Abstract
A compact roller hemming device which can perform a hemming process with respect to various works. The roller hemming device for hemming a work includes rotary shafts rotating on axes thereof, and first lower dies and second lower dies on which the corresponding work is placed. The first lower dies and the second 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 first lower dies and the second 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, on each of which the corresponding one of the various works is placed,
- wherein each of the plurality of lower dies is formed according to a shape of the corresponding part of the work to be hemmed,
- 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
- the selected lower die of said one die changing device and the selected lower die of the other die changing device are arranged in accordance with the two parts of the work to be hemmed which are opposed to each other so that the two parts of the work to be hemmed 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, on each of which the corresponding one of the various works is placed,
- wherein each of the plurality of lower dies is formed according to a shape of the corresponding work so as to come in contact with all the parts of the corresponding work to be hemmed,
- 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 of the work to be hemmed corresponding to the selected lower die are hemmed on the selected lower die in a same step.
