Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] A lubricating device for cold drawing of steel bars, comprising a lubricant box 1, steel bar through holes 2 are provided on both the front and rear sides of the lubricant box 1, a fixing frame 3 is fixedly installed on the front side of the lubricant box 1 and outside the steel bar through holes 2, a driving guide wheel 4 and a driven guide wheel 5 are rotatably connected to the left side of the fixing frame 3, a collecting box 6 is fixedly installed on the back side of the lubricant box 1 and outside the steel bar through holes 2, and further comprising:

[0027] The filter assembly 7 is fixedly mounted on the top of the lubricant box 1 and is used for filtering the lubricant.

[0028] First, support feet 101 are fixedly installed at the four corners of the bottom of the lubricant box 1, and first liquid guide plates 102 are fixedly installed at the front and rear ends inside the lubricant box 1, and the two groups of first liquid guide plates 102 are symmetrically designed. The box cover on the top of the lubricant box 1 is opened to add lubricant, and the lubricant box 1 is raised by the support feet 101 to prevent the bottom from getting wet. When impurities in the lubricant are precipitated, they are accumulated in the middle through the two symmetrical groups of first liquid guide plates 102, which makes it convenient for the subsequent filter component 7 to extract the lubricant with impurities for filtering.

[0029] Furthermore, guide sleeves 301 are fixedly installed at both front and rear ends of the left side of the fixing frame 3, and a first motor 302 is fixedly installed on the right side of the fixing frame 3. The driving end of the first motor 302 is fixedly connected to the right end of the driving guide wheel 4, and a driving gear 303 is fixedly installed on the driving end of the first motor 302. A transmission gear 304 is fixedly connected to the right end of the driven guide wheel 5, and the transmission gear 304 is meshed with the driving gear 303. When the steel rod is inserted into the interior of the lubricant box 1, it is introduced between the driving guide wheel 4 and the driven guide wheel 5 through the guide sleeve 301, and the driving gear 303 is driven to rotate by the first motor 302. Under the transmission of the transmission gear 304, the steel rod is transported into the interior of the lubricant box 1 through the driving guide wheel 4 and the driven guide wheel 5.

[0030] The top end of the fixing frame 305 is threadedly connected with the adjusting screw 306, and the bottom end of the adjusting screw 306 is rotatably connected with the adjusting frame 305. The top end of the adjusting screw 306 is fixedly installed with a hand wheel 307. The outer sides of the driving guide wheel 4 and the driven guide wheel 5 are both provided with a cleaning cloth cover 308. When the steel rod is transported into the interior of the lubricant box 1 through the driving guide wheel 4 and the driven guide wheel 5, since the outer sides of the driving guide wheel 4 and the driven guide wheel 5 are both provided with a cleaning cloth cover 308, impurities on the surface of the steel rod can be cleaned to reduce impurities carried into the interior of the lubricant box 1 by the steel rod. When the cleaning cloth cover 308 needs to be cleaned later, the adjusting screw 306 is rotated upward by the hand wheel 307, so that the adjusting frame 305 moves up and the driven guide wheel 5 is lifted, thereby facilitating the removal of the cleaning cloth cover 308 on the outer sides of the driving guide wheel 4 and the driven guide wheel 5.

[0031] Furthermore, a discharge hole 601 is provided on the back of the collecting box 6, a recovery port 602 is provided at the bottom of the lubricant box 1, and a sealing cover is threadedly connected to the outer side of the recovery port 602. After the steel rod is attached with lubricant and enters the interior of the collecting box 6, the dripping lubricant can be discharged through the recovery port 602 and then recovered into the lubricant box 1, thereby avoiding the waste of lubricant, and then the steel rod is discharged from the discharge hole 601.

[0032] Secondly, the filter assembly 7 includes a filter box 701 fixedly installed on the top of the lubricant box 1, a second motor 702 is fixedly installed at the bottom end of the filter box 701, a filter basket 703 is fixedly installed above the second motor 702, and a pump 704 is fixedly installed on the top of the filter box 701. The input end of the pump 704 is connected to the bottom end of the lubricant box 1 through a pumping pipe 705, and the output end of the pump 704 is connected to the top of the filter box 701 through a delivery pipe 706. After the lubricant is used for a long time, some impurities carried by the rod will be attached therein. The pump 704 is started to extract the lubricant with impurities through the pumping pipe 705, and then it is delivered into the filter box 701 through the delivery pipe 706. The lubricant with impurities enters the filter box 701 and flows into the inner side of the filter basket 703. At the same time, the second motor 702 is started to drive the filter basket 703 to rotate, and the lubricant is filtered by centrifugal force, while the impurities remain on the inner side of the filter basket 703.

[0033] Finally, a second liquid guide plate 707 is fixedly installed at the bottom end of the filter box 701, a protective cover 708 is fixedly installed on the outside of the second motor 702, a connecting disk 709 is fixedly connected to the driving end of the second motor 702, and a connecting sleeve 710 is fixedly connected to the bottom of the filter basket 703 and located on the outside of the connecting disk 709. The connecting sleeve 710 is fixedly connected to the connecting disk 709 by a fixing bolt 711. The left side of the filter box 701 is rotatably connected to a box door 712. The filtered lubricant is re-introduced into the interior of the lubricant box 1 through the second liquid guide plate 707, thereby ensuring the quality of the lubricant. After the box door 712 is opened, the fixing bolts 711 are unscrewed to fix the connecting sleeve 710, so that the filter basket 703 can be taken out from the inside of the filter box 701 to clean the impurities inside, thereby ensuring the continuous use of the filter basket 703.

[0034] In this embodiment, the implementation scenario is specifically as follows: when the steel rod is inserted into the interior of the lubricant box 1, it is introduced between the driving guide wheel 4 and the driven guide wheel 5 through the guide sleeve 301, and the steel rod is transported into the interior of the lubricant box 1 through the driving guide wheel 4 and the driven guide wheel 5. Since the outer sides of the driving guide wheel 4 and the driven guide wheel 5 are both sleeved with a cleaning cloth sleeve 308, impurities on the surface of the steel rod can be cleaned, reducing the impurities carried by the steel rod into the lubricant box 1. After the steel rod is attached with lubricant and enters the interior of the collecting box 6, the dripping lubricant can be discharged through the recovery port 602 and then recovered into the lubricant box 1, thereby avoiding the waste of lubricant. Then the steel rod is discharged from the discharge hole 601. After long-term use, the lubricant will be accompanied by some impurities carried by the rod. The dynamic pump 704 draws away the lubricant with impurities through the pumping pipe 705, and then delivers it into the interior of the filter box 701 through the delivery pipe 706. The lubricant with impurities enters the filter box 701 and flows into the inner side of the filter basket 703. At the same time, the second motor 702 is started to drive the filter basket 703 to rotate, and the lubricant is filtered by centrifugal force, while the impurities remain on the inner side of the filter basket 703. The filtered lubricant is re-introduced into the interior of the lubricant box 1 through the second liquid guide plate 707. The entire operation process is simple and convenient. Compared with the existing lubrication device for cold drawing of steel bars, the utility model can clean the impurities on the surface of the steel bar through design, and can filter and recover the lubricant with impurities to ensure the quality of the lubricant.
