Technical field
The utility model relates to a kind of being used for and adds the mould of thermal weld electrically non-conductive material from resistance, and the resistance certainly that is particularly useful for the small-sized mother metal of nonconducting of the same race and xenogenesis adds thermal weld.
Background technology
At present, in welding, can adopt several different methods heating mother metal and scolder, as the heating of stove silk, eddy-current heating, resistance heating etc. certainly.Be to make electric current pass through mother metal wherein, utilize the method for the resistance heated of mother metal itself from the resistance heating.It is simple that it has method, and firing rate is fast, and heating-up temperature and firing rate are convenient to advantages such as control.When adopting this method to weld nonconducting of the same race and xenogenesis mother metal, need to adopt the high density electrically conductive graphite make mould.When the electric current, graphite jig is from the resistance heating, and heat is delivered to nonconducting welding base metal and scolder then, to finish the welding of nonconducting of the same race and xenogenesis mother metal.Have common die now when the welding small sample, bending can occur, be difficult for locating the problems such as fixing that reach.
Summary of the invention
The utility model provides a kind of novel extraordinary composite graphite mould, uses this graphite jig can well be used for the welding of nonconducting of the same race and xenogenesis mother metal, especially for better than the small sample effect.
This graphite jig is made up of internal mold and external mold, it is characterized in that: internal mold and external mold are made up of the yin, yang mould respectively again, wherein place internal mold in the former of external mold, and formpiston one end of external mold is processed into truncated cone-shaped, and the other end is cylindrical; The former of internal mold is made up of the semicolumn of two hollows, wherein places material to be welded; On inside and outside two formers, have the aperture that location and thermometric are used.Adopt this composite graphite mould to weld, have welding base metal and scolder to load easily, weld that weldment takes out easily after finishing, mould is not easy to damage and can weld complex-shaped advantages such as electrically non-conductive material.
Description of drawings
Accompanying drawing 1 is the schematic diagram of described graphite jig outer die casing assembling structure.
Accompanying drawing 2 (a), 2 (b) show the formpiston structural representation of described graphite jig external mold.
