The invention for working extruded profile sections with respect to the outer contours thereof by way of hot shaping and/or hot stamping and/or cutting operations and/or punching operations comprises the following method steps:inserting the profile sections (1) heated to a temperature in the range of 250 to 450 C. into a two-part shaping tool (2) preheated to a temperature of 300 to 600 C.; andapplying pressure to the shaping tool (2) by way of one or more pressing cylinders (3) of a press (4). The device for carrying out the method comprises a press (4) and a shaping tool, wherein the shaping tool (2) is formed of two tool halves I, II, which are displaceable with respect to each other, and between which the profile section (1) is inserted.

A joined sheet stack and a method and system for forming the stack are disclosed. The stack may include a steel sheet and a second sheet. The steel sheet may include a bulk portion having a first tensile strength and one or more fastener regions having a second tensile strength that is lower than the first tensile strength and a microstructure that includes tempered martensite. A fastener may extend through each fastener region joining the steel sheet to the second sheet. The method may include heat treating one or more regions of a steel sheet to form one or more fastener regions having a tensile strength that is lower than a bulk tensile strength of the steel sheet and a microstructure that includes tempered martensite. A fastener may then be inserted into the one or more fastener regions to join the steel sheet to a second sheet.

An apparatus and method for operating a staking assembly includes a housing defining a machining passage having a longitudinal axis, an actuator rod disposed for axial movement along the longitudinal axis in the machining passage, having a first end configured to connect to a linear-reciprocating source of movement and a second end having a tool configured to deform a boss, and an air source configured to selectively provide a source of heated air.

A jaw assembly for a rivet setting tool the jaw assembly including a plurality of jaws each jaw defining part of an interlocking mechanism and an oppositely located part of another interlocking mechanism wherein adjacent jaws interlock via engagement of the parts of the interlocking mechanisms of the respective jaws for enabling radial movement of the jaws relative to each other while restricting axial movement of the jaws relative to each other.
