摘要： In unloading a press, it is desirable to provide automatic unloading without the need for operators, even in situations requiring a definite stacking order in containers located next to the press. To achieve this automatic unloading, extraction grippers and a carrier frame are provided which can be moved in three directions which are at right angles to each other by servo drives controlled by a continuous-path numerical control unit.

摘要： In control drives for high speed blanking presses, a serious problem of excessive tool wear arises from increases in the immersion depth of a top tool into its associated bottom tool when the stroke frequency increases. To overcome this, a control drive is provided wherein the top tool is held at a substantially constant immersion depth in the opening in the bottom tool over the entire stroke frequency range of the press. A measuring instrument detects the stroke frequency. This detected frequency is fed into a control circuit programmed with a characteristic corresponding to either immersion depth or ram adjustment as a function of stroke frequency. The output of the control circuit is a control signal coupled to a drive motor to maintain the constant immersion depth.

摘要： In automated press systems it is desirable to be able to control the actuators of an automation system associated with the press based on the speed of the press. To accomplish this, a circuit arrangement is provided which includes a pulse generator for producing a coded signal indicating the position of the press based on a press speed signal. An evaluation circuit having a parallel arrangement of a converter and a process control circuit receives these coded position signals. The outputs of the converter and process control circuit control the actuators of the automation system through pulse converters and positioning control circuits (e.g. speed and position control loops). Information as to the number of press strokes is also provided to the pulse converters through a generator. The converter can be an electronic curve shaper which controls the actuators when the press ram is moving, while the process control circuit can be a CNC control circuit which controls the actuators when the press ram is stopped.
