A tray bender allows a user to easily and efficiently bend a tubing tray or similar item. The tray bender includes a shaft and a tray-bending head. The shaft is an elongated, tubular structure which acts as a gripping element of the tray bender. The tray-bending head is a specifically designed structure which is used to engage the tray bender with a tubing tray or similar item. The user can apply an input force onto the end of the shaft opposite to the tray-bending head in order to provide a torque force to bend a tubing tray or similar. The tray-bending head is designed with prong-like structures with a gap space in between each prong-like structure to receive a tubing tray or similar item.

A tool for repairing an interior surface of a conductor tube comprises an elongate body having a proximal end and a distal end. The tool includes a profiled end surface that mates into the interior surface of the conductor tube. The tool includes a central protrusion that extends from the profiled end surface for aligning the tool within the internal passageway of the conductor tube. An imparted force is exerted on the proximal end and the force reshapes the interior surface of the conductor tube around the profiled end surface.

A method for chamfering the installation position of a water control valve of a faucet body, mainly using a punching machine to drive a processing punch to punch a first end or second end, where the processing punch is provided with a fillet corresponding to the hole of the first end or second end, which squeezes the burrs through the driving of the punching machine, allowing the surface of installation position of the water control valve to be even and smooth, achieving smooth rotation of the water control valve, and preventing the water stop rubber to be scratched by the burrs or sharp corners.

An apparatus for trimming a sheet metal panel in a die set. A grinding tool including a grinding wheel driven by a rotary drive is used to grind away a shear affected zone from the trimmed edge formed by the trim steel. The grinding tool is disposed within a cavity defined by the reciprocating die and is oriented to grind away a shear affected zone as the reciprocating die moves the grinding tool into engagement with the trimmed edge.

A long formed article made of one steel sheet includes a top sheet portion, a standing wall portion, and a protrusion portion formed in a portion of the top sheet portion by overlapping a portion extending toward an outside from each of both ends of the top sheet portion and a portion extending toward the outside from an upper end of the standing wall portion, in a non-protrusion region, a recessed part is formed in the top sheet portion, and a total value ? of inner surface peripheral lengths of the top sheet portion and the standing wall portion in a cross section of the formed article in a protrusion region and a total value ? of inner surface peripheral lengths of the top sheet portion, the standing wall portion, and the recessed part in the cross section of the formed article in the non-protrusion region satisfy 1.01??/??1.50.

An arc welding apparatus includes a conductor tube assembly that has a collar assembly with a collar body that is biased by a spring. A consumable assembly is mechanically secured to the conductor tube and displaces the collar body and the collar body imparts a biasing force against the consumable assembly pretensioning the consumable assembly on the conductor tube assembly.

The present invention provides an apparatus and a method for detecting a piping alignment using image information and laser sensors capable of precisely and accurately measuring and aligning the alignment of the entire pipes. The apparatus includes: a fixed plate installed on a base stage and having a reference pipe located thereon; a movable plate installed on the base stage along three axes to face the reference pipe and has an aligning pipe located thereon; a circular stage installed between the reference and aligning pipes and is configured to rotate and move along three axes so as to detect levelness and deformations of the reference and aligning pipes; a laser sensor and an imaging device installed on an upper side of the circular stage; and a controller configured to control the laser sensor and the imaging device and determine an alignment of the aligning pipe.

A press fitting, including a tubular component and an end portion of the tubular component which can be compressed to make a connection. The end portion has an opening to receive a tube and a first region having an annular ridge to receive a sealing ring. A second region is arranged on the side of the ridge adjacent the opening and a third region is arranged on the side of the ridge remote from the opening. The overall wall thickness of the press fitting in the second region is increased at least in a section or sections in comparison with the wall thickness of the tubular component in the third region.
