Description

Technical Field

[0001] The utility model belongs to the processing of electrical components, and in particular relates to an adjustable fixture for bending inductor coil pins during the inductor manufacturing process. Background Art

[0002] An inductor is an electronic component whose core function is to convert electrical energy into magnetic energy and store it. Its basic structure includes a coil, which can be single-layer or multi-layer, usually wound with an insulated wire (such as enameled wire or yarn-covered wire). A large concentrated magnetic flux can be generated inside the inductor, and when the current changes greatly, it can withstand a large self-inductance voltage.

[0003] In the actual production process of inductors, due to various process technology requirements, it is often necessary to bend the pins of the inductor coils to varying degrees. Currently, the bending of the inductor coil pins is often done manually. Although manual bending can meet various bending requirements, it has poor consistency and low efficiency. Therefore, there is an urgent need for auxiliary jigs that can assist manual bending in order to improve consistency and efficiency. Utility Model Content

[0004] The utility model aims to overcome the problems of poor consistency and low efficiency in manual bending of existing inductor coil pins, and to provide an adjustable bending fixture for inductor coil pins with a simplified structure, which can effectively improve the consistency and efficiency of manual bending and can adapt to the requirements of different pin bending sections.

[0005] The utility model solves the technical problem by adopting a technical solution: an inductor coil pin adjustable bending fixture comprises a base, a workbench, and a turntable, a support frame is provided on one side of the workbench, the support frame is fixed to the base, the turntable is located between the workbench and the base, the turntable and the base are movably connected, the workbench, the base and the turntable are parallel to each other, a baffle I is fixedly connected to the workbench, a through hole is provided on the baffle I, a baffle II is provided on the workbench, a plurality of slots are provided at intervals on the workbench, the baffle II is clamped with the workbench, the baffle II is perpendicular to the baffle I, a plurality of arc-shaped movable holes are provided at intervals on one side of the baffle II, the movable holes are concentric with the turntable, a plurality of threaded holes are provided on the turntable, the threaded holes are matched one by one with the movable holes, a bending rod is provided on the turntable, one end of the bending rod is vertically threadedly connected to the turntable, and a turning handle is provided on the turntable.

[0006] Optionally, the baffle I is "L"-shaped, and a wire groove is formed between the baffle I, the baffle II and the base, and the through hole and the wire groove are on the same axis.

[0007] Optionally, a cylindrical bending block is provided at one end of the baffle II.

[0008] The usage and principle of the utility model are as follows: insert the inductor coil pin to be bent into the perforation, place the pin line on the workbench, and locate it on the upper side of the baffle II, and extend the pin line toward the active hole. At this time, hold the handle and turn the turntable, the turntable drives the bending rod to move in the active hole, and the bending rod drives one end of the pin line to move. Due to the resistance of the baffle II, the pin line is bent, and different bends occur according to different rotation angles of the turntable, so that the manual bending efficiency is higher and the consistency is better by adopting the form of auxiliary jigs;

[0009] When it is necessary to bend other segments of the lead wire, remove the baffle II, move it forward for a distance, and fix it to the workbench through the card slot on the workbench. Then rotate the bending rod, remove it from the current active hole, put it into other active holes, and connect the bending rod to the turntable through the threaded hole matching the active hole. Then, rotate the turntable to bend the current segment of the lead wire.

[0010] Since the front end of the pin line is prone to unnecessary arching during the bending process, baffle I is made "L"-shaped, and a wire groove is formed between baffles I, baffle II and the base. The perforation and the wire groove are on the same axis. This measure is used to limit the displacement of the front end of the pin line and make the front end of the pin line as straight as possible.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure, can effectively improve the consistency and efficiency of manual bending, and can adapt to the requirements of different bending sections of the pin.
