Description
Technical field
The utility model is related to hot-working field, specifically a kind of to be squeezed by controlling metal flow one-shot forming in tap hole
Go out the mould of various dimensions elbow member.
Background technology
Because bent pipe parts readily satisfy the requirement to aspects such as product lightweight, high intensity and low consumption, in aviation and
It is widely applied in the high-tech sectors such as space flight, in addition to the transfer pipeline of gas, liquid is widely used in, is also widely used as
Hardware.With the development of the high-tech sectors such as aerospace, to demand increasingly thin-walled property, the processing one of bend pipe
Change, traditional elbow member processing mainly there are two methods, and one kind is to push away curved, also makes extruding bend, and also one kind is to go for a stroll.No matter
It is above-mentioned which kind of method, is required to two complete equipments, i.e.,（1）Metal stock is made the equipment of straight pipe, can be drawing, be squeezed
The equipment such as pressure, rolling；（2）Straight tube is gone for a stroll or curved machine is pushed away, generally around bender and pushing away bender.
A kind of extruding die for bent pipe is disclosed in the utility model of Publication No. CN203389973U is created, it specifically does
Method is that straight tube is placed in groove first, then drives extruding guide wheel to push by driving hydraulic cylinder, thus can directly
Pipe becomes bend pipe.It is so easy to use, efficiency high, but, its raw material is the straight tube for having been processed into shape.Needing early stage is carried out
Solid blank is processed into straight tube.
Metal winding pipe device is disclosed in the utility model of Publication No. CN204583951U is created, by extruding control
The arc of the end face of collective effect and bend pipe the extruding pushing block of cylinder and heater is set, and completes to make the bending of metal straight pipe
Industry.Likewise, being characterized in carrying out pushing away curved operation, only power mode with foregoing utility model not on the basis of existing straight tube
Together.
A kind of aluminium alloy pipe bending forming side is disclosed in the utility model of Publication No. CN103861912A is created
Method；Its way is that the alloying metal fritter of low melting point is put into the straight tube for needing to bend, and then makes slug by heating
Fusing, is being gone for a stroll after cooled and solidified on bender, is finally again flowed out filling metal molten automatically by heating.It is solved
Section occurs Severe distortion after aluminium alloy pipe bending forming, such as depression, projection problem.But it is characterized in using finished product
Straight tube, therefore also metal solid blank first must be processed into straight tube.
A kind of bending extruding of Even thickness elbow is disclosed in the utility model of Publication No. CN203389973U is created
Manufacturing process；It is put into mould after solid cylinder base is heated；Solid cylinder base is applied by drift compress axially, send out it
Raw perforation and plastic deformation；Mould is removed, equal diameter plug is removed, Even thickness elbow is obtained.The grade wall thickness for arriving of this method
Bend pipe has the disadvantage that：（1）Make extrusion bend pipe length low because the device for having stationary core rod stops, it is impossible to meet common use bar
Part；（2）Cannot realize that various dimensions bend pipe is produced, it can only carry out extruding bending in approximately the same plane；（3）After the completion of extruding,
Even thickness elbow is firmly stuck on plug, it is more difficult to removed, or tube wall is scratched in removal process.
In sum, currently without one kind from solid metallic blank to the integrally formed method of various dimensions elbow member；Additionally,
In shunting soldering extruding tubing, often cause the straight tube material of extrusion that there is certain bending because of the diameter error of tap hole
Degree, production and designer avoid this defect by every possible means, but have no and for this defect to use extruding bend pipe.
In view of this, the utility model provides a kind of by metal in tap hole in dynamic adjustment conventional shunt extrusion die
The mould and application method of flow, realize the wall thickness high accuracy high intensity fine grain elbow member such as production of machinery, not only thoroughly put
It is de- first to produce straight tube with traditional extruder, drawbench or roll mill straight tube is gone for a stroll or push away curved processing method, Er Qie again
Can be realized in process without the defect such as depression, projection, fold etc. the thick processing of wall elbow member.
