[0002] The difference between the straight-in dry wire drawing machine and the water tank wet wire drawing machine in the final performance of steel wire products is that the steel wire drawn by the straight-in dry wire drawing machine has high strength and good consistency, while the steel wire drawn by the water tank wet wire drawing machine has less impurities and is bright on the surface.

[0003] When the steel wire is drawn in the straight-through wire drawing machine, it is drawn through an ordinary die box device with drawing lubricant powder. After drawing, a large amount of drawing lubricant powder adheres to the surface of the steel wire. Some steel wire products with special requirements need to obtain good mechanical properties after drawing in the straight-through wire drawing machine, and then be cleaned offline to achieve surface cleaning of the product, thereby obtaining better performance. In order to meet the special needs of the product, an offline separate cleaning process is added to the drawing process, and the production cost increases significantly.

[0004] like Figure 1 As shown, the original wire drawing die box device, the wire drawing die box 5 is welded by steel plates, the steel wire 13 passes through the cross guide wheel 12 and enters the powder chamber 20, the steel wire 13 adheres to the wire drawing powder in the powder chamber 20 through running vibration, and enters the die 2 through the wire drawing die sleeve 3, the wire drawing powder plays a lubricating role, the steel wire 13 is deformed in the die 2, and the wire drawing die 2 is locked by the locking member 1 to prevent loosening. The deformed steel wire 13 automatically takes out the wire drawing lubricating powder from the die 2, and a large amount of wire drawing powder adheres to the steel wire 13, affecting the cleanliness of the steel wire 13.

[0005] Related reference CN102728638A discloses a continuous lubrication device for alloy wire rod blank drawing die, in which the bottom of the lubricator container is connected to the die box of the rod blank drawing die through a connecting pipe, the die box is a hollow structure, and the die box and the grease container are filled with grease, a wire drawing die sleeve and a wire guide die sleeve are respectively arranged at both ends of the die box, and a wire drawing die is respectively arranged in the wire drawing die sleeve and the wire guide die. The alloy wire rod blank enters the die box from the wire guide die and then exits the die box from the wire drawing die. It cannot perform high-pressure washing on the garbage in front of the wire drawing die sleeve. Utility Model Content

[0030] A device for cleaning a high-speed wire drawing die box includes a cross-shaped guide pulley 12 and a die box 5 arranged in sequence along the wire drawing direction. The cross-shaped guide pulley 12 is installed in the liquid accumulation tray 14, and the liquid accumulation tray 14 is integrally installed on the die box 5. Inside the die box 5, a return plate 10, an overflow plate 7 and a die sleeve 3 are arranged in sequence along the wire drawing direction. The guide alloy 8 is welded and installed on the overflow plate 7. The material of the guide alloy 8 is YG8. The die sleeve 3 is welded on the mounting plate 21, and the mounting plate 21 is fixed inside the die box 5. A die 2 is arranged on the die sleeve 3, and a locking piece 1 is arranged on the die 2. The locking piece 1 is a locking screw. The locking piece 1 is fixed on the side wall of the die box 5 away from the cross-shaped guide pulley 12. The die 2 is fixed on the side wall of the die box 5 through the locking screw to prevent the wire drawing drum from vibrating and generating bamboo joint wires. A return cavity 11 is formed between the return plate 10 and the opposite wall of the die box 5, an overflow cavity 9 is formed between the overflow plate 7 and the return plate 10, and a liquid lubrication cavity 6 is formed between the mounting plate 21 and the overflow plate 7. In this application, the liquid lubrication cavity 6 is separately arranged at the die sleeve 3. In the liquid lubrication cavity 6, wire drawing powder can be added to lubricate and draw the steel wire 13, and lubricating oil can also be used to lubricate and draw the steel wire 13 and clean it, realizing two different lubrication methods of wire drawing powder lubrication and liquid lubrication, meeting the needs of different uses. When using liquid lubrication, the surface is clean and there is no residue, which meets the high-speed wire drawing of steel wires with special requirements, reduces the equipment and labor for secondary cleaning, and reduces the production cost.

[0031] A flushing cavity 19 is opened in the die sleeve 3, and the liquid supply pipe 18 is communicated with the flushing cavity 19. The fluid lubricant enters the die sleeve 3 with a 45° angle from the liquid supply pipe 18, high-pressure flushes the garbage accumulated in front of the die 2, and a large amount of fluid enters the inlet of the die 2 to increase the lubrication pressure.

[0032] The flushing cavity 19 is conical, the small end is communicated with the die 2, and the large end is facing the overflow plate 7. The conical flushing cavity 19 is convenient for the fluid lubricant to lubricate the steel wire 13. While avoiding the waste of lubricant, the flow form of the fluid lubricant is improved, the generation of fluid vortices is avoided, and the problem of erosion of the die sleeve 3 by the vortex action is avoided, improving the service life of the die sleeve 3.

[0033] A liquid supply pipe 18 is arranged on the die sleeve 3. The liquid supply pipe 18 forms an angle of 45° with the horizontal line, and the outlet of the liquid supply pipe 18 is aligned with the small end. The outlet of the liquid supply pipe 18 is aligned with the clearance between the steel wire 13 and the small end of the flushing cavity 19 of the die sleeve 3. The fluid lubricant wraps and lubricates the steel wire 13, which is suitable for high-speed wire drawing and is beneficial to improving the product quality of the steel wire 13.

[0034] Openings are made at the bottom of the reflux cavity 11 and the bottom of the liquid accumulation tray 14. These two holes are connected in parallel and then connected to the liquid return pipe 15. In this application, when the liquid level of the liquid lubricant in the overflow cavity 9 exceeds the reflux plate 10, it enters the reflux cavity 11 and is drained through the liquid return pipe 15 at the bottom to prevent the lubricant from overflowing.

[0035] Openings are made at the bottom of the liquid lubrication cavity 6 and the bottom of the overflow cavity 9. These two holes are connected in parallel and then connected to the drain pipe 16. A drain valve 17 is arranged on the drain pipe 16. When replacing the die, stop the supply of the liquid lubricant, open the drain valve 17 on the drain pipe 16 to drain the liquid lubricant in the two cavities completely, so as to avoid harm to the operators caused by the liquid lubricant.

[0036] Wire holes on the same horizontal line as the drawing hole of the die 2 are opened on the side wall of the die box 5 close to the cross guide pulley 12, the reflux plate 10, and the overflow plate 7. The steel wire 13 passes through the cross guide pulley 12, the reflux plate 10, and the overflow plate 7 in sequence and reaches the die 2. The wire drawing of the steel wire 13 is fast and smooth, and at the same time, the die wear is also low.

[0037] In this application, when wire drawing the steel wire, first pass the steel wire 13 through the cross guide pulley 12 and the reflux cavity 11, enter the guiding alloy 8 through the overflow cavity 9, then enter the liquid lubrication cavity 6 and then enter the die sleeve 3 and the die 2, and lock the die 2 with the locking screw. The fluid lubricant enters the die sleeve 3 through the liquid supply pipe 18 with a 45° angle, high-pressure flushes the garbage accumulated in front of the die 2, and a large amount of fluid enters the inlet of the die 2 to increase the lubrication pressure. The liquid level of the liquid lubricant in the liquid lubrication cavity 6 continuously rises, submerges the steel wire 13, and attaches the liquid lubricant to the surface of the steel wire 13. When the liquid level in the liquid lubrication cavity 6 exceeds the overflow plate 7, it enters the overflow cavity 9, which can attach the liquid lubricant to the surface of the steel wire 13 and is beneficial to the wire drawing of the steel wire 13. When the liquid level in the overflow cavity 9 exceeds the reflux plate 10, it enters the reflux cavity 11 and is drained through the liquid return pipe 15 at the bottom. When replacing the die 2, stop the supply of the liquid lubricant, open the drain valve 17 installed on the drain pipe 16 at the lower part of the liquid lubrication cavity 6 and the overflow cavity 9 to drain the liquid lubricant in the two cavities completely. A small amount of liquid will drip on the bottom plate of the die box 5 and be drained through the liquid return pipe 15 of the liquid accumulation tray 14.

[0038] The device has a compact and reasonable structure, adopts a simple mechanical structure, and meets different requirements. Two lubrication methods can be used. One is to use wire drawing lubricating powder, and the other can use liquid lubricant. This structure meets the requirements of traditional wire drawing and can also meet the on-line drawing of clean wires with special requirements, reducing production costs and improving production efficiency.
