Abstract
Description
Technical Field
[0001] This utility model relates to the field of transposed wire production technology, and in particular to an automatic oiling device for transposed wire production. Background Technology
[0002] During the production of transposed conductors, friction occurs between the cores of the enameled wire, whether in the transposition stranding stage, the winding stage, or the transformer coil winding stage. Especially during transposition stranding, the conductors need to slide relative to each other under significant pressure. If the surface friction coefficient of the enameled wire is too high, it will not only increase the thrust of the sliding displacement, making it difficult for the conductor to deform properly, but also increase the rate of enamel film damage during the pushing deformation of the enameled wire, thus affecting product quality and performance.
[0003] In existing technologies, oiling of wires is mostly done manually. However, since the wear of each oiling block is different, it is difficult to ensure uniform oiling by manual oiling.
[0004] Based on the above-mentioned technical problems, this utility model proposes an automatic oiling device for the production of transposed conductors. Utility Model Content

Detailed Implementation
[0017] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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 utility model based on the specific circumstances.
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Example 1 like Figure 1 and Figure 2 As shown, an automatic oiling device for producing transposed wires includes a stranded wire reel 1, which is fixedly connected to a rotating shaft 11. The rotating shaft 11 drives the stranded wire reel to rotate. Guide blocks 5 and a gear ring 6 are rotatably installed on the surface of the stranded wire reel 1. The gear ring 6 is used to adjust the angle of the guide blocks 5. A gear 51 is fixedly installed on the guide blocks 5 corresponding to the position of the gear ring 6 and meshes with it. A fixed wheel is installed on the inner wall of the gear ring 6 to limit the angle of the gear ring 6. The guide blocks 5 are evenly distributed along the circumference of the stranded wire reel. The number of guide blocks 5 can be determined according to the actual use. A clamping plate 53 is installed above the guide hole at the front end of the guide block 5. The clamping plate 53 is fixed to the guide block 5 by bolts 52. An oiling block 54 is installed between the clamping plate 53 and the guide block 5. The oiling block 54 can be made of an oil-absorbing material such as sponge or felt. The wire passes through the guide hole between the two oiling blocks 54. When the wire passes through the oiling block 54, the oiling block 54 applies oil to the wire.
[0020] like Figure 1As shown, to solve the problem of replenishing lubricating oil during the production of transposed conductors, a lubrication device is installed on the stranded wire spool. An oil trough 2 is installed directly below the stranded wire spool, and the size of the oil trough 2 is completely larger than the projected area of the stranded wire spool and the guide block. A lubrication pipe 2 is installed above the oil trough 2, next to the stranded wire spool, either on the left or right side. The height of the oil outlet of the lubrication pipe is above the center height of the stranded wire spool, and the oil outlet trajectory of the oil pipe coincides with the rotation trajectory of the guide block 5, automatically lubricating the oiling block 54. An oil pump 3 is installed in the oil trough below the oil pipe 4. The oil outlet of the oil pump 3 is connected to the oil pipe 4, and the oil suction port of the oil pump 3 is connected to a filter screen to filter impurities. The lubricating oil is sucked in by the oil pump 3, flows out through the oil pipe 4, and drips onto the oiling block 54, where it is absorbed. Excess lubricating oil can drip into the oil trough 2 below, realizing the recycling of lubricating oil.
[0021] Example 2 like Figure 3-7 As shown, an automatic lubrication device for transposition wire production differs from Embodiment 1. Embodiment 1 can automatically lubricate the oiling block 54, but when lubricating the oiling block 54, excess lubricating oil will be sprayed onto the surface of the guide block 5 and rotated by the guide block 5. During the rotation, lubricating oil will inevitably drip down, landing on the surface of the rotating shaft 11 or being thrown out of the oil tank by centrifugal force and falling onto the ground, causing environmental pollution.
[0022] Below the oil outlet of oil pipe 4 is a mounting plate 7, which is connected to oil pipe 4 by bolts. An oil baffle 73 is rotatably mounted on the mounting bracket 76 of mounting plate 7. A lever 77 is mounted below the oil baffle. The installation position of the oil baffle 73 is as follows: Figure 4 As shown, the dashed line represents the oil outlet trajectory and the rotation trajectory of the guide block 5. The oil baffle 73 is installed at an angle above the point where the oil outlet trajectory and the rotation trajectory of the guide block 5 coincide. Before the guide block 5 rotates to the oil filling position, the lubricating oil will drip onto the oil baffle 73, enter the oil filter housing 71 below, and then be directly discharged into the oil trough 2 for return oil circulation. A telescopic rod 74 is connected to the right end of the oil baffle 73. The telescopic rod is a spring rod and is rotatably connected to the oil filter housing 71. The oil filter housing 71 is installed in the slide groove 75 of the mounting plate 7 via a slider, and a damping rod 9 is connected between the mounting plate 7 and the oil filter housing 71. The guide block 5 rotates... Before reaching the refueling position, contact the lever 77 to lift the oil baffle 73 upwards, moving it away from the lubricating oil outlet path. When the guide block 5 rotates to the refueling position, lubricating oil can be sprayed onto the oiling block 51. The oil baffle 73 is driven to rotate clockwise by the guide block 5. Under the action of the telescopic rod 74 and the slide groove 75, the oil filter shell 71 slides forward to catch excess lubricating oil. After the guide block 5 passes the oil baffle, it is driven to reset by the telescopic rod 74. Due to the action of the damping rod 9, the reset process is a slow reset. During the slow reset process, the oil filter shell 71 can collect the lubricating oil flowing down from the guide block 5.
[0023] like Figure 4 and Figure 5 As shown, an oil-absorbing block 72 is installed in the oil filter housing 71. The oil-absorbing block 72 can be made of industrial sponge or oil-absorbing cotton, etc. When the oil filter housing 71 moves forward, it can extend to the bottom of the guide block 5. The height of the oil-absorbing block 72 can contact the guide block 5, and absorb the lubricating oil adsorbed on the surface of the guide block 5. This prevents the guide block 5 from being thrown out of the oil tank 2 oil receiving range by centrifugal force during rotation, thereby avoiding pollution of the working environment.
[0024] like Figure 5 and 6 As shown, the bottom right end of the oil filter housing 71 has filter holes. During the resetting process of the oil return device, the oil baffle 73 can squeeze the oil suction block 72, squeezing out the lubricating oil adsorbed in the oil suction block to ensure the adsorption of the oil suction block. The upper surface of the mounting plate 7 has an oil storage tank, which is directly connected to the oil drain pipe 8. The lubricating oil received in the oil filter housing 71 can flow directly into the oil storage tank of the mounting plate 7 through the oil filter housing 71. The lubricating oil finally enters the lower oil tank 2 through the oil drain pipe 8 to circulate. The process of guiding excess lubricating oil directly into the oil tank 2 by the oil baffle 73 can prevent lubricating oil from falling onto the surface of the rotating shaft 11 or outside the oil tank 2 and contaminating the working environment.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
