A Simple Out Feed Solution for Progressive Stamping

Applications where sensor contact is unavoidable are some of the most challenging to solve. Metal forming processes involving over travel can also damage or even destroy a sensor causing failure and expensive unplanned downtime. Manufacturers often try to remedy this with in-house manufactured spring loaded out-feed mechanisms but those are expensive to make by experienced tool and die personnel who have more important things to do . Over the years, I’ve seen this as a pervasive problem in the stamping industry. Many of these issues can be solved with the use of a simple yet effective  sensor actuator system known as a plunger probe.

Plunger probe solves a few key issues in Progressive stamping:

  • The flexible trigger/actuation point is fully adjustable to meet sensitive or less sensitive activation points, not possible with “fixed” systems with substantial “over travel” built into the design.
  • It is fully self-contained (minimizing any risk of sensor damage and resulting unplanned machine down time).
  • The device can be disassembled and rapidly cleaned, reassembled, and placed back in service in the event that die lube or other industrial fluids enter the M18 body that can potentially congeal during shut down periods.

2 Solutions for Preventing Catastrophic Metal Forming Events

Have you ever heard the phrase, “Nine pounds of stuff in a one pound bag?”, or otherwise known as the “Blivet Effect?”

I’ve recently experience this, actually four incidences in three different companies to be exact. It revolves the wrong shut height.  When the recipe in a press doesn’t match die dimensions, or when the die dimensions are estimated, some bad things can happen.

In all of these companies, stamping presses of various tonnage ratings were run with a die that was over shut height dimension (the first hit caused a kaboom!).  Dies were locked up so badly, that they had to be torched, cut, and/or mechanically coaxed out.  In all cases, it took several days for this process to take place, causing lost production and significant down time (not to mention the financial loss and aggravation for a multitude of employees).

In order to eliminate these situations, here are two off-the-shelf electronic solutions that can be installed:
