Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed railway through-ground wire processing, and in particular relates to a rotating brush cleaning component. Background Art

[0002] The high-speed railway through-ground wire is mainly laid on both sides of the railway line and is used for grounding the railway signal system. It can keep the grounding potential between a large range of railway potentials basically consistent, making the grounding of system equipment safe and reliable.

[0003] The main core material of the high-speed rail through-ground wire is copper wire, which is produced by a solid-liquid composite continuous casting process. The process steps include: continuous casting, wire drawing and diameter reduction, annealing, and coiling. Among them, the copper wire enters the outer die at high temperature and rapid diameter reduction after the wire drawing process. During this process, the outer die oil needs to be used for cooling to prevent the copper wire from generating high temperature due to friction and causing the copper wire to break. Affected by the high temperature and the material of the oil, black oxide scale and some black oil residue will appear on the surface of the copper wire after it comes out of the mold mouth, resulting in poor surface condition of the copper wire. After the residual oil is annealed at high temperature, it will form carbonized residues on the surface of the copper wire, thus affecting the final surface quality of the through-ground wire.

[0004] At present, the method for domestic manufacturers of through-ground wires to remove oxide scale is to perform pickling and passivation treatment after wire drawing is completed. For example, Chinese patent application number CN202011572781.3 discloses a method for improving the surface treatment effect of copper busbars, including grinding, pickling and passivation, primary drying, screening, coating of protective agent, standing, cleaning, secondary drying, and packaging; the copper busbar obtained in S1 is immersed in a pickling and passivation solution with a composition of 20% nitric acid + 10% hydrofluoric acid + 70% water for full reaction and contact, so as to remove various grease, weld scars, oxide scale, etc. on the surface of the copper busbar.

[0005] However, the addition of pickling and passivation equipment increases capital investment on the one hand; on the other hand, the pickling and passivation process requires the use of strong acid and a passivating agent containing chromium compounds, which makes the entire pickling and passivation process have certain risk factors and will bring serious environmental pollution problems to the enterprise.

[0013] Furthermore, when the fixed cover moves relative to the inner wall of the rotating body, the fixed cover forces the spring brush to shorten, so that the bristles contacting the metal wire become denser.

[0014] Furthermore, a chip removal hole is radially opened on the peripheral wall of the rotating body, and the chip removal hole is connected to the groove.

[0015] Furthermore, a step hole is provided in the groove, the step hole is connected to the second through hole, and the end of the spring brush cooperates with the step hole.

[0028] like Figure 1 - Figure 3 As shown, a rotary brush cleaning assembly of the utility model comprises a rotary body 1 with a cylindrical outer contour, a fixed cover 2, a spring brush 4 and a disc-shaped base 3.

[0029] Wherein, a groove 10 is provided inside the rotating body 1;

[0030] The fixed cover 2 is coaxially arranged on the side of the groove 10 and connected to the inner wall of the rotating body 1. A first through hole 21 for the metal wire 5 to pass through is opened at the center of the fixed cover 2;

[0031] A base 3 is provided on the side of the rotating body 1 away from the fixed cover 2. A second through hole 30 is opened at the center of the base 3. The metal wire 5 passes through the second through hole 30 into the base 3, passes through the groove 10, and passes through the first through hole 21 to exit the fixed cover 2.

[0032] Among them, a plurality of bristles 40 are wound inside the spring brush 4, and the spring brush 4 is installed in the groove 10. The end of the spring brush 4 abuts against the fixed cover 2. The installation of the spring brush 4 does not distinguish between the front and rear directions. After the spring brush 4 is installed in the groove 10, it is pressed by the fixed cover 2.

[0033] The spring brush 4 is made of metal brush wires as bristles 40, which are embedded in a galvanized iron bar or a stainless steel bar and wound into a spring shape by a machine to form a brush roller. In this embodiment, an inner-wound spring brush 4 is used. Figure 2 shown.

[0034] It should be noted that the metal wire 5 referred to in this embodiment can be alloy, copper or other metals. For the high-speed railway through-ground wire, this embodiment uses copper wire / line.

[0035] like Figure 3 As shown, in the specific implementation, the base 3 is fixed to the end of the wire drawing machine die 6 by inserting a bolt into the mounting hole 31, and the two are coaxially arranged. The required copper wire is led out from the wire drawing machine die 6, and after passing through the base 3, the spring brush 4 and the fixed cover 2, the head of the copper wire is connected to the wire drawing machine reel through the reducing die, and at one end of the wire drawing machine die 6 near the tail of the copper wire, a chip liquid injection port 60 is provided. Through the chip liquid injection port 60, the wire drawing machine die 6 drives the belt 71, driven by the motor 70, to drive this component to rotate together. After the motor 70 is started, the chip liquid starts to spray. Among them, when the copper wire is pulled forward, the spring brush 4 brushes away the oxide on the surface of the copper wire.

[0036] In addition to the original spray cooling function, the cutting fluid can also provide the necessary cleaning basic conditions for removing the oxidation residues on the surface of the copper wire of the spring brush 4.

[0037] The technical solution drives the assembly to rotate at high speed through the high-speed motor 70, and the spring brush 4 polishes the surface of the copper wire to remove oil, rust and oxidation stains from the surface of the copper wire. After the surface treatment, the copper wire is driven by the wire drawing machine reel into the outer mold, and a through-ground wire product with a clean and shiny surface is pulled out. No additional pickling process is required, reducing the possibility of environmental pollution.

[0038] In addition, this embodiment can generate different compression forces on the spring brush 4 by controlling the tightness of the fixed cover 2. When the fixed cover 2 moves relative to the inner wall of the rotating body 1, the fixed cover 2 forces the spring brush 4 to shorten, making the bristles 40 in contact with the metal wire 5 denser. Conversely, the length of the spring brush 4 is extended and the density of its bristles 40 is reduced.

[0039] According to the different oxidation quality of the copper wire, adjust the tightness of the spring brush 4. If the surface of the copper wire needs to be slightly polished, tighten the fixed cover 2 for 3 to 5 turns. If the surface of the copper wire is severely oxidized, fix the fixed cover 2 to the bottom. In this way, when the component is driven to rotate, the oxide scale on the surface of the copper wire can be removed.

[0040] Among them, the fixed cover 2 and the rotating body 1 can be connected by threaded connection. An adjusting protrusion 22 is provided at the end of the fixed cover 2. By using a tool to twist the adjusting protrusion 22, the fixed cover 2 is rotated and thus moves inside the rotating body 1. In addition, the adjusting protrusion 22 can be designed into an internal / external hexagonal form to facilitate the cooperation of commonly used tools, such as a hexagonal screwdriver, a wrench, etc.

[0041] In addition, the rotating body 1 has a chip removal hole 12 radially opened on the peripheral wall, and the chip removal hole 12 is connected to the groove 10. The copper wire is pulled forward and cleaned by the bristles 40 at the same time, and the oxide scale removed by the cleaning is discharged from the chip removal hole, preventing the oxide scale or chip liquid from being deposited in the groove 10 and affecting the cleaning effect of the spring brush 4.

[0042] The groove 10 is provided with a stepped hole 11, which is connected to the second through hole 30, and the end of the spring brush 4 is matched with the stepped hole 11. The stepped hole 11 is concentric with the first through hole 21 and the second through hole 30. The step hole 11 is provided to realize the penetration of the copper wire on the one hand, and to facilitate the installation of the spring brush 4 on the other hand, so that the copper wire coincides with the central axis of the spring brush 4.
