Abstract
A production method of a high-rib opening section bar belongs to the field of section bar machining, particularly a production method of a high-rib opening aluminium alloy section bar and a mold technology. According to the production method, extrusion production is carried out after an aluminium alloy bar subjected to homogenization treatment, an extrusion container and a mold are respectively heated; and the production method is characterized in that a pre-running mold with an arched bypassing bridge is used for production in the extrusion process. The production method has the advantages of being capable of well solving the problem that a cantilever part of the mold is crushed and cracks prematurely in the extrusion process, well prolonging the service life of the mold and particularly suitable for extruding the high-rib opening section bar.
Description
Technical field
The invention belongs to section bar manufacture field, the particularly production method of high muscle opening class aluminium alloy extrusions, and Tool and Die Technology.
Background technology
Aluminium alloy extrusions has use, the huge market demand, particularly high muscle opening class section bar because it has a series of superiority in a lot of fields.For opening profile, all adopt water conservancy diversion mould to produce in the market, but in actual production, find to adopt water conservancy diversion mould production effect bad for high muscle opening class section bar, main cause is that water conservancy diversion mould bracketed part is long, the stressed complexity of mould bracketed part in extruding process, bracketed part is easy to fracture and pressure is collapsed), cause the initial failure of mould.
Summary of the invention
The object of the invention is to provide a kind of production method of high muscle opening class section bar, to solve existing water conservancy diversion mould mould bracketed part easy fracture and press the problem collapse in extruding process.
The present invention includes after the aluminium alloy bar of processing through homogenising, recipient and the preheating of mould difference, push production, it is characterized in that adopting the vacation shunting mould with arch shunting bridge to produce in described extrusion process.
The vacation shunting mould with arch shunting bridge of the present invention is mainly comprised of upper die and lower die, on patrix, be distributed with tap hole and shunting bridge, the cambered surface arching upward to top centered by the bottom surface of shunting bridge, counterdie is provided with seam chamber, work band and the empty cutter matching with tap hole.
The present invention is the false divergent die without core, owing to increasing shunting bridge in cantilever one end, make the stressed of bracketed part become simply supported beam by original cantilever beam, stressed more balanced, the force-bearing situation of the domes of shunting bridge lower end is similar to static determinacy arch, from structural mechanics, in forming process, mould bridge lower end is not only subject to axial shearing force, also be subject to compression radially, the force-bearing situation of mould bridge is improved simultaneously, has reduced mould bridge and has cracked, the phenomenon of fracture, so played the effect significantly improving to the service life of mould.
The present invention can solve well mould bracketed part in extrusion process and press too early the problem of collapsing and rupturing, and can extend preferably the service life of mould.Be particularly suitable for extruding high muscle opening class section bar.
In addition, the preheat temperature of bar of the present invention is 490 ℃, and the preheat temperature of recipient is 450 ℃, and the preheat temperature of mould is 470 ℃.

The specific embodiment
The high muscle opening of the present invention class section bar as shown in Figure 1, section is mountain font, and rib height is larger, belongs to high muscle opening class part.
One, for the production of the mould with the high muscle opening of the font of going up a hill class section bar:
As shown in Figure 7, the vacation shunting mould that has an arch shunting bridge is mainly comprised of patrix 1 and counterdie 2.
As shown in Figure 2,3, 4, be distributed with three tap holes 11 on patrix 1, be correspondingly provided with two shunting bridges 12, each shunts the cambered surface 13 arching upward to top centered by the bottom surface of bridge 12.
As shown in Figure 5,6, counterdie 2 is provided with the font seam chamber, mountain 21 of matching with mountain font tap hole 11, work and is with 22 and empty cutter 23.
Two, take the high muscle opening class section bar concrete technology that 6063T5 aluminium alloy is example:
6063T5 aluminium alloy belongs to Al-Mg-Si and is associated gold, and except aluminium, all the other compositions are as follows:
Si：0.20%-0.6%、Fe：0.35%、Cu：0.10%、Mn：0.10%、Mg：0.45%-0.9%、Cr：0.10%、Zn：0.10%、Ti：0.10%。
1,6063T5 aluminium alloy strand is carried out to homogenizing annealing processing: annealing temperature is 560 ℃, insulation 6h, is cooled fast to 250 ℃ with powerful air-flow afterwards, and cooling velocity is 60 ℃/min, stops afterwards 0.5h, then water is cooled to 50 ℃.Homogenising makes the institutional framework of material even after processing, and is conducive to improve the life-span of mould and the surface quality of product in extruding process.
2,, by blank heating to 490 ℃, recipient is heated to 450 ℃, by upper and lower mould matched moulds, and mold heated to 470 ℃, the temperature of the section bar port of export is not less than 500 ℃.
3, strand, under the pressure of recipient, is divided into three parts after the shunting bridge of flowing through, and passes through afterwards the seam of HTHP high vacuum in the seam chamber 21 of counterdie, then the work band 22 of flowing through, and from empty cutter 23, extrudes mountain font section bar semi-finished product.
4, excise half-finished head and afterbody, carry out solution treatment and artificial aging and process (200 ℃/2.5 h).What solution treatment adopted is air-cooled online.
5, by the actual size intercepting of workpiece, obtain the high muscle opening class section bar that section is mountain font.
