The premise of the flexible multi-point die stamping processing is that each punch can be adjusted to required position. Using numerical control technique, punches can be adjusted by stepping motors through driving screw rods. But each punch requires a stepping motor in this equipment. This kind of equipment is much expensive. In addition, the distance between adjacent punches is much big. Thus, this kind of equipments is not suitable for processing some small and medium-sized sheet metal parts. A new kind of equipment for press forming sheet metal parts is presented. Only two DC motors are needed to adjust punches of male and female moulds in this kind of equipment. Punches can be arranged more closely. This kind of equipments can be used to process small and medium-sized sheet metal parts. |
