Description
Technical field
The utility model relates to a kind of extruding die for aluminum shaped material, particularly relates to the modified node method of a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile expansion mould.
Background technology
Along with the fast development of aluminium profile market, increasing product adopt aluminium alloy be raw material to replace other original material, thus reduce costs and improve durability.In recent years, the development of large aluminum alloy profiles is especially noticeable, and in order to adapt to this market demand trend, each state is all at heavy type extruder or the heavy section extrusion line of speeding up the construction.But the current large-size extruder number of units of China is few, it is high to add extruding cost, so people are often with little tonnage extruder extruding ultra-wide section bar.As shown in Figure 1, the extruding die for aluminum shaped material commonly used is made up of front flow-guilding mold 1 ' and pattern 2 '; Front flow-guilding mold 1 ' is provided with feed tap hole 11 ', pattern 2 ' arranges section bar nib 21 ' and discharge opening 22 ', this mould feed tap hole 11 ' commonly used and the faying face of section bar nib 21 ' are opened on front flow-guilding mold 1 ' and pattern 2 ' faying face, mould easily produces shake, the false joint phenomenon easily occurred in extrusion process, and the mold use life-span is short.
Utility model content
The purpose of this utility model is to provide a kind of modified node method eliminating the ultra-wide Extrusion Process of Aluminum Alloy Profile expansion mould of false joint phenomenon.
For achieving the above object, technical solution of the present utility model is:
The utility model is the modified node method of a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile expansion mould, and it is made up of front flow-guilding mold and pattern; Be provided with feed tap hole and section bar nib in described front flow-guilding mold, feed tap hole is communicated with section bar nib; Described pattern is fixed on front flow-guilding mold one end, and the discharge opening of pattern is communicated with the section bar nib on front flow-guilding mold.
Described front flow-guilding mold is also provided with sky tool bore, front discharge opening; Described feed tap hole, section bar nib, empty tool bore, front discharge opening are communicated with successively, the aperture of feed tap hole is greater than the aperture of section bar nib, section bar nib, empty tool bore, front discharge opening increase successively, and the aperture of pattern discharge opening is greater than front flow-guilding mold and goes forward the aperture of discharge opening.
The port size of described feed tap hole is less than its section material section inner cavity size, and feed tap hole needs expansion.
After adopting such scheme, because discharge opening and section bar nib are opened on front flow-guilding mold and pattern faying face by the utility model respectively, and in front flow-guilding mold, offer the feed tap hole and section bar nib that are interconnected, change traditional design, the design of feed pod apertures is at patrix, pattern design is at counterdie, separately to fit assembling, thus in extrusion process, avoid mould shake, eliminate the phenomenon that false joint easily appears in extrusion process medium and small board production ultra-wide section, the yield rate of product is higher, and equipment capacity also improves greatly, and the mold use life-span is longer.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Detailed description of the invention
As shown in figs 2-4, the utility model is the modified node method of a kind of ultra-wide Extrusion Process of Aluminum Alloy Profile expansion mould, and it is made up of front flow-guilding mold 1 and pattern 2.
Feed tap hole 11, section bar nib 12, empty tool bore 13, front discharge opening 14 is provided with in described front flow-guilding mold 1, described feed tap hole 11, section bar nib 12, empty tool bore 13, front discharge opening 14 are communicated with successively, the aperture of feed tap hole 11 is greater than the aperture of section bar nib 12, and section bar nib 12, empty tool bore 13, front discharge opening 14 increase successively.Aperture 111 size of described feed tap hole 11 is less than its inner chamber 112 size.
Described pattern 2 is fixed on front flow-guilding mold 1 one end, and the discharge opening 21 of pattern 2 is communicated with the section bar nib 12 on front flow-guilding mold 1.The aperture of described pattern 2 discharge opening 21 is greater than the aperture of the front discharge opening 14 on front flow-guilding mold 1.
As shown in Figure 5, in the present embodiment, aluminium alloy extrusions is π font, and in order to increase flow velocity, that four of an aluminium alloy extrusions π arm of angle can be done is larger.
Operation principle of the present utility model:
On feed the past flow-guilding mold 1, feed tap hole 11 flows into, from discharge opening 21 discharging after section bar nib 12 is extruded.Because feed tap hole 11 and section bar nib 12 are all arranged in front flow-guilding mold 1, feed can not produce impact to the faying face of front flow-guilding mold 1 and pattern 2, therefore the utility model jitter phenomenon can not occur, and produces false joint.
Processing method of the present utility model:
Before the utility model, flow-guilding mold 1 is adding man-hour, and because feed tap hole 11 is an extending bore, aperture 111 size of feed tap hole 11 is less than its inner chamber 112 size, need be divided into two sections of processing.(1) as shown in Figure 6, first, with milling machine, feed tap hole 11 milling is become straight hole, upper and lower size is equally large; (2) the section bar nib 12 of flow-guilding mold 1 before linear cutter is used again; (3) as shown in Figure 7, more manufactured angle part 11B is welded on 11A place, forms the feed tap hole 11 of required form.
As shown in Figure 8, in order to strengthen the bearing capacity of feed tap hole 11 end face, and the enlarging line of angle part 11B is extended to the bottom surface of straight hole 11A, the bottom of angle part 11B can be leaned in the bottom of straight hole 11A.
Emphasis of the present utility model is just: in front flow-guilding mold, establish feed tap hole and section bar nib.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
