| 20090282886 | MULTIFUNCTION HYDRAULIC HEAD SUITABLE FOR BEING APPLIED TO MACHINES FOR BENDING AND FORMING METALLIC SHEETS - A multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles is equipped with carriages ( | 11-19-2009 |
| 20160250675 | BENDING APPARATUS AND BENDING METHOD FOR A PLATE-SHAPED METAL WORKPIECE | 09-01-2016 |
| 072309000 | With coacting movable tool | 2 |
| 20110120204 | WORKPIECE BENDING METHOD AND APPARATUS - A workpiece bending method of forming a final formed article that has two surfaces on opposite sides of an inclined area, in which an inclined area is made up of a first bend portion, a second bend portion, and a flat surface portion, includes: the workpiece holding step of cantilevering an end portion of the workpiece by a stationary die and a holding member; and the forming step of curving an area in the workpiece that corresponds to the flat surface portion by moving a movable die to the stationary die so that the movable die presses a free-end side of the workpiece, and then forming the first bend portion and the second bend portion, and unbending the area in the workpiece that corresponds to the flat surface portion of the inclined area, by causing the moving die to press the workpiece to the stationary die. | 05-26-2011 |
| 20140165687 | CLAMPING DEVICE FOR BENDING PRESS AND BENDING PRESS PROVIDED WITH THE SAME - A clamping device for a bending press includes a clamping die with a space formed therein, a clamping holder rotatably disposed within the space of the clamping die around a rotation shaft formed thereto, an upper cam block and a lower cam block respectively disposed within the clamping holder and slidable along the horizontal direction, and of which a cam slant surface is formed at a front side of the upper cam block and the lower cam block respectively, an upper clamping block and a lower clamping block contacting each cam slant surface of the upper cam block and the lower cam block, and clamping an end of a pipe disposed therebetween by sliding along a slant direction of the clamping holder, and a pressing unit selectively pressing the upper cam block and the lower cam block. | 06-19-2014 |
| 072310000 | Clamp rotatable about fixed axis (e.g., bending brake) | 4 |
| 20090241627 | Blade Material Bending Method and Blade Material Bending Device - A process of bending a strip-like blade member in the width direction, and that of bending the blade member in the thickness direction are caused to be continuously performed. A method includes: a step of bending the blade member in the width direction; and a step of, after the bending process, bending the blade member in the thickness direction. In the width-direction bending step for the blade member, the blade member is clamped by a pair of rotary press claws | 10-01-2009 |
| 20090308128 | A KINEMATIC SYSTEM FOR CLAMPING SEMIFINISHED PRODUCTS BY MEANS OF PRESSING FOR SHEET METAL SHAPING PANELLING MACHINES - A kinematic system of movement for the clamping/pressing unit of a semifinished piece, that is to say of sheet metal or the like, of panelling machines, the kinematic system comprising a frame on which a presser unit is hinged to a pin and which is free to make angular movements around the pin, the presser unit consisting of elements v fixed to a head supporting the upper presser tool, the presser unit being moved angularly by at least one connecting rod driven by a first lower crank, in which the presser unit is driven by a second upper crank, the first and second crank defining an articulated mechanism, for driving the punch-presser unit, with two degrees of freedom in sequence that can be activated independently or simultaneously. | 12-17-2009 |
| 20120006088 | BENDING DEVICE - A bending device is provided with a bending mechanism, a fixing table, an articulated robot, and a control unit. Control performed by the control unit includes a bending/movement control in which a workpiece is moved by clamping the workpiece by the bending mechanism and moving the bending mechanism by the articulated robot, and the workpiece is bent by the bending mechanism while the workpiece is being moved. | 01-12-2012 |
| 20160114370 | PLATE-LIKE-WORKPIECE TWISTING AND RETAINING APPARATUS, PLATE-LIKE-WORKPIECE TWISTING AND RETAINING METHOD, AND PLATE-LIKE-WORKPIECE TWISTING AND SHAPING METHOD - Provided are a highly-versatile plate-like-workpiece twisting and retaining apparatus, plate-like-workpiece twisting and retaining method, and plate-like-workpiece twisting and shaping method that can give a freely-chosen twisted shape or curved shape to a plate-like workpiece with a simple, highly-versatile configuration without having to prepare a die member and that can also be applied to an integral skin. A twisting and retaining apparatus includes at least two support points that are contactable with a first surface in a twisting range of a plate-like workpiece; a plurality of pressing points that are similarly contactable with a second surface in the twisting range and that flank a line connecting the at least two support points in plan view of the plate-like workpiece; and an advance-retract driving apparatus (support unit, pressing unit) that causes at least the support points or the pressing points to advance and retract in a thickness direction of the plate-like workpiece. | 04-28-2016 |
