The air entry flushed with workbench, the air entry are connected to air pump by tracheae.Air entry can be multiple individual air-breathings
Channel forms, and in each independent air intake passage setting valve, is opened or closed multiple valves according to the shape of part
In it is several；Can also be one main air intake passage of setting in the range of fixed area, by the fixation of target part unit in this model
In enclosing.
As shown in figure 4, due in the welding process, the accurate positionin of first layer part is to each layer of target part thereafter
Positioning effects are most important, therefore on welding bench 11, there is provided alignment system, and establish in the controls opposite
The coordinate system positioning of entire part position.When successively being welded, the lift platform 13 of 11 lower section of welding bench moves down
One unit materials thickness distance, the distance for making next layer of soldering part to electromagnetic spool device 10 are identical with last layer welding.
And the cutting of second layer part component 12 of target part at this time finishes, raw material transmission recovery system 4, which takes rotation out of, has cut
Into the second layer part component 12 of target part be transported to part crawl point, it is accurate that Suction cup assembly 8 is back to part crawl point top
It is standby that the second layer part component 12 of target part is transported.The positioning device of air-breathing is used in the present invention, by part
Negative-pressure adsorption, it is ensured that part positioning it is accurate.
The air pump of this alignment system shared in the form of in parallel with the air pump of Suction cup assembly a total air pump or that
This mutually independent air pump controls independently of one another；In addition the air pump of dust pelletizing system and the air pump of alignment system, the gas of Suction cup assembly
A total air pump is shared in the form of in parallel or the respective air pump of three is mutually independent between pump three, it is unlimited herein
The relationship of fixed above each air pump.
Fig. 5 is the process schematic of the follow-up electromagnetism welding of part in the present invention.Suction cup assembly 8 is moved the of target part
Two layers of part component 12 transport 11 top of welding bench, are positioned on the first layer part component 7 of target part and carry out electricity
Magnetic welds.Due to having to that one initial velocity of welded part is supplied to ensure welding result in electromagnetism welding process, so
Between weldment and welded part, speed locating piece 14 is placed with reserved space, it is ensured that in electromagnetism welding process, welded part is in wink
When pulses generation magnetic field force under the action of obtain certain stroke speed, ensure that welding process is efficient, welding result is good.Speed
Degree locating piece 14 be the thin-wall part of insulation, in process by the addition of the manual operation speed locating piece with taking away, addition
Position set by the needs of pad, do not limit herein.It is produced in the welding process in order to reduce electromagnetic spool device 10
The energy loss in raw magnetic field should ensure electromagnetic spool device 10 close to welding material surface as far as possible.
Fig. 6 illustrates the electromagnetism welding process of the target part participated in speed locating piece 14.To ensure welding effect,
The top of first layer part component 7 of target part place two pieces (or polylith, is designed according to the needs of pad, herein for
Approximate number) speed locating piece 14, the second layer part component 12 of target part transports and is positioned over speed locating piece by Suction cup assembly 8
On 14, electromagnetic spool device 10 is controlled to move to above welding material through three axis tracks 9 by control system 1 and carries out magnetic discharge welding and take over
Journey.The second layer part component 12 of target part slamming down target part under the action of the magnetic field force of high speed magnetic pulses generation
First layer part component 7, be combined with each other between atom at contact interface so as to fulfill welding, welding removes speed after completing
Locating piece 14.Due to electromagnetism welding high speed instantaneity, thus the air moment between two block of material be extruded and to form vacuum, so
Welding effect is good, and because electromagnetism welding process heat production is few, and temperature is not specially required, so solder bond interface will not
There is brittle intermetallic compound, can realize good welding effect.

Material transmission recovery system is four-wheel transport mechanism.Expansion tightening wheel include positioned at stock roll and Cutting platform between feeding pair volume with
And the active between Cutting platform and recycling volume is rolled up, metal tangent with the table top of Cutting platform is rolled up in feeding pair volume and active
Band is wrapped in stock roll, is recycled on volume by feeding pair volume, active volume, final be wrapped in successively, by recycling volume rotation, pulling
Metal tape travel, feeding pair volume and active are rolled up in the process plays the role of tensioner to entire metal material belt, ensures cutting
In the process, the size of target part unit is accurate, dimensionally stable.
In addition, after in order to ensure cutting, it is located away from whole part and is not fallen out before sucker crawl, cutting is flat
The length of platform is set as including at least two sections of stations, cutting work station and sucker station.
The present apparatus further includes control system, is controlled using PLC editing machines.
As shown in figure 11, propose a kind of manufacturing process for replacing traditional 3D printing in the present invention, forming speed is fast, into
Shape effect is good, can meet in the market to customized product gradually increased demand, and cost is far below existing 3D printing work
Skill.Forming process mainly is divided into laser cutting for this manufacturing process and electromagnetism welds two parts, and two parts interaction improves
