Description

Technical Field

[0001] The invention belongs to the technical field of molten steel refining, and in particular relates to a conveying and guiding device for wire feeding. Background Art

[0002] At present, the wire feeding system used in most steel companies' refining furnaces is to place the wire coil on the ground and install the wire feeder on the upper platform. When feeding the wire, the wire is drawn out from the spiral coil and enters the wire feeder through the guide tube and guide wheel. This wire feeding method has certain disadvantages: First, since the wire is formed into a coil by spiral winding and stacking, as the wire feeding progresses, the wire cannot enter the guide tube at the same angle, the wire is unevenly stressed and easily broken. At the same time, the uneven force on the wire will cause shaking before entering the guide tube, causing the spiral stack to loosen, resulting in disordered wire and inability to feed the wire; second, the wire is drawn out from the coil and runs upward, and there will be a certain degree of curvature when entering the wire feeder, which is not conducive to the operation of wire feeding.

[0003] The Chinese patent specification discloses a wire-guiding and conveying wire feeder (publication number: CN 220056922U), and specifically discloses the following contents: comprising a wire feeder, a turntable base is arranged at one end of the wire feeder, a rotating table is arranged inside the turntable base, a protective plate is fixedly arranged on the turntable base, an alloy core wire is placed on the rotating table, and during the core wire is input into the wire feeder, the rotating table rotates to guide the alloy core wire, and the core wire is pulled into the wire feeder at the same angle, the core wire is evenly stressed, and is not easy to break. The utility model has made improvements to the guidance of the core wire, but the core wire often breaks when the rotating table is pulled by the core wire. At the same time, the rotating table will also generate inertia and lose constant rotation, resulting in disorder of the core wire. Summary of the invention

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can have a clearer understanding.

[0023] Embodiment 1

[0024] like Figure 1 As shown, this embodiment includes a conduit 1, which is "L" shaped, and the outer wall of the vertical section thereof is connected to the outer circle of the bearing 2 through a connecting block 5, and the inner circle of the bearing is sleeved with a vertical rod 3. The conduit can rotate freely with the vertical rod as the axis under the action of external force, and the lower end of the vertical rod is connected to a base 4; the outer wall of the vertical section of the conduit is also connected to a plurality of straightening components 6, each group of straightening components is two and is arranged oppositely, such as Figure 6 As shown, the straightening assembly 6 includes a straightening roller 61, which is rotatably connected to a core shaft 62, and the ends of the core shaft are connected to a support frame 63 one by one. The straightening roller has an arc-shaped groove along its circumference, and a part of the straightening roller extends into the conduit through a through hole on the side wall of the conduit, and the support frame is connected to the outer wall of the vertical section of the conduit.

[0025] As a preference of this embodiment, the lower end of the conduit is a bell mouth.

[0026] When using, Figure 7 As shown, the conveying and guiding device of the present invention is placed at the center position of the wire coil 8, and the wire 81 enters from the bell mouth at the lower end of the conduit 1, and passes between the two opposite straightening rollers 61. After being corrected by four groups of straightening components, it is led out from the outlet at the upper end of the conduit 1 into the wire feeding machine to feed the molten steel. In the process of conveying and guiding the wire, the conduit 1 rotates with the vertical rod 3 as the axis through the pulling of the wire, which plays a certain guiding role in the conveyance of the wire. However, as the wire 81 decreases, the height of the wire coil will gradually decrease. Since the height of the conduit is fixed, the angle at which the wire enters the conduit will continue to increase and be unstable, which will cause uneven force on the wire and cause the spiral stacking of the wire coil to loosen or cause the wire to break.

[0027] Embodiment 2

[0028] In order to overcome the above problems, the present invention makes further improvements on the basis of the first embodiment. Figure 2 , Figure 5 As shown, the connecting block 5 includes a guide block 51 and a slider 52. The guide block is connected to the outer wall of the vertical section of the conduit. The guide block has a guide groove with a "T"-shaped cross-section. The slider is slidably connected to the guide groove. The slider is connected to the outer circle of the bearing 2.

[0029] During the process of conveying and guiding the silk thread, the catheter 1 rotates with the vertical rod 3 as the axis by pulling the silk thread. At the same time, due to the action of the guide block 51 and the slider 52, the catheter 1 can slide freely up and down. The catheter will make adaptive changes as the position height of the silk thread changes, so as to maintain the angle at which the silk thread enters the catheter and avoid causing the spiral stacking of the wire coil to become loose. However, this structure places certain requirements on the weight of the catheter, requiring the catheter to be made of lightweight material.

[0030] Embodiment 3

[0031] In order to overcome the above problems, the present invention makes further improvements on the basis of the second embodiment. Figure 3 As shown, this embodiment also includes a lifting component 7, which includes a threaded tube 71 and a thread arranged on the upper section of the vertical pole 3. The threaded tube cooperates with the thread of the upper section of the vertical pole, and the threaded tube is connected to the outer wall of the upper part of the conduit through a connecting rod 72.

[0032] During the process of conveying and guiding the wire, the guide tube 1 rotates with the vertical rod 3 as the axis due to the pulling of the wire. At the same time, due to the combined effect of the threaded tube 71 in the lifting assembly and the thread set on the upper section of the vertical rod 3, the guide tube will move downward while rotating, that is, as the wire gradually decreases, the height of the wire coil will gradually decrease, and the guide tube will also gradually move downward. Figure 3 The attitude changes to Figure 4 posture, so that the angle at which the wire enters the catheter remains constant, avoiding the loosening of the spiral stack of the wire coil and better preventing the wire from being broken.

[0033] The invention discloses a conveying and guiding device for wire feeding, which guides the conveying of wire feeding and effectively overcomes the problems of wire disorder and breakage during wire feeding. Meanwhile, the wire is straightened before wire feeding, which improves the stability and reliability of wire feeding and ensures safe production.

[0034] The present invention is not limited to the above-mentioned specific implementation modes, and various improvements made by those skilled in the art to the technical solutions according to the concept of the present invention shall all fall within the scope of protection claimed by the present invention.
