Abstract: Presented are metalworking systems for forming metallic workpieces, methods for making/operating such metalworking systems, and battery module cell tabs bent by a multistage cluster-and-bend press. A metalworking system includes a grouping tool and a contouring tool that both align adjacent a workpiece support structure, such as a base plate of a battery module housing buttressing a stack of battery pouch cells. The grouping tool, which may include a first reciprocating plunger or plunger head, presses together a stack of metallic workpieces to thereby form a workpiece set having a first bend profile and a first length. The contouring tool, which may include a second reciprocating plunger or a pair of plunger fingers mounted on the plunger head, is attached to the grouping tool and bends the workpiece set to a second bend profile, distinct from the first bend profile, and a second set length, shorter than the first set length.

Abstract: The apparatus comprises a first working unit for unwinding a coil of conductor and providing straightened conductor, and a second working unit comprising a bending device arranged to bend the straightened conductor leaving the first working unit and a rotary table on which the bent conductor leaving the bending device is laid, whereby a set of turns is formed to make the superconductive coil. The rotary table is rotatably mounted about a stationary vertical axis. The bending device is mounted so as to be translatable both in a longitudinal direction coinciding with the direction of a longitudinal axis of the straightened conductor that is fed by the first working unit to the bending device and in a transverse direction perpendicular to the longitudinal direction. The first working unit is mounted so as to be translatable, along with the bending device, in the transverse direction only.

Abstract: A method for three-dimensionally bending a workpiece comprises feeding the workpiece by a feeding unit provided at an upstream side of the workpiece, supporting the workpiece by a supporting unit at a downstream side of the feeding unit, processing the workpiece by clamping the workpiece with a three-dimensionally movable unit that is provided downstream of the supporting unit, heating a local part of the workpiece in a temperature range which allows quenching to be performed, applying a bending moment to the heated local part of the workpiece by the three-dimensionally movable unit in association with the supporting position and/or the moving speed of the workpiece after the heating step, and rapidly quenching the heated portion. Even when a high-strength workpiece is bent, it is possible to effectively obtain a product having excellent shape fixability and uniform hardness distribution at low costs for wide application for bending sophisticated automobile parts.
