Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and in particular to a transformer frame and inductor pin cutting device. Background Technology

[0002] With the rapid development of the electronics manufacturing industry, the demand for transformers, as key components, is increasing daily. In the transformer production process, precisely cutting the transformer frame and inductor pins is a crucial step in ensuring its performance and quality. However, traditional manual or semi-automatic pin-cutting methods are not only inefficient and labor-intensive, but also struggle to guarantee the consistency and precision of the cuts. To overcome these problems, various automated pin-cutting machines have emerged on the market. Although existing automated pin-cutting machines have improved work efficiency and processing accuracy to some extent, they still have some shortcomings in practical applications.

[0003] The transformer frame is one of the core components in transformer manufacturing, and its pins often need to be precisely cut according to actual assembly requirements after winding. To improve production efficiency and processing accuracy, pin cutting equipment has gradually replaced the traditional manual cutting method. However, many problems still exist in practical applications. For example, most existing pin cutting machines do not have a dedicated pin positioning structure and rely on the operator's experience for placement, which easily leads to inconsistent pin lengths. If the pin insertion position is off, the cutter cannot accurately align the pin, resulting in uneven cuts and inaccurate dimensions, or even damage to the transformer frame. Utility Model Content

[0007] The power source component is mounted on the top surface of one end of the mounting base;

[0008] The needle plate fixing seat is installed on the top surface of the other end of the mounting base, and the power execution end of the power source component moves linearly back and forth in the needle plate fixing seat.

[0010] The needle length fixing plate is detachably installed on the top surface of the needle length plate fixing seat and is located directly above the sharp main cutting blade;

[0011] The needle length fixing plate has a needle length plate positioning hole at one end of its top surface for inserting transformer bobbin and inductor pins. When the pins of the transformer bobbin are inserted into the needle length plate positioning hole, the pins of the transformer bobbin are cut off by the sharp main cutter sliding back and forth in a straight line in the needle length plate fixing seat. A feeding port is provided on one side of the needle length plate fixing seat and on the top surface of the mounting base. A waste needle container for holding waste needles is provided below the feeding port and on the bottom surface of the mounting base. An infrared sensor is installed on one side of the needle length plate positioning hole and on the top surface of the needle length fixing plate. A controller is provided on one side of the infrared sensor.

[0012] In a preferred embodiment of this solution, the power source component includes a cylinder mounted on the top surface of the mounting base. A main shaft piston rod is telescopically connected to one end of the cylinder facing the needle plate fixing seat, and the end of the main shaft piston rod away from the cylinder drives the sharp main cutting blade.

[0013] In this preferred embodiment, the needle plate fixing seat has an integrally formed travel slide, making the needle plate fixing seat U-shaped.

[0014] In this preferred embodiment, stepped slides are integrally formed on the top of the inner walls on both sides of the travel slide and located above the needle plate fixing seat.

[0015] In a preferred embodiment of this design, the travel slide and the stepped slide form a T-shaped groove, in which a T-shaped travel block is slidably connected.

[0016] In this preferred embodiment, the end of the main shaft piston rod away from the cylinder is fixedly connected to the T-shaped stroke block, so that the cylinder drives the main shaft piston rod to extend and retract, and the extension and retraction of the main shaft piston rod causes the T-shaped stroke block to move linearly back and forth in the slide groove of the needle plate fixing seat.

[0017] In this preferred embodiment, the sharp main cutting blade is integrally connected to the end of the T-shaped stroke block facing away from the main shaft piston rod.

[0018] In this preferred embodiment, the top surfaces of the T-shaped travel block and the sharp main cutter are flush with the top surface of the needle length plate fixing seat, and the top surfaces of the T-shaped travel block and the sharp main cutter abut against the bottom surface of the needle length fixing plate.

[0019] In this preferred embodiment, both sides of the top surface of the needle length fixing plate are connected to the top surface of the needle length plate fixing seat by locking bolts.

[0020] In this preferred embodiment, two air pipe connectors are symmetrically installed on the outer wall of the cylinder. The air pipe connectors are connected to the air compressor in the workshop through air pipes and the introduction and discharge of compressed air are controlled by a solenoid valve.

[0021] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0022] The transformer frame and inductor pin cutting machine is designed with a power source component installed at one end of the mounting base, which drives the sharp main cutter to slide linearly back and forth in the pin length plate fixing seat. This design allows the cutting action to be driven by a cylinder, resulting in fast power response and high control precision. This achieves automated operation of the cutting action, thereby improving work efficiency and reducing manual labor intensity.

[0023] The design, which involves a sharp main cutter slidingly mounted in the needle length plate fixing seat and driven by a power source component to perform linear reciprocating motion, ensures stable guidance and precise stroke control during the needle cutting process. This avoids cutter deviation or jamming, achieving rapid and accurate cutting of the needle feet and resulting in a smooth and consistent cutting effect.

[0024] The design of the needle length fixing plate, which can be detachably installed on the top surface of the needle length plate fixing seat and is located directly above the sharp main cutter, allows the needle to be accurately positioned through the needle length plate positioning hole on the needle length fixing plate before being cut. This avoids problems such as needle offset or inconsistent insertion depth, achieves standardization and consistency in the processing process, and improves the product qualification rate.

[0025] By setting a positioning hole on the top surface of the needle length fixing plate, the needles of the transformer bobbin can be positioned immediately upon insertion, without the need for additional clamps or positioning devices. This achieves rapid clamping and efficient processing, simplifying the operation process and improving the production cycle. Attached Figure Description

[0033] In the following description, numerous specific details are set forth in order 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 can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0034] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0035] This embodiment provides, for example Figures 1 to 4 The device shown is a transformer frame and inductor pin cutting machine, 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 blade 13, and a needle length fixing plate 7.

[0036] In this embodiment, the mounting base 1 is installed on the workshop workbench. The design of fixing the mounting base 1 to the workbench provides a stable foundation for the entire needle-cutting device, preventing uneven cuts or processing errors caused by equipment shaking during the cutting process. This ensures stable operation of the entire device, improving processing accuracy and production safety. The power source component 2 is installed on the top surface of one end of the mounting base 1; the needle length plate fixing seat 5 is installed on the top surface of the other end of the mounting base 1, and the power actuator of the power source component 2 moves linearly back and forth within the needle length plate fixing seat 5. The symmetrical layout of the needle length plate fixing seat 5 at the other end of the mounting base 1, in conjunction with the power source component 2, results in a compact and rationally designed device. This not only saves space but also facilitates equipment maintenance and tool replacement, optimizing space utilization and enabling easy integration into automated production lines. The sharp main cutting blade 13 is slidably installed in the needle length plate fixing seat 5, and the power actuator of the power source component 2 drives the sharp main cutting blade 13 to slide linearly back and forth within the needle length plate fixing seat 5.

[0037] In this embodiment, the needle length fixing plate 7 is detachably installed on the top surface of the needle length plate fixing base 5 and located directly above the sharp main cutter 13. One end of the top surface of the needle length fixing plate 7 is provided with a needle length plate positioning hole 9 for inserting the transformer skeleton and inductor pins. When the pins of the transformer skeleton are inserted into the needle length plate positioning hole 9, the pins of the transformer skeleton are cut off by the sharp main cutter 13 sliding linearly back and forth in the needle length plate fixing base 5. A feeding port 14 is provided on one side of the needle length plate fixing base 5 and on the top surface of the mounting base 1. A waste needle container 15 for holding waste needles is provided below the feeding port 14 and on the bottom surface of the mounting base 1. When the power source component 2 drives the main shaft piston rod 4 to extend and cut the pins through the sharp main cutter 13, the cut pins fall into the required waste needle container 15 through the needle feeding port 17. An infrared sensor 16 is installed on one side of the needle length plate positioning hole 9 and on the top surface of the needle length fixing plate 7. A controller 17 is provided on one side of the infrared sensor 16. The controller 17 is connected to the solenoid valve of the cylinder 3. The controller 17 is a PLC. The infrared sensor 16 detects a human body entering the sensing area and outputs a signal to the controller 17. After the controller 17 judges, it outputs a control signal to drive the solenoid valve. The solenoid valve switches the air path, causing the piston rod 4 of the main shaft of the cylinder 3 to extend or retract. After the human body leaves, it can automatically or after a delay reset and close the cylinder 4.

[0038] In this embodiment, the power source component 2 includes a cylinder 3 mounted on the top surface of the mounting base 1. The end of the cylinder 3 facing the needle plate fixing seat 5 is connected to a main shaft piston rod 4, and the end of the main shaft piston rod 4 away from the cylinder 3 drives the sharp main cutting blade 13.

[0039] In this embodiment, the needle plate fixing seat 5 has an integrally formed travel slide 6 inside, making the needle plate fixing seat 5 have a U-shaped structure.

[0040] In this embodiment, stepped slides 11 are integrally formed on the top of the inner walls on both sides of the travel slide 6 and located on the needle plate fixing seat 5.

[0041] In this embodiment, the travel slide 6 and the stepped slide 11 form a T-shaped groove, in which a T-shaped travel block 12 is slidably connected. The design of the T-shaped groove structure formed by the T-shaped travel block 12, the travel slide 6, and the stepped slide 11 ensures good guidance and stability when the T-shaped travel block 12 slides inside the needle plate fixing seat 5. This not only guarantees the linear motion accuracy of the sharp main cutter 13 but also enhances the lateral force resistance of the entire sliding assembly. It achieves high-precision guidance and structural self-stabilization during cutter operation, preventing cutter deviation, jamming, and even wear damage, thereby extending the equipment's service life.

[0042] In this embodiment, the end of the main spindle piston rod 4 furthest from the cylinder 3 is fixedly connected to the T-shaped stroke block 12, so that the cylinder 3 drives the main spindle piston rod 4 to extend and retract. The extension and retraction of the main spindle piston rod 4 drives the T-shaped stroke block 12 to reciprocate linearly in the groove of the needle plate fixing seat 5. Through the design of the main spindle piston rod 4 being fixedly connected to the T-shaped stroke block 12, the extension and retraction of the cylinder 3 is directly converted into the linear reciprocating motion of the T-shaped stroke block 12 and the sharp main cutting blade 13. At the same time, this connection structure also drives the entire sliding assembly to operate in coordination in the groove, realizing the integrated design of power transmission and guiding structure, and achieving unexpected technical effects of compact structure, high transmission efficiency, and fast response speed.

[0043] In this embodiment, the sharp main cutting blade 13 is integrally connected to one end of the T-shaped stroke 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. Through the design of the bottom surface of the needle length fixing plate 7 tightly abutting against 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 as a needle positioning function, but also provides auxiliary guidance and clamping limit for the T-shaped travel block 12 and the sharp main cutter 13 during the cutter's operation. This achieves the dual functions of positioning and guiding, and additionally enhances the stability of the cutter's operation, preventing the cutter from floating or deviating.

[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 by locking bolts 8.

[0046] In this embodiment, two air pipe connectors 10 are symmetrically installed on the outer wall of the cylinder 3. The air pipe connectors 10 are connected to the air compressor in the workshop through air pipes and the introduction and discharge of compressed air are controlled by a solenoid valve. The two air pipe connectors 10 are the intake pipe and the exhaust pipe, respectively.

[0047] Working principle:

[0048] The transformer frame and inductor pin cutting machine device fixes the mounting base 1 on the workbench of the workshop to ensure the stability of the entire device. The power source component 2, namely the cylinder 3 and the main shaft piston rod 4 assembly, is installed at one end of the mounting base 1. The needle long plate fixing seat 5 is installed at the other end of the mounting base 1. The needle long plate fixing seat 5 is provided with a stroke slide 6 and a stepped slide 11 structure inside. The T-shaped stroke block 12 is slidably installed in the T-shaped groove formed by the stroke slide 6 and the stepped slide 11 inside the needle long plate fixing seat 5. The sharp main cutting blade 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 main shaft piston rod 4 is connected to the cylinder 3, and the other end is fixedly connected to the T-shaped stroke block 12. The needle length fixing plate 7 is detachably installed on the top of the needle length plate fixing seat 5 and fastened to the needle length plate fixing seat 5 by locking bolts 8. The bottom surface of the needle length fixing plate 7 is in close contact with the top surface of the T-shaped stroke block 12 and the sharp main cutter 13, which serves to press and guide. A needle length plate positioning hole 9 is opened on the top surface of one end of the needle length fixing plate 7 for inserting the needles of the transformer bobbin.

[0050] Two air pipe connectors 10 are symmetrically installed on the outer wall of cylinder 3, serving as the air inlet and exhaust port respectively. The air pipe connectors 10 are connected to the air compressor in the workshop through air pipes, and the introduction and discharge of compressed air are controlled by solenoid valves.

[0051] The operator places the transformer bobbin to be processed above the needle length fixing plate 7, inserting the needle into the positioning hole 9 of the needle length plate to achieve precise needle positioning. The air valve is opened, allowing compressed air to enter the air inlet of cylinder 3, pushing the main shaft piston rod 4 forward. The main shaft piston rod 4 drives the T-shaped stroke block 12 forward along the slide groove, thereby advancing the sharp main cutter 13 forward. When the sharp main cutter 13 advances forward, it aligns with the needle position in the needle length fixing plate 7, cutting off the inserted needle. At this time, the exhaust port of cylinder 3 opens, releasing compressed air. The internal spring or air pressure difference causes the main shaft piston rod 4 to retract. The retraction of the main shaft piston rod 4 drives the T-shaped stroke block 12 and the sharp main cutter 13 back to their initial positions, completing one needle cutting cycle. The above steps can be repeated to achieve continuous needle cutting operations.

[0052] When it is necessary to process pins of different lengths or different spacings, the locking bolt 8 can be loosened and the pin length fixing plate 7 with pin length plate positioning holes 9 of different sizes can be replaced to adapt to transformer bobbins of different specifications.
