Abstract
A method is disclosed for forming an article that includes the steps of filling a mold with a solid or particulate material, inserting a tool into the mold with a portion of the tool extending from the mold, and striking the tool with an impact ram to adiabatically coalesce the material in the mold to form an object having the shape of the mold. An apparatus for performing the method is also disclosed.
Claims23
A method of forming an article through adiabatic coalescence comprising the steps of:
- providing a mold;
- filling the mold with a material;
- placing a tool in the mold that extends from the mold;
- providing a striking unit;
- and,
- striking the tool with the striking unit with adequate force to adiabatically coalesce the material.
The method of claim wherein the striking unit is an impact ram.
A method of forming an article through adiabatic coalescence comprising the steps of:
- providing a mold;
- filling the mold with a material;
- and, providing a striking unit;
- striking the mold or the material with the striking unit with adequate force to adiabatically coalesce the material.
A percussion machine with a striking unit for emitting kinetic energy of such magnitude to cause adiabatic coalescence in a material, said striking unit comprising a first impact ram movable between two end positions and having two circumferential surfaces perpendicular to the axis of the impact ram, which surfaces can be influenced by liquid pressure and are of different sizes, the large surface, when under pressure bringing the first impact ram to its original position for a stroke.
