摘要:
The invention relates to a riveting device (1) and to a method for operating a riveting device (1) for setting blind rivet elements, namely blind rivet nuts and/or blind rivet screws, said device having a mandrel (10), to which a rotational movement can be transmitted for screwing said mandrel into the blind rivet element, and which can be retracted into the riveting device (1) by a tractive movement for at least partial plastic deformation of the blind rivet element. According to the invention, a first motor (11) is provided, with which the rotational movement can be transmitted to the mandrel (10) by way of a first operative connection to the mandrel (10), and a second motor (12) is provided, with which the tractive movement can be transmitted to the mandrel (10) by way of a second operative connection to said mandrel (10).

摘要:
An apparatus according to the invention for connecting metal strips (M1, M2) running successively into a strip treatment installation (A) comprises two cutting punches (4, 5) with in each case a cutting edge (18-20), which is assigned to a cutting edge (18-20) of the other cutting punch (4, 5) respectively. The cutting punches (4, 5) are movable in a cutting movement along a cutting axis (S), in order to introduce a cut into two successive end portions of the metal strips (M1, M2) and establish an undetachable connection in an adjacent region by deformation. In the same position with respect to the cutting axis (S), the cutting edges (18-21) of the cutting punches (4, 5) delimit a cutting gap (22, 23), which extends in the transverse direction (Q) and assumes a gap width (BS) in a width direction (B) aligned at right angles in relation to the transverse direction (Q) and to the cutting axis (S). According to the invention, optimal guidance of the cut is achieved by the cutting edges (18, 20; 19, 21) forming an acute angle (β) with the transverse direction (Q), as seen from the cutting direction (S), and by the cutting punches (4, 5) being adjustable in relation to one another in the transverse direction (Q) of the cutting gap (22, 23) for changing the gap width (BS).
摘要:
The present invention relates to a method for connecting an end of a first metal strip to the beginning of a second metal strip, in particular in strip treatment installations, wherein the end of the strip and the beginning of the strip are positioned one on top of the other to form an overlap and are connected to one another at a number of connecting points in the region of the overlap, characterized in that the connecting points are produced by means of clinching.

Tool assembly and method for forming a workpiece (132) into a housing (136) with a non-round design outer profile (138) at least partially defined by an outer surface (135) at a design position reduced from the initial position thereof. The tool assembly includes a plurality of jaw segments (350), each said jaw segment having an internal surface (356) for engaging the outer surface (135). The jaw segments are movable between a first condition, wherein an opening (360) is defined in which the workpiece is receivable, and a second condition, wherein the internal surfaces of the jaw segments define the design outer profile of the housing. Each internal surface defines a respective portion of the design outer profile. Each internal surface (356) having a preselected end point (364, 366, 368, 370) associated therewith defined by a radius centered on the preselected end point that is substantially coincident with the portion of the design outer profile defined by said internal surface. Each jaw segment is movable along a predetermined path aligned with a preselected end point (364, 366, 368, 370), when moved from the first condition to the second condition, and toward the preselected end point, and when moved from the second condition to the first condition, away from the preselected end point. A motive means (351) is provided for moving said jaw segments between the first condition and second condition.

A crimping assembly is provided for securing a cover part to a structural member. The crimping assembly includes a housing, a drive shaft disposed within the housing and rotatable in a first direction, and a first roller fixedly secured to the drive shaft and rotatable therewith. The crimping assembly also includes a slide shaft disposed within the housing and rotatable in a second direction. A second roller is fixedly secured to the slide shaft and rotatable therewith. A drive mechanism is operably coupled to the drive and slide shafts to roll the first and second rollers over the cover part to secure the cover part to the structural member. A coupling mechanism is operably connected between the drive shaft and the slide shaft to allow movement of the slide shaft towards and away from the drive shaft during operation of the crimping assembly to accommodate variations in flange thickness.
