Description
Technical field
The present invention relates to metal materials to roll processing technique field, more particularly to one kind uses cross-feed relative to milling train
Longitudinal rolling mode reduces the anisotropic Finish Machining System of metal material and method.
Background technique
It is a variety of that metal material milling method can be generally divided into axial rolling, oblique milling, transverse rolling etc..The direction of metal flow when axial rolling
It is identical as the roller surface direction of motion, for example, strip, round steel, bar, fashioned iron etc. it is normal rolling belong to axial rolling, axial rolling is also
Metal rolled principal mode.The direction of motion of the flow direction of metal perpendicular to deformable metal when transverse rolling, such as cross wedge rolling etc.,
Some tapered axis products can be rolled.Oblique milling is then between axial rolling and transverse rolling, the flow direction of deformable metal and roll
The direction of motion it is angled, metal is also rotated around this body axis other than forward travel, i.e. rolled piece is integrally spinned advance
Movement, such as rolling of steel pipe, steel ball, screw thread etc..
Flow of metal direction is constant when axial rolling, and metal is easy to produce anisotropy, and in addition product width is not easily controlled, and uses
It needs to change billet size when big blank rolling light section or controls rolled piece width with edger roll, edging pass.When transverse rolling and oblique milling
Rolled piece generates rotary motion, is not suitable for the product of rolling noncircular cross section.Axial rolling can obtain larger width using the method for induced spread
The rolled piece of degree, but rolling direction does not change, therefore cannot improve the anisotropy of material.In order to improve each to different of material
Property, it is general using the method for replacing reversible rolling in length and breadth, but this milling method is limited by roll width, cannot roll compared with
Long rolled piece.
Summary of the invention
The present invention provides a kind of anisotropic Finish Machining System of reduction metal material and methods, in two conventional rollings
Improving on the basis of machine can be produced, and rolled piece entrance that rolled piece is opened up from mill housing enters, then by roll along with
The vertical direction of charge length is back and forth rolled, and rolling interval, what control rolled piece was opened up on the mill housing of the other side rolls
Part export direction is moved and is shut out；The present invention can make rolled piece obtain big deformation in the direction of the width, rolled piece can also be made to exist

In the present embodiment, if 2 frame duo mills 14, every frame duo mill 14 rolls 2 passages, rolls 4 passages altogether.It rolls
Part 6 is the wire rod of diameter 8mm, and the minimum roll gap in small roll gap area is 1.5mm, and the maximum roll gap in big roll gap area is 23mm, after rolling
The width of rolled piece is 30mm.
The operation of rolling of the present embodiment is roughly the same with embodiment 1, the difference is that rolling by first duo mill 14
Rolled piece 6 afterwards enters back into the second frame duo mill 14 and is rolled, and the operation of rolling on 2 frame duo mills 14 is identical.
In the present embodiment, rolled piece mill speed is 2 times/second, and the amount of feeding after rolling is 50mm, mill length per second every time
For 100mm, rolls 6 meters within 1 minute, roll 360 meters per hour, hourly output 102kg.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
