Embodiment Construction

[0019] The casting method of a kind of industrial robot manipulator of the present invention comprises the following steps:

[0020] A) charge smelting: putting 50-70% of pig iron by mass percentage, 25-40% of returned charges and 5-20% of steel scrap into an electric furnace for smelting to obtain the original molten iron, then filtering out the slag on the surface of the original molten iron, Sampling and testing raw molten iron;

[0021] B) Spheroidizing treatment and inoculation treatment of raw molten iron: use an electric furnace to preheat the nodulizer, inoculant and slagging agent, and then add the preheated nodulizer, inoculant and slag collecting agent to the spheroidizing Inside the bag, put the spheroidizing agent at the bottom of the spheroidizing bag first, then spread one-third of the inoculant on the nodulizing agent, and finally cover with slag accumulator, perlite and iron plate The two primary molten irons are poured into the nodularization ladle for spher...

Abstract

The invention discloses a casting method of an industrial robot mechanical arm. The method comprises the following steps of furnace burden smelting, spheroidizing and inoculation treatment of base iron, spheroidizing quality detection and pouring. Compared with the prior art, the casting method has the advantages that the structure is simple, the design is reasonable, and the mechanical arm obtained by casting is good in mechanical property, high in fatigue resistance, accurate in size, clean in inner cavity, free of burnt-on sand or flashing, and capable of meeting the use requirements of actual work.

Description

【Technical field】 [0001] The invention relates to the technical field of casting methods, in particular to a casting method for a mechanical arm of an industrial robot. 【Background technique】 [0002] The localization of core components of industrial robots affects the industrial structure and has far-reaching significance. As an irreplaceable important equipment and means in advanced manufacturing, industrial robots have become an important symbol to measure a country's manufacturing level and technological level. At present, my country is in an important period of accelerating transformation and upgrading. The robot industry with industrial robots as the main body is an important path choice to solve the problems of rising industrial costs and environmental constraints in our country. China's industrial robot market has continued to perform strongly in recent years, and the market capacity has continued to expand. [0003] In practical application, the robot arm needs to...
