Abstract
The utility model belongs to mould applications, more particularly to a kind of extrusion die of sheet material.The sheet material coarse-grain floor height that the extrusion die of existing sheet material manufactures, average particle size height are not uniform enough.The utility model provides a kind of extrusion die of sheet material, including die face（1）With special die-cushion（2）, the die face（1）With the special die-cushion（2）It is fixedly connected, the die face（1）In be provided with diversion cavity（3）, work band（4）It is arranged on diversion cavity（3）Below, described diversion cavity（3）Shape with processing sheet material it is consistent.The coarse-grain layer of the sheet material manufactured by extrusion die provided by the utility model is 0.4 0.5mm, and average particle size is within 150um, and very average.
Description
Technical field
The utility model belongs to mould applications, more particularly to a kind of extrusion die of sheet material.
Background technology
Sheet material general more than the 1mm of coarse-grain layer, the general 250um of average particle size that the extrusion die of existing sheet material makes with
Above and not enough uniformly, such sheet material exists heterochromatic after there is in oxidizing process, and main cause is that granularity is high, no
Uniformly, all can more or less there is corrosion phenomenon, but because not enough uniformly, different places, extent of corrosion is different, thus
Cause heterochromatic, one is attractive in appearance to influence, two come use to sheet material there is also certain influence.
Utility model content
Technical problem to be solved：
The sheet material coarse-grain floor height that the extrusion die of existing sheet material manufactures, average particle size height are not uniform enough.
Technical scheme：
In order to solve problem above, the utility model provides a kind of extrusion die of sheet material, including die face 1 and die for special purpose
Pad 2, the die face 1 are fixedly connected with the special die-cushion 2, and diversion cavity 3 is provided with the die face 1, and work band 4 is arranged on water conservancy diversion
Behind chamber 3, the shape of described diversion cavity 3 is consistent with the sheet material of processing.
The depth of described diversion cavity 3 is 15-20mm.
Described work band 4 length is 0.6-0.7 times of wall thickness.
Die-cushion discharging opening 7 is provided with described special die-cushion 2.
1 grade of empty knife 5 and 2 grades of empty knives 6 are followed successively by after described work band.
The special die-cushion 2 is connected by combined screw and combination pin and die face 1.
Beneficial effect：
The coarse-grain layer of the sheet material manufactured by extrusion die provided by the utility model is 0.4-0.5mm, average particle size
Within 150um, and it is very average.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is elaborated below by drawings and examples.
As shown in figure 1, a kind of extrusion die of sheet material, including die face 1 and special die-cushion 2, the die face 1 and described special
Die-cushion 2 is fixedly connected, and diversion cavity 3 is provided with the die face 1, and work band 4 is arranged on behind diversion cavity 3, described diversion cavity 3
Shape is consistent with the sheet material of processing.
Diversion cavity 2 using and sheet material just as structure, such effect is section bar in shaping the pressure of each point is basic
It is identical.
The depth of described diversion cavity 3 is 15-20mm, and the depth as shallow of diversion cavity 3, more a step make section bar each in shaping
The pressure of point is identical.
Described work band 4 length is 0.6-0.7 times of wall thickness.Using short and equal work band, this can make work band
The frictional force of section bar each point in extruding is of substantially equal.
The section bar squeezed out by the mould of this structure, its coarse-grain layer is than relatively thin, only 0.4-0.5mm, and
Grain size is very uniform, is reduced afterwards in oxidizing process heterochromatic.
Embodiment 1
Sheet material is square, and described diversion cavity 2 also uses square, depth 20mm, and the length for the band that works is the 0.7 of wall thickness
Times.After extruding, water cooling, timeliness, the thick crystal layer thickness for squeezing out sheet material is 0.48mm, grain size 123um.
Embodiment 2
Sheet material is square, and described diversion cavity 2 is also square, depth 15mm, and the length for the band that works is 0.6 times of wall thickness,
After extruding, water cooling, timeliness, the thick crystal layer thickness for squeezing out sheet material is 0.43mm, grain size 136um.
Embodiment 3
Sheet material is circle, and described described diversion cavity 2 is also square, depth 18mm, and the length for the band that works is wall thickness
0.6 times, after extruding, water cooling, timeliness, the thick crystal layer thickness for squeezing out sheet material is 0.6mm, grain size 178um.
Although the utility model is disclosed as above with preferred embodiment, they are not for limiting the utility model
, it is any to be familiar with this those skilled in the art, in the spirit and scope for not departing from the utility model, it can make various changes or retouch from working as,
What therefore the scope of protection of the utility model should be defined by claims hereof protection domain is defined.
