Folding tab joints.
Clinching tool for sheet metal joining.
Clinching tools for sheet metal from prospot clinching is the mechanical fastening method to join sheet metal without additional components using special tools to plastically form a mechanical interlock between the sheet metals.
Clinching or press joining is a bulk sheet metal forming process aimed at joining thin metal sheet without additional components using special tools to plastically form an interlock between two or more sheets.
By means of rivclinch joining technology steel and stainless steel materials as well as aluminum and other non ferrous materials are joined together in a cost effective and environmentally friendly manner.
The two pieces of sheet metal connected to each other by folding or bending tabs in the form of a buckle and a clamping slot.
Method principle clinching is a method of joining metal sheets or profiles by cold forming the material without joining elements to form a form fitting non positive connection.
Clinching uses cold forming to produce two layer or multilayer joints of metal sheets and or profiles similar to snap fasteners.
How to join multiple sheet metal parts in an economical and reliable way.
Special lengths of 30 mm 40 mm 50 mm 80 mm and 100 mm are possible.
By means of clinching joining technology steel and stainless steel materials as well as aluminium and other non ferrous materials are joined together without welding or fasteners.
Clinching is used in the automotive appliance and electronic industries where it can replace spot welding.
There are many advantages.
Clinch systems joining sheet metal by clinching tools without spot welding nor any fastener or rivet.
Available clinching tool systems tox round joint flanged punch the tox round joint flanged punch is available for joint the diameters 1 5 mm 2 mm 3 mm 4 mm 5 mm 6 mm 8 mm 10 mm 12 mm 14 mm 16 mm 18 mm up to 26 mm.
Depending on the choice of rivclinch joining tools round or square joining points are produced.
In this article we will introduce the 6 types of sheet metal joining process that is often used in product design.
Tox clinching is a simple joining technique that does not require heat or additional elements the clinching process produces a button type positive connection of two or three layers of sheet metal using a cold forming process.
Coated and pre painted metal sheets can also be combined without damaging the surface.
It uses the solid die cavity patented by tox pressotechnik.
The process is generally performed at room temperature but in some special cases the sheets can be pre heated to improve the material ductility and thereby avoid the formation of cracks during the process.
