Abstract
The utility model disclose a braze welding assembly structure for thick and thin plates. The braze welding assembly structure comprises a thick plate, a thin plate and a connecting plate, wherein the connecting plate is clamped between the thick plate and the thin plate; both the upper plate surface and the lower plate surface of the connecting plate are coated with welding flux; the thick plate, the thin plate and the connecting plate are clamped by using a clamp, and the plate surfaces of the three plates are placed into a vacuum braze welding furnace horizontally. Due to the adoption of a braze welding technology for the thick and thin plates, firm braze welding between the thick plate and the thin plate is realized, and weld lack points are avoided.
Description
Technical field
The utility model relates to Vacuum Soldering Technology field, especially a kind of thickness plate soldering assembly structure.
Background technology
Existing Aluminum Alloy Vacuum Brazing technology is all for the welding between 3003 materials.For the aluminium section bar vacuum brazing of two kinds of different conditions, also do not reach a technical level.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of thickness plate soldering assembly structure, has realized soldering between slab and thin plate and firmly without solder skip point.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
A thickness plate soldering assembly structure, comprises heavy-gauge sheeting, light sheet and is clipped in the connection sheet material between this heavy-gauge sheeting and light sheet,
On the upper face of described connection sheet material and lower face, all scribble scolder,
Described heavy-gauge sheeting, described light sheet and described connection sheet material are put into vacuum brazing furnace by the clamping rear plate face level of fixture.
A thickness plate soldering tech that is applied to described a kind of thickness plate soldering assembly structure, this technology comprises the following steps: the welding work pieces 1) described heavy-gauge sheeting, described light sheet, described connection sheet material and described scolder being formed is put in vacuum brazing furnace and vacuumizes; 2) described welding work pieces is heated and is incubated; 3) to described welding work pieces cooling;
Above-mentioned steps 1), in, vacuumize until vacuum reaches 4.0
-0.3pa or following;
Above-mentioned steps 2) in, be incubated 200 minutes after first described welding work pieces being heated to 450 ℃, then be heated to 540 ℃ of insulations 200 minutes;
Above-mentioned steps 3) in, keep described vacuum brazing furnace vacuum constant, welding work pieces is naturally cooling slowly with described vacuum brazing furnace, until described welding work pieces temperature reaches below 200 ℃, welding work pieces is taken out to vacuum brazing furnace and complete welding.
A kind of thickness plate of the utility model soldering tech, has realized soldering between slab and thin plate and firmly without solder skip point.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of thickness plate soldering assembly structure described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A thickness plate soldering assembly structure, comprise 6061 states heavy-gauge sheeting 1,3003 states light sheet 2 and be clipped in the connection sheet material 3 of 434 states between this heavy-gauge sheeting 1 and light sheet 2,
All scribble and fill scolder 4 connecting on the upper face of sheet material 3 and lower face,
Heavy-gauge sheeting 1, light sheet 2 and be connected sheet material 3 and put into vacuum brazing furnace by the clamping rear plate face level of fixture.
In welding process scolder 4 melt by cooling again solidify heavy-gauge sheeting 1, light sheet 2 and be connected sheet material 3 firmly hold tightly together.
A thickness plate soldering tech that is applied to a kind of thickness plate soldering assembly structure, this technology comprises the following steps: the welding work pieces 1) heavy-gauge sheeting 1, light sheet 2, connection sheet material 3 and scolder 4 being formed is put in vacuum brazing furnace and vacuumizes; 2) welding work pieces heated and be incubated; 3) welding work pieces is lowered the temperature;
Above-mentioned steps 1), in, vacuumize until vacuum reaches 4.0
-0.3pa or following, carries out to guarantee to be welded under the environment of high vacuum;
Above-mentioned steps 2) in, be incubated 200 minutes after first welding work pieces being heated to 450 ℃, then be heated to 540 ℃ of insulations 200 minutes, at utmost to reduce the temperature difference between the light sheet 2 of 3003 states and the heavy-gauge sheeting 1 of 6061 states;
Above-mentioned steps 3) in, keep vacuum brazing furnace vacuum constant, welding work pieces is naturally cooling slowly with vacuum brazing furnace, comes out of the stove below, to prevent that the sheet material of 6061 states from cracking until welding work pieces temperature reaches 200 ℃ again.
A kind of thickness plate of the utility model soldering assembly structure, has realized soldering between slab and thin plate and firmly without solder skip point.
