DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2The utility model provides a technical solution: a transformer coil shaping device, including a base 1, a bracket 17 is fixedly installed on the bottom surface of the base 1, a motor 2 is installed on the bottom surface of the base 1, the output end of the motor 2 passes through the base 1 and extends to the top of the base 1, a groove 4 is opened on the surface of the base 1, a rotating plate 3 is arranged in the groove 4, the rotating plate 3 is fixedly installed on the output end of the motor 2, a clamp 5 is installed on the surface of the rotating plate 3, a correction structure is installed on one side of the surface of the base 1, and a cleaning structure is installed on the other side of the surface of the base 1.

[0016] In the process of processing and manufacturing the transformer, first, it is necessary to bend the copper or aluminum stranded wire of good quality into the shape of a circular coil, and then stretch the surface of the coil through a wire stretching machine to make the surface of the coil smooth and flat. During the stretching process, it is necessary to control the stretching force to avoid damaging the coil itself. The two ends of the coil need to be shaped to facilitate the installation of the connecting terminals. Generally, the two ends of the coil need to be silver-plated to enhance the contact between the coil and the terminal and improve the current transmission efficiency. The iron core with the coil installed is placed in the groove 4 and located on the rotating plate 3. The iron core is fixed with a clamp 5, and the external power supply of the motor 2 is turned on, so that the motor 2 drives the rotating plate 3 to rotate, and at the same time drives the iron core and the coil to rotate together. The coil on the outer wall of the iron core is trimmed using a correction structure. After the shaping is completed, the coil needs to be cleaned using a cleaning structure. The oxide layer and other dirt need to be removed from the surface of the copper wire, and then it is sprayed with paint to protect the surface of the coil from moisture, corrosion, etc., and to improve its aesthetics.

[0017] Specifically, one end of an electric push rod 15 is fixedly mounted on the surface of the base 1 , and the other end of the electric push rod 15 is fixedly mounted on the push plate 16 .

[0018] After correction, the clamp 5 stops clamping the iron core and starts the electric push rod 15. The electric push rod 15 continuously extends and pushes the push plate 16. The push plate 16 is arc-shaped and can push the iron core to move along the direction of the groove 4. At the position of the groove 4, a conveyor belt or other transportation tool is used to directly transport the corrected transformer semi-finished product to the next processing point for further processing.

[0019] Specifically, the correction structure includes a vertical rod 18, which is fixedly mounted on the base 1. One end of a cylinder 6 is fixedly mounted on the side of the vertical rod 18. There are three cylinders 6. The other ends of the three cylinders 6 are fixedly mounted with springs 8. The outer walls of the three springs 8 are fixedly sleeved with rubber blocks 9.

[0020] The correction structure can perform knocking correction on the coil on the iron core, start the motor 2 to drive the rotating plate 3 to rotate, and the rotating plate 3 drives the iron core and the coil to rotate together through the clamp 5. At the same time, start the three cylinders 6 to work together, and the cylinder 6 continuously extends to push the top plate 7 close to the coil. The rubber block 9 is pushed onto the coil. The rubber block 9 is deformed due to its own elastic properties. Under the push of the cylinder 6, the surface of the rubber block 9 is arc-shaped and fits the coil, so that the coil fits the iron core more closely, thereby achieving the purpose of correction. The spring 8 is fixed at a position close to the end of the cylinder 6. The spring 8 can undergo elastic deformation to enhance the elastic effect of the rubber block 9, making it fit the coil more closely. As the iron core continues to rotate, the cylinder 6 continuously extends and shortens to make the surface of the coil smooth, thereby achieving the purpose of correction.

[0021] Specifically, the surface of the rubber block 9 is wrapped with a silicone pad 10 .

[0022] A layer of silicone pad 10 is wrapped on the surface of the rubber block 9. The silicone pad 10 is softer in texture and can reduce the wear between the rubber block 9 and the coil.

[0023] Specifically, the cleaning structure includes a slide groove 11, which is opened on the base 1. A slider 12 is slidably clamped on the inner wall of the slide groove 11. A support frame 13 is fixedly installed on the surface of the slider 12. A sponge strip 14 is fixedly installed on the side of the support frame 13 close to the rotating plate 3.

[0024] The cleaning structure is used together with the shaping structure, and a slider 12 and a slide groove 11 with damping are selected. During use, the slider 12 is pushed to move in the slide groove 11, and the slider 12 drives the support frame 13 to move together until the sponge strip 14 on the side of the support frame 13 fits onto the coil. As the rotating plate 3 drives the iron core and the coil on the transformer to rotate together, it constantly contacts the sponge strip 14. The sponge strip 14 wipes the dust and oxide layer on the surface of the coil, making it convenient to directly carry out subsequent processing procedures such as painting after shaping.

[0025] Specifically, the support frame 13 is triangular in shape.

[0026] The support frame 13 is in a three-star shape, has good stability, and can stably support the sponge strip 14.

[0027] Working principle: place the iron core with the coil installed in the groove 4, on the rotating plate 3, fix the iron core with the clamp 5, turn on the external power supply of the motor 2, so that the motor 2 drives the rotating plate 3 to rotate, and drives the iron core and the coil to rotate together, and use the correction structure to trim the coil on the outer wall of the iron core. After the shaping is completed, the coil needs to be cleaned using the cleaning structure, the oxide layer and other dirt need to be removed from the surface of the copper wire, and then it is sprayed with paint.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
