Technical Field

[0001] The utility model belongs to the processing of electrical components, and in particular relates to a U-shaped bending punching jig suitable for copper wires used in the production of inductors or transformers. Background Art

[0002] Inductor coils are mainly composed of wires wound around an insulating tube, the wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. Inductor coils are widely used in various electronic devices, such as radio transceivers, transformers, power supplies, oscillators, etc.

[0003] At present, in the process of making various types of inductors or transformers using inductor coils, enameled copper wires or sheathed copper wires of different lengths are needed, and they often need to be bent differently due to design requirements. The existing copper wire U-bending is done manually with pliers, which is inefficient and has poor consistency. Therefore, it is necessary to design appropriate auxiliary tooling to improve bending efficiency and consistency. Utility Model Content

[0004] The utility model aims to overcome the problems of low efficiency and poor consistency of existing copper wire U-bending, and to provide a copper wire U-bending stamping fixture with a simplified structure, high bending efficiency and high bending consistency.

[0005] The utility model adopts a technical solution to solve its technical problems: a copper wire U-shaped bending stamping fixture, comprising a base, a stamping head and a stamping table, the stamping table is arranged on the base, the stamping head is located above the stamping table, the stamping table is composed of a fixed table and a movable table, the fixed table is fixedly connected to the base, the movable table is located on one side of the fixed table, the movable table is slidably connected to the base, a limit screw is arranged on the movable table, a stamping groove is formed between the fixed table and the movable table, the stamping groove matches the stamping head, a plurality of copper wire placement grooves are arranged on the fixed table and the movable table at intervals, and the copper wire placement grooves on the fixed table correspond to the copper wire placement grooves on the movable table one by one.

[0006] Optionally, the punching head is a plastic head, and a PVC rubber pad is provided at the bottom of the punching groove and the copper wire placement groove.

[0007] Optionally, a slider is provided at the bottom of the movable platform, a slide rail is provided on the base, and the movable platform is slidably connected to the base via the slider and the slide rail.

[0008] The usage and principle of the utility model are as follows: according to the design requirements of the copper wire U-shaped forming foot pitch, the movable block is slid to make the punching groove reach the specified width, the limit screw is rotated to make the bottom of the limit screw abut against the base to limit the movement of the movable block, then, a punching head matching the punching groove is selected and connected to the punching machine, the punching head is located above the punching groove, a plurality of copper wires to be bent are placed in the copper wire placement groove, the punching machine is started, the punching head moves down, and the copper wire is punched into a U shape; in order to prevent the copper wire from breaking, the punching head adopts a plastic head, and PVC rubber pads are laid at the bottom of the punching groove and the copper wire placement groove.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simplified structure and can effectively improve the efficiency and consistency of the U-shaped bending of the copper wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 This is a schematic diagram of the top view structure of the utility model;

[0012] The components described in the accompanying drawings are marked as follows: base 1, punching head 2, punching table 3, fixed table 4, movable table 5, limit screw 6, punching groove 7, copper wire placement groove 8, PVC rubber pad 9. DETAILED DESCRIPTION

[0013] Embodiment 1, below combines Figure 1 and Figure 2 To further illustrate the utility model, the copper wire U-shaped bending stamping fixture includes a base 1, a stamping head 2 and a stamping table 3. The base is a cube, the stamping table is arranged on the base, the stamping head is located above the stamping table, the stamping table is composed of a fixed table 4 and a movable table 5, the fixed table and the movable table are cubes, the fixed table and the base are integrally formed, the movable table is located on one side of the fixed table, a slider is provided at the bottom of the movable table, the slider is convex, a slide rail is provided on the base, the cross section of the slide rail is convex, the movable table is slidably connected to the base through the slider and the slide rail, The movable table makes horizontal linear motion along the left and right directions on the base. A limit screw 6 is provided on the movable table. The limit screw passes through the movable table vertically and is threadedly connected to the movable table. A stamping groove 7 is formed between the fixed table and the movable table. The stamping groove is a rectangular groove. The stamping head is a rectangular parallelepiped.
