Abstract
Description
Technical Field
[0001] The utility model relates to the field of steelmaking wire feeding equipment, in particular to a bracket with a wire-scattering prevention function. Background Art
[0002] Wire feeding technology is a smelting process outside the furnace. Its general principle is: the reagents used in the smelting process (such as desulfurization and deoxidizer) are crushed into particles, and then these reagents are wrapped into a cored wire with cold-rolled low-carbon steel. After the cored wire is formed, the wire feeding machine is used to allow these cored wires to reach the bottom of the ladle. After that, the cored wire continues to melt at the bottom of the ladle, and the reagents carried in it are melted in the molten steel and continuously interact with it to achieve the purpose of treating the molten steel (such as desulfurization, changing composition, improving cleanliness, etc.). In the entire production process, it is particularly important to smoothly deliver the cored wire into the molten steel.
[0003] However, in actual work, due to the large size of the coil of the cored wire, ordinary coil racks cannot ensure that the coil is tightened throughout the entire process, especially when the coil is more than half used, the free space between the coil and the rack becomes larger, and the coil is prone to loose wire and tipping over. In order to ensure that it does not affect the work of the wire feeding machine, manual intervention is often required to successfully use up the entire roll of cored wire. Utility Model Content
[0004] The utility model aims to provide a bracket with the function of preventing loose wires, and improves the bracket of a wire feeding machine to ensure that the coil is tightened throughout the whole process and is not easy to loosen.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A bracket with an anti-scattering wire function includes a support mechanism and a central tension mechanism, and the centers of the two are coaxial. The support mechanism includes a support base plate and support side plates distributed circumferentially along the support base plate. The central tension mechanism is located inside a cylindrical structure surrounded by the support base plate and the support side plates, and is used to support the coil of the cored wire.
[0007] The above-mentioned bracket with anti-scattering wire function, the central tension mechanism includes a base plate, a fixed column, a spring and a supporting circular plate, the base plate is axially connected to the supporting base plate, and a fixed column is provided thereon, and multiple springs are respectively arranged on the surrounding walls of the fixed column, and are connected to the supporting circular plate through the springs.
[0008] The above-mentioned bracket with anti-unraveling function, the central tension mechanism also includes a top plate and a limiting part, the top plate is connected to a section fixed away from the bottom plate, the limiting part corresponds to the circular support plate one by one, and includes a connecting rod, a limiting plate, a first limiting groove and a second limiting groove, the connecting rod passes through the upper and lower ends of the circular support plate and is respectively connected to the limiting plates, and the connecting rod can rotate inside the circular support plate, the first limiting groove passes through the upper and lower ends of the top plate, and the second limiting groove passes through the upper and lower ends of the bottom plate.
[0009] The above-mentioned bracket with anti-scattering wire function, the first limiting groove includes a first inner positioning groove and a first outer positioning groove, the cross-section of the first inner positioning groove is a "mouth" shape, and is connected to the first outer positioning groove, and the first outer positioning groove extends to the outside of the top plate (4); the spacing between the two long sides of the first outer positioning groove is greater than the side length of A and less than the side length of B.
[0010] The beneficial effects of adopting the above technical solution are:
[0011] The utility model is arranged perpendicular to the ground, and the coil of the cored wire is sleeved on the outside of the central tension mechanism to prevent the coil from tipping over, and the supporting side plate is inserted into the supporting bottom plate to fasten the coil within the range surrounded by the supporting side plate, so the coil is not easy to loosen, and as the wire feeding machine extracts the core wire, the spring will push the supporting circular plate to move away from the center of the fixed column, thereby increasing the inner diameter of the coil, thereby reducing the spatial freedom between the supporting circular plate and the supporting side plate, and even if the coil is more than half used, the coil will not loosen; the utility model is also provided with a limiting portion, and the supporting circular plate can be fixed through the cooperation of the limiting plate, the first limiting groove and the second limiting groove, so that the coil can be sleeved on the outside of the supporting circular plate.

DETAILED DESCRIPTION
[0020] Example
[0021] like Figure 1-5 As shown, the utility model includes a support mechanism and a central tension mechanism, and the centers of the two are coaxial, the support mechanism includes a support base plate 1 and a plurality of support side plates 2 distributed along the circumference of the support base plate, the cross section of the support base plate 1 is circular, and is provided with a plurality of grooves running through its upper and lower ends, the support side plate 2 is provided with a connecting block at one end close to the support base plate 1, and the support side plate 2 is vertically plugged into the upper end of the support base plate 1 by inserting the connecting block into the groove; when in use, the utility model can fix the support base plate 1 directly on the ground to ensure that the coil bracket is always perpendicular to the ground and will not fall over, and after the coil of the cored wire is placed on the bracket, the coil can be fastened within the range surrounded by the support side plates 2 by plugging the support side plates 2 onto the support base plate 1, and the coil is not easy to loosen.
[0022] like Figure 1 As shown, the central tension mechanism is located at the center of the cylindrical structure surrounded by the supporting bottom plate and the supporting side plates, and is used to support the coil of the cored wire.
[0023] like Figure 4As shown, the central tension mechanism includes a bottom plate 3, a top plate 4, a fixing column 5, a spring 6, a supporting circular plate 7 and a limiting portion. The bottom plate 3 is located on the upper end surface of the supporting bottom plate 1 and is axially connected to the supporting bottom plate 1. After the coil is placed on the bottom plate 3, when the wire feeding machine extracts the core wire, a traction force will be generated on the coil, so that the coil and the central tension mechanism rotate accordingly, but the supporting mechanism remains fixed. The fixing column 5 is located at the center of the bottom plate 3, one end of which is connected to the bottom plate 3, and the other end is connected to the top plate 4. Its cross-section The surface is square, and two springs 6 are respectively installed on the four walls of the fixed column 5, and the supporting circular plates 7 are connected through the springs 6. The four supporting circular plates 7 abut the inner wall of the coil of the cored wire. As the wire feeding machine extracts the core wire, the tightening effect of the coil on the spring 6 and the supporting circular plates 7 becomes smaller, and the spring 6 will push the supporting circular plates 7 to move away from the center of the fixed column 5, thereby increasing the inner diameter of the coil, thereby reducing the spatial freedom between the supporting circular plates 7 and the supporting side plates 2. Even if more than half of the coil is used, the coil will not become loose.
[0024] like Figure 2 and Figure 5 The limiting part of the utility model shown in the figure corresponds one-to-one with the supporting circular plate 7, including a connecting rod 8, a limiting plate 9, a first limiting groove 10 and a second limiting groove 11. The connecting rod 8 passes through the upper and lower ends of the supporting circular plate 7 and is respectively connected to the limiting plates 9, and the connecting rod 8 can rotate inside the supporting circular plate 7. The limiting plate 9 is a rectangular plate-like member. The first limiting groove 10 is located on the top plate 4, and the second limiting groove 11 is located on the bottom plate 3. After the position of the supporting circular plate 7 is fixed by the action of the first limiting groove 10, the second limiting groove 11 and the limiting plate 9, it is convenient to put the coil between the supporting circular plate 7 and the supporting side plate 2.
[0025] like Figure 1 and Figure 2 As shown, the first limiting groove 10 runs through the upper and lower ends of the top plate 4, including a first inner positioning groove 10-1 and a first outer positioning groove 10-2. The cross-section of the first inner positioning groove 10-1 is in the shape of a "mouth" and is connected to the first outer positioning groove 10-2. The first outer positioning groove 10-2 is connected to the outside of the top plate 4. The first limiting groove 10 cooperates with the limiting plate 9 close to the top plate to ensure that the limiting plate 9 can move in a straight line inside the first outer positioning groove 10-2 and can rotate around the connecting rod 8 inside the first inner positioning groove 10-1.
[0026] like Figure 5 As shown, A is the short side on the cross section where the limiting plate 9 is parallel to the top plate 4, and B is the long side on the cross section where the limiting plate 9 is parallel to the top plate 4. The distance between the two long sides of the first outer positioning groove 10-2 is greater than the side length of A and less than the side length of B.
[0027] like Figure 1 and Figure 2 As shown, the second limiting groove 11 passes through the upper and lower ends of the bottom plate 3 and has the same structure as the first limiting groove 10 .
[0028] Workflow:
[0029] 1. Fix the support base plate 1 to the ground, move the supporting circular plate 7 toward the center of the fixed column 5, at this time, the limit plate 9 is in the open state, after the limit plate 9 enters the first inner positioning groove 10-1, rotate one of the limit plates 9 90°, then the limit plates 9 at the upper and lower ends of the connecting rod 8 rotate at the same time, at this time, the limit plate 9 is in the closed state, at this time, the long side B on the limit plate 9 is perpendicular to the long side of the first inner positioning groove 10-1.
[0030] 2. Use a hanger to put the coil of the cored wire on the outside of the supporting circular plate 7, then insert multiple supporting side plates 2 on the supporting bottom plate 1 respectively, and then open the limiting plate 9. At this time, the supporting circular plate 7 abuts against the inner wall of the coil.
[0031] 3. The wire feeder starts to extract the core wire, and at the same time, the bottom plate 3 and the components thereon start to rotate under the traction of the core wire to ensure that the direction of the core wire out of the coil remains unchanged until the entire roll of core wire is used up.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
