Description

Technical Field

[0001] This utility model belongs to the field of wire rolling technology, and specifically relates to a hot continuous rolling device for improving the roundness of stainless steel wire. Background Technology

[0002] Surface defects are a significant issue in the rolling process of metal wire (including bars). These defects include scratches and abrasions, which are among the most common problems and can further affect the roundness of the wire. A common solution is to replace the conveying pipes promptly to prevent scale and impurities accumulated inside from scratching the wire. The pipe replacement locations are particularly important at the beginning and end of the conveying process. The beginning of wire rolling focuses on guiding the heated bar into the conveying system, so the conveying pipes at the beginning have the highest frequency of frictional contact with the bar, resulting in the most residual scale and other impurities inside the pipes, which are most likely to scratch the wire surface. Similarly, the end of the conveying process after wire forming also guides the wire; if the conveying is not smooth here, it can lead to problems such as wire bending.

[0003] After searching, the existing technology announcement number CN222470237U is a spinning tube for a high-speed hot-rolled wire rod production line spinning machine. It provides a replacement solution for the spinning tube of the spinning machine and can reduce the vibration of the spinning tube itself and improve its service life.

[0004] The announcement number CN219786027U describes a wire feeding machine that prevents hot steel from hitting the inner wall of the tapered hole at the inlet nozzle of the wire feeding tube, allowing the hot steel to enter the wire feeding tube smoothly; thus avoiding the danger of hot steel getting stuck at the outlet of the guide tube or the inlet nozzle of the wire feeding tube.

[0005] Both of the above solutions address problems at the end of the cable transmission process; they do not address problems at the beginning of the transmission process.

[0006] Therefore, the applicant has provided a technical solution to address potential problems at the starting end of the transmission line, enabling quick and stable replacement of the conduit at the transmission starting end. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hot rolling device for improving the roundness of stainless steel wire. It can quickly and stably replace the pipe at the starting end of the pipe conveying mechanism through the pipe changing mechanism, thereby reducing the probability of wire scratches and damage to the roundness of the wire.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A hot continuous rolling apparatus for improving the roundness of stainless steel wire includes a tube changing mechanism, a pipeline conveying mechanism, and a finishing mill unit arranged in sequence. The finishing mill unit includes several finishing mills, each with a roll assembly. Cooling pipes are provided around the rolls, and spray nozzles are installed on the cooling pipes to spray water and cool the rolls. The cooling pipes are connected to an external water supply facility. The finishing mill is also equipped with a power shaft that drives the rolls to rotate, and the power shaft is connected to an external power supply device. The rolls roll the bar stock into wire.

The second clamp is used to install and fix the pipeline. One end of the pipeline is provided with a flared opening to facilitate the entry and transmission of the wire.

[0011] The pipe-changing mechanism is used to replace the pipe at the end of the pipe conveying mechanism. The pipe-changing mechanism includes a roller frame, a first U-shaped frame, an adjusting arm, a support frame, a limiting plate, an electric push rod, a support plate, a push rod, and a jacking mechanism. A support frame is provided at the bottom of the first U-shaped frame. A first clamp is fixed on one side of the first U-shaped frame to clamp the roller frame and ensure that the roller frame can rotate freely. To ensure smooth rotation of the roller frame, ball bearings are provided on the inner wall of the first clamp. The roller frame is provided with several limiting grooves and insertion holes. The number of limiting grooves and insertion holes is the same. The insertion holes are used to insert pipes. A central shaft is provided at one end of the roller frame. The central shaft is rotatably connected to the first U-shaped frame. Push blocks are provided on the end face of the roller frame. The number of push blocks is the same as the number of insertion holes. The push blocks, limiting grooves, and insertion holes are all evenly distributed.

[0012] The support plate is located on one side of the first U-shaped frame. A third U-shaped frame is located at one end of the support plate, and the third U-shaped frame and the support plate at the bottom are supported by a support frame. A fixing plate is located on the support plate, and a first rotating shaft is located on the fixing plate. A limiting frame is located at one end of the support plate, and a mounting plate is located at the other end. A sliding groove is provided on the limiting frame. The limiting plate is located on one side of the limiting frame, and a fixing block is located at the end of the limiting plate. A limiting frame is located on one side of the fixing block, and a slidably connected splined shaft is located within the limiting frame. One end of the splined shaft has a through shaft, which eliminates the drawbacks of through shaft rotation. The through shaft is slidably connected to the fixing block, and one end of the through shaft has a wedge. The device has a splined shaft with a second limiting plate inside a limiting frame. A second spring is sleeved on the splined shaft, contacting the inner wall of the limiting frame and the second limiting plate. A first guide shaft is slidably connected to a support plate at one end of a fixed block, and a first spring is sleeved on the first guide shaft, contacting the fixed block and the support plate. The limiting plate is L-shaped, with one end inside a limiting frame and a limiting shaft at the other end, located within a groove in the limiting frame. The combination of the limiting frame, the limiting shaft, and the first guide shaft ensures stable up-and-down sliding of the limiting plate.

[0013] One end of the adjusting arm is rotatably connected to the first rotating shaft, and one end of the adjusting arm is provided with a lever, which is located above the through shaft; one end of the adjusting arm is provided with a through groove, and the electric push rod is fixed on the third U-shaped frame. The top end of the electric push rod is provided with a second U-shaped frame, and the second U-shaped frame is provided with a fixed shaft, which is located in the through groove. The electric push rod drives the adjusting arm to rotate around the first rotating shaft as the axis.

[0014] The push rod has a second rotating shaft at one end, which is rotatably connected to the adjusting arm. The second rotating shaft is located on one side of the first rotating shaft. The top of the push rod has a push rod for pushing the push block.

[0015] The pushing mechanism is mounted on the mounting plate and includes an inclined top block that pushes a push rod. A second guide shaft and an insert plate are provided on one side of the top block. The insert plate is slidably connected to the mounting plate with the second guide shaft. The insert plate is located above the second guide shaft. A third spring is sleeved on the second guide shaft. The third spring pushes the mounting plate and the top block.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] During the conveying of bars and wires in the roller conveyor mechanism, the high-speed transmission of the wires leads to frequent contact with the inner wall of the pipe, resulting in wear, slag adhesion, or an uneven surface, which directly causes defects such as scratches on the wire surface. The pipe at the starting end of the conveying mechanism has the most frequent contact with the wires because it needs to guide the wires into the transmission steps, thus resulting in the most severe slag adhesion and steel buildup on the inner wall of the pipe. This technical solution addresses the above problems by providing a pipe-changing mechanism that can quickly and promptly replace the pipe at the starting end of the transmission, reducing the drawback of reduced wire roundness caused by slag accumulation scratching the wire surface.

[0018] During pipe replacement, the electric actuator pushes the adjusting arm to rise, which can both press the through shaft through the lever to release the limit plate from the roller frame, and push the push rod to push the push block to rotate the roller frame. The two are carried out in sequence to stably realize the rotation of the roller frame, pipe replacement, and the restriction and locking of the roller frame and pipe. This allows the pipe at the starting end to be replaced quickly. At the same time, the method of replacing pipe with roller frame is quick and stable, and it occupies a small area and is easy to install.

[0019] During application, the limiting plate, in conjunction with the limiting groove, can accurately limit and lock the roller frame to prevent rotation. Furthermore, because the number of insertion holes, push blocks, and limiting grooves are the same and evenly distributed, as shown in the attached diagram... Figure 7As shown, this ensures that the process of the limiting plate smoothly moving from leaving the limiting groove to re-entering the limiting groove and completing the replacement of the pipe position; thus, the technical solution described herein is stable, reliable, and highly efficient, and can operate normally even at high temperatures; it can provide strong assistance in improving and enhancing the roundness of wire rods during rolling.

The first U-shaped frame 12 is provided with a support frame 14 at its bottom, and a first clamp 121 is fixed on one side of the first U-shaped frame 12 to clamp the roller frame 11 and ensure that the roller frame 11 can rotate freely. To ensure that the roller frame 11 rotates smoothly in the first... A ball bearing is installed on the inner wall of a clamp 121. The roller frame 11 has several limiting grooves 111 and insertion holes 114, with the number of limiting grooves 111 and insertion holes 114 being the same.

A first spring 156 is provided on the first guide shaft 157, and the first spring 156 abuts against the fixing block 152 and the support plate 17; the limiting plate 15 is L-shaped, with one end of the limiting plate 15 located inside the limiting frame 173, and a limiting shaft 151 at one end of the limiting plate 15, which is located in the groove of the limiting frame; the limiting frame 173, in cooperation with the limiting shaft 151 and the first guide shaft 157, can ensure that the limiting plate 15 can slide stably up and down.

[0047] One end of the adjusting arm 13 is rotatably connected to the first rotating shaft 172. One end of the adjusting arm 13 is provided with a lever 131, which is located above the through shaft 153. One end of the adjusting arm 13 is provided with a through groove 132. The electric push rod 16 is fixed on the third U-shaped frame 174. The top end of the electric push rod 16 is provided with a second U-shaped frame 161. The second U-shaped frame 161 is provided with a fixed shaft 162, which is located in the through groove 132. The electric push rod 16 drives the adjusting arm 13 to rotate around the first rotating shaft 172.

[0048] The push rod 18 has a second rotating shaft 182 at one end, which is rotatably connected to the adjusting arm 13. The second rotating shaft 182 is located on one side of the first rotating shaft 172. The top of the push rod 18 has a push rod 181, which is used to push the push block 113.

The insert plate 193 is located above the second guide shaft 191. A third spring 192 is sleeved on the second guide shaft 191 and pushes the mounting plate 175 and the top block 194.

[0050] The tube replacement process is as follows:

[0051] When the pipe 4 at the starting end of the pipeline conveying mechanism 2 needs to be replaced, the transmission of the wire 5 is first stopped. Then, the adjusting arm 13 is pushed by the electric push rod 16 to rotate around the first rotating shaft 172. During this process, the lever 131 first touches the through shaft 153 and gradually presses down the through shaft 153 to make the limiting plate 15 disengage from the limiting groove 111. This process is completed before the push rod 181 contacts the push block 113. Then, the push rod 18 is continuously raised so that the push rod 181 contacts and pushes the push block 113, causing the roller frame 11 to rotate around the central axis 112. Then, under the continuous rotation, the lever 131 will disengage from the through shaft 153. During this process, the lever 131 disengages from the pressing through shaft 153 on the roller. After the frame 11 rotates, the limiting plate 15 is pushed out and pushed against the outer surface of the roller frame 11 by the first spring 156. The push rod 18 continues to rise and push the roller frame 11 to rotate. During the rotation, the limiting plate 15 will re-enter the limiting groove 111 when it matches the limiting groove 111 and restrict the rotation of the roller frame 11. At this time, the electric push rod 16 stops pushing out, thus completing the replacement of the pipe 4. Then the electric push rod 16 resets and retracts, pulling the push rod 18 down. The push rod 181 slides past the push block 113. At the same time, the push block 194, under the push of the third spring 192, ensures that the push rod 181 can always push against the side end face of the roller frame 11.

[0052] Further adjusting the lever 131 at the end of the arm 13 will push the wedge-shaped surface 1531 at the end of the shaft 153 in the opposite direction, thereby causing the shaft 153 to retract into the fixing block 152. After the lever 131 passes the shaft 153, the shaft 153 will be reset under the push of the second spring 158, making full preparation for the next replacement process. The pipe 4 can be replaced one by one according to the above process.
