摘要： A device (10) for making efficient Y-pipes has a first piece (200) configured to hold a Y-pipe (100) that has a holder portion (220) and a jaws portion (240), the jaws portion being moveable between a first configuration and a second configuration, and a second piece (250) configured to be inserted into the vertex (120) of the Y-pipe that has a wedge portion (260) and a punch portion (270), the wedge portion being configured to be inserted into the vertex of the Y-pipe and the punch portion having a tip (280) and fitting at least partially within the wedge portion and being moveable with relation to the wedge portion between a retracted position and an extended position. The device also has a control system (300) configured to control the movement of the jaws portion and the punch portion such that the Y-pipe held between the first piece and second piece has its vertex angle decreased.

摘要： The present disclosure discloses a terminal bending unit including: a frame and a bending tool pivotally mounted on the frame. A row of receiving slots is formed in a bottom surface of the bending tool, and terminals to be bent are adapted to be received and positioned in the corresponding receiving slots. The terminals received in the corresponding receiving slots are bent under press of the bending tool when the bending tool is rotated. It is only necessary to turn the bending tool to achieve bending of the terminals, thereby improving the bending efficiency of the terminals. In addition, a row of terminals may be bent simultaneously by the bending tool, which further improves terminal bending efficiency.

摘要： The invention pertains to the field of steel processing and steel production, in particular of the production of steel profiled elements. The invention relates to a method for producing a steel profiled element, comprising the following steps: providing a workpiece (2, 44, 52), in particular a steel blank, preferably a steel strip blank; forming a weakened point (10) in the region of a planned bend of the workpiece (2, 44, 52); and bending the workpiece (2, 44, 52) to produce a bend in the workpiece (2, 44, 52). After the bending, the weakened point (10) is strengthened by welding.

摘要： Disclosed is a cutting blade bending apparatus. The apparatus comprises a nozzle section for feeding a cutting blade into a bending area through a guide opening which is defined therein in a lengthwise direction of the cutting blade; a first bending member for bending the cutting blade fed into the bending area, in one direction; a second bending member for bending the cutting blade fed into the bending area, in the other direction; a first rotating body for firmly supporting the first bending member and guiding rotation of the second bending member; a second rotating body for firmly supporting the second bending member and guiding rotation of the first bending member, the second rotating body being rotated independent of the first rotating body; and a driving section for rotatably driving, at a time, one of the first and second rotating bodies.

摘要： The invention relates to a method for producing bent spring rails from an endless spring band. The method is characterised by the following steps: continuous bending of a section of spring band; cutting the bent section of spring band into a spring rail; discontinuous reverse bending to reduce the internal stresses of the bent, cut-to-length spring rail by subjecting the spring rail to at least one reverse bending force; and/or heat-treating the cut-to-length spring rails, the heat treatment being a low-temperature treatment in this case, preferably at a temperature of less than 200 °C.
