For CN201239741Y, entitled " lift working roll mixes roller " patent document in disclose a kind of existing milling train.It is existing
Some milling trains include rolling mill body, the cover plate being articulated with rolling mill body and the hydraulic cylinder for driving cover plate opening-closing.Existing milling train
Have the following disadvantages：Weight of milling train cover plate itself is very heavy, can produce the phenomenon that lid aperture is more than 90 degree, and the aperture of lid is big
In 90 ° then hydraulic cylinder cover plate can not be shut, at this moment need operating personnel to go processing to be lot more time to recover lid；Every
It is poor to shake effect；There is no handle on cover plate, inconvenience during manual operation cover plate.
The content of the invention
The invention provides the anti-excessively open type copper pipe rolling that a kind of cover plate will not produce transition unlatching, solve existing
Milling train can produce the problem of opening angle can not shut cover plate more than hydraulic cylinder caused by 90 ° of phenomenon.
Above technical problem is that solved by following technical proposal：One kind prevents excessive open type copper pipe rolling, including rolls
