The structure
of the more complex parts are generally precision casting or investment casting
process. Here zcmim powder metallurgy to introduce the processing methods of
complex parts there.
Part structure
analysis
The analysis of
the components in the processing of parts by important, it analysis the
influence to the parts clamping. Don't underestimate this link clamping. Often
put clip mistakes can make the machining process can not continue down, so that
the parts can not be completed.
1, the basic
types of parts
(1) parts of
the composition of a variety, such as the pros and cons of mating parts, parts
of the surface of the main surface of the parts to be processed parts. First,
we should according to the characteristics of the parts to analyze the
processing route of the parts.
2, parts of the
processing surface
(2) the
selection of parts of the processing surface is very important, often the wrong
choice of the processing surface so that parts can not be installed in the next
step, so that parts processing can not continue.
Two, a brief
introduction of the processing parts of the relevant processes
1, part of the
processing of material selection
Blank data
including all blank manufacturing methods of technical and economic
characteristics of various profiles of varieties and specifications, rough map;
under no blank map, practical understanding of the blank shape, size and
mechanical properties of the. Different material will affect the components and
different material will make the service life of the parts and the production
cost is greatly different, so parts of the material is especially important.
2, to develop
the process route.
3, determine
the machining allowance of each process, calculate the working dimensions and
tolerances.
4, determine
the various processes used in the equipment and tools, fixtures, measuring
tools and auxiliary tools.
5, determine
the time quota.
6, processing
parts.
7, check the
size of the parts.a
