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.

A tapping sleeve includes a first bend line in a planar outlet band between a first side end and a second side end of the planar outlet band, the first bend line extending from a front end to a back end of the planar outlet band, a first outlet flange defined between the first side and the first bend line; a second bend line in the planar outlet band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar outlet band, a second outlet flange defined between the second side and the second bend line; and an arcuate portion formed between the first bend line and the second bend line.

A crimp coupling includes a crimping ferrule for connecting a hose to a fitting. The fitting includes an outwardly projecting stop collar and a groove which extends circumferentially around the fitting at a constant axial distance to the stop collar. The crimping ferrule, which can be slid onto the fitting, includes a flange, a tapering hinge section, and a cylindrical section. A distance between the stop collar and the groove of the fitting is dimensioned such that the flange, when abutting the stop collar, has a lower edge facing away from the stop collar above the groove. Due to a diameter reduction of the cylindrical section and the tapering hinge section, during crimping, the flange is pivoted such that the lower edge of the flange is turned into the groove by the pivotal movement of the flange.

A method for joining members according to the present invention includes: providing a first member, a second member, a guide shaft member, a rubber member, a first plunger, a second plunger, and a drive mechanism; inserting the second member into a hole portion of the first member; inserting the guide shaft member into a through-hole of the rubber member; inserting the rubber member, into which the guide shaft member is inserted, inside the second member; arranging an assembly in which the first member, the second member, the rubber member, and the guide shaft member so as to horizontally extend; arranging the assembly so as to be sandwiched by the first plunger and the second plunger; and moving the second plunger toward the first plunger; compressing the rubber member by the first plunger and the second plunger in a direction where the guide shaft member extends, and expanding the rubber member radially outside the guide shaft member; and thus expanding and deforming at least a portion of the second member that is inserted into the hole portion to join the portion to the first member by press-fitting.

Techniques for implementing and/or operating a deployment system that includes a vehicle frame of a deployment vehicle, a drive sub-system, which includes wheels secured to the vehicle frame, a swage machine, and a fluid power sub-system. The swage machine includes a grab plate, which interlocks with a grab notch on a pipe fitting to be secured to a pipe segment, which includes tubing that defines a pipe bore and a fluid conduit implemented in an annulus of the tubing, a die plate including a die, and a fluid actuator that actuates the grab plate toward the die plate to facilitate conformally deforming a fitting jacket of the pipe fitting around the tubing of the pipe segment. The fluid power sub-system selectively powers the drive sub-system or the swage machine based on a target operation to be performed by the deployment vehicle.

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. Additionally, the system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch on the grab ring to facilitate securing the pipe fitting to the swage machine, a die plate in which a die is loaded, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to push the die plate over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment via a forward stroke.

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. The system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch to facilitate securing the pipe fitting to the swage machine, a die plate including a die that opens away from the grab plate, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to move the die plate over the fitting jacket in an outwardly axial direction away from the grab plate to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment.

A method of manufacturing a plunger pump includes a temperature difference generation process of generating a difference in temperature with respect to a normal temperature state for either one of an outer cylinder or an inner cylinder, a cylinder insertion process of inserting the inner cylinder inside the outer cylinder in a state in which the inner cylinder has a smaller outer diameter than an inner diameter of the outer cylinder as a result of the temperature difference generated by the temperature difference generation process, an elimination process of eliminating the generated temperature difference, and a plunger placement process of placing a circular tube-shaped plunger in a pressure chamber of the inner cylinder so as to enable of reciprocating motion by the plunger.

A method for assembling a brazing ring on a return tube constituting a refrigerant passage of a heat exchanger according to an embodiment of the present disclosure includes performing a pipe shrinking process on a straight portion of the return tube, coupling the brazing ring on the return tube through a return tube assembly device, and performing a pipe expanding process on the straight portion of the return tube to which the brazing ring is coupled. The coupling of the brazing ring on the return tube is performed using the return tube assembly device.

A method of manufacturing a swaging tool includes forming a body of the swaging tool via additive manufacturing, forming a jaw of the swaging tool, and connecting the jaw with the body. Forming the body may include providing a portion of the body with a lattice structure. The portion may be internal and may not be externally accessible. Forming the body may include adding material to form at least one recess in an outer surface of the body. The method may include conducting a stress analysis. The at least one recess may be formed based on or according to the stress analysis.
