Lubrication
15
Roller lubricator
Our traditional contact lubricators are valuable
for full size or sectorial appli-cating of
blanks, coils and profiles.
Different types of rollers (Felt, Brush, Cellpor)
for different applications, speeds and
lubricants.
Wide range of standard devices - from 15 mm
mini roller to 2000 mm sector lubricator.-
from motor driven roller to mobile blank
lubricator.

Benefit by us of tape

• Lubrification

Combination of the right oil /grease with
protection tape gives excellent results.
Only oil

Problem Waste treatment Time for preparation
Scrap/ production defaults
Advantage tape Less processing oil. Easier
handling Higher yield/Less polishing

Different types of tape

• SPV 224P SPV 225P PVC tapes
• 30804 308LA5 3104H5 Rubber based PE
• 9205 6065E5 Easy peel acrylic based
• 3100H5 Laserguard

Part II Electronic ShimmingComputerized
control of blankholding forcefor deep drawing of
extreme components

• New patented technology

25
Traditional shimming (what shimming used to be)

• Manual shimming with metal foil

26
What our customers wanted

• Optimized blank hold control during deep draw
• Improved product quality
• Scrap reduction!
• Increased productivity
• Deeper draws without annealing
• Flexibility many tools on the same press
• Shimming tools that work with existing dies
• Shimming tools that can be fitted to existing
  presses

27
Why is Shimming needed?

• The press frame and the die are deflected during
  deep draw
• The blank thickness is changing during deep draw

28
Electronic Shimming How it works

• The Electronic Shimming Plate allows precise
  compensation for
• die deformation
• change in blank thickness

29
How it works

• The Electronic Shimming Plate is placed directly
  under the blankholder

Products created with Electronic Shimming
33
Extreme blank hold control

• The Electronic Shimming Plate offers flexibility
  and adaptabilityfor a range of deep draw
  operations

34
Control Unit

• Advanced Control Unit allows
• real-time monitoring
• adjustments on-the-fly
• quick tool changes

35
A complete solution
36
Shimming plates can be designed for many purposes
37
Forming of future products can be simulated

• Simulation results

38
and tools can be perfected to meet requirements

• Finished product

39
Summary, benefits

• Better Products
• No wrinkles or buckles and less tension in the
  final product
• Allows up to 12 deep draw, without annealing
• Increased Productivity
• Short start-up time
• Extreme blank hold control
• 50 scrap reduction
• Reduced wear on active tool plates
• Cost efficiency
• Adapts to existing dies and presses
• Payback time typically 3-6 months
