Technical field
The invention belongs to extrusion technique field, more particularly to a kind of detachable combination extrusion die.
Background technology
Extrusion axis is the core component in extrusion process, and its fatigue life, economy and structural compactness have very high
It is required that.Traditional extrusion axis mainly uses monolithic construction, and it has the advantages that to be simple to manufacture.Extruded using traditional monoblock type
Axle extrusion process is as shown in figure 1, its mould includes 4 parts altogether：Extrusion die (3), recipient (2), plug (7) and extrusion axis
(1).The basic process of extruding：Recipient is displaced downwardly into extrusion axis to be passed from recipient top, the dynamic beam of extrusion die and press is consolidated
It is fixed；The blank that would be heated to predetermined temperature is placed on the upper surface of extrusion axis；To be moved on recipient and with have been fixed on dynamic beam
Extrusion die locking；Recipient moves down extrusion billet and completes crush stroke with extrusion die in the case where dynamic sill bolt is dynamic；Recipient and extruding
Mould moves in dynamic sill bolt and is moved on lower and take out extruding steel pipe；Recipient moves down the extruding for starting next workpiece.
Extrusion axis is needed to be engaged to complete extrusion process with recipient in actual use.In extrusion process, blank becomes
Shape amount large deformation drag is high, is typically necessary extruding force higher therefore for the gap length between extrusion axis and recipient
Control requires very high.Blank can be stuck between extrusion axis and recipient and cause crowded if the gap of extrusion axis and recipient is excessive
Hypertonia, and the extrusion axis that weares and teares even makes extrusion process to carry out with recipient；If the gap of extrusion axis and recipient
It is too small, then because the squeezing action that recipient loses blank can produce certain resilience to make extruding after crush stroke terminates
Cylinder internal diameter diminishes, therefore extrusion axis easily occurs stuck phenomenon with recipient in backhaul is extruded, and makes what extrusion process was interrupted
It is also easy to make recipient and extrusion axis premature failure simultaneously.In addition, extrusion axis stressing conditions in extrusion process are more severe,
Easily with blank or recipient friction, therefore its rate of wear is very fast for the edge of extrusion axis, if extrusion axis is carried out into integral replacing
Then high cost, and often Renewal process needs the more time also to influence production efficiency.
It can thus be appreciated that extrusion axis has two big shortcomings using monolithic construction：1st, when recipient in extrusion process and extrusion axis
Between produce extruding reflux flash after, extrusion axis can be produced to recipient inwall and scratch and reduce longevity of recipient during extruding backhaul
