  • Patent number: 10406742
    Abstract: The apparatus has a bending/cooling station mounted on a base. A tube clamping assembly is mounted on the base, movable towards and away from the bending/cooling station and including a tube clamping assembly and a tube rotation assembly. A tube heating assembly is mounted for movement between the bending/cooling station and the tube clamping assembly. Servomotors move the tube clamping assembly and the tube heating assembly, rotate the tube clamping assembly, and actuate bending at the bending/cooling station. The apparatus is controlled by PLC or PC-based programs, which effect movement via servomotors and control other parameters such as heating and cooling times and temperatures. Bending and cooling the tube at a first bend location, and heating the next desired bend location, take place in overlapping time windows, before advancing the tube to position the next desired bend location of the tube at the bending/cooling station.

    Abstract: A method is provided to determine a quality acceptance criterion using force signatures measured on a first and a second set of elements. The first set has no quality defect and the second set has a deliberate quality defect. Selection of an initial subset of time points is based on statistical analysis of the force data on the force signatures in the two sets. The quality acceptance criterion includes a quality threshold established using Mahalanobis Distance (MD) values and the MD values are produced from force data at a selected initial subset of time points for each element in the two sets. An output of the determined quality acceptance criterion is using the defined quality threshold to separate an element having a force signature into a group of elements having no quality defect or into a group of elements having a quality defect like the deliberate quality defect.

    Abstract: A method and apparatus for detecting a turned blank at a workstation in a progressive forging machine comprising simultaneously monitoring both the force on a tool in the workstation and the crank angle of the machine, determining a reference crank angle when the tool is subjected to a force at the workstation about to deliver a blow and a blank in the workstation is properly angularly aligned, operating the machine to forge blanks in a normal manner when a force on the tool at the workstation occurs substantially at the reference crank angle, and interrupting said normal manner when the force on the tool at the workstation occurs before said reference crankshaft angle to enable the blank being formed at the workstation to be separated from remaining blanks being forged in the machine.

  • Patent number: 7779660
    Abstract: The invention relates to a method for deep rolling the passes or radii on the transitions between journal and cheeks or flanges of crankshafts by means of a deep rolling device (1) of a deep rolling machine, said deep rolling device having a lazy tongs-type design. The deep rolling device (1) has two tongs arms (2, 3) that are articulated to each other via a pivot joint (24). The corresponding outer ends (4, 5, 9, 10) of the tongs arms (2, 3) are provided with a deep rolling tool (6) or a force generator (11) for generating the deep rolling force. A measuring tape (18) and a sensor (19) which are provided on the pivot joint (24) are used to measure the impression depth of the deep rolling rollers (12) under the effect of the deep rolling force. A measuring device (22) mounted on the exterior (21) of a tongs arm (2) is used to measure the degree by which the tongs arm (2) bends under the effect of the deep rolling force.

  • Patent number: 7765841
    Abstract: A disclosed device and method are useful for monitoring a tube bending process. An example sensor detects a force associated with moving a mandrel in tubing during at least a portion of a tube bending process. The detected force is used to determine a quality of the tube bending process. For example, a detected pulling force provides an indication of whether a bent portion of a tube is within an acceptable range of a desired configuration. The detected pulling force is also useful to provide an indication of whether a condition of a mandrel or a machine used during the process is as expected.

  • Patent number: 7757526
    Abstract: A method for changing a force control gain expressed as a ratio of force error to velocity command value in a control circuit performing a force control of a servo motor driving a die cushion disposed opposite to a slide in a press machine. The method includes: obtaining a difference between a displacement of the slide and a displacement of the die cushion in a state in which the slide and the die cushion collide with and are exerting force on each other; detecting the force when the difference of the displacements is obtained; calculating a spring constant of a structural portion based on a proportionality between the difference of the displacements and the force, when regarding the structural portion including the slide and the die cushion as an elastic structure; and changing the force control gain based on the spring constant using a fixed proportionality that exists between the force control gain and a reciprocal of the spring constant.

  • Publication number: 20100139351
    Abstract: A method for determining the quality of a crimped connection between a conductor and a contact includes operating a crimping device to exert a crimping force on the conductor and the contact. From the crimping force curve that occurs during the crimping, a normalized force-distance crimping force curve is derived and a compression area is determined which lies under a reference crimping force curve. The crimping force curve and the reference crimping force curve are subdivided into several zones, the subdivision taking place under consideration of the size of the compression area. A further area that lies under the crimping force curve is determined and used to infer the quality of the crimped connection. A device for performing the method is provided.

  • Patent number: 7658089
    Abstract: A system and method for monitoring clinched joints senses lateral displacement of die segments during formation of a joint, which depends on joint button diameter. The system determines whether a joint is acceptable by correlating acceptable button diameter with acceptable amount of punch advancement. A predetermined number of unacceptable joints indicates excessive punch and/or die wear.

  • Patent number: 7650771
    Abstract: A high-pressure press includes a pressure vessel surrounded by a force-absorbing press frame. The high-pressure press also includes a detection structure for detecting changes in length of at least one column comprised in the press frame, the changes in length depending on the pressure inside the pressure vessel. The detection structure includes a limit switch, which is adapted to detect if the change in length of the column has reached a threshold value and, in that case, interrupt a pressing operation in progress and reduce the pressure inside the pressure vessel.
