In the refining process, in order to improve the properties of metals, improve the processing performance, enhance the corrosion resistance or obtain special physical properties, it is usually necessary to add alloys or specific additives to the metal liquid.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0035] In order to facilitate understanding of the technical solutions of the present application, the reasons why the core wire is easily broken in the existing feeding machine are described as follows: the existing core wire is wound into a spiral shape and stacked, and the winding requirement for the core wire is high. If the winding process is disordered, or due to the large mass of the core wire, the bottom core wire is wound with each other due to gravity during the transfer process, the core wire is easily stuck, and the core wire is broken.

[0036] The present application provides a casting feeding machine, which can feed alloy or specific additives into molten metal, such as molten steel, through the core wire during the metal melting process. The use of the casting feeding machine can improve the absorption rate of the added substances, thereby improving the effect of melting.

[0037] As shown in FIG. 1, the feeding machine comprises a frame 100, a roller assembly 110, an unwinding assembly 200, a conveying assembly 300, a lifting module 340, a feeding pipe 400, and a feeding device 500. Figure 1 andFigure 2 As shown in the drawings, in one embodiment, the casting wire feeder 10 comprises a frame 100, a unwinding assembly 200, a conveying assembly 300 and a wire tube 400.

[0038] The unwinding assembly 200 comprises a unwinding shaft 210, the unwinding shaft 210 is rotatably arranged on the frame 100 around a first axis, and the unwinding shaft 210 can release the core wire 20 during rotation. The conveying assembly 300 is arranged on the frame 100 and arranged along a first direction perpendicular to the first axis with the unwinding shaft 210, and the conveying assembly 300 is used to convey the core wire 20 along the first direction. The wire tube 400 is arranged on the conveying assembly 300, and the conveying assembly 300 can convey the core wire 20 into the wire tube 400 and along the wire tube 400 to be conveyed into the metal liquid under the guidance of the wire tube 400.

[0039] By using the above-mentioned casting wire feeder 10, the core wire 20 is wound on the unwinding shaft 210, and the core wire 20 is released to the conveying assembly 300 during the rotation of the unwinding shaft 210, and the core wire 20 is input into the wire tube 400 by the conveying assembly 300 and enters the metal liquid under the guidance of the wire tube 400. Since the core wire 20 is wound on the unwinding shaft 210, and the core wire 20 can be released during the rotation of the unwinding shaft 210, and the conveying assembly 300 is located downstream of the rotation direction of the unwinding shaft 210, the release of the core wire 20 to the conveying assembly 300 can be more smooth, and the core wire 20 can be prevented from being stuck, thereby avoiding the core wire 20 from being broken.

[0040] It should be explained that the core wire 20 is wound on the unwinding shaft 210, and by arranging the unwinding shaft 210, the orderly winding of the core wire 20 can be more conveniently realized, and the release of the core wire 20 can be more smooth. The unwinding shaft 210 rotates around the first axis, so the rotation direction of the unwinding shaft is perpendicular to the first axis, and the conveying assembly 300 and the unwinding shaft 210 are arranged along the first direction perpendicular to the first axis, so it can be understood that the conveying assembly 300 is located downstream of the rotation direction of the unwinding shaft 210, at this time, the core wire 20 between the unwinding shaft 210 and the conveying assembly 300 will not appear excessive bending, thereby realizing that the core wire 20 on the unwinding shaft 210 is more smoothly conveyed to the conveying assembly 300.

[0041] Further, the unwinding shaft 210 is sleeved with a winding frame 220, the winding frame 220 is used to wind the core wire 20, and the winding frame 220 is in the shape of an I-beam, so as to further facilitate the winding of the core wire 20 and prevent the wound core wire 20 from being separated.

[0042] In one embodiment, the unwinding assembly 200 further comprises an unwinding drive connected with the unwinding shaft 210 to drive the unwinding shaft 210 to rotate, so as to realize automatic release of the core wire 20. Meanwhile, the unwinding drive can also realize tension control of the core wire 20 during unwinding. In this way, it can not only avoid excessive tension to break the core wire 20, but also avoid excessive accumulation of the core wire 20 between the unwinding assembly 200 and the conveying assembly 300.

[0043] In one embodiment, the casting wire feeder 10 further comprises a roller assembly 110 arranged at the bottom of the frame 100, so that the casting wire feeder 10 can be moved, further facilitating transportation of the casting wire feeder 10. Preferably, the roller assembly 110 comprises a plurality of universal wheels.

[0044] In one embodiment, the conveying assembly 300 is capable of rotating around a second axis, the wire feeding tube 400 is capable of rotating around a third axis parallel to the second axis, and both the conveying assembly 300 and the wire feeding tube 400 can pass through the working position during rotation.

[0045] When the conveying assembly 300 and the wire feeding tube 400 are both located at the working position, the core wire 20 in the conveying assembly 300 extends in a first direction, the wire feeding tube 400 is located downstream of the conveying assembly 300 in the first direction, and the discharge end of the conveying assembly 300 is in communication with the feeding end of the wire feeding tube 400, so that the conveying assembly 300 can input the core wire 20 into the wire feeding tube 400 and convey the core wire 20 along the wire feeding tube 400. Specifically to Figure 1 In the embodiment shown, the second axis and the third axis are both vertical axes, and the first direction is horizontal.

[0046] It should be explained that when the conveying assembly 300 and the wire feeding tube 400 are both located at the working position, the wire feeding tube 400 is located downstream of the conveying assembly 300 in the first direction, i.e., the conveying assembly 300 and the wire feeding tube 400 are arranged in sequence along the first direction, and the wire feeding tube 400 is located downstream of the conveying assembly 300 along the direction of conveying the core wire 20, so that the conveying assembly 300 can input the core wire 20 into the wire feeding tube 400.

[0047] In combination with Figure 1 It should be explained that, Figure 1When the casting wire feeder 10 is in the working state, the conveying assembly 300 and the wire feeder tube 400 are located at the working position, the pay-off assembly 200 releases the core wire 20 to the conveying assembly 300, the core wire 20 is input into the wire feeder tube 400 by the conveying assembly 300, and then is guided into the molten steel by the wire feeder tube 400. After the input of the core wire 20 is completed, the conveying assembly 300 and the wire feeder tube 400 can be rotated so that the conveying assembly 300 and the wire feeder tube 400 are arranged at an angle, the length of the conveying assembly 300 and the wire feeder tube 400 extending out of the rack 100 is reduced, and the volume of the casting wire feeder 10 is reduced, thereby facilitating the transportation and storage of the casting wire feeder 10.

[0048] In one embodiment, the conveying assembly 300 and the wire feeder tube 400 can pass through the storage position during the rotation, and the conveying assembly 300 and the wire feeder tube 400 are rotated between the working position and the storage position. As shown in Figure 2 , the conveying assembly 300 and the wire feeder tube 400 are located at the storage position.

[0049] When the conveying assembly 300 and the wire feeder tube 400 are located at the storage position, the core wire 20 in the conveying assembly 300 extends in a second direction which is at an angle to the first direction, and the plane in which the central axis of the wire feeder tube 400 is located is arranged at an angle to the second direction. By simultaneously storing the conveying assembly 300 and the wire feeder tube 400, the volume of the casting wire feeder 10 can be further reduced, thereby facilitating the transportation and storage of the casting wire feeder 10. In the embodiment shown in Figure 2 , the first direction and the second direction are perpendicular, and the first direction and the second direction are both horizontal directions, and the plane in which the central axis of the wire feeder tube 400 is located is perpendicular to the second direction.

[0050] As can be understood from Figure 1 and Figure 2 , the range of the conveying assembly 300 extending out of the rack 100 is small, so in other embodiments, the conveying assembly 300 can also be fixedly arranged on the rack 100, and the storage of the wire feeder tube 400 can be realized by rotating the wire feeder tube 400. Of course, the conveying assembly 300 is preferably rotatable, and the following will be described by taking the rotatable as an example.

[0051] It can be determined from Figure 1 and Figure 2 that the conveying assembly 300 and the wire feeder tube 400 rotate in the same direction from the working position to the storage position, so as to improve the storage effect. Assuming that the conveying assembly 300 is rotated clockwise from the working position to the storage position, the wire feeder tube 400 is also rotated clockwise from the working position to the storage position.

[0052] It is to be noted that the above-mentioned working position and storage position are described according to functions, and do not limit the delivery assembly 300 and the wire feeding tube 400 to be in the same position, but refer to that when in the working position, the delivery assembly 300 and / or the wire feeding tube 400 can perform the action of delivering the core wire 20; and when in the storage position, the delivery assembly 300 and / or the wire feeding tube 400 are retracted into the rack 100. In other words, the above-mentioned delivery assembly 300 rotates between the first working position and the first storage position, and the wire feeding tube 400 rotates between the second working position and the second storage position.

[0053] In addition, when the delivery assembly 300 is in the working position, the delivery assembly 300 starts to deliver the core wire 20; and when the delivery assembly 300 is in the storage position, the delivery assembly 300 does not deliver the core wire 20. Therefore, the delivery assembly 300 is used to deliver the core wire 20 in the first direction.

[0054] In an embodiment, the casting wire feeder 10 further comprises a first rotary driving member 510, which is arranged on the rack 100 and connected with the delivery assembly 300 to drive the delivery assembly 300 to rotate around the second axis. Specifically, the first rotary driving member 510 is an electric motor.

[0055] In an embodiment, the delivery assembly 300 can also fix the core wire 20, i.e. stop the delivery of the core wire 20, so that the core wire 20 is fixed relative to the rack 100. After the core wire 20 is fixed, the wire feeding tube 400 can be rotated around the third axis, so that the core wire 20 moves in and out of the wire feeding tube 400, thereby removing the metal slag at the discharge end of the wire feeding tube 400. It is to be noted that the discharge end of the wire feeding tube 400 is close to the molten steel, and the molten steel is easy to splash to the discharge end of the wire feeding tube 400 and solidify to form metal slag. If the metal slag accumulates too much, it will cause the wire feeding tube 400 to be blocked. Therefore, the core wire 20 moves in and out of the wire feeding tube 400, so that the metal slag at the discharge end of the wire feeding tube 400 is removed.

[0056] In an embodiment, the delivery assembly 300 comprises a mounting box 310, a delivery module 320 and a counting module 330, the mounting box 310 is rotatably connected to the rack 100 around the second axis, and the delivery module 320 and the counting module 330 are arranged in the mounting box 310. The delivery module 320 is used to deliver or fix the core wire 20, and the counting module 330 is used to measure the delivery length of the core wire 20. It can be determined that when the delivery assembly 300 is in the working position, the delivery module 320 and the counting module 330 are arranged in the first direction, so as to ensure that the core wire 20 in the delivery assembly 300 extends in the first direction. Specifically, to the embodiment shown in the figure, the delivery module 320 is arranged upstream of the counting module 330. Figure 3 In the embodiment shown in the figure, the counting module 330 is arranged downstream of the delivery module 320.

[0057] In one embodiment, the conveying module 320 comprises a conveying driving wheel 321, a conveying driven wheel 322 and a conveying driving member 323. The conveying driving wheel 321 and the conveying driven wheel 322 are rotatably arranged in the mounting box 310 and can cooperate to clamp the core wire 20. The conveying driving member 323 is arranged in the mounting box 310 and connected with the conveying driving wheel 321 to drive the conveying driving wheel 321 to rotate, so that the conveying driving wheel 321 and the conveying driven wheel 322 cooperate to convey the core wire 20.

[0058] Further, the conveying module 320 further comprises a pressing driving member 324 arranged in the mounting box 310 and connected with the conveying driven wheel 322 to drive the conveying driven wheel 322 to press the core wire 20 against the conveying driving wheel 321. It can be understood that the conveying driven wheel 322 is rotatably connected with the pressing driving member 324. Optionally, the pressing driving member 324 is a pneumatic cylinder or an oil cylinder.

[0059] In actual application, the circumferential side surface of the conveying driving wheel 321 and the conveying driven wheel 322 is an arc surface concave inward, and a plurality of anti-skid teeth are arranged on the arc surface in a circumferential direction. In this way, the core wire 20 can be prevented from slipping relative to the conveying module 320. At the same time, it can be determined that when the conveying driving member 323 stops driving the conveying driving wheel 321 to rotate, the conveying driving wheel 321 and the conveying driven wheel 322 can cooperate to clamp and fix the core wire 20.

[0060] Specifically Figure 3 In the embodiment shown, the conveying module 320 comprises two conveying driving wheels 321, two conveying driven wheels 322 and two pneumatic cylinders arranged one by one. The two conveying driving wheels 321 are arranged in sequence and spaced apart in the conveying direction of the core wire 20, and the conveying driving member 323 is connected with the two conveying driving wheels 321 at the same time. In this way, through the cooperation of the two conveying driving wheels 321 and the two conveying driven wheels 322, the stability of conveying can be further improved.

[0061] In one embodiment, the counting module 330 comprises a counting wheel 331, an auxiliary wheel 332 and an encoder 333. The counting wheel 331 and the auxiliary wheel 332 are rotatably arranged in the mounting box 310 and cooperate to clamp the core wire 20 to rotate during the conveying of the core wire 20. The encoder 333 is arranged on the counting wheel 331 to measure the conveying length of the core wire 20 during the rotation of the counting wheel 331. It should be noted that, in order to prevent the core wire 20 from slipping relative to the counting wheel 331 and the auxiliary wheel 332, the circumferential side surface of the counting wheel 331 and the auxiliary wheel 332 is also an arc surface concave inward, and the arc surface is also provided with anti-skid teeth.

[0062] In actual application, the counting module 330 further comprises a compression spring 334 arranged in the mounting box 310 and connected with the counting wheel 331 to drive the counting wheel 331 to move towards the auxiliary wheel 332, so as to compress the core wire 20 against the auxiliary wheel 332.

[0063] In one embodiment, both sides of the mounting box 310 are provided with through holes for the core wire 20 to pass through in the conveying direction of the core wire 20. Specifically, Figure 3 In the embodiment, the core wire 20 enters the mounting box 310 from the left through hole, then passes through the conveying module 320 and the counting module 330 in sequence, and is output from the right through hole.

[0064] Please refer to Figure 3 and Figure 4 In one embodiment, the conveying assembly 300 further comprises a lifting module 340 rotatably connected to the mounting box 310 around a fourth axis and located downstream of the conveying module 320. The lifting module 340 is provided with a feeding channel for the core wire 20 to pass through. The feeding tube 400 is connected to the lifting module 340, and the feeding end of the feeding tube 400 is in communication with the feeding channel, so that the core wire 20 can be input into the feeding tube 400 through the feeding channel.

[0065] The lifting module 340 can pass through a feeding position and a lifting position during rotation. When the lifting module 340 is located at the feeding position, the extension direction of the feeding channel is the same as the extension direction of the core wire 20 at the conveying module 320, so that the core wire 20 conveyed by the conveying module 320 can pass through the feeding channel; when the lifting module 340 is located at the lifting position, the extension direction of the feeding channel is arranged at an angle with the extension direction of the core wire 20 at the conveying module 320, so that the path of the core wire 20 is extended. In combination with the above-mentioned scheme of fixing the core wire 20 by the conveying module 320, this operation can make the core wire 20 extend and retract in the feeding tube 400, and remove the metal slag at the discharge end of the feeding tube 400.

[0066] It can be understood that when the lifting module 340 needs to be rotated from the feeding position to the lifting position, the conveying module 320 needs to stop conveying the core wire 20, i.e. the core wire 20 is clamped and fixed. Therefore, by reciprocating the lifting module 340 between the feeding position and the lifting position, the core wire 20 can be made to extend and retract in the feeding tube 400, and the metal slag at the discharge end of the feeding tube 400 can be removed.

[0067] Optionally, the lifting module 340 rotates from the feeding position to the lifting position, and the feeding tube 400 is lifted by 0.2-0.3 m away from one end of the conveying assembly 300, so as to ensure that the core wire 20 can be completely retracted into the feeding tube 400 when the lifting module 340 rotates to the lifting position, thereby ensuring that the metal slag at the discharge end of the feeding tube 400 can be removed when the core wire 20 extends and retracts in the feeding tube 400. Preferably, the lifting module 340 rotates from the feeding position to the lifting position, and the feeding tube 400 is lifted by 0.25 m away from one end of the conveying assembly 300.

[0068] Specifically, the feeding tube 400 is rotatably connected to the lifting module 340 around the third axis. As shown in FIGS. 1, 2 and 3, when the conveying assembly 300 and the feeding tube 400 are in the working position, the lifting module 340 is in the lifting position. Similarly, it can be known that in the embodiments shown in FIGS. 4 and 5, the lifting module 340 is in the feeding position. Figure 4 Figure 1 Figure 2

[0069] When the lifting module 340 is in the feeding position and the conveying assembly 300 is in the working position, the feeding channel extends in the first direction, that is, the extension direction of the feeding channel is the same as the extension direction of the core wire 20 at the conveying module 320; when the feeding tube 400 is in the working position, the feeding channel is in communication with the feeding end of the feeding tube 400, so that the core wire 20 passing through the feeding channel enters the feeding tube 400, facilitating the conveying of the core wire 20. The fourth axis is perpendicular to the extension direction of the core wire 20 in the mounting box 310, and the fourth axis is also perpendicular to the second axis.

[0070] It should be noted that the reciprocating lifting of the core wire 20 close to the molten steel end is realized by the rotation of the lifting module 340, and this operation can be matched with the rotation of the feeding tube 400 in the above-mentioned embodiments to prolong the stroke of the extension and retraction of the core wire 20. Of course, in other embodiments, the rotation of the feeding tube 400 can also be used for switching between the working position and the storage position, and the removal of the metal slag at the discharge end of the feeding tube 400 can be realized by the action of the lifting module 340.

[0071] By using the above-described casting wire feeder 10, the core wire 20 prepared from the alloy or additive is released by the unwinding assembly 200, the core wire 20 is conveyed by the conveying assembly 300 at a speed of 0.1-0.8 m / s, and the core wire 20 is conveyed along the feeding tube 400 into the molten metal to realize the addition of the alloy or additive. In this way, the addition efficiency of the alloy or additive can be ensured, and the absorption rate of the molten metal to the alloy or additive is high, thereby improving the smelting effect.

[0072] ​​​It needs to be explained that the core wire 20 is input at a speed of 0.1-0.8 m / s, which can make the core wire 20 fully contact and react with the metal liquid, so as to improve the absorption rate of the metal liquid to the alloy or additive. Further, the outer diameter of the core wire is designed to be 9-16 mm, and the metal skin thickness of the core wire is 0.4-0.6 mm, and the feeding speed of 0.1-0.8 m / s can further improve the adding efficiency of the alloy or additive, and also can make the absorption rate of the metal liquid to the alloy or additive higher, and improve the smelting effect. For example, the feeding speed is 0.5 m / s, the diameter of the core wire is 13 mm, and the thickness of the metal skin is 0.45 mm, and the smelting effect is very excellent.

[0073] Please refer to Figure 3 to Figure 5 In an embodiment, the lifting module 340 comprises a mounting plate 341 and a guide pipe 342, the mounting plate 341 is rotatably connected to the side of the mounting box 310 away from the unwinding assembly 200 around the fourth axis, and the guide pipe 342 is arranged on the mounting plate 341, and the feeding pipe 400 is rotatably connected to the mounting plate 341 around the third axis. The guide pipe 342 has the feeding channel described above. When the lifting module 340 is located at the feeding position, the guide pipe 342 is coaxial with the through hole on the mounting box 310, so that the core wire 20 output by the through hole enters the guide pipe 342.

[0074] Further, the conveying assembly 300 further comprises a lifting driving member 350, which is arranged on the mounting box 310 and connected with the mounting plate 341 to drive the mounting plate 341 to rotate around the fourth axis. Specifically to Figure 3 In the embodiment shown, the lifting driving member 350 is a pneumatic cylinder arranged at the bottom of the mounting box 310, and the driving end of the lifting driving member 350 is hinged to the mounting plate 341.

[0075] Please refer to Figure 1 In an embodiment, the feeding pipe 400 comprises a feeding section 410, an intermediate section 420 and a discharging section 430 connected in sequence, the feeding section 410 is rotatably connected to the conveying assembly 300 around the third axis, and the intermediate section 420 is connected to the end of the feeding section 410 away from the conveying assembly 300. When the conveying assembly 300 and the feeding pipe 400 are both located at the working position, the feeding section 410 extends along the first direction, and the feeding section 410 is in communication with the guide pipe 342 to receive the core wire 20 output by the guide pipe 342; the discharging section 430 extends along the vertical direction to guide the core wire 20 to be conveyed along the vertical direction into the molten steel. In actual application, the intermediate section 420 is arc-shaped to make the conveying of the core wire 20 in the feeding pipe 400 more smooth.

[0076] It needs to be explained that, as can be known from the above embodiment, in Figure 4In the shown embodiment, the lifting module 340 is in the lifting position, and the discharge section 430 of the feeding tube 400 is inclined relative to the vertical direction. However, in actual operation, the lifting module 340 is used to realize the reciprocating movement of the core wire 20 in the feeding tube 400 to remove the metal slag at the discharge end, that is, when the lifting module 340 is in the lifting position, the conveying assembly 300 is in a special state, and when the lifting module 340 is in the feeding position, the conveying assembly 300 is in a normal state. In Figure 1 and Figure 2 In the shown embodiment, the conveying assembly 300 is in the normal state, and at this time, the discharge section 430 extends along the vertical direction, so it can be determined that the discharge section 430 is used to guide the core wire 20 to be conveyed along the vertical direction.

[0077] In one embodiment, the rotation radius of the feeding tube 400 is 0.2-0.4 m. It can be understood that, as Figure 5 shown, the feeding tube 400 is in the storage position, the angle between the central axis of the feeding tube 400 and the core wire 20 in the conveying assembly 300 is 90°, the core wire 20 extends from the conveying assembly 300 to the feeding tube 400, and the extension path of the core wire 20 is close to the rotation path of the feeding end of the feeding tube 400. Therefore, by increasing the rotation radius of the feeding tube 400, the curvature of the rotation path of the feeding end of the feeding tube 400 can be reduced, that is, the curvature of the core wire 20 between the conveying assembly 300 and the feeding tube 400 can be reduced, the bending degree of the core wire 20 can be reduced, and the core wire 20 can be prevented from being broken.

[0078] It should be noted that the conveying assembly 300 is rotatably connected to the rack 100, and in the process of rotating the conveying assembly 300 to the storage position, since the length of the core wire 20 between the unwinding assembly 200 and the conveying assembly 300 is relatively long, the activity range of the core wire 20 is relatively large, and the curvature of the core wire 20 can be adaptively adjusted, so that the core wire 20 between the unwinding assembly 200 and the conveying assembly 300 can be prevented from being broken.

[0079] Please also refer to Figure 6 In one embodiment, the casting wire feeder 10 further comprises a second rotary driving member 520, which is arranged on the conveying assembly 300 and specifically arranged on the mounting plate 341. The second rotary driving member 520 is connected with the feeding tube 400 to drive the feeding tube 400 to rotate around the third axis.

[0080] Further, the casting wire feeder 10 further comprises a connecting block 530, which is rotatably connected to the mounting plate 341 around the third axis. The feeding tube 400 is fixedly connected with the connecting block 530, so as to increase the rotation radius of the feeding tube 400.

[0081] Further, the casting wire feeder 10 further comprises a connecting gear 540 and a connecting rack 550. The connecting gear 540 is fixedly connected with the connecting block 530, and the connecting rack 550 is engaged with the connecting gear 540. The second rotary driving member 520 is connected with the connecting rack 550 to drive the connecting rack 550 to move back and forth, thereby driving the connecting gear 540 and the connecting block 530 to rotate around the third axis.

[0082] It can be understood that, in the embodiment, the second rotary driving member 520 is an electric cylinder, a pneumatic cylinder or an oil cylinder. In other embodiments, the second rotary driving member 520 can also be a motor, and in this case, the second rotary driving member 520 is directly connected with the connecting block 530 to drive the connecting block 530 to rotate around the second axis.

[0083] In order to facilitate the understanding of the technical solutions of the present application, the working process of the casting wire feeder 10 in the above embodiment will be described herein with reference to the accompanying drawings. Figure 1 Figure 2 Figure 4

[0084] Initially, the conveying assembly 300 and the wire feeding tube 400 in the casting wire feeder 10 are located at the storage position, and the core wire 20 on the unwinding assembly 200 has passed through the conveying assembly 300 and entered the wire feeding tube 400.

[0085] The casting wire feeder 10 is moved to a preset working position, and then the first rotary driving member 510 and the second rotary driving member 520 drive the conveying assembly 300 and the wire feeding tube 400 to rotate to the working position, respectively, so that the discharge end of the wire feeding tube 400 is close to the molten steel. Next, the unwinding driving member is actuated to release the core wire 20 under the condition of maintaining a certain tension. At the same time, the conveying module 320 continuously inputs the core wire 20 into the wire feeding tube 400, and the core wire 20 is input into the molten steel through the wire feeding tube 400. The counting module 330 measures the conveying length of the core wire 20 during the conveying process, thereby obtaining the wire feeding amount of the core wire 20. After the wire feeding amount reaches the requirement, the unwinding assembly 200 and the conveying assembly 300 stop the conveying of the core wire 20, and then the first rotary driving member 510 and the second rotary driving member 520 drive the conveying assembly 300 and the wire feeding tube 400 to rotate to the storage position, respectively.

[0086] It should be noted that, after the wire feeding is completed, the lifting module 340 can be driven by the lifting driving member 350 to reciprocate between the feeding position and the lifting position, so as to remove the metal slag at the discharge end of the wire feeding tube 400. In addition, a control box with a display screen can be arranged on the rack 100, and control parameters are input through the control box to control the action of the casting wire feeder 10.

[0087] In summary, the casting wire feeder 10 provided by the present application has at least the following advantages:

[0088] ​​​1. The conveying component 300 and the wire feeding tube 400 can be stored, which can effectively reduce the volume of the casting wire feeder 10, thereby facilitating the transportation, use and storage of the casting wire feeder 10;

[0089] 2. By actively unwinding the core wire 20 in conjunction with the unwinding drive and the unwinding shaft 210, the core wire 20 can be conveyed with stable tension.

[0090] 3. Using an I-shaped winding frame 220 to rotate and release the core wire 20 can make the release of the core wire 20 smoother and avoid jamming;

[0091] 4. The large rotation radius of the feed tube 400 can prevent the core wire 20 from being broken during the rotation of the feed tube 400.

[0092] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
