An automatic unloading, clamping and molding device for galvanized iron tubes and a manufacturing method thereof are used to position at least a crude pipe sleeve at a material strip and drive the crude pipe sleeve to pass through a positioning segment, a molding segment, a reshaping segment and unloading segment in a molding device for development of a plurality of graspable claw portions on the sleeve wall of the crude pipe sleeve and mass-production of stable-quality and low-manufacturing-cost pipe sleeves, each of which has a plurality of graspable claw portions.

A rotary crimping tool assembly includes a tool housing defining a crimping chamber, and one or more crimp wheels within the crimping chamber. The crimping chamber is configured to receive the portion of the structure in proximity to the crimp wheel(s). The crimp wheel(s) are configured to be pressed into and rotated relative to the portion of the structure to form one or more crimps in the portion of the structure.

A pipe assembly includes an inner pipe member and an outer pipe member that is externally fixed to an end portion of the inner pipe member. The inner pipe has a thickness that is less than that of the outer pipe which is placed outside the end portion of the inner pipe member. An additional fixture member is placed outside the portion where the inner and outer pipes are fitted to each other. While the inner pipe, the outer pipe, and the additional fixture are in this state, an electromagnetic coil is placed inside the inner pipe at a position where the outer pipe and the additional fixture are to be fixed. The diameter of the inner pipe increases by applying a pulse current to the electromagnetic coil. The diameter of the outer pipe increases by the action of force applied when the diameter of the inner pipe is increased.

Hydraulic crimp tools, working heads for hydraulic crimp tools and die sets for crimping wire connectors onto electrical conductor wires using such hydraulic crimp tools are provided. The die sets include identical dies that can be repositioned on the working head to mechanically securing wire connectors to an electrical conductor wire or a bundle of electrical conductor wires from different orientations.

A swage mechanism operable to expand an inner diameter of tubing. The swage mechanism includes a housing defining a longitudinal axis, a plurality of jaws coupled to the housing and movable relative to the longitudinal axis for selectively gripping the tubing, and a ram including a cylindrical portion and a frusto-conical head portion. The frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing.

The present invention relates to a sliding sleeve connection (6) between an expanded end (8) of an all-plastic pipe (7) or of a plastic composite pipe and a connecting element (1), which comprises an expanded end (8) of an all-plastic pipe (7) or of a plastic composite pipe; a connecting element (1) having at least one support body (2, 2a) provided with circumferential external ribs (3, 3a, 3b), onto which the expanded end (8) of the all-plastic pipe (7) or of the plastic composite pipe (7) is slid, and at least one circumferential collar (5, 5a); and a sliding sleeve (9) made of elastically deformable polymer material axially slid onto the expanded end (8), wherein the connecting element (1) comprises a pre-stop (4, 4a) between the circumferential collar (5, 5a) and the nearest circumferential external rib (3b) to the latter, and said pre-stop (4, 4a) constitutes a limitation for sliding onto the end of the pipe (8), wherein the end of the sliding sleeve (9) facing the circumferential collar (5, 5a) protrudes beyond the end of the pre-stop (4, 4a) facing the circumferential external rib (3b).

A combination of roller tools is used to cold work a pipe element and impart a desired shape to the sidewall. The roller tools are movably mounted on a frame. Segments of the roller tools align with one another during operation. The roller tools are used in a method of roll forming wherein the sidewall of the pipe element is compressed between the rollers.

A crimper analyzer system is disclosed. The crimper analyzer system also includes a network interface. The crimper analyzer system also includes a memory storage. The crimper analyzer system also includes one or more processors configured to: receive hose specifications and fitting specifications from the network interface, generate crimp parameters based on the received hose specifications and crimp operation data, obtain additional crimp operation data for a hose assembly operation, update the crimp operation data with the additional crimp operation data and store in the updated crimp operation data in the memory storage, and generate a unique assembly identification (UAID) for the hose assembly operation subsequent to the hose assembly operation.

Die sets and tools using such die sets, are described which promote axial alignment of the dies during die closure. In addition, jaw sets for tools are described that promote axial alignment of the jaws during die closure. Also described are related methods using the die sets and/or tools with such die sets.
