Description

Technical Field

[0001] This utility model relates to the field of cored wire infeed technology, and specifically to a cored wire infeed guide device. Background Technology

[0002] Cored wire is made by wrapping alloy powder around a strip of steel. Depending on the alloy powder, it can be classified as: silicon-calcium cored wire, silicon-manganese-calcium cored wire, silicon-calcium-barium cored wire, barium-aluminum cored wire, aluminum-calcium cored wire, calcium-iron cored wire, pure calcium cored wire, etc. Its appearance resembles a coil. Cored wire is suitable for steelmaking and casting. In steelmaking, it can purify the morphology of steel inclusions, improve the castability of molten steel, and enhance the performance of the steel. During use, a wire feeder is used to feed the cored wire into the molten steel near the bottom of the ladle at a certain speed. After the outer sheath of the cored wire melts, the core can be fully dissolved in the ideal position, producing a chemical reaction that effectively avoids reaction with air and slag, thus improving the quality of steelmaking and casting products.

[0003] Currently, cored wire is generally stored in coils. During the drawing process, the cored wire is initially coiled and has a large coercivity, which causes the cored wire to have a certain degree of curvature during the wire feeding process. It will not enter the molten steel in a straight direction, making it difficult for the cored wire to reach the expected position, thereby reducing the accuracy of wire feeding.

[0004] Therefore, it is of great importance to design a cored wire inlet guide device to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a cored wire feeding guide device. This cored wire feeding guide device aims to solve the technical problems caused by the high initial curvature and large coercivity of cored wires stored in coils under existing technologies, which makes it easy for the wires to deviate from the straight path during feeding, thus reducing the accuracy of wire feeding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cored wire inlet guide device includes a mounting frame, with guide frames fixedly mounted at both the front and rear ends of the top of the mounting frame, and a fixed frame fixedly mounted on the top of the mounting frame and between the two sets of guide frames, and a linear guide cylinder slidably connected to the top of the fixed frame. Both sets of guide frames have a fixed base fixedly installed at the bottom of their inner sides. Both sets of guide frames have an adjusting base slidably connected to their inner sides above the fixed bases. Both sets of guide frames have an adjusting screw threadedly connected to their inner top sides, and the bottom end of the adjusting screw is rotatably connected to the top of the adjusting base. Both the fixed base and the adjusting base have longitudinal straightening pressure rollers rotatably connected to their front sides. Both sets of guide frames have a limit frame fixedly installed on their front sides. Both ends of the front sides of both limit frames have transverse straightening pressure rollers slidably connected to their left and right ends. Both sets of limit frames have a bidirectional screw installed at their top ends, between the two transverse straightening pressure rollers. The top end of the transverse straightening pressure roller is threadedly connected to the bidirectional screw via a connecting block.

[0007] As a preferred embodiment of this utility model, a conveying motor is fixedly installed at the front end of the top of the mounting frame and on the right side of the guide frame. The longitudinal straightening pressure roller is rotatably connected to the fixed seat and the adjusting seat through a connecting shaft. The drive end of the conveying motor is connected to the right end of the connecting shaft inside the two sets of fixed seats through a synchronous pulley set.

[0008] As a preferred embodiment of this utility model, a rotating wheel is fixedly installed at the top end of the adjusting screw, and the bottom end of the adjusting screw is rotatably connected to the adjusting seat through a bearing.

[0009] As a preferred embodiment of this utility model, a groove is provided at the bottom of the front of the limiting frame, and the bottom of the transverse straightening pressure roller is slidably connected to the groove through a slider. The transverse straightening pressure roller is rotatably connected between the connecting block and the slider.

[0010] As a preferred embodiment of this utility model, an operating knob is fixedly connected to the front end of the bidirectional screw, a locking gear is fixedly installed on the outside of the operating knob, a locking pull post is slidably connected to the left side of the limiting frame and outside the locking gear, the top end of the locking pull post meshes with the locking gear through a locking tooth block, and a spring is sleeved on the outside of the top end of the locking pull post.

[0011] As a preferred embodiment of this utility model, the front end of the linear guide cylinder is provided with a tapered inlet groove.

[0012] As a preferred embodiment of this utility model, the left and right ends of the bottom of the linear guide cylinder are slidably connected to the inner side of the fixed frame through adjusting edges, and adjusting bolts are provided at the front and rear ends of the two sets of adjusting edges. Adjusting waist holes are provided on the outer side of the fixed frame at positions corresponding to the adjusting bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, through the coordinated design of the guide frame, the fixed frame, and the linear guide cylinder, the rotating adjusting screw drives the adjusting seat to slide up and down along the guide frame via threaded transmission. The adjusting seat drives the upper longitudinal straightening pressure roller to move synchronously, forming an adjustable-gap clamping surface with the pressure roller on the fixed seat. When the cored wire passes between the two sets of longitudinal straightening pressure rollers, the upper and lower longitudinal straightening pressure rollers apply vertical pressure to the coiled cored wire. At the same time, the longitudinal straightening pressure rollers passively rotate with the cored wire feed, reducing friction loss. The rotating bidirectional screw drives the connecting blocks at both ends to move synchronously. The connecting blocks drive the transverse straightening pressure roller along the front of the limiting frame. As the cored wire slides horizontally between two sets of transverse straightening rollers, the transverse straightening rollers eliminate the transverse bending of the cored wire, the longitudinal straightening rollers resolve the vertical bending caused by the steel strip curling, and the transverse straightening rollers correct the horizontal serpentine bends, forming a three-dimensional straightening system. It then passes through a straight guide cylinder, ensuring that the cored wire is in a straight conveying state after being straightened and exited from the guide frame. Finally, it undergoes secondary straightening through a second set of guide frames, effectively eliminating the initial curvature and coercivity of the coiled cored wire, achieving straight feeding of the cored wire, significantly improving feeding accuracy, and allowing adjustment according to the specifications of the cored wire.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figures 1-4 This utility model provides a technical solution: A cored wire inlet guide device includes a mounting frame 1, with guide frames 2 fixedly installed at both the front and rear ends of the top of the mounting frame 1, and a fixing frame 3 fixedly installed on the top of the mounting frame 1 and between the two sets of guide frames 2. A linear guide cylinder 4 is slidably connected to the top of the fixing frame 3.

[0018] First, a fixed base 201 is fixedly installed at the bottom of the inner side of each of the two sets of guide frames 2. An adjusting base 202 is slidably connected to the inner side of each of the two sets of guide frames 2 and above the fixed base 201. An adjusting screw 203 is threadedly connected to the top of the inner side of each of the two sets of guide frames 2, and the bottom end of the adjusting screw 203 is rotatably connected to the top of the adjusting base 202. A longitudinal straightening pressure roller 204 is rotatably connected to the front of both the fixed base 201 and the adjusting base 202. A fixed base 204 is fixedly installed on the front of each of the two sets of guide frames 2. The system is equipped with limit frames 205, and transverse straightening pressure rollers 206 are slidably connected to the left and right ends of the front of the two sets of limit frames 205. A bidirectional screw 207 is installed at the top of the two sets of limit frames 205 and between the two sets of transverse straightening pressure rollers 206. The top of the transverse straightening pressure rollers 206 is threadedly connected to the bidirectional screw 207 through a connecting block 208. Rotating the adjusting screw 203 drives the adjusting seat 202 to slide up and down along the guide frame 2 through threaded transmission. The adjusting seat 202 drives the upper longitudinal straightening. The pressure rollers 204 move synchronously, forming an adjustable-gap clamping surface with the pressure rollers on the fixed base 201. When the cored wire passes between the two sets of longitudinal straightening pressure rollers 204, the upper and lower longitudinal straightening pressure rollers 204 apply vertical pressure to the coiled cored wire. At the same time, the longitudinal straightening pressure rollers 204 passively rotate with the cored wire feed to reduce friction loss. The rotating bidirectional screw 207 drives the connecting blocks 208 at both ends to move synchronously. The connecting blocks 208 drive the transverse straightening pressure roller 206 along the limiting frame 205. The front side slides horizontally. When the cored wire passes between the two sets of transverse straightening rollers 206, the transverse straightening rollers 206 eliminate the transverse bending of the cored wire, the longitudinal straightening rollers 204 solve the vertical bending caused by the steel strip curling, and the transverse straightening rollers 206 correct the horizontal serpentine bending, forming a three-dimensional straightening system. This effectively eliminates the influence of the initial curvature and coercivity of the coiled cored wire, realizes the straight feeding of the cored wire, significantly improves the wire feeding accuracy, and can be adjusted according to the specifications of the cored wire.

[0019] Furthermore, a conveyor motor 209 is fixedly installed at the front end of the top of the mounting frame 1 and on the right side of the guide frame 2. The longitudinal straightening pressure roller 204 is rotatably connected to the fixed seat 201 and the adjusting seat 202 through the connecting shaft 210. The drive end of the conveyor motor 209 is connected to the right end of the connecting shaft 210 in the two sets of fixed seats 201 through the synchronous pulley set 211. The conveyor motor 209 drives the connecting shaft 210 in the two sets of fixed seats 201 to rotate synchronously through the synchronous pulley set 211, thereby realizing the active traction function of the longitudinal straightening pressure roller 204, ensuring that the cored wire obtains stable forward power during the straightening process, and avoiding stagnation caused by coercivity.

[0020] Then, a rotating wheel 212 is fixedly installed at the top of the adjusting screw 203, and the bottom end of the adjusting screw 203 is rotatably connected to the adjusting seat 202 through a bearing. By rotating the rotating wheel 212 at the top, the adjusting screw 203 is driven to rotate. The threaded transmission of the adjusting screw 203 pushes the adjusting seat 202 to slide vertically along the guide frame 2, so as to realize the precise lifting and lowering adjustment of the longitudinal straightening pressure roller 204. The bottom end of the adjusting screw 203 is connected to the adjusting seat 202 through a bearing, which ensures the smooth sliding of the adjusting seat 202 while transmitting the driving force.

[0021] Furthermore, a groove 213 is provided at the bottom of the front of the limiting frame 205. The bottom of the transverse straightening pressure roller 206 is slidably connected to the groove 213 via a slider 214. The transverse straightening pressure roller 206 is rotatably connected between the connecting block 208 and the slider 214. The transverse straightening pressure roller 206 cooperates with the groove 213 of the limiting frame 205 via the slider 214 at the bottom to achieve lateral displacement adjustment along the groove 213. The transverse straightening pressure roller 206 is rotatably connected to the slider 214 via the connecting block 208, and maintains free rotation during sliding to avoid frictional resistance with the cored wire.

[0022] The bidirectional screw 207 has an operating knob 215 fixedly connected to its front end. A locking gear 216 is fixedly installed on the outside of the operating knob 215. A locking pull post 217 is slidably connected to the left side of the limiting frame 205 and outside the locking gear 216. The top end of the locking pull post 217 meshes with the locking gear 216 through a locking tooth block 218. A spring 219 is sleeved on the outside of the top end of the locking pull post 217. Rotating the operating knob 215 drives the bidirectional screw 207 to rotate, and the connecting block 208... Under the connection, the distance between the horizontal straightening pressure rollers 206 at both ends is adjusted synchronously to adapt to the straightening requirements of cables of different specifications. Before adjustment, the locking pull column 217 is pulled down to disengage the locking tooth block 218 from the locking gear 216, so that the operating knob 215 can rotate normally. After adjustment, the locking pull column 217 is released, and the elastic force of the spring 219 pushes the locking tooth block 218 to re-engage the locking gear 216, preventing the rotation of the bidirectional screw 207 from causing the horizontal straightening pressure roller 206 to shift.

[0023] Secondly, a tapered inlet groove 401 is provided at the front end of the linear guide cylinder 4. The design of the tapered inlet groove 401 allows the cored wire to enter the linear guide cylinder 4 smoothly, reducing the initial frictional resistance.

[0024] Finally, both the left and right ends of the bottom of the linear guide cylinder 4 are slidably connected to the inner side of the fixed frame 3 through adjusting edges 402. Adjusting bolts 403 are inserted through the front and rear ends of the two sets of adjusting edges 402. Adjusting waist holes 404 are opened on the outer side of the fixed frame 3 at positions corresponding to the adjusting bolts 403. The linear guide cylinder 4 is slidably connected to the inner side of the fixed frame 3 through the adjusting edges 402 at the bottom, so as to realize flexible adjustment of the height position. During the adjustment process, the nut on the adjusting bolt 403 is loosened first, and the adjusting bolt 403 slides inside the adjusting waist hole 404 during the adjustment process. After the adjustment is completed, the nut on the adjusting bolt 403 is tightened to fix the position of the linear guide cylinder 4, so as to ensure that the cored wire is in a straight conveying state after being straightened and led out from the guide frame 2. Finally, it is straightened again through the second set of guide frames 2, thus ensuring the straight feed of the cored wire and significantly improving the wire feeding accuracy.

[0025] In this embodiment, the specific implementation scenario is as follows: the rotating adjusting screw 203 drives the adjusting seat 202 to slide up and down along the guide frame 2 via threaded transmission. The adjusting seat 202 drives the upper longitudinal straightening pressure roller 204 to move synchronously, forming an adjustable-gap clamping surface with the pressure roller on the fixed seat 201. When the cored wire passes between the two sets of longitudinal straightening pressure rollers 204, the upper and lower longitudinal straightening pressure rollers 204 apply vertical pressure to the coiled cored wire. At the same time, the longitudinal straightening pressure rollers 204 passively rotate with the cored wire feed to reduce friction loss. The rotating bidirectional screw 207 drives the connecting blocks 208 at both ends to move synchronously. The connecting blocks 208 drive the transverse straightening pressure roller 206 to slide horizontally along the front of the limiting frame 205. When the cored wire passes between the two sets of transverse straightening rollers 206, the transverse straightening rollers 206 eliminate the transverse bending of the cored wire, the longitudinal straightening rollers 204 solve the vertical bending caused by the steel strip curling, and the transverse straightening rollers 206 correct the horizontal serpentine bends, forming a three-dimensional straightening system. Then it passes through the straight guide cylinder 4 to ensure that the cored wire is in a straight conveying state after being straightened and discharged from the guide frame 2. Finally, it is straightened again through the second set of guide frames 2. The whole operation process is simple and convenient. This utility model can effectively eliminate the influence of the initial curvature and coercivity of the coiled cored wire through design, realize the straight feeding of the cored wire, significantly improve the wire feeding accuracy, and can be adjusted according to the specifications of the cored wire.
