An actuating device for actuating a contractible element for a bending element of an industrial machine for bending metal elements comprises a lower component and an upper component apt to move relative to each other from a first position to a second position, the actuation device including a connecting plate configured to be connected to the lower component of the contractible element. A rack and pinion gear unit is also set out and includes a pinion having an axis, at least a first rack and a second rack actuated simultaneously by the pinion. The first rack is configured to be fixed to the upper component and the second rack is configured to be coupled to the connecting plate. The pinion is operable in a first direction of rotation to move the first rack and the second rack transverse to the axis in opposite directions. The pinion is operable in a second direction of rotation, contrary to the first one, to move the racks in opposite directions towards a second position.

A system for shaping a workpiece, which may be in the form of a structural framing component, includes a tool with first and second indenting blades for indenting the workpiece as driven by a blade control apparatus. The workpiece is supported at the tool by one or more workpiece support modules that are each selectively and removably securable to the tool. A base plate is provided at the tool for removably securing the workpiece support modules to the tool without having to detach the tool from a platform of substructure. The workpiece support modules may therefore be quickly replaced to coordinate with workpieces of various size and shape.

A roll stamping apparatus includes sets of rollers rotating while facing each other so as to press opposite surfaces of a material which is continuously supplied to move between the rollers; and molding portions having a stamping structure applied to outer surfaces of the sets of rollers so as to mold the material, wherein a plurality of sets of rollers are disposed in a movement direction of the material, the molding portions of the sets of rollers are formed to sequentially change a cross section of the material in the movement direction of the material, wherein at least one of the sets of rollers before a final set of rollers through which the material finally passes is a set of over-molding rollers having molding portions of which a length in a circumferential direction is longer than a length of the molding portions of the final set of rollers.

A method for forming large titanium parts includes forming bends into a titanium plate for form a bent part. The bent part is then roll-formed to form contours into the bent part. The surfaces of the contoured part are rough-machined, and the part is then secured to a bladed form fixture. The bladed form fixture comprises a plurality of header boards that secure the part to the fixture. The fixture part is placed in a thermal vacuum furnace and a stress-relieving operation is performed. The part is removed from the fixture and final machining takes place.

A formed sheet metal material and methods, tools and apparatus for forming the sheet metal material in which a pattern of projections and depressions are cold worked in a first portion and, simultaneously, indicia is embossed in a second portion of the sheet material. The cold worked portion is formed with the projections and depressions configured and distributed such that lines drawn on a surface of the formed sheet material between adjacent rows of projections and depressions are not rectilinear. The indicia is indicative of the alignment between the tools.

To provide a drawing-out tool for sheet metal which is less in failure and excellent in the durability and has excellent handling property by evading generation of trouble in an electric system by shielding dust, metal dust, soil dust or the like from mingling in or attaching to the electric system. The drawing-out tool for sheet metal comprises a center shaft (22); a first operation means (20) provided with a bit (25) arranged to an apex part of the center shaft; a second operation means (30) for pulling-up the first operation means; and an energization mechanism (100) for supplying electric current to the bit are provided. The housing (10) for accommodating the illumination unit (70) and the illumination unit for illuminating a sheet metal surface accommodated in the housing are included.
