A duct coupler assembly includes a female duct coupler, where the female duct coupler is coupled to a first duct segment. The female duct coupler includes a female duct coupler body having an inner surface having an inner diameter and a bayonet slot formed therein. The duct coupler assembly further includes a male duct coupler. The male duct coupler is coupled to a second duct segment. The male duct coupler includes a male duct coupler body having an outer surface having an outer diameter, where the outer diameter is smaller than the inner diameter of the inner surface of the female duct coupler body. The male duct coupler has a bayonet post extending from an outer surface of the male duct coupler body, and the male duct coupler body is positioned within the female duct coupler body such that the bayonet post is positioned within the bayonet slot wherein the male duct coupler is coupled with the female duct coupler.

A machine for bending oblong elements, preferably metal, includes a feed unit configured to feed at least one of the oblong elements along a longitudinal axis. A bending device is located downstream of the feed unit and a curving unit is disposed downstream of the bending device and is configured to curve the oblong element along part of its oblong development.
摘要:
Machine for working bars, suitable for working at least one bar having a mainly oblong development; the machine comprises at least two support sliders, of which at least one is mobile reciprocally toward/away from the other along an axis of movement and each provided with a work plane on which at least one curving unit is installed, suitable to curve at least a longitudinal portion of said bar, and at least a first bending unit, provided with a first contrast element having a first bending radius, and with a first bending element selectively rotatable about said first contrast element in order to bend said bar around the latter.
摘要:
Perfected curving machine comprising a support bench configured to simultaneously support one or more bars, wherein said support bench has an oblong development in relation to the length of the bars, and comprises at least one bending unit controllably mobile along the support bench in order to bend said bars, and clamping means configured to constrain the position of the bars on the support bench.

An apparatus for bending elongated members having different horizontal cross-sectional radiuses (e.g., different sizes of rebar) includes an extension portion, a first vise, and a second vise. The extension portion has a proximal region, a distal region, and a first aperture through the proximal region. The first vise has an aperture through the first vise. The second vise has a recessed region. The first aperture is sized to allow the extension portion to mount onto a vehicle hitch. The first vise and the second vise are located distally from the distal region of the extension portion. The aperture of the first vise is sized to accommodate an first elongated member having a horizontal cross-sectional radius (e.g., a first size of rebar). The recessed region of the second vise is sized to accommodate an second elongated member having a horizontal cross-sectional radius (e.g., a second size of rebar different from the first size of rebar). Accordingly, the horizontal cross-sectional radius of the first elongated member is different than the horizontal cross-sectional radius of the second elongated member.
摘要:
Bending machine to obtain shaped elements from pre-cut profiles, equipped with a drawing assembly which draws the profiles, first shearing means arranged downstream of the drawing assembly and bending means arranged downstream of the first shearing means. Downstream of the bending means are arranged second shearing means to eliminate the terminal segments of the profiles corresponding to the difference between the linear development of the shaped element to be produced and the length of the pre-cut profiles.
摘要:
An electric cutting and bending tool that transfers the rotation of an electric motor to an output shaft after slowing the rotation through a gear train. An eccentric cam is provided integrally with the output shaft and drives against a pivot plate. The pivot shaft has one end provided with a cam roller in rolling contact with the cam, another end provided with a movable blade and an intermediate portion provided with a pivot pin. A bending roller is provided on the cam to bend a reinforcing rod about a center pin to a desired angle between 0-180.degree..

A cutter/bender apparatus is provided for selectively cutting and bending a workpiece. The bending member includes a bending pin actuated by a hydraulic cylinder that moves the bending pin into and out of engagement with the workpiece to clamp the workpiece against a support plate. When clamped, another hydraulic cylinder lifts a movable bending member toward the workpiece, bending the workpiece about the bending pin in the process. The cutting member includes a fixed cutting member and a movable cutting member mounted in side to side abutment. The cutting members include a slot that extends laterally therethrough in which the workpiece to be cut is placed. The hydraulic cylinder that operates the movable bending member also provides motion for the movable cutting member. As the movable cutting member moves, it moves the aligned slots of the individual cutting members out of alignment, shearing the workpiece in the process. The cutter/bender apparatus may be attached to a loader vehicle using its hydraulic power for actuation or may include an independent power source. A carrier rack for the apparatus facilitates handling, positioning, and transport of the workpieces. Safety features, including a safety shut-off switch and a coupler member, incorporated into the apparatus make its use with a loader vehicle safer.
