Workbench 10: fixing workpiece 11, and can perform to rotate and one-dimensional banking motion.
The work process of this utility model wire feed type electron beam increasing material manufacture equipment:
The first step: set-up procedure, including wearing silk, fixing substrate, evacuation and generation technological parameter.
1. wear silk: wire tray 32 is hung on support 31, pull out wire belt 33, allow wire belt 33 sequentially pass through butt welding machine
34, dynamic sealing device 35, trough 9 and wire-feed motor 36 are gone directly below electron gun 8.
2. fixing substrate: be fixed on workbench 10 by one piece of metal basal board, workpiece 11 will grow on this metal basal board
Out.The composition of metal basal board is consistent or close with the composition of workpiece 11.
3. evacuation: close vacuum chamber 6, starts cooling system, start successively vacuum pump unit 51 and electron gun point
Sub-pump, until vacuum chamber 6 internal vacuum and electron gun 8 internal vacuum all reach job requirement.
4. technological parameter is generated: central control unit 1 is processed by data according to the three-dimensional CAD model of workpiece 11 to be manufactured
Software carries out hierarchy slicing process, forms machining locus；After setting electron beam parameter and wire feed rate, data processing software is automatic
Generate nc program.
Second step: manufacture workpiece.
After the vacuum condition of vacuum chamber 6 reaches, the power supply starting electron gun 8 produces electron beam 83, is formed on workpiece 11
Molten bath, telecontrol equipment 7 drives electron gun 8 and wire-feed motor 36 to move and/or workbench 10 drives workpiece 11 to rotate, tinsel simultaneously
Band 33 melts under electron beam 83 acts on, and piles up according to predetermined machining path.
Often having manufactured one to fix segment and manufacture after layer 12, electron beam 83 the most quickly scanning is as shown in Figure 2.Scanning area 13
The invariant position of opposing electronic rifle 8, is controlled scanning area by central control unit 1 by controlling the exciting current of inclined sweeping device 81
Each point secondary electron signal on the scanning track in territory 13, and synchronous recording scanning track.After the end of scan, central control unit 1
It is analyzed processing to the secondary electron signal data of record, it is judged that whether the edge manufacturing layer 12 in scanning area 13 reaches uncommon
Prestige value, and judge whether scanning area 13 interior manufacture layer 12 exists cavity blemish, in order to repair in time.
After completing a manufacture manufacturing layer, electron gun 8 rises a level altitude manufacturing thickness, carries out a upper system
Making the manufacture of layer, each interlayer that manufactures forms metallurgical binding, piles up layer by layer.
3rd step: change silk.
Central control unit 1 detects that the wire belt 33 in wire tray 32 has been used up just to send soon and changes silk prompting, closes simultaneously
Closing electron beam 83, stop wire-feed motor 36 wire feed, stop motion device 7 and workbench 10 move, and central control unit 1 have recorded punching
Breakpoint information.Now wire tray 32 more renews, and wire belt 33 is welded together by butt welding machine 34, and pad is carried out at deburring
Reason so that solder joint smooths.Change silk and terminate rear central control unit 1 from thrusting a repetition second step job.If in wire feed system
Set up steel wire storage device, then a process of changing just is not required to interrupt the manufacture work of workpiece 11.
4th step: workpiece cools down.
Workpiece 11 manufacture process constantly repeats second step and the 3rd step until producing required workpiece 11, is then shut off electricity
The power supply of sub-rifle 8 and stopping wire feed system working, and stop motion device 7 and workbench 10 move, vacuum pump unit 51 and cooling
Liquid circulating device 41 keeps on the go state.The workpiece 11 manufactured cools down under vacuum conditions, and cool time is set by technological requirement
Fixed.Cooling terminates, and stops vacuum pump unit 51 and coolant circulation unit 41 works, and finally takes out workpiece 11.
Additionally this utility model electron beam increases material manufacture equipment employing built-in electronic rifle structure, is conducive to improving vacuum chamber
Utilization rate.But the electron beam using external electron gun structure increases material manufactures equipment, if using secondary electron signal to monitor system
Make process technology and use external dynamic seal wire feed technology to broadly fall into this utility model protection domain.
