たすことがある。 In order to manufacture such a bush, it is necessary to
The anti-vibration rubber bushing crimping device shown in Japanese Patent No. 203242 is used. This conventional caulking device has a third caulking device.
As shown in the figure, the outer shape is formed into a truncated cone shape, has a through hole 2 in the center that is concentric with the outer diameter, and is divided into multiple pieces by planes parallel to the center line on rays at equal angular intervals from the center line. The die 1 is inserted into a die holder 5 having a conical hole with the same taper as the outer diameter of the die formed on its inner surface, with a spring 12 interposed between the split surfaces. By moving this die 1 to the small diameter side of the die holder 5 and reducing the diameter of the through hole 2, the diameter of the outer cylindrical metal fitting of the bush inserted into the through hole 2 is reduced. Move to the large diameter side of the conical hole and insert die 1.
When expanding the diameter of the through hole 2, the dividing surface of the die 1 may not open evenly due to uneven repulsive force of the spring 12 or friction with the die 1, and the diameter of the die 1 may not be expanded sufficiently. This may cause trouble when inserting the outer cylindrical metal fitting into the through hole 2 of the die 1 using an automatic feeding device.
