Abstract
A modular face plate for mounting swing frame roll clamp to a rotator reduces the cost of the face plate and simplifies hydraulic connections to the clamping rams.
Claims14
A unitary swing axis support for a swing frame clamp, said swing axis support comprising:
- (a) a base having a first edge, a second edge opposing said first edge and a third edge;
- (b) a first subframe mounting block projecting from said base distal of said third edge;
- (c) a second subframe mounting block projecting from said base and spaced apart from said first subframe mounting block toward said third edge;
- and
- (d) a third subframe mounting block projecting from said base and spaced apart from said second subframe mounting block proximate said third edge, a portion of said base and a portion of said third subframe mounting block defining an aperture extending between a first side of said third subframe mounting block proximate said third edge and an opposing second side of said third subframe mounting block more distal of said third edge;
- said base, said first subframe mounting block, said second subframe mounting block and said third subframe mounting block comprising a single unit.

A face plate for a swing frame clamp, said face plate comprising:
- (a) a first unitary swing axis support and a second unitary swing axis support, each comprising:
- (i) a base having a first edge, a second edge opposing said first edge and a third edge;
- (ii) a first subframe mounting block projecting from said base distal of said third edge;
- (iii) a second subframe mounting block projecting from said base and spaced apart from said first subframe mounting block toward said third edge;
- and
- (iv) a third subframe mounting block projecting from said base and spaced apart from said second subframe mounting block proximate said third edge, a portion of said base and a portion of said third subframe mounting block defining an aperture extending between a first side of said third subframe mounting block proximate said third edge and an opposing second side of said third subframe mounting block more distal of said third edge;
- and
- (b) a first plate affixed to said first swing axis support and said second swing axis support, said first edge of said first swing axis support and said second edge of said second swing axis support in abutment with a first edge of said first plate;
- and
- (c) a second plate affixed to said first swing axis support and said second swing axis support, said second edge of said first swing axis support and said first edge of said second swing axis support in abutment with a first edge of said second plate.

A swing frame roll clamp comprising:
- (a) a faceplate having a first surface and including portions defining a substantially central aperture, said face plate including:
- (i) a first subframe mounting block projecting from said first surface distal of said aperture;
- (ii) a second subframe mounting block projecting from said first surface and spaced apart from said first subframe mounting block and nearer to said central aperture than said first subframe mounting block;
- and
- (iii) a third subframe mounting block projecting from said first surface and spaced apart from and nearer to said central aperture than said second subframe mounting block;
- (b) an elongate subframe comprising a first flange and a spaced apart second flange, said subframe pivotally attached to said first subframe mounting block and said third subframe mounting block and arranged to pivot about an axis substantially parallel to said first face of said faceplate, said second subframe mounting block resisting displacement of said first flange in a direction of said central aperture of said faceplate and said first subframe mounting block resisting displacement away from said central aperture of said faceplate;
- (c) a hydraulic clamping ram pivotally connected to said subframe proximate an end of first flange and said second flange;
- (d) a revolving hydraulic connection affixed to said face plate in said central aperture;
- and
- (e) a hydraulic fluid conduit connecting said revolving hydraulic connection and said clamping ram, said conduit passing between said face plate and said second flange of said subframe through an aperture connecting a first side and a second side of said third subframe mounting block and defined by portions of said third subframe mounting block including portions offset from said first surface toward an opposing second surface of said face plate.
