Body opens the regulating valve in water fuel oxyhydrogen machine flame gun, after hydrogen and oxygen mixture after the ejection of choked flow nozzles, with lighter point
Combustion；
(2) each wax-pattern component of wax pattern assemblies is taken：Sprue cup wax-pattern, shunting disk wax-pattern, six cross gate wax-patterns with
And six circular arc feeding head wax-patterns, water fuel oxyhydrogen machine flame is allowed in the quick migration of each wax pattern surface, flame combustion generation
High temperature can allow its surface wax bed of material melt, to the flow liner on its surface, overlap, burr, hole and it is coarse the defects of carry out
Quick to repair, the single dead head surface after reparation is smooth and defect removal is thorough；
(3) water fuel oxyhydrogen machine flame gun is aligned to the baseplane of shunting disk wax-pattern, choked flow nozzles is kept to justify with shunting
Disk wax-pattern need to keep the distance of 20-30mm, and the wax material layer that the baseplane of disk wax-pattern will be shunted with its flame melts, by each horizontal stroke
Running channel wax-pattern is adhered to simultaneously on the baseplane of shunting disk wax-pattern；
(4) according to the same method of such as step (3) by the lower surface of sprue cup wax-pattern, circular arc feeding head wax-pattern up and down
The surface wax bed of material is respectively melted, and by sprue cup wax-pattern with shunting disk wax-pattern, each cross gate wax-pattern and each circular arc feeding
Riser wax-pattern is bonded successively, and finally assembled each wax-pattern is adhered on guide vane wax-pattern, obtains completely group tree；
(5) water fuel oxyhydrogen machine flame gun is directed at assembled group of all welding surfaces of tree, to its weld seam, wax stream, fash
Position, using flame melting welding, including the group tree dead angle position that various specifications electric heating welding knife can not touch, water combustion can be used
Expect that oxyhydrogen machine carries out flame melting welding.
The host and flame gun that the water fuel oxyhydrogen machine includes are linked together by rubber hose；Host is equipped with electricity
Flow table, pressure gauge, flame gun are equipped with regulating valve.
The water fuel hydrogen-oxygen machine host electrolyte inside presses 4 by water and sodium hydroxide electrolytic powder:1 proportional arrangement, mistake
It is distilled water or alcohol to filter solvent.
(3) advantageous effect
The present invention provides a kind of methods using water fuel oxyhydrogen machine investment pattern precision casting wax pattern assemblies.Possess following beneficial to effect
Fruit：
Water fuel oxyhydrogen machine is applied in precision-investment casting wax pattern assemblies, the fire generated with hydrogen and oxygen mixture burning
Flame group tree, can organize multiple ingates of the tree in same welding surface simultaneously, and group tree work efficiency greatly improves；Wax during group tree
Liquid transient melting, wax liquor will not be carbonized, the wax cigarette very little that group tree generates in the process, and group tree shopwork environment has to be changed greatly very much
It is kind；And it can be quickly repaired at flow liner on each wax pattern surface, overlap, burr, hole and cast gate welding surface
Gap, wax stream, fash the defects of, each wax pattern surface after repairing is smooth and defect removal is thorough, to the product of rear process
Quality provides effective premise.
