Description

Technical Field

[0001] The utility model relates to the technical field of steel metallurgy production, in particular to an automatic lifting and swinging combined wire feeding device for cored wires. Background Art

[0002] The development of cored wire feeders began in the late 20th century. With advancements in metallurgical technology and increasing demands for steel quality, cored wire feeders have seen rapid development and widespread application. Their highly automated operation significantly reduces manual intervention, and by precisely controlling the speed, depth, and position of the cored wire, they improve alloying element utilization and addition accuracy.

[0003] Modern cored wire feeders have not only improved control accuracy and automation levels, but have also been optimized in terms of feeding speed, adaptability, and ease of maintenance. Their main function is to feed calcium silicon wire, aluminum wire, alloy wire, or cored wire containing various powders into the molten steel in the ladle at a certain speed, smelt the molten steel outside the furnace, and adjust the molten steel composition, thereby significantly improving various indicators such as the morphology of the molten steel inclusions to meet production requirements:

[0004] In conventional wire feeders, due to the fixed position of the guide tube, the core wire is fed into the molten steel at the same position, which easily leads to uneven deoxidation and alloying effects. In addition, the core wire is easily entangled and deformed due to factors such as high temperature or physical collision, resulting in abnormal conditions such as difficulty or inability to feed the core wire, affecting production or process requirements.

[0005] Chinese utility model application number 201921500118.5 discloses a core wire guide device for a wire feeding machine, comprising an adjustment frame and a guide tube. The adjustment frame can move vertically relative to a fixed frame to adjust the height of the guide tube outlet. This utility model achieves height adjustment of the guide tube outlet to ensure smooth feeding of the core wire into the ladle. However, this utility model's core wire guide device cannot change the feeding direction of the cored wire.

[0006] Another Chinese utility model application, application number 201521031160.9, discloses a wire feeder with adjustable height and angle. This utility model reduces the weight of the equipment; at only two-fifths of the original weight, the equipment volume is reduced, laying the foundation for flexible adjustment of the equipment and flexible adaptation to limited space. At the same time, the height of the wire feeder's wire feeding port can be adjusted to change the feeding position of the cored wire; however, this utility model requires frequent movement of the wire feeding port to adjust the feeding angle of the cored wire. Utility Model Content

[0007] In order to solve the problems of element segregation in molten steel after wire feeding and uneven deoxidation effect, the utility model aims to provide a cored wire automatic lifting and swinging combined wire feeding device.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solution: a cored wire automatic lifting and swinging combined wire feeding device, comprising a cored wire rack, the outer side of the cored wire rack is connected to the cored wire, a wire feeding machine is provided on the side of the cored wire rack close to the cored wire, a wire feeding machine is provided on the side of the wire feeding machine away from the cored wire rack, the cored wire passes through the interior of the wire feeding machine and the wire tube, a wire oscillator is provided at the other end of the wire tube, and a lifting frame is provided above the wire oscillator.

[0009] Preferably, two swing arms that can swing up and down are respectively provided on both sides of the interior of the cycloid, and a plurality of swing arm ends are provided with swing arm pulleys, and the swing arm pulley contains a wheel inner bearing. The swing arm and the swing arm pulley are connected by a fixed shaft, and the outer side of the fixed shaft is connected to the inner wall of the wheel inner bearing. The fixed shaft passes through the inner ring of the wheel inner bearing and both sides of the swing arm. The fixed shaft is fixed to both sides of the swing arm by screws and gaskets. A ladle is provided under the cycloid, and molten steel is provided inside the ladle. The outer side of the wire pipe is provided with evenly distributed tube pulleys.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The wire feeding device of the present application can not only realize the lifting and lowering of wire feeding under the premise of fixing the wire feeding machine, but also automatically change the feeding angle of the cored wire, eliminating the need to adjust the height of the wire feeding port of the wire feeding machine back and forth, thereby simplifying the operation of on-site workers; at the same time, since the cored wire is guided by the pulley contact when passing through the wire tube and the cycloidal device, the feeding speed of the cored wire is not affected, thus avoiding the abnormal situation of the cored wire being difficult to feed or not being able to feed, thereby saving manpower and material costs; BRIEF DESCRIPTION OF THE DRAWINGS

The height of the cycloid 6 can be automatically adjusted by the lifting frame 5 to control the swing feeding range of the cored wire 2.

[0022] Two swing arms 7 that can swing up and down are respectively provided on both sides of the interior of the cycloid 6, and a plurality of swing arms 7 are provided at the ends of the swing arm pulleys 10. The swing arm pulleys 10 contain wheel inner bearings 14. The swing arm 7 and the swing arm pulley 10 are connected by a fixed shaft 73. The outer side of the fixed shaft 73 is connected to the inner wall of the wheel inner bearing 14. The fixed shaft 73 passes through the inner ring of the wheel inner bearing 14 and both sides of the swing arm 7. The fixed shaft 73 is fixed on both sides of the swing arm 7 by screws 71 and gaskets 72. A ladle 8 is provided below the cycloid 6, and molten steel 9 is provided inside the ladle 8. The outer side of the wire tube 4 is provided with evenly distributed inner tube pulleys 11. By leaving a gap between the swing arm pulley 10 and the swing arm 7, friction between the two can be avoided; the nut at the upper end of the screw 71 and the gasket 7 under the nut 2, its diameter is larger than the diameter of the fixed shaft 73, and the two ends of the fixed shaft 73 are fixed with screws 71 to effectively prevent the fixed shaft 73 from moving left and right. It should be noted that: the spacing between the two adjacent pulleys should be controlled within 10 cm to avoid the cored wire 2 from colliding with the inner wall of the wire tube 4, ensuring that the cored wire 2 runs smoothly in the wire tube 4; through the provided swing arm pulley 10, when the swing arm 7 is lifted, the swing arm pulley 10 contacts the descending cored wire 2 to reduce friction, ensuring that the feeding speed of the cored wire 2 is not affected, avoiding the abnormal situation of being difficult to feed or not being able to feed, and the morphology of the swing arm pulley 10 is a style with convex sides and concave in the middle. When contacting the cored wire 2, the convex parts on both sides can fix the cored wire 2, avoiding the cored wire 2 from falling off the wheel due to excessive speed;

[0023] A sensor 12 is provided inside the cycloid 6. Two swing arm bases 13 are provided on both sides of the cycloid 6. The swing arm bases 13 are connected to the swing arm 7. A wheel inner bearing 14 is provided inside the swing arm pulley 10 to ensure that the cored wire 2 passes through the cycloid 6 before starting to run, to prevent the cored wire 2 from colliding with the swing arm 7, and to improve the operation accuracy of the equipment.

[0024] A rotating shaft 15 is provided inside the swing arm base 13, and the outer ring of the rotating shaft 15 is fixedly connected to the swing arm base 13.

[0025] Working principle: When the cored wire 2 enters the cycloid 6 through the wire conduit 4, the swing arm 7 starts to work automatically. In order to prevent the cored wire 2 from colliding with the swing arm 7, the swing arms 7 on both sides are in a lowered state before the cored wire 2 enters the cycloid 6. After the cored wire 2 passes through the cycloid 6, the two swing arms 7 on the left are lifted upward, and the two swing arms 7 on the right remain in a lowered state, leaving swing space for the cored wire 2. The left swing arm 7 pushes the cored wire 2 to the right side of the cycloid 6. After a period of time, the left swing arm 7 is lowered and the right swing arm 7 is lifted upward, pushing the cored wire 2 to the left side of the cycloid 6. This cycle repeats itself. The ladle 8 is located below the cycloid 6, and the feeding angle of the cored wire 2 is swung left and right to adjust the position of the feeding molten steel 9.
