Description
Technical field
The present invention relates to Extrusion Process of Aluminum Alloy Profile technical fields, more particularly, to a kind of high power tooth radiator extrusion die and extruding
Technique.
Background technique
Aluminium alloy high power tooth radiator is since its number of teeth is excessive, tooth is high excessive, so that between the height and adjacent fins of fin
The proportionality coefficient of gap is excessive, this general proportionality coefficient is more than that 16 radiator is referred to as high power tooth radiator, traditional radiator
Die design schemes are no longer desirable for high power tooth radiator, otherwise will cause each fin in extrusion process and are fed insufficient unevenness
It is even, it is difficult to the flow velocity of balance control labor and materials.Traditional high power tooth radiator mould not can guarantee fin and substrate, radiator center
It is balanced with the feed at edge, the phenomenon that not can guarantee the intensity of fin root, broken teeth may be generated, such that production effect
The problems such as rate is low, and extrudate product quality is not up to standard.
Summary of the invention
The purpose of the present invention is shortcoming in view of the above technology provide a kind of easy to process, easy to form, cost compared with
Low aluminium alloy high power tooth radiator extrusion die, also provides a kind of extrusion process, solves problems of the prior art.

Step C is evenly heated mold by far-infrared heating stove；
Step D, the pressurizing unit of extrusion cylinder promote aluminium alloy cast rod to high power tooth radiator mould, aluminium alloy cast rod from
Extrusion forming goes out extrusion in mold；
Step E, mechanical property is not reached requirement and the head that deformation occurs and tail portion excision；
Step F, slight to radiator base plate progress air-cooled, the type of cooling of fin is natural cooling；
Step G makees straightening processing to profile after cooling, profile is fixed on seven-roll Abramsen machine and is aligned, then scale
Sawing；
Step H finally carries out ageing treatment, mechanical property is made to reach requirement.
Preferably, in the step B, the mode of preheating is ladder heating, and casting rod head is heated to 480-500 DEG C, middle part
It is heated to 460-480 DEG C, Tail-heating is to 440-460 DEG C.
Preferably, in the step H, aging temp is 180 DEG C, and aging time is 7 hours.
Compared with the existing technology, a kind of high power tooth radiator extrusion die and extrusion process of the present invention, have with
Down the utility model has the advantages that the balance of fin and substrate feed has been fully considered on the design form of stock guide, in order to prevent at substrate
Labor and materials flow velocity is too fast, and stock guide has blocked substrate in the position of substrate；Original structure will cause fin feed unevenly, and this case
It takes and is parallel to the mode of base plate bottom stock guide is made to have blocked fin root completely, not will cause the offset of cantilever.Inclination
The high power tooth heat radiator fin of dispersed can increase the spacing of adjacent fins, reduce height and the adjacent fins gap of fin
Proportionality coefficient, so that a possibility that reducing burn failure, extends the service life of mold, saved cost.

Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood by concrete condition
Concrete meaning in the present invention.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in figures 1-8, a kind of high power tooth radiator extrusion die, including from top to bottom sequentially connected stock guide 1, on
Mould 2 and pad 3 are bolted between stock guide 1, upper mold 2 and pad 3.
Feed inlet 4 is equipped in the stock guide 1, guidance labor and materials enter in the die hole of upper mold 2, while also playing in protection
The effect of mould 2.4 upper surface of feed inlet of the stock guide 1 is in the shape of an " I ", and the lower end surface of feed inlet 4 is in rectangle, feed inlet 4
Inside forms two inclined surface 10, so that I-shaped mouth makes labor and materials abundance uniformly enter die hole 5 to rectangular opening transition.
I-shaped mouth shelters from strip-shaped hole 9 from top, and labor and materials flow velocity is too fast at radiator base plate 12 in order to prevent.
Through-hole 7 is equipped in pad 3, feed inlet 4, die hole 5 and through-hole 7 communicate, and die hole 5 includes the trapezoidal hole communicated and strip-shaped hole
9, it is fixed with several flase floors 8 to form heat radiator fin 11 in trapezoidal hole, forms radiator base plate 12 in strip-shaped hole 9.Item
Empty knife 6 three times is formed in the opposite side of upper mold 2 and pad 3 in shape hole 9, ensure that aluminum profile passes through, strengthen the service life of mold.
Flase floor 8 is along trapezoidal pore size distribution, inclined dispersed.
Labor and materials initially enter feed inlet 4, be formed with inside feed inlet 4 extension make to store inside stock guide 1 it is enough
Labor and materials.Since flow velocity is slower at fin, radiator base plate position is blocked at 1 charging of stock guide, to reduce
Flow velocity at substrate, while stock guide 1 has blocked fin root completely, not will cause cantilever (i.e. the heat radiator fins on both sides)
Offset.Labor and materials have a predeformation process in the extruding incipient stage, prevent from generating biggish pressure in extrusion process, play
Protect the effect of mold.The upper mold 2 is formed with die hole 5 with the opposite side of stock guide 1, in order to reduce the height of fin with it is adjacent
The fin design of die hole pass is inclination dispersed, does not do and change at substrate, can increase in this way by the proportionality coefficient of fin clearance
The intensity of big mold prevents fin offset from causing the unqualified of product.The opposite side of upper mold 2 and pad 3 is formed with radiator base
The knife empty three times of plate 12, allow aluminum profile safety by upper mold 2, power of not having an effect with mold plays enhancing mold
The effect in service life.Upper mold 2 is bolted with stock guide 1 and pad 3, forms squeezing for the high power tooth radiator of complete set
Compression mould.
A kind of high power tooth radiator extrusion process is included the following steps: using above-mentioned high power tooth radiator extrusion die
Step A, is surface-treated casting rod, removes casting hard shell and surface oxide layer using peeling machine, in order to avoid influence
Section quality；
Step B preheats the aluminium alloy cast rod handled well, and the mode of preheating is ladder heating, and casting rod head is heated to
480-500 DEG C, middle part is heated to 460-480 DEG C, and Tail-heating is to 440-460 DEG C, casting rod and mold adhesion in order to prevent, to it
Carbon dust is sprayed, is put into extruder extrusion cylinder；
Step C is evenly heated mold by far-infrared heating stove, and mould heating-up temperature is 470-490 DEG C；
The pressurizing unit of step D, extrusion cylinder are dissipated aluminium alloy cast rod to high power tooth with the extrusion speed of 1.8-2.5m/min
Hot device mold promotes, and aluminium alloy cast rod extrusion forming from mold goes out extrusion；
Step E, mechanical property is not reached requirement and the head that deformation occurs and tail portion excision；
Step F, extrudate online carry out radiator base plate 12 slight air-cooled, and the type of cooling of fin is that nature is cold
But, prevent fin deformation so that product is unqualified；
Step G makees straightening processing to profile after cooling, profile is fixed on seven-roll Abramsen machine and is aligned, then scale
Sawing, to obtain satisfactory length；
Step H finally carries out ageing treatment, mechanical property is made to reach requirement.Aging temp is 180 DEG C, aging time 7
Hour.Finished section bar is obtained, as shown in Figure 9.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
