2 Eckold Company figures medium sized company founded in employees in Germany / approx. 200 wold wide Turnover: approx. 15,500,000,00 EUR in 2014 Certified according to DIN EN ISO 9001:2008 and VDA 6.4 Clinchen Stanznieten Umformen Bördeln Falzen Stanzen 2 / ENG-2.6

3 Core techniques Clinching Self piercing riveting Punching Combined punching and embossing Seamclosing Wheelhouse Flanging 3 / ENG-2.6

4 Example Automotive industry applications S-Class BR 221 Clinching for joining of sheets and profiles 658 Eckold-Clinchelements in the complete vehicle. More Eckold-Clinching elements were until then ever not employed in any serial vehicle. Self pierce riveting for joining of sheets and profiles in the tail gate Forming Embossing and punching for assembling of the tail lamps Forming Seamclosing on doors for production of special protection vehicles Forming Wheel house flanging 4 / ENG-2.6

9 Clinching technique 9 / ENG-2.6

10 Clinching technique 10 / ENG-2.6

11 Clinching technique - Advantages Clinching has significant advantages over spot welding: lower total cost of operation longer tool life (approx spots possible) ability to join two different materials, i.e. steel with aluminum Covering different material thicknesses with one set of tooling (Punch and Die) suitable for joining coated sheets no thermal effects on the clinch area no toxic gases or vapours arising no preservative afterwork no additional or ancillary parts no pre-treatment of surface technique compensates for fluctuations in sheet thickness different drives available, i.e. servo, hydraulic and pneumatic-hydraulic electricity or compressed air are the only energy sources required non destructive quality assurance possible 11 / ENG-2.6

12 Self Pierce Riveting 12 / ENG-2.6

13 Self Pierce Riveting - Advantages excellent component accessibility (ram diameter 18mm only) all types of rivets (C-geometrie) from other manufactures can be used in our system different rivet lengths processable joining forces up to 80 kn possible short cycle times low maintenance high process reliability of rivet feeding fixed feeding hose step-by-step mode function frame changing system feeder bow rotateable visualisation check of rivet position possible 13 / ENG-2.6

14 Punching technique 14 / ENG-2.6

15 Punching technique 15 / ENG-2.6

16 Punching technique - Advantages Single and multi layer punching Large quantity of different designs available hand guided units components for the integration in fxtures components for Industrial robot systems complete punching stations Different shapes of holes possible punching of round and form holes notching shearing / cutting Different drives available hydraulic pneumo-hydraulic pneumatic electric 16 / ENG-2.6

17 Embossing and punching technique 17 / ENG-2.6

18 Embossing technique 18 / ENG-2.6

19 Embossing and punching technique - Advantages scrap components (out of tolarance) can be reworked for further use in production High precision Low-maintenance Partial opening strokes are possible Modular design Good power to weight ratio Embossing depth up to 6mm possible Seamless process control Control via axis 7 of the industrial robot possible 19 / ENG-2.6

20 Seamclosing technique Seamclosing fixture / segment Portable seamclosing pliers Seamclosing inserts Auxiliary equipment Hydraulic drive unit 20 / ENG-2.6

21 Seamclosing technique - Advantages Cost reduction (low invest costs) System components like tools and drive units can be used for the next model as well Same quality like big press-tools, cheaper and using much less room and energy Seamclosing of entire Wheelhouse possible Pre-bending and seamclosing is possible in the same fixture by simply changing the upper jaw The flexible concept is the ideal answer for small production runs and spare part supply Minimised space required through integration in existing fixtures Hydraulic unit and Seamclosing pliers can be used in following or other work stations Especially suited for prototype building as well as integration in welding fixtures Eckold seamclosing workstations can be easily poistioned or re-positioned 21 / ENG-2.6

22 Wheelhouse Flanging technique manual handling Handling by industrial robot Handling by Feeding device 22 / ENG-2.6

23 Wheelhouse Flanging technique - Advantages Increasing the wheelhouse clearance for wider tires and snow chains Improvement of roadability and looks by wider wheelbase Optimizing the body stability in the wheel house area 23 / ENG-2.6
