Abstract

A hydraulic drive tool such as a crimping apparatus which includes a crimp head assembly and a body portion which are arranged in an axially elongated configuration to balance a grip area of the apparatus along the center of gravity of the apparatus. The crimping apparatus includes a hydraulic drive assembly having a wobble plate. The hydraulic drive assembly has an axially oriented piston arrangement in a hydraulic head to position an axially arranged configuration of the hydraulic drive assembly along a central axis of the apparatus. The wobble plate is configured to provide axially displaced, non-rotational, generally linear movement of a wobble ring to transfer reciprocal movement to pistons retained in the hydraulic block. The apparatus is configured with the hydraulic drive assembly centrally positioned in the body portion with the crimping head assembly at one end and a battery power source at an opposite end. The apparatus provides a retract device which automatically operates to retract a hydraulic ram of the crimp head assembly a predetermined distance. The crimping apparatus provides a method of crimping which allows the operator to place the apparatus on a crimp article, crimp the article, automatically activate the retract device to disengage the head from the formed crimp, reposition the crimp head in a subsequent location for crimping and activate the apparatus to produce the next crimp.
