Description
Technical field
The present invention relates to aluminum profile preparation technical fields, more particularly to a kind of equal calibrating straps extrusion die.
Background technique
Traditional extruding die for aluminum shaped material, because aluminum profile cross section is typically more complicated, it is necessary to different by design height
Calibrating strap control the flow velocity of profile section different piece, to obtain stable aluminium extrusion product (figure one), calibrating strap is not
Be generally 3~10mm high with height causes squeeze pressure big since longer calibrating strap will generate a large amount of frictional heat, squeezes
It presses speed slow, causes production efficiency low, aluminum profile expression surface quality is unstable；The processing of the calibrating strap of conventional extrusion dies simultaneously
Copper electrode accurate by production first is needed, calibrating strap out is corroded by electric discharge, processing efficiency is slow.
Summary of the invention
In order to solve the problems, such as above-mentioned background technique, the present invention provides a kind of equal calibrating straps extrusion dies, this waits calibrating straps
Extrusion die lower die waits calibrating straps using height is consistent, and an offset outward is arranged in its outer periphery of lateral edge on equal calibrating straps
Flow control chamber, and the flow control chamber different parts side wall is inconsistent to the distance between equal calibrating straps, makes aluminium bar in stream
The flow velocity of aluminum profile cross section different parts is unequal in fast control chamber, to obtain the stable aluminium extruded section of quality.
To achieve the above object, the invention provides the following technical scheme:
A kind of equal calibrating straps extrusion die, including upper die and lower die, the upper mold include upper die body, aluminium bar spout, upper die head,
The aluminium bar spout is set among upper die body, set altogether there are four, and the arrangement that is centrosymmetric, four aluminium bar spouts two-by-two it
Between be equipped with entity muscle, the upper die head is set to entity muscle end face center position, and the lower die includes lower mold body, calibrating strap, institute
After stating upper mold and lower die molding, upper die head and calibrating strap form extrusion pressing type chamber, the extruding cavity shape, size and aluminum profile shape
Shape, size match, it is characterised in that the calibrating strap is set as equal calibrating straps, this waits the height of calibrating straps consistent, the lower die
Body is equipped with the flow control chamber deviated outward in the calibrating straps outer periphery such as lateral edge on equal calibrating straps, and the flow control chamber side wall arrives
The unequal apart from size of calibrating straps outer periphery is waited, flow velocity of the distance with aluminium bar in profile section different parts matches.
Further, the equal calibrating straps height is set as 2~3mm.Equal calibrating straps height shortens 60% compared with traditional moulds, squeezes
Frictional force is small when pressure, and extrusion speed is fast, high-efficient.Extrusion speed is compared with 25% or more traditional moulds speed-raising.
Further, the flow control chamber height is set as 5~8mm.
Further, the flow control chamber is equipped in the entity muscle direction four corners of upper mold and upper mold after lower die molding
First arc groove balances influence of the entity muscle to flow velocity for improving the aluminium bar flow velocity of the four corners.
Further, the flow control chamber is equipped at rectangular recess in aluminum profile and is equipped with the second arc groove.For mentioning
High aluminum profile is equipped with the aluminium bar flow velocity at rectangular recess, balances influence of the rectangular recess to flow velocity.
Further, the flow control chamber is equipped with third arc groove in aluminum profile corner.For improving aluminum profile
The aluminium bar flow velocity of corner balances influence of the turning to flow velocity.
Further, the upper die body height reduces 20~25% with money extruding die for aluminum shaped material upper die body height than tradition.
Reduce die steel consumption.
Further, the aluminium bar spout volumetric ratio tradition of the upper mold is the same as money extruding die for aluminum shaped material upper mold aluminium bar feeding
Mouth volume enlargement 45~55%.Therefore squeeze pressure is small, small compared with traditional moulds by 30% or more, low energy consumption for extruding.
Compared with prior art, the invention has the benefit that 1, no longer need to calculate the different height of calibrating strap, pass through
The flow control chamber for increasing by 5~8mm height controls setting for different parts speed by mold calibrating strap instead of tradition
Meter；2, it no longer needs additionally to make copper electrode and removes processing calibrating strap, it is only necessary to is unified when processing profile outlet by machining center
It processes；3, aluminium bar spout is big, increases 45~55% compared with traditional moulds aluminium bar spout, therefore squeeze pressure is small, compared with
Traditional moulds are small by 30% or more, and low energy consumption for extruding；4, calibrating strap height shortens 60% compared with traditional moulds, and frictional force is small when extruding, squeezes
Press speed fast, high-efficient, extrusion speed is compared with 25% or more traditional moulds speed-raising；5, upper mold height contracts compared with traditional moulds upper mold height
Short by 20~25%, die steel consumption is low, saves 20% or more die steel compared with traditional moulds.
