Claims (11)

As described in detail in the drawings and the text, the two fasteners for fastening the work pieces of various thicknesses from the determinable minimum thickness to the maximum thickness together and fastening them into a plurality of work pieces, include the head and the recessed member. It is made of a provided pin member, and is provided with a plurality of grooves on the upper surface of the recessed part, and the tubular member is swung into the grooves on the recessed portion of the pin member by means of a tool device equipped with an anvil that is bent into a swage. It is applied to bend with the tubular member, and the creep device is applied to the clamping area of the recessed part, and the tool is feasible to apply a relative axial tension between the pin member and the tubular member. The swage is bent into the groove located on the recessed portion of the pin member. Eventually, the predetermined number of grooves is substantially the same annular combination lock and steeply inclined grooves, and the predetermined number of each of the novel grooves is divided by inner walls branched outward from the first and second radiation. The first inner wall is located closer to the head side than the second inner wall, and is formed at an inclined angle as a radiation type plate, and is much larger than the angle formed by the side wall. In extending through the cross-section of the joining portion, there is a junction point of the branched sidewalls (20, 22), each of which is divided by a concave radial member (24; 124) in the groove, and the first and second sidewalls The number of grooves (18, 118) that are determined in advance by connecting the inner end of the radiant type of the pipe from the inside includes the groove installed by approaching the outer end of the tubular member, and the material of the tubular member is swaged on the recessed part. And the first and second sidewalls 20 and 22 described above prepare a relative axial force between the sidewalls in the final restricted groove, thereby forming an edge, and the force therein By being swaged to bend, it is deformed as a material of the tubular member. The relative axial force will be added to the relative axial tension as the relative axial force, and the concave member applied by the tool will be crushed in the final restricted groove described above, the convex radial portion has a radial curvature, and a predetermined stress Fragmentation is promoted in the last mentioned groove by providing concentration, corresponding to the combination of the relative axial force and the relative axial tension described above, and any one of the predetermined number of grooves is the last mentioned groove. A fastener for assembling a work piece, which is characterized by its own function by being installed. In the fastener according to claim 1, the convex radius portion has a minimum radius with respect to the diameter of the pin member in a ratio of about 1:50. In the fastener according to claim 2, the convex radius portion is for assembling a workpiece characterized in that it has a radius for the plate diameter in the range of about 1:50 to about 2:50. Fasteners. A fastener for assembling a work piece characterized in a convex radius portion having a maximum radius for a pin diameter within a range of approximately 2:50 in the fastener in the entire claims. In the fasteners in the above claims, the pin member has a predetermined hardness lower than that of the pin member 12; 112, and for this reason, the annular member has a hardness in the range of approximately 45R _B to 65R _B , and the pin A fastener for assembling a work piece characterized by the fact that crushing is easy to occur in the groove by controlling the outflow of swage bending material, which is a tubular member, and has a hardness in the range of approximately 15R _c to 25R _C. A portion of the recessed portion 200 installed in the opposite direction from the top and the end having one plurality of grooves 202 designed to be deformed and pinched with a predetermined number of grooves in the fastener of the entire claims A fastener for assembling a work piece characterized by a pin that is pinched by holding the withdrawal device in. In the fastener of claim 6, a clamping device that substantially combines the upper grooves 202 for a workpiece within the clamping range once and practically cut within the grooves 118 for a workpiece within the clamping range. The tubular member, which is once swaged, is a fastener for assembling a work piece characterized by a predetermined number of grooves 118 that provide a predetermined gripping range that is a determinable minimum to a determinable maximum. In the fastener of claim 7, it is possible to give the maximum range of clamping selected to be slightly isolated from the joining point of the swage bending anvil having a tubular member to start the assembling, and a clamping device in which a plurality of jaws is formed. Fastener for assembling a work piece, characterized in that. A fastener for assembling a workpiece according to claim 8, characterized by another groove extending approximately equal to the sum of the maximum allowable clamping range value plus the effective length of the jaw. In the fastener of claim 8, a work piece characterized by different grooves extending approximately equal to the total length equal to the effective length of the jaw plus the maximum squeeze allowance not to exceed the diameter of the suction site. Fasteners for assembly. In the entire scope of the above claims, the minimum minimum thickness to a point approximately equal to the length of the tubular member extending beyond the work piece plus the distance from the joint point of the swaged anvil with the tubular member for starting engagement. A fastener for assembling a work piece characterized by a predetermined groove member extending from the same point as the suction part. ※Reference: Disclosed according to the content of the initial application.
