Description
Technical field
The present invention relates to a kind of vertical miller, be specifically related to a kind of vertical miller with press-roller device.
Background technology
In traditional vertical miller, roll be fixed in the rolling-mill housing can only left and right sides translation can not lifting, also can only utilize one section effective operation face of roll in the operation of rolling, so that roll can only leave single pass, the pass of every kind of specification all can only rolling corresponding shape, and can only use once, if realize different rolled form at same rolling line, must change roll, cause the frequent of roll, not only lose time, and change frequently roll and cause cost high, the drawback that waste is many.How to increase the roll access times, extend working time, reduce to change roll number of times and time, even do not need to change roll, need to be on roll yet open cell type, wherein need the problem that solves with regard to having become.
CN102363158A discloses " a kind of up and down vertical miller of roll shifting ", and this milling train comprises the rolling mill body that is comprised of rolling-mill housing, vertical rolls system, pressure tester, also comprises by base, four lowering or hoisting gears that column surrounds.This milling train is realized up and down play of roll by the integral elevating of opposite roller milling train, can use the roll of the many scope of operations of porous type, has reduced roller system and has changed number of times and time, has improved roll working life and rolling efficiency.Can only open single pass but this milling train has only overcome conventional mill, need the drawback of frequent roll, not solve at same rolling line and realize different rolled form, and do not need roll change, need to be on roll yet the problem of open cell type.
Summary of the invention
The objective of the invention is to overcome the prior art deficiency, provide a kind of and realize different rolled form at same rolling line, and do not need to change roll, need to be on roll yet the vertical miller with press-roller device of open cell type.
The object of the present invention is achieved like this: a kind of vertical miller with press-roller device, comprise by base, be arranged on the rolling-mill housing on the base, the rolling mill body that edger roll and drive system form, it is characterized in that: also comprise a press-roller device, described press-roller device comprises oil cylinder, entablature, sill, pressure roller and guide cylinder, described oil cylinder is arranged on the top of entablature, the piston rod of oil cylinder passes entablature and is connected with the connecting rod that is fixed on sill top, the bottom of sill is provided with gripper shoe, pressure roller is arranged between the gripper shoe, and guide cylinder is arranged between entablature and the sill.
Described oil cylinder is four, is symmetricly set on four jiaos of entablature top by pressing plate, its range H=h-d, and h is the distance of upper surface and the rolling steel billet finished product upper surface of entablature in the formula, d is the minimal thickness of rolling steel billet finished product.
The dual-side of described entablature is fixedly connected with rolling-mill housing, and the middle part is provided with through hole.
Described pressure roller is two, is arranged on respectively the both sides on bottom rail beam length limit by gripper shoe.
Described pressure roller comprises roller, roll shaft, bearing and transparent cover, and roller is socketed in the outer rim of roll shaft, and bearing and transparent cover are socketed on the axle journal at roll shaft two ends successively, and is bolted on the two ends of roller.
The hardness of described roller is HRC40～50.
Described guide cylinder is cuboid, vertically has at least one through hole, and the upper port of guide cylinder is passed the through hole of entablature, and the outer wall of guide cylinder and the hole wall of through hole are tangent, and lower port is fixed on the upper surface at sill middle part.
The setting of press-roller device of the present invention, when rolling steel billet side, the pressure roller of two reversible rollings of four oil cylinder control, rise and descend according to the different degree thickness of rolling steel billet, all the time be pressed in stably rolling steel billet near the upper surface of edger roll both sides, prevent that steel billet is because of the not rollover that causes of open cell type of edger roll.Guide cylinder slides up and down in the through hole of entablature along with the lifting of pressure roller, plays the effect of stable and fixed guide fittings, the rolled piece displacement force that produces when offsetting edge rolling simultaneously.
Compared with prior art, advantage of the present invention is:
1, production efficiency is high.Because the setting of press-roller device of the present invention, pressure roller is pressed in rolling steel billet all the time stably near the upper surface of edger roll both sides, can effectively prevent steel billet in the rolling on edge process because of the not rollover that causes of open cell type of edging roll, realize that single milling train is not needing to change under the prerequisite of roll, realize that many kinds are rolling, save roll changing time, improved production efficiency, reduced production cost.
2, investment cost is low.Because the setting of press-roller device of the present invention, the edging roll of anapsid is equivalent to a pair of omnipotent edging roll, greatly improved the utilization rate of every pair of edging roll, not only saved the operation of open cell type on the edging roll body of roll, and reduced deposit to edging roll, save the spare part expense, also saved simultaneously the investment cost of the equipment such as lowering or hoisting gear (before becoming roller) of rolling on edge front and back.
3, saving energy.Because the lowering or hoisting gear of milling train front and back has been saved in the setting of press-roller device of the present invention, has shortened the length of production line, makes production line more compact, has reduced the heat loss of steel billet in the operation of rolling, has reduced energy consumption.
