The system utilizes a bottom bracket assembly/welding line, a two-press blank forming station and a wrapper final assembly system. The forming and assembly system synchronously links up a pre-formed wrapper blank and fully assembled bottom bracket to the wrapper line. Parts are automatically fed and welded to form an enclosed bottom frame. Simultaneously, two die sets and part transfer system emboss and edge form a wrapper blank. The blank is then transferred on to the wrapper line where it is formed into a "U" shape with corner radiuses and a large radius formed in the front panel. The bottom bracket is then welded to the wrapper and two corner brackets located and welded into place. Then the wrapper is transferred onto the final assembly line.

Programmable Servo Positioned Punching Station

This metal fabrication station features two independent servo positioned C frame presses. Each press is independently servo positioned in the Y direction to punch or form features along the edges of coil stock being servo fed in the X direction. The combination of fully programmable X-Y positioning as well as the interchangeable turret tooling provides easy-to-adjust flexibility and Demand Flow Manufacturing production capability.

Programmable Pierce and Forming Station

The Programmable Pierce and Forming Station consists of a tandem ram straight side hydraulic press. The press utilizes the two rams to pierce and form a family of features into the electrical enclosure. Both dies used in the tandem press are "Smart Dies", consisting of a number of automatically gagged punches that are activated depending on product recipe.

Programmable Shearing Station

The Programmable Shear is used to shear a finished blank from the coil stock. The shear is also used to shear off the rough leading end of the coil when starting a new coil as well as to cut the trailing end of a coil into manageable scrap pieces. An auxiliary pinch roll coil stock feeder is fixed adjacent to the shear to use when the trailing coil end has left the control of the main coil stock feeder.

Programmable Servo Positioned Wing Bend Station

The Wing Bend Station motion is servo programmable to adjust for variance in over bend requirements due to varying lengths of enclosure or for variations in mechanical properties between coils. If an adjustment is required either at the beginning of a coil change, at the point of product length change, or anywhere in-between, it is made "on-the-fly" by making an adjustment in the following part and then measuring that part for correction verification.

Smart Dies

Hess "Smart Dies" are sheet metal fabrication die sets where individual features are servo controlled to seamlessly activate on command from the system controller. This is accomplished by gagging punches and (or) varying the pitch of the material feed, which can change from part size to the next without stopping the press system or changing the die. Smart Dies have been most commonly used in HVAC, appliance and electrical enclosure sheet metal components.
