10 / 31.03.15 ENG-2.6

Clinching technique

11 / 31.03.15 ENG-2.6

Clinching technique - Advantages

Clinching has significant advantages over spot welding:

lower total cost of operation

longer tool life (approx. 250.000 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

12 / 31.03.15 ENG-2.6

Self Pierce Riveting

13 / 31.03.15 ENG-2.6

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

Embossing and punching technique

18 / 31.03.15 ENG-2.6

Embossing technique

19 / 31.03.15 ENG-2.6

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

Seamclosing technique

21 / 31.03.15 ENG-2.6

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

22 / 31.03.15 ENG-2.6

Handling by industrial robot

manual handling

Handling by Feeding device

Wheelhouse Flanging technique

23 / 31.03.15 ENG-2.6

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
