Background
A novel high-voltage contactor product is applied to the field of aviation. Therefore, strict requirements are imposed on the dimensions and performance of the parts. The conductive block is one of the core devices of the high-voltage contactor product, so that the conductive block has critical factors in the aspects of embodying the functions and the performances of the product. The conducting block adopts two kinds of materials of red copper and beryllium bronze to constitute, on the technique of traditional pure red copper conducting block, because the better ductility characteristic of red copper leads to conducting block link torque value to be not enough to satisfy the requirement of novel high voltage contactor product, so adopt beryllium bronze QBe 2's material to make the link, satisfy the new maximum torque value of development needs. Because red copper has good thermal conductivity, pores are easily caused during flame brazing, and the product performance is directly influenced. In the traditional welding technology, the stability and concentricity of two-body welding are poor, and the method is not suitable for the aviation field. In order to solve the above problems, the present invention relates to a design and application of two-body conductive block welding technology.
Disclosure of Invention
The invention aims to solve the technical problems that hydrogen embrittlement phenomenon is generated during welding of two conductive blocks to cause air leakage at the welding position, and meanwhile, the high temperature generated by brazing causes deformation of the conductive blocks, so that the concentricity and the verticality of the two conductive blocks cannot meet the product requirements.
In order to solve the technical problems, the invention adopts the following technical scheme:
a method for welding two conductive blocks comprises the following steps:
the method comprises the following steps: selecting a beryllium bronze material with phi 11, then processing the beryllium bronze material into a thread with the size of M8, selecting a material with enough allowance, and milling a flat material with the size of 1.5 to obtain a connecting end;
step two: selecting a beryllium bronze material with phi 24, and drilling an M8 threaded hole with the depth of 8mm in the center of the beryllium bronze material to obtain a main body of the conductive block;
step three: screwing the connecting end obtained in the first step into the conductive block main body obtained in the second step to obtain a conductive block combination;
step four: drilling an exhaust hole with the diameter of phi 2mm at one end of the conductive block combination obtained in the step three, wherein the drilling depth is 12mm to the neutral size of the connecting end; then brazing is carried out through the welding flux, the welding flux flows in from the milling flat side of the connecting end and is fully fused with the two conductive blocks to form a fixing pin;
step five: and (5) removing connecting end allowance and welding beading by using a lathe for secondary processing, and turning M8 threads.
The beneficial effect of adopting above-mentioned technical scheme is:
1. the invention adopts the modes of anti-loosening and anti-skid double locking and secondary finish machining to solve the problem of complaint, thereby meeting the design requirement of products.
2. The invention effectively solves the problem of hydrogen embrittlement of red copper during brazing, improves the concentricity and stability of the two bodies by at least 5% in the two-body welding technology, and has good reliability in the aviation field because the two bodies are direct factors influencing the product performance and the service life. In addition, on the appearance of the component, welding marks can not be seen after the welding beading is removed, and the component has good smoothness and good performance.
