Description
Technical field
The present invention relates to a kind of superhard thin slice carbide alloy brazing processing method, belong to copper arc welding electrodes' technology field.
Background technology
At present, when carrying out superhard thin slice carbide alloy brazing, existing brazing technique cannot complete welding, following problem can be produced: 1, the spelter solder fusing point selected of existing copper Welding is higher, need heating spelter solder could be melted for a long time, cause carbide alloy heated time long, stress increases and ftractures.2, existing copper Welding is often empirically arranged when carrying out fit clearance convergent-divergent, and when causing gap to arrange excessive or too small welding, weld seam can pull open or fill insufficient.3, existing copper Welding does not add compensation copper sheet, due to very large stress can be produced in thin slice carbide alloy welding process, shrinkage stress can be made cannot to be released in weld seam and to concentrate generation tension, finally cause weld seam to pull open, carbide alloy time serious, also can be made to ftracture.4, do not use infrared thermometer to carry out temperature adjustment before the welding of existing copper Welding, during heating, temperature is uncontrollable, makes to add thermally labile, and there will be the too high workpiece that causes of temperature overheated, the temperature too low heat time is long, the problem that welding fusing point does not reach.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of superhard thin slice carbide alloy brazing processing method.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of superhard thin slice carbide alloy brazing processing method, comprises the steps:
Step one: select the spelter solder containing money base;
Step 2: install fixing superhard thin slice carbide alloy and steel part;
Step 3: by referring to the thermal coefficient of expansion of superhard thin slice carbide alloy, steel part, precision calculates and arranges the fit clearance of superhard thin slice carbide alloy and steel part;
Step 4: add copper sheet as compensating plate in fit clearance;
Step 5: use high frequency heating machine to heat superhard thin slice carbide alloy, steel part;
Step 6: superhard thin slice carbide alloy is welded with the spelter solder added in the fit clearance of steel part containing money base;
Step 7: add scaling powder in fit clearance;
Step 8: the workpiece after welding is placed in heat-preservation cotton and is cooled to normal temperature.
The described spelter solder fusing point containing money base is 690 DEG C-730 DEG C, and described superhard thin slice carbide alloy HRA is greater than 91, thickness 1-3mm.
When using high frequency heating machine to heat superhard thin slice carbide alloy, steel part, by infrared thermometer detected temperatures, control high frequency heating machine temperature is greater than the spelter solder fusing point 10 DEG C containing money base.
Described copper thickness is 0.1mm.
Beneficial effect: one provided by the invention superhard thin slice carbide alloy brazing processing method, owing to having selected the spelter solder containing money base, has made the heat time shorten, and heating-up temperature reduces, and substantially reduces the distortion of thin slice carbide alloy; Use infrared thermometer to carry out temperature control simultaneously, temperature is controlled more accurate; Rational gap is arranged, and workpiece is had and reasonably cools scale space; The increase of compensating plate effectively absorbs the stress in weld seam, and the tension that carbide alloy is born reduces greatly.
