摘要： A linear accelerator system for linearly advancing an electrically conductive, elongate workpiece, such as tubing, along its longitudinal axis toward a cutoff station or the like includes a helically configured electrical coils concentrically disposed around the workpiece for inducing an electromagnetic field which imposes an axial force on the workpiece. An adjustable stop assembly engages one end of the workpiece to allow selection on the length to be cut. A switch operated by the stop assembly produces a first control signal for controlling a relay which deenergizes the coil; the relay reenergizes the coil in response to a second control signal produced by another switch which senses the completion of the cutoff operation. Sleeves removably mounted on the coil to accommodate workpieces having various diameters. In lieu of the stop assembly, a length encoder may be optionally employed in combination with the accelerator or a separate retarding device to control feed length.

摘要： The present invention concerns a line (1) for producing metal profiles (P1, P2, P3) for plasterboard false ceilings, comprising in sequence along a profile advancement direction (X) : a profiling machine (10); a cutting group (20); a punching group (30); a system (40) for extracting the finished metal profiles (P1, P2, P3) from the punching group (30); a management and control unit (50). The punching group (30) comprises: - a first punching press (310) of the portal type having an elongated punching head (311) along a first operating direction (Y1); and a plurality of second punching presses with a C-support (320a, 320b, 320c), which are arranged downstream of said first punching press (310) and which are aligned with each other to form a row along a second operating direction (Y2) parallel to the first (Y1). The management and control unit (50) is configured so as to alternatively operate in use said first punching press (310) and at least one part of said second punching presses (320a, 320b, 320c) as a function of the type or length of the metal profiles (P1, P2) in output from the cutting group (20). The system (40) for extracting finished metal profiles (P1, P2, P3) from the punching group (30) is integrated with said second punching presses (320a,b,c) and comprises a conveyor belt (41).

摘要： A disclosed forming system is a forming system which expands and forms a metal pipe in a die. The forming system includes a preliminary forming apparatus which preliminarily forms a metal pipe material, a forming apparatus which includes a gas supply unit which supplies gas into the preliminary-formed and heated metal pipe material to expand the metal pipe material and a main body portion to which the die is attached, and a cutting device which cuts at least a portion of the formed metal pipe. The gas supply unit is provided so as not to be disposed on a first straight line which connects the preliminary forming apparatus and the main body portion in a plan view and a second straight line which connects the cutting device and the main body portion in a plan view.

摘要： Described herein are a method and a device for automatically loading a predetermined number of metal bars (4) from a collection workstation (5), in which the bars (4) are arranged in a bundle (3), to a reception workstation (13). A magnetic-effect lifting device (8) can be displaced between a lowered position for picking up the bars (4) and a raised position. A restricted passage (14) is provided that is to be traversed by the bars (4) that are lifted, such as to enable the lifting device (8) to bring just one bar (4) or portion of bar (4) at a time up to the raised position (13). Each time a bar (4) reaches said raised position, it is pushed laterally by a pusher member (15) and deposited on a support (18). When a predetermined number of bars has been unloaded onto the support (18), a gripper-type transferring device (24) grips said bars and brings them into a final position (7).

摘要： A workpiece (1) for a hollow rack shaft is a substantially rectangular plate. The opposite two sides of this workpiece are respectively provided with a complementary profile composed of the continuation of a convex portion and a concave portion and when the workpiece is cylindrically formed, the profiles are mutually engaged. As the width (w1) of a part the width of which is the largest in the convex portion is larger than that of a part the width (w2) of which is the smallest in the concave portion, the two sides are prevented from being detached after engagement. Further, the opposite convex portion and concave portion are mutually caulked and hereby, mutual gap is removed.

摘要： Bending machine (10) to obtain shaped elements from pre-cut profiles (11), equipped with a drawing assembly (14) which draws the profiles (11), first shearing means (13) arranged downstream of the drawing assembly (14) and bending means (12) arranged downstream of the first shearing means (13). Downstream of the bending means (12) are arranged second shearing means (15) to eliminate the terminal segments of the profiles (11) corresponding to the difference between the linear development of the shaped element to be produced and the length of the pre-cut profiles (11).
