摘要： A flange forming drill means for drilling a hole through the side of a pipe or the like and for forming a hole encircling flange. The drill means comprises: a body (1), a drive shaft (2) rotatably journalled to the body, a drill rod with its drill bit (5) mounted on the end of the drive shaft (2), forming members (6) partly fitted within the drill rod (5), an adjustment member (7), by turning of which around the drill rod the forming members (6) can be made to project beyond the jacket surface of the drill rod (5), supporting legs (8) by which the device can be supported against a work piece (10) and which are fitted on the body (1) on either side of the drive shaft (2) in parallel relationship therewith, a feeding nut (13) mounted on the supporting legs (8) and which can be opened and closed for removal from and engagement with a feeding screw (14) formed on the drive shaft (2). When the drive shaft (2) is rotating and the feeding nut is in the closed position, the supporting legs (8) project outwards from the body (1) resulting in rising of the projecting forming members (6), rotating along with the drill rod (5), from below the edges of the hole and thus forming a flange. The feeding nut (13) is arranged to close automatically by means of a link mechanism (16-20) when the supporting legs (8) have moved a certain distance into the body (1). To the supporting legs (8) are secured brake bits (11) at such a level that they respond to the adjustment member (7) when the supporting legs (8) have moved said certain distance into the body (1). Thereby said brake bits (11) turn the adjustment member (7) relative to the drill rod (5) and effect the extension of the forming members (6) substantially simultaneously with the closure of the feeding nut (13).

摘要： A flange forming drill means for drilling a hole through the side of a pipe or the like and for forming a hole encircling flange. The drill means is provided with a drill rod (1) mountable on a rotating machine and fitted with a drill bit (4) and associated forming members (3) which, after the hole has been drilled, can be extended down below the edges of the hole by turning an adjustment member (2) fitted around the drill rod. The adjustment member (2) is enclosed in an externally smooth protective shield (7), which is in engagement (8, 9) with the adjustment member (2), so that their relative rotation around the drilling axis is eliminated. To the drill rod (1) is secured a locking means (16) to which the shield (7) and adjustment member (2) can be removably locked in various angular positions around the drilling axis. The locking means comprises a locking flange (16) provided with two holes or recesses (17, 18) defining the terminal positions of locking. In the first terminal locking position the forming means (3) lie completely within the outer face of the drill bit (4) and in the second terminal locking position the forming means (3) extend or project from the drill bit (4) so as to correspond to the desired internal diameter of the flange (11).
