Abstract: Many disadvantages exist  in  the traditional die design method which belongs  to serial pattern.  It is well known  that  heat  treatment  is  highly  important to  the dies.  A new  idea  of  concurrent design for  heat  treatment process  of  die and mould was developed  in order to overcome the existent shortcomings of  heat  treatment process. Heat treatment CAD/CAE was integrated with concurrent circumstance and  the relevant  model was built.  These investigations can remarkably  improve efficiency, reduce  cost and  ensure quality of  R and D for products. Key words:  die design; heat  treatment;  mould Traditional die and mould design, mainly by ex- perience  or  semi-experience,  is  isolated  from manu- facturing process.  Before the design is finalized,  the scheme of  die and mould is usually modified time and again,  thus  some disadvantages  come  into  being, such as long development  period,  high cost and un- certain  practical  effect.  Due  to  strong  desires  for precision, service life,  development period and cost, modern die and mould should be designed and manu- factured perfectly.  Therefore more and more advanced technologies and innovations have been  applied, for ex- ample,  concurrent engineering,  agile  manufacturing, virtual manufacturing, collaborative design,  etc['-''. Heat  treatment of  die and mould is as important as design, manufacture and assembly because  it  has a vital  effect  on manufacture,  assembly and  service life.  Design  and manufacture of  die  and mould have progressed rapidly,  but  heat treatment  lagged seri- ously behind  them.  As  die  and mould  industry  de- velops, heat  treatment  must  ensure  die  and  mould there are  good  state  of  manufacture,  assembly  and wear-resistant properties by  request. 32661 源自$六l维,论:文w网)加7位QQ3249^114 www.lwfree.cn
Impertinent heat  treatment can  influence die and mould manufac- turing such  as  over-hard and-soft  and  assembly. Traditionally  the  heat  treatment  process was  made out according  to the methods and properties brought forward by designer.  This could make  the designers of  die  and  mould  and heat  treatment  perge  from each other,  for the designers of  die and mould could not fully realize heat treatment process and materials properties,  and contrarily  the  designers rarely  un- derstood  the  service  environment and designing thoughtC6'. These  pergences will  impact  the  pro- gress of  die and mould  to a great extent.  According- ly,  if  the process design of  heat  treatment is consid- ered in  the early designing  stage, the aims of  short- ening  development period,  reducing  cost and stabili- zing quality will be  achieved  and  the  sublimation of development  pattern  from  serial  to  concurrent  will be  realized. Concurrent engineering  takes computer integra- tion  system as a carrier,  at the very start subsequent each  stage and  factors have been considered  such as manufacturing, heat  treating,  properties and  so forth  in  order  to  avoid  the  error.  The  concurrent pattern has  dismissed  the  defect  of  serial  pattern, which bring  about  a revolution against serial  pat- tern. In  the present work, the heat  treatment was in- tegrated into  the  concurrent circumstance of  the die .ind mould  development, and  the  systemic and  pro- found  research was performed. progress  of  die  and mould  and  the  market  fore- ground.  Whereas  in  the  concurrent  pattern, the  re- lations among departments are close,  the related  de- partments  all  take part  in  the  development  progress 1  Heat Treatment Under Concurrent Circum- of  die  and  mould  and  have close  intercommunion stance 模具热处理并行设计英文文献和中文翻译:http://www.lwfree.cn/fanyi/20190113/29374.html
