Reduce tooling costs, Increase production rates, & Improve Part Quality

Controllable Gas Springs (KF2) are a relatively inexpensive way to increase forming control and reduce the number of dies needed to produce a part, therefore reducing the timeto produce the part & saving on tooling costs.

The ability to control the gas spring force on the return stroke has many advantages; here are just a few examples:

 

Example #1: Dual Step Forming
Drawing Operation

  • Combines two forming operations into one tool- which saves on tooling expenses & increases production rate
  • Increase forming control which can improve quality
  • Prevents part from turning in on itself when press ram returns
  • Function within the tool, not the press
  • Single action press instead of double action press

 

Example #2: Improve Part Quality
Baby Blank Holder

  • Blank holder force that is too high for a given area of the panel, will prevent the material flowing into the die correctly & leads to thinning of the panel and splitting
  • Blank holder force that is too low for a given area, will allow too much material to flow into the die, resulting in the panel wrinkling or buckling
  • The baby blank holder is controlled by a KF2 gas spring whose force can be remotely adjusted via a Control Block. TheKF2 provides just the right amount of pressure pad force on the forming stroke, on bottom dead center the KF2 will lock resulting in NO force on the panel as the die opens

Why use Controllable Gas Springs (KF2)?
As shown in the two examples that use Controllable Gas Springs (KF2), you can optimize your operation by increasing production rates, reducing tooling costs, & improving part quality. You can also rely on KALLER’s high-quality products that won’t unexpectedly break down, minimizing the risk of production stops.
