Sheet Metal Processing Connection Technology Section 1: TOX Riveting 1. Definition: The connected part is pressed into the die through a simple punch. Under further pressure, the material in the die \"flows\" outward. The result is a round connection point without edges and burrs, and it will not affect its corrosion resistance. Even for panels with plating or paint on the surface, the original anti-rust and anti-corrosion properties can be retained because the plating and paint layers also deform and flow together. The material is squeezed to both sides and squeezed into the panel on the side of the die, thus forming a TOX connection point. As shown in the figure below: [pic] 2. Connection method: It can complete the connection of two or more layers of panels of the same or different materials, and the thickness of the panels can be the same or different. Under the same conditions, the static connection strength of a single TOX point is 50%-~70% of that of spot welding, and the double point is the same as spot welding. 3. Connection range of different connection points: (unit: mm) | Connection point diameter | 12 | 10 | 8 | 6 | 5 | 4 | 3 | | Connection material thickness range | 4 ~ 11 | 1.75 ~ 7 | 1.6 ~ 6. | 1.0 ~ 3. | 0.9 ~ 2. | 0.6 ~ 2. | 0.5 ~ 1. | | | 0 | 0 | 5 | 0 | 5 | | TOX midpoint to edge minimum distance | 10 | 8 | 7 | 6 | 6 | 5 | 4 | | | | | | Note: TOX connection diameter is closely related to connection strength. The larger the diameter, the greater the connection strength. 4. Disadvantages of TOX riveting: 1) Depends on positioning jig or die block for positioning. (2) The minimum width of the connection material is affected by the TOX die…
