Publication number: 20130312479Abstract: A bending machine includes a frame, a punch holder provided on the frame, a die holder provided on the frame, a pressing mechanism for pressing a punch toward a die, a first deflection detector for detecting a stroke of the punch, a second deflection detector for detecting an actual displacement of the punch, and a controller; and the controller previously stores a relation between a deflection of the frame and a specification of a sheet material, calculates an actual deflection of the frame by subtracting a detection value of the second deflection detector from a detection value of the first deflection detector, gets a target deflection of the frame based on the relation stored, and controls the pressing mechanism so that the actual deflection becomes consistent with the target deflection. According to the bending machine, working efficiency can be improved by rendering a trial bending unnecessary.Type: ApplicationFiled: February 7, 2012Publication date: November 28, 2013Applicant: AMADA COMPANY, LIMITEDInventor: Hirohito Nagahashi

Publication number: 20130291614Abstract: A lightweight mold for press forming is presented. Molds are characterized in that design forming portions thereof, these design forming portions making contact with a workpiece at the time of press forming and thereby forming a target design on the workpiece, are constructed of rod shaped members (design forming rods). By having the design forming portions be constructed of rod shaped members, the weight of the mold is reduced. It is preferred that the molds are further provided with supporting rods which support the design forming rods, these rod members constituting a framework structure.Type: ApplicationFiled: January 28, 2011Publication date: November 7, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Naoki Ichijo, Yoshiya Sato, Isao Nojiri

Patent number: 8572843Abstract: A method and a manufacturing line allow for the manufacture of piston blanks of dimensions close to the final dimensions, which in the course of subsequent finish-machining need only be machined with removal of material to a small degree. A piston shaft of the piston blank is produced by backward extrusion. At least one hollow throat element is already produced at the piston blank by an upset-forging operation. For this purpose, a special forging tool is provided, which, after the manufacture of the piston shaft, takes effect on the piston blank in such a way that at least one hollow throat element is formed at the latest at subsequent forming of the piston base. In this way, a perceptible reduction is achieved in the weight of a piston in relation to conventionally manufactured forging pistons.Type: GrantFiled: July 18, 2006Date of Patent: November 5, 2013Assignee: ThyssenKrupp Metalurgica Campo Limpo Ltda.Inventors: Carlos Furquim Heraldo, Joao Lester Garcia

Publication number: 20130283882Abstract: The invention relates to a method and an installation for producing a component from sheet magnesium, comprising a forming tool, which comprises a punch and a die, for forming a semi-finished product made of sheet magnesium, in particular a semi-finished product in the form of a sheet magnesium blank, and a device for heating the semi-finished product to an elevated temperature, preferably to a temperature of at least 200° C., prior to the forming. In order to reduce the component costs, the invention proposes that the forming tool is designed without an internal heat source, is provided with a semi-finished product holder on which the heated semi-finished product can be placed in the forming tool without direct contact with the punch and the die, and comprises a drive which brings about a closing speed of the punch and the die in the range of 15 mm/s to 500 mm/s.Type: ApplicationFiled: October 7, 2011Publication date: October 31, 2013Applicants: MGF MAGNESIUM FLACHSTAHL GMBH, THYSSENKRUPP STEEL EUROPE AGInventors: Sascha Sikora, Franz-Josef Lenze, Thorsten Koehler, Ralf Scheitza, Hans-Peter Vogt
