In the hardware structure is more complex
parts are generally precision casting or investment casting process. There are
MIM process to manufacture, the complex parts of the processing method?
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.
