Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide structure technology, specifically a rolling guide structure for the export of copper rods produced by continuous rolling and casting. Background Technology
[0002] Continuous casting and rolling is a metal rolling process in which molten metal is poured into a continuous casting machine to cast a continuous casting billet, which is then held at a temperature in a soaking furnace for a certain period of time before being directly rolled into shape in a hot continuous rolling mill. It can be used to produce metal rods such as steel rods and copper rods.
[0003] During the rolling process of copper rods, guides, usually rolling guides, are installed before and after the roll pass. These guides ensure the workpiece is correctly guided into the roll pass and smoothly exited, preventing roll entanglement. Most commonly available rolling guides on the market share a similar overall structure, with a steel outer shell, a cylindrical guide on the feed side, and two sets of guide rolls on the discharge side. However, they have some functional shortcomings in actual use and have room for improvement. For example, current rolling guides typically cool the rolls from top to bottom, while the rolls are in contact with the metal billet from the side. Top cooling can easily cause a large temperature difference between the top and bottom of the roll, resulting in poor cooling effect and a certain probability of roll deformation and cracking. They also lack the function of uniformly cooling the rolls.
[0004] Now, a novel rolling guide structure for the export of copper rods produced by continuous rolling and casting is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a rolling guide structure for the exit of copper rod continuous rolling and casting production, so as to solve the problem mentioned in the background art of not having the function of uniformly cooling the rollers.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rolling guide structure for the exit of a copper rod continuous rolling and casting production line, comprising a bottom fixing frame, a top fixing seat fixedly connected to the top of the bottom fixing frame, a feed guide cylinder fixedly connected to the right side of the top fixing seat, roller fixing frames fixedly connected to the front and rear ends of the top fixing seat, a roller mounting groove provided on the left side of the roller fixing frame, a guide roller movably connected between the upper and lower ends inside the roller mounting groove, a PLC controller installed at the front end of the top fixing seat, a water receiving tray provided below the guide roller, two sets of drain pipes welded to the bottom end of the water receiving tray, and a cooling component for uniformly and rapidly cooling the rollers provided inside the roller mounting groove.
[0007] The cooling assembly includes an arc-shaped hollow shell, which is fixedly connected to the right side inside the roller mounting groove. A cooling water inlet pipe is fixedly connected to the top of the arc-shaped hollow shell, and multiple sets of water outlet holes are opened on the left side of the arc-shaped hollow shell.
[0008] As a further technical solution of this utility model, the cooling water inlet pipe and the interior of the arc-shaped hollow shell are connected, and the shape and size of the left side of the arc-shaped hollow shell are adapted to the shape and size of the right side of the guide roller.
[0009] As a further technical solution of this utility model, there is a distance between the arc-shaped hollow shell and the guide roller, and the water outlet holes are arranged at equal intervals.
[0010] As a further technical solution of this utility model, the top of the water receiving tray is lower than the bottom of the roller fixing frame, and the bottom of the water receiving tray and the top of the bottom fixing frame are fixedly connected.
[0011] As a further technical solution of this utility model, the water receiving tray and the drain pipe are internally connected, and the drain pipe is symmetrically distributed about the vertical center line of the water receiving tray.
[0012] As a further technical solution of this utility model, electric cylinders are fixedly connected to the upper and lower ends of the feeding guide cylinder, and a concave frame is fixedly connected to the output end of the electric cylinder. An adjusting roller is movably connected between the front and rear ends inside the concave frame. The adjusting rollers are symmetrically distributed about the horizontal center line of the feeding guide cylinder. The electric cylinder and the PLC controller are electrically connected.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the copper rod continuous rolling and casting production outlet rolling guide structure not only realizes the function of uniform cooling of the roller parts, but also realizes the function of receiving and guiding wastewater, and also realizes the function of guiding billets;
[0014] The system is equipped with a cooling water inlet pipe, an arc-shaped hollow shell, and a water outlet. During use, the rolled copper rod billet enters from the feed guide cylinder, passes through the feed guide cylinder, and then passes between two sets of guide rollers. The two sets of guide rollers ensure stable deformation of the rolled piece in the die and achieve the required geometric shape and size. The cooling water is pumped into the arc-shaped hollow shell along the cooling water inlet pipe. The arc shape of the side of the arc-shaped hollow shell matches the shape of the guide rollers. The cooling water is evenly sprayed onto the side of the guide rollers along the water outlet. As the guide rollers rotate, their surface can be evenly cooled to prevent uneven heating and achieve the function of uniform cooling of the rollers.
[0015] With a water receiving tray and a drain pipe, when in use, cooling water is sprayed onto the guide rollers. Some of it evaporates due to heat, while some flows downwards. The water receiving tray collects the dripping cooling water and then discharges it outwards from the drain pipe, thus realizing the function of receiving and guiding wastewater.
[0016] Equipped with an electric cylinder, a concave frame, and an adjusting roller, the rolled copper rod billet enters from the feed guide cylinder during use. Depending on the height of the exit position of the rolling roll, if the billet head is low during the initial guiding of the copper rod billet head, the bottom electric cylinder is activated, extending slightly upwards. The adjusting roller then lifts the billet head. If the billet head is initially high, the higher electric cylinder is activated, aligning the billet head with the center of the feed guide cylinder, thus achieving the function of guiding the billet.

[0024] Please see Figure 1-4 A continuous rolling and casting production export rolling guide structure for copper rods also includes a cooling component. The cooling component includes an arc-shaped hollow shell 6, which is fixedly connected to the right side inside the roller mounting groove 8. A cooling water inlet pipe 5 is fixedly connected to the top of the arc-shaped hollow shell 6, and multiple sets of water outlet holes 7 are opened on the left side of the arc-shaped hollow shell 6.
[0025] The cooling water inlet pipe 5 and the interior of the arc-shaped hollow shell 6 are connected. The shape and size of the left side of the arc-shaped hollow shell 6 are matched with the shape and size of the right side of the guide roller 9. There is a distance between the arc-shaped hollow shell 6 and the guide roller 9. The water outlet holes 7 are arranged at equal intervals to cool the rollers evenly.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, cooling water is pumped by the pump and enters the arc-shaped hollow shell 6 through the cooling water inlet pipe 5. The arc shape of the side of the arc-shaped hollow shell 6 matches the shape of the guide roller 9. The cooling water is evenly sprayed on the side of the guide roller 9 through the water outlet hole 7. As the guide roller 9 rotates, its surface can be cooled evenly to prevent uneven heating.
[0027] A water receiving tray 10 is provided below the guide roller 9. Two sets of drain pipes 11 are welded to the bottom end of the water receiving tray 10. The top end of the water receiving tray 10 is lower than the bottom end of the roller fixing frame 4. The bottom end of the water receiving tray 10 is fixedly connected to the top end of the bottom fixing frame 1. The water receiving tray 10 and the drain pipes 11 are internally connected. The drain pipes 11 are symmetrically distributed about the vertical center line of the water receiving tray 10 and can collect wastewater.
[0028] Specifically, such as Figure 1 and Figure 3 As shown, the water receiving tray 10 collects the dripping cooling water and discharges it outward from the drain pipe 11.
[0029] Electric cylinders 12 are fixedly connected to the upper and lower ends of the feed guide cylinder 2, and concave frame 13 is fixedly connected to the output end of the electric cylinder 12. Adjusting rollers 14 are movably connected between the front and rear ends inside the concave frame 13. The adjusting rollers 14 are symmetrically distributed about the horizontal center line of the feed guide cylinder 2. The electric cylinder 12 and PLC controller 15 are electrically connected to facilitate the guidance of the billet head.
[0030] Specifically, such as Figure 1 and Figure 4 As shown, if the billet head is low, the bottom electric cylinder 12 is activated, and the electric cylinder 12 extends upward slightly to lift the billet head through the adjusting roller 14. If the billet head is initially high, the high electric cylinder 12 is activated to align the billet head with the center of the feed guide cylinder 2. The electric cylinder 12 and the PLC controller 15 are electrically connected. This technology is existing technology and will not be described in detail.
[0031] The computer software involved in the PLC controller and other hardware carriers in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.
[0032] Therefore, the "PLC controller" and "electric cylinder" mentioned in this application are all physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the rolling guide of this application, so as to solve the corresponding technical problems to be solved by this application.
[0033] Working Principle: In use, the rolled copper rod billet first enters through the feed guide cylinder 2, passes through the feed guide cylinder 2, and then passes between two sets of guide rollers 9. The two sets of guide rollers 9 ensure stable deformation of the rolled workpiece in the die, achieving the required geometric shape and size. Cooling water, transported by a pump, enters the arc-shaped hollow shell 6 along the cooling water inlet pipe 5. The arc shape of the side of the arc-shaped hollow shell 6 matches the shape of the guide rollers 9. The cooling water is evenly sprayed onto the side of the guide rollers 9 along the outlet holes 7. As the guide rollers 9 rotate, their surface is evenly cooled, preventing uneven heating. Part of the cooling water sprayed onto the guide rollers 9 evaporates due to heat, while some flows downwards. The water receiving tray 10 collects the dripping cooling water and discharges it outwards through the drain pipe 11. The rolled copper rod billet enters from the feed guide cylinder 2. Depending on the height of the rolling roll exit position, when guiding the copper rod billet head in the early stage, if the billet head is low, the bottom electric cylinder 12 is activated. The electric cylinder 12 extends upward slightly and lifts the billet head through the adjusting roller 14. If the billet head is high in the early stage, the high electric cylinder 12 is activated to make the billet head aligned with the center position of the feed guide cylinder 2.
