Ginseng Figure 1 shows that the structural representation of solid aluminum section bar in the embodiment of the invention, and in figure, aluminium section bar long measure is mm.
Calculate the sectional area F of aluminium section bar
aluminiumwith aluminium section bar circumscribed circle diameter D
outward, as sectional area F in the present embodiment
aluminium=212.9mm
2, aluminium section bar circumscribed circle diameter D
outward=43.86mm.
According to following table and in conjunction with the range of work, require to be: F
aluminium>=F
aluminium min, and D
outward≤ D
outer maxselect base and optional equipment.
As having in the present embodiment 500T, 800T optional.Further optimize, obtain list:
Finally select the scheme 3 of 84.95% correspondence that lumber recovery is the highest.
The calculating of extruding force:
P＝11.775×[(D/d)

Wherein, P is extrusion pressure, and D is recipient interior diameter, the equivalent diameter that d is aluminium section bar, σ
btensile strength for material under extrusion temperature.
Therefore P=11.775 in present embodiment * [(125/16.46)
1/2-0.8] * 125
2* 16.2=5829.21KN
Be converted into tonnage: about 595T.
Due to P < specified tonnage 800T, equipment is selected to meet the requirements, and theory and technology is feasible.
Shown in structure ginseng Fig. 2 of extrusion die, comprise mould 1, die-cushion 2, front ring 3, rear ring 4, protection backing plate 5, forebay 6, die holder 7, die sleeve 8, scissors 9, recipient 10.
Solid mould sized data design specifically comprises:
1). select base and selection equipment
According to above can be calculated recipient interior diameter D
0=125mm, ingot blank size: D
d* L
d=Φ 120 * 400, extrusion ratio λ=57.61.
2). the calculating of module and mould form factor
Shown in ginseng Fig. 3, from following table, choose H2=100, H3=60, H1=30.
Shown in ginseng Fig. 4, from following table, can determine d1=165mm, d2=175mm, h1=12mm, h2=30mm.
3). definite extrusion ratio λ=57.61 < λ of shape size in mould
mAX=82, therefore do not need porous extruding.
Determine mold hole dimension (shown in ginseng Fig. 5):
Section bar appearance and size formula: Ak=Am+ (1+C

The actual wall thickness place size that wherein Sk is nib, Sm is the nominal size of section bar wall thickness, C
2for wanting coefficient of discharge, aluminium alloy is generally got to 0.05～0.15, the design gets 0.10, △
2overgauge for section bar wall thickness, calculates:
Sk＝3+0.25+0.10＝3.35mm。
4). hole shape is determined mould endface position
Because this section bar is for waiting section bar of wall thickness, therefore the geometric center of gravity of section bar is in the calculating of putting the center pressure center of mould, shown in ginseng Fig. 6.Calculating Center of Pressure is X
0=0, Y
0=6.32.
5). determining of land length
Because being waits wall thickness section bar, therefore calibrating strap length hg is equal everywhere, h is got in this design
g=5mm.
6). hinder angle
Due to h
g≤ 15mm, does not hinder angle therefore do not adopt.
The extrusion die of the present invention's design is after the check of mould intensity, and in the time of 500 ℃, the yield strength of 4Cr5MoSiV1 is 1025MPa, much larger than the size of equivalent stress, so mould intensity is qualified.
By above-mentioned embodiment, can be found out, the structure of extrusion of solid aluminum section bar of the present invention is simple, extruding efficiency is high, and mould manufacturing method is simple.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
