Abstract
Description
Technical Field
[0001] This utility model relates to the field of coil drawing machines, specifically to a lubricating oil circulation device for coil drawing machines. Background Technology
[0002] Pipelines, as channels for various media, are widely used in many fields such as petroleum and natural gas, chemical and petrochemical, alternative fuels, nuclear power, thermal power and shipbuilding. Currently, coiled pipes, as a type of steel pipe product, have advantages such as long length and small footprint, and are widely used in various fields. Currently, coiled pipes are mainly produced by coil drawing machines (circular drawing machines). Coil drawing is a cold working of metal, and drawing oil must be used for lubrication during the process. Currently, the main problems in the production of coiled pipes by coil drawing machines are as follows: (1) When manually brushing the drawing oil onto the surface of the steel pipe with a brush, uneven brushing and missed brushing are likely to occur, affecting the processing quality of the coiled pipe; (2) When the drawing oil passes through the die along with the steel pipe, some of the drawing oil will be scraped out by the die. The scraped drawing oil drips down and easily causes dirt in the working environment, increasing the manpower expenditure for cleaning. Utility Model Content
[0003] The purpose of this utility model is to provide a lubricating oil circulation device for a pulverizing machine, which solves the technical problems of uneven oil brushing and dripping during pulverizing as pointed out in the background art.
[0004] To achieve the above objectives, this utility model provides a lubricating oil circulation device for a coiler, comprising a pump, a pumping pipeline, an oil return pipeline, an oil collection tank, an oil guide channel, and an oil lubrication tank. The pumping pipeline is disposed between the inlet of the pump and the oil collection tank. The oil return pipeline is disposed between the outlet of the pump and the oil lubrication tank. The oil guide channel is disposed between the oil collection tank and the oil lubrication tank. The oil in the lubrication tank flows into the oil collection tank via the oil guide channel. The oil in the collection tank returns to the lubrication tank via the pump, the pumping pipeline, and the oil return pipeline.
[0005] Furthermore, a guide plate is provided on the oil lubrication tank, and the inlet of the oil guide channel is located below the guide plate.
[0006] Compared with existing technologies, the advantages of this invention are that the raw material tube is lubricated by immersion before passing through the drawing die, eliminating the need for manual oiling, ensuring uniform lubrication and heat dissipation, and guaranteeing the quality of coil processing. The drawing oil circulates entirely within the main unit, eliminating the need for oil replenishment and reducing manpower. An overflow guide channel is added to the coil drawing equipment to collect and circulate the drawing oil, reducing oil loss and pollution to the working environment. Attached Figure Description

[0013] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0014] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.
[0015] 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.

[0016] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings.
[0017] See appendix for details Figures 1-2 As shown, the present invention discloses a lubricating oil circulation device for a coiler, comprising an oil pump 1, an oil extraction pipe 2, an oil return pipe 3, an oil collection tank 4, an oil guide channel 5, and an oil lubrication tank 8. The oil pump 1 can be a type of pump such as a tubular pump or a rod pump, and is fixed to the workbench for easy movement. The oil extraction pipe 2 and the oil return pipe 3 are connected by steel pipes and adapters; the oil extraction pipe 2 is connected to the inlet of the oil extraction pump 1, and the oil return pipe 3 is connected to the outlet of the oil extraction pump 1. The oil lubrication tank 8 is square, and the other end of the oil return pipe 3 is located inside the oil lubrication tank 8. The oil collection tank 4 is also square, and the other end of the oil extraction pipe 2 is located in the oil collection tank 4. An oil guide channel 5 is provided between the oil lubrication tank 8 and the oil collection tank 4; one end of the oil guide channel 5 is located below the overflow port of the oil lubrication tank 8, and the other end is connected to the oil collection tank 4. Preferably, a guide plate 7 is provided at the overflow port of the oil lubrication tank 8, and a guide hole is provided on the guide plate 7. The inlet of the oil guide tank 5 is located below the guide plate 7. The guide plate 7 is beneficial for guiding the steel pipe during the drawing process.
[0018] When using the drawing machine 10 for production, the end of the steel pipe 6 is passed through the oil lubrication tank 8 and then through the drawing die at the overflow port 9. Drawing oil is injected into the oil lubrication tank 8 until the steel pipe 6 is submerged, ensuring uniform and continuous lubrication and heat dissipation during the drawing process. The steel pipe 6 is pulled forward by the drum of the drawing machine 10, and some drawing oil leaks out through the overflow port. The leaked drawing oil flows through the oil guide channel 5 into the oil collection tank 4. The oil collected in the oil collection tank 4 is then pumped back into the oil lubrication tank 8 for use. The entire drawing process does not require manual oiling or replenishment; the oil is automatically collected and recycled. After a single drawing process is completed, the drawing die is removed, and the tail material is removed. The remaining drawing oil in the oil lubrication tank 8 flows from both ends into the oil guide channel 5 and is finally collected in the oil collection tank 4 for subsequent use.
[0019] In this invention, two sets of oil lubrication tanks 8 can be set up, which flow into the same oil collection tank 4 through the oil guide channel 5, enabling simultaneous operation of multiple workstations and improving efficiency.
[0020] The basic principles and advantages of this utility model have been described above. For those skilled in the art, the above embodiments are merely illustrative of the technical solutions of this utility model and not intended to limit it. Although this 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 or all of the technical features by reading this specification. Any obvious substitutions are within the protection scope of this utility model without departing from its concept.
