Cold formed product and method for making

Abstract

Described is a method of making a cold formed product. The method includes the steps of forming a rod in diameter of annealed steel. At least a portion of the rod is positioned in a cavity and end portion of the rod is impacted to form a bulge in the rod in the cavity. The bulge is cold formed with a die to form an opening through the rod at the bulge surrounded by a upset portion. The opening and upset portion supporting a fastener positioned through the opening.

What is claimed is: 
     
         1 . A method of a making a cold formed product comprising the steps of:
 a. forming a rod between 0.125 and 0.625 inch in diameter of annealed steel,   b. positioning at least a portion of the rod in a cavity and impacting end portions of the rod to form a bulge in the rod in the cavity,   c. cold forming the budge in the rod with a die to form an opening through the rod at the bulge surrounded by a upset portion as part of the rod to support a fastener positioned by the rod through the opening.   
     
     
         2 . The method of a making a cold formed product as claimed in  claim 1  comprising in addition the following step:
 d. bending the rod into a desired cold formed product. 
 
     
     
         3 . The method of a making a cold formed product as claimed in  claim 1  the opening cold formed in rod at the bulge is between 0.05 and 0.375 inch in diameter. 
     
     
         4 . The method of a making a cold formed product as claimed in  claim 1  the upset portion cold formed in the rod at the bulge is between 0.25 and 1.25 inches in diameter. 
     
     
         5 . The method of a making a cold formed product as claimed in  claim 1  the upset portion cold formed in the rod at the bulge is between 1.5 and 2.5 times the diameter of the rod. 
     
     
         6 . A method of a making a cold formed product comprising the steps of:
 a. forming a rod between 0.125 and 0.625 inch in diameter of annealed steel,   b. positioning at least two portion of the rod in a cavity or cavities spaced from each end portion of the rod and impacting end portions of the rod to form bulges in the rod in the cavity or cavities,   c. cold forming the bulges in the rod with at least one die to form openings through the rod at each bulge each surrounded by a upset portion as part of the rod to support a fastener positioned through each opening in the rod.   
     
     
         7 . The method of a making a cold formed product as claimed in  claim 5  comprising in addition the following step:
 d. bending the rod into a desired cold formed product. 
 
     
     
         8 . The method of a making a cold formed product as claimed in  claim 5  the opening cold formed in the rod at the bulge is between 0.05 and 0.375 inch in diameter. 
     
     
         9 . The method of a making a cold formed product as claimed in  claim 5  the upset portion cold formed in rod at the bulge is between 0.25 and 1.25 inches in diameter. 
     
     
         10 . The method of a making a cold formed product as claimed in  claim 5  the upset portion cold formed in rod at the bulge is between 1.5 and 2.5 times the diameter of the rod. 
     
     
         11 . A method of a making a formed product comprising the steps of:
 a. forming a metal rod,   b. positioning at least a portion of the rod in a cavity,   c. impacting end portions of the rod to form a bulge in the rod in the cavity,   d. flattening the budge in the rod and forming an opening through the rod surrounded by a upset portion at the bulge as part of the rod to position and support a fastener positioned by the rod through the opening.   
     
     
         12 . The method of a making a formed product as claimed in  claim 9  comprising in addition the following step:
 e. bending the rod into a desired shape. 
 
     
     
         13 . The method of making a formed product as claimed in  claim 9  where the rod includes first and second end portions and a bulge is formed near each of the first and second end portions; 
     
     
         14 . The method of making a formed product as claimed in  claim 9  where the opening is less than the diameter of the rod. 
     
     
         15 . The method of making a formed product as claimed in  claim 9  where the upset has a diameter at least approximately three times the diameter of the rod.
