steel semi-tubular rivets



Product Description


 


Self-piercing riveting (SPR) is a way of joining sheet materials using a rivet that clinches the sheets as it is pressed into them. Unlike conventional riveting, no hole is required, making it a rapid single-step process.

Typically, the first sheet is pierced when the rivet is inserted. Then, the second sheet is deformed into a button as the rivet is caught within it. The process is similar to clinch joining, however, in clinch joining no rivet is used and a punch deforms the sheets into an interlocking button.

With SPR, the sheets are deformed by a rivet that remains in place and forms the interlock between the sheets. However, SPR requires access to both sides of the joint.

The sheets are first clamped between a die and a blankholder. The rivet is then driven through the sheets using a press tool, piercing the top sheet and causing the lower sheet to expand into the die. The shape of the die causes the rivet and the lower sheet to flare outwards, forming a mechanical interlock.

The rivet head may be finished flush with the top sheet but the bottom sheet will always protrude in a button, which is typically not pierced.

There are several proprietary processes for self-piercing riveting, typically using a semi-tubular rivet, although solid rivets are also sometimes used.

Unlike welding, self-piercing rivets can be used to join dissimilar metals or non-weldable materials.This is becoming increasingly important in the automotive industry where a mixture of aluminum and steel panels are being used. Self-piercing rivets are, therefore, being used instead of spot welding in some vehicle designs.

SPR is an effective way of joining parts made from any combination of aluminum, steel, plastic or composite.

Other advantages include a lack of fumes and sparks, no heating of materials, low noise, and low energy consumption. It’s also suitable for use on pre-coated materials that are unsuitable for welding. Blind rivets, for example, are used for car body assembly where access constraints mean that the joint can only be accessed from a single side. In this case, SPR has zero advantage because access from both sides is required to upset the rivet.
