  • Patent number: 7752881
    Abstract: Press driving modules are provided to permit a standardized press design. The presses of a press line are equipped with always identical press driving modules, and the pressing force of the presses is varied only by the adaptation of the number of press driving modules. The press driving modules each contain two driving devices, respectively, that interact parallel or in series and have different characteristic curves. In particular, they have different maximal traveling speeds and different maximal forces. They can also have a different design with respect to their positioning capability and path resolution. This concept permits not only a standardization of presses of different performance classes within a press line but, beyond that, the largely free definition of characteristic path-time curves of the slides, and thereby finally also a freer design of workpieces, particularly of vehicle body parts.

    Abstract: A control device for a die cushion mechanism, for carrying out force control with high accuracy and at a high speed. The control device for controlling the force generated by the die cushion mechanism utilizes a press working cycle which is repeatedly carried out. A correcting part of the control device corrects each deviation in one working cycle based on a time-series of deviation data in the just before press working cycle. By repeating this operation, the deviation between the detected value and the commanded value may be converged toward zero. Therefore, the deviation may become smaller than that of the conventional feedback control, whereby it is possible to respond to a change in the commanded value in a short time.

During each dwell of the form gear, a form tooth of a punch unit at the forming station is driven by an electronically-controlled linear servomotor into the cavity to at least partly form a corrugation in the strip. During each operating stroke of the punch unit, a hold finger clamps the immediately outgoing node of the corrugation that just left the forming station against the immediately outgoing tooth of the form gear, thus preventing any part of the outgoing corrugation from being pulled back into the cavity and ensuring that the next corrugation is formed solely from a segment drawn in from the incoming foil.

    Abstract: A vertical position of a ram (5U) is directly detected by a ram position detecting means (11), and a first speed arithmetic operating portion (65) determines a first ram moving speed on the basis of a change of the detected position. At the same time, a second speed arithmetic operating portion (67) determines a second ram moving speed on the basis of a rotational number of a servo motor (39) which is determined by a servo motor rotational number detecting means (40). A comparing portion (69) compares the first ram speed with the second ram speed, and in the case that a difference is equal to or more than a predetermined amount, a judging portion (71) judges that an abnormality exists so as to immediately stop the servo motor (39) and stop a working.

  • Patent number: 6418768
    Abstract: A crimping including a stand at which a motor and a transmission are arranged. Moreover, first guides, at which a crimping bar is guided, are arranged at the stand. A shaft driven by the transmission has an eccentric pin at one end, and a resolver for detection of rotational angle is coupled to the other end. The crimping bar includes of a slide member guided in the first guides and of a tool holder with a retaining fork. The slide member stands in loose connection with the eccentric pin, wherein the rotational movement of the eccentric pin is converted into a linear movement of the slide member. The tool holder actuates a tool, which together with an anvil produces the crimp connection. An operator terminal is provided as an interface between the operator and the crimping press. The operator terminal includes a rotary knob and a keypad for input of operating data and commands into a control. A display is provided for visualization of data.

  • Patent number: 6401514
    Abstract: A sheet fabrication machine includes a direction convert mechanism that converts the movement of the driving mechanism along one direction to drive the tool for fabricating a worksheet in another direction. The direction conversion mechanism includes a carriage plate whereon a plurality of direction convert units may be mounted. Each of the direction convert units may be configured in the form of a cam that has a number of contact surfaces each having a preset angle. The carriage plate is interposed between a drive contact, such as for example a rotating mechanism, and the ram that presses against the tool of the machine. When one of the cams in the carriage plate is positioned into alignment with the rotating mechanism and the ram, the rotating mechanism is moved along the one direction so that it applies a biasing force against the cam.

  • Patent number: 6145366
    Abstract: Damage to the dies due to a die collision caused by an input error of bending data etc. is avoided without use of a specialized device for pressure detection. A die interference checking mode is provided for setting the pressure of the ram, which supports the movable die, to a value that does not cause damage in the event that the movable die and the fixed die interfere with each other and for driving the ram so as to create the set pressure. A die interference determining step is further provided in which it is determined whether the movable die and the fixed die have interfered with each other in the die interference checking step, and if it is determined that the dies have interfered, the movement of the ram is stopped, and if it is determined that the dies have not interfered, the die interference checking step is cancelled and the operation of the press brake proceeds to an ordinary bending step.

  • Patent number: 6089073
    Abstract: A drawing apparatus in a press or similar forming system has a blank holder which can be acted upon by one or optionally several pressure cylinders. Blocking devices are provided which act, in one case, directly upon a pressure cheek supporting the blank holder and, in another case, indirectly upon the pressure cheek by way of an articulated train or transmission train. Thereby, an unintentional lifting or lowering of the blank holder is prevented when the press is inoperative.

    Abstract: A method of controlling a terminal press attaching device by providing a elevating crimper for crimping terminals onto exposed conductors of the cables, setting an anvil opposite to the crimper, and elevating the drive means including a servo motor. More specifically, the crimp height for press attached terminals is monitored, a detected height and the predetermined set value are compared to control said drive means such that the detected height is made equal to the set value. Thus, the crimp height of the terminal to be attached (or the crimper height) is automatically and easily adjusted.
