposite direction. After the abutment rod 7 and the extension block 8 are in contact with the transformer pins, start the electric push rod 11 so that the drive rod 12 slides into the equipment box 1, drives the central rotating rod 10 to rotate, and causes the shearing blades 4 on both sides to move in the opposite direction to cut the transformer pins.

[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
