A kind of process improving density of injection molding high-speed steel columnar deposition blank, this method, which mainly passes through, reduces sedimentary to spray
Intensity is higher, plasticity is good and high-speed steel ingot blank with preferable processing performance to obtain for the height of mouth.The above method it is common
Feature is that blast atomizer is fixed, since injection drop stream sputters limited area, is encountered when preparing large scale blank tired
Difficulty, while the drop size being atomized is in generally Gaussian Profile along atomization vertebra, is an impediment to the uniformity of deposit preform tissue.Chinese patent
ZL01114421.1 provides a kind of mobile crucible jetting precipitation device, so that injection drop stream scans on deposit preform to solve
The limited problem of fixed atomizer injection drop stream depositional area, for preparing large scale blank.But since scanning speed is limited,
In relatively long distance scanning, sputtering interface, or even layering are easy to appear between single pass sedimentary.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the jet deposition mentioned in background technique preparation large scale high speed
Limitation in steel blank provides a kind of swing type spray deposition blank-making method, and accordingly provides a kind of equipment and simply swing
Formula atomizer.Interface bond strength is high between jet deposition large scale high-speed steel ingot blank sedimentary, the injection good in conjunction with situation
Deposition large scale high-speed steel ingot blank carbide particle is tiny and is uniformly distributed, the jet deposition large scale high-speed steel ingot blank crystal grain
Tiny, internal structure is on a small quantity or without gross segregation.
To achieve the goals above, the invention proposes a kind of swinging type atomizing devices of processing step simplicity and swing type to spray
Penetrate deposition blank-making method, the swinging type atomizing device includes: spray chamber, settling chamber and control system are set in the spray chamber
There are tundish device, support plate device, bellows pendulous device, the tundish device is made of casting ladle and tundish, described
Casting ladle bottom is connected by catheter with the tundish, the metal bath continuous uniform water conservancy diversion in the casting ladle is entered described
In tundish, the support plate device is made of support plate, cam, locating shaft, slide plate, below the support board ends with it is described
Cam is connected, and intermediate position is supported on the bellows in the bellows pendulous device, the bellows pendulous device by
Bellows and the atomizer being arranged in bellows composition, the top of the atomizer is fixed on the substrate in the following, in described
Between packet bottom be connected by catheter with the atomizer, by the tundish metal bath feeding atomizer, and
It is atomized in atomizer, the cam rotation drives the substrate both ends to swing around the bellows, is fixed on support to drive
Atomizer below plate is swung, and forms the pyrosol of swing；Substrate, substrate post and rot, institute are equipped in the settling chamber
The upper end that substrate is fixedly connected on the substrate post is stated, substrate lower end is connected on the rot, the rot
On the one hand it drives the substrate post to rotate, the substrate post is on the one hand driven to move up and down；The control system is by center
Controller, data collector, lifting controller, sled controller, digital display laser device composition, the central controller is by each data
The data of collector carry out processing and to lifting controller, sled controller publication instruction, control respectively the slide plate slides and
The substrate post moves up and down, and the collected information of digital display laser device is collected and is transferred to central control by the data collector
Device processed, the digital display laser device are used to acquire each set information of monitored component；
The catheter swing angle range between the tundish and the atomizer is 3~5 °；
Further, the cam is designed to drive the angle model of atomizer support plate, tundish and bellows needed for injection
The other machinery structure type swung is done in enclosing；
Preferably, attemperator is arranged in the casting ladle and tundish outer wall, when high-speed steel melt being made to flow through tundish or casting ladle at
Molten condition.
Wherein the swingable atomizer support plate device refers to: such rotatable means such as cam or shaft and biography
System jet deposition atomizer support plate combines, and under such rotatable means such as cam or shaft, drives atomizer support
Plate, tundish and bellows are swung in the angular range needed for injection.
In above-mentioned ladling apparatus and tundish device, attemperator can be set in casting ladle and tundish outer wall, make high-speed steel
Molten condition at when melt flows through tundish or casting ladle, prevents from making because temperature is too low that high speed steel melt solidifies or half solidification causes
Liquid pipe or nozzle blocking and hinder injection go on smoothly.
Above-mentioned ladling apparatus and tundish device, it is preferred that the high-speed steel melt spray leaching in course of injection, in tundish
Do not have top pours water-coating port, and to prevent in casting ladle swing process, the melt in casting ladle is not because tundish catheter sprays continually
Melt out and generate splashing.
As a general technical idea, the present invention also provides a kind of swing type spray deposition blank-making method, including it is following
Step:
(1) a kind of high speed steel material or intermediate alloy are selected, wherein the high speed steel material or intermediate alloy can be powdered or
It is blocky；
(2) step (1) high speed steel material or intermediate alloy are put into smelting furnace and are heated above alloy melting point, and molten
Furnace inside holding obtains ingredient and temperature is uniform to making melting high speed steel melt each section ingredient and temperature reach uniform state
High speed steel melt；
(3) the resulting ingredient of step (2) and the uniform high speed steel melt of temperature are poured into the casting ladle of preheating, casting ladle is placed in injection
Above tundish on plate；
(4) in step (3) from casting ladle flow out high-speed steel melt flow in preheated tundish in, high-speed steel melt outflow in
Between packet catheter moment, with high speed N2 stream the melt of outflow is crushed by catheter, and rotate go up lower cam, make atomizer
Support plate and tundish are with the rotation of cam and bellows swing, and broken high-speed steel drop stream is with atomizer oscillatory scanning
It sputters on the substrate rotated in settling chamber, the substrate rotated in course of injection constantly declines, to control the deposition constantly accumulated
The height of layer and tundish catheter remains unchanged, until injection is completed；
(5) the high-speed steel ingot blank prepared after to be sprayed is cooling, by the means such as forging or rolling that high-speed steel ingot blank is fine and close
Change processing.
In a kind of above-mentioned swing type spray deposition blank-making method, it is preferred that high speed steel material purity > 99% or intermediate alloy
Purity > 99%, and choose small blocky high speed steel material or intermediate alloy carries out melting, choose small block-like high speed steel material or in
Between the benefit of alloy melting be that the larger blocky high speed steel material of burn-off rate or intermediate alloy burn-off rate are fast and higher than powdered
Fast steel or intermediate alloy are at low cost.
In a kind of above-mentioned swing type spray deposition blank-making method, it is preferred that in smelting furnace, high-speed steel or intermediate alloy add
Heat is to its theoretical 100~250 DEG C, 30~180min of soaking time of fusing point is higher than, to keep high-speed steel bath composition and temperature equal
It is even.
In a kind of above-mentioned swing type spray deposition blank-making method, it is preferred that high speed steel melt is with the speed of 1.5~20kg/min
Degree pours into the casting ladle of preheating, and casting ladle nozzle diameter avoids making high speed steel melt because nozzle diameter is too small within the scope of 8~12mm
