Lead portion.
Summary of the invention
It is an object of the invention to illustrate a kind of rolling device, the longevity of the length of roller can be realized with simple means
Life.
According to the present invention, the feature for passing through the characteristic of claim 1 for the rolling device being initially mentioned, the purpose
It realizes.By in axial direction changeably Positioning rollers, the guide surface that work along axial direction can be compensated via roller is readjusted
Abrasion.
It is provided in rolling device according to the present invention, roller extrudes workpiece by playing the cavity plate of molding.Preferably,
Here, cavity plate is just immediately follows arranged in after the roll gap of roller.In this arrangement, guide surface lateral or along axial side
To progress adjust thus it is similarly advantageous because can ensure that accurate centering of the workpiece relative to cavity plate.Roller as a result,
Axial adjustable allows to adjust width and the position of roll gap.
For the same reason, provided in generally preferable rolling device according to the present invention, at least one, especially two
A roller equally can be radially adjusted.
In simple and particularly suitable implementation of the invention, each roller in roller, which has, in axial direction to be made
Use the guide surface on workpiece.Two rollers can construct especially substantially mirror symmetricly.
It is frequently advantageous that, each roller in roller in axial direction can changeably be determined by means of regulating device
Position makes it possible to realize width and the position for comprehensively adjusting roll gap.
It is provided in embodiment that is of the invention simple and being reliably achieved, regulating device includes in a limiting fashion really
The matching piece of scale cun limits axial position of the roller on axis by means of the matching piece.Here, matching piece is formed in axis
On corresponding roller along the axial backstop for limiting positioning.At this point, by providing one group of cooperation that accordingly close spacing is classified
Part can realize the width of roll gap and/or readjusting for position with the cost of very little.
In alternative embodiment of the invention, regulating device may also include the stop mechanism that can infinitely adjust, from
And it can realize the arbitrary or continuous positioning of axis.Stop mechanism for example can include adjusting nut in a simple manner.
In general, advantageously, at least the core area of workpiece is when entering in roll gap with the state of operative liquid.This permits
Perhaps the particularly advantageous tissue of especially low roll-force and the workpiece for causing to form and cool down herein in connection with the molding due to cavity plate
Structure.The state of operative liquid is understood as herein, the material of workpiece is in the temperature in the melting zone of corresponding alloy.
Rolling device according to the present invention is particularly well suited to form the workpiece being made of non-ferrous metal.Further preferably
Ground, workpiece are made of light metal, and are particularly preferably made of magnesium alloy and/or aluminium alloy.Especially magnesium alloy and/or aluminium close
Gold with good result caused by the combination that cavity plate squeezes with the state of operative liquid.This is particularly suitable for roll gap by means of root
According to adjusting feasible program of the invention accurately centering into cavity plate.
Additional advantages and features are obtained from embodiment described below and dependent claims.
Detailed description of the invention
Illustrate a preferred embodiment of the present invention below and it is further elaborated by attached drawing.Wherein:
Fig. 1 shows the partially schematic section view of rolling device according to the present invention, wherein the roller axle of roller
Line is in section plane；
Fig. 2 shows the general views spatially of the rolling device of Fig. 1；
Fig. 3 shows the partially schematic section view of rolling device according to the present invention, wherein the roller axle of roller
Line is stretched perpendicular to section plane.
Specific embodiment
The rolling device of embodiment according to the present invention includes the first roller 1 and the second roller 2, they are supported on bracket 11
In.Roller 1,2 constructs substantially mirror symmetricly and is respectively provided with classification section 1a, 1b, 2a, 2b of different-diameter.
Each roller in roller 1,2 is assemblied on the axis 3,4 being driven.Axis 3a, 4a opposite rotation of the axis 3,4 around axis
Turn.
Here, the roller faces 5,6 of section 1a, 2a of the smaller diameter of roller 1,2 radially to work are radially
Direction is opposite and sets.
In addition, the guide surface 7,8 in axial direction to work is in axial direction opposite and sets.Guide surface be configured to roller 1,
The side of section 1b, 2b of 2 larger diameter.
In short, by the roller faces 5,6 that radially work and along the guide surface 7,8 that axial direction works be limited to laterally by
To limitation or closure roll gap 9, workpiece 10 transports through the roll gap by roller turn.
It is immediately just disposed with cavity plate 12 after the most narrow position of roll gap 9, extrudes or squeeze workpiece by the cavity plate
For forming.It is the outlet 13 for guiding and cooling down the workpiece squeezed out after cavity plate 12.
Workpiece is preferably entered in roll gap with the state of operative liquid.This is at least suitable for the core area of workpiece, wherein
It may according to circumstances be had been cured with technological parameter, fringe region.Preferably melted in material to be extruded with same heat
And reach the state of the operative liquid after being poured.
Because the guide surface 7,8 being axially directed at roller faces 5,6 and can draw with 10 CONTACT WITH FRICTION of workpiece
It is lost at guide face 7,8.
In order to reassure the lateral boundaries of roll gap 9 after loss, according to the present invention, roller 1,2 can be filled by adjusting
14 are set in axial direction movably to be positioned.Regulating device 14 includes matching piece 15,16 on each axis in axis 3,4,
Corresponding roller 1,2 is after in axial direction shifting on axis against the matching piece.Selectively determine size matching piece 15,
16 recline in itself is fixedly placed on backstop 17,18 on axis 3,4.
Matching piece has the size limited, to limit axial position of the roller on its axis by correspondingly selection size
It sets.The roller 1,2 so positioned is held against the clamping of matching piece 15,16 by clamp system 19,20 respectively.In the embodiment
In, regulating device 14 includes clamp system 19,20 and matching piece 15,16.
Unshowned is the adjustability equally existed of axis 3,4 or roller 1,2 radially.This known ground is via axis
3, the positioning of 4 rotating support is realized.Generally speaking, thus roll gap can also be adjusted in terms of its height and its radial position
It is quasi-.It can especially therefore ensure that workpiece 10 centrally passes through roller 1,2 before cavity plate just.
