A processing technology of internal combustion engine radiator

Abstract

The invention discloses a machining process of an internal combustion engine radiator. The machining process comprises the following steps that S1, materials are selected; S2, blanking is carried out,and a water chamber and a clamping part at the lower end are integrally extruded and formed; S3, a core body is assembled; S4, the core body and the water chamber are assembled; S5, the core body andthe water chamber are compressed, and the clamping part and a main sheet in the clamping part are compressed through an extrusion device; S6, an end plate of the water chamber is assembled; S7, a reinforcing plate is assembled; and S8, brazing forming is carried out. According to the machining process of the internal combustion engine radiator, the welding quality can be improved, the water testing and pressing qualification rate is increased, and the one-time pressing qualification rate reaches 98% or above; the assembling efficiency of the aluminum water chamber and the main sheet is improved, and the forming period of the radiator is shortened; the automation level is improved, manual operation is reduced, and the yield of radiator finished products is not limited by argon arc weldingworkers; and compared with other processes, the appearance of the product is more attractive.

Description

technical field [0001] The patent of the present invention relates to a processing technology of an internal combustion engine radiator, which belongs to the technical field of heat exchange equipment. Background technique [0002] At present, radiators for construction machinery, generator sets, various heavy trucks and light trucks include water chambers and cores. The cores are assembled from main sheets, heat pipes, heat dissipation belts and reinforcing plates; The material is aluminum or carbon steel, the aluminum water chamber and the main piece are connected and sealed by argon arc welding, and the carbon steel water chamber and the main piece are connected and sealed by bolts and gaskets. [0003] The general process of the manufacturing process of the existing aluminum water chamber radiator is as follows: assemble the heat dissipation pipe, the heat dissipation belt and the main piece, and after the assembly is completed and passed the inspection, put the core bod...

AI Technical Summary

Problems solved by technology

[0004] 1. The pass rate of radiators connected by argon arc welding is low. When the pressure test pressure is 0.125Mpa, the pass rate of radiators is only 90%~92%, and the pass rate of radiators is limited. Due to the skills of argon arc welders, the welding quality is unstable and welding defects are prone to occur;

[0005] 2. The assembly efficiency of the aluminum water chamber and the main piece is extremely low, which in turn affects the molding cycle of the entire radiator;

[0006] 3. At present, there is an extreme shortage of argon arc welders with qualified operation skills, which has become the bottleneck link in the entire radiator production process, and the output of finished radiators is restricted;

[0007] 4. The appearance of the argon arc welding seam is poor, which affects the appearance
