Problems solved by technology

The problem brought by this method is that the gap between the flanged hole and the outer wall of the nozzle becomes uneven, and the closer to the flanged hole, the larger the gap is, and the maximum gap reaches more than 0.1, which exceeds the allowable vacuum brazing The largest gap causes false welding near the flange orifice; and after the nozzle is flared, the height of the welding surface area is only about 1mm, and the welding strength is low, which cannot meet the product use requirements

Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0038] like figure 1 As shown, the existing IGBT radiator includes a rib plate 101, the rib plate 101 is the cover plate and the bottom plate of the radiator, a corrugated plate is provided between the two, and a flange hole is provided on the rib plate 101. The nozzle 102 is inserted into the flange hole, so that the radiator can be assembled through multiple parts, and vacuum brazed to form a whole, and a plurality of round holes 103 are set on the rib plate 101, and the rib plate 101 and the corrugated plate are required for welding. The shape of each circular hole 103 holes on it and its position coincides with each other.

[0039] like Figure 2-Figure 11 As sh...

Abstract

The invention discloses a method and tool for improving the bonding rate of a pipe nozzle and a rib plate flanging hole. The method is an improvement of an existing radiator nozzle and rib plate flanging hole welding method, and is combined with the corresponding tool, so that the pipe nozzle and the flanging hole are assembled in a press-fitting manner without flaring riveting. During welding, the pipe nozzle faces downwards, so that the welding quality is better; the end face of the pipe nozzle is supported with the combination of a supporting mechanism additionally arranged on the tool, sothat the pipe nozzle is prevented from falling under the action of gravity during welding, and the operation is very convenient and efficient. The method is simple in structure, low in cost and high in operation convenience. With the combination of the corresponding tool, assembly of parts of a radiator can be efficiently completed, time and labor are saved during assembly, high assembly precisionof the parts is ensured, welding and positioning requirements of products are met, the welding intensity is obviously improved, the welding quality is good, the service life is long, and the yield offinished products is high.

Description

technical field [0001] The invention relates to a method and a tooling for improving the welding rate of a nozzle and a flange hole of a rib plate, and belongs to the technical field of radiator manufacturing. Background technique [0002] Aluminum oil coolers and radiators are being manufactured more and more by vacuum brazing technology. In this type of products, there are a large number of matching welding structures between nozzles and flanged holes of rib plates. At present, the nozzle and the flange hole of the rib plate are usually brazed after being riveted and positioned. The specific steps of this method are: first insert the nozzle into the flange hole of the rib plate, and fix the nozzle on the Rib plate; vacuum brazing technology is used to realize the welding of the insertion parts of the two. The problem brought by this method is that the gap between the flanged hole and the outer wall of the nozzle becomes uneven, and the closer to the flanged hole, the larg...
