20140216123 | DIE CONDITION DETECTION | 08-07-2014 |
20130336745 | SELF-PIERCING RIVET - A self -piercing rivet ( | 12-19-2013 |
20130227832 | FASTENING METHOD AND APPARATUS - A fastening method and apparatus ( | 09-05-2013 |
20130223956 | FASTENER DELIVERY APPARATUS - A fastener delivery apparatus includes a nose assembly to releasably hold a fastener. The nose assembly includes a plurality of balls or rollers and associated biasing members to provide a biasing force which biases the balls or rollers such that they engage with the fastener. Each biasing member exerts force in a first direction and an associated ball or roller moves in a second direction which is different from the first direction. A force transfer surface is provided between the ball or roller and the biasing member, the force transfer surface acting to convert at least a component of the force exerted by the biasing member in the first direction into force exerted on the balls or rollers in the second direction. | 08-29-2013 |
20130205574 | RIVETING METHOD AND APPARATUS - A method of riveting comprising using a punch ( | 08-15-2013 |
20120227256 | FASTENER DISPENSING APPARATUS - A fastener dispensing apparatus includes a body that defines a punch path and at least partially surrounds a punch that includes forward and rearward portions. The punch reciprocates between retracted and advanced positions in which the tip of the forward portion extends from an end of the punch path to drive a fastener towards the workpiece. A fastener feed path extends transverse to the punch path and is defined by a surface of the body, the fastener feed path receives an elongate carrier of fasteners. A fastener feeding device sequentially feeds fasteners along the fastener feed path and into alignment with the end of the punch path. An actuator is drivable by the reciprocal movement of the rearward portion of the punch. An engagement member engages the carrier and is moveable relative to the body. | 09-13-2012 |
20120090158 | SELF-PIERCING RIVETING - A method for forming a joint using a self-piercing rivet includes the steps of: positioning the sheet material over a die and providing a rivet having a substantially cylindrical shank and a head, the shank having a central blind bore and an annular piercing end spaced from said head. The ratio of the difference between the outside and inside diameters of the shank in the region around the bore to the outside diameter of the shank is in the range 0.47 to 0.52. The method also includes positioning a rivet over the sheet material at a position opposite the die and using a punch to set the rivet and force it into the sheet material such that it pierces the upper surface thereof and such that the shank deforms outwardly to interlock with the material but without penetration to the die side of the material. | 04-19-2012 |
20120060338 | SELF-PIERCING RIVETING - A self-piercing rivet includes a substantially cylindrical shank having an outside diameter and a head. The shank has a central blind bore that defines an inside diameter and an annular piercing end spaced from said head. The ratio of the difference between the outside and inside diameters of the shank in the region around the bore to the outside diameter of the shank is in the range 0.47 to 0.52. | 03-15-2012 |

20090116934 | SELF-PIERCING RIVETING - A self-piercing rivet for forming joints in high strength steel has a partially hollow shank of a particular form in order to ensure that it has sufficient column strength to pierce the material. The thickness of the shank is such that adequate joint strength is achieved with a lower degree of flare than would be necessary for conventional riveted joints. The ratio of the thickness of the shank (outside diameter minus inside diameter) is in the range 0.47 to 0.52. The ratio of the cross sectional area of the shank in the region around the bore to the outside diameter of the shank is in the range 3.0:1 to 3.6:1 | 05-07-2009 |
