Abstract
The utility model relates to a cold mill for the metal forming field of the metallurgy profession, and namely a thin-belt cold mill with four rollers, composed of an electric pressing-down system, an upper working roller, a lower working roller, a left supporting roller, a right supporting roller, a top wheel, coiling machines, etc. A working machine seat has a dissymmetrical structure, and is arranged in a stirrup frame, comprising the large upper working roller and the small working roller, two supporting rollers and two top wheels. The two coiling machines are afforded with front and back tensions for rolling. The top wheel is controlled by a hydraulic cylinder, so the plate type can be adjusted. The utility model is used for rolling various harder and thinner thin-belt materials in uniform speed or in asynchronism. A clutch is also arranged on the universal-joint spindle of the smaller working roller, in order to implement the procedure of smoothing thin belts. The quality of smoothing the thin belts is improved by the clutch favorably. Compared with the prior art, the utility model has the characteristics of simple structure, low cost, easy operation and use, good rolling effect, etc. The utility model is specially used for rolling various harder and thinner thin-belt materials.
Description
Technical field
The utility model relates to metallurgy profession apparatus of metal molding field, specifically, is a kind of novel strip 4 cold mills.
Background technology
Along with development in Hi-Tech, high value added product demands such as its basic material such as accurate strip steel, alloy thin band, composition metal strip increase day by day, at present, produce these products 20 roller mills that use both at home and abroad more.This milling train be 40 ~ fifties by U.S.'s Sendzimir innovation and creation, its complex structure, processing and manufacturing precision requirement height, cost an arm and a leg, the converted products cost is too high, not too is fit to current product process requirements.Multiple rollers cold calender develops into 20 rollers according to being that cold rolling strap thickness and roller diameter exist the thin more roller of certain proportion relational theory rolled piece footpath more little from 4 rollers, for solve pony roll rigidity then backing roll quantity constantly add, variation has taken place from the asymmetrical rolling application in this situation.
Asymmetrical rolling essence is that to make rolling deformation district up-down rollers linear velocity produce a constant speed poor, therefore changes Plastic Deformation Force of Metals condition in the deformed area, generation direction pair of opposite shearing force between roll surface and rolled piece.Because the participation of shearing force significantly reduces draught pressure.This is highly beneficial to impelling rolled piece to extend, and also helps improving simultaneously template.Asynchronous rolling process can be made the most of the advantage than the thin steel band of hard alloy especially to production stainless steel and other.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of novel strip 4 cold mills, this milling train is structurally significantly simplified than external import 20 roller mills of current use, and easy operating uses, on rolling principle, adopt the asymmetrical rolling principle, use directly can shut out very thin strip equally than big roller, and roll thin steel alloy strip performance greater advantages to difficult, its design feature is: cold-rolling mill is made up of working stand, universal-joint spindle, double helical tooth wheel seat, reductor, main motor and coiling machine.Working stand adopts unsymmetric structure, is made up of up big and down small double-working and two backing rolls and two top wheels to be contained in the stirrup frame, and tension force was rolled before and after two coiling machines gave, and the top is taken turns and controlled adjustable complete plate by hydraulic cylinder.Simple, reliable, the easy row of template guiding mechanism.Wait speed rolling when up-down rollers footpath ratio equates with herringbone bear number of teeth ratio, exist a constant speed difference to produce a pair of shearing force in the deformed area and participate in distortion, this is to reducing draught pressure and extending favourable to strip.This is suitable for rolling hard and thin various thin-band materials.Clutch also is equipped with in universal-joint spindle end at less working roll, can carry out the smooth operation of single roller transmission when throw-out-of clutch.This is favourable to improving the strip product quality.
The utility model compared with prior art has simple in structurely, and cost is low, and easy operating uses, and effect of rolling is good, is specially adapted to rolling hard and thin characteristics such as various thin-band materials.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
By accompanying drawing as can be seen, the utility model by Electromechanical Screwdown System 1, top working roll 2, bottom working roll 3, about two backing rolls 4, top wheel 5, coiling machine 6 etc. form; Wherein Electromechanical Screwdown System 1 is arranged at the top of top working roll 2, and bottom working roll 3 is arranged at the bottom, the parallel respectively coiling machine 6 that is provided with in bottom working roll 3 both sides, two backing rolls 4 about the bottom of bottom working roll 3 is provided with, about two backing rolls 4 connect top wheel 5 respectively.
