  • Publication number: 20100044409
    Abstract: The present invention includes a method of determining the correct timing of a material release mechanism of a material feed mechanism and includes the steps of: cycling a press mechanism through a working portion of a tooling mechanism; monitoring the press mechanism position; determining, by a location device, the desired timing for the material release mechanism to release contact with material; and correlating the desired material release mechanism timing to the press mechanism position.

  • Patent number: 7287678
    Abstract: This invention includes a method of determining the correct timing of a material release mechanism (42) of a material feed mechanism (14) and includes the steps of: cycling a press mechanism (12) through a working portion of a tooling mechanism (17); monitoring the press mechanism (12) position; determining, by a location device (58), the desired timing for the material release mechanism (42) to release contact with material (18); and correlating the desired material release mechanism (42) timing to the press mechanism (12) position. The present invention also is a stamping system (10) for working the material (18). This stamping system (10) includes a press mechanism (12) having a tooling mechanism (17) configured to punch holes (66) in the material (18). The stamping system (10) also includes a material feed mechanism (14) to feed material (18) to the press mechanism (12), and this material feed mechanism (14) includes a material release mechanism (42).

  • Patent number: 5915293
    Abstract: A method for compensating for the variation in shut height of a press during stamping and forming as it is starting and stopping comprising user input of the minimum press speed at which feeding of feed material to the press should commence, monitoring of the actual press speed, and feeding of the feed material only when a minimum press speed representing a desired press shut height has been achieved. A method for inputting a desired shut height range, monitoring actual shut height and feeding feed material only when the actual shut height is within the desired shut height range is also disclosed.

  • Patent number: 5884542
    Abstract: A method and apparatus for protecting a die from damage due to material jams in material stamping equipment wherein feed material is stamped in a die and then advanced through the die by action of press feed rolls powered by a press feed roll drive motor. The position error of the press feed rolls or the torque of the press feed roll drive motor is monitored during the advance of the feed material through the die. The monitored position error of the press feed rolls or the monitored torque of the press feed roll drive motor is then compared to the expected position error of the press feed rolls or the expected torque of the press feed roll motor, respectively.

  • Patent number: 5868296
    Abstract: The present invention provides for a press feed apparatus for use in feeding stock material to a high speed automatic press. The feed roller is driven by a servo motor integral with the shaft of the roller, the feed roller release mechanism is infinitely adjustable, and a feedback system is used to accurately determine the position of various shafts. The apparatus is controlled electronically, by a microprocessor or the like, which permits the press feed to be electronically geared to the press and accurately operate at high speeds.
