Description
Technical field
The present invention relates to radiator manufacturing technology field, be specifically related to the method that the seam of the partition of a kind of automobile radiators with bilateral hydroecium, hydroecium and core body connects.
Background technology
The bilateral hydroecium of full aluminum automobile radiators and core body welding procedure, it is common that by bilateral hydroecium integrated punching molding, insert partition lead welding and shaping between hydroecium and core body, or be welded in by partition by hand inside integrated hydroecium again by hydroecium and core body welding fabrication.In actual mechanical process, stamping forming partition exterior contour is difficult to closely cooperate with the in-profile of hydroecium and core body composition, easily there is the partition place phenomenon by water under high pressure lateral low setting-out side seepage as an integral solder in bilateral hydroecium, seepage within this radiator not easily checks and repairs, coolant can reduce the heat dispersion of radiator without the core body direct short-circuit flowing of radiator, by client, the product of partition place leakage can be thought that substandard product is rejected.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide one can effectively prevent bilateral hydroecium partition place Seepage, improve conforming product rate and reduce the full aluminum automobile radiators welding method with bilateral hydroecium of part difficulty of processing.
The purpose of the present invention can be achieved through the following technical solutions: a kind of full aluminum automobile radiators welding method with bilateral hydroecium, it is characterized in that, the method is that stamping forming bilateral hydroecium is divided into two independent parts, the divisional plane place of bilateral hydroecium arranges partition, partition and main leaf being tightly connected by full weld, the bilateral hydroecium of segmentation is in the welding of partition place and seals seam with partition.
Described method specifically includes following steps:
A. the core body of radiator) pass through lead welding and shaping；
B. the hydroecium that core body both sides connect is by mould punching molding, and bilateral hydroecium is divided into two independent parts in core body shunting place；
C. the Part I spot welding of bilateral hydroecium is fixed on core body, and the divisional plane place spot welding shunting partition between Part I and second of bilateral hydroecium, makes shunting partition and bilateral hydroecium fix, and welding taps partition and main leaf, and checks sealing；
D. the Part II of the fixing bilateral hydroecium of spot welding, docks two parts of bilateral hydroecium and welds with shunting partition sealing；
E. welding bilateral hydroecium is connected with main leaf, and other parts.
Stamping forming bilateral hydroecium is divided into two independent parts at core body divided fluid stream place.
The appearance profile of described shunting partition is consistent with the profile that the main leaf of bilateral hydroecium and core body surrounds, weld seam a shunting partition and main leaf are tightly connected.
Part I and the Part II of described bilateral hydroecium connect into entirety by weld seam b.
Compared with prior art, the present invention adopts the segmentation welding of bilateral hydroecium, docks hydroecium more integral after shunting partition welding.Partition position between core body bank of tubes can be accurately positioned, and shunting partition easily checks tightness with welding of main leaf and takes repair operation, and first spot welding location is welded and can be effectively reduced thermal expansion deformation in welding process to the welding at two ends in the middle of hydroecium.
The full aluminium radiator with bilateral hydroecium that the method for the present invention makes, can reliable fluid partitioning at partition place, ensure not reduced by the fluid of core body and improve radiator performance, also reduce the requirement to partition and hydroecium cooperation place parts size precision, simplified the difficulty of processing of corresponding diel.
Accompanying drawing explanation
Fig. 1 is the full aluminium radiator structural representation of bilateral hydroecium of the present invention；
Fig. 2 partition welds schematic diagram with main leaf；
Fig. 3 bilateral hydroecium segmentation docking also welds schematic diagram with partition.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, the present invention includes just overall stamping parts hydroecium 3 and is divided into two independent sectors at weld seam b7 place shown in core body 1 divided fluid stream place and Fig. 3, after first Part I hydroecium being in place, it is fixed in the draw-in groove of main leaf 6 by the method for spot welding, shunting partition 4 is placed into the open end of standing part hydroecium again, top spot welding and hydroecium location, shunting partition 4 is connected such as weld seam a5 with main leaf 6 joining part full weld, and check that sealing is qualified by light transmission, again Part II hydroecium is in place spot welding to fix, connect by weld seam b7 full weld in segmentation portion, then again by hydroecium and main leaf full weld, weld other again such as adnexaes such as water pipe heads.
The manufacture method processing step of above-mentioned full aluminium radiator is:
A. lead welding and shaping after being assembled by core body 1, this is normal conventional technology；
B. tapping partition 4 and bilateral hydroecium 3 punch forming by mould, this is normal conventional technology, but the fitted position required precision at partition place is relatively conventional relatively low；
C. 3 one-tenth two independent parts of shunt position sized divisions bilateral hydroecium according to design；
D. the hydroecium after the fixing Part I segmentation of spot welding, then shunting partition 4 is in place spot welding is fixed on hydroecium end face；
E. the faying face of full weld shunting partition 4 and main leaf 6, and check weld seam tightness；
F. Part II hydroecium is in place rear spot welding to fix；
G. hydroecium welded seal bilateral hydroecium 3 and shunting partition 4 joint face are docked at bilateral hydroecium 3 segmentation portion full weld；
H. full weld bilateral hydroecium 3 and main leaf 6 faying face, and other adnexa such as water pipe head.
Flow working medium in described radiator can be water, or anti-icing fluid, or compression air, or wet goods medium, and radiator title can be water tank, oil cooler, charge air cooler etc., and manual welding can be argon arc welding but be not limited to use argon arc welding.The material of radiator can be aluminum and aluminum alloy mateial, it is possible to be other metal material adopting this processes.
