An assembly for hot forming a component includes first and second location features reversibly attached to a sheet metal element that forms the component. The assembly is loaded into a high temperature forming rig by loosely locating the location features into corresponding datum features in a forming tool. As the assembly heats up, the location features locate accurately with the datum features. Thus, the assembly can be accurately located onto the tool accurately and with minimal opening of the hot forming rig, thereby improving efficiency and safety.

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.

Electromagnetic manufacturing method and forming device of mesoscale plate are provided. The manufacturing method includes: oppositely and parallelly disposing a first workpiece to be formed on top of a mold, side-press restraining two ends of the first workpiece, and disposing a deceleration block on two sides of the mold; controlling the first workpiece to tend toward the mold and to be deformed under the drive of uniform electromagnetic force; and colliding a middle area of the first workpiece firstly with the mold under the drive of uniform electromagnetic force, and driving the speed of the middle area of the first workpiece to decelerate to zero. When an area close to the two ends collides with the deceleration block and until the speed of all areas of first workpiece decelerates to zero, forming is completed. Shaping is tending further toward the mold through electromagnetic force until completely fitted to the mold.

The present invention discloses a method for synchronously processing dual belt materials. The method comprises steps of feeding, processing, detecting, assembling and outputting finished products. The step of feeding materials comprises cleaning, dividing materials, positioning and feeding. The step of assembling comprises pushing and assembling. A dual-belt-material feeder is used for feeding, and a dual-belt-material mould is used for punching. The dual-belt-material feeder (1) comprises a moving feeding device (11), a fixed feeding device (13) and two guide frames (14). The dual-belt-material mould comprises two punching moulds. The beneficial effects of the method for synchronously processing dual belt materials are that: the method can be used for producing thin wall miniature assembly parts in a single line and assembling the thin wall miniature assembly parts on line, so that problems caused by that the thin wall miniature assembly parts are produced in two production lines can be avoided.

A system and method for placing an object, which is to be processed on a production apparatus in a precise position, is provided. The system includes at least one location-determining system for determining a relative location of an object in relation to a production apparatus and a positioning apparatus for positioning the object on the production apparatus. The positioning apparatus has a receiving apparatus for receiving and discharging the object, and a movable arm for moving the object from one location to another.
