Abstract
Drawing and straightening unit (10) having at least one first roller (12) and at least one second roller (16, 17, 18) opposite said first roller (12) with respect to an axis of feed (X) of said at least one metal product (P). The present invention also concerns an apparatus (100), comprising a feed unit (119) and a drawing and straightening unit (10), and a corresponding method to draw and straighten metal products (P) with said drawing and straightening unit (10).
Claims11
An apparatus for working metal products comprising a drawing and straightening unit for feeding metal products, said unit comprising at least one first roller provided peripherally with a plurality of circular grooves configured to accommodate at least one of said metal products, and a number of second rollers opposite said first roller with respect to an axis of feed of said at least one metal product that is equal to the number of grooves of the first roller, so that each second roller is aligned with a respective groove, wherein there is an adjuster associated with said drawing and straightening unit and configured to move said unit in a direction of adjustment transverse with respect to said axis of feed so as to align, in use, one or more of said grooves with respective metal products fed by a feed unit disposed upstream.
A drawing and straightening method for feeding one or more elongated metal products to a machine for working such metal products, comprising:
- a step of supplying one or more metal products to a drawing and straightening unit carried out by a feed unit which supports them slidingly,
- a step of drawing said one or more metal products by using said drawing and straightening unit in which at least one first roller accommodates, in respective grooves, said one or more metal products which are simultaneously contrasted in position by a number of second rollers with respect to an axis of feed equal to the number of grooves of the first roller, so that each second roller is aligned with a respective groove,
- wherein between said supply step and said drawing step there is provided an adjustment step in which said drawing and straightening unit is moved in a direction of adjustment transverse with respect to said axis of feed so as to align one or more of said grooves with respective metal products, and in that said drawing step is performed with the number of second rollers.
