Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cold-rolled steel pipe production, and particularly relates to a cold-rolled steel pipe oil removal device. BACKGROUND

[0002] In recent years, the cold-rolled steel pipe industry in China has developed rapidly. A large amount of lubricating oil is used in the production process of the cold-rolled steel pipe to reduce the temperature of the cold-rolled steel pipe. However, a large amount of lubricating oil adheres to the surface of the cold-rolled steel pipe, which causes great inconvenience in transportation. In addition, the oil stains can absorb dust during transportation, increasing the difficulty of processing the cold-rolled steel pipe later.

[0003] The commonly used surface oil removal method for the current cold-rolled steel pipe and the defects thereof are as follows:

[0004] The placement method is to make the steel pipe placement frame have a certain slope, and an oil receiving groove is arranged below the placement frame. The lubricating oil on the cold-rolled steel pipe directly drips into the oil receiving groove. However, this oil removal method cannot completely remove the lubricating oil on the surface of the steel pipe, and a large amount of lubricating oil remains on the surface of the steel pipe, causing waste.

[0005] The soaking method is to soak the cold-rolled steel pipe in the degreasing liquid for oil removal. However, the soaking method is limited by the terrain and cannot completely soak the long cold-rolled steel pipe in the degreasing liquid, which affects the oil removal effect. In addition, the removed lubricating oil cannot be reused.

[0006] An annular rubber sleeve is arranged in the oil removal sleeve. When the cold-rolled steel pipe passes through the oil removal sleeve, the annular rubber sleeve scrapes off the lubricating oil on the surface of the cold-rolled steel pipe and collects it. However, during the process of the cold-rolled steel pipe passing through the oil removal sleeve, due to the machining precision of the cold-rolled steel pipe and the machining precision of the oil removal sleeve, there is a gap between the annular rubber sleeve and the surface of the cold-rolled steel pipe, so that the lubricating oil on the surface of the cold-rolled steel pipe cannot be completely removed. SUMMARY

[0029] As Figure 3 shown, outer layer oil removal skin pad 41 is located in the top of the middle position of box 1 cover, and the two sides of outer layer oil removal skin pad 41 are connected with fixed block 11 set on box 1, the outer side of inner layer oil removal air bag 42 is provided with annular protrusion 421, one end of charging and exhausting controller 43 is set in inner layer oil removal air bag 42, the other end of charging and exhausting controller 43 is connected with PLC control 5, one end of vacuum controller 44 is set in inner layer oil removal air bag 42, the other end of vacuum controller 44 is connected with PLC controller 5.

[0030] Still include alarm device, alarm device is set in the side of outlet detection device 22, and is connected with PLC controller 5, when the detection value of outlet detection device 22 is higher than the residual amount set, triggers alarm device, and separately places its unqualified cold-rolled steel pipe, to facilitate oil removal treatment again.

[0031] Fixed block 11 is detachably connected with outer layer oil removal skin pad 41, by disassembling fixed block 11, the replacement of outer layer oil removal skin pad 41 and inner layer oil removal air bag 42 is realized, the bottom of box 1 is provided with roller 12, after oil removal process, it is convenient to move the equipment, and place in suitable position.

[0032] Working process:

[0033] The cold-rolled steel pipe oil removal device is not directly connected with the steel pipe machine for producing the cold-rolled steel pipe, and the produced cold-rolled steel pipe is horizontally moved by the conveying roller of the steel pipe machine, that is, the cold-rolled steel pipe enters the oil removal device at the end, and the cold-rolled steel pipe sequentially passes through the entrance detection device 21, the entrance guide device 31, the exit guide device 32 and the exit detection device 22, the entrance detection device 21 detects the initial value of the lubricating oil, and the cold-rolled steel pipe continues to move horizontally through the entrance guide device 31.

[0034] When the cold-rolled steel pipe just contacts the outer layer oil removal pad 41, the charging and discharging controller 43 is opened and the vacuum controller 44 is closed under the action of the PLC controller 5, so that the outer layer oil removal pad 41 and the inner layer oil removal air bag 42 are tightly attached to the cold-rolled steel pipe, the lubricating oil on the surface of the cold-rolled steel pipe flows into the box 1, is collected through the oil drain port 45 at the bottom of the box 1, and continues to move horizontally under the action of the exit guide device 32 until the end of the cold-rolled steel pipe passes through the exit detection device 22, and the collected objective data is displayed on the PLC controller 5. If the detected value at this time does not trigger an alarm signal, it means that the oil removal effect of the cold-rolled steel pipe is qualified, if the detected value at this time is higher than the set standard value, an alarm signal is triggered, which means that the oil removal effect of the cold-rolled steel pipe is unqualified, and the cold-rolled steel pipe should be taken out separately for re-oil removal treatment. Under the action of the PLC controller 5, the charging and discharging controller 43 is closed and the vacuum controller 44 is opened, vacuumizing treatment is carried out, and the cold-rolled steel pipe is reset for the next oil removal.

[0035] After the oil removal process is completed, the unqualified cold-rolled steel pipe is treated again by the cold-rolled steel pipe oil removal device until the set residual amount is reached, and after the work is completed, the cold-rolled steel pipe oil removal device can be placed in a suitable position without occupying space.
