Abstract
The present invention relates to a kind of thin-wall aluminum alloy tube-drawing molds, and including drawing mould core print and drawing external mold, the drawing mould core print is cylinder, rounding at feed inlet, chamfering radius R8；Drawing external mold outer diameter is in cone, and the diameter positioned at feed inlet direction is more than other end diameter；Drawing external mold internal diameter is provided with the work band that internal diameter is less than other positions, and the width for the band that works is 5mm.Present invention can ensure that the drawing quality of thin-wall aluminum alloy tubing, avoids the skidding of workpiece, pulls, the situation that surface luminous intensity is not up to standard, straightness is bad and tooling service life is short.
Description
Technical field
The present invention relates to a kind of drawing mould, especially a kind of thin-wall aluminum alloy tube-drawing mold.
Background technology
In the prior art, drawing mould can carry out drawing to metal pipe material workpiece, be played in workpiece drawing process
Vital effect.In general, drawing mould is made of drawing mould core print and drawing external mold, wherein draft tool core print is in cylinder
Shape, feed inlet set the rounding of R5, and in a ring, internal diameter is designed with the work band of 10mm to drawing external mold.In batch production, workpiece
The phenomenon that easily generation skids, pulls, surface luminous intensity is not up to standard, straightness is bad and tooling service life is short, this phenomenon is stranded
This field a very long time is disturbed, the processing method studied well always is never fully solved problem above.
Invention content
The object of the present invention is to provide a kind of drawing moulds, solve during thin-wall aluminum alloy tube-drawing, avoid work
The phenomenon that part skids, pulls, surface luminous intensity is not up to standard, straightness is bad and tooling service life is short.
The present invention particular technique content be：The thin-wall aluminum alloy tube-drawing mold include drawing mould core print and
Drawing external mold, the drawing mould core print is cylinder, and pipe internal diameter clearance fit, the drawing mould core print into
Rounding at material mouth, chamfering radius R8；Drawing external mold outer diameter is in cone, and the diameter positioned at feed inlet direction is more than the other end
Diameter；Drawing external mold internal diameter is provided with the work band that internal diameter is less than other positions, and the width for the band that works is 5mm；The drawing
Mold external mold internal diameter and drawing mould core print external diameter surface carry out Du Chrome processing.
The present invention is perfect to the redesign of drawing mould external mold, drawing mould core print, and the change for the band that works reduces workpiece
With the frictional force of mold, the finish of lifting workpieces, the outer diameter cylindrical face of mold external mold is changed to circular conical surface and promotes clamping mould taboo
Degree of pluging with molten metal, avoids having skidded in processing journey, obscission, and the rounding R5 at drawing mould core print feed inlet makes R8 into, can subtract
The clamping stagnation that occurs in small workpiece fill process, gouge phenomenon.While mold finish can be increased by carrying out process of surface treatment
The hardness of the mold of reinforcing, and prolong the service life.Therefore, present invention can ensure that the drawing quality of thin-wall aluminum alloy tubing,
It avoids the skidding of workpiece, pull, the situation that surface luminous intensity is not up to standard, straightness is bad and tooling service life is short.
Description of the drawings
Fig. 1 is the operating diagram of the present invention；
Fig. 2 is mold external mold schematic diagram of the present invention；
Fig. 3 is drawing mould core print schematic diagram of the present invention.
Specific embodiment
As shown in the figure, thin-wall aluminum alloy tube-drawing mold includes drawing mould core print 1 and drawing external mold 2, the drawing
Draft tool core print 1 is cylinder, and 3 internal diameter clearance fit of tubing, rounding at the feed inlet of the drawing mould core print 1,
Radius of circle is R8；2 outer diameter of drawing external mold is in cone, and the diameter positioned at feed inlet direction is more than other end diameter；Outside drawing
2 internal diameter of mould is provided with the work band that internal diameter is less than other positions, and the width for the band that works is 5mm；In the drawing mould external mold 2
Diameter and 1 external diameter surface of drawing mould core print carry out Du Chrome processing.
