摘要： A control system includes an electro-hydraulic servo valve configured to move about a plurality of positions in response to receiving an analog bi-polar current signal. An electronic field programmable gate array (FPGA) generates first and second digital pulse width modulation (PWM) signals according to an adjustable duty cycle. An electronic bridge circuit is in electrical communication with the FPGA to convert the first and second digital PWM signals into the bi-polar current signal. An electronic current sensing circuit is in electrical communication with the bridge circuit, the current sensing circuit configured to generate a digital feedback signal indicating an average current level of the bi-polar signal. The FPGA controls the duty cycle based on at least the average current level indicated by the digital feedback signal.

摘要： The die cushion force setting apparatus according to an aspect of the present invention allows die cushion forces (component forces) acting on plural driving shafts to be set easily, makes it easy to apply strong or weak die cushion forces to a complex-shaped drawn part in a plane of a cushion pad, and provides a smooth die cushion force distribution. An operator manually enters a total die cushion force, axial component force of a left front hydraulic cylinder, and center-of-force position by operating an input device. Based on the information entered via the input device, the numerical computing device B1 calculates axial component forces of three hydraulic cylinders through numerical computations. The one axial component force thus entered and three axial component forces thus computed numerically are set as the axial component forces of four hydraulic cylinders.

摘要： A fluid supply system controller includes a processor, a memory subsystem and fluid application code. The memory subsystem is coupled to the processor and stores data and instructions. The fluid application code causes the processor to perform the steps of receiving a workpiece width, a workpiece feed length, a workpiece stroke rate, a workpiece fluid thickness and a calibrated flow rate. The fluid application code then causes fluid to be periodically provided to the workpiece for a fixed duration responsive to the received workpiece width, workpiece feed length, workpiece stroke rate, workpiece fluid thickness and calibrated flow rate.

摘要： The position of a controlled system is regulated with a hydraulic actuator, which is directly linked to a hydraulic pump. The pump is driven in either direction by an electric motor, which is controlled by the output of rotatory direction and driving power generated from a controller based on a desired position and the feedback input of the actual position of the controlled system and the rotatory speed of the electric motor. The controller further includes a gain-variable amplifier for amplifying a deviation of the controlled value from a desired value with a gain characteristic curve of a shape appropriate to the controlled system, attaining a stable and well follow-up control of position.

摘要： The hydraulic controller is for controlling the operation of a plurality of hydraulically controlled devices. Hydraulic fluid may be selectively distributed by the controller to various controlled hydraulic devices in a timed and predetermined sequence. The timing of the distribution of hydraulic fluid by the controller can be quickly and easily varied by various control knobs on the controller to thereby vary the timed operated period of the various machine operations controlled by such devices without affecting the timed operation of other machine operations. The controller is supplied with a source of hydraulic fluid under a generally constant pressure. Cam means are associated with each of a plurality of fluid flow distributing valves for operating such associated valve members in a predetermined sequence of valve positions upon advancement of the cam means relative thereto. Drive means including a pair of opposed indexing and timing device pistons; advance the cam means relative to the valves to operate them in sequence of positions and in operating intervals or dwell periods thereof. The indexing piston has an effective working diameter in its cylinder which is greater than that of the timing piston such that it normally overrides the timing piston. The cam drive means includes lost motion means for allowing the cam means and associated distributing valves to dwell during timing strokes. Fluid flow restrictor means adjustably restrict the flow of fluid through the venting means to control the speed of the timing stroke and thereby provide an adjustable timed interval of operation of the device then being operated.
