Description

Technical Field

[0001] This utility model relates to the field of steelmaking equipment technology, and in particular to a multi-directional adjustable wire feeder. Background Technology

[0002] Wire feeders are key equipment in steelmaking for the precise addition of wire materials such as alloys, deoxidizers, and spheroidizing agents. Driven by a motor, rollers clamp metal-cored or solid wires and feed them into molten steel or iron at a set speed and length to improve the efficiency of metallurgical reactions and the precision of composition control. In the calcium treatment process of aluminum-containing steel, calcium wire needs to be evenly distributed in the molten steel to achieve efficient deoxidation and inclusion modification. Traditional wire feeders only have the vertical lifting function of the feeding tube, which limits the distribution range of calcium wire in the ladle, easily causing localized calcium accumulation or unreacted areas, resulting in low calcium absorption (usually less than 15%).

[0003] Utility model patent CN218015657U discloses a safe wire feeding machine for cast alloy materials. It includes a support base with an inverted "T" shaped vertical cross-section. A turntable is rotatably connected to the outer side of the support base. The top of the turntable is fixedly connected to the main body of the wire feeding machine. A gear ring is fixedly connected to the outer side of the turntable, and a gear is meshed with the outer side of the gear ring. The gear is fixed to the outer side of the output shaft of a motor. The motor drives the gear and turntable to rotate, adjusting the lateral circumferential angle of the wire feeding machine and changing the position of the wire outlet end of the guide tube in the horizontal direction. An electric telescopic rod is hinged to one side wall of the main body of the wire feeding machine. Activating the electric telescopic rod, in conjunction with the base plate, allows adjustment of the guide tube angle to meet wire feeding requirements at different angles. However, the above device cannot adjust the length of the guide tube, resulting in a limited feeding area. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a wire feeder with a compact structure and multi-directional adjustable wire feeding position, which improves the uniformity of core wire distribution in molten steel and enhances core wire absorption rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-directional adjustable wire feeder includes an equipment box, a wire feed tube, and a guide device located between the two. The guide device includes a telescopic mechanism, a horizontal mechanism, and a lifting mechanism for adjusting the wire feeding position of the wire feed tube. The telescopic mechanism includes a first guide cylinder, a second guide cylinder, and a third guide cylinder arranged sequentially from the inside out. The third guide cylinder is a fixed end, and the first and second guide cylinders are movable ends. An electric push rod is mounted on the upper part of the third guide cylinder, and the output end of the electric push rod is fixedly connected to the second guide cylinder. Movable gears are mounted on both side walls of the second guide cylinder. Racks are fixedly connected to the inner side wall of the third guide cylinder and the outer side wall of the first guide cylinder. The movable gears mesh with the racks. The top of the first guide cylinder is connected to the wire feed tube.

[0007] The telescopic mechanism of the aforementioned multi-directional adjustable wire feeder further includes a first guide tube, a second guide tube, and a third guide tube located inside the first guide cylinder, the second guide cylinder, and the third guide cylinder.

[0008] In the aforementioned multi-directional adjustable wire feeder, the first guide tube is fixedly connected to a first limiting ring at one end inside the second guide tube, and the third guide tube is fixedly connected to a third limiting ring at one end outside the second guide tube. The two ends of the second guide tube are respectively provided with a second inner limiting ring and a second outer limiting ring. The first limiting ring and the second inner limiting ring cooperate to limit the extension position of the first guide tube, and the third limiting ring and the second outer limiting ring cooperate to limit the extension position of the second guide tube.

[0009] In the aforementioned multi-directional adjustable wire feeder, the wire feed tube is threadedly connected to the first guide cylinder.

[0010] In the aforementioned multi-directional adjustable wire feeder, guide bars are provided on both the upper and lower sides of the second and third guide cylinders, and the first and second guide cylinders slide between the two guide bars respectively.

[0011] In the aforementioned multi-directional adjustable wire feeder, the telescopic mechanism is fixed on a horizontal mechanism. The horizontal mechanism includes a support plate located on one side of the wire outlet of the equipment box. A drive wheel and a driven wheel are rotatably connected to the center of the bottom of the support plate. A rotating motor is mounted on one side of the support plate via a bracket. The output end of the rotating motor is connected to the drive wheel. The drive wheel and the driven wheel rotate along the groove of the track. The track is fixed on a track bracket.

[0012] The aforementioned multi-directional adjustable wire feeder has a corrugated pipe at the outlet of the equipment box. The corrugated pipe passes through the support plate and connects to the third guide cylinder of the telescopic mechanism. The groove of the track is arc-shaped.

[0013] The aforementioned multi-directional adjustable wire feeder includes a lifting hydraulic cylinder as its lifting mechanism. The lifting hydraulic cylinder is hinged to a hydraulic cylinder base, which is fixed to one side of a support plate. The support plate is also fixedly connected to a guide cylinder base, which is hinged to a third guide cylinder. The bottom of the third guide cylinder is hinged to the output end of the lifting hydraulic cylinder.

[0014] The beneficial effects of adopting the above technical solution are as follows:

The feeding tube is fixed on the first guide cylinder, and the first and second guide cylinders are moved back and forth by an electric push rod and a moving gear, thereby realizing the radial movement of the feeding tube along the ladle. In addition, a third guide cylinder is fixed on a support plate, and a rotating motor and a drive wheel are assembled at the bottom of the support plate. The rotating motor drives the drive wheel to move along the track, realizing the lateral translation of the feeding tube. In the longitudinal direction, the third guide cylinder and the lifting hydraulic cylinder are respectively hinged to the support plate.

[0022] like Figure 1-4 As shown, this utility model includes an equipment box 1, a wire feeding tube 2, and a guide device located between the two. The guide device includes a telescopic mechanism 3, a horizontal mechanism 4, and a lifting mechanism 5, used to adjust the wire feeding position of the wire feeding tube 2. The telescopic mechanism 3 includes a first guide cylinder 31, a second guide cylinder 32, and a third guide cylinder 33 arranged sequentially from the inside to the outside. The third guide cylinder 33 is a fixed end, and the first guide cylinder 31 and the second guide cylinder 32 are movable ends. An electric push rod 34 is mounted on the upper part of the third guide cylinder 33. The output end of the electric push rod 34 is connected to... The second guide cylinder 32 is fixedly connected, and both sides of the second guide cylinder 32 are equipped with moving gears 321. The inner side wall of the third guide cylinder 33 and the outer side wall of the first guide cylinder 31 are both fixedly connected with racks 311. The moving gears 321 mesh with the racks 311. The top end of the first guide cylinder 31 is connected to the wire feeding tube 2. The second guide cylinder 32 is moved by the electric push rod 34. Then the moving gears 321 on the second guide cylinder 32 move along the racks 311, and at the same time drive the first guide cylinder 31 to move, thereby realizing the forward and backward extension and retraction of the wire feeding tube 2.

[0023] like Figure 2 , 3As shown, the telescopic mechanism 3 also includes a first guide tube 35, a second guide tube 36, and a third guide tube 37 located inside the first guide tube 31, the second guide tube 32, and the third guide tube 33. The first guide tube 35 is fixedly connected to one end of the first guide tube 31 and the wire feeding tube 2, and the other end is sleeved inside the second guide tube 36. The other end of the second guide tube 36 is sleeved inside the third guide tube 37. The other end of the third guide tube 37 is fixedly connected to one end of the third guide tube 33 and the equipment box 1. The core wire enters the telescopic mechanism 3 from the outlet of the equipment box 1, passes through the first guide tube 35, the second guide tube 36, and the third guide tube 37, and then enters the wire feeding tube 2. Then, it enters the molten steel in the ladle from the opening of the wire feeding tube 2. The three guide tubes connected in sequence provide a passage for the core wire to pass through the telescopic mechanism 3, and the three guide tubes extend and retract synchronously with the guide tubes to ensure the continuity of the passage.

[0024] To prevent the first guide tube 35 and the second guide tube 36 from slipping during extension, limiting rings are provided on each guide tube. The first guide tube 35 is fixedly connected to the first limiting ring 351 at one end inside the second guide tube 36, and the third guide tube 37 is fixedly connected to the third limiting ring 371 at one end outside the second guide tube 36. The two ends of the second guide tube 36 are respectively provided with a second inner limiting ring 361 and a second outer limiting ring 362. The first limiting ring 351 and the second inner limiting ring 361 cooperate to limit the extension position of the first guide tube 35, and the third limiting ring 371 and the second outer limiting ring 362 cooperate to limit the extension position of the second guide tube 36.

[0025] Furthermore, to facilitate the replacement of the feed tube 2, the feed tube 2 is connected to the first guide cylinder 31 by a thread.

[0026] In addition, in order to guide the movement path of the guide cylinder, guide strips 322 are provided on the upper and lower sides of the second guide cylinder 32 and the third guide cylinder 33. The first guide cylinder 31 slides between the two guide strips 322 in the second guide cylinder 32, and the second guide cylinder 32 slides between the two guide strips 322 in the third guide cylinder 33.

[0027] like Figure 1 , 2As shown, the telescopic mechanism 3 is fixed on the horizontal mechanism 4. The horizontal mechanism 4 includes a support plate 41 located on one side of the outlet of the equipment box 1. A drive wheel 42 and a driven wheel 43 are rotatably connected to the center of the bottom of the support plate 41. A rotating motor 44 is mounted on one side of the support plate 41 via a bracket. The output end of the rotating motor 44 is connected to the drive wheel 42. The drive wheel 42 and the driven wheel 43 rotate along the groove 451 of the track 45. The track 45 is fixed on the track bracket 46. The rotating motor 44 drives the drive wheel 42 to rotate along the groove 451, thereby driving the support plate 41 and its components to move horizontally left and right.

[0028] Furthermore, the outlet of the equipment box 1 is provided with a corrugated pipe 11. The corrugated pipe 11 passes through the support plate 41 and connects to the third guide cylinder 33 of the telescopic mechanism 3. The groove 451 of the track 45 is arc-shaped. Therefore, the movement trajectory of the support plate 41 and its components is an arc-shaped circle with the connection between the corrugated pipe 11 and the outlet of the equipment box 1 as the center. The corrugated pipe 11 connects the equipment box 1 and the telescopic mechanism 3, which can satisfy the horizontal movement of the feeding tube 2 and at the same time provide a passage for the core wire between the equipment box 1, the telescopic mechanism 3 and the feeding tube 2.

[0029] The lifting mechanism 5 of this utility model includes a lifting hydraulic cylinder 51, which is hinged to a hydraulic cylinder base 52. The hydraulic cylinder base 52 is fixed to one side of a support plate 41. The support plate 41 is also fixedly connected to a guide cylinder base 38, which is hinged to a third guide cylinder 33. The bottom of the third guide cylinder 33 is hinged to the output end of the lifting hydraulic cylinder 51. The extension rod of the lifting hydraulic cylinder 51 drives the third guide cylinder 33 and its internal components to rotate, thereby realizing the up and down movement of the feed tube 2 opening position.

[0030] Work process:

[0031] 1. The core wire enters the equipment box 1 from the inlet, and then exits from the outlet at a certain speed under the action of the motor and rollers. It then enters the third guide tube 37 along the corrugated pipe 11, and then passes through the second guide tube 36 and the first guide tube 35 to enter the feeding tube 2. Finally, it enters the molten steel in the ladle from the opening of the feeding tube 2. Adjusting the position of the opening of the feeding tube 2 can change the initial position of the core wire entering the molten steel.

[0032] 2. Using the lifting mechanism 5, the telescopic rod of the lifting hydraulic cylinder 51 drives the telescopic mechanism 3 to rotate around the guide cylinder base 38, thereby adjusting the vertical distance between the feed pipe 2 opening and the molten steel surface.

[0033] 3. Using the horizontal mechanism 4, the drive wheel 42 is driven to rotate by the rotating motor 44. At the same time, the drive wheel 42 is located in the groove 451 of the track 45, and the groove 451 is arc-shaped, thereby driving the feed tube 2 to move laterally. The moving stroke can be adjusted according to the diameter of the ladle.

[0034] 4. Using the telescopic mechanism 3, the second guide cylinder 32 is moved by the electric push rod 34, and then the moving gear 321 on the second guide cylinder 32 drives the first guide cylinder 31 to move, thereby realizing the extension and retraction of the feeding tube 2 along the radial direction of the ladle;

[0035] 5. The feeding position is adjusted in the longitudinal, transverse and radial directions by the lifting mechanism 5, the horizontal mechanism 4 and the telescopic mechanism 3 of the guiding device, thereby increasing the coverage area of ​​the core wire, reducing the local reaction dead zone and increasing the absorption rate of the core wire.
