Abstract: Apparatus for roll grooving thin wall pipe comprises a housing supporting a drive roll and an arm pivotally mounted on the housing and supporting a grooving roll. A feed screw between the housing and arm provides for pivoting the arm to displace the grooving roll radially toward and away from the drive roll, and a release arrangement between the feed screw and arm is operable to release the arm from the screw to protect the screw from damage. The feed screw is mounted on the housing and arm by a double pivot arrangement. Self-tracking during a roll grooving operation is provided by dimensionally different knurling on axially opposite sides of the rolling groove of the drive roll and/or by inclining the axis of the grooving roll relative to the axis of the drive roll and/or by tapering the rolling surface on the rolling projection of the grooving roll and/or by supporting the axially outer end of the drive roll against deflection.

Abstract: The present invention relates to a method and an apparatus for producing rotationally symmetric components by means of rolling. For producing a rotationally symmetric component having a profile without any bevels from a blank, the present invention suggests that an annular blank should be deformed into a profiled annular component in a first step by means of rolling between a first inner roll and a first outer roll in a diameter-enlarging mode until the radial growth is limited due to the fact that the profiled annular component comes into contact with at least one additional outer roll. In a second step, the profiled annular component is deformed in a profiling mode between a second inner roll and at least one of said outer rolls on its inner and/or outer circumferential surface(s).

Abstract: Beading of containers such as two and three piece can bodies by rolling the can body between tools, typically a roll/roll or a roll/rail of a rotary turret (10) system. During beading, a load is applied along the central axis of the can body, whereby axial and panel performance of the beaded can is improved. This load is applied for example by the use of miniature air bags (19) which are fixed to the turret.

Abstract: The present invention relates to a reinforcement device (1, 100), especially a reinforcement device useable in a machine for laminating rims for wheels of automotive vehicles, the machine comprising at least two substantially parallel laminating axles (21, 22, 121, 122), the reinforcement device (1, 100) being characterized by comprising a body (4, 101) associated to the housing (2, 102) of the lamination machine, the positioning of the body being variable with respect to the housing (2, 102), the body (4, 104) being provided with two bearings (41, 42, 141, 142) supportable on respective end regions of the axles (21, 22, 121, 122), so that the axles (21, 22, 121, 122) are maintained substantially parallel during the operation of laminating the rim, at least one bearing being moveable with respect to the reinforcement device by a moving means (51, 52, 150). With great advantages, the invention can be used in usual lamination machines existing in the factory, thus making it possible to manufacture larger and more resistant wheel rims, with good quality and reduced cost, without potentially destructive overloads on the machine. In addition, the device brings about greater uniformity between the successive lots of rims produced, besides reducing the dimensional tolerances of each piece, which results better quality and more satisfaction of the clients.

Abstract: A cold rolling apparatus includes a forming roll which applies a forming load to a tube when cold rolling the tube, and a hydraulic positioning assembly including a positioning roller disposable for initial contact with a tube surface and arranged to apply a positioning load to the tube. A hydraulic circuit is coupled to the forming roll and to the hydraulic positioning assembly such that the positioning load is related to the forming load. A face plate mounted for movement with the forming roll, and the positioning roller is mounted to the face plate. The face plate is coupled to a piston of the hydraulic positioning assembly for movement with the piston relative to the forming roll. The piston is housed within a cylinder body coupled to a guide block which is coupled to the forming roll. The forming roll is an outside roll, and the cold rolling apparatus includes two positioning rollers.
