Abstract: A fluid-cooled toolpack for cooling can-forming dies without allowing cooling fluid to contaminate or contact the cans or the interior of the can bodymaker during production. The fluid-cooled toolpack generally includes a chill plate that is biased with a spring into contact with a can-forming die. The chill plate may be generally ring shaped and include annular heat pipes to carry heat away from the can-forming die to a set of heatsink fins at the top of the chill plate. Cooling fluid, such as water or air, can be used to remove heat from the heatsink fins. The chill plate can also be used to preheat the can-forming die before the equipment is used if desired, since the heat transfer of the system is non-directional.

Therefore, an oil remaining between the end surface of the outer punch and the bottom surface of a workpiece is relieved to the outside of the forging punch by way of the groove, thereby enabling precise forging. Further, the forging punch has obviated additional processing, because no traces of the groove are marked on the workpiece after processing.

Abstract: A wheel shaping apparatus including a single cotter for expanding first and second dies circumferentially split into a plurality of first and second die elements, respectively. The single cotter is supported by a cotter supporting member at one end portion of the cotter and is also supported by a cotter guide at the other end portion of the cotter during shaping of a rim element.

In the case when ring-like members are provided around the first and second dies or when teeth are formed at sides of each first and second die element, formation of local deformations at gaps between two adjacent first die elements and between two adjacent second die elements is suppressed.

Abstract: A one piece improved weld washer designed for weldable attachment to dents and crevices during auto body repair work. The improved weld washer is comprised of an apertured elongated oval principal plate member in washer-like form affixed at one smaller curved end with a rectangular tab-like arm member useful for welding to dents in a car body. For best results, the tab-like arm member has a lengthwise helical bend. This helical bend positions the distal end of the tab-like arm member in a perpendicular plane to that of the principal plate member. The distal ends of the tab-like arm members can be welded into the lengthwise crevice or dent of the car body while the apertures in the principal plate members are aligned allowing simultaneous passage of one pulling rod. The pulling rod engages the lowest improved weld washer first, pulling all in sequence, until all are aligned equally and the dent removed. The improved weld washers are then easily removed from the welds by a rotational twist.
