By the press roll device, billet rollover caused by unavailable hole patterns of the vertical rolls during vertical rolling can be prevented effectively, multi-specification rolling can be achieved on the premise that rolls of a single rolling machine need not to be replaced, time for roll replacing is saved, production efficiency is increased, and production cost is lowered.
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 is fixed in rolling-mill housing and can only left and right translation can not be elevated, also one section of effective operation face of roll can only be utilized in the operation of rolling, make roll can only open single pass, the pass of often kind of specification all can only the corresponding shape of rolling, and can only use once, if realize different rolled form on same rolling line, roll must be changed, cause the frequent replacing of roll, not only lose time, and replacing roll causes cost high frequently, the drawback that waste is many.How to increase work roll cooling number of times, extend working time, reduce and change roll number of times and time, even do not need to change roll, also do not need open cell type on roll, just become the problem wherein needing to solve.
CN102363158A discloses the vertical miller of roll shifting up and down " a kind of can ", and this milling train comprises the rolling mill body be made up of rolling-mill housing, vertical rolls system, pressure tester, also comprises the lowering or hoisting gear surrounded by base, four columns.This milling train is by the integral elevating of opposite roller milling train, and realizing roll can play up and down, can use the roll of the many scope of operations of porous type, decrease roller system replacing number of times and time, improve roll working life and rolling efficiency.But this milling train only overcomes conventional mill can only open single pass, need the frequent drawback changing roll, do not solve and realize different rolled form on same rolling line, and do not need roll change, also do not need the problem of open cell type on roll.
Summary of the invention
The object of the invention is to overcome prior art deficiency, provide a kind of and realize different rolled form on same rolling line, and do not need to change roll, also do not need the vertical miller of the band press-roller device of open cell type on roll.
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 base, the rolling mill body of edger roll and drive system composition, 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 is connected with the connecting rod being fixed on sill top through entablature, the bottom of sill is provided with gripper shoe, pressure roller is arranged between gripper shoe, guide cylinder is arranged between entablature and sill.
Described oil cylinder is four, is symmetricly set on the corner on entablature top by pressing plate, its range H=h-d, and in formula, h is the upper surface of entablature and the distance of rolling steel billet finished product upper surface, and d is the most minimal thickness of rolling steel billet finished product.
The dual-side of described entablature is fixedly connected with rolling-mill housing, and middle part is provided with through hole.
Described pressure roller is two, is arranged on the both sides on bottom rail beam length limit respectively 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, longitudinally has at least one through hole, the upper port of guide cylinder through the through hole of entablature, the outer wall of guide cylinder and the hole wall of through hole tangent, lower port is fixed on the upper surface in the middle part of sill.
The setting of press-roller device of the present invention, when rolling steel billet side, four oil cylinders control the pressure roller of two reversible rollings, the degree thickness different according to rolling steel billet rises and declines, all the time be pressed in the upper surface of rolling steel billet near edger roll both sides stably, prevent the rollover that steel billet causes because of the non-open cell type of edger roll.Guide cylinder, along with the lifting of pressure roller, slides up and down in the through hole of entablature, plays effect that is stable and fixed guide fittings, the rolled piece displacement force produced when simultaneously offsetting edge rolling.
Compared with prior art, advantage of the present invention is:
1, production efficiency is high.Due to the setting of press-roller device of the present invention, pressure roller is pressed in the upper surface of rolling steel billet near edger roll both sides all the time stably, effectively can prevent the rollover that steel billet causes because of the non-open cell type of edging roll in rolling on edge process, realizing single milling train is not needing under the prerequisite changing roll, realize multi items rolling, save roll changing time, improve production efficiency, reduce production cost.
2, investment cost is low.Due to the setting of press-roller device of the present invention, the edging roll of anapsid is equivalent to a pair omnipotent edging roll, substantially increase the utilization rate of often pair of edging roll, not only eliminate the operation of open cell type on the edging roll body of roll, and the deposit decreased edging roll, save spare part expense, also a saving the investment cost of the equipment such as the lowering or hoisting gear (before becoming roller) before and after rolling on edge simultaneously.
3, saving energy.Due to the setting of press-roller device of the present invention, eliminate the lowering or hoisting gear before and after milling train, shorten the length of production line, make production line more compact, decrease the heat loss of steel billet in the operation of rolling, reduce energy consumption.
