Utility model content
The utility model object is to provide a kind of steel pipe cold rolling device, and object is the lubricating oil of base inside pipe wall to carry out secondary uniform distribution, is convenient to the roll forming of base inside pipe wall.
For above problem, provide following technical scheme: a kind of steel pipe cold rolling device, comprise the plug, core bar and the connecting bar that are placed in base pipe, plug and core bar are connected to the two ends of connecting bar; It is characterized in that: the diameter of described connecting bar be greater than corresponding plug and core bar and with base inside pipe wall matched in clearance, described connecting bar comprises pitman body and is socketed its outside oil-collecting cover, the surface of described oil-collecting cover arranges multiple axial oil storage grooves, the oil-collecting sheet of being close to base inside pipe wall is set between described core bar and connecting bar, the oil-collecting through hole that is communicated in oil storage grooves is set on described oil-collecting sheet.
The utility model is also further set to, and described oil-collecting sheet is umbrella setting and its opening direction is right against plug.
The utility model is also further set to, and the revolving bed being fixed by socket with the end of core bar is set on described oil-collecting sheet, and described oil-collecting through hole is in curved and multiple convolution settings centered by revolving bed in the radial direction of umbrella oil-collecting sheet.
The utility model is also further set to, and described oil storage grooves equidistantly arranges on the surface of oil-collecting cover.
The utility model is also further set to, and described oil-collecting sheet comprises umbrella matrix and the oil collecting ring corresponding with base inside pipe wall, and described oil collecting ring is connected with a side corresponding with plug on umbrella matrix.
The beneficial effects of the utility model, in the process that base pipe is rolled, base pipe can constantly move to roll direction, the oil that now can inwall latter half of base pipe be adhered to through oil-collecting sheet carries out scraping collection, along with the movement of base pipe, lubricating oil in oil-collecting sheet upper end can be in the oil-collecting through hole of arc flows to the oil removing groove that oil-collecting puts in defluent process, due to the multiple convolution settings on the oil-collecting sheet of umbrella of oil-collecting through hole, can make the lubricating oil through scraping farthest flow in oil removing groove, in the process of rolling, core bar drives connecting bar and plug to rotate, now the lubricating oil in oil removing groove is attached to base inside pipe wall again through centrifugal rotation, and it is more abundant that lubricating oil adheres to, oil-collecting sheet is after the oil-collecting of a period of time, oil removing groove and plug and base inside pipe wall have been full of lubricating oil, can fully realize carrying out oiling near near base inside pipe wall roll, can solve base inside pipe wall lubricating oil and be difficult to the problem of adding and continuing to adhere to.
