Description
Technical field
The invention belongs to 3D printings to manufacture new technical field, and in particular to one kind based on ultrasonic welding increase material and electric spark at
The 3D printing method of shape is a kind of compound 3D printing of component ultrasonic welding increasing material and electrical discharge machining of the inside with 3D cavities
Method.
Background technology
Due to 3D printing manufacturing technology can the complexity/super complex structural member that cannot achieve of monolithic molding those conventional methods,
With short production cycle etc. in addition without preparing mold, 3D printing manufacturing technology has vast potential for future development, is manufacturing industry in recent years
The hot spot of technology development.
Although this kind of increasing material manufacturing can make 3D component global formations, there are also problems, such as shape, size and precision
Difficulty reaches component requirement, and inner hollow and overhanging portion need disagreeable physical support etc..
The country cannot still solve these problems very well at present, and ultrasound increasing material is ground with EDM (electrical discharge machining) Integrated manufactures
Study carefully and have not been reported both at home and abroad, Abroad in Recent Years develops layering ultrasonic welding increasing material and attempts to disappear with the mode that NC millings are combined
Except these problems.Such as Solidica companies of the U.S.；For another example U.S. Fabfication companies.But this combination is generally all applied
Larger-size component processes occasion.Due to being difficult to eliminate cutter fillet, process system vibration and too big etc. bands of tool dimension
Next influence, layering ultrasonic welding increasing material are combined this pattern with NC millings and are still difficult to apply in inside with small in high precision
The component of 3D cavities, also 3D cavities top layer " ceiling " can not milling.
For example, being widely used on the heterodyne type array acceptor in the fields such as astrophysics, Atmospheric Survey, safety detection
Waveguide pole is exactly the internal typical primary structural component with the micro- 3D cavities (groove) of high-precision.With the development of science and technology, wave
Guide hole size requires smaller and smaller, higher and higher (size of the waveguide aperture along wave guide direction vertical cross-section rectangular cross section of required precision
It is required that reaching 0.508 × 0.254mm ranks or even 0.254 × 0.127mm；Receive the coupling part of telltale hole and reference signal hole
Size is divided to require smaller；And error will be within 10 μm, and surface roughness is within Ra0.4 μm).Due to tool dimension and knife
Has radius reason, the high-precision 3D network micro holes of this complexity are difficult to NC millings；Again due to vibration cutting, even if
It is layered welding using ultrasound and increases material and be combined manufacturing process with NC millings and still reaches to less than waveguide aperture in precision, fairness, uniform
The requirement of property, reliability and sharp comer etc.；Horizontally disposed reference signal duct top surface moreover " ceiling " layer can not milling
It cuts.Po, which is essential, to have new breakthrough in waveguide aperture component forming method.
The outstanding advantages that ultrasonic welding increases material are that pressure is small, and temperature is not high, affixed jail, and welding is uniform.It is welded according to thin slice
It connects, to the formed some effects of component with regard to smaller；If moreover whole welding of layering, there is hollow and hanging part that need not also prop up
It holds；Along with electrical discharge machining outstanding advantage is can to break through size forbidden zone, electrode size can be done smaller, and electric machining is vibrated
It is small, precision height etc..And these are exactly that small 3D pocket machinings are required, especially size reduces and surface smoothing is guaranteed.
Another outstanding advantage of electrical discharge machining is to form wedge angle, and the certain positions of some 3D component insides need to keep point
Reception telltale hole and reference signal hole on angle, such as waveguide primary structural component and the coupling aperture between them are spatial network cloth
It sets, but their section is rectangle, it is desirable that keep acute angle, the advantage of this exactly electric machining.And milling cutter radius can form fillet,
It is difficult to form acute angle, it is that rectangle is particularly disadvantageous to require section to the reception telltale hole of vertical arrangement.
The country can produce high-precision ultra-thin metal belting (such as Hangzhou Hai Ming metal products Co., Ltd has been at present
Through the strip that 2 μm of bandwidth of thickness are 0.99mm, the Shaanxi Chinese and new material Co., Ltd and Shenzhen perseverance space metal material can be produced
Material Co., Ltd can produce 6 μm of copper foils of thickness.), this is just that ultrasonic welding increasing material removes micro- 3D cavities top layer processing from
Condition is created, also due to strip thickness is less than the allowable error of micro- 3D cavities, it must be strip that can make 3D cavities headroom height
Thickness integral multiple this limit in elimination.
Both the strip (such as 0.01 or 0.02mm) for having made selection thickness slightly larger can also be compressed by controlling process dimension chain
The location dimension tolerance (in general location dimension tolerance is greater than geomery tolerance) of 3D cavities keeps top layer " ceiling " high
Degree is the integral multiple of strip thickness, and by the bottom electro-discharge machining to 3D cavities still can guarantee 3D cavities short transverse essence
Degree.
On the other hand it is exactly the general ultrasonic welding smaller of pressure ratio that thin material ultrasonic welding needs.If using the good roller of rigidity
Formula soldering tip, pressure act on entire affixed layer in cylindrical roller contact line, the pressure of original very little are made to be shared；In this base
Welding direction (vertical with hollow and hanging length direction as possible, i.e. the small direction of span) is also controlled on plinth reduces span；Again
In addition every layer process condition (amplitude, frequency, pressure, action time etc.) is consistent and (it is homogeneous to increase material).In addition, if 3D
Cavity dimension is small, then span is small, and thin slice is originally not easy that recessed filling occurs in micro- 3D cavities hollow space.It is all these, be all conducive to
Member Welding with 3D cavities increases material.
