Abstract
The invention relates to a front-mounted broadened aluminum profile extruding die. The front-mounted broadened aluminum profile extruding die comprises a round extruding cylinder, a broadening die and a forming die, wherein the broadening die is arranged between the forming die and the round extruding cylinder, and the middle part of a die cavity of the broadening die is narrower than the left and right end parts of the die cavity by 25-40%; an extending angle formed by an upper conical surface of the die cavity and the axis is 18-25 degrees; a pressure relief angle formed by a lower conical surface of the die cavity and the axis is 10-20 degrees. According to the front-mounted broadened aluminum profile extruding die, a flat extruding cylinder is saved, the broadening effect of an ingot blank is good during the extruding, and the quality of a profile is improved; by utilizing the structure, the extrusion force can be reduced, the service life of the die can be prolonged, and the production cost can be lowered.
Description
Technical field
The present invention relates to a kind of extruding die for aluminum shaped material, especially a kind of preposition spreading aluminium profile extrusion die.
Background technology
Increasingly extensive due to aluminium section bar application, 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 fin inserting type heat radiator.And most of higher to surface and the dimensional requirement of section bar.The current large-size extruder number of units of China is few, adds the extruding cost high, 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, the aluminium deformation time is short, and the flow of external aluminium is less, causes the mould outer for the aluminium deficiency, and mould easily produces shake and the angle problem of collapsing.In order on the extruder at 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 cylinder 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, owing to spreading the mould great majority, need be combined with flat cylinder, exist the problem of trouble during the installation of this structure, bring inconvenience to a certain degree to the user.I company have declared utility model patent in September, 2009 this project, and the patent No. is 200920094440.2.
Summary of the invention
The objective of the invention is to be to overcome above-mentioned deficiency, a kind of preposition spreading aluminium profile extrusion die is provided, it is good that it not only spreads performance, can replace flat cylinder extruding, and easy for installation, section quality good.
The object of the present invention is achieved like this: by circular recipient, spread the preposition spreading aluminium profile extrusion die that mould, shaping mould form, spread before mould is placed in shaping mould, the middle part of its die cavity subtracts narrow 25%-40% than the left and right end of die cavity.
Described preposition spreading aluminium profile extrusion die, the extended corner that its die cavity upper and lower conical surface in middle part and axis form is 18-25 °.
Described preposition spreading aluminium profile extrusion die, the release angle that its die cavity left and right two ends conical surface and axis form is 10-20 °.
Before the invention has the beneficial effects as follows that will spread mould is prepended to shaping mould, save the flat cylinder of extruding, during extruding, ingot blank spreads effectively, and section quality improves; This structure can reduce extruding force, extends die life, reduces production costs.
The accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the present invention is further described
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
In 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 die cavity.
the specific embodiment
In Fig. 1-Fig. 2, by circular recipient, spread the preposition spreading aluminium profile extrusion die that mould, shaping mould form, to spread before mould is placed in shaping mould, its die cavity middle part (2) subtracts narrow 25%-40% than the left and right end of die cavity (1,3).The left and right end conical surface of the die cavity of preposition spreading aluminium profile extrusion die (4) is 18-25 ° with the extended corner (5) that axis forms.The preposition spreading aluminium profile extrusion die die cavity upper and lower conical surface in middle part (7) is 10-20 ° with the release angle (6) that axis forms.This structure is in extrusion process, and the ingot blank end flows into preposition while spreading the mould center, does not flow out immediately shaping mould, but, according to the principle of resistance minimum, to two ends, flow, the centre of equilibrium and outside pressure, until be 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 in spreading mould preposition, width spread occurs, then extrusion molding after the calibrating strap of shaping mould.
Claims (3)
1. a preposition spreading aluminium profile extrusion die, by circular recipient, spread mould, shaping mould forms, it is characterized in that: spread before mould is placed in 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. preposition spreading aluminium profile extrusion die 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 form is 18-25 °.
3. preposition spreading aluminium profile extrusion die 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 form is 10-20 °.
