Rollforming machine

A rollforming machine for forming a component having a generally C-shaped cross section with a web, a pair of legs connected to said web, and a pair of lips connected to said legs, comprising:

• a plurality of rollforming stations comprising:
• a first rollforming station structured and arranged to form the lips of the component;
• a second rollforming station structured and arranged to at least partially form the legs of the component;
• and
• a third rollforming station comprising:
• a moveable support stand;
• a pivot plate assembly movably supported on said movable support stand for selective pivotal travel relative thereto;
• a first forming roll rotatably mounted to a first spindle for rotation about a first axis, said first spindle connected to said pivot plate assembly to provide for angular movement of said first forming roll relative to said support stand;
• a second forming roll mounted to a second spindle for rotation about a second axis that extends through a central aperture defined by said first forming roll, said second spindle moveably connected to said support stand to provide for movement of said second forming roll relative to the angular movement of said first forming roll;
• and
• a third forming roll rotatably supported by said support stand for movement therewith, said third forming roll located beneath said second forming roll and is rotatable about a third axis that is not parallel to said second axis.

A rollforming machine for forming a component having a generally U-shaped cross section with a web and a pair of legs connected to said web, comprising:

• a plurality of rollforming stations comprising:
• a first rollforming station structured and arranged to form the legs of the component;
• a second rollforming station comprising:
• a moveable support stand having a first leg and a second leg;
• a pivot plate assembly movably supported on said movable support stand for selective pivotal travel relative thereto, said pivot plate assembly having a first pivot plate pivotally coupled to said first leg of said movable support stand and a second pivot plate movably coupled to said second leg of said movable support stand;
• a first forming roll rotatably mounted to a first spindle, said first spindle connected to said pivot plate assembly to provide for angular movement of said first forming roll relative to said support stand;
• a second forming roll mounted to a second spindle that extends through a central aperture defined by said first forming roll, said second spindle moveably connected to said support stand to provide for movement of said second forming roll relative to the angular movement of said first forming roll;
• a third forming roll rotatably supported by said support stand for movement therewith;
• and
• a pivot stop connected to said movable support stand for contact with said pivot plate assembly to adjustably limit the pivotal travel of said pivot plate assembly.

A rollforming apparatus, comprising:

• an upstanding standing support stand;
• a lower forming roll having an axis and being supported on a lower forming roll shaft rotatably supported by said support stand;
• a pivot assembly supported on said support stand for selective pivotal travel relative to said upstanding support stand;
• an overbend roll rotatably supported on said pivot assembly for pivotal travel therewith;
• and
• an angled roll couple to an angled spindle extending through an opening in said overbend roll and movably supported on said upstanding support stand, said angled spindle oriented along an axis that is not parallel to said axis of said lower forming roll shaft.

A rollforming apparatus, comprising:

• an upstanding standing support stand having first and second upstanding legs spaced from each other;
• an adjustment block received between said first and second upstanding legs of said upstanding support stand;
• a first slide assembly coupled to said first upstanding leg and said adjustment block and a second slide assembly coupled to said second upstanding leg and said adjustment block, said first and second slide assemblies defining a path of angular travel of said adjustment block upon an application of a vertical force thereto;
• a lower forming roll supported on a lower forming roll shaft rotatably supported by said support stand, said lower forming roll having an outer circumference;
• an overbend roll rotatably and pivotably supported on said upstanding support stand, said overbend roll having an outer circumference and being oriented relative to said lower forming roll such that said outer circumference of said overbend roll is closer to said lower forming roll shaft than said outer circumference of said lower forming roll to define a corner area therebetween;
• and
• an angled forming roll mounted to a second spindle that is rotatably coupled to said adjustment block, said second spindle further extending through a central aperture in said overbend roll and being moveably connected to said support stand to provide for movement of said angled forming roll into said corner area.
