By insulation board 12, the processing platform 13 of lathe is made to be separated with circuit, ensures that electric current flows to hair from forming tool head
Blank 6 or metal blank 14.
By being full of compressed nitrogen in blank cavity 16, structure is similar to nitrogen gas spring, utilizes compressed nitrogen and ball
More critically control tool heads improve precision to stroke to the pressure of plate.
Leakproofness when piston 2 moves back and forth is improved by sealing ring 3.
By machining tool head 11 scratch part of machining tool is prevented for flexible structure.
Fig. 1 is the progressive molding machining sketch chart in plate type face, progressive in numerical control using the processing method of negative forming
It is processed on forming machine tool, first uses plate shearing machine, lower two block plates, plate cutting that should stay certain cutting surplus, flitch, processing
Tool heads 1 and power supply constitute the circuit of a closure, using the resistance of plank itself, generate joule's heat energy, make it to reaching
Shape temperature.After temperature reaches requirement, machining locus movement of the machining tool head 1 on NC control each contour layers of lower edge, by
Layer processing, finally processes 1 part of metal blank in required type face.
After upper and lower metal blank 1 shapes, argon arc welding soldering and sealing is carried out to two metal blanks, 1 material, and weld a titanium tube
8, to prevent welding deformation, welding fixture should be used, upper and lower metal blank 1 is made to be welded in the state of clamping.
Diffusion connection still realizes that, by the good panel surface coat coating of soldering and sealing, coating can using Metal CNC Incremental Forming lathe
It being watered and is stirred to get according to a certain percentage using boron nitride and graphite powder, the effect of coating is lubrication and prevents oxygen uptake from absorbing hydrogen,
After drying to be coated, metal blank 14 is placed in device shown in Fig. 2, connection vacuum pump 9 first starts vacuum pump, to soldering and sealing
It is vacuumized in good blank cavity 16, ensures to be in vacuum state in blank cavity 16, be full of compressed nitrogen in blank cavity 16,
Structure is similar to nitrogen gas spring, and machining tool head 1 is more critically controlled using the stroke of compressed nitrogen and ball 4 to blank
6 pressure.
After clamping, machining tool head 1 is contacted with blank 6, and power supply is powered, and 6 temperature of blank reaches diffusion connection
After temperature, machining tool head 1 pushes a distance, and ball 4 makes 2 compressed nitrogen of piston, to which compressed nitrogen transmission pressure is anti-
It acts on to blank 6, ball 4 keeps such stroke, and is moved along machining locus under the control of NC, and movement locus covers
The region of lid diffusion connection, unlike progressive molding, machining tool head 1 does not have to layered rolling, only need to be maintained at setting
Machined layer, the surface treatments such as quick-fried pickling of 0 alkali, can also carry out surface polishing.Two-ply constitutional detail is thus obtained.
The specific implementation mode of the application above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the application protection domain therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, under the premise of not departing from technical scheme design, various modifications and improvements can be made, these belong to this
The protection domain of application.
