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.

Disclosed in the present disclosure is a wheel locating surface correction device, comprising a frame, a correction ring and a correction plate. The correction plate is provided above a wheel blank. The structure can correct the roundness of the radial positioning surface of the blank, and the flatness of the axial positioning surface of the blank before machining to improve the roundness of the blank rim, improving the wheel yield and the processing quality.

A robot for straightening double thin-wall section pipe with multi-cavity special-shaped, includes two racks, a positioning component, a shaping component and a driving component. The double thin-wall section pipe is located in the positioning component, and the shaping component is used for shaping the pipe by the driving of the driving component. The robot improves the working efficiency, and is not only compact in structure design, stable in movement, precise in positioning and reliable in locking, but also convenient for disassembly and maintenance.
