Components for Punch Press Controls

 

 

 

 

A most important aspect of double valve design is the incorporation of two separate 3/2 normally closed valve elements which are interconnected within a common valve body assembly. Each of the elements is operated by its own 3/2 normally closed solenoid pilot valve. When simultaneously energized, both main valve elements are operated simultaneously. The probability of both valve elements malfunctioning on the same cycle is extremely remote.

A mechanical power press or other hazardous machine using a pneumatically controlled clutch and brake mechanism should use a double valve with a self-contained monitoring device and/or external monitoring system which inhibits further operation of the valve and machine in the event of a failure within the valve. Of course, a double valve is just one of the components in a press control system, and any other elements of the system should be planned with safety as a primary consideration.

Rotary Cam Switch with Drive Check
No. 310A
The primary components which make up the Rotating Cam Limit Switch are Snap Action Switches and the Micro-Adjust Cams. The Micro-Adjust Cam Block consists of two cams with 180 degree lobes which can be adjusted relative to the cam shaft by simply rotating the Adjusting Disc. No tools are required to make this adjustment. The adjusting disc can be manually rotated as shown in the photograph. The cam block has a self-locking polyurethane gear which automatically locks the cams relative to the cam shaft, when the required contact setting has been obtained.
