A method of manufacturing a joined member where joining portions of at least two members are integrally formed with each other by press working thus joining said at least two members, the method comprises an engaging step, an inserting step, and a press working step.

A punch processing method for a laminated iron core includes sequentially feeding the steel sheets to a mold; and performing a plurality of processes in the mold, the plurality of processes includes fixing the steel sheets being stacked to each other at a first fixing part that is positioned outside a closed curved line corresponding to an outermost periphery of the laminated iron core and a second fixing part that is positioned in a portion that finally serves as the laminated iron core; and performing punch processing on the outermost periphery of the laminated iron core while the steel sheets are stacked.

Discussed is an electrode lead bending and welding apparatus including a base portion movable in a vertical direction and a horizontal direction, a bending portion attached to the base portion and extending away from the base portion, and a sensing portion attached to the bending portion and rotatable; . A welding between an electrode lead and a busbar of a battery cell is performed in the state in which the electrode lead is bent by the bending portion, . Also discussed is an electrode lead welding method using the electrode lead bending and welding apparatus.

A drive assembly for a torque converter is provided. The drive assembly includes a turbine shell and a damper assembly fixed to the turbine shell by at least one rectangular rivet. A method of forming a drive assembly for a torque converter is also provided. The method includes fixing a turbine shell and a damper assembly together by a plurality of rectangular rivets.

In the present invention, a through-hole (2) and a compression periphery part (3a) at which the core of the resin foam (1c) is compressed are provided in a fastening part of a resin-foam core composite plate (1). A cylindrical part (11a) of a metallic fastening member (11) is inserted into the through-hole (2) from the proximal end side of a wall part (4). The fastening member (11) is crimped to the distal end of the wall part (4) via an eyelet member (12) placed on the outside of the wall part (4) so as to forcibly spread the cylindrical part (11a). The fastening member (11) and a counterpart member (A) are fastened together by tightening a nut (14) onto a bolt (13) inserted into the cylindrical part (11a).

A riveting structure for a thin heat sink fin and a thin cover plate is disclosed. The riveting structure includes a plurality of thin heat sink fins and a thin cover plate. The top of each thin heat sink fin is provided with a raised portion, the thin cover plate is formed with a plurality of cover plate riveting holes, and the raised portion is pressed and deformed by a rolling device in a rolling manner to fill the space of a corresponding one of the cover plate riveting holes, thereby fixing the raised portion. It is suitable for a “thin” design, improves the assembly efficiency greatly, reduces the labor cost, and reduces the product defect rate effectively.

A rigid sheet blank includes a first section configured to be bent about a first axis and a second section configured to be bent about a second axis. The first section has a peripheral edge and at least one tab extending from the peripheral edge. The at least one tab is bendable by hand. The second section defines at least one opening configured for receiving a respective one of the at least one tab during bending of the rigid sheet blank.
