Description

Technical Field

[0001] This utility model relates to the field of enameled wire lubrication technology, and in particular to a lubrication device for drawing ultra-fine enameled wire. Background Technology

[0002] Enameled wire refers to a conductor in which an insulating layer is formed by uniformly coating the surface of a bare wire with insulating varnish and then drying it. It is a key winding material for equipment such as motors and transformers and has a wide range of applications in the electronics and electrical fields. In the production process of ultra-fine enameled wire, the lubrication quality of the wire drawing process plays a decisive role in the quality and production efficiency of the enameled wire.

[0003] Existing lubrication systems lack precise adjustment mechanisms, making it impossible to flexibly adjust the immersion depth and wetting time of enameled wires in the lubricating fluid according to the characteristics of different specifications. Insufficient immersion depth and wetting time lead to inadequate lubrication, affecting the surface quality and physical properties of the enameled wire. Conversely, excessive immersion depth and wetting time not only waste lubricating fluid but may also cause other quality problems, failing to meet diverse production needs and making it difficult to maintain a constant fluid level. During production, the fluid level fluctuates due to lubricant consumption or equipment vibration. This instability results in inconsistent contact conditions between different parts of the enameled wire and the lubricating fluid, causing uneven lubrication and leading to quality differences on the surface of the enameled wire, such as localized scratches and uneven thickness, severely impacting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a lubrication device for drawing ultra-fine enameled wire, which solves the problem of poor lubrication effect caused by the inability to control the lubrication time and depth when lubricating enameled wire in the prior art.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the 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.

[0031] Reference Figure 1-5 A lubrication device for drawing ultra-fine enameled wire, comprising a lubrication box 1, and further comprising:

[0032] The first guide component 5 is disposed inside the lubrication tank 1 and is used to guide the enameled wire in the lubrication tank 1 and control the immersion depth of the enameled wire in the lubricating fluid.

[0033] Adjustment mechanism 4 is located inside the lubrication tank 1 to keep the liquid level in the lubrication tank 1 at the same height at all times;

[0034] Two sets of second guide components 7 are respectively set at both ends of the opening of the lubrication box 1, and cooperate with the first guide component 5 to make the enameled wire move smoothly.

[0035] During the drawing process, the enameled wire enters from one end of the lubrication tank 1 through the opening and is guided into the lubrication tank 1 by the second guide assembly 7. The first guide assembly 5 further guides the enameled wire to move in the lubricating fluid along a specific path, while controlling its immersion depth to ensure full contact between the enameled wire and the lubricating fluid. The adjustment mechanism 4 ensures that the fluid level in the lubrication tank 1 remains constant. Finally, the enameled wire smoothly exits the lubrication tank 1 via the second guide assembly 7 at the other end. This ensures that the enameled wire receives good lubrication during the drawing process, avoiding drawing quality problems caused by insufficient lubrication, and improving the production quality and efficiency of enameled wire.

[0036] Furthermore, the first guide assembly 5 includes an electric telescopic rod 51, which is fixedly mounted on the top of the lubrication box 1 by bolts. The output end of the electric telescopic rod 51 is fixedly connected to the mounting frame 52 by welding. The mounting frame 52 has an "n" shaped structure. Multiple first guide wheels 53 are rotatably connected between the two arms of the mounting frame 52 by bearings. The surface of the first guide wheels 53 is made of rubber to increase the friction between them and the enameled wire. The electric telescopic rod 51 is model ANT-26 with a stroke of 200mm, which meets the adjustment range of the immersion depth of the enameled wire.

[0037] By controlling the extension and retraction of the electric telescopic rod 51, the height of the first guide wheel 53 can be adjusted, thereby controlling the immersion depth of the enameled wire in the lubricating fluid. This allows for flexible adjustment of the immersion depth, ensuring the wire fully contacts the lubricating fluid and guaranteeing effective lubrication. Simultaneously, the rubber surface of the first guide wheel 53 increases friction, preventing the wire from slipping during guidance and making its movement more stable.

[0038] Furthermore, a slide rail 6 is fixedly installed on the inner wall of the lubrication box 1 by welding, and the mounting bracket 52 and the slide rail 6 are slidably connected.

[0039] Furthermore, the second guide assembly 7 includes a bracket 71 and a second guide wheel 72. The bracket 71 is fixedly connected to the lubrication box 1, and the second guide wheel 72 is rotatably connected to the bracket 71. The second guide wheel 72 and the first guide wheel 53 correspond one-to-one and their axis lines are in the same plane.

[0040] When the enameled wire enters and leaves the lubrication box 1, it is guided by the second guide wheels 72 at both ends, which cooperate with the first guide assembly 5 to ensure that the enameled wire can pass smoothly through the lubrication box 1, ensuring that the movement path of the enameled wire is smooth throughout the lubrication process and reducing wear and jamming of the enameled wire.

[0041] Furthermore, the adjustment mechanism 4 includes a motor 41 and a support plate 43. A connecting frame 3 is fixedly installed at the bottom of the lubrication box 1. The motor 41 and the connecting frame 3 are fixedly connected. A sleeve 42 is fixedly installed at the output shaft port of the motor 41. The sleeve 42 rotates through the bottom of the lubrication box 1. A sealed bearing is provided at the penetration point to prevent lubricant leakage. A screw 45 is fixedly installed at the bottom of the support plate 43. The screw 45 and the sleeve 42 are threadedly connected. A sealing gasket 44 is fixedly installed on the top of the support plate 43 with glue. The sealing gasket 44 is made of oil-resistant rubber. The motor 41 is model Y90S-4 with a power of 1.1kW. It is fixed to the connecting frame 3 at the bottom of the lubrication box 1. The power is adapted to the lifting load of the support plate. The forward and reverse rotation realizes the height adjustment of the support plate. The sealing gasket 44 is made of nitrile rubber with a thickness of 3mm to ensure the sealing effect.

[0042] When motor 41 rotates, it drives sleeve 42 to rotate, and screw 45 moves up and down under the action of the thread of sleeve 42, thereby moving pallet 43 up and down. The sealing gasket 44 on the top of pallet 43 is made of oil-resistant rubber to prevent lubricant leakage. The surfaces of pallet 43 and sealing gasket 44 have notches that fit the slide rail 6, allowing pallet 43 to slide along the slide rail 6. When the lubricant level changes due to use or other reasons, motor 41 controls the up and down movement of pallet 43 to adjust the actual lubricant capacity, thereby maintaining a constant liquid level. This effectively responds to changes in lubricant level, ensuring that the enameled wire is always in a suitable liquid level environment during lubrication, and ensuring the stability of the lubrication effect.

[0043] Furthermore, both the tray 43 and the sealing gasket 44 have notches on their surfaces that are adapted to the size of the slide rail 6, and the tray 43 and the slide rail 6 are slidably connected.

[0044] Furthermore, the outer wall of the lubrication tank 1 is provided with a liquid level observation window. The liquid level observation window is made of transparent oil-resistant glass and is marked with a standard liquid level scale. The operator can directly see the liquid level of the lubricating fluid in the lubrication tank 1 through the observation window and compare it with the standard liquid level scale. This allows the operator to monitor the liquid level of the lubricating fluid in real time, detect abnormalities in the liquid level in a timely manner, and take corresponding measures, such as adding lubricating fluid or adjusting the adjustment mechanism 4, to ensure the normal operation of the device.

[0045] Furthermore, the grooves of the first guide wheel 53 and the second guide wheel 72 are both V-shaped structures with an angle of 60°-90°, so that the enameled wire will not easily come off.

[0046] Furthermore, a controller 2 is fixedly installed on the surface of the lubrication box 1. The electric telescopic rod 51 and the motor 41 are both electrically connected to the controller 2. The controller 2 is a Siemens S7-200SMART model, equipped with an advanced microprocessor and an integrated control interface. It is electrically connected to the electric telescopic rod 51 and the motor 41 through RVV2×1.5 wires to achieve precise parameter control.

[0047] A liquid level sensor is installed on the inner wall of the lubrication tank 1. An ultrasonic liquid level sensor can be used. The sensor calculates the liquid level by emitting and receiving reflected signals, then converts the liquid level data into an electrical signal output. The sensor transmits the real-time monitored liquid level data to the controller 2. The controller 2 compares the received liquid level data with a preset standard liquid level. If the actual liquid level is lower than the standard level, the controller 2 sends a command to the motor 41, causing it to rotate forward, rotating the sleeve 42. The screw 45 moves upward under the action of the thread on the sleeve 42, and the support plate 43 rises accordingly, reducing the lubricant's capacity and thus raising the liquid level. If the actual liquid level is higher than the standard level, the controller 2 controls the motor 41 to rotate in the opposite direction, lowering the support plate 43 and increasing the lubricant's capacity, thus lowering the liquid level. In this way, real-time adjustment of the liquid level is achieved, ensuring that the liquid level is always maintained at the standard height.

[0048] In summary, add an appropriate amount of lubricating fluid to lubrication tank 1 through the liquid level observation window until the liquid level reaches the standard liquid level mark.

[0049] The ultra-fine enameled wire is introduced from one end of the lubrication box 1, passes around the second guide wheel 72 and the first guide wheel 53 in sequence, and exits from the second guide wheel 72 at the other end, ensuring that the enameled wire is located at the center of the V-shaped groove of the guide wheel.

[0050] Start the wire drawing equipment. The enameled wire moves under traction, and the second guide wheel 72 guides the enameled wire into the lubrication tank 1. The first guide wheel 53 guides the enameled wire to move along a predetermined path in the lubricating fluid and controls its immersion depth. The liquid level sensor monitors the liquid level in real time and transmits the data to the controller 2. The controller 2 controls the motor 41 to operate according to the liquid level and adjusts the liquid level height.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
