A press-molding system 1 includes a press-molding unit 2 having a main body 21, a lower molding die 23 installed at the lower portion of the main body 21, a drive part 24 installed to the main body 21, and an upper molding die 26 installed so as to be vertically movable with respect to the lower molding die 23 by the drive part 24, a workpiece weight measuring unit 5 that measures the weight of a workpiece, and a controller 7 that controls the drive part 24 according to the weight of a workpiece measured by the workpiece weight measuring unit 5.

A holding device of a forming machine includes a base, a rotating set, a clamping set, and a transmission set. The rotating set penetrates through the base. The clamping set is disposed under the base. The transmission set drives a rotation of the rotating set. Further, the clamping set has a link axle and a link unit driven by the link axle in order to render two clamping units able to catch or release blanks. Simultaneously, the transmission set has a driving unit and a transmission unit adapted to drive a rotation of the driving unit whereby the link axle, the rotating base and the clamping unit are concurrently rotatably turned in a clockwise or counterclockwise direction by 180 degrees. Thus, the holding device can clamp blanks at any place between dies of the forming machine according to the need to obtain a quick processing operation.

A progressive forming machine having a frame supporting a plurality of workstations uniformly spaced in a horizontal plane, a transfer mechanism for shifting parts from one station to another and from a last station to a discharge station, a conveyor in the frame for lowering parts from the transfer discharge station, the conveyor having individual part carriers, the conveyor being arranged to present a carrier beneath the discharge station in timed relation to the operating cycle of the machine.

A method and a plant for manufacturing fasteners, in particular screws, along an automated production line; the method comprising the following steps: feeding the raw material made of titanium; heating the raw material to a predefined temperature; cutting one or more pieces of a predefined length, in succession, from the heated raw material; deforming plastically each piece by means of one or more finishing stations, so as to obtain a fastener; heating, during the deforming step, the material that passes through each workstation to a predefined temperature; wherein the material manipulated along the production line during the feeding, heating, and deforming steps is automatically transported along the production line.

A stretch-rolling device and a stretch-rolling method for pressure-forming workpieces by rolls. The stretch-rolling device includes a pair of work-rolls with two rolls, which can each be rotated about their roll axes and form a roll gap between them. The rolls implement a plurality of stages in an axial direction, which are set up for stepwise deformation of the workpieces as the workpieces pass through the stages successively. A manipulator with a plurality of gripping devices, which are arranged on a working side of the pair of work-rolls, are set up to grip the workpieces at an assigned stage to guide the workpieces through the roll gap in a feed/retraction direction. A support is arranged to temporarily support the workpieces in cooperation with the manipulator to transfer the workpieces to another gripping device, which is preferably an adjacent gripping device of the next higher stage.
