WELDING WIRE STRAIGHTENER Russian patent published in 2007 - IPC B21F1/02 B21D3/12 B21C19/00 B21C43/04 B24B5/38 

FIELD: plastic metal working.

SUBSTANCE: invention is designed for straightening annealed wire, diameter up to 3 mm. proposed device contains hollow cylinder secured in rotator and provided with axial holes in base to pull wire through. Device for forced moving off wire from axis of rotation of hollow cylinder is arranged in cylinder space. Cylinder space is partially filled with abrasive powder. Device for forced moving off of wire from axis of rotation of hollow cylinder is made in form of weight which can be mounted for movement on wire. Weight can be made in form of bushing with diameter of axial hole exceeding sum of diameter of wire and reduced diameter of wire and reduced diameters of two largest particles of abrasive powder. Cylinder space can be filled with abrasive powder at least by 30% of its volume.

EFFECT: reduced wire pulling force and provision of cleaning of wire from oxide film and surface contaminants.
