Description

Technical Field

[0001] This utility model relates to the field of cored wire production technology, specifically to an oiling device for cored wire production. Background Technology

[0002] Cored wire is made by wrapping alloy powder around a strip of steel. Depending on the alloy powder, cored wire can be divided into silicon-calcium-barium wire, barium-aluminum wire, calcium-iron wire, etc. The appearance of cored wire is similar to that of a coil. Types of cored wire include pure calcium wire, silicon-calcium wire, aluminum-calcium wire, rare earth wire, titanium-iron wire, etc. In the production process of cored wire, the wound cored wire needs to be oiled.

[0003] A cored wire oiling device, with announcement number CN219024804U, belongs to the field of cored wire oiling. It includes a base plate, a mounting frame, a guide, an oiling component, and an oil scraping component. The mounting frame is mounted on the base plate, and the guide is mounted on the mounting frame. The guide is used to transport and guide the cored wire during the oiling process. The oiling component, mounted on the mounting frame, is used to apply oil to the cored wire. The device uses a second and a third motor to drive two sets of rotating drums in opposite directions, causing two sets of belts to move in the same direction. This allows the two sets of belts to move and transport the cored wire without deviation.

[0004] This device uses an oiling cylinder to oil the cored wire. However, the oil utilization rate is low during the oiling process, and the oil scraper can only scrape oil from cored wires of the same diameter, which cannot meet the oiling needs of cored wires of various diameters. The oiling efficiency and quality are low. Therefore, it is necessary to design an oiling device for cored wire production that improves the oiling efficiency and quality. Utility Model Content

The fixed ends of the four hydraulic telescopic cylinders 2 are fixedly connected to the inner wall of the circular ring. The output ends of the hydraulic telescopic cylinders 2 face the center of the circular ring. Each output end of the hydraulic telescopic cylinder 2 is fixedly connected to an oil nozzle. The input pipe of the oil nozzle is connected to an oil pump. The input pipe of the oil pump is connected to an oil tank located within the workbench. An oil outlet is formed on the side of the circular ring near the oil collection groove.

[0010] The present invention further describes that the drying component includes a block, on which a drying cavity is formed. The drying cavity is coaxially arranged with the transmission center line of the cored wire. A plurality of air holes are formed on the inner wall of the drying cavity.

[0024] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-7 The present invention provides a technical solution: an oiling device for cored wire production, including a workbench 1. An oil spraying assembly 2, an oil scraping assembly 3, and a drying assembly 4 are arranged sequentially on the workbench 1 along the transmission direction of the cored wire. An oil collecting trough 5 is provided on the workbench 1, which is located directly below the oil spraying assembly 2 and the oil scraping assembly 3, and is used to collect the oil flowing down from the oil spraying assembly 2 and the oil scraping assembly 3.

[0026] Both sides of the workbench 1 along its length are fixedly connected to a connecting plate 6. The connecting plate 6 is horizontally set, and a hydraulic telescopic cylinder 7 is set on the connecting plate 6. The hydraulic telescopic cylinder 7 is vertically set, and the fixed end of the hydraulic telescopic cylinder 7 is fixedly connected to the connecting plate 6. The output end of the hydraulic telescopic cylinder 7 is fixedly connected to a bracket 32. A groove 8 is opened on the side of the bracket 32 ​​away from the hydraulic telescopic cylinder 7. A guide wheel 9 is rotatably connected in the groove 8. The guide wheel 9 is a "V" shaped roller.

[0027] The cored wire is placed on the guiding wheel 9 on one side of the workbench 1, and sequentially passes through the oil spraying component 2, the oil scraping component 3, and the drying component 4, and then is placed on the guiding wheel 9 on the other side of the workbench 1 and is wound and牵引 by the winding machine.

[0028] As Figure 2 , the oil spraying component 2 includes a first connecting frame 10. The first connecting frame 10 is in a "U" shape. The first connecting frame 10 is fixedly connected to the workbench 1. A second groove 11 is opened on the side of the first connecting frame 10 facing the workbench 1. The second groove 11 is arranged opposite to the oil collecting groove 5. A circular ring 12 is fixedly connected in the second groove 11. A plurality of second hydraulic telescopic cylinders 13 are arranged in the circular ring 12. In this embodiment, four second hydraulic telescopic cylinders 13 are provided. The four second hydraulic telescopic cylinders 13 are evenly distributed in a circle with the axis of the circular ring 12 as the center. The included angle between the four second hydraulic telescopic cylinders 13 and the vertical line of the center of the circular ring 12 is 45°.

[0029] The fixed ends of the four second hydraulic telescopic cylinders 13 are fixedly connected to the inner wall of the circular ring 12. The output ends of the second hydraulic telescopic cylinders 13 face the center of the circular ring 12. And the output end of each second hydraulic telescopic cylinder 13 is fixedly connected with an oil spraying nozzle 14. The input end of the oil spraying nozzle 14 is connected with an oil pump through a pipeline. The input end of the oil pump is connected with a fuel tank through a pipeline. The fuel tank is located inside the workbench 1.

[0030] The bottom side of the oil collecting groove 5 is connected to the fuel tank through a pipeline. A filter is fixedly connected to the input port of the oil collecting groove 5 connected to the fuel tank to filter impurities in the oil in the oil collecting groove 5.

[0031] The output ends of the four oil spraying nozzles 14 can all spray an oil spraying area in a 120° fan shape, so as to completely spray the cored wire passing through the center of the circular ring 12 with oil.

[0032] An oil outlet 15 is opened on the side of the circular ring 12 close to the oil collecting groove 5. The oil sprayed on the circular ring 12 by the oil spraying nozzle 14 flows into the oil collecting groove 5 through the oil outlet 15 under the action of gravity.

[0033] As Figure 3 , the oil scraping component 3 includes two second connecting plates 16. The second connecting plates 16 are in an "L" shape. The two second connecting plates 16 are symmetrically arranged with respect to the transmission line of the cored wire. The short plate sides of the two second connecting plates 16 face away from each other.

[0034] A connecting block 17 is fixedly connected between the two second connecting plates 16. A wire passing cavity 18 is opened on the connecting block 17. The wire passing cavity 18 is in a cylindrical structure. The wire passing cavity 18 is coaxial with the transmission line of the cored wire and is open at both ends along the axial direction.

[0035] The connecting block 17 has several grooves 19 along its length. The grooves 19 are arranged linearly and evenly along the length of the connecting block 17. The grooves 19 are connected to the wire passage cavity 18. Each groove 19 is slidably connected to a scraper 20. A connecting plate 21 is fixedly connected to the side of the scraper 20 away from the worktable 1. The connecting plate 21 is horizontally set. Hydraulic telescopic cylinders 22 are set at both ends of the connecting plate 21 along its length and on the side closer to the worktable 1. The hydraulic telescopic cylinders 22 are vertically set. The fixed end of the hydraulic telescopic cylinder 22 is fixedly connected to the connecting plate 16. The output end of the hydraulic telescopic cylinder 22 is fixedly connected to the connecting plate 21, so that the scraper 20 is driven to rise and fall along the groove 19 through the hydraulic telescopic cylinder 22.

[0036] Each scraper 20 has a wire-passing hole 23. The diameter of the wire-passing holes 23 on several scrapers 20 decreases sequentially along the transmission direction of the cored wire. The wire-passing holes 23 with the largest diameter correspond to the cored wires with the largest diameter. Each wire-passing hole 23 is fitted with a rubber ring of the corresponding diameter. Thus, according to the diameter of the cored wire being oiled, the scraper 20 with the wire-passing hole 23 of the corresponding diameter is controlled to descend, so that the wire-passing hole 23 is coaxial with the wire-passing cavity 18. The cored wire passes through the wire-passing hole 23, and the excess oil on the cored wire is scraped off by the rubber ring on the wire-passing hole 23. While reducing the wear of the cored wire, the elasticity of the rubber ring itself makes it fit the cored wire better, thereby improving the oil scraping effect on the cored wire.

[0037] like Figure 4 , Figure 5 Each wire passage hole 23 has an annular groove 24 on the side of its inner wall near the direction of core wire transmission. The cross-sectional shape of the annular groove 24 in its radial direction is trapezoidal. The inner diameter of the wire passage hole 23 relative to the side of the annular groove 24 near the transmission direction is larger than the diameter of the core wire passing through the scraper 20, so that the oil scraped off the core wire by the wire passage hole 23 flows into the annular groove 24.

[0038] like Figure 5 , Figure 6 An oil drain hole 25 is provided on the side of the annular groove 24 near the workbench 1. An oil drain nozzle 26 is fixedly connected to the scraper 20 corresponding to the oil drain hole 25. The oil drain nozzle 26 is a hollow cylinder with open ends. The oil drain hole 25 is connected to the oil drain nozzle 26.

[0039] The connecting block 17 has a round hole 27 corresponding to the oil leak nozzle 26. The oil leak nozzle 26 and the round hole 27 are fitted together in a sealing connection. The oil is collected through the annular groove 24 and enters the oil leak hole 25, and flows into the oil collection tank 5 through the oil leak nozzle 26 and the round hole 27.

[0040] like Figure 7The drying component 4 includes a block 28, which is a cuboid. A drying cavity 29 is provided on the block 28. The drying cavity 29 is a cylindrical cavity with openings at both ends. The drying cavity 29 is coaxially arranged with the transmission center line of the core wire. A number of air holes 30 are provided on the inner wall of the drying cavity 29. The air holes 30 are arranged in a circular array with the axis of the drying cavity 29 as the reference.

[0041] Block 28 has an air cavity 31, which is connected to the air hole 30. The air cavity 31 is connected to a fan through a pipe. The fan blows air from the air hole 30 through the air cavity 31 to dry the cored wire passing through the drying chamber 29.

[0042] In this embodiment, the diameter of the required oil-coated core wire is determined, and the scraper 20 with the corresponding diameter oil passage hole on the oil scraping assembly 3 is controlled to descend according to the diameter of the core wire, so that the axis of the oil passage hole is coaxial with the axis of the oil passage cavity.

[0043] Subsequently, the cored wire is manually pulled through the oil spraying assembly 2, the oil scraping assembly 3, and the drying assembly 4 in sequence, and the cored wire is laid on the guide wheels 9 at both ends of the workbench 1. Finally, it is fixed on the winding machine and provided by winding.

[0044] Based on the diameter of the cored wire, the height of the guide wheel 9 is adjusted by extending or retracting the output end of the hydraulic telescopic cylinder 7, so that the central axis of the cored wire coincides with the central axis of the wire passage cavity 18.

[0045] Subsequently, based on the diameter of the core wire, the distance between the fuel injector 14 and the center of the ring 12 is adjusted by extending and retracting the output end of the hydraulic telescopic cylinder 13. This distance is positively correlated with the diameter of the core wire; that is, the smaller the diameter of the core wire, the smaller the distance between the fuel injector 14 and the center of the ring 12.

[0046] Then, the cored wire is wound and pulled by a winding machine. When the cored wire passes through the oil spraying assembly 2, it is sprayed with oil from all directions by four nozzles.

[0047] After the oil spraying is completed, the cored wire passes through the wire hole 23 of the scraper 20. The excess oil on the cored wire is scraped off by the rubber ring on the side of the wire hole 23 that is close to the direction of the cored wire. The scraped oil enters the annular groove 24 and is collected in the oil drain hole 25 under the action of gravity. It then flows into the oil collection tank 5 through the oil drain nozzle 26 and the round hole 27. The oil in the oil collection tank 5 is filtered by the oil filter and then re-enters the oil tank through the pipeline for reuse.

[0048] After the oil is scraped off, the cored wire passes through the drying chamber 29. The fan blows air through the air chamber 31 and out of the air hole 30 to dry the oil on the cored wire. The dried cored wire is then wound onto the winding machine, thus completing the oiling process of the cored wire.
