Description
Technical field
It is specially a kind of for aluminium alloy extruded molding temperature control dress the invention belongs to aluminium alloy extruded processing technique field
It sets.
Background technique
Molded aluminium extruded is to apply powerful pressure to the metal stock being placed in mold cavity (or extrusion cylinder), forces gold
Category blank generates orientation plastic deformation, squeezes out from the die hole of extrusion die, to obtain required section configuration, size and have
The part of certain mechanical properties or the plastic processing method of semi-finished product.
Conventional Extrusion Process of Aluminum Alloy Profile method is divided into forward extrusion and reverse extrusion, and the difference of the two, which essentially consists in extrusion cylinder, is
It is no to be moved during extrusion process；The molding process characteristic of aluminium extrusion includes: in extrusion process, to be extruded metal and exist
Deformed area, which can be obtained, forges more strong and uniform three-dimensional compressing stress state than rolling, this can give full play to processed
The plasticity of metal itself；Extrusion forming can not only produce the simple stick of cross sectional shape, pipe, type, line product, can also produce and cut
The complex-shaped profile in face and tubing；Extrusion forming flexibility is big, it is only necessary to which the compression tools such as more mold exchange can be set at one
The standby upper production shape specification product different with kind, replaces the simple and efficient to handle, time saving, efficient of extrusion die；Squeeze system
The precision of product is high, and products surface quality is good, also improves the utilization rate and yield rate of metal material；Power of the extrusion process to metal
Learning performance has desirable influence；Process flow is short, convenient for production, and primary squeeze can or obtain than the side such as hot forging or formation rolling
The bigger integral structure component of method area, equipment investment is few, die cost is low, high financial profit；Aluminium alloy has good extruding
Characteristic can be processed particularly suitable for extrusion process by a variety of extrusion process and multiple kinds of molds structure.
Equally, there is also many disadvantages for aluminium extrusion processing technology: being primarily due to the flexibility of aluminium extrusion processing, needs pair
Require to be switched fast different fashion of extrusion in different extrusion process, and existing forward extrusion process equipment, only small part
Allow hand over as backward extrusion processing method, but this it is also only interim replace, can not process for a long time and under processing quality also has
Drop；And works as and forward extrusion process equipment is used temporarily to be switched to reversed pattern of pressure, the dismounting of complete equipment and part exchanging
Need many times, hence it is evident that affect processing efficiency；Secondly, forming panel indispensable in aluminium extrusion process,
Its replacement disassembly efficiency is also one ring of key for influencing processing efficiency；In view of life problems, template cannot use for a long time,
Similarly for different machine-shaping requirements, it is also desirable to debugging replacement template rapidly；Secondly, extrusion aluminum-type material bubble and peeling
Defect also often occurs, the reason is that being that extrusion cylinder or dummy block are too dirty, clast and waste residue therein are not cleared up in time
It goes out, and when replacement alloy, is not cleaned out in cylinder；When temperature in extrusion cylinder and too high extruding ingot casting temperature, also having can
Surface of profile bubble and peeling can occur.
For common forward extrusion, more friction can be occurred with the inner wall of extrusion cylinder by squeezing ingot casting, therefore will lead to
The Surface of profile burr and smoothness defect of forward extrusion output are more than reverse extrusion, and the key for being used to alleviate the defect exists
In the use of processing technology and lubricating oil, when for each replacement alloy pig, require to carry out it efficient and comprehensive
Upper lubricating oil operation.
