摘要： A trim die for sheet metal or other materials is provided to trim the entire circumference of a drawn part. The trim die includes a trim plate with a connected trim punch moveably mounted in a stripper plate. Cam punches with cam lobes engage cam followers on the trim plate to impart motion to the trim die. The trim die of the present invention minimizes displacement of the part to be trimmed, including the excess material, and therefore is compatible with progressive dies. The corresponding method of trimming a part is also provided.

摘要： Knockouts are formed in electrical fixtures, such as connector boxes made of plastic sheet material, by punching the knockouts from plastic sheet or blanks prior to shaping into the fixture or by shaping the fixture and then punching out the knockouts. By resiliently supporting the material surrounding the knockout area on the punch side and resiliently biasing a knockout stripper against the surface of the knockout opposite that contacted by the punch, knockouts can be punched out and replaced in the material in a single operation if the opposite biasing forces of the support and knockout stripper are properly correlated.

摘要： Mechanism for and method of shifting cam mechanisms in a press for pressing workpieces with depressed portions comprise a combination of a first single cam mechanism for retracting a die by a distance equal to the depth of a depressed portion of a workpiece and a second single cam mechanism for pressing the workpiece to work the depressed portion. Said single mechanisms are provided between a bottom form and a top form being vertically movable toward and away from said bottom form. Said first single cam mechanism is composed of a pad positioned downwardly of said top form, a pin mounted on and extending downwardly from said pad, a first cam follower mounted on said bottom form and movable in response to depression of said pin, and a second cam follower mounted on said bottom form. Said second single cam mechanism has a punch for punching the depressed portion of the workpiece and is composed of a fixed cam mounted on the top form, and a third cam follower mounted on said bottom form and supporting said punch.

摘要： A piercing die assembly for punching a plurality of radially extending holes in a tubular member. The assembly having an open end for receiving a tubular member to be punched. The die assembly having structure for supporting the tubular member in a pre-punching position including radially inner and outer die walls for backing up inner and outer wall surfaces of the tubular member to be punched. A plurality of spaced radially movable punch assemblies are operatively connected with the die structure and having a series of radially movable punches. The punch assemblies having bearings positioned at radially outer ends of the punches and each bearing and its associated punch being radially movable simultaneously together. A vertically movable ring-shaped actuator member is positioned radially outwardly of the punches and is movable axially from a pre-punching position to a post-punching position.
