Abstract
The invention discloses a kind of transmission milling train separately, comprise roller case, gear-box and motor, between the corresponding gear-box of motor and motor and gear-box, be in transmission connection by transmission device, between corresponding roller case of gear-box and gear-box and roller case, connect by gear drive. The independent transmission milling train of the present invention, drives because every rolling mill all adopts an independent motor, and device structure is greatly simplified with respect to central driving, and simple and compact equipment structure is more conducive to improve the stationarity of equipment high-speed cruising; When collars when wearing and tearing of any rolling mill, can make up because the collars roller footpath of causing of wear and tear reduces by the mode of fine setting motor speed, thereby can improve the utilization rate of collars, the quantity of minimizing collars spare part; And between single passage, there is no the fixing ratio of depressing, make pass design more flexible; Simultaneously less, the standby redundancy of power of motor still less, can effectively reduce the cost of investment and production run.
Description
Technical field
The present invention relates to a kind of milling train, particularly a kind of high speed cantilever rolling mill.
Background technology
In modern wire production, conventionally adopt the mode that improves wire rod finish to gauge speed, higher to obtainOutput. The finish to gauge that high-speed rod is produced at present ensures that speed major part can reach 110m/s, even higher. For realityNow high mill speed like this, needs suitable high-speed rod-rolling mill, and the equipment generally using is at present wire rodFinishing mill, be met the product of dimensional requirement by the high-speed rolling of wire finishing mill, and ensure wire rodOutput. Past is because the dynamic velocity drop in high-speed rolling process cannot solve under so high mill speed,What therefore traditional wire finishing mill all adopted is central driving, drives 8 to 10 by a large motor simultaneouslyFrame wire finishing mill, realizes 45 ° of no twist rollings of topcross, is mechanically to divide by a gear-box and two major axisDo not drive multiple sets of teeth wheels, drive milling train and realize mechanical chain, thereby the problem of solution dynamic velocity drop is realExisting steady production.
Though can realize mechanical chain by central driving, but still have problems:
1) device structure relative complex, transmission chain length, the machine driving dependence between milling train is stronger, especiallyBe the gear-box of the first order, once certain part breaks down, can cause whole milling train to move.
2), owing to being central driving, in the time that the collars wearing and tearing of a certain rolling mill need to change, must change institute simultaneouslySome collars, to guarantee carrying out smoothly of rolling.
3) fixing gearratio between central driving and each rolling mill, makes pass design underaction.
Along with the progress of technology, Electrical Control Technology of today can meet dynamic velocity drop in high-speed rolling and ringThe problem of answering, therefore the wire rod fast mill of transmission possesses feasibility completely in control technology separately.
Summary of the invention
