摘要： A twisting machine for polygonal cross-section bars having an independent jaw chuck fitted on a mandrel and a counteracting support slidable on a prismatic guide, which is firmly connected to the machine and parallel to the mandrel; the jaw chuck includes a mutually co-operating rotary connection between the mandrel and the chuck in the form of a groove for ball-recirculating and a mutually engagement, such as an abutment projection diametrally projecting from and integral with the mandrel and a longitudinal pin connected to the chuck, which are adapted to drive into rotation the chuck by the mandrel, after a free rotation of the mandrel along an arc with an angle less than a round angle.

摘要： The present invention relates to a forming press of crankshafts which is safe, has a slide of large strength and high forming precision, and is capable of high-speed cyclic operation. A forming press of crankshafts includes a forging unit for twisting and a forging unit for reshaping, wherein (i) a twisting oil-hydraulic cylinder is mounted on the crown, (ii) twisting push rods are disposed along outer surfaces of the slide, and (iii) the bottom ends of the twisting push rods are connected by twisting-down beams and untwisting beams. The slide is of inverted T-form in section, and the pressing block is of H-form as seen from above and of inverted U-form as seen from one side. Therefore, they do not interfere with each other and a large stroke can be secured. The twisting angle is set using an upper stopper provided in the pressing block and an automatic telescopic lower stopper provided in the slide and freely movable toward and away from the upper stopper. An upper guide and a lower guide are provided between the pressing block and the slide. Each guide directs four portions, around the lower stopper, of the pressing block against its forward, backward, rightward, and leftward deviation.

摘要： In an exemplary embodiment of the invention, a machine for shaping a bus bar comprises a first retaining device, a second retaining device, a twisting device and an offset mechanism. The first retaining device is arranged to secure a first section of the bus bar in a first plane. The second retaining device is arranged to secure a second section of the bus bar. The twisting device is connected to the second retaining device and rotates the second retaining device to twist the second section of the bus bar about a longitudinal axis of the bus bar positioning the bus bar in a second plane. The offset mechanism is connected to the first retaining device and is arranged to offset the second section of the bus bar in a third plane, the third plane generally parallel to the second plane.

摘要： In a method for forming a three-dimensional object and in particular to a method for forming a three-dimensional beam, it is desirable to form three-dimensional beams (5) having complex forms by using an efficient forming process for the beams which may be incorporated into existing high volume production techniques. The apparatus (1, 31) for forming three-dimensional beams (5) comprises a support device and an actuation device. Support members (2, 32, 41, 51, 61) spaced about the longitudinal axis of the support device locally define an opening (4, 35, 43, 53, 63) for supporting a section of the beam (5). The position of adjacent openings (4, 35, 43, 53, 63) relative to one another defines the overall form of the beam (5) and the actuation device defines the position of each opening (4, 35, 43, 53, 63).
