Abstract
The invention relates to rolling mills, in particular to an excessive-opening-prevention type copper pipe rolling mill. The excessive-opening-prevention type copper pipe rolling mill comprises a rolling mill body, a cover plate hinged to the rolling mill body and a hydraulic cylinder for driving the cover plate to be opened and closed, and is characterized by further comprising a limiting structure for limiting the opening degree of the cover plate. The limiting structure comprises a limiting switch and a control device. When the limiting switch detects that the cover plate is opened by 85 degrees, the control device stops the hydraulic cylinder, and the cover plate cannot continue to be opened. According to the excessive-opening-prevention type copper pipe rolling mill, excessive opening of the cover plate cannot be generated, and the problem that an existing rolling mill will generate the phenomenon that the opening angle is larger than 90 degrees, and consequently, the hydraulic cylinder cannot close the cover plate can be solved.
Description
Technical field
The present invention relates to milling train, particularly relate to a kind of anti-excessive open type copper pipe rolling.
Background technology
Need to use milling train in the manufacturing process of copper bar.Chinese Patent Application No. be 200820014774X, publication number is CN201239741Y, name is called in the patent document of " lift working roll mixes roller " and discloses a kind of existing milling train.Existing milling train comprises rolling mill body, be articulated with the cover plate on rolling mill body and drive the hydraulic cylinder of cover plate opening-closing.Existing milling train has the following disadvantages: the weight of milling train cover plate own is very heavy, the phenomenon that lid aperture is greater than 90 degree can be produced, the aperture of lid be greater than 90 ° then hydraulic cylinder cover plate can not be shut, at this moment need operating personnel to go process that lid just can be made for a long time to recover; Isolating affection is poor; Cover plate do not have handle, inconvenience during manual operation cover plate.
Summary of the invention
The invention provides a kind of cover plate and can not produce the anti-excessive open type copper pipe rolling that transition opens, solve existing milling train and can produce opening angle and be greater than the phenomenon of 90 ° and problem that cover plate can not be shut by the hydraulic cylinder that causes.
Above technical problem is solved by following technical proposal: a kind of anti-excessive open type copper pipe rolling, comprise rolling mill body, be articulated with cover plate on rolling mill body and drive the hydraulic cylinder of cover plate opening-closing, it is characterized in that, also comprise the position limiting structure of the aperture limiting described cover plate, described position limiting structure comprises limit switch and control device, described control device described limit switch detect described cover plate stop described hydraulic cylinder when being opened to 85 ° and make described cover plate can not continue open.Cover plate can be made to be merely able to unlatching 85 °, and namely the aperture of cover plate is 85 °, produces, thus can not produce the situation that cover plate can not close up by hydraulic cylinder so the open cap period of the day from 11 p.m. to 1 a.m can not produce the phenomenon that cover plate opens more than 90 °.
As preferably, described rolling mill body is provided with feet, described feet comprises the hypomere that epimere and upper end are set in epimere lower end, the shock-absorbing spring supporting described epimere is provided with in hypomere, the upper end of described epimere is provided with connecting ring, inner ring is equipped with in described connecting ring, described inner ring is linked together with described connecting ring by rubber ring, described rubber ring is provided with several blind holes distributed along rubber ring circumference, described blind hole is arranged at inner peripheral surface or the outer peripheral face of described rubber ring, division board is provided with in described blind hole, described blind hole is divided into radially-arranged two cavitys along rubber ring by described division board, described division board is provided with the main friction passage being communicated with described two cavitys, friction plate is provided with in described main friction passage, described friction plate is equipped with the friction lever that can radially slide along rubber ring, described friction lever is provided with a friction passage, the elastomeric cap arched upward towards blind hole inside is stamped in the openend of described blind hole, described inner ring is equipped with connecting pin, described epimere is linked together with described rolling mill body body by described connecting pin.The vibration isolating effect of milling train can be improved.The shock insulation process of the technical program is: by liquid filling in blind hole, when producing vibration, reciprocal radial displacement can be produced between inner ring and connecting ring, when this displacement can cause blind hole to be out of shape, blind hole distortion and drive that position liquid in the inner flows back and forth between inner chamber body and outer chamber, the rocking of friction plate and friction lever, liquid flow and friction plate and friction lever rock and change vibrational energy into heat energy in process and consume.If vibrate less and be not enough to impel blind hole to be out of shape time, now only have rocking of liquid, during liquid sloshing, friction lever produces and rocks and energy-absorbing, friction lever is set and can improves the absorption that frequency low-amplitude is vibrated, make the present invention not only can absorb the vibrational energy of isolation high amplitude, can also absorb the vibrational energy of short arc, therefore isolating affection is better.When this structure can make the blind hole of side be squeezed, the blind hole of opposite side then produces diastole instead of simultaneously pressurized or diastole, and making when the positive and negative amplitude vibrated is interval can both effectively absorbing, and absorbing efficiency is high.This structure is also because inner ring is connected by rubber ring with connecting ring, and connecting ring is not easy to produce distortion, and distortion fecund is born in inner ring, so only need after distortion to change inner ring.
