About This Product
Self-piercing rivets (SPR) do not require drilling pilot holes in the workpiece in advance, and can be fastened without penetrating the upper workpiece and the lower workpiece. It is possible to join different materials such as aluminum.
■Towards joining of dissimilar materials that contributes to weight reduction
Aluminum + aluminum, aluminum + steel, aluminum + magnesium, steel + steel...
In many manufacturing industries, such as the automobile and electrical industries, there is a trend toward weight reduction, and lighter, higher-strength materials are desired for fastening workpieces. This lightweight material is particularly sought after in the automobile industry, and steel materials are being replaced with aluminum, magnesium, CFRP, etc.
At the same time, the number of joints made of dissimilar materials such as aluminum, magnesium, CFRP, and high-strength steel plates is increasing in the automobile industry, and the number of parts that are difficult to weld is increasing. As an alternative to welding, self-piercing rivets (SPR) are an excellent method for joining two or more dissimilar materials without drilling pilot holes. Additionally, unlike welding, it does not generate heat or gas, so it is an environmentally friendly fastening method.
■Possible to fasten with stable quality under various conditions
Also connects thick plate work and thin plate work, as well as high-tensile steel plates.
In SPR, the rivet itself is pressurized by a tool on a workpiece without a pilot hole, penetrates the upper workpiece, the tip of the rivet opens in the lower workpiece, expands into the shape of a die, and multiple pieces of workpieces are produced. You can conclude the contract. The fastening cross-sectional shape forms an internal lock and secures the workpieces to be fastened together.
■Electric SPR system optimized for fully automatic production lines
Operating speed: max. 200mm/s, fastening speed: max. 100mm/s, max. fastening load 80kN
All data such as driving load, plate thickness, and rivet length before tightening is displayed on the monitor, and if an error is made that does not meet the specified strength, a warning will be displayed. If the thickness of the workpiece or the length of the SPR rivet is outside the controlled values, the system will stop before the SPR rivet is fastened, making it possible to prevent poor fastening.
■Monitor that displays and records conclusion results
Equipped with quality confirmation monitor function
■Rivet protrusion management using unique technology
Zero control of rivet protrusion (Patent: No. 4216505)
From board assembly confirmation to after-sales service
