  • Patent number: 7353680
    Abstract: The compression spring former disclosed by the present invention contains an external diameter mechanism, spacing mechanism, wire-feeding mechanism, cutting mechanism, length-detecting mechanism, sorting mechanism, and microcomputer control mechanism. Within the working range, specific springs can be formed simply by inputting the parameters describing the external diameter, spacing, roll number, and other allowance requirements. The control mechanism has a built-in length detecting and automatic sorting mechanism, which can modify the spring spacing according to different free heights, ensuring the allowance of free height. The cutter has a working mode for repeated cutting. The lowest point of the cutter shaft is set to “0” degrees for cutting the springs. If the cutter swings from positive 20 degrees to negative 20 degrees, or from negative 20 degrees to positive 20 degrees, the spring will be cut. That is to say, a spring is produced in every rotation of 40 degrees.

  • Patent number: 7325430
    Abstract: Disclosed herein is a method for improving the formability of an aluminum alloy sheet by locally modifying the surface of the aluminum alloy sheet. The method comprises: a sheet fixing step of fixing a sheet to be locally surface-modified; and a local surface modification step comprising adhering a probe closely to a region of the fixed sheet, which is in need of surface modification, by the application of pressure, and then rotationally moving the probe on the region at high speed. According to the method, the region of the sheet in which a fracture can occur due to the concentration of strains and stresses during the formation of the aluminum alloy sheet into a product is subjected to local surface modification so as to improve the formability of the aluminum alloy sheet compared to the parent metal, so that the aluminum alloy sheet can be easily formed into a product.

  • Patent number: 6915673
    Abstract: A worm is formed by rolling to reduce the number of processing steps while ensuring the worm accuracy satisfactorily. A work material is positioned between a first rolling die (100) and a second rolling die (101) by rotation of the rolling dies and a servomotor (76) for feeding the work material. When the lead angle of a worm is large and there is a large difference between the finished diameter and the blank diameter, the lead angle changes during the progress of rolling process, resulting in occurrence of through-feed. A slide plate (55) is freely slidable on a slide (53). Therefore, when through-feed occurs owing to the lead angles of the first and second rolling dies (100) and (101) and the workpiece, the slide plate (55) slides freely, and this is detected with a detecting sensor. The rotation of the first and second rolling dies (100) and (101) is stopped.

The sensor includes coils disposed in a signal coupling relationship and during the forming process, a signal applied to one of the coils induces a signal in the coil, producing a response signal that varies linearly as a function of the amount of overlap between the sensor and the sheet metal blank as the sheet metal blank is drawn into the deformation zone. A feedback signal produced from the response signal is used to control a parameter of the forming process as a function of retreat of the edge of the sheet metal blank into the deformation zone.

  • Patent number: 6269677
    Abstract: Apparatus and method to facilitate the insertion, alignment, and bending of metal sheets in a press brake machine is described herein. Automated insertion of properly aligned sheets into a bending machine can be accomplished using a press brake that includes at least two press brake fingers that act independently with respect to one another to determine whether the sheet has been received by the respective finger. The fingers are electrically coupled (via the sheet itself, for example) to a processor that communicates with. a robot. As the robot inserts the metal sheet into the press brake, it adjusts the alignment of the sheet until the sheet contacts the back planes of both press brake fingers. An electrical connection is formed when the metal sheet is received by the fingers (which are maintained at a nominal potential of 24V). When electrical connections are formed with both fingers, the processor tells the robot that the sheet is aligned and bending of the sheet can begin.
