【The invention's effect】
In the method for manufacturing a crimped assembly according to the first invention, the shaft-shaped portion has a cylindrical shape with a bottom, and an outward flange is provided as a flange portion at an opening of the cylindrical shape with a bottom. The pressed product was used as a crimping part, and was first inserted into the mounting hole of the assembly target from the bottom side of the bottomed cylindrical shape in the insertion step, and then the filler was filled into the bottomed cylindrical shape in the bulge step By compressing in the axial direction in the state, the axial portion is bulged to the outer peripheral side by the action of the filler, and the axial portion is further compressed in the axial direction in the caulking process to perform crimping. The generation of cracks during the crimping process is suppressed, and a good crimped portion can be obtained. Further, since a pressed product having a cylindrical shape with a bottom is used as a caulking component, it is lighter and cheaper than a forged product.
[0014]
In the second invention, prior to the bulging step, a plurality of split dies, each of which has an arc-shaped concave portion corresponding to the outer peripheral shape of the shaft-shaped portion at the tip thereof, are located near the assembly target and have a flange portion. Since it is arranged on the opposite side and the bulging range of the shaft portion is prevented from reaching the mounting object, the mounting object is accompanied by the bulging of the shaft portion in the bulge process. There is no risk of deformation, and good crimping is always performed.

The resulting crimped portion has a relatively smooth surface shape.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
The swaged assembly of the present invention is suitably applied to electric components as in the fourth invention, for example, but can also be applied to assembled products other than electrical components. The object to be assembled and the swaged part do not necessarily have to have conductivity, and the object to be assembled may be made of a material other than a metal material.
[0020]
It is sufficient that the assembly target has at least a substantially plate-shaped assembly portion to which a mounting hole is provided and a caulking component is assembled, and may be integrally provided with portions other than the assembly portion. Generally, the mounting hole is desirably a circular hole corresponding to the outer peripheral shape of the shaft portion, but may be a square hole or the like. The swaged part is a pressed product of a metal plate material having a bottomed cylindrical shaft portion and an outward flange integrally, but may be integrally provided with a portion other than the shaft portion and the outward flange, or may be provided separately. Various modes are possible, for example, the member manufactured in the above may be integrally fixed by welding or the like. It is desirable that the bottomed cylindrical cylinder of the shaft portion is a perfect circle, but an elliptical shape can also be adopted.
[0021]
A caulked part integrally having a bottomed cylindrical shaft portion and an outward flange is manufactured, for example, by subjecting a flat metal plate to drawing or overhanging with a press. Any shape may be used as long as the shaft portion is formed by press working. The bottom of the bottomed cylindrical shape is desirably a hemispherical shape as in the sixth invention, for example, but may be a flat surface substantially perpendicular to the cylindrical portion.
[0022]
In the bulge process, the filling material inside the bottomed cylindrical shape is an incompressible fluid such as water or oil, a gas such as air filled in anticipation of volume change, an elastically deformable synthetic resin such as urethane resin An elastic member with a relatively small change in volume, such as a material, or a granular material that changes to an arbitrary shape as a whole, deforms inward when the bottomed cylindrical shaft is compressed in the axial direction. Any material may be used as long as it prevents the volume from decreasing and swells and deforms to the outer peripheral side.
[0023]
The caulking step is configured, for example, to crush the shaft-like portion substantially flat to form a flat surface parallel to the assembly target, but if the assembly target can be sandwiched between the flange portion, the center is formed. Various modes are possible, for example, the portion may protrude in a convex shape or conversely may be concave in a concave shape.
[0024]
In the caulking process, the filler used in the bulge process is removed to compress the shaft.For example, when a fluid such as oil or water is used as the filler, a fluid passage is provided in a mold used in the bulge process. Alternatively, the caulking process can be performed using a common mold continuously to the bulge process while opening the valve and discharging the fluid.
[0025]
The second invention has, for example, a pair of split molds having a semicircular concave portion having substantially the same curvature as the mounting hole, but may be configured to be divided into three or more. These split dies are disposed, for example, so as to be movable in a direction substantially perpendicular to the shaft portion of the caulking part, and in the bulge process, the recess at the tip is approached so as to substantially surround the shaft portion. In the case of the first invention, there is no need for the split mold if the strength of the assembly target is relatively high and the swelling range of the shaft portion is defined by the assembly target. It is also possible to carry out.
[0026]
The caulking assembly of the third invention is suitably manufactured according to the manufacturing method of the first invention, but other manufacturing methods such as compression without a filler can also be adopted.
