| A set of dies are composed in order to remove excess metal from a casting with a press. A method of removing the excess metal from the casting includes the steps of attaching a cutter to one of the stationary die side or the movable die side; setting a work on the other side; and punching excess metal of the work into a recess shape by one punching motion of the movable die with a plurality of blades from the first blade, which is smaller, to the final blade, which is larger and protruded, when the excess metal of the work is removed by a punching motion of the movable die conducted on the stationary die. A cutter includes a row of blades in which a plurality of blades are arranged step-wise having a change in the form from the first blade, which is smaller than the final shape of the excess metal to be punched, to the final blade, the shape of which is the same as the final shape. The row of blades from the first blade to the final blade are arranged so that the first small blade can be used ahead of other blades and the other blades can be used in the order of punching motions. | ||||||

| A pneumatic tool (20) for impacting a workpiece (22) is provided. The tool (20) comprises a casing (42) defining a chamber (48). A piston (54) is slidable within the chamber (48) along an operational axis (A). An exhaust valve (100) controlled by a pilot valve (200) slides the piston (54) by selectively introducing and releasing pressurized fluid into and out from the chamber (48). The pilot valve (200) includes a valve housing (202) defining a pilot chamber (204) with a plunger (206) slidable in the pilot chamber (204). The pilot valve (200) actuates the tool (20) by quickly releasing pressurized fluid from the exhaust valve (100) to atmosphere. The pilot valve (200) includes a spring-biased annular seal (214) that is releasable from a poppet seat (222) to perform this function. | ||||||
| 238 | Compliant cutoff saw assembly | US11181615 | 2005-07-14 | US20050247175A1 | 2005-11-10 | Christopher Cooper |
| 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. | ||||||

| A method of finishing like castings wherein the exact dimensions of the casting are not known requires the steps of traversing the casting along a fixed path impinging excess material on a reduction apparatus such as grinder at a fixed location such that a defined witness is produced on the excess material, measuring the difference from the witness to the casting parent material and adjusting the fixed path to remove the excess material to within a specified tolerance. | ||||||
| 240 | Self-centering trim punch | US10033232 | 2001-12-28 | US06769340B2 | 2004-08-03 | Mark Phlipot |
| Cast metal parts are created for use in making machinery. When these parts are formed, unwanted material remains in the openings of the parts. This material, called flash, must be removed. In the method of the present invention, the cast parts are placed on a platen of a trim press that has multi-part punches attached thereto that are configured to self-align with the openings in the cast part and operative to evenly remove the flash. The invention also relates to a punch that initially breaks through the flash with a stationary punch that removes a majority of the flash inside the opening of the cast part. Next, a moving or self-centering punch self-aligns to the opening in the cast part and operates to remove the remaining flash. The inventive punch may also include a mounting base for attachment of the multi-part punches to the plate or platen of the press. | ||||||
