摘要： A draw stud assembly for use with a knockout punch tool having a movable piston, includes a connector attachable to the movable piston, a draw stud, and a quick connect mechanism. The quick connect mechanism includes mating first and second thread segments on the connector and the draw stud, respectively. The connector and the draw stud are movable between a first relative orientation where the mating first and second thread segments are misaligned to permit axial movement between the connector and the draw stud, and a second relative orientation where the mating first and second thread segments are aligned and engaged to inhibit axial movement between the connector and the draw stud.

摘要： A valve for selectively fluidly communicating a first fluid volume and a second fluid volume includes a valve body, an inlet orifice in fluid communication with the first fluid volume, and an outlet aperture in fluid communication with the second fluid volume. The valve also includes an activation member axially movable relative to the valve body. The valve is operable in a first mode in which the valve opens in response to manual actuation of the activation member. The valve is operable in a second mode in which the valve opens when a pressure difference between the first and second fluid volumes reaches a predetermined value, and the valve closes when the pressure difference between the first and second fluid volumes is less than the predetermined value.

摘要： A swage mechanism operable to expand an inner diameter of tubing including a housing defining a longitudinal axis, and a plurality of jaws coupled to the housing and movable radially outward relative to the longitudinal axis for selectively gripping an interior of the tubing. The jaws each include a first cam surface. The swage mechanism further includes a ram having a cylindrical portion and a frusto-conical head portion, and an arbor that is coupled to the housing and having a second cam surface. The frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing. The second cam surface of the arbor is engageable with the first cam surface of each of the jaws to move the jaws toward or away from the longitudinal axis, wherein the second cam surface moves in a direction along the longitudinal axis.

摘要： A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

摘要： A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a hydraulic assembly driven by the motor and including a reservoir containing hydraulic fluid, a secondary housing coupled to the main housing and defining a bore therein, a working piston moveable within the bore between a rest position and an actuated position, and a work zone defined between the secondary housing and the working piston into which pressurized hydraulic fluid discharged from the hydraulic assembly is received. One unit of fluid is added to the work zone to move the working piston from the rest position to the actuated position. The reservoir has a fill capacity no greater than about 1.5 units of fluid.

摘要： A balanced pump-axial piston pump for a hydraulic tool is provided. The balanced pump-axial piston pump includes a camshaft, cam followers, a lift block, a spring, a pump piston, a piston chamber, and a manifold. Rotation of the camshaft drives radial movement of the cam followers at the same time. The radial movement of the cam followers make the lift block move linearly along the axis of the hydraulic tool. The spring pushes the piston against the lift block so that the piston is kept in contact with the lift block. The linear movement of the lift block moves the piston linearly in the piston chamber, thereby pumping oil and providing hydraulic power.

摘要： Embodiments of the invention provide a pump assembly for a hydraulic tool. The pump assembly can include a reciprocating element that is configured to move between a retracted position and an extended position, a cam surface in the reciprocating element that can engage cam followers, a rotating element that can receive rotational input, and a base that can at least partially surrounds the rotating element. Movement of the cam followers along the cam surface can move the reciprocating element from the retracted position to the extended position.
