Abstract：
|
|
Through a specific example,it not only described laser-hardening technology for solving deep drawing mould blank-holder hamstring problem,but also through the mould material and heat treatment options,laser hardening,changing the traditional manufacturing technology of mould blank-holder were carried out. The deep discussion about the processing means,methods,and material selection,etc.was done. Laser hardening characteristics were also expounded. Drawing mould obviously improved the service life and reduced waste after adopting the laser technology to enhance surface hardening. Several sets of mould verification conclusion shows that laser hardening technology applicationin mould has a wide prospect.
