Specific implementation step
The present invention is described in further detail below.
Referring to Fig. 2, the high-frequency induction brazing device of aluminum bronze soldered fitting of the present invention includes heating element heater 7, high-frequency induction
Coil, workbench 5, base 4, solder 6.Wherein, the workbench 5 is arranged on base 4, and heating element heater 7 is arranged on work
Make on platform 6.The heating element heater 4 is divided into the essentially identical two parts of profile, size, and a part is used to place Heated Copper end
Son, another part are used to place heating aluminium bar.The radio-frequency induction coil is divided into coil 1 and the two parts of coil 2, two coils
Shape, frequency and electric current are identical, are looped around two parts that heating element heater is used to heat copper tip and aluminium bar respectively.
The heating element heater is the high ferrous metal of unit permeance, such as iron or steel or stainless steel, in radio-frequency induction coil
It can be rapidly heated under effect.
In addition, below the heating element heater, flitch is provided with base, for the solder fallen under collection.
The present invention changes the mode of heating that copper element in aluminium joint is directly heated using radio-frequency induction coil, is changed into high-frequency induction
Coil first heats the high heating element heater of steel, stainless steel equimagnetic coefficient of conductivity, then again in a manner of heat transfer or heat radiation between
Connect Heated Copper element in aluminium joint.Since so, when being heated, heating element heater can be as the thermal source of soldering, when stopping
When only heating, heating element heater can be incubated to copper element in aluminium joint, so as to improve the quality of soldered fitting.
The high-frequency induction brazing method of copper element in aluminium joint of the present invention is given below, its detailed process is as follows：
Step 1: material prepares
Engineer testing sample is got in warehouse, checks whether pattern is consistent for part verification of conformity.Solder and brazing flux should have
Acceptable quality proves.
Step 2: welding preparation.
The joint edges of part should go flash removed and careful backfit.The welding region of part carries out soak cleaning or machinery is clear
Reason, ensure institute's cleaning area oxide-free, greasy dirt and other exotics.
Step 2: welding
