  • Patent number: 5092152
    Abstract: An improved crimping machine for crimping fittings on high pressure flexible hose of the type having a pair of opposed anvils moveable between an uncrimp position and a crimp position. A split crimp cage with each half thereof attached to respective ones of the anvils is provided. The crimp cage retains a plurality of crimping dies axially slideable within corresponding cage slots that are arranged in a uniform circular pattern about the cage. The cage slots extend radially from a common central transverse axis. The improvement comprises the use of crimping dies having substantially the same radial length, and substantially flat anvil cam surfaces that actuate the crimping dies to move at a uniform rate during a crimping operation. To achieve the uniform rate of travel, the flat anvil cam surfaces are oriented at a predetermined angle relative to the corresponding crimping die radial axis.
