Abstract: Apparatus and a method for establishing setup parameters for use in a machine. In one embodiment a tooling component is removably mountable to a host machine. The tooling component includes a memory that contains information defining setup parameters for the host machine for use with the tooling component. A controller associated with the host machine reads the information from the memory and configures the host machine based on the information read from the memory. In another embodiment, an information carrying tag, is associated with the tooling component. The information carrying tag is read and the identifying information obtained from the tag is used by a controller to select a set of setup parameters from one or more sets of setup parameters stored in a storage device accessible by the controller. A mechanism is provided to precisely position the adapter on the base plate for the host machine to minimize variations in production using the setup parameters derived from the stored information.

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.

Abstract: A reduced force sealless connection mechanism is used in a strapping machine for forming a sealless connection of strapping material overlapped onto itself. The mechanism includes an upper and a lower punch support. The upper punch support includes two punches for engaging the strapping material. The lower punch support includes one punch. The upper punch support incorporates a stepped design such that one of the two punches mounted to the upper punch support is at a different height than the other punch mounted to the upper punch support. Each of the punches includes a plurality of punching heads. At least one punching head of each of the plurality of punching heads is shorter than the other punching heads. A multi-step punching sequence is therefore created such that no more than two slits of any of the joints of the sealless connection are simultaneously punched during creation of the sealless connection.

Abstract: A corrugation forming apparatus includes, as forming members, a rack tool assembled to a slide table and a pinion tool which rotates with rotation of a shaft. The apparatus also includes, as a displacement synchronization mechanism, a feed rack integrally assembled to the table and a feed pinion gear in meshing engagement with the feed rack. When a handle is rotated, its rotational force is transmitted to the feed rack via the feed pinion gear, so that the rack tool moves along the axial direction, and the pinion tool rotates in synchronism with the movement of the rack tool. This enables forming of successive recesses and projections on the thin metal plate, while reducing ductile cracks and warpage.

A container having toughness against internal pressure as high as that of cold forging is provided instead of gripping mechanism of a cylindrical material.

A component having internal teeth filling the container is obtained by enlarging outer diameter by spreading. It is desirable to provide in advance the same number of concave grooves as that of internal teeth to be formed, at equal intervals on an inner circumferential face of the cylindrical material.

Abstract: A process and apparatus for extruding aluminum into products, wherein aluminum logs are first heated to a predetermined temperature in a furnace, then are cut into billets of predetermined lengths, and then the billets, while still hot, are extruded into predetermined products in an extruder. In the process, the logs are cut into billets with a cross cut circular saw immediately after the logs are heated and before the logs are permitted to cool to a temperature below a suitable extruding temperature. The circular saw is cooled and lubricated during the cutting to as to restrain the saw from sticking in the heated aluminum and so as to maintain the temperature of the log at the cut within a predetermined range wherein the aluminum is relatively easy to cut and waste is minimized.
