Abstract

A power cable clamp is characterized in that raw material powder for manufacturing the power cable clamp comprises components in parts by mole as follows: 120-130 parts of Fe powder, 5-6 parts of Cu powder, 3-4 parts of Zn powder, 1-2 parts of SiC, 1-2 parts of Mn powder, 0.8-0.9 parts of TiB2, 0.6-0.7 parts of Cr powder, 0.4-0.5 parts of Cr3C2, 0.4-0.5 parts of V powder, 0.2-0.3 parts of Y2O3 and 0.1-0.2 parts of CeO2. Stepped annealing is performed after sintering, so that a material microstructure is homogenized, and the surface hardness and strength as well as oxidation resistance of a workpiece are improved with a nitriding procedure and a boriding procedure.

Description

technical field [0001] The invention relates to a power cable clamp, which belongs to the technical field of power cables. Background technique [0002] At present, cable clamps are widely used in the pipelines of engines and electronic system circuits in the aviation and aerospace industries, and they play a role in fastening and fixing the pipelines and circuits. In these industries, there are high requirements for product performance, and high requirements for product material, strength, structure, weight and other performances, which cannot be replaced by other products. When ordinary products are used in these industries, the bending part of the clamp cannot withstand the vibration of the aircraft, so that the cables and the like escape from the clamp, and there is even the possibility of breaking the bending part, and in some special environments, Products with general performance cannot meet its requirements. Contents of the invention [0003] A power cable clamp,...
