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.

On-site pressing of field poles for a hydroelectric generator is provided. A field pole may be placed on a press cart and press bars may be placed on top of the field pole. The press cart is moved along a track to transport the field pole to a pressing unit. Hydraulic cylinders in the pressing unit press the field pole and the press bars between the cart and a top plate of the pressing unit to straighten the field pole.

This invention is an apparatus for straightening a guitar bridge or guitar bridge assembly comprising a U-shaped receptacle with a bottom, a first face and a second face; an adjustable drive on the first face that places force on the bridge; and at least two opposing braces on the second face, and wherein the second face is grooved to create a space between the receptacle and the bridge, and wherein the first and second face contain a sight line and the apparatus contains an adjustable drive which is capable of being turned by a hex wrench so that the force of the adjustable drive on one side and the two opposing braces change the shape of the bridge to a desired shape. The invention is also related to a method for straightening a guitar bridge.

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.
