Inside the Shell Press: The Shell Forming Process Explained
This video provides a detailed breakdown of the Shell Forming Process, highlighting the key steps and components involved in transforming aluminum coil stock into fully formed shells.
Step-by-Step Shell Forming Process
- Feeding and Alignment
- Coil stock is fed into the die set and precisely aligned with the cutting edge.
- Blanking and Drawing
- The cut edge, blank, and draw die cut a circular blank from the coil stock.
- The upper piston and inner pressure sleeve form the blank over the fixed die core ring, shaping the initial shell.
- Countersink and Panel Formation
- The die center and panel punch create the countersink and panel, defining the final shell geometry.
- The panel punch completes the shaping process, leaving an uncurled shell ready for the next step.
- Ejection and Curling
- Air lifts the shell, which is pushed sideways out of the die set by the ejector block.
- The shell enters the curler, where it is spun and progressively squeezed to create the full curl.
- Final Discharge
- Once the curl is complete, the shell exits through the curler hub and is discharged via the exit track, ready for further processing.
