Abstract: The invention relates to a forming tool (6) for construction member areas (2), comprising a forming device (10) and a fixing device (8), with which the construction member area (2) to be formed can be fixed relative to the forming device (10). In addition, it relates to a method in which a construction member area (2) is arranged relative to a forming device (10). The device is characterized in that the forming device (10) has a movable arrangement of individually activatable guide elements (26) with shaping bodies (30), it being possible, when a force is applied to the guide elements (26), for the shaping bodies (30) to be pressed in a positively driven manner into the construction member area (2) in such a way that plasticization extending completely or partly over the construction member thickness can be produced by means of the pressing operation, while the construction member area (2) is secured frictionally by the fixing device (8).

Abstract: A drilling tool includes a tool head having at least one chip groove and a tool shank. A slotted sleeve is placed on the tool shank and closely surrounds the chip groove. The edges adjacent the slot lie on solid material of the tool shank. The chip grooves and the sleeve form channels for carrying away the chips removed at the workpiece machining base. Owing to the slot, the sleeve can be gently spread apart and pushed onto the tool shank from the end having the enlarged tool head.

Abstract: A device for machining of workpieces or objects, comprises an elongated tool which rotates about its longitudinal axis and is provided with a shaft which can be coupled to a drive unit and with a chip-removing head connected to the shaft. In order to ensure that even a very long tool can be used in deep hollows in the workpiece in a stable and vibration-free way, a sleeve positioned between the shaft and the chip-removing head is connected at one end to the chip-removing head so that it cannot slide or rotate. The tool can be clamped in the chuck of a hand-held drive unit, preferably with a suction and flushing device connected in series, and used to suck away chips through the cavity in the sleeve and to pump cooling fluid onto the cutting site.

Abstract: A cutting tool for making cylindrical bores includes two or More cutting inserts and radially or approximately radially directed blades which leave an uncut core, as well as chip removal devices extending in the axial direction of the tool. The cutting tool is composed of at least two coaxial parts. One part forms the boring crown with the cutting inserts, and the other part forms the support for the boring crown with a clamping shank. The chip removal devices extend axially along both parts and lead radially to the outside.

Abstract: A machine tool is received in a structure that is carried along with the tool and has a sleeve extension which will be received in a tapered element with radially spreadibly tongues having end beads which will lodge behind a shoulder in teplate thereby positioning and clamping the tool; the receiver is additionally urged against the template and the tool by a piston cylinder drive.

Abstract: A device for bending or levelling workpieces by means of shot peening is improved by controlled impacting and indenting using a support element having a rear wall and side walls; a plurality of force spaced apart distributing elements are arranged in the support element and in the least one layer so that at least some of them abut the rear wall of the support element; a plurality of indenting, shot peening elements in engagement with at least some of the force distributing elements in that any of the shot peening elements engage at least two of the force distributing elements; there are elements of one of the plurality which abut the side walls of the support element.

Abstract: A device for the bending and deformation of panels such as skin elements for covering cells of vehicles in the aerospace industry such as aircraft, rocket space vehicles or the like, the skin elements having inwardly directed stiffening ribs which intersect in nodes; the device has first and second deforming members being capable of engaging the skin element in points adjacent to nodes under consideration of length changes obtained by some of the ribs; the two deforming members are adjustable in relation to each other and other through a variable armature mount such that the deforming forces respectively provided into the part to be deformed are oriented in the area of the nodes transversely or nearly transversely to those ribs which extend transversely to the curvature to be obtained and consistently tangentially to the panel part in the direction of curvature and following change of curvature on account of bending; and the direction of force action as provided by the deforming members into the work part is

Abstract: A method is disclosed for bending panels which are provided with reinforcing stiffening ribs. The bending is caused by upsetting or elongating the ribs. Apparatus for carrying out the method also is disclosed and includes means which engage the ribs at points spaced a predetermined distance from the panel skin. The invention is particularly applicable to the shaping of aircraft fuselage skin sections.

Abstract: This invention relates to an improvement in a hand drill with a pneumatically-hydraulically controlled advance and including a housing, a drilling drive unit adapted to be powered by compressed air and being displaceably guided in said housing by a piston and cylinder, and further including hydraulic lines, and control valves, the improvement comprising a rotatable support sleeve means secured to said housing and adapted to rest on the surface of a workpiece and surround a drill bit, said piston being a double-faced hollow advance piston means mounted in said cylinder so as to divide said cylinder into two chambers, one chamber together with one face of the advance piston means being adapted to be acted on by the compressed air, and the other chamber being adapted to be filled with hydraulic fluid and pressure-loaded by the other face of the advance piston means, said latter chamber communicating through hydraulic line means and a throttling back-pressure valve means with a cylinder means having a compensatin
