[0019] In the following, the utility model will be described in detail with reference to the drawings and in combination with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0020] As Figures 1 to 4In the embodiment of the automatic cored wire production equipment of the present utility model shown, the automatic cored wire production equipment includes a pipe coiling box 1 and a feeding pipe 2. One end of the pipe coiling box 1 is provided with a conical steel strip inlet 3, and the other end of the pipe coiling box 1 is provided with a pipe coiling outlet 4. The feeding pipe 2 penetrates through the steel strip inlet 3 and the pipe coiling outlet 4. A pipe coiling assembly is arranged in the pipe coiling box 1. The feeding pipe 2 is provided with a plurality of feeding ports 5 at one end of the steel strip inlet 3. A rotating shaft 6 is arranged in the feeding pipe 2, and a screw 7 is fixedly connected to the rotating shaft 6.

[0021] Specifically, the steel strip enters the pipe coiling box 1 from the steel strip inlet 3. Affected by the conical shape of the steel strip inlet 3, the steel strip curls to form a semi-tubular shape. After the pipe coiling box 1 processes the steel strip, a closed pipeline comes out from the pipe coiling outlet 4. The discharge port of the feeding pipe 2 extends into the pipe coiling box 1 and is rolled into the pipe. The rotating shaft 6 is started to rotate and drives the screw 7 to inject powder into the pipeline. The core powder will not leak, and the core powder is filled densely under the extrusion of the screw 7. The plurality of feeding ports 5 can be suitable for different core powder materials.

[0022] In an embodiment of the present application, preferably, the pipe coiling assembly includes a plurality of diameter adjusting wheel groups 8. The diameter adjusting wheel groups 8 are rotatably arranged on both sides of the feeding pipe 2. The groove diameters of the plurality of diameter adjusting wheel groups 8 gradually decrease in the direction of the pipe coiling outlet 4, so as to gradually roll the steel strip into a tubular shape and gradually overlap the two edges of the steel strip.

[0023] In an embodiment of the present application, preferably, the pipe coiling assembly includes an inner pipe coiling mold 9. The inner pipe coiling mold 9 is sleeved on the feeding pipe 2 and fixedly connected to the feeding pipe 2. One end of the inner pipe coiling mold 9 extends out of the steel strip inlet 3, so as to prevent the steel strip from deforming during pipe coiling.

[0024] In an embodiment of the present application, preferably, the pipe coiling assembly further includes an outer edge sealing mold 10. A reduced diameter section 11 is provided at the other end of the inner pipe coiling mold 9. The outer edge sealing mold 10 is sleeved on the reduced diameter section 11. The taper of the outer edge sealing mold 10 is the same as that of the reduced diameter section 11, so as to further reduce the diameter of the pipeline during edge sealing.

[0025] In an embodiment of the present application, preferably, a wheel opening 12 is provided at the front end of the outer edge sealing mold 10. A grooving wheel 13 is rotatably connected to the wheel opening 12. A groove 14 adapted to the grooving wheel 13 is provided on the inner pipe coiling mold 9, so as to press out indentations on the overlapping edges of the steel strip. When the outer edge sealing mold 10 further reduces the diameter of the pipeline, a snap edge is formed by extrusion at the indentation part, so as to avoid cracking during reel packaging.

[0026] In an embodiment of the present application, preferably, a bearing ring 15 is fixedly connected to the outer edge sealing mold 10. A spring 16 is sleeved on the outer edge sealing mold 10. One end of the spring 16 abuts against the bearing ring 15, and the other end abuts against the pipe coiling box 1 around the pipe coiling outlet 4. When threading for the first time, the outer edge sealing mold 10 is pushed towards the pipe coiling box 1 so that the pipeline passes under the grooving wheel 13.

[0027] In one embodiment of the present application, preferably, a motor 17 is fixedly connected to one end of the feeding pipe 2 at the feeding port 5, and the driving shaft of the motor 17 is fixedly connected to the rotating shaft 6 for driving the rotating shaft 6 to rotate and inject materials into the pipeline.

[0028] In summary, for the automatic cored wire production equipment in the above embodiments of the present utility model, specifically, the steel strip enters the pipe coiling box 1 from the steel strip inlet 3. Affected by the taper of the steel strip inlet 3, the steel strip curls to form a semi-tubular shape. The diameter of the pipeline is adjusted by the diameter adjusting wheel set 8 in the pipe coiling box 1. Through the action of the grooved wheel 13 on the edge sealing outer die 10 and the groove 14 on the inner pipe coiling die 9, the pipeline is sealed. The discharge port of the feeding pipe 2 extends into the pipe coiling box 1 and is wound into the pipe. The motor 17 is started to drive the rotating shaft 6 to rotate and drive the screw 7 to inject core powder into the pipeline. The core powder will not leak. The core powder is filled densely under the extrusion of the screw 7. Multiple feeding ports 5 can be applicable to different core powder materials. The device extends the feeding pipe 2 into the pipe coiling box 1 and injects core powder into the completed coiled pipeline. Using the screw 7 to extrude and convey the core powder inward can avoid the insufficient core powder injection affecting the quality of the cored wire.
