Description
Technical field
The present invention relates to a kind of extruding die for aluminum shaped material, more particularly to a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile extends the system of mould
Make method.
Background technology
With the fast development of aluminium profile market, it is raw material come instead of original its that increasing product uses aluminium alloy
Its material, so that reduces cost and raising durability.In recent years, the development of large aluminum alloy profiles is especially noticeable, in order to
This market demand trend is adapted to, each state is all in heavy type extruder or the heavy section extrusion line of speeding up the construction.But China's mesh
Preceding large-size extruder number of units is few, along with extruding high cost, so people often extrude ultra-wide section bar with small tonnage extruder.
As shown in figure 1, the extruding die for aluminum shaped material commonly used is made up of preceding flow-guilding mold 1 ' and pattern 2 '；Preceding flow-guilding mold 1 ' is provided with feed point
Discharge orifice 11 ', sets section bar nib 21 ' and discharge opening 22 ', this mould feed tap hole 11 ' and type commonly used on pattern 2 '
The faying face of material nib 21 ' is opened on preceding flow-guilding mold 1 ' and the faying face of pattern 2 ', and mould easily produces shake, in extrusion process easily
The false joint phenomenon of appearance, and mold use short life.
The content of the invention
It is an object of the invention to provide a kind of adding for ultra-wide Extrusion Process of Aluminum Alloy Profile extension mould for eliminating false joint phenomenon
Work method.
To achieve the above object, technical solution of the invention is：
The present invention is the improved structure that a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile extends mould, and it is made up of preceding flow-guilding mold and pattern；
Feed tap hole and section bar nib are provided with described preceding flow-guilding mold, feed tap hole is connected with section bar nib；Described pattern
Preceding flow-guilding mold one end is fixed on, the discharge opening of pattern is connected with the section bar nib on preceding flow-guilding mold.
Sky tool bore, preceding discharge opening are additionally provided with described preceding flow-guilding mold；Described feed tap hole, section bar nib, empty knife
Hole, preceding discharge opening are sequentially communicated, the aperture of the aperture more than section bar nib of feed tap hole, section bar nib, empty tool bore, preceding discharging
Hole increases successively, and the aperture of pattern discharge opening is gone forward the aperture of discharge opening more than preceding flow-guilding mold.
Less than chamber size in its section material section, feed tap hole needs extension to the port size of described feed tap hole.
The present invention is the manufacture method that a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile extends mould, and it is comprised the following steps：（1）Use milling machine
By the feed tap hole milling on preceding flow-guilding mold into straight hole, upper and lower size is equally big；（2）With the section bar of flow-guilding mold before linear cutter
Nib；（3）At the aperture of manufactured extension angle part is welded on preceding flow-guilding mold feed tap hole again, aperture is formed
The feed tap hole of the big extension in small and inner chamber；（4）With the empty tool bore on flow-guilding mold before electrical discharge machining, preceding discharge opening；（5）With
Discharge opening on electrical discharge machining pattern.
After using such scheme, because discharge opening and section bar nib are opened in preceding flow-guilding mold and pattern knot by the present invention respectively
On conjunction face, and interconnected feed tap hole and section bar nib are opened up in preceding flow-guilding mold, change traditional design, feed water conservancy diversion
Hole design is designed in lower mould in upper mould, pattern, separately laminating assembling, so as to avoid mould shake in extrusion process, is eliminated
Easily there is the phenomenon of false joint in small board production ultra-wide section in extrusion process, and the yield rate of product is higher, and equipment capacity is also big
Improve greatly, and mold use is lasted a long time.
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.

Specific embodiment
First, mould
As shown in figs 2-4, the present invention is the improved structure that a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile extends mould, and it is by preceding water conservancy diversion
Mould 1 and pattern 2 are constituted.
Feed tap hole 11, section bar nib 12, empty tool bore 13, preceding discharge opening 14 are provided with described preceding flow-guilding mold 1, it is described
Feed tap hole 11, section bar nib 12, empty tool bore 13, preceding discharge opening 14 be sequentially communicated, the aperture of feed tap hole 11 is more than
The aperture of section bar nib 12, section bar nib 12, empty tool bore 13, preceding discharge opening 14 increase successively.Described feed tap hole 11
The size of aperture 111 is less than its size of section material section inner chamber 112.
Described pattern 2 is fixed on the one end of preceding flow-guilding mold 1, the section bar nib on the discharge opening 21 of pattern 2 and preceding flow-guilding mold 1
12 connections.Aperture of the aperture of the described discharge opening 21 of pattern 2 more than the preceding discharge opening 14 on preceding flow-guilding mold 1.
As shown in figure 5, in the present embodiment, aluminium alloy extrusions is π fonts, and in order to increase flow velocity, can be by aluminium alloy extrusions π
Four arms of angle do it is larger.
Operation principle of the invention：
Feed tap hole 11 is flowed on feed the past flow-guilding mold 1, is gone out from discharge opening 21 after the extrusion forming of section bar nib 12
Material.Because feed tap hole 11 and section bar nib 12 are all arranged in preceding flow-guilding mold 1, feed will not be to preceding flow-guilding mold 1 and pattern 2
Faying face produce impact, therefore, the present invention will not occur jitter phenomenon, produce false joint.
2nd, processing method：
Because preceding flow-guilding mold 1 of the invention is in processing, because feed tap hole 11 is an extending bore, feed tap hole
11 size of aperture 111 need to be classified as two sections of processing less than its size of inner chamber 112 of section material section.
The present invention is the manufacture method that a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile extends mould, and it is comprised the following steps：
（1）As shown in fig. 6, with milling machine by the milling of feed tap hole 11 on preceding flow-guilding mold 1 into straight hole, upper and lower size is the same
Greatly；
（2）Again with the section bar nib 12 of flow-guilding mold 1 before linear cutter；
（3）As shown in fig. 7, the feed tap hole 11 being again welded on manufactured angle part 11B on preceding flow-guilding mold 1
At the 11A of aperture, the feed tap hole 11 of the extension that aperture is small and inner chamber is big is formed；Described angle part 11B is annular construction member, its
Cross section is triangular in shape；
（4）With the empty tool bore 13 on flow-guilding mold before electrical discharge machining 1, preceding discharge opening 14；
（5）With the discharge opening 21 on electric spark processing type mould 2（As shown in Figure 2）.
As shown in figure 8, the bearing capacity in order to strengthen the end face of feed tap hole 11, and the enlarging line of angle part 11B is extended
To the bottom surface of straight hole 11A so that the bottom of angle part 11B can act against the bottom of straight hole 11A.
Emphasis of the invention is that：Feed tap hole and section bar nib are set in preceding flow-guilding mold.
The above, only present pre-ferred embodiments, therefore the scope of present invention implementation can not be limited with this, i.e., according to
The equivalence changes that scope of the present invention patent and description are made and modification, all should still belong to the model that patent of the present invention covers
In enclosing.
