Abstract
The invention discloses an extrusion rod and application of the extrusion rod to a sunflower heat dissipater profile, and relates to a method for producing sunflower heat dissipater profiles. A pressing head is in threaded connection with the open end of a barrel-shaped main body of the extrusion rod; a spring is arranged in the barrel-shaped main body; a through hole coaxial with the spring is formed in the pressing head; an inner supporting rod is inserted into the through hole in a clearance manner; the front end of the inner supporting rod is fixedly connected with a rod head; and the rod head is arranged in the barrel-shaped main body in a clearance manner. Before the extrusion starts, the inner supporting rod extends into a tubular blank, and the rod head realizes a supporting function, so that a metal material can be prevented from flowing to the axis during the extrusion. According to the extrusion rod, tubular metal is taken as an extrusion molding blank, so that a metal material can be more reasonably distributed, the flowing speed at a profile outlet is more uniform, metal dead regions are greatly reduced in the extrusion process, the extrusion force is reduced, the burden on power equipment is alleviated, the energy consumption is also reduced, and the service life of a die is prolonged.
Description
Technical field
The invention belongs to shape extrusion field, particularly a kind of method adopting tubular blank to produce heronsbill shaped material of radiator.
Background technology
Being applied in of radiator is current more and more wider, involved by having in a lot of field.
Shaped material of radiator much all adopts hot extrusion to produce, and is use solid blank in production process mostly.But it is larger for some external diameters in actual production process, radiation tooth higher heronsbill radiator production difficulty still comparatively large, main cause is: hold before a mold during extruding there is serious dead band phenomenon, metal charge flow difficulties, feed is unbalanced, extruding force is comparatively large, die life is short.Have no the report adopting tubular blank to produce heronsbill shaped material of radiator at present.
Summary of the invention
The first object of the present invention proposes a kind of extrusion molding pressure ram for adopting tubular blank to produce heronsbill shaped material of radiator.
The present invention includes one end is the tubular body being provided with openend, be threaded in the openend of described tubular body a pressure head, in described tubular body, spring is set, described pressure head is offered through hole homoaxial with described spring, at the interspersed inner bracing piece of described through hole internal clearance formula, the front end fixed connecting rod head of inner bracing piece, described bar head clearance-type is arranged in tubular body.
Before extruding starts, along with inner bracing piece takes the lead in stretching in tubular blank, bar head is played a supporting role, and flows to axle center place to prevent metal charge in extrusion process.Along with the carrying out of extruding, the pressure head of pressure ram front end applies pressure to it after touching blank, along direction of extrusion flow forward under the condition of three-dimensional compressive stress, owing to have employed tubular blank, in extrusion process, blank minimizing corresponding to the contact area of mould, decreases the formation in dead band, greatly reduce extruding force, alleviate the burden of power-equipment, reduce energy consumption, the burden alleviating mould improves the life-span of mould.Simultaneously because the metal in blank bosom expects that the distance at the most edge of radiator decreases, can well reduce the current difference of metal, make feed balanced, flow velocity is tending towards even, well improves the mobile performance of metal.
In addition, the external diameter of described inner bracing piece rear end is in the tapering transition face reduced gradually.Make it can be separated with defective material well after extruding completes, be convenient to follow-up production.
Another object of the present invention proposes the application process of above pressure ram at heronsbill shaped material of radiator.
The blank being heated to 480 DEG C being placed on temperature is in the recipient of 450 DEG C, pressure ram integral forward lead, before extruding does not start, along with pressure ram reach, the inner bracing piece of pressure ram first stretches into the inner chamber of tubular metal, until the front end in contact of inner bracing piece is at the upper surface of mould, when pressure ram continues reach, the pressure head part of pressure ram and tubular blank end contact, along with pressure ram continues reach, tubular metal is clamp-oned the section bar of temperature needed for the in-mold molding of 460 DEG C with the extrusion speed of 3 ~ 6 ㎜/s by the tubular body of pressure ram and pressure head.
The present invention is extruded blank owing to have employed tubular metal, metal charge is distributed more reasonable, the flow velocity in section bar exit is more even, in extrusion process, metal dead band is reduced greatly, reduce extruding force, alleviate the burden of power-equipment, also reduce energy consumption simultaneously, improve the mold use life-span.The present invention is suitable for producing heavy in section section bar.

Detailed description of the invention
One, the structure of pressure ram:
As shown in Figure 1, the present invention includes one end is the tubular body 1 being provided with openend, spring 3 is set in tubular body 1, be threaded in the openend of tubular body 1 pressure head 2, pressure head 2 is offered the homoaxial through hole 4 with spring 3, at the interspersed inner bracing piece 5 of through hole 4 internal clearance formula, the front end fixed connecting rod head 6 of inner bracing piece 5, this bar head 6 clearance-type is arranged in tubular body 1, and the external diameter of inner bracing piece 5 rear end is in the tapering transition face 7 reduced gradually.
Two, processing technology:
For 6063 aluminium alloys, the heronsbill radiator that the present invention produces as shown in Figure 2.
To 6063 aluminium alloy tubular blank Homogenization Treatments before extruding, treatment temperature is 560 DEG C/6h, makes materials microstructure structure more even after process.
Adopt power frequency heating furnace by blank heating to 480 DEG C, by mould and die preheating to 460 DEG C, the temperature of recipient is set in 450 DEG C, and the blank temperature controlling mould outlet place is greater than 500 DEG C.
As shown in Figure 3, the blank being heated to 480 DEG C being placed on temperature is in the recipient of 450 DEG C, by the center of the back-end aligned tubular blank 11 of the inner bracing piece 5 of pressure ram, and to adjust extrusion speed be 3 ~ 6 ㎜/s, be that the tubular blank of 480 DEG C is clamp-oned in mould by temperature, then obtaining continuous cross-section in the outlet of mould is the fansink-type material shown in Fig. 2.
From Fig. 4,5, before extruding does not start, along with the reach of pressure ram, inner bracing piece 5 rate is introduced into the effect that tubular blank plays support and fixing blank 11, until the front end in contact of inner bracing piece is at the upper surface of patrix 8, when pressure ram continues reach, pressure head 2 front end of pressure ram and the end contact of tubular blank 11, along with pressure ram continues reach, it is in the mould of 460 DEG C that blank 11 is clamp-oned temperature with the extrusion speed of 3 ~ 6 ㎜/s by tubular body 1 and pressure head 2, and meanwhile spring 3 shrinks.Under the constraint of recipient and inner bracing piece, metal, along direction of extrusion flow forward, flows through the product needed for mould aftershaping.
After extruding completes, pressure ram retreats, under the effect of spring 3, inner bracing piece 5 first keeps original position, and then inner bracing piece 5 reset boss and top cone angle effect under conveniently can realize the disengaging with defective material 12, to carry out follow-up regenerative ratio.
Extrudate adopts air-cooled online, carries out tension straingtening afterwards, and sawing shaping is packed.
