Definitions
- the invention relates to a product made from sheet metal, a method for forming a product made of sheet metal and a method for joining products made of sheet metal together.
- the invention finds particular but not exclusive application in joining building elements and/or building components formed of sheet steel together and, for instance, has use in the fabrication and/or erection of metal framed buildings, wall frames and partitions, roof trusses, and metal panels and sheets.
- the wall frames of such structures typically comprise spaced apart upright studs extending between horizontal roof and floor structural members, and substantially horizontal noggings disposed between adjacent ones of the studs.
- the wall frames support metal roof trusses forming the roof structure of the building or dwelling, and the studs, Hoggings and trusses are often fabricated by roll-forming steel strip.
- Buildings of this type are commonly roofed and cladded with metal panels and sheets having a ribbed cross-section providing structural support to the panels and sheets.
- the metal panels and sheets are typically fastened to the wall studs and roof trusses by self-tapping screws.
- Clinch joints have been used in the past to fasten overlapping metal sheets and in the fabrication of frame elements for use in the construction of the frame of such buildings and dwellings.
- the clinches are formed by a co-operating male punch and female die, the punch plasticly deforming the sheet metal forward of the punch into the die cavity and laterally swaging the displaced metal such that mechanical inter-engagement of the overlapping metal sheets is effected thereby holding the sheets together.
- Various clinching apparatus with co-operating punches and dies are known in the art including apparatus which utilise a rotary punch and die set. Such clinching apparatus arc adapted to form a row of spaced apart clinches along the overlapping metal sheets.
- the clinches are formed by driving the clinching tool along the metal sheets or by feeding the sheets between the rotary punch and die set.
- An example of a clinching apparatus is described in International Patent Application No. PCT/AU91/00120, The formation of the clinches in the required location requires careful alignment of both the clinching apparatus and the overlapping sheet metal work pieces, and support of the work pieces during the clinching process. This is particularly the case when a row of clinches along the overlapping metal sheets is formed.
