US Patent:

8061244, Nov 22, 2011

Filed:

Jul 14, 2005

Appl. No.:

11/181615

Inventors:

Christopher W. Cooper - Hoover AL, US

Assignee:

Action Machinery Company of Alabama, Inc. - Helena AL

International Classification:

B26D 1/00
B26D 3/00

US Classification:

83 13, 83914

Abstract:

A cutoff saw assembly incorporates a robot assembly with a compliant cutting apparatus to remove various undesired metal extensions from a casting. The assembly cooperatively and conjunctively controls the position of the casting using the robot assembly and the force exerted by the cutting apparatus on the casting using a compliance control system. The compliance control system includes a compliance actuator that is connected to a compliance regulator. Both the robot assembly and the compliance control system are connected to a system controller. The compliance actuator is connected to the cutoff blade to actively vary the force of the cutting blade with respect to the casting. The compliance regulator, which is connected to the system controller, will measure and regulate the pressure in the compliance actuator, such that the robot assembly and compliance control system can apply the required force to cut the casting.

Appl. No.:

9/372419

Inventors:

Christopher W. Cooper - Hoover AL

Assignee:

Action Machinery of Alabama, Inc. - Helena AL

International Classification:

B25D 900

US Classification:

173211

Abstract:

A improved apparatus for decelerating a piston and impacting rod assembly within a single stroke foundry impactor utilizing a non-metallic deceleration piston slidably positioned within a pressurized deceleration chamber mounted proximate the end of the bore containing the impactor piston and impacting rod assembly. The deceleration piston is biased towards the impactor bore by pressurization of the deceleration chamber, such that upon a stroke of the impactor, the residual kinetic energy of the piston and impacting rod assembly is absorbed by the biased deceleration piston.
