Description
Technical Field
[0001] This utility model relates to the field of steel coil processing technology, specifically to a coil edge guiding device for a coil drawing machine. Background Technology
[0002] In the industrial scenario of processing steel coils by coiling machines, the stable and accurate conveying of the coils directly affects the final product quality and production efficiency. As a core raw material in the field of metal processing, steel coils must have their edge deviation strictly controlled during the conveying process. Otherwise, problems such as coil wrinkles and cutting deviations may occur, and even subsequent processes may not be able to proceed normally. As a core component of the coil conveying system, the edge guide device plays a crucial role in correcting the coil conveying trajectory and defining the edge position, and is an important link in ensuring production continuity and product precision. However, most existing guide wheels are fixed installation structures and lack buffering and adjustment capabilities. During the operation of the coiling machine, they are easily affected by external factors such as equipment vibration and coil tension fluctuations, which can cause slight deviation of the steel coil. For thinner steel coils, this deviation will prevent the formation of a buffer space between the edge of the coil and the fixed guide wheel. The extrusion force generated by the rigid contact will directly act on the edge of the thin steel coil, which can easily cause damage and deformation of the coil edge, affecting the product processing quality and making it difficult to meet the processing requirements of high-precision steel coils. Therefore, a roll edge guiding device for a roll drawing machine is proposed to address the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: A winding machine edge guiding device includes a guide seat 1. The inner wall of the guide seat 1 is fitted with symmetrically arranged elastic guiding mechanisms 2. An injection pipe 3 is installed on the outer side of the upper elastic guiding mechanism 2, extending above the guide seat 1. The elastic guiding mechanism 2 includes a fixed plate 21. A guide cylinder 22 is fixed to the center of the inner side of the fixed plate 21. A gas spring 23 is installed at one end inside the guide cylinder 22. The gas spring 23 is connected to a guide contact member 25 via a connector 24, and the guide contact member 25 extends to the guide cylinder 2. 2. External; guide contact 25 includes guide ball 251, which is made of hard alloy material and has extremely high wear resistance and hardness. One end of guide ball 251 is provided with guide ring 252. Both the top and bottom of guide ball 251 are provided with spiral groove 253. The pitch of spiral groove 253 is 1-2mm and the groove depth is 0.5-1mm, which can make the lubricant evenly distributed on its surface when guide ball 251 rotates, forming a continuous lubricating film, effectively reducing the friction coefficient between guide ball 251 and the edge of steel coil. Specifically, by setting a guide ball 251 with multiple sets of gradually changing guide rings 252 through a gas spring 23, and cooperating with the lubricating spiral groove 253 for lubrication and the spherical connector 24 for buffering, the problem of rigid extrusion deformation of the thin steel coil edge by the traditional fixed guide wheel is solved, achieving precise guidance and elastic buffering, ensuring the quality of the thin steel coil edge. The gas spring 23 is made of stainless steel with an elastic modulus of 190-210 GPa. The stainless steel gas spring 23 has excellent corrosion resistance and is suitable for the working environment of the coiling machine. The elastic modulus of 190-210 GPa ensures that it provides stable and sufficient elastic support for the guide ball 251, which not only ensures the effectiveness of buffer adjustment, but also avoids fatigue failure of the gas spring due to frequent extension and contraction. As a further implementation of this solution, the connector 24 includes a spherical seat 241 and a spherical rod 242. The spherical seat 241 is fixedly connected to the telescopic end of the gas spring 23. The spherical rod 242 is welded and fixed to the center of the inner side of the guide ball 251. The connecting ball end of the spherical rod 242 is rotatably connected to the inner side of the spherical seat 241. The rotational cooperation between the spherical seat 241 and the spherical rod 242 allows the guide ball 251 to flexibly adapt to angle changes during buffer adjustment. The cooperation gap between the spherical seat 241 and the spherical rod 242 is 0.02-0.05mm. The cooperation gap of 0.02-0.05mm is extremely small, which not only ensures the smooth rotation of the spherical seat 241 and the spherical rod 242, allowing the guide ball 251 to flexibly adapt to angle changes during buffer adjustment, but also effectively transmits the elastic force of the gas spring 23. As a further implementation of this solution, the axis of the gas spring 23 and the axis of the fixed disk 21 are on the same straight line. The gas spring 23 and the fixed disk 21 are fixedly connected. The coaxial design of the gas spring 23 and the fixed disk 21 ensures that the elastic guide mechanism 2 is subjected to uniform force, making the buffer adjustment of the guide ball 251 more stable and improving the structural stability of the overall guide device. As a further implementation of this solution, the axis of the guide ring 252 and the axis of the guide ball 251 are located on the same axis. The inner side of the guide ring 252 is an inclined surface, and there are multiple guide rings 252. The multiple guide rings 252 are gradually reduced in size with the axis of the guide ball 251 as the direction. To further explain, multiple sets of gradually decreasing guide rings 252 guide the offset edge of the steel coil to automatically slide into the two guide balls 251 to achieve buffering, avoid rigid compression, and at the same time achieve precise guidance to adapt to steel coils with different offset amounts. As a further implementation of this solution, the guide ball 251 has a spherical structure. A concentrating groove 254 and a distributing groove 255 are provided on one side of the guide ball 251. The concentrating groove 254 is connected to the corresponding spiral groove 253 through the distributing groove 255. The inner side of the concentrating groove 254 has a spherical structure, and the inner side of the distributing groove 255 has an inclined structure. To further explain, the combination of the concentrating groove 254, the distribution groove 255 and the spiral groove 253 ensures that the lubricant evenly covers the surface of the guide ball 251, reducing frictional damage. At the same time, the spherical structure of the guide ball 251 is adapted for buffer adjustment, improving the synergistic effect of lubrication and buffering. As a further implementation of this solution, the inner wall of the guide seat 1 is equipped with multiple elastic guide mechanisms 2 arranged symmetrically on the upper and lower sides. The elastic guide mechanisms 2 located on the same side are arranged linearly. The fixed plate 21 is fixed to the guide seat 1 by bolts to realize multi-segment guidance and buffering of the edge of the steel coil. As a further implementation of this solution, the bottom of the filling pipe 3 extends through the inner side of the guide cylinder 22, and the bottom end of the filling pipe 3 corresponds to the position of the concentrating groove 254, ensuring efficient injection and uniform distribution of lubricant, guaranteeing lubrication effect, reducing frictional damage between the guide ball 251 and the edge of the steel coil, and improving the protective performance of the guiding device.
[0017] Workflow: Before use, lubricant is added to the centralized trough 254 through the filling pipe 3. The lubricant in the centralized trough 254 flows to the spiral trough 253 through the distribution trough 255. The lubricant in the spiral trough 253 evenly covers the corresponding surfaces of the two guide balls 251 due to its own structure, forming a lubricating film, reducing excessive friction between the edge of the steel coil and the guide balls 251, and avoiding edge damage. The edge of the steel coil is placed between the corresponding guide rings 252. Multiple gradually decreasing guide rings 252 accurately guide the edge of the steel coil, ensuring the accuracy of the coil conveying direction. When the operation of the coiling machine is affected by external factors, the steel coil deviates and applies excessive pressure to the guide ring 252. The edge of the steel coil will automatically slide into the space between the two guide balls 251 along the contact slope of the guide ring 252. At this time, the edge of the coil exerts a squeezing force on the guide balls 251, causing the upper and lower guide balls 251 to overcome the elastic force of the gas spring 23 and move away from each other. Through the rotational cooperation of the ball seat 241 of the connector 24 and the ball rod 242, flexible buffer adjustment is achieved, effectively offsetting the excessive squeezing force caused by the deviation, and avoiding damage and deformation of the thin steel coil edge due to rigid squeezing. During the coil winding operation, the edge of the coil that contacts the guide ball 251 will drive the guide ball 251 to rotate, further reducing friction damage. The gas spring 23 always provides elastic support for the guide ball 251, ensuring that the guide ball 251 is reset during normal coil conveying, maintaining a stable guiding state, and ensuring the stability of coil processing quality.
