Embodiment Construction

[0015] The DCMP aluminum alloy vacuum brazing machine case processing method of the present invention comprises the following steps:

[0016] The first step is to cut the material, select the rough material, and ensure that there is sufficient machining allowance;

[0017] The second step, heat treatment, annealing treatment, the purpose is to eliminate work hardening, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust structure, eliminate structure defects, and make the structure tend to balance ;

[0018] The third step is rough machining, leaving a finishing allowance of 0.5mm for the brazing mating surfaces of the left and right side panels, the rear side panel and the front frame, and the brazing mating surfaces of the left and right side panels and the heat dissipation fins. There is a finishing allowance of 0.5mm; the rear side panel and the front frame are left with a finishing allowance of 0.5...

Abstract

The invention relates to the field of machining, in particular to a machining method of a DCMP aluminium alloy vacuum soldering machine case. The method comprises the following steps: blanking, wherein a workblank material is selected, and enough machining allowance is reserved; thermal treatment; rough machining, wherein a finishing allowance of 0.5mm needs to be reserved between soldering fitting surfaces of left and right side plates and a rear side plate and a front frame, a finishing allowance of 0.5mm is reserved between the soldering fitting surfaces of the left and right side plates and cooling fins, and the rear side plate and the front frame are clamped and machined together according to a ganged manner in finish machining by respectively reserving a finishing allowance of 0.5mm at a single side in the length direction; finish machining; preparation before soldering; soldering; turning after soldering; removing redundant soldering material after welding; milling to remove technical allowance and technical bosses on a workpiece; drilling according to requirements; and carrying out surface treatment on the surface of the workpiece.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method for a DCMP aluminum alloy vacuum brazing machine case. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, shipbuilding, machinery manufacturing and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots of research. [0003] Due to the special requirement...
