Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of steelmaking production equipment, and in particular to a calcium wire guiding structure of a wire feeder. BACKGROUND
[0002] The calcium wire feeder is a key equipment for adding calcium elements to molten steel in the calcium treatment process of steelmaking. Through the action of the wire feeder, the calcium wire coated with a metal shell is sent into the molten steel at a controlled speed, so that the calcium elements in the molten steel undergo deoxidation and desulfurization reactions, refine the molten steel grains, and improve the performance of the steel. However, the calcium wire feeder is often limited by the structure of the equipment, environmental factors, and the characteristics of the calcium wire during actual use, affecting the wire feeding efficiency and the utilization rate of calcium elements. For example, when the wire feeding speed is unstable or the guiding structure is imperfect, problems such as calcium wire jamming, slipping, and breaking are likely to occur, thereby affecting the stability of the process and the quality of the molten steel.
[0003] During the calcium wire feeding process, the calcium wire is usually pulled out from the ring-shaped wire frame and into the wire feeder conveying path. Due to the elastic and flexible characteristics of the calcium wire, as well as the irregular arrangement of the calcium wire in the wire frame, the calcium wire often exhibits a swinging phenomenon at the moment of being pulled out. The swinging causes instability in the direction and tension of the calcium wire, making it difficult for the wire feeder guiding structure to smoothly convey the calcium wire, which can easily lead to jamming or slipping problems. In addition, when the calcium wire stays in the wire feeder for too long or moves at a slow speed, the calcium wire is prone to melting at the surface of the molten steel or being oxidized by air, ultimately reducing the recovery rate of calcium elements, affecting the control of the composition of the molten steel, and even increasing production costs.

DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions in the present application will be clearly and completely described below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.
[0031] The embodiment of the present application discloses a calcium wire guide structure of a yarn feeder. The embodiment of the present application is implemented in the case that the yarn feeder is at a high point position and the wire frame is at a low point position. Please refer to Figure 1 and Figure 2The calcium wire guiding structure of the wire feeder comprises a mounting seat 3, a limiting piece 4 arranged at the top of the mounting seat 3, and a clamping device 5 arranged at the bottom of the mounting seat 3. The mounting seat 3 is provided with a cavity for the calcium wire 21 to pass through. The limiting piece 4 is funnel-shaped, and the opening near the mounting seat 3 is larger than the opening away from the mounting seat 3, which is used to limit the calcium wire 21 when the calcium wire 21 passes through. The clamping device 5 is used to clamp the mounting seat 3 on the wire frame 2.
[0032] When the calcium wire 21 is conveyed from the wire frame 2 to the wire inlet of the wire feeder 1, the mounting seat 3 is clamped on the wire frame 2 by the clamping device 5, so as to facilitate the fixation of the limiting piece 4 and the guidance of the transmission of the calcium wire 21. The funnel-shaped guide piece is arranged with the large opening facing the mounting seat 3 and the small opening away from the mounting seat 3, so as to facilitate the calcium wire 21 to pass into the guide piece and to limit the calcium wire 21 within the small opening of the guide piece. The swinging range of the calcium wire 21 during the process of being drawn out from the wire frame 2 can be greatly reduced, thereby effectively improving the stability of the calcium wire 21 conveying and ensuring the smoothness of the calcium wire 21 feeding, so as to stabilize and improve the recovery rate of the calcium wire 21, reduce the production cost, and reduce the labor for handling the wire jamming problem.
[0033] Please refer to Figure 3 The limiting piece 4 comprises a plurality of limiting rings 41 with different diameters arranged in the axial direction of the limiting piece 4 in a concentric manner and a plurality of connecting rods 42 arranged around the limiting rings 41. The plurality of limiting rings 41 are arranged in a concentric manner, and the limiting rings 41 with different diameters are arranged from small to large in the direction away from the mounting seat 3 to the direction close to the mounting seat 3. In this embodiment, there are three limiting rings 41 and six connecting rods 42. Each connecting rod 42 is welded and fixed with the three limiting rings 41, thereby forming a funnel-shaped limiting piece 4 with stable structure. In order to reduce the swinging range of the calcium wire 21 and affect the transmission of the calcium wire 21, the small opening diameter of the guide piece should be not greater than the diameter of the calcium wire 21. The limiting piece 4 can be manufactured by using waste iron wire, and the structure is relatively simple and the production cost is relatively low. The limiting piece 4 is provided with four L-shaped rods around, one end of the L-shaped rod is welded with the guide piece, and the other end is welded with the mounting seat 3, thereby fixing the limiting piece 4.
[0034] Please refer to Figure 2 and Figure 4The clamping device 5 comprises a plurality of arc-shaped clamping plates 51 arranged around the peripheral side of the mounting seat 3 and a driving assembly 52 for driving the arc-shaped clamping plates 51 to move close to or away from the center of the mounting seat 3. In order to facilitate operation, two arc-shaped clamping plates 51 are arranged in the embodiment, the two arc-shaped clamping plates 51 are arranged at an angle of 180°, and two groups of driving assemblies 52 are arranged and correspond to the arc-shaped clamping plates 51 respectively. The two groups of driving assemblies 52 respectively drive the two arc-shaped clamping plates 51 to move, so as to clamp and fix the mounting seat 3 on the wire frame 2. As an alternative embodiment, the arc-shaped clamping plates 51 can be three, four or more, and the driving assemblies 52 can be arranged in a synchronous driving structure to synchronously drive the plurality of arc-shaped clamping plates 51 to move, which further facilitates operation but has a relatively complex structure and a high production cost.
[0035] Specifically, please refer to Figure 4 The driving assembly 52 comprises a driving screw 521 and a limiting rod 522, the limiting rod 522 is arranged in parallel with the driving screw 521 and is arranged along the radial direction of the wire frame 2, the arc-shaped clamping plate 51 comprises an arc segment and a connecting segment integrally formed with the top position of the arc segment, the limiting rod 522 and the driving screw 521 penetrate through the connecting segment of the arc-shaped clamping plate 51, the driving screw 521 is rotationally connected with the mounting seat 3 and is threadedly connected with the arc-shaped clamping plate 51, and the limiting rod 522 is fixedly welded with the mounting seat 3 and is slidably connected with the arc-shaped clamping plate 51.
[0036] When the arc-shaped clamping plate 51 needs to be controlled to move, the driving screw 521 is rotated, the arc-shaped clamping plate 51 moves along the length direction of the driving screw 521 under the driving of the thread, and the limiting rod 522 can limit the arc-shaped clamping plate 51 to prevent the arc-shaped clamping plate 51 from rotating, so that the arc-shaped clamping plate 51 can stably move. The driving mode of the thread can not only enable the arc-shaped clamping plate 51 to stably move but also has the effect of preventing loosening, thereby increasing the stability of fixing the mounting seat 3.
[0037] In order to facilitate the staff to rotate the driving screw 521, the driving screw 521 is fixedly welded with a driving handle 523 at the end away from the mounting seat 3, and the driving handle 523 adopts a key handle.
[0038] Since the rigid contact between the arc-shaped clamping plate 51 and the wire frame 2 can cause damage to the structure and the stability is poor, in the embodiment, a buffer layer 511 is fixedly bonded to the inner side of the arc-shaped clamping plate 51, and the buffer layer 511 is made of elastic materials such as rubber or silica gel. By arranging the buffer layer 511, the contact between the arc-shaped clamping plate 51 and the wire frame 2 is changed to soft contact, so as to reduce the possibility of damaging the arc-shaped clamping plate 51 or the wire frame 2, increase the friction force, prevent slipping, and improve the stability of clamping the wire frame 2 by the arc-shaped clamping plate 51.
[0039] The calcium line 21 is usually wound into a cylindrical shape and embedded in the wire frame 2. During the process of extracting the calcium line 21 from the wire frame 2, the calcium line 21 is extracted from the inside of the wire frame 2. During this process, the calcium line 21 swings more randomly. In order to further improve the stability of the calcium line 21 transmission, a guide ring 6 is arranged between the limiting piece 4 and the wire frame 2. The guide ring 6 is rotatably arranged on the mounting seat 3 within the cavity range of the mounting seat 3. The rotation axis is arranged along the axis of the limiting piece 4. The axis of the guide ring 6 is arranged in parallel with the axis of the limiting piece 4. The guide ring 6 and the limiting piece 4 are arranged eccentrically, so that the guide ring 6 makes a circular motion around the axis of the limiting piece 4 on the side of the limiting piece 4 close to the wire frame 2. After the calcium line 21 is extracted from the wire frame 2, it passes through the guide ring 6. During the swinging process, the calcium line 21 makes a standard circular motion under the action of the guide ring 6, thereby reducing the irregular fluctuation of the calcium line 21 and further improving the stability of the calcium line 21 transmission.
[0040] Specifically, please refer to Figure 4 and Figure 5 The mounting seat 3 is a hollow circular ring, and the inner wall is provided with a ring groove 31. A rotating ring 32 is coaxially arranged inside the mounting seat 3. The guide ring 6 is welded and fixed to the rotating ring 32 through a connecting rod. The ring groove 31 allows the connecting rod to pass through the inner wall of the mounting seat 3, so that the guide ring 6 can make a complete circular motion around the axis of the mounting seat 3. The structure of the rotating ring 32 embedded in the mounting seat 3 can greatly improve the stability of the guide ring 6 during rotation.
[0041] In order to reduce the resistance of the calcium line 21 contacting the inner wall of the guide ring 6, a plurality of balls 61 are embedded in the inner wall of the guide ring 6. The plurality of balls 61 are arranged at equal intervals on the inner wall of the guide ring 6. The plurality of balls 61 guide the calcium line 21 passing through the guide ring 6, which can adapt to the circular extraction of the calcium line 21, thereby facilitating the transportation of the calcium line 21.
[0042] In order to increase the distance between the limiting piece 4, the guide ring 6 and the wire frame 2, and to leave a certain transition space for the calcium line 21, a plurality of support legs 7 are welded and fixed to the bottom of the mounting seat 3. The support legs 7 are inverted T-shaped, and a plurality of support legs 7 are arranged at equal intervals on the bottom of the mounting seat 3. The arrangement of the support legs 7 can also increase the installation space of the clamping device 5, increase the distance between the driving screw 521 and the limiting rod 522, and thereby increase the support strength of the movement of the arc-shaped clamping plate 51, so as to improve the stability of the device.
[0043] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
