A method for forming a joint in at least one high strength sheet steel having a UTS in the range 200 to 1400 MPa 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.
A die is supported in a die holder such as a frame or an adapter supported in a frame such that it is operational use in a material deforming operation. One or both of the die and the die holder have at least one gas passage which is substantially closed by at least part of the die. Gas such as pressurized air is directed into an end of the gas passage opposite the die via a hose connected to a gas source. If the die is broken or loose leak paths are available for the escape of gas past the die to or from atmosphere. A pressure sensor connected to the hose detects the change in pressure of the gas and the magnitude of that pressure is used to determine the die condition. Alternatively a flow rate sensor is used to detect a change in the flow rate of the gas in order to determine the condition of the die.

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.

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.
Fasteners, such as rivets, are fed to a fastener insertion tool (1) via a buffer magazine (5) adjacent to the tool. The buffer is movable with the tool and C-frame between an operative position where fasteners can be inserted int a workpiece and a re-filling position where it is docked at a docking station (13) to reload. Fasteners are delivered to the docking station from a source (14) and held there ready for when the tool docks. Once docked a transfer gat is opened at an interface between the buffer magazine (15) and the docking station (13) and fasteners from the docking station are transferred into the buffer magazine. A fastener insertion cycle is executed while the docking station is refilled with fasteners. A control cycle is used to control the quantity of fasteners loaded into a storage track at the docking station and operates to reduce overfilling of the buffer.

A joint is produced in at least two overlapping workpieces using a joining tool including a punch reciprocally disposed in a cylinder. The workpieces are disposed between the tool and a die. The tool applies a compressive force to deform the workpieces into a joint at a joining area between the tool and die. Continuous ultrasonic energy is applied to at least one of the workpieces in the joining area for at least part of the time during production of the joint to increase the ductility of at least one of the workpieces in the joining area. This induces an acousto-plastic effect in the material being formed which temporarily reduces its strength so as to exhibit increased ductility. The joining method may be used in self-piercing riveting and clinching techniques and enables viable joints to be formed in high strength materials or thick sheets of material.
A die (13, 213, 313) is supported in a die holder (381) such as a frame or an adapter (18, 518) supported in a frame such that it is operational use in a material deforming operation. One or both of the die and the die holder have at least one gas passage which is substantially closed by at least part of the die. Gas such as pressurized air is directed into an end of the gas passage opposite the die via a hose (42, 542) connected to a gas source. If the die is broken or loose leak paths are available for the escape of gas past the die to or from atmosphere. A pressure sensor (41) connected to the hose detects the change in pressure of the gas and the magnitude of that pressure is used to determine the die condition. Alternatively a flow rate sensor is used to detect a change in the flow rate of the gas in order to determine the condition of the die.

Fasteners, such as rivets (60), are fed to a fastener insertion tool (1) via a buffer magazine (5) adjacent to the tool. The buffer is movable with the tool and C-frame (6) between an operative position where fasteners can be inserted into a workpiece and a re-filling position where it is docked at a docking station (13) to reload. Fasteners are delivered to the docking station from a source (14) and held there ready for when the tool docks. Once docked a transfer gate (25, 28) is opened at an interface between the buffer magazine and the docking station and fasteners from the docking station are transferred into the buffer magazine. The quantity of fasteners in the buffer magazine is detected and the last fastener is retained so as to support preceding fasteners loaded into the buffer magazine. Any subsequently loaded fasteners back to the docking station either under gravity, under the influence of a pressurized gas or both. The gate is then closed and the insertion apparatus separates from the docking station.
A method for joining elements together, the method comprising the steps of: positioning the elements relative to one another; enhancing the formability of at least a portion of at least one of the elements using a laser; and joining the elements together using a mechanical fastening method.
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.
