Abstract
An apparatus for forging may include a moveable first tooling member configured to form a workpiece upon impact with the workpiece, a moveable second tooling member configured to form the workpiece upon impact with the workpiece, wherein the first tooling member and the second tooling member are each moveable relative to one another, and wherein a net momentum of a simultaneous impact with the workpiece by the first tooling member and the second tooling member is approximately zero.
Claims25
An apparatus for forging comprising:
- a machine frame;
- a first tooling member connected to and moveable relative to said machine frame, wherein a workpiece is coupled to and moves with said first tooling member, and wherein:
- said first tooling member and said workpiece combine to define a first mass,
- said first tooling member and said workpiece have a first impact velocity at a first impact position, and
- said first tooling member and said workpiece have a first momentum at said first impact position;
- a second tooling member connected to and moveable relative to said machine frame opposite said first tooling member, wherein:
- said second tooling member defines a second mass and has a second impact velocity at a second impact position,
- said second mass is at most twenty percent of said first mass, and
- said second tooling member has a second momentum at said second impact position;
- a first velocity sensor configured to detect at least said first impact velocity;
- a second velocity sensor configured to detect at least said second impact velocity;
- and
- a controller configured to adjust at least one of said first impact velocity and second impact velocity such that said second momentum is within twenty percent of said first momentum,
- wherein:
- said second tooling member impacts said workpiece positioned on said first tooling member within an impact zone defined by said first impact position and said second impact position, and
- a position of said impact zone relative to a first initial position of said first tooling member and a second initial position of said second tooling member is variable.
