Abstract
The utility model relates to a front-mounted spreading aluminium profile extrusion die, which is formed by a circular extrusion drum, a spreading die and a forming die. The spreading die is disposed between the forming die and the circular extrusion drum, the middle portion of a die cavity of the spreading die is 25-40% narrower than the left end and the right end of the die cavity, an expansion angle of 18-25 degrees is formed by an upper conical face and an axis of the die cavity, and a pressure-relief angle of 10-20 degrees is formed by a lower conical face and the axis of the die cavity. The extrusion die eliminates an extrusion flat drum, has fine spreading effect of ingot billets when extruding, improves profile quality, and has a structure capable of reducing extrusion force, prolonging service life and lowering manufacturing cost.
Description
Technical field
The utility model relates to a kind of extruding die for aluminum shaped material, especially a kind of preposition extruding die for aluminum shaped material that spreads.
Background technology
Because it is increasingly extensive that aluminium section bar is used, and effectively promoted the development of extrusion process and extrusion die.In recent years, spreading eka-aluminum row section bar is being used widely aspect conduction and the fin inserting type heat radiator.And it is most of higher to the surface and the dimensional requirement of section bar.China's present large-size extruder platform number is few, adds extruding cost height, so people often push super excellent section bar with little tonnage extruder.But because the mould deflector adopts the direct-push pan feeding more, extruding force is little, and the aluminium deformation time is short, and the flow of external aluminium is less, causes the mould outer for the aluminium deficiency, and mould is easy to generate the shake and the angle problem of collapsing.In order on the extruder of certain tonnage, to produce the qualified wide section bar of super extruding barrel dliameter, spread the mould extruding and develop, this is a kind of development to flat tube extruding.The replacing of this mould is easier than flat extruding cylinder, has higher production efficiency and economy, has received the concern of section bar manufacturer.But, need be used in combination owing to spread mould great majority with flat tube, exist the problem of trouble during the installation of this structure, bring to a certain degree inconvenience to the user.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned deficiency, and a kind of preposition extruding die for aluminum shaped material that spreads is provided, and it is good that it not only spreads performance, can replace flat tube extruding, and easy for installation, section quality good.
The purpose of this utility model is achieved in that by circular recipient, spreads the preposition extruding die for aluminum shaped material that spreads that mould, shaping mould are formed, and spreads mould and places before the shaping mould, and the middle part of its die cavity subtracts narrow 25%-40% than the left and right end of die cavity.
The described preposition extruding die for aluminum shaped material that spreads, its die cavity middle part extended corner that the upper and lower conical surface and axis constituted is 18-25 °.
The described preposition extruding die for aluminum shaped material that spreads, the release angle that the left and right two ends of its die cavity conical surface and axis are constituted is 10-20 °.
The beneficial effects of the utility model are to be prepended to before the shaping mould spreading mould, save the flat tube of extruding, and ingot blank spreads effectively during extruding, and section quality improves; This structure can reduce extruding force, prolongs die life, reduces production costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, die cavity left end; 2, die cavity middle part; 3, die cavity right-hand member; 4, the die cavity left end conical surface; 5, extended corner; 6, release angle; 7, subordinate's conical surface in the die cavity.
The specific embodiment
In Fig. 1-Fig. 2, by circular recipient, spread the preposition extruding die for aluminum shaped material that spreads that mould, shaping mould are formed, to spread mould and place before the shaping mould, its die cavity middle part (2) subtracts narrow 25%-40% than the left and right end of die cavity (1,3).The preposition left and right end conical surface of die cavity (4) that spreads extruding die for aluminum shaped material is 18-25 ° with the extended corner (5) that axis is constituted.The preposition die cavity upper and lower conical surface in middle part (7) that spreads extruding die for aluminum shaped material is 10-20 ° with the release angle (6) that axis is constituted.This structure is in extrusion process, and the ingot blank end flows into preposition when spreading the mould center, does not flow out shaping mould immediately, but, flow the centre of equilibrium and outside pressure according to the principle of resistance minimum to two ends, until being full of the whole preposition mould that spreads, reach the mould outer for the aluminium abundance.Under the effect of pressure, ingot blank is thinned preposition spreading in the mould, spread distortion, pass through extrusion molding behind the calibrating strap of shaping mould again.
Claims (3)
1. preposition extruding die for aluminum shaped material that spreads, by circular recipient, spread mould, shaping mould is formed, it is characterized in that: spread mould and place before the shaping mould, the middle part of its die cavity (2) subtract narrow 25%-40% than the left and right end of die cavity (1,3).
2. the preposition extruding die for aluminum shaped material that spreads according to claim 1 is characterized in that the extended corner (5) that the die cavity upper and lower conical surface in middle part (4) and axis are constituted is 18-25 °.
3. the preposition extruding die for aluminum shaped material that spreads according to claim 1 is characterized in that the release angle (6) that the left and right two ends of the die cavity conical surfaces (7) and axis are constituted is 10-20 °.
