Abstract
Disclosed is a compact roller hemming device capable of performing a hemming process with respect to various works. Specifically disclosed is a roller hemming device for hemming a work, which includes rotary shafts rotating on axes thereof, and lower dies and lower dies on which the corresponding work is placed. The lower dies and the lower dies are arranged on outer circumferential parts of the rotary shafts at predetermined intervals. The rotary shafts rotate so that one each of the lower dies and the lower dies is selected depending on a type of the work to be hemmed.
Claims4
A roller hemming device for hemming various works each having a plurality of parts to be hemmed, a work comprising:
- a pair of die changing devices for performing die-change depending on a type of the work,
- wherein the pair of die changing devices is configured to move into and out of proximity with each other,
- each of the pair of die changing devices comprises:
- a rotary shaft rotating on an axis thereof;
- and
- a plurality of lower dies each of which the corresponding one of the various works is placed on,
- wherein each of the plurality of lower dies is formed according to a shape of the corresponding part to be hemmed of the work,
- the plurality of lower dies are arranged on an outer circumferential part of the rotary shaft at predetermined intervals, and
- the rotary shaft rotates so that one of the plurality of lower dies is selected depending on a type of the work to be hemmed,
- the selected lower die of said one die changing device and the selected lower die of the other die changing device are so arranged in accordance with the two parts to be hemmed of the work which are opposed to each other that the two parts to be hemmed of the work are hemmed in a same step.
A roller hemming device for hemming various works each having a plurality of parts to be hemmed, comprising:
- a rotary shaft rotating on an axis thereof;
- and
- a plurality of lower dies each of which the corresponding one of the various works is placed on,
- wherein each of the plurality of lower dies is formed in a shape corresponding to all parts to be hemmed of the corresponding work so as to come in contact with all the parts to be hemmed thereof,
- the plurality of lower dies are arranged on an outer circumferential part of the rotary shaft at predetermined intervals,
- the rotary shaft rotates so that one of the plurality of lower dies is selected depending on a type of the work to be hemmed, and
- all the parts to be hemmed of the work corresponding to the selected lower die are hemmed on the selected lower die in a same step.
