Pneumatic Impact Press
Impact Press Principles of Operation
Since these presses operate on a spring-actuation principle, the degree of impact is easily adjustable. The press contains a spring that is compressed during energy section travel. Press capacity can be easily adjusted by increasing or decreasing spring size and/or tension. When the release point is reached, the compressed energy is discharged causing the internal hammer to deliver the powerful impact. There are a variety of sizes of springs available for each of our impact press models. Vertical travel is accomplished by a gear and rack arrangement.
Step 1 - The energy section advances towards the workpiece by gear rack and pinion, powered either automatically by double-acting pneumatic cylinder (if using a pneumatic unit with hand controls) or manually by the operator pulling down the lever.
Step 2 - Once the press stroke is engaged and the workpiece is contacted, the press stroke continues. The workpiece is held in place by the pressure from the energy section (this is a significant safety feature). The impact spring is compressed and builds force as the press continues to maintain contact with the workpiece.
Step 3 - When the ball bearings reach their release point, the powerful impact is discharged. The impact spring delivers force to the hammer, which in turn strikes the plunger (tool holder). You can control the amount of impact depending on which spring you choose and how much tension is applied.
