A pilot assembly and method has a cylindrical pilot body with a tapered outer end, a grooved inner end, and a central portion with at least one inwardly curved side wall relief, as well as internally mounted reciprocating ejector pins with outer ends that protrude through holes in the outer body end to strip stock from the pilot. A spring has its outer end mounted in the groove in the outer body end, and an inner end attached to the inner body end in a pre-tensed condition. A cap screw has an enlarged head that has at least a portion thereof fit into the pilot sidewall relief, and a threaded shank that anchors the pilot in an associated die member.

Provided is a door for a refrigerator. The door includes an outer door manufactured by pressing and deforming a metal sheet. The outer door includes a first surface, second to fifth surfaces extending from the first surface, and a plurality of flanges extending from the second to fifth surfaces. The first to fifth surfaces are integrated with each other and defined based on the pressing and deforming of the metal sheet. A door liner is coupled to surfaces of the plurality of flanges of the outer door, and an insulation material is disposed in a space defined between the door liner and the outer door.

A guided keeper assembly includes a base, at least one marginal fastener aperture to detachably mount the base to an associated die shoe, and a central guide aperture. A guide pin is closely received in the central aperture of the base. A first end of the guide pin has an enlarged head to positively limit travel between the die shoe and die pad, and an opposite second end with a generally flat terminal shoulder configured for close reception in a blind hole in the die pad. The shoulder has a fastener aperture at a location spaced radially offset from the central axis of the guide pin. A fastener extends through the fastener aperture in the die pad and engages in the fastener aperture in the second end of the guide pin to securely, yet detachably, connect the second end portion of the guide pin with the die pad.

An exchangeable plate is suspended on a top plate and held in a lower end position without force by a hydraulic clamps. In an upper end position, it is connected with force fit to, and re-detached from, the top plate as a function of a stripping operation of a scrap web from a V-ring pressure plate. The exchangeable plate is transferred from the lower into the upper end position by movement of a ram, and transferred from the upper into the lower end position by gravity. A sensing distance, adapted to the brake path of the drive system, is provided between the top plate and the exchangeable plate. A sensing device in the V-ring pressure plate outputs a signal to the computer for stopping the drive system and deactivating the hydraulic system. A. sensor detects premature movement of a pressure plate in the exchangeable plate.

A die apparatus includes a tip end part blanking punch which forms a tip end configuration of a belt-shaped sheet through a punch holding unit in an upper die. The punch holding unit includes a punch plate which holds the tip end part blanking punch, a punch plate moving mechanism which is lowered together with the upper die in a state where the punch plate is separated from the upper die when the tip end configuration of the belt-shaped sheet is formed, and holds the punch plate in a state where the punch plate is allowed to come near to the upper die when the punch plate is lifted, and an actuating mechanism which operates the punch plate moving mechanism in cooperation with a blanking or stamping operation of the upper die only when the tip end configuration of the belt-shaped sheet is formed.

A battery case for a pouch-type secondary battery accommodates an electrode assembly therein, and includes a first case, a second case configured to cover the first case, a cup portion provided in at least one of the first case or the second case and has a space formed to accommodate the electrode assembly, and a side portion formed along an outer circumference of each of the first case and the second case. The side portion includes a sealing portion sealed by bringing the first case and the second case into contact with each other. The side portion also includes an insulation failure-preventing portion formed between the sealing portion and the cup portion and configured to accommodates a sealing material melted in the sealing portion. A battery case shaping apparatus and a secondary battery manufacturing method are also provided.
