Improved method and apparatus for interlocking hemmed together edges of inner and outer vehicle body panels with an improved interlock joint. The inner panel blank is draw stamped and provided with PLP holes in a stamping press. A plurality of conventional hardware components are then welded to the inner panel. Then interlock holes are formed by a piercing tool moving through the inner panel border from its outboard to its inboard side while the inner panel is held by clamps and PLP pins. The hole piercing punch thus leaves cold worked upset material slightly raised inboard, rather than outboard, around the pierced interlock hole margin. Then the inner panel subassembly is married to the outer panel and transferred to a hemming station and again precisely clamped and positioned by PLP pins, whereupon hemming press gates are operable for hemming the flange lip of the outer panel over the inner panel border. The final hemming steel of each gate carries staking punches that individually strike a precision registered portion of such hemmed lip to deform it into locking engagement with the associated interlock hole. The upset material is thus flattened and accurately worked into embedment into the interior surface of the hemmed flange lip, rather than into the interior surface of the outer panel, thereby avoiding creating read through problems on the outer panel.

A system and process for stamping parts having tolerances below 1000 nanometers. The inventive system and process is particularly suited for producing optoelectronic parts. The system includes a stamping press and one or a progression of stamping stations for supporting a punch and die.

The stamping station includes a shaft for rigidly guiding the punch to the die. The stamping press is capable of providing the punch with the necessary force to perform the stamping operations. The system includes an interface system for interfacing the force of the press with the punch, while simultaneously structurally decoupling the press from the punch.

A slider of the punch carry out unit is moved in the X-axis direction adjacent a punching section of the punch press machine before or after a plate material is punched into a punched product by a punch press machine. At the same time, a gravity center and a shape of the punched product are calculated and recognized on the basis of the manufacturing data. On the basis of the obtained gravity center and the shape of the punched product, the gravity center of the punched product is moved under the lift arm by the X- and Y-axis locating mechanism. Vacuum pads located just over the punched product are selected or discriminated. Then, the lift arm is lowered and the punched product is held by actuating only the discriminated vacuum pads. During this lift motion, it is preferable to bend one end of the punched product slightly upward to easily separate the punched product from the remaining flat plate material. After the punched product has been lifted, the punched product is moved horizontally away from the punch press, and is then lowered on the punched product supporting unit by releasing only the actuated vacuum pads. Since only the vicinity of the gravity center of the punched product is held by a minimum possible number of the vacuum pads, irrespective of the size and shape of the punched products, the number of the vacuum pads can be reduced.
