Abstract: A preshaping method for massive forming processes is proposed in which a fixed blank is deformed by at least one roll moving continuously forward along a predetermined contour.

Abstract: A blank is stretch formed into a formed piece by bending the blank over a stationary punch. A draw ring has a step that cooperates with a pad ledge to create a step-ledge. The blank is bent with a reverse bend at the step-ledge. Subsequently, the step-ledge travels a short distance relative to the punch to stretch the blank material. Step-ledge travel is achieved by pre-charged cylinders that travel slightly in response to a force exerted on the draw ring and step-ledge by the press ram after the blank is bent into the reverse bend. The formed piece is cut along a plane through a wall thereof to make a finished piece. The finished piece free edge remains stable and in the same position as when in the press. Consequently, the free edge can be readily aligned with and welded to the free edge of a second finished piece.

Abstract: A method of fabricating an exterior part of a camera is disclosed. The exterior part has an arcuate recess for finger gripping during photography and an arcuately bent portion. The method of fabricating the exterior part includes laminating a plastic protective layer to a surface of a substantially flat stainless steel sheet. An arcuate recess is then formed in the laminated sheet to create a finger grip area. Next, a peripheral flange is formed along a part of the periphery of the sheet, leaving an end portion of the sheet unflanged. The unflanged end portion is manually bent to form an arcuately curved portion with a preliminary curvature. A press die is used to impart a sharper curvature to the curved surface and to perform flanging on the unflanged end portion so as to extend the existing flange along the periphery of the sheet. The extended flange is then ironed to remove any wrinkle.

Abstract: A method and device for manufacturing UOE steel pipes, wherein, when an opening width of the U-can obtained by U-ing press is larger than the die-diameter in an O-press of later step, while said opening is narrowed from the front end by the closing rolls disposed before said O-press and/or at least at the entrance portion of the O-press to be smaller than the die-diameter of said O-press, the U-can is simultaneously conveyed into the O-press, and then, after charging into the O-press, undergoes O-ing press to yield an O-can. The device is preferably configured to have the closing rolls disposed in a roll stand and consisted of multiple pairs, to have a mechanism to prevent the U-can from moving upward during narrowing the opening width, and to have the function of conveying the U-can. Thus, UOE steel pipes for high-strength application corresponding to X80 grade can be efficiently manufactured.

Abstract: The tension and anti-recoil mechanism of the present invention is connected to a tool handle of a cable tie tool. The tool handle has a barrel and a grip depending therefrom. The tension and anti-recoil mechanism includes a regulator grip supported in the barrel. A one-piece cutter actuator is supported in the regulator grip for longitudinal displacement relative to the barrel. A tension limiting mechanism directs a retaining force against the cutter actuator to resist longitudinal displacement thereof relative to the barrel. The retaining force may be controlled to limit the tension produced in a cable tie prior to severing the strap thereof. Recoil of the cable tie tool which may result from the severing is substantially limited by the tension and anti-recoil mechanism.

A longitudinal axial force is applied to the tube in a direction toward the stop member as the expandable head expands the diameter of the tube.

Abstract: The invention concerns methods and devices for bending a cylindrical tube or the like (1) so as to obtain two consecutive sections (2, 3) of said tube forming between them a non-null angle alpha. The method is essentially characterised in that it consists in producing, in the wall (4) of the tube (1), a wave (20) defined between two flanks (22, 23) forming between them a non-null angle beta substantially centred on the separation plane (21) between the two sections, then in producing a permanent plastic deformation of the wave (20) until the value of the angle between the two sections (2, 3) is obtained. The device enables to implement said method. The invention is useful in particular but not exclusively, for producing pipes for transporting fluids in motor vehicles or the like.

Abstract: The cable tie tool has a modular tool head and a tool handle from which the tool head may be detached. The attachment and detachment provided by the modular tool head provides for the use of multiple tool heads with a single tool handle in which is mounted a trigger mechanism. Each modular tool head is secured to the tool handle by a latch mechanism. Each tool head further includes a tensioning mechanism for applying a tension force to a cable tie. Each tensioning mechanism provides for application of a corresponding tension force to the cable tie proportional to the force applied to the tensioning mechanism by the trigger mechanism. The respective tension forces are different for at least one uniform force applied by the trigger mechanism to the corresponding tensioning mechanisms.

Abstract: The cycle counter is incorporated in a cable tie tool and provides an accurate count of the number of cable ties cut by the tool. The cycle counter includes a sensor which detects the displacement of the blade of the cable tie tool required to sever the strap of the cable tie. Alternatively, the sensor detects the condition of a component of the cable tie tool which indicates that the tool has cut the strap of a cable tie. The sensor generates a cut signal indicating that the strap of a cable tie has been cut. The cycle counter further includes summing devices for processing the cut signals and generating additional signals for transmission to a display device. The display device communicates to an operator the total number of cable ties severed by the cable tie tool. The display device also communicates to the operator the total number of selected cable ties severed by the cable tie tool.
