  • Patent number: 4214333
    Abstract: A trim die system for trimming bolt heads or the like is disclosed in which a trim die is formed with a polygonal opening extending therethrough and providing cutting edges at the forward end thereof. The cutting edges are formed in the shallow recess in the forward end of the die, and are spaced back from a land which engages the tool to prevent contact between the cutting edges and the tool when operating without blanks. The land protects the cutting edges against damage and the structure provides increased die life. The tool is mounted for limited sliding movement and is biased toward an extended position. When the die first engages a blank supported by the tool, the tool moves back against the biasing force to reduce the initial impact on the cutting edges of the tool.
