摘要： 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. The feed material is moved backwards to a previous position from which the feed material advanced, typically the position at which the feed material was last stamped, if the monitored position error of the press feed rolls or the monitored torque of the press feed roll drive motor deviates by more than a tolerance value from the expected position error of the press feed rolls or the expected torque of the press feed roll motor, respectively. Operation of the material stamping equipment may stopped after the feed material is moved back if desired.
摘要翻译： 一种用于保护模具免受材料冲压设备中的材料堵塞造成的损坏的方法和装置，其中将进料材料冲压在模具中，然后通过由压力进给辊驱动马达驱动的压力进给辊的作用而推进通过模头。 在进给材料通过模具的进给期间，监测压力进给辊的位置误差或压力进给辊驱动马达的扭矩。 然后将压力进给辊的监视位置误差或压力进给辊驱动电机的监控转矩分别与压力进给辊的预期位置误差或压力进给辊电机的预期扭矩进行比较。 如果压力进给辊的监视位置误差或压力进给辊驱动电机的监视转矩，进给材料向后移动到进给材料从其进给的先前位置，通常是进料最后冲压的位置 分别从压力进给辊的预期位置误差或压力进给辊马达的预期扭矩偏差大于公差值。 如果需要，送料回送后，材料冲压设备的操作可能会停止。

摘要： A press feed is provided having a simple, low-friction, low-inertia linkage mechanism to positively drive feed rolls or grippers of the press feed with substantially uniform pressure. The linkage mechanism includes a three-link assembly having first and second substantially parallel links and a third cross link pivotally connected to the first and second links. The first and second links are pivotally mounted to a housing of the press feed substantially equidistant from the connections to the third cross link. The third cross link has a groove extending substantially at right angles to the transverse axis of the third cross link extending between the connections of the third cross link to the first and second links. First and second slides are positioned in the groove in the third cross link and each slide is connected to a swing arm drivingly connected to the feed roll shafts such that upon operation of the press feed the third cross link moves through an arc defined by a preselected feed length to be fed by the press feed to the press.
