  • Patent number: 8984922
    Abstract: The invention relates to an apparatus (100) for positioning a tool (21) in a profile rolling machine, comprising a base (10) and at least one spindle (30) extending in a first bore (17) of the base as abutment for the tool (21). A retraction rod (25) serves as connection between the base and the tool (21). A tractive force for the retraction rod (25) is generated by an actuator (50) and the tool is pulled by the retraction rod (25) against a tool stop (23). The first bore (17) is locally expanded to form a cylinder chamber (12). A piston (40) is mounted in an axially displaceable manner in the chamber (12). A pressure medium (M) is introduced via a pressure connection (46) into the base (10) into the cylinder chamber (12) between the base and the piston (40) for applying a force (F1) on the piston (40).

  • Patent number: 8869578
    Abstract: In a can forming machine a system that determines the position of a reciprocating ram and allows for the domer to be repositioned automatically is provided. The system includes a punch position sensor assembly, a control system, and a domer positioning assembly. The punch position sensor assembly is positioned about the ram, preferably at the domer side of the last die. At this location, the punch position sensor assembly can determine the position of the ram as it enters the die pack during the return stroke. The control system receives data from the punch position sensor assembly and, if the ram is not substantially, concentrically aligned with the die pack on the return stroke, sends a signal to the domer positioning assembly to reposition the domer. This process may be repeated until the ram travels along a path substantially aligned with the die pack on the return stroke.

  • Patent number: 8024955
    Abstract: A die change method includes providing a press apparatus having a base and a ram, and a first die set including an upper die member and a lower die member. The lower die member is supported on the base and the upper die member is mounted on the ram. The ram is lowered into a closed, home position to mate the upper and lower die members and to perform an operation on a workpiece disposed between the die members. The ram is released from the upper die member. The ram is raised a minimum distance to provide minimal clearance for removing the upper and lower die members from the press. The mated upper and lower die members are moved out of the press with the workpiece held between the upper and lower die members.

  • Patent number: 7980112
    Abstract: A die having various features such as spring pockets and mounting provisions for a lifter bar that can be utilized to make a variety of dies. The dies may include pockets or other mounting features that provide for mounting replaceable plates that can be machined for mounting of die forming and cutting steels and other die components. The die shoe may include an array of pockets or blind holes for mounting nitrogen springs or the like for operation of forming steels and the like. One or more openings may be drilled in the replaceable plates above the pockets selected to receive nitrogen springs, with the remaining unused pockets being covered by the replaceable plate. The replaceable plate and pre-formed spring pockets thereby permit the die to be readily adapted for a particular die. The replaceable plates may be removed, and a replacement plate may be installed as needed for a new die.

  • Publication number: 20110154999
    Abstract: A system monitors vibration activity in a press machine environment and generates a signal indicative of vibration level severity. An accelerometer can provide measured peak acceleration data that serves as an indication of vibration level. The vibration measurement, is compared to a reference vibration level that corresponds to a run condition of desired operating parameters. A controller controls the press machine shutheight in accordance with the differential expressed in the comparison result. The consequent shutheight adjustment effects a change in the vibration activity that acts as a correction to the deviation in vibration behavior expressed by the differential.

  • Patent number: 7823430
    Abstract: A quick plastic forming (QPF) tool is provided in which a thermal gap is created that reduces or eliminates some of the conductive heat loss paths when the QPF tool is in an open position during part removal or sheet loading. By reducing conductive heat loss, a more precise temperature control for the QPF tool from manufacturing cycle to manufacturing cycle may be realized. The QPF tool may also have a thermal gap when the tool is placed in a semi-open position during idle times. The QPF tool may also include components for creating the thermal gap when the QPF tool is moved to the open position and control the lateral movement of the part forming section of the QPF tool as the part is moved between the open position and the closed position.

  • Patent number: 7818985
    Abstract: A bending apparatus is provided with a ram start-up device so as to be movable in a lateral direction. A controller moves the ram start-up device to a point in front of positioning points of abutments corresponding to points of selected edges of a workpiece. The bending apparatus includes a foreign object detector that detects the entry of a foreign object into a region of movement of the ram start-up device. A controller prevents the ram start-up device from moving when the entry of the foreign object is detected.

  • Patent number: 7810368
    Abstract: The invention is a multi-mode hammering machine that operates in a rigid mode, a flexible power hammer mode and a machine press mode to contour, shape and form sheet metal products. In all three modes, a ram is linearly stroked toward and away from a fixed die by a common ram drive assembly that includes a lever drive assembly and a reciprocating lever. The lever drive assembly moves in a rigid non-flexing manner. The reciprocating lever includes a rigid mode and a flexible mode. A conversion pin is used to engage one and simultaneously disengage the other. The lever drive assembly includes a control link that interfaces with a stroke adjustment mechanism. The gap adjustment mechanism is located at the fulcrum of the reciprocating lever. Both stroke length and gap are adjusted independently during the operation while the ram is cycling.

  • Publication number: 20100212469
    Abstract: A multiple punch and multiple die assembly has a workpiece protector comprising a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.
