Apparatus and process for cutting of extruded material

Abstract

A rotating cutting apparatus comprising a cutting blade holder with at least one hole on the outside diameter of the cutting blade holder into which cutting blades are inserted and bonded to the cutting blade holder. The cutting blade holder encloses a center hole, so that the rotating cutting apparatus can be mounted to a drive shaft of machinery or secured to a cup that can be mounted to the drive shaft of machinery and driven by the machinery. The cutting blade holder can be made of a less expensive material, with only the cutting blade being made of higher-grade materials that maintains its cutting edge well. Additionally, in some arrangements of the present invention, the cutting blade may be sharpened on two sides so that the rotating cutting apparatus can be used for longer periods of time.

1 . An apparatus for cutting extruded materials comprising: 
 a generally cylindrical body adapted for rotation about its central axis;    a plurality of channels formed in the exterior of the body, the channels extending longitudinally and generally parallel to the central axis;    an adjustment member disposed and removably secured in each channel, wherein one end of the adjustment member extends beyond the end of the body; and    a cutting blade secured to the end of the adjustment member and extending transversely from the adjustment member, the cutting blade having a cutting edge.    
     
     
         2 . The apparatus of  claim 1 , wherein at least a portion of each cutting member is made of a material that is responsive to an inductive heating process.  
     
     
         3 . The apparatus of  claim 1 , wherein at least a portion of each cutting member is made of a material that has a co-efficient of thermal expansion less than 0.000007 inch/degree Fahrenheit.  
     
     
         4 . The apparatus of  claim 1 , wherein at least a portion of each cutting blade is forged.  
     
     
         5 . The apparatus of  claim 1 , wherein at least a portion of each cutting blade is cast.  
     
     
         6 . The apparatus of  claim 5 , wherein each cutting blade is formed of a carbide material secured to a substrate.  
     
     
         7 . An apparatus for cutting extruded materials comprising: 
 a body adapted to rotate about a first axis;    a plurality of channels formed in the body, wherein each channel includes: 
 a pair of generally parallel sides; and  
 a connecting side that is connected to each parallel side and having at least one arcuate edge; and  
   a plurality of cutting members, wherein each cutting member: 
 is secured in one of the channels;  
 has a holder; and  
 has a blade extending transversely from the holder.  
   
     
     
         8 . The apparatus of  claim 7 , wherein the body is generally cylindrical.  
     
     
         9 . The apparatus of  claim 7 , wherein at least a portion of each cutting member is made of a material that is responsive to an inductive heating process.  
     
     
         10 . The apparatus of  claim 7 , wherein at least a portion of each cutting member is made of a material that has a co-efficient of thermal expansion less than 0.000007 inch/degree Fahrenheit.  
     
     
         11 . The apparatus of  claim 7 , wherein at least a portion of each cutting member is forged.  
     
     
         12 . The apparatus of  claim 7 , wherein the blade is brazed to the holder.  
     
     
         13 . The apparatus of  claim 12 , wherein each blade is formed of a carbide material secured to a substrate.
