Abstract

De huidige uitvinding heeft betrekking op een werkwijze voor het rollen van schroefdraad op een stang door koude vervorming omvattende volgende sequentiële stappen: het aanbrengen van een stang aan een rolmachine voorzien van drie schroefdraadrollen, het transporteren van de stang doorheen de rolmachine, het wegvoeren van een geproduceerde draadstang, en het testen van de kwaliteit van de geproduceerde draadstang, waarbij montage- en/of instelfouten vermeden worden doordat de schroefdraadrollen een vaste hoek bezitten ten opzichte van de aangevoerde stang. De huidige uitvinding betreft tevens een inrichting voor het aanbrengen van schroefdraad op stangen omvattende een rolmachine omvattende: een metalen basisplaat, een invoer- en uitvoerpijp, drie koppelstukken vastgehecht op de metalen basisplaat, en drie schroefdraadrollen, waarbij de koppelstukken vastgehecht zijn op de basisplaat onder een vaste hoek tussen 3 en 4°, waardoor er bij het vervangen van de schroefdraadrollen na slijtage geen instellingen aangepast moeten worden.The present invention relates to a method of rolling thread on a rod by cold forming, comprising the following sequential steps: applying a rod to a rolling machine provided with three thread rolls, transporting the rod through the rolling machine, carrying away a produced threaded rod, and testing the quality of the produced threaded rod, whereby assembly and/or adjustment errors are avoided because the threaded rollers have a fixed angle with respect to the supplied rod. The present invention also relates to an apparatus for threading rods comprising a rolling machine comprising: a metal base plate, an input and output pipe, three couplers attached to the metal base plate, and three thread rolls, the couplers attached to the base plate under a fixed angle between 3 and 4°, so that no settings need to be adjusted when replacing the threaded rollers after wear.
