Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a copper wire drawing and oiling device. Background Technology

[0002] Before drawing copper wire, drawing lubricant needs to be applied to make the wire pass through the die smoothly and also to cool it down. Currently, the most common method is to apply oil and then scrape off the excess oil. That is, the wire passes through an oil tank, and after applying oil, the excess drawing lubricant is removed by clamping the wire with a structure such as felt. This method first allows the wire to adhere to a lot of oil, and then scrapes off the excess oil. However, the drawing oil cannot be reused after being scraped off by the felt, resulting in waste. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention proposes an oiling device that can reduce the waste of lubricating oil during drawing operations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a copper wire drawing and oiling device, characterized in that it includes an oil tank, a lower roller rotatably connected to the oil tank, and an upper roller located above the lower roller. The oil tank has two parallel grooves on its two walls, each with a strip-shaped guide groove. A pressure roller is slidably connected within the two strip-shaped guide grooves. The pressure roller is made of permanent magnet material. The lower roller is partially located below the liquid surface in the oil tank. The lower roller includes an iron first axle and a cotton absorbent sleeve fixed outside the first axle. The pressure roller is parallel to the lower roller.

[0005] Furthermore, the upper roller includes a second wheel shaft and a rubber bushing sleeved outside the second wheel shaft. The upper part of the oil groove has two mounting ears, and the mounting ears have a vertically arranged waist-shaped groove. The second wheel shaft is inserted into the waist-shaped groove.

[0006] Furthermore, a tension spring is connected between each end of the first axle and each end of the pressure roller. The tension spring can further enhance the strength of the compression and drawing of the lubricating oil, and can be selectively applied.

[0007] Because the permanent magnet pressure roller can generate an attraction force with the iron first roller shaft, the attraction force can drive the cotton absorbent sleeve to be squeezed at the contact position of the pressure roller. This allows the cotton absorbent sleeve to squeeze out excess oil just before it comes into contact with the wire after absorbing the lubricating oil. The drawing lubricating oil adhering to the wire when it comes into contact with the cotton absorbent sleeve is controlled. Therefore, this method can reduce the waste of drawing lubricating oil compared to the existing method of first oiling and then scraping off the oil. Attached Figure Description

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 and Figure 2 As shown, the oiling device includes an oil tank 1, a lower roller rotatably connected to the oil tank 1, and an upper roller located above the lower roller. The two parallel walls of the oil tank 1 each have a strip-shaped guide groove 2. A pressure roller 3 is slidably connected in the two strip-shaped guide grooves 2. The pressure roller 3 is made of permanent magnet material. The lower roller is located below the liquid surface in the oil tank 1. The lower roller includes an iron first wheel shaft 4 and a cotton absorbent sleeve 5 fixed outside the first wheel shaft 4. The pressure roller 3 is parallel to the lower roller.

[0013] The upper roller includes a second roller shaft 6 and a rubber bushing 7 fitted over the second roller shaft 6. The upper part of the oil groove 1 has two mounting ears, each with a vertically arranged waist-shaped groove 8. The second roller shaft 6 is inserted into the waist-shaped groove 8. This allows the upper roller to press against the lower roller, ensuring that the thread presses firmly against the cotton absorbent sleeve and makes full contact with it.

[0014] Furthermore, a tension spring is connected between each end of the first wheel shaft 4 and each end of the pressure roller 3. The tension spring can further enhance the strength of the compression and drawing of the lubricating oil, and can be selectively applied.

[0015] Because the permanent magnet pressure roller 3 can generate an adsorption force with the iron first roller shaft 4, the adsorption force can drive the cotton absorbent sleeve 5 to be squeezed at the contact position of the pressure roller 3, so that when the cotton absorbent sleeve 5 is about to contact the wire after absorbing the lubricating oil, the excess oil can be squeezed out. The drawing lubricating oil adhering to the wire when it contacts the cotton absorbent sleeve 5 is controlled. Therefore, this method can reduce the waste of drawing lubricating oil compared with the existing method of first oiling and then scraping oil.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
