How to Decrease Downtime on Metal Die Machinery

With most sheet metal die changes, the shut height value must be changed on the machine. Fast, efficient changes of this shut height will decrease downtime between jobs. The distance that the ram travels is specified or fixed for each press.

The 'daylight', or open distance between the bed and the ram can be varied by changes of the shut height.
The shut height is changed by increasing or decreasing the length between the pitman arm and the slide. This is typically accomplished via a motorized nut/screw assembly mounted between the pitman arm and the slide.

Two Solutions Securing Longevity and Efficiency
Gemco offers two methods of monitoring shut height. The
Gemco 2110 Shut Height Monitor in combination with the rugged 953VMax Linear Displacement Transducer (LDT) mounted between the pitman arm and the slide will give the direct displacement of the slide adjustment. Another recommended solution is to have a Gemco 1986 Resolver mounted off, of the screw with a 2110 Shut Height Monitor in the "Turns Counting" mode. The resolver system can generate rotary to linear shut height position information. The advantage of having a linear displacement transducer is that the unit reads actual displacement and is not affected by gearing backlash. The advantage of a resolver is the ease of installation.

Gemco truly understands stamping and is the only manufacturer that can supply a complete system including a 2110 Shut Height Monitor,
953 VMax LDT , Universal Mounting Kit, and Cable Termination Kit. This system simplifies the installation process and ensures longevity.

Gemco 953 VMax LDT and 2110 Shut Height Monitor provide absolute position feedback in the harshest environments, the 953 VMax is tested to handle 30G of vibration and up to 1000G of shock.
