  • Patent number: 7114359
    Abstract: The invention relates to a method for producing bent spring rails from an endless spring band. The method is characterized by the following steps: continuous bending of a section of spring band; cutting the bent section of spring band into a spring rail; discontinuous reverse bending to reduce the internal stresses of the bent, cut-to-length spring rail by subjecting the spring rail to at least one reverse bending force and/or heat-treating the cut-to-length spring rails, the heat treatment being a low-temperature treatment in this case, preferably at a temperature of less than 200 *C.

  • Patent number: 6988390
    Abstract: A method of forming a tubular workpiece which consists in pre-bending a metal plate along at least two longitudinal lines of bend (12–13) then in bending the plate along at least one of the lines of bend (12–13) using a bending member (103–104) that exerts an external clamping force (F7, F8) along a part (23, 24) of the plate towards the at least one of the lines of bend (12, 13). Thereby preventing any sliding of part (23, 24) of the plate along the bending member (103–104) as the bending member bends the part. The bending member is articulated about a virtual geometrical axis (a, c) located inside a tubular section of the workpiece.

    Abstract: A method for the quality assurance of crimp joints on crimping devices, in which, based on a setpoint dimension of crimp force and/or crimp height, the actual value of crimp force and/or crimp height is measured continuously within defined upper and/or lower tolerance dimensions of crimp force and/or crimp height, and a corrected re-adjustment of crimp height is effected after the actual values have reach a correction value.

    Abstract: A bending machine for the bending of tube, rod and bar shaped workpieces (24, 24a) includes a machine base unit (2), a collet (6) for mounting a workpiece, and a tool assembly (15) with at least one bending tool. The bending tool can be opened and closed in the transverse direction of the workpiece by the relative movement of tool components to form a workpiece holder. The tool assembly (15) is mounted on a swivel support (10) to rotate around a tool axis of rotation (16) extending axially of the workpiece, and the swivel support (10) is mounted on the machine base unit (2) to be rotatable around a swivel support axis of rotation (11) extending in the axial direction (12) of the workpiece. The swivel support axis of rotation (11) and the tool axis of rotation (16), and the tool axis of rotation (16) and the workpiece holder, are radially offset relative to one another.

  • Patent number: 6550303
    Abstract: A die assembly for machines used to bend lengths of pipe for pipeline applications. The die assembly includes three major components, an exterior housing, a flexible die, and an eggcrate assembly. The exterior housing encompasses the flexible die and eggcrate assembly and pins into conventional bending machines. The flexible die includes a plurality of narrow plate segments positioned along a pair of tie rods. The plate segments are free floating and spaced so as to converge or diverge with respect to the direction of flex of the tie rods. The eggcrate assembly provides support for a plurality of spring plates. Each spring plate has a radius of curvature consistent with the amount of desired bend in the length of pipe.

  • Patent number: 6523389
    Abstract: A segmented pipe-bending die produces curvature across the pipe contacting surface of the die by varying the radii of the semi-circular pipe bending segments, or by offsetting the position of adjacent segments having equal or varying radii semi-circular apertures, laterally, longitudinally, or both. The pipe-bending die is formed from a plurality of metallic segments, which are affixed together. Each metallic segment of the die has a semi-circular pipe contacting surface portion. The radius of a plurality of the semi-circular pipe-contacting surface of each segment differs in length so that the pipe-contacting surface has a predetermined curvature formed by the resultant difference in height of the pipe contacting surface portions of each segment.

  • Patent number: 6298706
    Abstract: A pipe bending machine, a segmented bending die for use in a pipe bending machine, and a method for bending pipe are disclosed. The pipe bending machine includes a frame, a segmented bending die, a support structure, a stiffback, and a pin up shoe. A pipe is inserted in the pipe bending machine, over the pin up shoe, between the segmented bending die and the support structure, and onto the stiffback. By raising the stiffback upwardly and securing an end of the pipe with the pin up shoe, the pipe is bent against the segmented bending die. The segmented bending die and the support structure conform to the external surface contours of the pipe to support the walls of the pipe, thereby preventing distortion, buckling, flattening, or collapsing of the pipe during bending.

  • Patent number: 5481896
    Abstract: The present invention relates to an apparatus for bending a sheet die cutting knife to a specified shape, in which a knife is supported by a supporting mechanism and a clamping mechanism in connection with the upper face of the surface plate and bent by a bending mechanism in which the edge portion of the bending die which constitutes the bending mechanism is brought into contact, through vibrations and drive, with the knife side opposite to the direction along which the knife is about to be bent, by alternatively repeating a specified staying time and knife feeding time by the knife feeding mechanism every time such a bending process is carried out. This makes it possible to bend the knife to various shapes by properly changing the operating time of the bending mechanism and the feeding mechanism with a control device.
