Abstract: A combination punch press and laser machine has its punch press system and worktable mounted to one frame while its laser system mounted to another frame. The two frames are not in contact with each other, but are positioned such that a cantilever member of the frame whereon the laser system is mounted extends over the worktable so that the laser cutting head which is mounted to the end of the cantilever member superposes over a particular location of the worktable whereat the cutting of the worksheet by the laser beam is to be effected. This particular laser cutting location is positioned relative to the location of the worktable whereat the punching of the worksheet is to be effected by the pair of coacting upper tool and lower die of the punch press system.

Abstract: A laser cutting system has a specially designed frame that allows the laser cutting head to be mounted to the underside of a cross beam for a more efficient movement. The frame is further designed so as to allow the accessing of the work area of the laser cutting system along three different directions. The movement of the laser cutting head for fabricating a sheet placed in the work area of the laser cutting system is effected by a process that takes into consideration a number of parameters and determined data all of which are interpolated for generating optimal movements to further enhance the operating efficiency of the laser cutting system. The laser resonator of the laser cutting system of the instant invention is configured to have a telescopic system that maintains the density and power of the laser beam by auto focusing the same so that optimum cuts can be effected irrespective of whichever area of the worksheet is to be fabricated.

Abstract: The working machine comprises a first (ET) and a second (TT) machining means, at least the first one (ET) being arranged to move in relation to the machine body (28) towards the second one (TT), to accomplish machining of a sheet material, wherein the sheet material to be worked is placed between the machining means (ET) and (TT). At least one of the machining means (ET and TT) is provided with means (7, 9) for conducting the transfer and working movements of said tool (ET, TT). The first part (7) of the means is fixed to the machining means (ET, TT), and the second part (9) of the means is fixed to the machine body (28), to be movable in relation thereto by actuators (10, 11, 14-26, 39, 41) in the machine body (28). The movement of the second part (9) of the means (7, 9) in relation to the machine body (28) during machining based on pressing of the sheet material is transmitted from the second part (9) to the first part (7) by a contact surface connection.

Abstract: The invention relates to a sheet fabrication machine that machines worksheets. The body of the machine includes first and second machining tool mechanisms at least one of which being arranged to move in relation to the machine body towards the other to machine a worksheet placed between the machining tools. At least one of the machining tool mechanisms is provided with a contact mechanism that conducts the transfer and working movements of the tool. One part of the contact mechanism is configured to have at least one guide surface part formed as a beveled surface in relation to the direction of movement of the machining tool. A contact surface connection between a first part and a second part of the contact mechanism in relation to the guide surface part defines the position of the machining tool.

Abstract: The invention relates to a sheet metal work center and a method for fabricating sheet metal therefrom. In the sheet metal work center, a locking arrangement is placed between the upper tool and a releaser, and the transfer device is arranged to consist of two parts. The sheet metal work center is adaptable to work in either a passive or active mode. In the passive mode, the releaser is positioned at a certain distance from the surface of the sheet, and the movements of the upper tool and the releaser are made with the locking arrangement locked and either part of the transfer device used. In the active mode, the releaser is positioned to be in contact with the sheet, and the movements of the upper tool and releaser are made with the locking arrangement locked and either part of the transfer device used.

Abstract: The invention relates to a sheet metal work center, in which a locking arrangement (15) is placed between the stationary part (9) of the buffer structure (2) and the releaser (13), wherein at least some of the vertical movements of the upper tool (7) and the releaser (13) can be implemented by using the transfer device (12), the stationary part (9) of the buffer structure (2) and the releaser (13) being connected with the locking arrangement (15).
