Embodiment

[0027] see figure 2 First, with the part 10 to be coated with brazing material as the main body, the brazing top cover 11 is installed on the corresponding position on the part 10; secondly, the prepared brazing material is placed in the medical syringe 8, and the syringe is used to Tighten the interface 9; again, turn on the switch 1 of the semi-automatic coating equipment, connect the compressed air pipeline to the compressed air inlet 2, adjust the compressed air adjustment knob 3 to the process range, and then adjust to the required pressure through the compressed air fine-tuning knob 6. The compressed air outlet 5 is connected to the parts for applying brazing material; finally, after the brazing material at the tip outlet 7 of the brazing material is uniformly and stably discharged, the installed brazing top cover 11 can be applied. And apply in a clockwise / counterclockwise direction along the perimeter of the top cover.

Abstract

The invention discloses a vacuum brazing semi-automatic brazing material coating method. The vacuum brazing semi-automatic brazing material coating method particularly comprises the following steps: 1) proportioning a brazing material, brazing glue and a diluent according to the ratio of (120-140):(20-30):1, stirring with a spoon and blending into paste; 2) charging: charging the blended brazing material into a medical injector; 3) preparing coating equipment: connecting a compressed air conduit, a transparent hose and a semi-automatic coating device; 4) debugging the coating equipment: starting the semi-automatic coating device, adjusting the pressure of the compressed air and enabling the brazing material to flow out slowly; 5) coating the brazing material: after the brazing material flows out stably, coating a part, which is to be coated with the brazing material, of a workpiece with the brazing material. During coating of the brazing material, the method is uniform and stable in discharging and simple to operate, the production efficiency of vacuum brazing is improved, the problems that the brazing material flows to block holes, the brazing quality is unqualified and the welding repair is conducted again are solved, and remarkable influence on improvement of the vacuum brazing quality is achieved.

Description

technical field [0001] The invention belongs to the technical field of vacuum brazing, and in particular relates to a vacuum brazing semi-automatic brazing material application method and a device thereof, which can improve vacuum brazing production efficiency, control vacuum brazing quality and reduce the scrap rate of parts. Good practical application. Background technique [0002] At present, vacuum brazing is usually applied manually with a small spoon. This method is easy to be affected by human factors, and there are large differences, and the qualified rate of weld quality is low, mainly manifested in the fact that the weld is not full , sunken or not welded, and at the same time, it is easy to flow and block the air film holes of the blade body. After vacuum brazing of high-pressure turbine blades, the first-pass inspection rate is very low, and the plugging rate of brazing material reaches more than 30%, while the rate of out-of-tolerance after repairing holes due ...
