Description
Technical field
The utility model is related to forge processing technique field, and in particular to a kind of aluminum alloy forged combination backward extrusion bar dress
It sets.
Background technology
Aluminium alloy pipe backward extrusion has the characteristics that save material input, production efficiency height, the follow-up amount of machining of reduction,
Since aluminium alloy belongs to precious metal, save raw material input has very important realistic meaning in actual production,
Small lot production is carried out on forging press has many advantages, such as that with short production cycle, easy to operate, mold is simple, at low cost.
For the major-diameter thick-wall tubing of aluminium alloy diameter ＞ φ 350, length ＞ 1500, usually adopted on large-size extruder
It is produced with extrusion, with the continuous development of China's equipment manufacture, the use of major-diameter thick-wall tubing is presented to be increased year by year
The major-diameter thick-wall tubing of trend, especially high intensity is generally used for doing primary structure member use in various kinds of equipment.Due to high intensity
Larger extruding force is needed when tube extrusion, this just needs large tonnage extruder to realize, but large-size extruder is uncomfortable
It is produced for scattered small lot.It, must if still extruder is used to produce for the small and scattered big specification thick-walled pipe of this order
So haves the shortcomings that of high cost, production cycle length.Disadvantage one：I.e. tonnage is big greatly for the extruder appts ability needed；Disadvantage two：It throws
Enter big, extrusion cylinder and die cost is high；Disadvantage three：The preheating time of extrusion cylinder and squeezing needle is long when format change, general 2 days-
7 days；When producing the tubing of small lot major diameter, there is also production efficiency is not high and the shortcomings of cost is higher.
So feature more dispersed for this alloy and specification, that Batch orders are small, using backward extrusion on forging press
Method can preferably solve problem above.But the head room and impulse stroke of free forging press are limited, upper molds
The pipe length then produced according to the mode of monolithic extruded bar is limited, because to fully consider lower die and punch rod (upper mold)
Assembly height, closed height subtracts effectively minimum assembly height, and the pipe length that being only smoothly to take out (is usually less than
1300mm).Here, the head room of free forging press refers to the maximum distance between the moved cross beam of forging press and pedestal.
In the case of not taking certain moduli lamps structure, it is unable to the longer tubing of production length, that is, cannot be satisfied actual production institute
It needs.
