Detailed description of the invention
Fig. 1 aluminum alloy heat extrusion die planar structure schematic diagram in the prior art；
Fig. 2 is the aluminum alloy heat extrusion die planar structure schematic diagram that band of the embodiment of the present invention hinders angle.
Specific embodiment
As shown, a kind of band hinders the aluminum alloy heat extrusion die at angle, including die sleeve 3, die face is fitted in die sleeve 3
1 and die-cushion 2, successively it is fitted with supporting pad 9 and retainer platform 10 outside die sleeve 3, die face 1, die-cushion 2 are arranged in the middle part of supporting pad 9
The extrusion chamber for thering is front and back to penetrate through；1 extrusion chamber leading portion of die face is the water conservancy diversion hole 5 being relatively large in diameter, and back segment is the empty knife-band 7 that discharges, water conservancy diversion
Hole 5 and the empty knife 7 that discharges are work belt 6 between；The point diameter that work belt 6 is connect with water conservancy diversion hole 5 is greater than and the empty knife-band 7 that discharges
The rear end diameter of connection, so that 6 inner surface of work belt, which is constituted, has bevelled taper, it is empty that 6 point diameter of work belt is greater than discharging
7 diameter of knife-band, 6 rear end diameter of work belt are less than 7 diameter of empty knife-band that discharges；It is interior for having bevelled 6 inner surface of taper work band
The conical surface, inner conical surface and section bar extrusion direction form certain obstruction angle, and aluminum alloy materials 4 are suffered when by work belt
Frictional force due to inner conical surface inhibition and increase, aluminum alloy materials 4 are increased by the time of the flowing of work belt 6, in work
Make to form sufficiently large pressure between band, the filling of aluminum alloy materials and mouldability are significantly enhanced, while the surface matter of product
Amount and mobility improve, and corresponding production efficiency and die life have obtained different degrees of raising；6 rear end of work belt with go out
Expect that there is linear transition to form band 61 between empty knife-band 7, it is consistent with 6 rear end diameter of work belt that transition forms 61 diameter of band；Aluminium
Alloy material 4 forms the shape of product that 61 extrusion forming of band is design requirement by transition after work belt 6 hinders pressurization, is detached from
Transition molding 61 after-hardening of band is formed and passes through the empty knife 7 of discharging and discharges into subsequent extrusion chamber to retainer platform.
Supporting pad 9 includes front support pad, rear support pad, and extrusion chamber is respectively front support in the middle part of front support pad, rear support pad
Chamber 91, rear support chamber 92,2 middle part extrusion chamber of die-cushion are discharge hole 8, and front support chamber 91, rear support chamber 92, discharge hole 8, discharging are empty
Relationship is 92 91 diameter > discharge hole of diameter > front support chamber of rear support chamber, 8 diameter > discharging, 7 diameter of empty knife-band between knife-band 7；
10 upper surface of retainer platform and empty 7 minimum point of knife-band that discharges are located in same level；Each section of extrusion chamber that diameter is sequentially increased makes
Alloy product after extrusion forming gradually cooling, convenient for discharging.
The range of bevel angles of 6 inner surface of work belt is 35 °~45 °, hinders frictional force increasing for aluminum alloy materials
Simultaneously, it is ensured that the mobility of aluminum alloy materials；It is 40 ° that this example, which selects the bevel angle of 6 inner surface of work belt, and aluminum alloy materials increase
Add and frictional force and mobility is hindered to reach best cut point.
Work belt 6 and transition form tape spool to the empty knife-band axial length of the sum of length < water conservancy diversion hole axial length L T.LT.LT discharging；
Transition forms 1/3 that 61 axial length of band is 6 axial length of work belt, so that aluminum alloy materials obtain enough obstruction pressure,
Molding is reliable, it is ensured that product surface quality.
Band of the present invention hinders the aluminum alloy heat extrusion die at angle, and work belt and section bar extrusion direction with inner conical surface form one
Surely angle is hindered, so that the frictional resistance increase that aluminum alloy materials are suffered when by work belt, aluminum alloy materials pass through work
Time with flowing increases, and increases pressure of the aluminum alloy materials in work belt, enhances aluminum alloy materials filling and molding
Performance prevents product size variation from causing to deform, can be improved material flowability energy and product surface quality, extends mold and uses
Service life reduces production cost, improves production efficiency.
Concrete operating principle: by die face 1, die-cushion 2, die sleeve 3, water conservancy diversion hole 5, work belt 6, die face discharge empty knife 7,
The part such as die-cushion discharge hole 8 forms；The die face 1 of mold is fixed together with die-cushion 2 by screw thread and pin, and an entirety is formed
Structure come using.Inside the die sleeve 3 that set of molds is encased in fixed support mode after getting togather when producing extruding, put it to crowded
Then start to squeeze production above press.Aluminium alloy 4 is first contacted from die nose with die face, and aluminium alloy then flows into water conservancy diversion hole 5
The inside, flows into work belt 6 after forming sufficiently large pressure inside water conservancy diversion hole 5 again, and it is desired that product is formed inside work belt 6
It is flowed out again after shape, product has slightly cooled down and reached the portion of the empty knife 7 of die face discharging at this time after disengaging work belt 6
Point, product hardened sizing.Continue to squeeze forward after die-cushion discharge hole 8 by entering after die face sky knife followed by product
Pressure, then reached above the sliding retainer platform 10 before extruder by the supporting pad 9 of equipment, such a complete extruding
Process just finishes.
With traditional design difference: the not traditional flat construction of the mold work band part, with section bar extrusion side
To certain obstruction angle is formed, such aluminium alloy frictional force suffered when by work belt just be will increase, and aluminium alloy is logical
The time for crossing work belt flowing increases, and sufficiently large pressure is formed between work belt, the filling of such product and mouldability are big
The earth enhances, while the surface quality of product and mobility improve, and corresponding production efficiency and die life have obtained not
With the raising of degree.Purpose of design is can to effectively reduce product size variation in order to improve extrusion speed and improve product table
Face quality, while can also be improved the service life of mold, reduce enterprise's production cost and improving the purpose of production efficiency.
Work belt of the present invention hinders the structure at angle to have the advantage that
The speed of extruding can effectively be improved；
It can effectively guarantee change in size and surface quality；
3. can effectively improve production efficiency, production cost is reduced；
4. can effectively improve the service life of mold.
Inventive die and traditional moulds are that the carrying by mould steel as periphery is situated between in terms of extrusion forming technology
Matter squeezes out qualified product after carrying out shaping by the work band part of mould inside to aluminium alloy, connect to reach realization
The continuous purpose for squeezing production.
It can effectively improve the service life of mold.
