Abstract
The utility model relates to a die set for aluminium alloy extrusion processing. An anteverted pyramid groove is arranged at the root side face of the needle front-end narrow slit of an upper mould in symmetrical. A needle rejection band in reverse convexity is arranged between the contiguous anteversion pyramid grooves. Multichannel flat tubes in aluminum alloys produced by the utility model conform to the GBn 222-84 standard, and satisfy the requirements of the special level standard of the US material and experiment association ASTMB221M-83 and the japanese industrial standard HiSH4100-1982.
Description
The utility model relates to a kind of aluminium alloy extruded die for processing, the extrusion modling of its suitable especially high accuracy, multichannel, thin-wall aluminum alloy flat tube.Constitute by patrix that disposes tap hole, pin front end and counterdie with seam chamber, belong to metal extrusion modling instrument.
Multichannel aluminum alloy flat tube, especially the thin-walled flat tube of duct wall thickness below 0.7mm, because the uniformity of wall thickness and seam all are difficult to guarantee, lumber recovery is lower in the making, have only minority manufacturer to grasp certain production technology abroad, but employed mould and corresponding technology, but unexposed always report.
The utility model provides a kind of suitable making channel wall thickness 0.7mm the mould of following multichannel aluminum alloy flat tube.
Full for flat tube conduit wall metal is filled, and improve its shaping and strengthen the seam ability.According to metal flow momentum law of minimum resistance and relevant theoretical.This mould has structurally been taked following technical measures.
Root side at the pin front end narrow slit of patrix is symmetrical arranged the pyramid groove that leans forward, and is the pin stopband of reverse projection in the adjacent configuration between the pyramid groove of leaning forward.
This mould is in making the aluminium alloy ingots hot extrusion molding process of multi-channel flat pipe, and the pyramid groove that leans forward plays the effect that the narrow slit place is gone in collections, water conservancy diversion metal, makes too soon because of flow velocity usually, is difficult for flowing into the metal of narrow slit, preferentially fills narrow slit.And adjacent leaning forward disposed the pin stopband that is reverse projection between the pyramid groove, hinder metal aptly and flow through from wire surface, and a part of metal of shunting is poured into the pyramid groove that leans forward, and enters smoothly in the narrow slit, increased the full amount of metal of narrow slit.
If tap hole length is extended to the 110-150% of pin front end overall with, the also corresponding lengthening in the seam chamber of counterdie, thus increasing metal inlet space, section bar both ends, the full result of more metal makes the moulding of section bar both ends easy.These measures have all promoted product moulding and have strengthened the seam ability.
Employing possesses the mould of above-mentioned technical characterictic, produce the aluminium alloy multi-channel flat pipe, its product meets the high-precision requirement in the GBn222-84 standard, satisfies the requirement of ASTMB221M-83 of American Society Testing and Materials and JIS JiSH4100-1982 particular stage standard.
Accompanying drawing is a structural representation of the present utility model, below in conjunction with accompanying drawing, and narration the utility model most preferred embodiment.Wherein, Fig. 1 is the front view of patrix, and Fig. 2 is its profile, Fig. 3 be A to view, Fig. 4 is the B-B cutaway view, Fig. 5 is the front view of counterdie, Fig. 6 is a profile.
Aluminium alloy extruded die for processing is made up of patrix (1) and counterdie (8).The tap hole (2) of patrix (1) extends to the 110-150% of pin front end (3) overall with, and corresponding lengthening is also made in the seam chamber (9) of counterdie (8).The root side of pin front end (3) narrow slit (5) of patrix (1), be symmetrical arranged the pyramid groove (4) that leans forward, and be the pin stopband (7) of reverse projection in the adjacent configuration between the pyramid groove (4) of leaning forward.
In the present embodiment,, also make the preceding elongation of pin (6) be enlarged to 110-150% in order to increase the metal inflow space.
The pyramid groove that leans forward, 25-30 ° of its groove two facade angle, symmetrically arranged pyramid groove floor angle by 38 °-41 ° to recess outlet gradual change to 43 °-46 °.Pin stopband (7) highly also is gradient to the 1.2mm of recess outlet along the conical surface by 1mm.
Utilize this mould can produce the multichannel aluminum alloy flat tube of wall thickness 0.5-0.7mm.
Claims (4)
1, a kind of aluminium alloy extruded die for processing, constitute by patrix that disposes tap hole, pin front end and counterdie with seam chamber, the pin front end narrow slit root side that it is characterized in that patrix, be symmetrical arranged the pyramid groove that leans forward, and dispose the pin stopband that is reverse projection between the pyramid groove in adjacent leaning forward.
2, according to the described aluminium alloy extruded die for processing of claim 1, it is characterized by the pyramid groove that leans forward, 25-30 ° of two facade angle, symmetrically arranged pyramid groove floor angle by 38-41 ° to the recess outlet gradual change to 43-46 °, pin stopband height also is gradient to the 1.2mm of recess outlet along the conical surface by 1mm;
3,, it is characterized in that tap hole and seam cavity length are extended to pin front end overall with 110-150% according to claim 1,2 described aluminium alloy extruded die for processing;
