Description

Technical Field

[0001] This invention relates to the field of copper-clad steel production technology using horizontal continuous casting process, specifically to a straightening system and a copper-clad steel production line having the same. Background Technology

[0002] Copper-clad steel bimetallic composite material, also known as copper-clad steel, is a composite conductor made of copper and steel through a special process. This composite conductor has both the high strength, excellent elasticity, large thermal resistance and high magnetic permeability of steel, and the good electrical conductivity and excellent corrosion resistance of copper. It is widely used in many fields such as electrical and electronic industries.

[0003] Currently, there are three main methods for copper plating on steel wire in China (electroplating, cladding, and horizontal continuous casting cladding). Among them, horizontal continuous casting cladding solves the problems of thin copper layers in electroplating and poor bonding in cladding, making it a commonly used production method by domestic manufacturers. The production process of horizontal continuous casting cladding includes steel wire pretreatment, copper melting, crystallization, and post-treatment. In the existing pretreatment processes, straightening and cooling are crucial components. The steel wire may oscillate up and down between the straightening machine and the traction device due to gravity or insufficient synchronization between the two. Furthermore, the oscillation amplitude may exceed the normal and safe range due to wire breakage in the copper melting furnace or mechanical damage to the crystallizer, thus affecting the dimensional accuracy of the copper-clad steel product. In actual production, manufacturers often neglect to monitor the steel wire oscillation amplitude, failing to detect deviations from the normal range in a timely manner, thus affecting the accuracy of the copper-clad steel product. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art where the steel wire swing amplitude is ignored during the transmission between the straightening machine and the traction device, and the steel wire swing amplitude exceeds the normal range in a timely manner, thus affecting the dimensional accuracy of copper-clad steel products. The present invention provides a straightening system and a copper-clad steel production line having the same.

[0005] To address the above problems, the present invention provides a calibration system, comprising:

[0006] A straightening structure, wherein the straightening structure is provided with a discharge port for the steel wire to extend out;

[0007] The traction device is provided with an inlet that allows the steel wire to enter;

[0008] An early warning structure is provided between the straightening structure and the traction device. The early warning structure is provided with at least one monitoring rod. The monitoring rod has a warning area on its peripheral wall. The warning area is adapted to rub against the steel wire when the steel wire swings, so as to indicate the swing range of the steel wire.

[0009] Optionally, the warning area is coated with a pigment layer or provided with a display layer.

[0010] Optionally, the pigment layer is lime powder.

[0011] Optionally, the monitoring rod extends vertically toward the steel wire with a safety rod, which is positioned outside the normal swing range of the steel wire.

[0012] Optionally, the safety bar is slidably connected to the monitoring bar.

[0013] Optionally, the safety bar is connected to the control backend signal.

[0014] Optionally, the straightening structure further includes a rotary straightener, which includes a rotating base and at least one straightening ring. The straightening ring is fixedly disposed within the rotating base and has a straightening hole that allows the steel wire to pass through.

[0015] Optionally, the rotating seat has an adjusting plate on at least one side in the radial direction, the adjusting plate having a through hole that allows an adjusting rod to pass through, the adjusting rod passing through the through hole and abutting against the side of the straightening ring.

[0016] Optionally, the rotating seat has an inlet and an outlet, and both the inlet and outlet are conical openings.

[0017] A copper-clad steel production line includes the aforementioned straightening system.

[0018] The technical solution of this invention has the following advantages:

[0019] 1. The straightening system provided by this invention includes: a straightening structure, which has a discharge port for steel wire extension; a traction device, which has an inlet for allowing steel wire to enter; and an early warning structure located between the straightening structure and the traction device. The early warning structure has at least one monitoring rod, and a warning area is provided on the peripheral wall of the monitoring rod. The warning area is adapted to rub against the steel wire when it swings, so as to indicate the swing range of the steel wire. In actual production, the steel wire enters the inlet of the traction device through the discharge port of the straightening structure. The steel wire swings up and down between the straightening structure and the traction device due to gravity or other factors. During the swing, the steel wire will rub against the warning area of ​​the monitoring rod. The warning area is used to indicate the swing range of the steel wire, so as to stop the production of copper-clad steel in time when the steel wire exceeds the normal and safe swing amplitude, eliminate potential hidden dangers in production, and ensure that the dimensional accuracy of the copper-clad steel product meets the quality standards.

[0020] 2. The alignment system provided by this invention has a warning area coated with a pigment layer or a display layer, where the pigment layer is lime powder. When the warning area is coated with a pigment layer, the steel wire will wipe away the pigment layer when rubbing against the monitoring rod. The operator only needs to observe the location of the pigment in the warning area to determine whether the swing of the steel wire is within the safe range. When the warning area is a display layer, the steel wire has an oxide layer formed due to long-term contact with air. When the steel wire rubs against the monitoring rod, the oxide will be applied to the display layer. The operator only needs to observe the location of the oxide in the warning area to determine whether the swing of the steel wire is within the safe range.

[0021] 3. The straightening system provided by this invention has a monitoring rod extending vertically towards the steel wire, with a safety rod positioned outside the normal swing amplitude of the steel wire. The safety rod is connected to the control backend signal. When the safety rod contacts the steel wire, it indicates that the steel wire swing amplitude is outside the normal swing amplitude, and the signal is then transmitted to the backend control personnel to achieve real-time monitoring of the steel wire swing amplitude. This increases the means of steel wire swing amplitude monitoring and further improves the accuracy of monitoring.

[0022] 4. The straightening system provided by this invention has a sliding connection between the safety rod and the monitoring rod to accommodate steel wires of different diameters, thereby enhancing the applicability of the straightening system.

[0023] 5. The straightening system provided by the present invention includes a rotary straightener, which comprises a rotating base and at least one straightening ring. The straightening ring is fixedly disposed within the rotating base and has a straightening hole that allows a steel wire to pass through. When the steel wire is located within the straightening hole, the rotating base rotates, causing the straightening ring to perform a circular motion, thereby rotating the straightening hole to straighten the steel wire and achieving the straightening of the steel wire.

[0024] 6. The straightening system provided by the present invention has an adjusting plate on at least one side of the rotating seat along the radial direction. The adjusting plate has a through hole that allows an adjusting rod to pass through. After passing through the through hole, the adjusting rod abuts against the side of the straightening ring. When a bend occurs at a certain position in the rotary straightener, the adjusting rod abuts against the side of the straightening ring at that position. Through the cooperation of the adjusting plate and the adjusting rod, the adjusting rod applies a certain force to the straightening ring, straightening the bend by means of force, thereby limiting the steel wire and achieving the straightening effect.

[0025] 7. The straightening system provided by the present invention has a rotary seat with an inlet and an outlet, both of which are conical openings. The conical opening design can remove impurities attached to the steel wire. Attached Figure Description

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1 - Figure 3 One specific implementation of the straightening system shown includes: a steel wire 2 extending from the feeding structure passes sequentially through a straightening structure, an early warning structure 3, and a traction device 1 arranged in sequence, wherein there is a certain distance between the straightening structure, the early warning structure 3, and the traction device 1.

[0036] like Figure 1 , Figure 3 As shown, the straightening structure includes a horizontal straightener 6, a rotary straightener 5, and a vertical straightener 4 arranged sequentially to straighten the steel wire 2 passing through it in different directions. The rotary straightener 5 includes a rotating base 10 and multiple straightening rings 12 spaced apart along the axial direction of the rotating base 10. One side of the straightening ring 12 is engaged with the rotating base 10 to achieve modular installation. To facilitate the passage of the steel wire 2, each straightening ring 12 has a straightening hole with a diameter slightly larger than the diameter of the steel wire 2. To facilitate adjustment of the bending position on the steel wire 2, the rotating base 10 has adjusting plates 13 on both radial sides, corresponding to the straightening rings 12. The adjusting plates 13 have through holes that allow the adjusting rod to pass through. After passing through the through holes, the adjusting rod abuts against the outer side of the straightening ring 12. Specifically, the adjusting rod is a screw, and the through hole of the adjusting plate 13 is an internally threaded hole adapted to the screw. To facilitate the entry and exit of the steel wire 2, the rotating seat 10 has an inlet channel 9 and an outlet channel 11, both of which are conical openings.

[0037] like Figure 2 As shown, to monitor the swing vibration of the steel wire 2 between the straightening structure and the traction device 1, the early warning structure 3 is a frame. A monitoring rod 7 is provided at the edge of the frame, and a warning area is provided on the periphery of the monitoring rod 7. The warning area is coated with a pigment layer, specifically lime powder. To prevent excessive swing of the steel wire 2, a safety rod 8 extends vertically from the monitoring rod 7 towards the steel wire 2. The safety rod 8 is located outside the normal swing amplitude of the steel wire 2 and is slidably connected to the monitoring rod 7. To facilitate real-time monitoring of the swing amplitude of the steel wire 2, the safety rod 8 is connected to the control backend signal.

[0038] In the specific implementation process, the steel wire 2 conveyed by the feeding mechanism passes sequentially through the horizontal straightener 6, the rotary straightener 5, the vertical straightener 4, and the traction device 1. Due to the certain gap between the vertical straightener 4 and the traction device 1, the steel wire 2 will sway due to gravity or other factors. The monitoring rod 7 of the early warning structure 3 has a warning zone on its periphery. This warning zone is designed to rub against the steel wire 2 during swaying. During this friction, the steel wire 2 will come into contact with the pigment layer, leaving a mark on the warning layer. Workers only need to observe the mark on the steel wire 2 to determine whether the sway amplitude exceeds the normal and safe sway range. If the sway amplitude of the steel wire 2 exceeds the normal and safe sway range, the steel wire 2 will collide with the safety rod 8. The safety rod 8 will promptly transmit the collision signal to the control backend, and workers will immediately stop production, check the cause of the excessive sway amplitude of the steel wire 2, and eliminate any potential safety hazards.

[0039] A copper-clad steel production line is also provided, including the aforementioned straightening system.

[0040] The straightening system provided by this invention can adapt to steel wires 2 of different lengths and diameters, and has the advantages of wide applicability, strong practicality and high monitoring accuracy.

[0041] As an alternative implementation, the straightening ring 12 can also be fixedly connected to the rotating seat 10.

[0042] As an alternative implementation, the warning area may also be provided with a display layer that can display oxides on the steel wire 2.

[0043] As an alternative implementation, lime powder is provided on the opposing peripheral walls of the two adjacent monitoring rods 7 of the early warning structure 3, the distance between the two monitoring rods 7 is slightly larger than the diameter of the steel wire 2, and the steel wire 2 passes through the gap between the two monitoring rods 7 to further improve the accuracy of monitoring.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
