Abstract:
An apparatus and method for hydroshearing and hydrotrimming for a hydroforming die includes a cutting insert fixed relative to the hydroforming die. The apparatus and method also includes a disposable insert fixed relative to the hydroforming die. The apparatus and method further includes a plunger movable relative to the hydroforming die to allow fluid within a tubular member to force a wall portion of the tubular member outward against the plunger and be sheared in the hydroforming die to trim the tubular member.
