Fig. 1 is internal withdraw type semi-hollow self-pierce riveting rivet sectional view;
Fig. 2 follows closely bar pin A place partial enlarged drawing in Fig. 1;
Fig. 3 is die sectional view;
Fig. 4 be internal withdraw type semi-hollow self-pierce riveting rivet, die and be connected plate riveted after sectional view.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figures 1 to 4, a kind of internal withdraw type semi-hollow self-pierce riveting riveting device, has an internal withdraw type semi-hollow self-pierce riveting rivet 20, die 21 for internal withdraw type semi-hollow self-pierce riveting rivet.
As Fig. 1, shown in 2, rivet comprises the head of a nail 1 and has the nail bar 2 of centre bore, and the head of a nail 1 and nail bar 2 are integral type structure and have common central axis.
Nail bar 2 lower inner surface is provided with straight line A6, arc-shaped edges A8 and straight line B10 from top to bottom successively, and arc-shaped edges A8 two ends are connected with straight line A6 and straight line B10 transition respectively.Nail bar 2 lower external face is provided with straight line C7, arc-shaped edges B9 and straight line D11 from top to bottom successively, and arc-shaped edges B9 two ends are connected with straight line C7 and straight line D11 transition respectively.
Straight line B10 is connected by arc section 12 with straight line D11 lower limb root place, makes nail pole-footing portion form the basil.
The height of rivet vertical direction and straight line A6 are between 0.4 ~ 0.45 to the horizontal range ratio of rivet center axis of symmetry, and the present embodiment is 0.43.The ratio of arc section 12 center of circle and straight line horizontal range and nail bar 2 wall thickness A is between 0.26 ~ 0.36.The vertical direction angle in straight line B10 and excessively arc section 12 center of circle is 25 ° ~ 35 °.The vertical direction angle in straight line C11 and excessively arc section 12 center of circle is 38 ° ~ 45 °.The radius of arc section 12 is 0.02mm ~ 2mm.The present embodiment is for being 0.03mm.So easy increase concentrated stress, is beneficial to and thrusts plate.The dome 3 of the centre bore of nail bar 2 is planar shaped, and surrounding has chamfering 4.
