Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of transformers, in particular to a transformer skeleton pin cutting machine device. Background Art
[0002] With the rapid development of the electronics manufacturing industry, demand for transformers, as key components, is increasing. Precisely cutting the pins on the transformer bobbin is a crucial step in ensuring performance and quality during transformer production. However, traditional manual or semi-automatic pin cutting methods are inefficient and labor-intensive, and they also struggle to ensure consistent and precise cuts. To overcome these challenges, a variety of automated pin cutting machines have emerged on the market. While existing automated pin cutting machines have improved efficiency and precision to a certain extent, they still have some shortcomings in practical applications.
[0003] The transformer bobbin is one of the core components in transformer manufacturing. After winding, its pins often need to be precisely cut according to actual assembly requirements. To improve production efficiency and processing accuracy, needle cutting equipment has gradually replaced traditional manual shearing methods. However, many problems still exist in actual applications. For example, most existing needle cutting machines do not have a dedicated pin positioning structure, relying on the operator's experience for placement, which can easily lead to inconsistent pin lengths. If the pin insertion position deviates, the cutter will not be able to accurately align with the pin, resulting in uneven cuts and inaccurate dimensions at best, and even damage to the transformer bobbin at worst. The needle length can be flexibly changed according to requirements by replacing the needle length fixing plate to accommodate any needle length requirement. Summary of the Invention

[0033] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.
[0034] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.
[0035] This embodiment provides Figures 1 to 4 The transformer skeleton pin cutting machine device shown is characterized in that it includes a mounting base 1, a power source component 2, a needle length plate fixing seat 5, a sharp main cutting knife 13 and a needle length fixing plate 7.
[0036] In this embodiment, the mounting base 1 is mounted on a workshop workbench. By fixing the mounting base 1 to the workshop workbench, the entire needle cutting device has a stable mounting base, avoiding uneven cuts or processing errors caused by equipment shaking during the needle cutting process, achieving stable operation of the entire device, and achieving the effect of improving processing accuracy and production safety. The power source component 2 is mounted on the top surface of one end of the mounting base 1; the needle long plate fixing seat 5 is mounted on the top surface of the other end of the mounting base 1, and the power execution end of the power source component 2 moves back and forth linearly in the needle long plate fixing seat 5. The needle long plate fixing seat 5 is set at the other end of the mounting base 1 and cooperates with the power source component 2 to form a symmetrical layout. The design makes the entire device compact and rationally laid out, not only saving space, but also facilitating equipment maintenance and tool replacement, achieving optimal equipment space utilization, and achieving the effect of facilitating integration into an automated production line. The sharp main cutter 13 is slidably mounted in the needle long plate fixing seat 5, and the power execution end of the power source component 2 drives the sharp main cutter 13 to slide back and forth linearly in the needle long plate fixing seat 5.
[0037] In this embodiment, the needle length fixing plate 7 is detachably mounted on the top surface of the needle length plate fixing seat 5 and is located directly above the sharp main cutter 13; a needle length plate positioning hole 9 for inserting the pins of the transformer frame is provided at one end of the top surface of the needle length fixing plate 7. After the pins of the transformer frame are inserted into the needle length plate positioning hole 9, the sharp main cutter 13 slides back and forth in a straight line in the needle length plate fixing seat 5 to cut off the pins of the transformer frame.
[0038] In this embodiment, the power source component 2 includes a cylinder 3 installed on the top surface of the mounting base 1, and the cylinder 3 is telescopically connected to the spindle piston rod 4 at one end toward the needle long plate fixing seat 5, and the spindle piston rod 4 drives the sharp main cutter 13 at the end away from the cylinder 3.
[0039] In this embodiment, a travel slideway 6 is integrally formed inside the needle long plate fixing seat 5 , so that the needle long plate fixing seat 5 has a U-shaped structure.
[0040] In this embodiment, stepped slides 11 are integrally formed above the travel slide 6 and at the top ends of the inner walls on both sides of the needle long plate fixing seat 5 .
[0041] In this embodiment, the travel slide 6 and the stepped slide 11 form a T-shaped chute, within which a T-shaped travel block 12 is slidably connected. The T-shaped chute structure formed by the T-shaped travel block 12, the travel slide 6, and the stepped slide 11 provides excellent guidance and stability when the T-shaped travel block 12 slides within the needle length plate holder 5. This not only ensures the linear motion accuracy of the sharp main cutter 13, but also enhances the lateral force resistance of the entire sliding assembly, achieving high-precision guidance and structural self-stabilization during the operation of the cutter, thereby preventing the cutter from deflecting, jamming, and even wear and tear, thereby extending the service life of the equipment.
[0042] In this embodiment, the end of the spindle piston rod 4, distal from the cylinder 3, is fixedly connected to a T-shaped travel block 12, enabling the cylinder 3 to drive the telescopic movement of the spindle piston rod 4. This telescopic movement of the spindle piston rod 4, in turn, causes the T-shaped travel block 12 to reciprocate linearly within the slot of the needle plate holder 5. The fixed connection between the spindle piston rod 4 and the T-shaped travel block 12 allows the telescopic movement of the cylinder 3 to be directly converted into linear reciprocating motion of the T-shaped travel block 12 and the sharp main cutting blade 13. This connection also drives the coordinated operation of the entire sliding assembly within the slot, achieving an integrated design of power transmission and guide structures, resulting in the unexpected technical benefits of a compact structure, high transmission efficiency, and rapid response.
[0043] In this embodiment, the sharp main cutter 13 is integrally connected to the end of the T-shaped travel block 12 facing away from the main shaft piston rod 4.
[0044] In this embodiment, the top surfaces of the T-shaped travel block 12 and the sharp main cutter 13 are flush with the top surface of the needle length plate fixing seat 5, and the top surfaces of the T-shaped travel block 12 and the sharp main cutter 13 abut against the bottom surface of the needle length fixing plate 7. By designing that the bottom surface of the needle length fixing plate 7 is in close contact with the top surfaces of the T-shaped travel block 12 and the sharp main cutter 13, the needle length fixing plate 7 not only serves to locate the needle pins, but also serves as an auxiliary guide and pressure limiter for the T-shaped travel block 12 and the sharp main cutter 13 during the operation of the cutter, thus achieving the dual functions of positioning and guiding, and achieving the additional technical effect of enhancing the stability of the cutter operation and preventing the cutter from floating or deflecting.
[0045] In this embodiment, both sides of the top surface of the needle length fixing plate 7 are connected to the top surface of the needle length plate fixing seat 5 through locking bolts 8.
[0046] In this embodiment, two air pipe joints 10 are symmetrically mounted on the outer wall of the cylinder 3. The air pipe joints 10 are connected to the air compressor in the workshop through air pipes and control the introduction and discharge of compressed air through air valves. The two air pipe joints 10 are respectively the air inlet pipe and the exhaust pipe.
[0047] Working principle:
[0048] The transformer skeleton pin needle cutting machine device fixes the mounting base 1 on the work surface of the workshop to ensure the stability of the entire device, installs a power source component 2, namely a cylinder 3 and a spindle piston rod 4 assembly, at one end of the mounting base 1, and installs a needle long plate fixing seat 5 at the other end of the mounting base 1, which is provided with a stroke slide 6 and a stepped slide 11 structure; the T-shaped stroke block 12 is slidably installed in the T-shaped slide groove formed by the stroke slide 6 and the stepped slide 11 inside the needle long plate fixing seat 5, and the sharp main cutter 13 is integrally connected to one end of the T-shaped stroke block 12, and its top surface is flush with the top surface of the needle long plate fixing seat 5.
[0049] One end of the spindle piston rod 4 is connected to the cylinder 3, and the other end is fixedly connected to the T-shaped travel block 12. The needle length fixing plate 7 is removably mounted on top of the needle length plate fixing base 5 and secured to the base 5 by a locking bolt 8. The bottom surface of the needle length fixing plate 7 fits tightly against the top surface of the T-shaped travel block 12 and the sharp main cutting blade 13, providing both compression and guidance. A needle length plate positioning hole 9 is provided on the top surface of one end of the needle length fixing plate 7 for inserting the pins of the transformer frame.
[0050] Two air pipe connectors 10 are symmetrically mounted on the outer wall of the cylinder 3, serving as an air inlet and an air outlet, respectively. These connectors are connected to an air compressor in the workshop via air pipes, and the introduction and discharge of compressed air are controlled by an air valve. In this embodiment, the air valve is a foot controller 14.
[0051] The operator places the transformer frame to be processed above the needle length fixing plate 7, inserting the pins into the positioning holes 9 of the needle length fixing plate to precisely position the pins. The operator then opens the air valve and introduces compressed air into the air inlet of the cylinder 3, pushing the spindle piston rod 4 forward. The spindle piston rod 4 then drives the T-shaped travel block 12 forward along the slideway, thereby driving the sharp main cutter 13 forward. As the sharp main cutter 13 advances, it aligns with the pins in the needle length fixing plate 7, severing the inserted pins. At this point, the exhaust port of the cylinder 3 opens, allowing the compressed air to escape. The spring or pressure differential within the cylinder retracts the spindle piston rod 4. This retraction drives the T-shaped travel block 12 and sharp main cutter 13 back to their initial positions, completing a needle cutting cycle. These steps can be repeated to achieve continuous needle cutting.
[0052] When pins of different lengths or spacings need to be processed, the locking bolts 8 can be loosened and the pin length fixing plate 7 with different pin length plate positioning holes 9 can be replaced to adapt to transformer frames of different specifications.
