摘要： A device and a method are provided for shaping sheet metal. The device is provided with a plurality of support and clamping elements which are designed to cooperate with one another so as to clamp the sheet metal for a shaping process by mechanically contacting the sheet metal and by holding, orienting, and/or positioning processes. A plurality of actuators are designed to orient and/or position the plurality of support and clamping elements. A controller for the actuators is designed to control the plurality of actuators for adjusting the orientation and/or position of the support and clamping elements.

摘要： The present invention relates to a forming and manufacturing method of a bicycle shock-absorbing front fork crown. It mainly includes a stamping step that processes and forms an aluminum ingot base material into a crown prototype, wherein the crown prototype includes two shoulders and a solid convex seat, a deep drawing forming step that the solid convex seat is extended and processed to form a front fork tube, an appearance processing step that the front fork crown is formed through processing and forming the two side shoulders and the front fork tube surface, and finally, a drilling process is carried out on the two side shoulders. In this way, the front fork crown with the front fork tube can be formed integrally with an aluminum ingot through a series of processing processes, so that the front fork crown can provide a high-strength anti-vibration function.

摘要： A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.

摘要： Flanges formed on sheet metal parts to increase the part stiffness or create mating surface for further assembly are created in an incremental sheet forming process using forming tool and supporting tool that move along a specified tool path so as to gradually deform a peripherally-clamped sheet metal work piece into the desired geometry. With two universal tools moving along the designed toolpath on the both sides of the part, the process is very flexible. Process time is can also be reduced by utilizing an accumulative double-sided incremental hole-flanging strategy, in which the flange is formed in only one step.

摘要： Systems and methods for forming a workpiece are disclosed. The system may include a fixture assembly for receiving a workpiece having opposing first and second surfaces, first and second tools, and a vibration source configured to vibrate the first and/or second tool. The first and second tools may be configured to move along first and second predetermined paths of motion as the first and/or second tool is vibrated by the vibration source and may exert force on the first and second surfaces to form the workpiece. The method may include vibrating a tool using a vibration source and moving the vibrating tool and another tool along first and second forming paths to form the workpiece. The vibration source may be an ultrasonic transducer and may vibrate the tool at a frequency of at least 1 kHz.

摘要： A system includes a frame configured to hold a workpiece and first and second tool positioning assemblies configured to be opposed to each other on opposite sides of the workpiece. The first and second tool positioning assemblies each include a toolholder configured to secure a tool to the tool positioning assembly, a first axis assembly, a second axis assembly, and a third axis assembly. The first, second, and third axis assemblies are each configured to articulate the toolholder along a respective axis. Each axis assembly includes first and second guides extending generally parallel to the corresponding axis and disposed on opposing sides of the toolholder with respect to the corresponding axis. Each axis assembly includes first and second carriages articulable along the first and second guides of the axis assembly, respectively, in the direction of the corresponding axis.

摘要： An aerodynamic component of a gas turbine engine is provided and is fittable to a shell having a shell shape. The aerodynamic component includes a body having a component shape initially deviating from the shell shape prior to an assembly operation in which the aerodynamic component is to be fit to the shell. Deviation of the component shape from the shell shape aids in an establishment of a final desired shape of the aerodynamic component following the assembly operation.

摘要： A method and apparatus for processing fuselage sections. A first fuselage section is held in a cradle system. A current shape of the first fuselage section in the cradle system is measured. Forces to change the current shape of the first fuselage section to a desired shape for connecting the first fuselage section to a second fuselage section are identified. The forces identified are applied using a system to change the current shape of the first fuselage section towards the desired shape.
