Tubular joint roll forming machine
A roll forming machine for continuously forming a sheet into a joint section of a tube may include a plurality of roller stations arranged longitudinally on a frame and configured to bend the sheet to form the tube, and a carriage slidably secured to the frame. A pleat die assembly may be mounted on the carriage and can be configured to repeatedly engage the tube to form a series of pleats thereby bending the tube to form the joint section. A crimp die assembly may be mounted on the carriage and can be configured to engage the tube to crimp an end of the joint section and sever the end of the joint section from the tube. The carriage may be configured to be selectively moved relative to the frame while the tube is engaged with at least one of the crimp die assembly and the pleat die assembly.
DOUBLE PIPE AND METHOD FOR MANUFACTURING SAME
A double pipe includes an outer pipe in which an inner pipe is placed, and a spacer that maintains a clearance between the inner pipe and the outer pipe. At least a part of the spacer is press-fitted by an inner circumferential surface of the outer pipe and an outer circumferential surface of the inner pipe. More specifically, the outer pipe includes a diameter-reduced portion having undergone diameter reduction by plasticity processing. An inner circumferential surface of the diameter-reduced portion is present across the entire circumference other than the opening of the spacer, and presses an outer circumferential surface of the spacer inwardly in the radial direction.
Pinned head swage tool
A swage tool includes a first die coupled to a portion of a head and a second die coupled to a portion of a die block. A die block holder holds the die block and the second die. A piston inside a cylinder moves the second die toward the first die. At least two pins couple the head to the die block holder. When one of the pins is coupled to the head and to the die block holder, the head rotates about an axis transverse to a longitudinal axis of the cylinder.
Crimp tool force monitoring device
A crimp tool includes a frame, a lead screw and a nut assembly connected to the lead screw. A spring member is connected to the frame and movable with rotation of the lead screw. A first transducer is connected to the nut assembly to measure a first force applied on the nut assembly. A second transducer is connected to the spring member to measure a second force applied thereon by the spring member.
Tube connector crimping tool
A tube connector crimping tool is configured to enable a user to crimp a first refrigeration tube having a first connector cap to a second refrigeration tube having a second connector cap with one hand. The tube connector crimping tool has a first handle arm joined to a first handle head. A clamp head tongue is joined to the first handle head and clamp head teeth. a gear IS immediately adjacent to the clamp head teeth and joined to a ratchet. A second handle head is joined to the ratchet and a second handle arm. Squeezing the second handle arm toward the first handle arm crimps the first refrigeration tube to the second refrigeration tube.
Crimping apparatus for crimping prosthetic valve with protruding anchors
Embodiments of an apparatus, and a method for crimping expandable stents or prosthetic valves having a radially expandable and compressible annular body and one or more protruding anchors extending from the body using the apparatus, where the apparatus comprise a housing, a plurality of circumferentially arranged nesting jaws, and an actuator configured to move the jaws radially inwardly to reduce the size of the crimping aperture, thereby radially compressing the annular body of the prosthetic valve or stent. In particular embodiments, a selected set of the jaws, each having a front side and a recessed portion in its front side adjacent to its inner end. The recessed portions of the selected jaws collectively are sized and shaped to receive the one or more anchors of the prosthetic valve when the annular body is positioned within the crimping aperture.
Terminal Locator For A Hand Tool
A terminal locator for a hand tool includes a base, a magnet, and a holder attached to the base and rotatable with respect to the base between an open position and a closed position. The holder has a magnet passageway and a resilient latch retaining the magnet in the magnet passageway.
Clevis Pin Arrangement for a Tool
Embodiments of the invention provide a clevis pin arrangement for use in a tool. The clevis pin arrangement can include a clevis that includes a first and second leg with first and second apertures, respectively, a clevis pin that extends between the first and second apertures when in a closed position, and an actuator. The actuator can move the clevis pin arrangement between the closed position and an open position.
Hydraulic power tool
A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.
Crimping tool
A crimping tool is provided. The crimping tool includes a stationary jaw and a movable jaw. The movable jaw is arranged adjacent the stationary jaw, the movable jaw being movable from an open position to a closed position. A linkage is operably coupled to the movable jaw on one end, the linkage rotatable about an axle. A first input member is operably coupled to the linkage to rotate the linkage about the axle, the first input member rotating about a first axis. A second input member is operably coupled to the linkage to rotate the linkage about the axle, the second input member rotating about a second axis, the second axis being substantially perpendicular to the first axis.
