Abstract: A press brake die holder for holding a press brake die having an upper, work-contacting surface and a lower, elongated tang. The die holder has an elongated body having a slot defined by opposing walls, the slot being configured to receive the tang of the press brake die. One of slot walls has a cavity opening into the slot toward the other slot wall, and a resilient plug is received in the cavity and protrudes into the slot toward the other wall. As the tang is received in the slot, the resilient plug contacts and urges the tang resiliently into contact with the other slot wall to restrain the tang from wobbling in the slot.

Abstract: A displacement indicator device 10 for a press brake compensator 16 includes a first recess 20 in a lower wall of a preselected portion or a die holder member 14 of the press brake compensator 16, an indicator rod 18 snugly inserted into the first recess 20, a second recess 34 in a side wall 36 of a preselected portion of a wedge portion 38 of the press brake compensator 16, and a lifting cam 40 snugly inserted into the second recess 34. The indicator rod 18 is displaced by the movement of the preselected portion of the wedge portion 38. The indicator rod 18 displacement corresponds to the vertical displacement of the die holder member 14. An indicating scale 32 discloses the amount of displacement of the preselected portion of the die holder member 14 by aligning a reference mark 28 on the indicator rod 18 with a horizontal line and corresponding number on the indicating scale 32. The measuring of the vertical displacement of the die holder member 14, is ultimately used for the fast set-up of the press brake compensator 16 when a press brake is utilized to duplicate bends impressed upon substantially identical workpieces.

Abstract: Press brake tooling comprising a die and mating punch for bending sheet stock, the punch having an elongated, generally V-shaped punch tip and the die being of steel and having an elongated, generally V-shaped groove within which said punch tip is received during a bending operation. The V-shaped groove of the die has a floor and sidewalls that extend from the floor and terminate in edges that are spaced from each other across the width of the groove. The edges have surfaces that are configured to slidingly encounter the surface of a workpiece as it is bent between the tool and die. At least the die edge surfaces are nitrided or nitrocarburized to provide a slippery surface over which the workpiece slides during a bending operation, the edge surfaces having a hardness in the range of 52-70 Rockwell C with such hardness extending to a depth not exceeding about 0.06 inches.

Abstract: A bending method and bending apparatus directed to avoiding the risk of die breakage and damage to ram coupling parts due to an abnormal condition of a ram drive shaft and directed to achieving high-accuracy bending in which a uniform bend angle can be produced throughout the entire length of a workpiece without forming a boat-formed belly. In a press brake having three or more drive shafts, the deformation amounts of the ram and the table at each shaft-load imposed point are calculated based on input bending process data. A target closest distance between the punch and the die at each shaft-load imposed point is calculated from its corresponding deformation amounts. The difference between the actual bend angle of the workpiece after bending and a target bend angle is obtained at at least three positions, that are, the ends and center of the workpiece. From these differences, a correction amount for the moving amount of the ram at each shaft-load imposed point is obtained. Further, an adequate limit for the pressing force to be generated by each drive shaft is calculated based on the bending process data and the ram is driven by independently controlling each drive shaft so as not to generate a pressing force exceeding the set limit. To detect an abnormal situation due to abnormal movement of a drive shaft, a line connecting the positions of the drive shafts disposed at the points corresponding to the ends of the workpiece is obtained and the respective deviations of other drive shafts from the connecting line are obtained. If one of the deviations exceeds a preset allowable value, an abnormal situation is detected.

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 present invention provides a bending machine that enables an angle measuring instrument to be compactly built into a mold for accurate processing. The present invention also provides an operation method besed on learning control which achieves accurate bending with this bending machine taking spring back into consideration. A bending machine carries out bending using lineraly extending an upper die 4 and a lower die 2, the upper die 4 having a built-in angle measuring instrument 9. The angle measuring instrument 9 is composed of a corner contacting member 12 with links and an inductive linear position detector 13 for measuring displacement of the corner contacting member 12. In operation for learning, the position of and a load on the upper die 4 and a bend angle are measured during a bending process and a bend angle after spring back is subsequently measured. Based on the interrelationship between the measured values, a next correction value is obtained for an adjustable position of the bending machine which controls the bend angle.
