In a press machine having a die cushion device which supports a cushion pad and which generates a die cushion force when a slide of the press machine is lowered, the wrinkle generation detection device includes: a slide position detector which detects a height position of the slide; a cushion pad position detector which detects a height position of the cushion pad; and a computing unit which consecutively calculates a deviation between the height position of the slide detected by the slide position detector and the height position of the cushion pad detected by the cushion pad position detector, during a time period from the start of forming of a material by the slide lowering to the end of the forming, wherein a wrinkle generated in the material is detected based on an increase of the deviation consecutively calculated by the computing unit.

A secondary light curtain for preventing injury to an operator of a press brake during formation of a second flange on a workpiece and a method for using the same. The secondary light curtain detects intrusion by the operator into a crush zone, i.e. the area, between the ram and the leading edge of a prior formed flange. In order to provide for ready adjustment of the height of the secondary light curtain, a mounting bracket having a longitudinal mounting slot, and a cooperating secondary angle bracket are provided. The mounting bracket of the present invention allows the secondary light curtain light assemblies to be mounted directly on the front or side of the ram.

Control method for a press installation and installation, where the installation includes a servo press, a conveyor device for conveying pieces from a position of origin to the servo press, and a controller. The controller controls the movements of the conveyor device and of the servo press by means of one and the same master signal, causing a synchronized actuation of both. In the method, the pieces are conveyed to the position of origin and during the travel thereof until reaching the position of origin, the passage of the pieces through a predetermined position of reference before the position of origin is detected, and depending on the detection, the master signal is adjusted for adapting the actuation speed of the servo press.

One aspect is a hydraulic ironworker system having a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces. An accessory tool is coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker. A remote pushbutton assembly is removably coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system. A safety plug assembly is configured to alternately couple to the harness assembly in place of the remote pushbutton assembly. Power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies is attached on the harness assembly.
