Abstract
A press working apparatus includes: a first positioner that is provided to at least one press of a first press or a second press and that performs positioning of at least one die of the at least one press; and a second positioner that performs positioning of the at least one die and that positions the at least one die in a position deviated in a feeding direction with respect to the first positioner.
Claims4
A press working apparatus of a progressive type that plastically deforms a metal material having a strip-plate shape to form the metal material into a specified shape while feeding the metal material in one direction, the apparatus comprising:
- a first press comprising at least one die that press-forms a first shape in the metal material;
- a second press comprising at least one die that press-forms a second shape in the metal material in which the first shape is formed;
- a first positioner provided to at least one press of the first press or the second press, the first positioner performing positioning of the at least one die of the at least one press;
- and
- a second positioner that performs positioning of the at least one die of the at least one press, the second positioner positioning the at least one die of the at least one press in a position deviated in a feeding direction with respect to the first positioner.
A setting method of a press working apparatus of a progressive type including a first press and a second press, the method comprising:
- operating the first press and measuring an elongation quantity of a metal material;
- determining a target value of a distance in a feeding direction between a die of the first press and a die of the second press based on the elongation quantity measured;
- and
- adjusting an actual distance in the feeding direction between the die of the first press and the die of the second press to the target value of the distance determined.
A maintenance method of a press working apparatus of a progressive type including a first press and a second press, the method comprising:
- operating the first press and measuring an elongation quantity of a metal material;
- determining a target value of a distance in a feeding direction between a die of the first press and a die of the second press based on the elongation quantity measured;
- and
- adjusting an actual distance in the feeding direction between the die of the first press and the die of the second press to the target value of the distance determined.
