Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical equipment, and in particular to a wire feeding device. Background Technology

[0002] In the steelmaking process, wire feeding involves injecting cored wire or aluminum wire into molten steel to deoxidize, desulfurize, fine-tune the composition, clean the molten steel, and improve the morphology of non-metallic inclusions. As a derivative device of the wire feeding process, the wire feeder can control the wire feeding amount and speed, ensuring the yield of alloy components. Therefore, the continuous and stable operation of the wire feeder directly affects the quality of the molten steel and the cast billet.

[0003] The wire feeding devices designed in related technologies mostly adopt a single set of wire feeding wheels structure. The single set of wire feeding wheels structure consists of only one driving wheel and one driven wheel. The driving wheel is driven by a motor to move the alloy cored wire. However, its wire feeding stability is poor and it is prone to slippage or bending. Therefore, it needs to be improved. Utility Model Content

[0004] In order to effectively prevent bending of alloy cored wire during the conveying process, ensure uniform wire feeding speed, and improve the accuracy of alloy addition, this application provides a wire feeding device.

[0005] The wire feeding device provided in this application adopts the following technical solution: A wire feeding device includes a housing with a wire roller rotatably mounted on it. A wire inlet is provided on the surface of the housing. A set of wire feeding assemblies are symmetrically arranged inside the housing, with guide tubes connecting the wire feeding assemblies to the inner wall of the housing. Each wire feeding assembly includes a driving wheel and a driven wheel. A driving gear is coaxially fixed to the end wall of the driving wheel, and a driven gear is coaxially fixed to the end wall of the driven wheel. The driven gear meshes with the driving gear. A rotating assembly is provided inside the housing to drive one of the driving gears to rotate. A synchronous pulley is coaxially fixed to the end of the driven wheel away from the driven gear, and a synchronous belt is tensioned and fitted onto the synchronous pulley.

[0006] By adopting the above technical solution, the alloy cored wire is wound on a wire roller. The alloy cored wire extends from the wire roller, first passing through the inlet, and then through a guide tube between the wire feeding components. The driving gear is driven by the rotating component to rotate, and the driving gear abuts against the driven gear, thereby driving the driving wheel and the driven wheel to rotate in opposite directions. The driving wheel and the driven wheel simultaneously abut against the surface of the alloy cored wire, using friction to give the alloy cored wire power, continuously drawing it out from the wire roller. After passing through one wire feeding component, the alloy cored wire passes through another guide tube to reach another wire feeding component. The two wire feeding components are symmetrically arranged, and the two driven wheels rotate synchronously through a synchronous belt. Finally, the alloy cored wire is transported to the depth of the molten iron ladle through the guide tube below the wire feeding component, completing the wire feeding operation. The two wire feeding components and multiple guide tubes make the alloy cored wire transportation stable and controllable. The meshing of the driving gear and the driven gear ensures that the driving wheel and the driven wheel rotate synchronously, effectively preventing the alloy cored wire from bending during transportation, ensuring uniform wire feeding speed, and improving the accuracy of alloy addition.

[0007] Preferably, a connecting frame is provided between the driven wheels, the driven wheels are rotatably mounted on the side wall of the connecting frame, the connecting frame is slidably connected to the housing, and a sliding assembly for driving the connecting frame to slide is provided inside the housing.

[0008] Preferably, the sliding assembly includes a lead screw slide rail and a first slider. The lead screw slide rail is fixedly mounted on the inner wall of the housing, and the first slider is slidably mounted on the lead screw slide rail. The connecting frame and the first slider are fixed to each other.

[0009] By adopting the above technical solution, when the lead screw slide rail is working, it can drive the first slider to slide on the lead screw slide rail, control the sliding of the connecting frame connected to the first slider, drive the driven wheel to move closer to or away from the driving wheel, adjust the distance between the driving wheel and the driven wheel, and thus adjust the force on the alloy cored wire during wire feeding to meet different wire feeding requirements and improve the applicability of the device.

[0010] Preferably, the rotating assembly includes a guide rail, a second slider, a motor, a circular gear, a sector gear, and a sliding member. The guide rail is fixedly installed inside the housing, the second slider is slidably installed on the guide rail, the motor is fixedly installed on the second slider, the drive shaft of the motor is connected to the circular gear and the sector gear, the sector gear and the circular gear are coaxially arranged and their teeth are aligned with each other, both the sector gear and the circular gear can mesh with the drive gear, and the sliding member is used to drive the second slider to slide on the guide rail.

[0011] Preferably, the sliding component is a cylinder, which is fixedly mounted on the slide rail, and the piston rod of the cylinder is connected to the motor.

[0012] By adopting the above technical solution, when the circular gear and the driving gear mesh, the motor drives the circular gear to rotate, and the circular gear abuts against the driving gear, thereby driving the driving gear to rotate. When gap feeding is required, the sliding component drives the second slider to slide on the guide rail, thereby driving the motor to slide. At this time, the circular gear and the driving gear disengage. However, since the sector gear and the circular gear are aligned with each other, the sector gear and the driving gear will mesh after the cylinder works. The motor drives the sector gear to rotate continuously, controlling the drive gear to rotate intermittently, thereby realizing gap feeding. Thus, when the motor is working continuously, the device can quickly switch between continuous feeding and gap feeding, thereby meeting different processing requirements and further expanding the applicability of the device.

[0013] Preferably, a key block is integrally provided on the drive shaft of the motor, and the circular gear and the sector gear are connected to the drive shaft of the motor via the key block. A positioning block is fixedly provided on the drive shaft of the motor, and a positioning nut is also threadedly connected to the drive shaft of the motor. The positioning block abuts against the circular gear, and the positioning nut abuts against the sector gear.

[0014] By adopting the above technical solution, rotating the positioning nut disengages it from the motor drive shaft, allowing the circular gear and sector gear to be removed from the motor drive shaft. This facilitates the assembly of the circular gear and sector gear. The key block connection effectively prevents slippage. At the same time, different sector gears can be replaced, and the length of the gap feed can be controlled to meet different processing requirements.

[0015] Preferably, the bottom of the box is provided with a positioning frame and a first support frame, and two of each are symmetrically arranged. The first support frame is fixed to the box, the top of the positioning frame is hinged to the box, and a set of second support frames is fixedly provided on the side wall of the box.

[0016] By adopting the above technical solution, the angle of the box can be changed by rotating the box and positioning frame and using the second support frame to abut against the ground, thus realizing both horizontal and vertical wire feeding functions, thereby further improving the applicability of the device.

[0017] Preferably, the bottom end of the positioning frame is fixed to the ground, and the bottom ends of the first support frame and the second support frame are fixedly provided with expansion panels.

[0018] By adopting the above technical solution, after changing the wire feeding direction of the device, it is beneficial to the overall stability of the box and reduces the phenomenon of device shaking.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a housing, wire rollers, wire inlet, wire feeding assembly, guide tube, driving wheel, driven wheel, driving gear, driven gear, rotating assembly, synchronous wheel and synchronous belt, the two wire feeding assemblies and the multi-segment guide tube make the alloy cored wire feeding stable and controllable. The meshing of the driving gear and driven gear ensures that the driving wheel and driven wheel rotate synchronously, effectively preventing the alloy cored wire from bending during the feeding process, ensuring uniform wire feeding speed, and improving the accuracy of alloy addition; 2. By setting up guide rails, a second slider, a motor, a circular gear, a sector gear, and sliding parts, the device can quickly switch between continuous wire feeding and intermittent wire feeding while the motor is working continuously, thereby enabling the device to meet different processing requirements and further expanding the applicability of the device; 3. By setting up a positioning frame, a first support frame, and a second support frame, the box body can be rotated relative to the positioning frame. By using the second support frame to abut against the ground, the angle of the box body can be changed, realizing both horizontal and vertical wire feeding functions, thereby further improving the applicability of the device.

[0023] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0024] This application discloses a wire feeding device. (Refer to...) Figure 1The device includes a housing 1, on which a wire roller 12 is rotatably mounted. The wire roller 12 is wound with an alloy cored wire to be processed. An inlet 11 is provided on the surface of the housing 1. A set of wire feeding assemblies is symmetrically arranged inside the housing 1, and guide tubes 2 are provided between the wire feeding assemblies. Several guide tubes 2 can be provided inside the housing 1, and the guide tubes 2 are interconnected with the inner wall of the housing 1. The alloy cored wire is wound onto the wire roller 12, extends from the wire roller 12, first passes through the inlet 11, and then passes through a section of guide tube 2 between the wire feeding assemblies.

[0025] Reference Figure 1 The wire feeding assembly includes a driving wheel 31 and a driven wheel 32 that are parallel to each other. A driving gear 311 is coaxially fixed to the end wall of the driving wheel 31, and a driven gear 321 is coaxially fixed to the end wall of the driven wheel 32. A rotating assembly for driving one of the driving gears 311 to rotate is provided inside the housing 1. A synchronous wheel 4 is coaxially fixed to the end of the driven wheel 32 away from the driven gear 321, and a synchronous belt 41 is tensioned and sleeved on the synchronous wheel 4. The driving gear 311 is driven to rotate by the rotating assembly. The driving gear 311 abuts against the driven gear 321, which in turn drives the driving wheel 31 and the driven wheel 32 to rotate in opposite directions. The driving wheel 31 and the driven wheel 32 simultaneously abut against the surface of the alloy cored wire, using friction to give the alloy cored wire power. The alloy cored wire is continuously drawn out from the wire roller 12. After passing through a wire feeding assembly, the alloy cored wire passes through a guide tube 2 to reach another wire feeding assembly. The two wire feeding assemblies are symmetrically arranged, and the two driven wheels 32 rotate synchronously through a synchronous belt 41. Finally, the alloy cored wire is transported to the depth of the molten iron ladle through the wire tube below the wire feeding assembly, completing the wire feeding operation.

[0026] Reference Figure 1A connecting frame 5 is provided between the driven wheels 32. The driven wheels 32 are rotatably mounted on the side wall of the connecting frame 5. The connecting frame 5 is slidably connected to the housing 1. A sliding assembly for driving the sliding of the connecting frame 5 is provided inside the housing 1. The sliding assembly includes a lead screw slide rail 51 and a first slider 52. The lead screw slide rail 51 is fixedly mounted on the inner wall of the housing 1. The length direction of the lead screw slide rail 51 is perpendicular to the length direction of the driven wheels 32. The first slider 52 is slidably mounted on the lead screw slide rail 51. The connecting frame 5 and the first slider 52 are fixed to each other. When the lead screw slide rail 51 is working, it can drive the first slider 52 to slide on the lead screw slide rail 51, control the sliding of the connecting frame 5 connected to the first slider 52, drive the driven wheels 32 to move closer to or away from the driving wheels 31, adjust the distance between the driving wheels 31 and the driven wheels 32, and thus adjust the force on the alloy cored wire during wire feeding to meet different wire feeding requirements and improve the applicability of the device. It should be noted that the lead screw slide rail 51 only makes minor adjustments to the position of the driven wheel 32. After the driven wheel 32 moves, the driven gear 321 can still mesh with the driving gear 311, maintaining the original functions of the driven gear 321 and the driving gear 311.

[0027] Reference Figure 1 and Figure 2 The rotating assembly includes a guide rail 61, a second slider 62, a motor 63, a circular gear 64, a sector gear 65, and a sliding component. The guide rail 61 is fixedly installed inside the housing 1, and its length direction is parallel to the length direction of the drive wheel 31. The second slider 62 is slidably installed on the guide rail 61. The motor 63 is fixedly installed on the second slider 62 by bolts. The drive shaft of the motor 63 is connected to the circular gear 64 and the sector gear 65. The sector gear 65 and the circular gear 64 are coaxially arranged and their teeth are aligned. Both the sector gear 65 and the circular gear 64 can mesh with the drive gear 311. The sliding component is a cylinder 7, which is fixedly installed on the slide rail by bolts. The piston rod of the cylinder 7 is connected to the motor 63. When the circular gear 64 meshes with the driving gear 311, the motor 63 drives the circular gear 64 to rotate, and the circular gear 64 abuts against the driving gear 311, thereby driving the driving wheel 31 to rotate. When intermittent wire feeding is required, the sliding component drives the second slider 62 to slide on the guide rail 61, thereby driving the motor 63 to slide. At this time, the circular gear 64 and the driving gear 311 disengage. However, since the sector gear 65 is aligned with the circular gear 64, the sector gear 65 will mesh with the driving gear 311 after the cylinder 7 is working. The motor 63 drives the sector gear 65 to rotate continuously, controlling the driving gear 311 to rotate intermittently, thereby realizing intermittent wire feeding. Thus, when the motor 63 is working continuously, the device can quickly switch between continuous wire feeding and intermittent wire feeding, enabling the device to meet different processing requirements and further expanding the applicability of the device.

[0028] Reference Figure 2 A key block 8 is integrally mounted on the drive shaft of motor 63, with its length aligned with the length of the drive shaft. Circular gear 64 and sector gear 65 are connected to the drive shaft of motor 63 via the key block 8. A positioning block 81 is fixedly mounted on the drive shaft of motor 63, and a positioning nut 82 is fitted onto the end of the drive shaft. The positioning block 81 abuts against the circular gear 64, and the positioning nut 82 abuts against the sector gear 65. Rotating the positioning nut 82 disengages it from the drive shaft of motor 63, allowing the circular gear 64 and sector gear 65 to be removed for easy assembly. The keyed connection via the key block 8 effectively prevents slippage and allows for the replacement of different sector gears 65, controlling the wire feeding length to meet various processing requirements.

[0029] Reference Figure 1 The bottom of the housing 1 is provided with a positioning frame 9 and a first support frame 91. Two positioning frames 9 and two first support frames 91 are symmetrically arranged. The first support frame 91 is fixed to the housing 1, the bottom of the positioning frame 9 is fixed to the ground, and the top of the positioning frame 9 is hinged to the housing 1. A set of second support frames 92 is welded and fixed to the side wall of the housing 1. The length of the second support frame 92 is the same as the length of the first support frame 91, and the length direction of the second support frame 92 is perpendicular to the length direction of the first support frame 91. An expansion panel 10 is fixed to the bottom of the first support frame 91 and the second support frame 92. When the first support frame 91 is in contact with the ground, the device can achieve vertical wire feeding. By rotating the housing 1 and the positioning frame 9, and using the second support frame 92 to contact with the ground, the angle of the housing 1 can be changed, achieving horizontal wire feeding, thereby further improving the applicability of the device.

[0030] The implementation principle of a wire feeding device according to an embodiment of this application is as follows: Alloy cored wire is wound onto a wire roller 12. The alloy cored wire extends from the wire roller 12, first passing through the wire inlet 11, then through a guide tube 2 between the wire feeding components. The driving gear 311 is driven to rotate by the rotating component, and the driving gear 311 abuts against the driven gear 321, thereby driving the driving wheel 31 and the driven wheel 32 to rotate in opposite directions. The driving wheel 31 and the driven wheel 32 simultaneously abut against the surface of the alloy cored wire, using friction to give the alloy cored wire power, causing the alloy cored wire to continuously be drawn out from the wire roller 12; the alloy cored wire passes through... After passing through a guide tube 2, the wire feeder reaches another wire feeder. The two wire feeder components are symmetrically arranged, and the two driven wheels 32 rotate synchronously through a synchronous belt 41. Finally, the wire feeder passes through the guide tube below the wire feeder to transport the alloy cored wire deep into the molten iron ladle, completing the wire feeding operation. The two wire feeder components and the multiple guide tubes 2 ensure stable and controllable feeding of the alloy cored wire. The meshing of the drive gear 311 and the driven gear 321 ensures that the drive wheel 31 and the driven wheel 32 rotate synchronously, effectively preventing bending of the alloy cored wire during the feeding process, ensuring uniform wire feeding speed, and improving the accuracy of alloy addition.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
