Description
Technical field
The utility model belongs to section bar hot extrusion technical field, more particularly to extrudes different wall tube and pipe of aluminium alloy
Hot-extrusion mold.
Background technology
With the development of aluminum profile industry, the purposes of aluminium section bar is more and more extensive, and the aluminium section bar demand of wherein tubing is more next
Bigger.The pipe profile of same manufacturer production often has different dimension serieses at present, it means that despite production same class
Pipe section bar, needing to develop multiple supporting moulds carries out extruding production.Especially for some small lots, the series of multi items
For changing product, one side die cost is greatly improved, and the care and maintenance simultaneously for the later stage of mould is also considerably increased
Production cost.While it is noted that the failure of pipe class extrusion die is usually by fracture and the work belt wear of shunting bridge
Seriously, mould occurs bullet change to lead to not ensure that precision causes.
Therefore the market demand for how to extend die life, increasing mould service efficiency, meet multi-varieties and small-batch becomes
For reducing a great problem of tubing aluminium section bar production cost.
Utility model content
For the deficiencies in the prior art, the utility model purpose is to provide a kind of pipe for extruding same aperture different wall
Class aluminium section bar with block insert type work the hot-extrusion mold with die.
The utility model includes the upper die and lower die for coaxially cooperating, in the centrally disposed cylindrical mould core of upper mould, described
Core rod is connected on upper mould by least three shunting bridgings for being arranged symmetrically in core rod periphery, and lower mould arranges the first bonding container and the
One nib；It is characterized in that arranging annular seating between first bonding container and the first nib of lower mould, lead on the annular seating
Cross that keyway is detachable to be coaxially disposed circular-patch, in centrally disposed second nib of the circular-patch, on the second nib
Side arranges annular working band, and the lower end of the core rod is arranged on the lower surface of annular working band, the annular working band straight
Footpath is little compared with the aperture of the second nib, and the aperture of second nib is little compared with the aperture of the first nib.
Can be connected by the way of routine between the utility model upper die and lower die, such as pass through pin connection.By coaxial mutual
The upper die and lower die of cooperation constitute master mold, arrange circular-patch in master mold, and lower mould is provided with a first larger nib of aperture,
The tubing of larger external diameter can be extruded, lower mould adopts the detachable setting circular-patch of keyway, beneficial to different second nibs of replacing
Aperture, the circular-patch of different-diameter annular working band, to produce different wall tubing tubing.
Utility model works principle：, using work band and lower mould split-type design, work band is positioned at ring for the utility model
In shape insert, circular-patch is connected with lower mould by keyway.When the pipe profile of same aperture different wall is extruded, can be according to wall thickness
Difference, independent design is carried out to circular-patch, due to simple structure, difficulty of processing is low for circular-patch, and re-molds phase
Than greatly reducing processing and manufacturing operation, so as to reduce die sinking cost.Further, since the particularity of Extrusion Process of Aluminum Alloy Profile, work
Higher hardness, corrosion resistance, surface smoothness is required with position than other positions of mould, using split-type design, can be right
Circular-patch carries out independent heat treatment, nitridation so as to more meet required standard, meanwhile, circular-patch takes small volume, can
Improve heat-treatment furnace, nitriding furnace service efficiency.The maintenance and repair difficulty of later stage mould can be also reduced for Split type die design.
The utility model adopts modular organization, it is easy to which combination dismounting, interchangeability are strong, are particularly well-suited to small lot, many product
The tandem product that plants.
Further, the utility model is symmetrical arranged four keyways on the annular seating of lower mould, and each keyway is along the axle of lower mould
Line direction is in up big and down small taper, arranges four connecting keys coordinated with keyway in circular-patch periphery.The design is not only sharp
In circular-patch is changed, also facilitate the production of lower mould and circular-patch.With four bonded, positioning standards between insert and annular seating
Really, assembly and disassembly is simple, and actual operability is stronger, while insert is not susceptible to relative movement, advantageously ensures that extruded product
Quality.
The shunting bridge is six, defines six tap holes between adjacent shunting bridge, and tap hole cross section is fan
Shape, shunting bridge section are in water-drop-shaped.
Six circumferentially symmetrical tap holes are set on upper mould, metal flow can be made evenly, reduce metal
Stream gets muddled probability, while tap hole is symmetrical, makes core rod uniform force, keeps stable, prevents flexural deformation.
Shunting hole shape is set to sector, consistent with pipe profile, equivalent to carrying out once similar thick deformation to ingot casting.Shunting
Water-drop-shaped is processed in bridge end, is easy to metal to flow into nib, reduces metal dead band under bridge, improves weldquality.

Specific embodiment
As shown in Fig. 1,2,3,4,5,6,7, the utility model is made up of coaxial upper mould 1, lower mould 2 and circular-patch 3.
In the centrally disposed cylindrical mould core 4 of upper mould 1, core rod 4 is by being arranged symmetrically in six shunting bridges 6 of 4 periphery of core rod
It is connected on mould 1, six tap holes 5 between adjacent shunting bridge 6, is defined, the cross section of tap hole 5 is sector（As schemed
Shown in 2）, the section for shunting bridge 6 is in water-drop-shaped（As shown in Figure 7）.
Lower mould 2 arranges the first bonding container 8 and the first nib 12, between first bonding container 8 and the first nib 12 of lower mould 2
Annular seating 10 being set, four keyways 7 being symmetrical arranged on annular seating 10, each keyway 7 is in up big and down small along the axis direction of lower mould 2
Taper（As shown in Figure 4）.
The periphery of circular-patch 3 is symmetrical arranged four connecting keys 9 coordinated with keyway 7, and circular-patch 3 is cooperatively disposed to
In annular seating 10（As shown in Figure 1）.In centrally disposed second nib 11 of circular-patch 3, ring is set in 11 top of the second nib
Shape work band 13.
The lower end of core rod 4 is arranged on lower surface of the annular working with 13, annular working with 13 diameter compared with the second nib
11 aperture is little, and the aperture of the second nib 11 is little compared with the aperture of the first nib 12（As shown in Figure 1）.
As the use environment of upper mould 1 and lower mould 2 and the use environment of circular-patch 3 have difference, required precision is different,
In die manufacture, circular-patch 3 separately can be produced and processed with lower mould 2, different Technologies for Heating Processing can be adopted to both
To meet its extruding environmental requirement, beneficial to the material cost for saving mould, also it is beneficial to during later stage mould maintenance and repair, can
Independent nitridation is carried out to circular-patch 3.
The production of pipe is can be applicable to mold, also apply be applicable to the production of square tube.
