Description
Technical field
The utility model is applicable to a kind of sheet member, curved sheets part of surface irregularity, the riveted joint workpiece of plate as thin as a wafer, is a kind of Novel pressure Riveted screw pole specifically.
Technical background
Current five metals riveting method is very common, because riveted joint has lot of advantages with respect to welding and bonding, riveted joint adopts metal riveting part, for bonding, low to temperature susceplibility; For welding, low to manufacturing process and the requirement of personnel's degree of being skilled in technique, riveted structure stability is better.As shown in Figure 4, the working principle of riveted joint is the plastic deformation by riveting parts, and material is made to the shape that we need, and reaches rigidly connected effect.Riveted joint has according to technique classification: press, revolve riveting, the mode such as the riveting of rising, staking.
The existing riveting parts that presses, " riveting nut " and the patent No. that as the patent No., are " 200920314381.5 " are: " a kind of locking self-clinching stud " of " 201320373728.X ", in use, there is following shortcoming in this self-clinching nut: first, its locating face is the step plane of riveted joint outer rim, and pressing in process of the sheet member of surface irregularity, curved sheets part, step plane of its riveted joint head is a plane, locate inaccurately, and easily occur rotating.The second, it rivets outside nicking structure for radially direct male type structure, and nicking and cylinder itself is without transition, and in the moulding bending deformation process pressing, the ductility of nicking itself is bad, does not reach the long-pending object of extended surface to greatest extent.So can not be applicable to thinner plate riveted joint.The 3rd, riveting parts inwall is crooked in stamping process, and as shown in Figure 1, place, inflection point stress is concentrated, and easily occurs slight crack, causes riveting parts fracture.
So now lack a kind of sheet member, curved sheets part of surface irregularity, the Novel pressure Riveted screw pole of plate as thin as a wafer, meet the development in pluralism of riveting process.
