Abstract
Description
Technical Field
[0001] The invention belongs to the field of metallurgy technology, and specifically relates to an energy-saving high-performance powder metallurgy.
Background technique
[0002] The powder metallurgy process mainly consists of three steps. First, the main component material is decomposed into a powder composed of many fine particles; then, the powder is filled into the mold cavity, and a certain pressure is applied to form the desired part shape and The size of the compact; finally, the compact is sintered.
[0003] Because the main material of powder metallurgy is metal powder, and the raw material is decomposed into powder, the raw material needs to be continuously pulverized by the grinder, which causes huge power consumption and noise pollution. During the process of powder filling the mold cavity, a single mold cavity The amount of powder required is the same, but the amount of powder injected into the mold cavity is often abnormal in the mass production ...
Examples
preparation example Construction
[0041] The energy-saving high-performance powder metallurgy preparation method includes the following steps:
[0042] S1: Combine stainless steel powder, yttrium powder, molybdenum powder, zinc oxide, manganous sulfide, aluminum oxide, electrolytic copper, graphite powder, fatty acids, cutting agents, lubricants, strengthening agents, binders, tackifiers, and antiwear agents , The processing aids and regulators are introduced into the mixing barrel and stirred to form a mixed powder. After being evenly stirred, it is filtered through a filter screen. The particles in the mixed powder with a particle size larger than 140-160 mesh are separated and collected, then crushed and then screened. Then pour into each standard dose bucket for use;
[0043] The preparation method of the cutting agent includes the following steps:
[0044] Step 1. Combine cutting oil, tripropyl phosphate, calcium dinonylnaphthalenesulfonate, 2,6-di-tert-butyl p-cresol, dodecenyl succinic acid, triethanolamine b...
