Specific embodiment
The integral formation method of the uniform air conditioning connector of solder layer of the present invention, it is characterised in that including:
The step of making blank：Raw material plate is bought from market, raw material plate is three layers of complex layered plate, and intermediate layer is aluminium alloy
Layer, thickness is 4.2mm, and the upper and lower are pincers solder layer, and thickness is 0.5mm.
Raw material plate cutting is made into circular, a diameter of 27mm, and centre bore 101 is provided with center, aperture is 8mm, this
Sample has just been fabricated to blank 100 as shown in Figure 3.
The step of making upper die and lower die：
As shown in Figure 4 and Figure 5, the upper mould 200 being fabricated to includes upper die body 210, is connected to the compression leg of the lower section of upper die body 210
220 and it is connected to the drift 230 of the lower section of compression leg 220.
Wherein, the end face of compression leg 220 has the annular groove 221 around drift 230 and the forming ends around drift 230
Face 222.The annular groove 221 is used to be molded the centring ring of air conditioning connector, and shaping end face 222 is used to be molded air conditioning connector
The curved weld face of flange connector.Specifically, shaping end face be symmetrically upturned for both sides, middle downward projection of arcwall face,
Shape is corresponding to the shape in the curved weld face of the flange connector of air conditioning connector；The bottom surface of annular groove the root of drift with
Be molded end face shape rise and fall and be circumferentially spaced apart shaping air conditioning connector centring ring positioning convex into
Type pit 223；
The lower end of drift 230 has cone-shaped end 231, and the height of cone-shaped end 231 is 13mm, and taper is 60 degree.Drift
230 diameter is identical with the internal diameter of the body of connector.
The lower mould 300 produced such as Fig. 6-Fig. 8 has interconnected upper circular hole chamber 310 and lower circular hole chamber 320, upper circular hole
Smoothly transitted by arc forming surface 330 between chamber 310 and lower circular hole chamber 320；Arc forming surface 330 is used to be molded air-conditioning connection
The flange connector outer surface of device.Specifically, arc forming surface 330 is upturned for both sides, centre is to lower recess, shape and air-conditioning
The flange connector outer surface of connector is corresponding.The diameter in circular hole chamber 310 be able to be put into blank 100 on air-conditioning, and base is accomplished as far as possible
Upper gap between circular hole chamber 310 and blank 100 is minimum after material 100 is put into, as long as blank 100 can be put into upper circular hole chamber
In 320.The diameter in lower circular hole chamber 320 is identical with the diameter of the body of connector.
To reduce burr, the compression leg 220 of the upper mould 200 of making is more smaller than the diameter in the upper circular hole chamber 310 of lower mould, but to use up
Gap behind the upper circular hole chamber 310 of the amount reduction entrance of compression leg 220 between the two, as long as ensureing that compression leg 220 can smoothly enter upper circular hole
In chamber 310, in the present embodiment, the gap substantially 0.1mm.
Punch forming step：
Blank 100 is placed into the upper circular hole chamber 310 of lower mould 300 so that the warping part pair of the shaping end face in upper mould
The warping part of the arc forming surface in the lower mould of standard, mould 200 is pushed in driving, allows the cone-shaped end 231 of drift 230 to be introduced into blank
In 100 centre bore 101 so that the material around centre bore downwardly and outwardly expands flowing, until drift 230 is completely into blank
In, then proceed to push again so that the compression leg 220 of upper mould 200 is matched somebody with somebody with the upper circular hole chamber 310 of lower mould 300 and arc forming surface 330
Combined pressure goes out the shape of the flange connector of connector, forms semi-finished product；
Pressure when upper punch is pressed is 50T, and speed is 10cm/s.
Semi-finished product edge is modified with the mode pruned and polish, is fabricated to air conditioning connector.
Air conditioning connector to being fabricated to is taken pictures, and photo as shown in Figure 9 is obtained by taking pictures as can be seen that air-conditioning
Solder layer on the curved weld face of connector and the outer surface of body is evenly distributed.
But, those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
Invention, and be not used as being limitation of the invention, as long as in spirit of the invention, to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
