Abstract
A skiving apparatus for simultaneously skiving the outer and inner surfaces of an end of reinforced hose. The apparatus comprises an outer diameter cutting tool, an internal skiving mandrel and a bracket for holding the outer diameter cutting tool and the internal skiving mandrel in a substantially perpendicular relation. The internal skiving mandrel has a nose for coaxially receiving a hose end thereover, spiral cutting threads and a stop collar. To achieve the desired simultaneous skiving effect, the internal skiving mandrel and the outer diameter cutting tool have a coincident cutting direction. Thus, when the hose is fed over the mandrel and the apparatus is rotated the simultaneous skiving of the inner and outer surfaces of the hose is accomplished.

A skiving apparatus, comprising an outer diameter cutting tool, an internal skiving mandrel and a bracket for holding the outer diameter cutting tool and the internal skiving mandrel in a substantially perpendicular relation, the internal skiving mandrel having a nose for coaxially receiving a hose end thereover, spiral cutting means for screwing into an inside wall portion of the hose end and cutting the inside wall portion to obtain a desired cylindrical ring section, and a stop collar, the internal skiving mandrel and the outer diameter cutting tool further having a coincident cutting direction whereby when the hose is fed over the mandrel and either the hose or the apparatus is rotated a simultaneous skiving of the inner and outer surfaces of the hose is achieved and whereupon when the hose end is retracted, the desired cylindrical ring section is pulled out.
An internal skiving mandrel for use with an outer diameter cutting tool and bracket assembly, the internal skiving mandrel having a nose for coaxially receiving a hose end thereover, spiral cutting means for screwing into an inside wall portion of the hose end and cutting the inside wall portion to obtain a desired cylindrical ring section, the spiral cutting means having a cutting direction coincident to that of the outer diameter cutting tool, a stop collar, and bracket mounting means for holding the internal skiving mandrel securely within the bracket assembly in a substantially perpendicular relation to the outer diameter cutting tool.
