Description

Technical Field

[0001] This utility model belongs to the field of cored wire production technology, specifically relating to a tensioning structure for a cored wire making machine. Background Technology

[0002] Cored wire, a functional material widely used in industries such as steel and casting, directly impacts product performance and quality stability in subsequent production processes. In steelmaking, cored wire allows for the precise addition of various alloying elements, refining agents, or inoculants to molten steel, enabling accurate control over the steel's composition and quality, thereby improving key performance indicators such as strength, toughness, and corrosion resistance. In casting, cored wire also helps improve the microstructure and properties of castings, reducing defects.

[0003] In the production process of cored wire, from the unwinding of raw materials to the winding of the final finished wire, each stage requires ensuring that the wire is under appropriate tension. However, since cored wire is usually composed of a metal sheath wrapping a powdery, granular, or filamentous core material, its structure is relatively complex. This makes it prone to unstable tension during the wire-making process, affecting the continuity and efficiency of production. Furthermore, it places an additional load on the equipment's transmission system, increasing production costs and equipment maintenance difficulty. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning structure for a cored wire making machine, which aims to solve the problems mentioned in the background art.

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

[0006] A tensioning structure for a cored wire making machine includes,

[0007] The support assembly includes a base, a column fixedly installed in the middle of the base, a support rod fixedly installed on the side wall of the base, and a caster wheel rotatably installed at the end of the support rod;

[0008] The tensioning mechanism includes a top rod movably inserted into the center of the column, a frame fixedly connected to the top of the top rod, a connector rotatably installed on the side wall of the frame, a shaft movably inserted into the middle of the connector, and a support member adapted to be installed at the end of the shaft. The support member is used in conjunction with the connector.

[0009] As a preferred embodiment of this utility model, the tensioning mechanism further includes a support plate slidably installed in the middle of the frame, and the end of the support member is connected to the side wall of the support plate through a bearing.

[0010] As a preferred embodiment of the present invention, the tensioning mechanism further includes a handle bolt threaded to the side wall of the connector, the end of which passes through the side wall of the connector and cooperates with the shaft.

[0011] As a preferred embodiment of the present invention, the tensioning mechanism further includes a baffle rotatably mounted on the end of the shaft, the baffle being mounted on the outside of the frame.

[0012] As a preferred embodiment of this utility model, the tensioning mechanism further includes a spring fixedly sleeved on the side wall of the shaft, one end of the spring being in elastic contact with the outer side wall of the frame, and the other end of the spring being in elastic contact with the inner side wall of the baffle.

[0013] As a preferred embodiment of this utility model, the tensioning mechanism further includes an air cylinder installed on the side wall of the frame, and the output end of the air cylinder is connected to the inside of the top rod through an air pipe.

[0014] As a preferred embodiment of the present invention, the tensioning mechanism further includes a plug inserted into the side wall of the top rod, the end of the plug extending into the interior of the top rod.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: By cooperating with the support component and the tensioning mechanism, the tension of the cored wire is adjusted during the production process, ensuring that the cored wire receives stable and appropriate tension throughout the entire production process, thus avoiding uneven wire thickness caused by uneven tension. Whether in the initial stage of core wire wrapping the outer sheath or in subsequent processing stages, the cored wire maintains a uniform diameter, and the stable tension effectively prevents uneven distribution of the core material within the sheath, such as accumulation, displacement, or voids. This allows the cored wire to run smoothly between various components of the wire-making machine, avoiding wire slack and tangling on equipment components due to insufficient tension, as well as wire breakage caused by excessive tension, ensuring consistent product quality, and reducing severe friction between the cored wire and equipment guide wheels, molds, and other components due to unstable tension.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a tensioning structure for a cored wire making machine, comprising:

[0027] The support assembly 100 includes a base 101, a column 102 fixedly installed in the middle of the base 101, a support rod 103 fixedly installed on the side wall of the base 101, and a caster wheel 104 rotatably installed at the end of the support rod 103.

[0028] The tensioning mechanism 200 includes a top rod 201 movably inserted into the center of the column 102, a frame 202 fixedly connected to the top of the top rod 201, a connector 203 rotatably installed on the side wall of the frame 202, a shaft 204 movably inserted into the middle of the connector 203, and a support 205 adapted to be installed at the end of the shaft 204. The support 205 is used in conjunction with the connector 203.

[0029] The support component 100 is used to cooperate with the tensioning mechanism 200 to maintain the stability of the tensioning mechanism 200's position. Adjusting the extension length of the top rod 201 along the column 102 allows for adjustment of the height of the frame 202, facilitating docking with the linear motion machine and keeping the cored wire in a taut state. A rotatable connector 203 is installed on the side wall of the frame 202, and a shaft 204 with a support 205 is installed in the middle of the connector 203. Adjusting the position of the shaft 204 changes the distance between the support 205 and the connector 203, adapting to the conveying of cored wires of different diameters, preventing the cored wire from shaking, and maintaining the cored wire in a taut state to ensure production accuracy.

[0030] Specifically, the tensioning mechanism 200 also includes a support plate 206 that is slidably installed in the middle of the frame 202, and the end of the support member 205 is connected to the side wall of the support plate 206 by a bearing.

[0031] Among them, a support plate 206 is installed in the middle of the frame 202 and docks with the support member 205, which can combine multiple support members 205 together and maintain the stability of the position of the support member 205.

[0032] Furthermore, the tensioning mechanism 200 also includes a handle bolt 207 threaded to the side wall of the connector 203, the end of which passes through the side wall of the connector 203 and is used in conjunction with the shaft 204.

[0033] Among them, a handle bolt 207 is installed on the side wall of the connector 203. Tightening the handle bolt 207 can lock the shaft 204 on the basis of the installation on the side wall of the connector 203, maintain the stability of the position of the shaft 204 with the support 205 installed, and facilitate the support of the cored wire of the corresponding diameter.

[0034] Furthermore, the tensioning mechanism 200 also includes a baffle 208 rotatably mounted at the end of the shaft 204, the baffle 208 being mounted on the outside of the frame 202.

[0035] Among them, a baffle 208 is added to the end of the shaft 204. The baffle 208 is used to keep multiple sets of shafts 204 moving synchronously and to adjust the overall width of the tensioning mechanism 200, so as to facilitate tensioning and supporting cored wires of different diameters.

[0036] Preferably, the tensioning mechanism 200 further includes a spring 209 fixedly sleeved on the side wall of the shaft 204, one end of the spring 209 elastically contacting the outer side wall of the frame 202, and the other end of the spring 209 elastically contacting the inner side wall of the baffle 208.

[0037] Among them, a spring 209 is installed in the middle of the shaft 204 and connected to the baffle 208 to maintain the smooth movement of the shaft 204 and prevent the baffle 208 from colliding with the frame 202.

[0038] It should be noted that the tensioning mechanism 200 also includes an air cylinder 210 installed on the side wall of the frame 202, and the output end of the air cylinder 210 is connected to the inside of the top rod 201 through an air pipe.

[0039] Among them, an air cylinder 210 is added to the side wall of the frame 202 to connect with the top rod 201, so as to facilitate the filling of gas into the top rod 201, adjust the height of the top rod 201 at the end of the column 102, adapt to the adjustment of the height of the tensioning mechanism 200, and keep the core wire in a taut state.

[0040] Preferably, the tensioning mechanism 200 further includes a plug 211 that is sealed and inserted into the side wall of the top rod 201, with the end of the plug 211 extending into the interior of the top rod 201.

[0041] Among them, an insert rod 211 is added to the side wall of the top rod 201 to facilitate closing the top rod 201. Loosening the insert rod 211 facilitates venting the top rod 201, so that the top rod 201 is subjected to force to expel the gas and descends at the end of the column 102, thereby reducing the height of the tensioning mechanism 200.

[0042] In use, gas is injected into the top rod 201 through the air pump 210, causing the top rod 201 to rise at the end of the column 102, adjusting the height of the frame 202 for easy docking with the linear machine and keeping the cored wire taut. Adjusting the position of the shaft 204 changes the distance between the support 205 and the connector 203, adapting to the conveying of cored wires of different diameters. Then, tightening the handle bolt 207 locks the shaft 204 in place on the side wall of the connector 203, maintaining the stability of the position of the shaft 204 with the support 205 installed.

[0043] In summary, the support component 100 and the tensioning mechanism 200 work together to adjust the tension of the cored wire during production, ensuring that the cored wire receives stable and appropriate tension throughout the entire production process, thus avoiding uneven wire thickness caused by uneven tension. Whether in the initial stage of core wire wrapping or in subsequent processing stages, the cored wire maintains a uniform diameter, and stable tension effectively prevents uneven distribution of the core material within the sheath, such as accumulation, shifting, or voids. This ensures smooth operation of the cored wire among the various components of the wire-making machine, preventing wire slack and tangling on equipment parts due to insufficient tension, and wire breakage due to excessive tension, thus guaranteeing consistent product quality and reducing severe friction between the cored wire and equipment guide wheels, molds, and other components caused by unstable tension.
