Description
Technical field
The present invention relates to metal materials to roll processing technique field, in particular to a kind of using the longitudinal rolling side of cross-feed
Formula reduces the anisotropic precise machining device of metal material and its method.
Background technique
Metal material rolling can be generally divided into the types such as axial rolling, oblique milling, transverse rolling.When axial rolling the direction of metal flow with roll
The roller surface direction of motion is identical, such as the rolling of strip, round steel, bar, fashioned iron etc. belongs to axial rolling, is the main shape of rolling
Formula.The direction of motion of the flow direction of metal perpendicular to warp tool when transverse rolling, such as cross wedge rolling etc. can roll some Varied sections
Axis products；Oblique milling is then between axial rolling and transverse rolling, and the flow direction of deformable metal and the direction of motion of roll are at certain
Angle, metal are also rotated around this body axis other than forward travel, and rolled piece is integrally spinned forward travel, such as steel pipe, steel
Ball, screw thread rolling 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 or 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 object of the present invention is to provide a kind of anisotropic precise machining device of reduction metal material and its method, overcome existing
There is the deficiency of technology, using two rollers or multi-roll mill milling train, so that rolled piece is entered rack from a side of memorial archway window, then exist
It is back and forth rolled on the direction vertical with charge length, during the gap of rolling, makes memorial archway window of the rolled piece to the other side
Mouth direction moves and shuts out, it is intended to so that rolled piece is obtained big deformation in the direction of the width, can also make rolled piece in the longitudinal direction
The periodic deformation needed is generated, material anisotropy is reduced, keeps material all directions mechanical property uniform.
To achieve the above object, the invention is realized by the following technical scheme:
One of technical solution of the present invention: a kind of anisotropic precise machining device of reduction metal material, is duo mill, including

100mm, roll circumference are divided into 4 planar section 51 and 4 arc sections 5, wherein plane segment length 108mm, circular arc segment length
125mm is divided into two parts, every part width 50mm on roll surface width, and rolling is made of two rolling mills, each mill milling
2 passages roll 4 passages altogether.Rolled piece 6 is the wire rod of diameter 8mm, and the roll gap that roll arc section is formed is 1.5mm, planar section
The maximum roll gap 23mm of formation, the wide 30mm of rolled piece after rolling.
The operation of rolling is that rolled piece 6 is passed through from rolled piece lengthwise position controller 3, enters milling train from 7 side of memorial archway, from
Memorial archway other side arrives rolled piece traverse feed controller 1 through rolled piece lengthwise position controller 3.When top working roll 5 and bottom working roll 8
Roll gap when being made of arc section 5, rolled piece lengthwise position controller 3 pushes rolled piece 6 to be rolled into roll gap.
After the completion of rolled piece process, rolled piece goes out roller central line, and roll continues to rotate at this time, when top working roll 5 and lower work
When the roll gap of roller 8 is made of planar section 51, rolled piece lengthwise position controller 3 pulls rolled piece 6 to be moved to initial position from position 65
66, meanwhile, rolled piece traverse feed controller 1 pulls rolled piece along roll transverse direction advance 50mm, waits and enters opening for next rolling process
Begin.Rolled piece constantly rolls, advances, until rolled piece all length is all completed to roll.In this example, rolled 2 times of rolled piece/
Second, advance 50mm every time, rolling 100mm per second, then rolls 6 meters within 1 minute, roll 360 meters per hour, hourly output 102kg.
When seeing Figure 10-1 to roll wider blank, roll is equipped with 6 planar sections, and local rolling can be carried out to blank；
Figure 10-2 is that only there are two planar sections for transmission top working roll band, and wherein lower roll can be complete cylindrical body；The roll of Figure 10-3
On set there are three planar section.Between adjacent plane section of the present invention separately by cylindrical surface, top working roll 5 and bottom working roll 8 match
Regular big roll gap area and small roll gap area can be formed along roll surface circumference afterwards.
See Figure 11 to Figure 12, when top working roll 5 and bottom working roll 8 of the present invention are cylindrical roll, can also be equipped on roll surface circumference
One or more steps or type groove can also be axially formed rule along roll surface after top working roll 5 and bottom working roll 8 match in this way
The big roll gap area and small roll gap area of rule bite the effect of rolled piece and the commutation of rolled piece direction.
See Figure 13, is the transmission and rolled piece arrangement schematic diagram of long universal-joint spindle of the invention, such drive apparatus will be inclined
From roll line, the space interference between rolled piece and equipment is avoided the occurrence of, keeps the operation of rolling of rolled piece unaffected.
The method for changing direction of motor rotation can be used when rolling wider rolled piece by the present invention, use two complete circles
Roller, the window of memorial archway is greater than 2 times of rolled piece width at this time.It, can also be in existing milling train base when needing more multi- pass rolling
On plinth, multiple duo mills are connected into open-train mill unit.The method of the present invention is also applied for duo mill, 4 roller mills or more
Roller mill.
Above embodiments are only purpose, the technical scheme and beneficial effects for the present invention will be described in detail and the specific reality chosen
Example, but should in no way limit protection scope of the present invention, it is all without violating the spirit and principles of the present invention, made kind

1) after rolled piece enters rack from the side of memorial archway, rolled piece is controlled using rolled piece lengthwise position controller, makes rolled piece in roller
Seam is moved forward and backward, and when rolled piece enters the big roll gap area of roll, rolled piece is pulled back to initial position, when rolled piece enters the small of roll
Rolling is realized when roll gap area；
2) using the lateral displacement of rolled piece traverse feed controller control rolled piece, return to rolled piece in situ and axial to another along roll
The movement of side mill housing window direction, makes rolled piece enter next rolling cycle；
3) step 1) and step 2 are repeated, so that rolled piece is formed extension or periodically abnormity deformation in the longitudinal direction, until complete
At the rolling of entire rolled piece.
8. a kind of anisotropic method for fine finishing of reduction metal material according to claim 7, which is characterized in that described
The control moving range of rolled piece lengthwise position controller is 0 ~ 1000mm.
9. a kind of anisotropic method for fine finishing of reduction metal material according to claim 7, which is characterized in that described
The control moving range of rolled piece traverse feed controller is 1 ~ 1000mm.
10. a kind of anisotropic method for fine finishing of reduction metal material according to claim 7, which is characterized in that institute
Method is stated suitable for duo mill, 4 roller mills or multi-roll mill.
