The present invention discloses a correction equipment for an end face of an aluminum alloy wheel, including a correction device and a transport device, which is configured to transport the aluminum alloy wheel to the correction device. The correction device comprises a rack body, which is provided with an oil cylinder on an upper part, a lower pressing plate on a middle part and a jacking air cylinder on a bottom part, with an output end of the oil cylinder fixedly connected downward to an upper pressing disc and an output end of jacking air cylinder fixedly connected upward to a lifting frame, on which a displacement roller way is provided. The present invention satisfies the need for an end face correction for an aluminum alloy wheel while having significant, stable and reliable characteristics.

The present disclosure is directed to remedying a non-conforming feature of an aluminum alloy part. A method may include identifying a yield strength as a function of temperature for a designation of the aluminum alloy part, determining a stress to be applied to the feature to re-form the non-conforming feature to within a dimensional tolerance, correlating the stress to the identified yield strength to determine a process temperature of the part upon applying the stress to the feature, determining a time duration for applying the stress to the feature at the determined process temperature, and applying the stress to the feature of the part, the feature being restrained to oppose the stress, while heating the feature to the determined process temperature, and maintaining the application of the stress and the heat to the feature for the time duration in order to reform the restrained feature to within the dimensional tolerance.

In one embodiment, a jig apparatus for bending a malleable tool includes a block having an upper surface and containing, a conical recess extending into the block through the upper surface of the block, defined by an elliptical directrix on the upper surface, an apex within the block, and generatrixes disposed about a central axis of the conical recess extending from the apex to the directrix, and an elongated cylindrical hole, which is sized to fit the malleable tool therein and has a longitudinal axis extending from the conical recess into the block at an oblique angle relative to the central axis of the conical recess, and angular markings disposed on the upper surface and around a circumference of the elliptical directrix.

An apparatus for correcting an aberration in a bullet casing's neck, the apparatus incorporating a support frame; a collet chuck and collet sleeve combination whose collet chuck presents a circumferential array of jaws having longitudinal ends, wherein the collet chuck further has a throat extending longitudinally from the jaws' longitudinal ends; a bullet ogive centering annular land fixedly attached to or formed wholly with the collet chuck, the bullet ogive centering annular land being positioned at an oppositely longitudinal end of the throat; rotatable mounting conical bearings and bushings which attach the collet chuck and collet sleeve combination to the support frame; and a turn wheel connected operatively to the collet chuck and collet sleeve combination.

The present disclosure pertains to a tool and repair method that facilitates restoring an exhaust pipe that has been become deformed as the result of a rear end collision which both restores to the pipes original shape and re-aligns the pipes to their original configuration, so the exhaust pipes can be re-attached to the pipe hanger without the need to replace the exhaust system pipes. The tool is comprised of a hydraulic piston cylinder, a stationary rectangular steel head attached to the body of the hydraulic piston, and a movable flat plate, located inside of the rectangular steel head and connected to the piston shaft of the hydraulic piston cylinder. To use the tool the deformed section of pipe is placed within the head of steel head of the compressive pipe repair apparatus when the cylinder piston shaft and movable flat plate are retracted. The hydraulic piston cylinder is activated by the mechanic and the cylinder piston shaft and movable flat plate will extend upward and contact the bottom of the deformed section is exhaust pipe, exerting compressive stresses against the exhaust pipe until the pipe has been reformed to match the original shape.
