| titleOfInvention | A kind of method, mould and system of manufacturing machine part |
| abstract | The invention discloses a kind of method, mould and system of manufacturing machine part, adopt drop stamping technique manufacturing machine part, described method comprises: under default heating-up temperature, heat blank steel plate; Described blank steel plate is put into the mould punching of described machine components, so that described blank steel plate forms fold and form described machine components in described mould at the fillet place of described mould; The mould of described machine components comprises die and punch, has the punching press space that holds described blank steel plate between described die and punch, and the punching press gap length at the fillet place of described mould is greater than the thickness of described fold. By technical scheme of the present invention, can prevent from continuing when punching press at fold place by drawing crack because fold irregular stacking causes steel plate, thereby can reduce in production by the product quantity of drawing crack, thereby can reduce the percent defective of product, and then reduce production costs, save the consumption to iron and steel resource. |
