Abstract

The utility model relates to an aluminium alloy production die and particularly discloses a special-shaped aluminium alloy seamless square tube extrusion die. The special-shaped aluminium alloy seamless square tube extrusion die comprises a die body and is characterized in that a needle point of an extrusion needle is inserted in the die body; the needle point is combined with the die body to form a cavity which is of a product shape; the extrusion needle is arranged in an extrusion cylinder and an extrusion rod is arranged at the tail end of the extrusion needle; an extrusion cushion is arranged at the front end of the extrusion rod; the extrusion cylinder is filled with an extrusion sheared billet. The aluminium alloy production die has a simple structure; a product is not provided with welding seams; the aluminium alloy production die has uniform and stable tissue performance, is not provided with cracks after being flared or flattened, and can be used as a bearing structural part and the like.

Description

A kind of aluminium alloy special-shaped seamless square tube extrusion die
(1) technical field
The utility model relates to a kind of aluminium alloy production mould, particularly a kind of aluminium alloy special-shaped seamless square tube extrusion die.
(2) background technology
Aluminium extrusion is the means of forming aluminium section.First according to section bar product Section Design, produce mould, utilize extruder by the casting rod heating extrusion molding from mould.During existing aluminium extrusion is produced, aluminum alloy square tube intelligence is produced with plane distribution composite die tool or bridge-type combination die, no matter adopt which kind of mode of production, there is weld seam in the square tube of extruding, end face structure property is inhomogeneous, easily produces fatigue crack, can not be for making pressure part and stressed member.
(3) summary of the invention
The utility model is in order to make up the deficiencies in the prior art, provide a kind of simple in structure, good product performance for pushing circumscribed circle diameter 400mm with interior aluminium alloy special-shaped seamless square tube extrusion die.
The utility model is achieved by the following technical solution:
A kind of aluminium alloy special-shaped seamless square tube extrusion die, comprise die body, it is characterized in that: the needle point that is inserted with squeezing needle in described die body, needle point and die body are combined to form the cavity of article shape, squeezing needle is arranged in recipient, and being provided with endways pressure ram, pressure ram front end is provided with dummy block, is loaded with extruded rod base in recipient.
The utility model is comprised of die body and needle point two parts.When extruding is produced, under the effect of extruding force, the metal in recipient flows out and forms special-shaped seamless square tube section from the gap of needle point and die body; The mobile power that provides that pressure ram is metal in recipient, dummy block plays corresponding cushioning effect, extruded rod base is realized the strong bonded of recipient and squeezing needle, meanwhile, the cavity mouth of article shape is played to the moulding that certain sealing function is convenient to realize square tube.
More excellent technical scheme of the present utility model is:
Four bights of described die body are provided with water conservancy diversion hole, guarantee metal Gongliu County, facilitate square tube corner-shaping.
For controlling section bar profile, guarantee that discharging is even, die sleeve work band value has been carried out strict calculating; Described needle point top is square, and bottom is circular, adopts taper seat transition between the two, has guaranteed that metal is more even for stream.
Situation about not waiting for square tube wall thickness, is provided with amount of bias on four sides of described needle point, be convenient to predeformation.
For guaranteeing assembly precision, prevent inclined to one side wall, on the cylindrical of described die body, be provided with alignment pin, for die sleeve precision-fit.
For convenience of assembling, prevent from, because assembling error appears in needle point rotation, on the end face of described needle point, being provided with direction signs.
The utility model is simple in structure, and product does not exist weld seam, and structure property is uniform and stable, and enlarging, flattening free from flaw, can be used as bearing structure part etc.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the main TV structure schematic diagram of die body;
Fig. 3 is the left TV structure schematic diagram of die body.
In figure, 1 pressure ram, 2 dummy blocks, 3 recipients, 4 squeezing needles, 5 extruded rod bases, 6 needle points, 7 die bodys, 8 goods.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises die body 7, in described die body 7, be inserted with the needle point 6 of squeezing needle 4, needle point 6 and die body 7 are combined to form the cavity of goods 8 shapes, squeezing needle 4 is arranged in recipient 3, and be provided with endways pressure ram 1, pressure ram 1 front end is provided with dummy block 2, is loaded with extruded rod base 5 in recipient 3; Four bights of described die body 7 are provided with water conservancy diversion hole; Described needle point 6 tops are square, and bottom is circular, adopts taper seat transition between the two; On four sides of described needle point 6, be provided with amount of bias; On the cylindrical of described die body 7, be provided with alignment pin; On the end face of described needle point 6, be provided with direction signs.
The utility model adopts die body 7 and needle point 6 two-part structure in order to push special-shaped aluminium alloy seamless square tube; Die body 7 arranges distinguishing water conservancy diversion hole, guarantees that metal is for stream everywhere; Needle point 6 square shaped top and rounded bottom adopt taper seat rounding off, have guaranteed that metal is more even for stream.When extruding is produced, under the effect of extruding force, the metal in recipient 3 flows out and forms special-shaped seamless square tube section from the gap of needle point 6 and die body 7.
