Patent number: 6609042Abstract: An automatic production and assembly machine focuses on the fact that each unit is provided with coding indicating at least the type of the specific function unit. The coding is transmitted via data transmission existing between the individual function unit and a central control unit. The coding makes possible continuous checking of the control program, such that certain program sequences for certain workstations are only executed when the coding of these workstations agrees with the respective program sequence. A number of other important functions are monitored, corrected and made to coincide with the central programming.Type: GrantFiled: June 22, 1999Date of Patent: August 19, 2003Assignee: Feintool International HoldingInventor: Siegmund Kumeth

Patent number: 6553656Abstract: An automatic assembly or production machine and workstation for such a machine which has a rotor that is rotatable around a vertical machine access, and has several receptacles on the periphery of the rotor for components or work pieces to be assembled or for subassemblies. The machine has a central drive means for the rotor for moving the receptacles in a cyclic movement from one work position to the next. Each work position has primary functional elements with a common control unit for them driven by a central drive assembly and producing controlled movements of the element in at least one axial direction in synchronization with the cyclic rotary movement of the rotor.Type: GrantFiled: March 10, 2000Date of Patent: April 29, 2003Assignee: Feintool International HoldingInventor: Siegmund Kumeth

Patent number: 6442829Abstract: A production and/or assembly apparatus for processing workpieces has a stationary frame forming basic unit of the system. A motion device is movably supported on the frame. A plurality of workpiece carriers are moved in an indexed manner relative to processing modules and feeders arranged in a fixed position on the frame. The workpiece carriers and/or the processing modules and/or the feeders are detachably fastenable in their respective positions by fastening devices which have an identical design in each case for the workpiece carriers and/or the processing modules and/or the feeders. The apparatus can be reset or retooled by simply exchanging one or more of the workpiece carriers, one or more of the processing modules, and/or one or more of the feeders. The resetting and retooling thereby does not affect the frame forming the basic unit.Type: GrantFiled: February 22, 1999Date of Patent: September 3, 2002Assignee: Feintool International HoldingInventor: Sigmund Kumeth

Patent number: 6240818Abstract: The press slide of a hydraulically or mechanically driven precision blanking press is non-positively connected with a crosshead by means of columns. The knife-edged ring cylinder is integrated in the crosshead and the supporting force of the knife-edged ring cylinder is taken up by the slide. During a cutting stroke, there is no relative movement between the knife-edged ring cylinder with piston and the slide. The counter cylinder is located in the lower crosshead of the stand. During a cutting stroke, there is no relative movement between the counter cylinder and the workpiece in the tool. The working force of the main drive is not reduced by the pressing force of the knife-edged ring and counter cylinder.Type: GrantFiled: September 25, 1998Date of Patent: June 5, 2001Assignee: Feintool International Holding AGInventor: Horst Baltschun

Patent number: 6182360Abstract: A method of producing and stacking components from individual layers which are punched, cut or the like out of a hardened material strip. According to the method, layers are removed from a hardened material strip, the removed layers are pressed back into the material strip and pressed out of the latter in a subsequent station (ii). They are then inserted into a stack magazine in which the individual layers are centered and assembled to form a component, the component then being removed from the stack magazine.Type: GrantFiled: February 18, 1999Date of Patent: February 6, 2001Assignee: Feintool International Holding AGInventor: Johannes Haack

Patent number: 6125527Abstract: In a process for producing precise cut surfaces on a workpiece by stamping or blanking, in particular by fine-edge blanking, a contour first is stamped or blanked out at a distance (a) from the actual contour of the workpiece, and the workpiece then is scraped down to its final contour. It is intended here, in a first step, for only up to part of the thickness (d) of the workpiece to be scraped and, in a following step, for the contour of the workpiece to be achieved by scraping in the opposite direction to the first step.Type: GrantFiled: December 9, 1997Date of Patent: October 3, 2000Assignee: Feintool International HoldingInventors: Junichi Sunaga, Wolfgang Rose

Patent number: 6058758Abstract: The invention concerns a press, in particular, a precision blanking press, with a slide (1) and a press lower part (3) associated with the slide, a tool (17) being located between the slide (1) and the press lower part (3). According to the invention, a hydraulic plate (9, 10) is disposed between an upper tool and the slide (1) and/or a lower tool and the press lower part (3).Type: GrantFiled: September 23, 1998Date of Patent: May 9, 2000Assignee: Feintool International HoldingInventor: Hans Wymann

Patent number: 5247862Abstract: The present invention relates to a process and a device for producing burr-free workpieces by blanking using a counterblanking tool. The counterblanking tool has an upper tool and a lower tool which include respectively an upper blanking die and a lower blanking die and an upper punch and a lower punch. The counterblanking tool further includes a ram plate which moves one of the upper and lower tools towards the other of the upper and lower tools. The ram plate moves in a continuous ram stroke during which a blanking strip from which a workpiece is to be blanked is clamped between the upper and the lower tool. During the initial portion of the blanking operation, the blanking dies remain in place while a first one of the punches, travels further and a second one of the punches travels back until a limit stop is reached. During this travel the first punch cuts partly into the blanking strip.Type: GrantFiled: September 19, 1990Date of Patent: September 28, 1993Assignee: Feintool International HoldingInventor: Johannes Haack

Patent number: 5016807Abstract: In a method for producing workpieces of metal having profiled outer and/or inner contours which have any desired shape contours and are or can be profiled in thickness, the workpiece (R) is to be divided in terms of construction into simple part-profiles (4, 7, 13, 14), which are then produced by precision blanking and then fitted together and joined to one another by lamination to form the finished part.Type: GrantFiled: November 27, 1989Date of Patent: May 21, 1991Assignee: Feintool International HoldingInventor: Johannes Haack

Patent number: 5007264Abstract: In a method for the bending of workpieces by swivel bending jaws, the bent-off part is to assume a predetermined bending angle with respect to the workpiece, for this purpose, in a first bending operation, at least one corresponding leg is to be bent off from the workpiece by means of the swivel bending jaws. Then, the swivel bending jaws are released from the leg and a springback of the leg or the actual bending angle is determined by direct measurements and compared with a set bending angle. Subsequently, an agreement is established between set bending angle and actual bending angle by a renewed bending operation, by a bending-over.Type: GrantFiled: November 9, 1988Date of Patent: April 16, 1991Assignee: Feintool International HoldingInventor: Johannes Haack

Patent number: 4718339Abstract: Two locking clamp-bars are slidingly accommodated in two parallel T-slots of an upper plate and in T-slots of upper grippers of a press. Each locking clamp-bar has two T-pieces. Upon rising of a lower plate, acting as the press ram, together with the set of tools, the T-pieces of locking clamp-bars are in a first position, in which they can enter recesses in further T-slots in an upper part of the set of tools or in an upper auxiliary plate. By means of a drive device, the T-pieces are pushed into a second position, in which they snap into the further T-slots. In this press, a non-destructive removal of tools is ensured in the event of a defective chucking mechanism.Type: GrantFiled: April 30, 1986Date of Patent: January 12, 1988Assignee: Feintool International HoldingInventor: Hans Wymann
