Description

Technical Field

[0001] This invention relates to the field of metal wire processing technology, specifically to a metal wire for automotive piston rings and its processing technology. Background Technology

[0002] Piston rings are key components mounted on engine pistons. They are responsible for sealing the combustion chamber, conducting heat dissipation, and scraping off engine oil, directly determining the engine's sealing performance, power output, and compliance with exhaust emission standards.

[0003] With the continuous upgrading of national regulations and standards for motor vehicle exhaust emissions, the manufacturing precision and process complexity of automotive engine piston rings have increased significantly. The industry has also placed more stringent technical requirements on the surface appearance quality, forming accuracy, and stability of piston ring-specific wire. The forming and processing of piston ring wire mainly relies on two core processes: rolling and profile drawing. For conventional wires with simple structures, rolling is often sufficient to meet dimensional and forming requirements. For wires with complex irregular structures such as inverted tables, conical surfaces, and barrel surfaces, which are difficult to roll, profile drawing is the mainstream processing method to ensure the geometric dimensional accuracy and structural morphology of the finished product.

[0004] However, the above-mentioned conventional special-shaped drawing production method still has the following defects: during the production process, before the special-shaped drawing forming process, the oil stains, impurities and other contaminants on the surface of the wire substrate are not effectively treated, resulting in the appearance quality of the special-shaped wire being worse than that of the rolled wire. This is mainly manifested in the heavy oil stains on the wire surface, as well as the irregular dark oil stain color and the interlacing color difference between the metallic bright color, which affects the drawing quality. Summary of the Invention

[0005] The purpose of this invention is to provide a metal wire for automotive piston rings and its processing technology, in order to solve the problem that the oil stains, impurities and other contaminants on the surface of the wire substrate are not effectively treated before the conventional special-shaped drawing process, which affects the drawing quality.

[0009] Preferably, the rinsing component includes two sets of horizontal bars mounted above the rinsing tank, and two sets of parallel movable frames installed between the two sets of horizontal bars.

Below the movable frame are several arc-shaped plates for rinsing air bubbles from the metal wire, and the outer sides of the arc-shaped plates are provided with air-filling pipes for supplying gas to them.

[0010] Preferably, several arc-shaped plates located below the same movable frame are connected by multiple sets of through rods, and a top plate is installed at the end of the multiple sets of through rods. A rotating shaft is installed on the side wall of the top plate, and a vertical rod is installed on the end side wall of the movable frame. The bottom of the vertical rod is rotatably engaged with the rotating shaft.

[0011] Preferably, a gear is installed on the outer wall of the rotating shaft, a toothed plate is meshed with the outer side of the gear, the top of the toothed plate is fixedly connected to the moving frame through an electric push rod, and a guide sleeve for limiting the movement of the toothed plate is provided on the vertical rod.

[0012] Preferably, the output end of the arc-shaped plate is equipped with a plurality of nozzles, and the output ends of the nozzles are oriented toward the metal wire.

[0013] Preferably, the rinsing component includes a plurality of water-permeable holes formed on the side walls of both sides of the rinsing pool, and an arc-shaped groove is formed on the inner wall of the rinsing pool between the water-permeable holes. A plurality of flushing pipes are arranged in an array inside the arc-shaped groove, and a main water pipe is installed on the top of the plurality of flushing pipes. The washing pool has a drain outlet at the bottom, and a blocking plate that is periodically opened is installed inside the drain outlet.

[0014] Preferably, the filter element includes a discharge pipe installed below the washing tank and communicating with the discharge port, a snap-fit ​​plate is fixedly installed on the bottom side wall of the discharge pipe, and a snap-fit ​​opening is provided on the bottom wall of the washing tank to be sealed and connected with the snap-fit ​​plate.

[0015] Preferably, a filter tank is installed on the support at the bottom of the cleaning tank, and a sewage discharge trough for conveying sewage is opened inside the filter tank. A removable filter screen is installed inside the sewage discharge trough, and a docking interface for connecting with the discharge pipe is installed on the top of the filter tank.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. This invention achieves flexible adjustment of the lateral spacing between the two curved plates by setting up a spacing adjustment structure composed of a cylinder and a moving frame; by adding an angle adjustment transmission structure composed of an electric push rod, a toothed plate and gears, it achieves multi-angle posture adaptive fine adjustment of the curved plates, which can fit the contours of irregular wires with inverted platforms, conical surfaces and barrel surfaces, avoiding cleaning dead corners. At the same time, by integrating an air-filled tube tree and an array of nozzles inside the curved plates, it achieves the function of continuous underwater air generation and bubble bursting impact cleaning, removing oil and impurities from the wire surface without damaging the wire substrate. In addition, by combining a separate diversion structure of a washing tank and an oil tank, it achieves the function of collecting light oil overflow and separating large particle impurities by gravity sedimentation, improving the cleaning cleanliness of the wire substrate, and effectively improving the versatility of the equipment and the overall processing quality of the wire body.

[0017] 2. In this invention, a reverse flushing structure consisting of a main water pipe, flushing pipes, an arc-shaped groove, and permeable holes is added to the side wall of the washing pool. The water source is connected to the main water pipe and distributed to each group of flushing pipes. The water is then collected by the arc-shaped groove and sprayed outward from the permeable holes. This achieves normalized reverse flushing of the seepage area, promptly washing away the accumulated impurities and preventing blockage at the seepage point from the root.

[0018] 3. This invention adds a connecting discharge pipe to the bottom of the washing tank and equips it with a filter tank assembly with a built-in detachable filter screen. It is specifically designed to collect and filter out large particulate impurities deposited at the bottom of the tank. This allows for the timely removal and filtration of heavy impurities accumulated at the bottom of the washing tank, effectively reducing the accumulation of impurities in the tank, maintaining the cleanliness of the cleaning water, and preventing the turbidity of the wastewater from affecting the cleaning quality. At the same time, the detachable filter screen structure is easy to install and remove, facilitating daily cleaning and maintenance, and enabling the wastewater purification and recycling, further improving the overall practicality and cleaning stability of the equipment.

[0035] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0036] In Example 1, during the actual production of metal wire, before the special-shaped drawing process, the oil stains, impurities and other contaminants on the surface of the wire substrate were not effectively treated, resulting in the appearance quality of the drawn wire being worse than that of the rolled wire. This was mainly manifested in the heavy oil stains on the wire surface, as well as the irregular dark oil stain color and the intermingling of bright metallic color.

[0037] like Figures 1 to 6 In this embodiment, a metal wire for automotive piston rings includes a wire body, the base material of the wire body is an iron-based alloy, and the cross-section of the wire body is an irregular cross-section used to manufacture the top ring, second compression ring, or oil ring of automotive piston rings.

[0038] A processing method for manufacturing metal wire for automotive piston rings includes the following steps: S1. Cleaning treatment: The wire substrate is sent into the cleaning device for cleaning to remove oil and oxidation impurities from the surface of the wire. S2. Drawing: The cleaned wire substrate is processed by drawing to form a wire body with a special cross-sectional structure that is adapted to automotive piston rings.

[0039] A cleaning device for implementing the above-mentioned processing technology includes a cleaning tank 1 and a cleaning assembly 3 installed above the cleaning tank 1 for cleaning wire substrates; the cleaning assembly 3 includes a permeable rinsing tank 31, a rinsing component 32, a filter component 33 and a guide component 34. The rinsing tank 31 is equipped with a rinsing component 32 for rinsing the metal wire around the air bubbles, and both ends of the rinsing component 32 are provided with guide components 34 for adaptive limiting and guiding of the metal wire.

[0040] The rinsing component 32 includes two sets of horizontal bars 3214 mounted above the washing tank 31. Two sets of parallel movable frames 321 are slidably installed between the two sets of horizontal bars 3214. The side wall of the movable frame 321 is provided with a cylinder 322 to drive it to move horizontally. Below the movable frame 321 are several arc-shaped plates 323 for rinsing air bubbles from metal wires. The outer side of the several arc-shaped plates 323 is provided with an air-filling pipe 324 for supplying gas to them. Thus, the horizontal bars 3214 play a role in limiting the sliding movement of the two sets of movable frames 321, ensuring the stability of the two horizontal bars 3214 during movement. The output end of the arc plate 323 is equipped with several nozzles, and the output ends of the nozzles are set towards the wire substrate.

[0041] An inflation manifold 325 is provided on the outside of the inflation manifold 324 for uniformly inflating the branches of the inflation manifold 324.

[0042] Several arc-shaped plates 323 located below the same movable frame 321 are connected by multiple sets of through rods 326. The ends of the multiple sets of through rods 326 are all equipped with a top plate 327. A rotating shaft 3211 is installed on the side wall of the top plate 327. A vertical rod 3213 is installed on the end side wall of the movable frame 321. The bottom of the vertical rod 3213 is rotatably engaged with the rotating shaft 3211.

[0043] A gear 3212 is installed on the outer wall of the rotating shaft 3211. A toothed plate 329 is meshed with the outer side of the gear 3212. The top of the toothed plate 329 is fixedly connected to the moving frame 321 via an electric push rod 328. A guide sleeve 3210 is provided on the vertical rod 3213 to limit the movement of the toothed plate 329.

[0044] The working principle of cleaning oil and impurities from the surface of the wire body: Figures 1-6 Before the cleaning operation, the cleaning tank 1 is filled with cleaning water, and the water level completely submerges the arc plate 323. For irregular wire substrates with different cross-sectional shapes and different external structures, the posture of the arc plates 323 on both sides can be adjusted by a two-dimensional adjustment method to make them accurately fit the wire substrate (i.e. the raw material wire produced by the wire body) to ensure the cleaning fit and cleaning effect. First, adjust the spacing of the arc plates 323: Based on the horizontal cross-sectional diameter of the wire substrate, control the extension end of the cylinders 322 on both sides to extend and retract, which drives the moving frame 321 to move inward or outward synchronously. During the movement, the vertical rod 3213 and the rotating shaft 3211 move synchronously with the moving frame 321, which can adjust the relative spacing of the two sets of arc plates 323 so that the wire substrate is in the center position of the arc plates 323 on both sides, and achieves alignment and adaptation. Next, the angle of the curved plate 323 is adjusted: After the spacing is adjusted, based on the irregular outer contour of the wire substrate, the extension and retraction of the electric push rod 328 is controlled. Taking the extension action as an example, the electric push rod 328 pushes the toothed plate 329 downward. Through the meshing transmission between the toothed plate 329 and the gear 3212, the rotating shaft 3211 is driven to rotate, thereby driving multiple sets of curved plates 323 on the same side to rotate synchronously. This adapts to the special structures of irregular wires, such as curved surfaces, conical surfaces, and inverted platforms, allowing the curved plate 323 to completely conform to the shape of the wire, providing a structural basis for all-round cleaning. (Reference) Figures 12-15 The state diagram shown; After the posture adaptation adjustment is completed, routine cleaning operations can be carried out: During the operation, air is continuously supplied to the air pipe tree 324 through the air main pipe 325. After the gas enters the internal cavity of the arc plate 323, it is sprayed out at high speed through multiple sets of nozzles evenly arranged above the arc plate 323, forming a large number of fine bubbles inside the cleaning water. The bubbles continuously float to the surface of the wire substrate and burst. The impact energy generated by the bursting of the bubbles is used to peel off the stubborn oil and fine impurities attached to the surface of the wire substrate, achieving efficient cleaning of the surface of the wire substrate. The waste generated during cleaning can be separated and collected in layers: incompletely burst air bubbles carry light oil stains that have peeled off the surface of the wire substrate and float to the surface of the cleaning water. They then overflow through the grooves on both sides of the washing tank 31 and are discharged into the oil stain tank 2 for centralized treatment. Meanwhile, large particles of impurities that have fallen off the surface of the wire substrate settle naturally under the influence of gravity and accumulate at the bottom of the washing tank 31. This device can adapt to the shape and structure of various irregular wire substrates through bidirectional adaptive adjustment of the spacing and angle, achieving thorough cleaning of the wire substrate surface without dead angles. This solves the problem of incomplete cleaning by traditional cleaning methods and improves the cleaning quality of oil stains and impurities on the surface of the wire substrate.

[0045] It should be emphasized that the core improvement of this embodiment lies in: by setting a spacing adjustment structure composed of cylinder 322 and moving frame 321, the lateral spacing of the two arc plates 323 on both sides can be flexibly adjusted; by adding an angle adjustment transmission structure composed of electric push rod 328, toothed plate 329 and gear 3212, the arc plate 323 can be made adaptively fine-tuned in multiple angles, which can fit the contour of irregular wires with inverted platform, conical surface and barrel surface, avoiding cleaning dead corners; at the same time, by integrating air inflatable tube tree 324 and array nozzle structure inside the arc plate 323, the underwater continuous air generation and bubble burst impact cleaning function can be realized, stripping oil and impurities from the wire surface without damaging the wire substrate; in addition, by combining the washing tank 31 and oil tank 2 with a split diversion structure, the functions of light oil overflow collection and large particle impurity gravity sedimentation and stratification separation can be realized, improving the cleaning cleanliness of the wire substrate and effectively improving the equipment versatility and the overall processing quality of the wire body.

[0046] It should be noted that, such as Figures 1-2 , Figure 11Oil sludge tanks 2 are symmetrically installed on both sides of the cleaning tank 1. Grooves are provided on the side walls of the cleaning tank 1 opposite to the oil sludge tanks 2, and arc-shaped guide plates are provided on the grooves to guide the oil sludge.

[0047] like Figures 1 to 4 , Figure 8 In this embodiment, the guide member 34 includes a vertical frame 342 fixedly connected to the end of the movable frame 321. A diagonal rod 344 is fixedly connected to the bottom of the vertical frame 342. Both ends of the diagonal rod 344 are provided with annular plates 343. A guide wheel 341 for guiding the wire body is slidably provided between the two sets of annular plates 343. A limiting strip 345 is provided on the guide wheel 341 to limit the sliding of the annular plates 343. During the movement of the two sets of movable frames 321, the vertical frame 342 synchronously drives the two diagonal rods 344 to move, so that the two annular plates 343 move closer or further away from each other as the movable frame 321 moves. During the movement, the limit strip 345 limits the movement, achieving stable movement. This ensures stable guidance of the wire body. That is, the two annular plates 343 on the guide wheel 341 can synchronously complete the spacing adjustment with the movable frame 321, adapting to the conveying and guiding of wire bodies of different specifications and types, and has stronger versatility.

[0048] In Example 2, it is understood that in Example 1, the water in the cleaning tank 1 is circulated and replenished through the permeable rinsing tank 31. However, during continuous cleaning, impurities peeled off from the surface of the wire substrate are prone to accumulate and adhere to the permeable area above the rinsing tank 31. Long-term accumulation can easily cause blockage in the permeable area. After the permeable area is blocked, it directly affects the normal flow of water between the cleaning tank 1 and the rinsing tank 31, causing the water level in the tank to be unable to maintain the standard working level. Consequently, the cleaning water cannot completely submerge the arc plate 323, ultimately resulting in the nozzle of the arc plate 323 being exposed and the bubble cleaning effect failing, which seriously affects the overall cleaning quality and operational stability of the wire substrate. like Figure 1-3 to Figure 9-10 To solve the above problems, the rinsing component 32 includes a number of water-permeable holes 312 on the side walls of both sides of the washing pool 31. The inner wall of the washing pool 31 between the water-permeable holes 312 is provided with an arc-shaped groove 313. A number of flushing pipes 314 are arranged in an array inside the arc-shaped groove 313. The top of the number of flushing pipes 314 is connected to a main water pipe 311.

[0049] The washing pool 31 has a drain outlet 4 at the bottom, and a blocking plate that is periodically opened is installed inside the drain outlet 4.

[0050] The working principle of preventing blockage in the seepage area of ​​washing tank 31: Figure 10External cleaning water enters the interior of the flushing pipe 314 through the main water pipe 311. The cleaning water discharged through the flushing pipe 314 first flows into the interior of the arc-shaped groove 313, and then is discharged through several water-permeable holes 312 to back-flushing the water-permeable holes 312 in the seepage area, avoiding blockage in the seepage area, and ensuring the overall cleaning quality and operational stability of the wire substrate.

[0051] It should be emphasized that the core improvement of this embodiment is: a reverse flushing structure consisting of a main water pipe 311, a flushing pipe 314, an arc-shaped groove 313 and a permeable hole 312 is added to the side wall of the washing tank 31. The water source is connected to the main water pipe 311 and then distributed to each group of flushing pipes 314. The water is then collected by the arc-shaped groove 313 and sprayed outward from the permeable hole 312 to achieve normal reverse flushing of the seepage area, timely flushing off the accumulated impurities, and preventing the seepage location from becoming blocked from the root.

[0052] In Example 3, it is understood that although the added reverse flushing structure in Example 2 can clear the seepage area, ensure the stability of the water level inside the equipment, and meet the normal bubble cleaning operation requirements of the arc plate 323, in the actual cleaning operation, the bubbles carry light oil and fine scum to the surface of the water, while the large particles of heavy impurities peeled off from the surface of the wire substrate will continue to settle and accumulate at the bottom of the washing tank 31. The existing structure cannot effectively collect and orderly discharge the bottom deposited impurities. A large amount of sediment accumulates in the tank for a long time, continuously polluting the cleaning water, gradually reducing the cleanliness of the cleaning water, and weakening the subsequent cleaning effect of the wire substrate. like Figure 6 To solve the above problems, the filter element 33 includes a discharge pipe 335 installed below the washing tank 31 and connected to the discharge port 4. A snap-fit ​​plate 336 is fixedly installed on the bottom side wall of the discharge pipe 335, and a snap-fit ​​opening is provided on the bottom wall of the washing tank 1 to be sealed and connected to the snap-fit ​​plate 336.

[0053] A filter tank 331 is installed on the support at the bottom of the cleaning tank 1. The filter tank 331 has a sewage discharge trough 332 for conveying sewage. A removable filter screen 333 is installed inside the sewage discharge trough 332. The top of the filter tank 331 is equipped with a docking interface 334 that connects with the discharge pipe 335.

[0054] The working principle of this embodiment is as follows: During the operation, large particles of impurities that settle at the bottom of the washing tank 31 can be blocked by opening the four discharge ports, allowing the sediment and sewage to flow into the discharge pipe 335. The sewage is then transported through the discharge pipe 335 to the sewage discharge trough 332 inside the filter tank 331. When the sewage flows through the filter screen 333, the solid large particles of impurities are intercepted and isolated by the filter screen, completing the solid-liquid separation. The filtered and purified water can be recycled for cleaning. The staff can periodically disassemble the filter screen 333 to clean up the intercepted and accumulated impurities.

[0055] It should be emphasized that the core improvement of this embodiment is that a connecting discharge pipe 335 is added to the bottom of the washing tank 31, and a filter tank 331 assembly with a built-in detachable filter screen 333 is provided. A centralized collection and filtration discharge channel is specially set up for large particulate impurities deposited at the bottom of the tank. The heavy impurities accumulated at the bottom of the washing tank 31 can be discharged and filtered in a timely manner, effectively reducing the accumulation of impurities in the tank, maintaining the cleanliness of the cleaning water, and avoiding the impact of sewage turbidity on the cleaning quality. At the same time, the detachable filter screen structure is easy to disassemble and assemble, which is convenient for daily cleaning and maintenance, realizes the recycling of sewage purification, and further improves the overall practicality and cleaning stability of the equipment.

[0056] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
