Radiator brazing device with roller type conveying mechanism

Abstract

The invention relates to the technical field of radiator brazing equipment, and provides a radiator brazing device with a roller type conveying mechanism. The radiator brazing device comprises a heating box, and the heating box is internally provided with a conveying mechanism for conveying a radiator core; an induction coil is arranged in an interlayer of the box wall of the heating box; a plurality of rows of nozzles are arranged on the inner wall of the heating box; each row of nozzles are uniformly distributed in the range of 0-180 degrees of the inner wall of the heating box; and the conveying mechanism comprises a plurality of conveying rollers which are arranged on the same horizontal plane in parallel and rotate in the same direction at the same speed. Therefore, the conveying mechanism is formed by the plurality of conveying rollers which are arranged on the same horizontal plane in parallel; and by arranging the nozzles above and below the conveying rollers, brazing flux andbrazing filler metal are sprayed to the radiator core in the upper direction and the lower direction, so that welding flux can be fully arranged at all welding points of the radiator core, the occurrence of desoldering points is greatly reduced or even avoided, the workload of repair welding operation is greatly reduced, and the production efficiency and the product quality are improved.

Description

technical field [0001] The invention belongs to the technical field of radiator brazing equipment, in particular to a radiator brazing device with a roller conveying mechanism. Background technique [0002] see figure 1 , the current radiator core 1 is brazed, usually the radiator core 1 is placed on the conveyor belt 100 (usually a metal mesh belt), and then sent to the brazing furnace. In the high temperature environment of about 600°C in the brazing furnace, the aluminum fixing plate 11 tends to become soft and deformed under the action of the radiator core 1's own weight. [0003] Before the assembly process, the deformed fixing plate 11 needs to be shaped, which increases the production process and prolongs the production cycle. Part of the fixing plate 11 with serious deformation may even cause waste products, which increases the production cost. [0004] During brazing, it is necessary to spray flux and brazing material to the radiator core 1, because the metal mes...

AI Technical Summary

Problems solved by technology

Due to the many solder joints of the radiator core 1, desoldering often occurs at the junction of the heat dissipation belt and the cooling pipe after brazing, which affects the heat dissipation function

At present, manual inspection is carried out after brazing, and repair welding is performed on desoldered or unsoldered points, which increases manufacturing costs and affects production efficiency

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
