(1) The designed shield must meet the product use and technical performance, and can be easily assembled and repaired.
(2) The designed shield must be used to improve the utilization of metal materials, reduce the variety and specifications of materials, and minimize the consumption of materials. Use low-cost materials wherever possible, and make parts as free as possible and with less waste.
(3) The designed motor shrapnel must have a simple shape and a reasonable structure to facilitate the simplification of the mold structure and simplify the number of processes, that is, to complete the machining of the entire part with the least and simplest stamping process, reduce the processing by other methods, and facilitate the stamping operation. It is easy to organize mechanization and automated production to improve labor productivity.
(4) Designed shields, under the condition of ensuring normal use, try to make the dimensional accuracy grade and surface roughness grade requirements lower, and facilitate product interchange, reduce waste and ensure product quality stability.
(5) The designed shield should be used to process the existing equipment, process equipment and process as much as possible, and to facilitate the extension of the service life of the die.
