Abstract: The invention provides a hydroforming apparatus for forming a length of tube. A hydroforming press includes an upper platen and a lower plate. A first die set is provided for forming a first lengthwise portion of the tube and a second die set provided adjacent the first die set which forms a second lengthwise portion of the tube. A first pivot acts between a first and second upper die so that the second upper die can be pivotally adjusted on the upper platen relative to the first upper die. A second pivot acts between a first and second lower die so that the second lower die can be pivotally adjusted on the lower platen relative to the first lower die. A die insert is provided having an upper die insert and a lower die insert that define upper and lower insert cavities that connect together the first and second cavity portions of the upper die set and the lower die set. This die insert is removably mounted as needed to accommodate the pivotal adjustment between the first and second die sets.

Abstract: Method of correcting a bending operation performed by a press brake, the bottom beam of which contains deformation compensation cylinders, in which a calibration nomogram is pre-recorded using very short calibration pieces, this nomogram establishing a correspondence between the forces measured at the side frames and the pressures applicable to the compensation cylinders in order to keep the bottom beam substantially straight. During a subsequent bending operation, pressure values resulting from this nomogram are applied to the compensation cylinders according to the forces measured at the side frames. A bottom dead center is recalculated by taking account of the deformation of the top beam, the deformation of the side frames, the actual length and thickness of the piece, and the spring effect.

Abstract: A three-dimensional stereoscopic diagram creator creates a three-dimensional stereoscopic diagram including a desired bending angle based on graphic information of a product. A major dimension displayer displays a major dimension, tolerance and the like with respect to the three-dimensional stereoscopic diagram. On the other hand, a test piece displayer displays a test piece of the same material proposed for use as the material used for producing the product. The test piece displayer carries out trial bending on the test piece. A bending angle after a bending load is removed is measured by a bending angle measuring device. A spring back amount setter calculates a spring back amount from a difference in bending angle between before and after the load is removed. A stroke calculator calculates a stroke value relative to the desired bending angle considering the obtained spring back amount. Actual bending is performed on a product piece using the calculated stroke value.

Abstract: The invention provides a method and an apparatus for determining the bending angle of a work piece to be bent by means of a bending apparatus comprising a punch member and a die member cooperating with the punch member. The die member is provided with at least two channels through which pressurized air is blown towards a leg of the bent work piece. For measuring the pressure in each of the channels, a plurality of pressure sensing devices is provided and connected to a common control and analyzing assembly. On the basis of the pressure values measured by the pressure sensing devices and with the aid of formulae, tables, three dimensional diagrams or with the aid of a neuronal network, the control and analyzing assembly calculates the bending angle.

Abstract: A support medium is capable of being read by a numerical control system of a bending machine. The support medium stores program instructions for searching, in a memory region storing at least one group of data, each containing bending conditions, a bend angle and at least one penetration depth, whether input data including a desired bend angle and bending conditions are stored in the memory region, in a same group of data. The support medium sends a signal to the bending machine so that the bending machine executes a bending according to the penetration depth included in the same group of data.

Abstract: An actual plate thickness and actual material constants are measured during punching before bending. The measured information is reflected on the bending, so that the bending is performed efficiently and accurately. Punching is carried out for each blank developed based on a nominal plate thickness and nominal material constants in blanking before the bending of a work W. Then, an actual plate thickness distribution and an actual material constant distribution of the work W are calculated based on various data containing a ram stroke and a pressure detected in the punching.

Abstract: At a time of executing a bending process of a work according to a cooperation between a punch and a die, a provisional stroke value for obtaining a predetermined angle is determined on the basis of a bending process condition. A test bending process is executed on the basis of the provisional stroke value, and a striking number required for striking the work until the predetermined angle is obtained is judged. Since a stroke value correction amount at a time of a main bending corresponding to the striking number and the predetermined angle is previously determined, a main bending process is executed by correcting to a stroke value at a time of the main bending by computing the corresponding stroke value correction amount on the basis of the stroke value correction amount at a time of the main bending process.

Abstract: As part of a process for bending workpieces (14), when the workpiece (14) is released from the upper die (8) and/or the lower die (10), the actual size of the bending angle (.beta.) is continually determined; from the actual size of the bending angle (.beta.) found, the change in it is determined and, as soon as the change in the actual size of the bending angle (.beta.) assumes a predetermined value, the actual size of the then existing bending angle (.beta.) is compared with the desired size. On a tooling machine for carrying out the method described, there are scanning elements (17,18) and a device (24) for determining the actual size of the bending angle (.beta.) that are parts of a device (19) for determining the change in the actual size of the bending angle (.beta.). The device (24) for determining the actual size of the bending angle (.beta.) is connected to a comparison device (32) for comparing the actual size of the bending angle (.beta.) to the desired size.
