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.

A rotary bit configured to deburr and swage an end of a tube, comprising a first end configured to deburr and swage the end of the tube, and a second end configured to be secured to a rotary device, wherein the first end includes a plurality of blades that extend axially along the first end and radially outward from the rotary bit, the plurality of blades including a plurality of leading blades and a plurality of finishing blades, the leading blades configured to initially deburr and swage the end of the tube upon insertion of the rotary bit into the end of the tube, and the finishing blades configured to complete deburring and swaging of the end of the tube, the finishing blades extending radially outward from the rotary bit to a greater extent than the leading blades.

An arrangement for working a tube end includes: an operating cylinder with a piston displaceable along an longitudinal axis; and a tube mounting, a tool holder being provided at an end of the piston facing the tube mounting. The operating cylinder is provided as a tandem cylinder. At least two cylinder stages are offset along the longitudinal axis. The piston includes connected piston segments, each piston segment being allocated to a cylinder stage.

Methods for forming a pipe end for a pipe having an inner surface lined with a liner are provided, wherein the pipe is cut at an axial location to provide a first end having an initial inner diameter defined by an inner surface of the pipe; and a length of the pipe is expanded from the first end to form an upset, bell end where an inner diameter of the upset, bell end is larger than the initial diameter, thereby defining an annulus between the inner surface of the pipe and the liner. A clamp for limiting a pipe's movement during various operations is also provided.

In the present invention, in a piercing punch and a burring punch which are shaft members having a first axis line as the center axis lines and are provided so as to be movable along the first axis line, first, after prepared holes having the first axis line as the center axis lines with respect to the first wall portion and the second wall portion are formed using the piercing punch, burring holes having the first axis line as the center axis lines with respect to the first wall portion and the second wall portion are formed using the burring punch.

A mold tool generally includes a base, a die assembly, a tightening element, a threaded element, and at least one shaping cap. The base defines a cutout, a first threaded hole opposite to the cutout, and a second threaded hole. The die assembly, composed of a first module and a second module, can be inserted into a receiving space of the base. The tightening element can be screwed into the second threaded hole of the base to fix the die assembly in place. The threaded element can be screwed into the first threaded hole of the base. The shaping cap can be fitted at one end of the threaded element. The die assembly defines channels of various diameters each for holding a tube of a specific diameter. The shaping cap can urge one end of a tube held in the die assembly to form a specific type of flare.
