Summary of the invention
In view of this; The purpose of this invention is to provide a kind of oil cooler core assembly welding procedure; Avoid adopting the tin lead welding to add the mode of scaling powder, select different welding technology, with the intensity and the stability of the welding position that improves machine oil cooler core according to unlike material; To eliminate user's fault of oil cooler assembly, prolong the service life of product.
The objective of the invention is to realize through following technical scheme: a kind of oil cooler core assembly manufacturing process may further comprise the steps:
A, machining base plate and water storage bowl evenly plate copper cyanider at base plate and water storage bowl surface then;
B, machining joint and the water storage bowl lid that discharges water, the welding manner of will discharge water then joint and water storage bowl lid employing brazing is fixedly connected, and joint and water storage bowl cap surface evenly plate copper cyanider discharging water;
C, assembling fuse heat radiation position;
D, assembling plate, water storage bowl and heat radiation position, the mode of employing copper phosphorus soldering are welded with the water storage bowl two ends of fuse radiating tube respectively and are fixedly connected with base plate;
The mode of e, employing carbon-dioxide arc welding is welded on water storage bowl lid can obtain oil cooler core assembly of the present invention on the water storage bowl.
Further, between steps d and step e, also comprise steps d
1: pressure test, dimensional gaughing;
Further, after step e, also comprise step f: pressure test, size, visual examination.
Beneficial effect of the present invention: the first, in the employing brazing mode between joint and the water storage bowl lid (steel to steel) that discharges water, because receive the welding position shape affects of water storage bowl lid; Analysis to welding efficiency and welding position working strength; Adopt brazing mode welding efficiency high, good stability does not have and leaks.The second,, low between water storage bowl and the water storage bowl lid with traditional brazing mode weld strength because the welding position is little, be prone to dry joint, rosin joint, welding efficiency is low, appearance poor; Adopt after the carbon-dioxide arc welding mode of the present invention's qualification, welding efficiency improves, and weld strength increases, and welding stability is good, does not have and leaks.The 3rd, (steel plating copper cyanider plates copper cyanider to steel) all adopted the mode of copper phosphorus soldering between fuse radiating tube and water storage bowl, the base plate, compares the copper facing of available technology adopting or plates other metal auxiliary layers; Steel surface plating copper cyanider layer is not only high temperature resistant, and adhesion strength is high, difficult drop-off; Therefore between steel plating copper cyanider is to steel plating copper cyanider, adopt the mode of copper phosphorus soldering, weld strength improves greatly, has reduced dry joint, rosin joint phenomenon; Cancelled the scaling powder that corrosiveness is arranged; Improve the intensity and the stability of welding position, got rid of user's fault of oil cooler assembly, prolonged the service life of product.
