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).
Claims14
A method of operating a sheet metal work center having a body, a work table whereon a sheet to be worked is placed, upper and lower tools in punch and stopper structures, respectively, for effecting work on said sheet on its opposite sides, a releaser in operative connection with said upper tool, and a transfer device for moving said upper tool and said releaser in the vertical direction, comprising the steps of:
- a) placing a locking arrangement between a stationary part of said punch structure and said releaser;
- and
- b) utilizing said transfer device to drive said upper tool and said releaser to move relative to said lower tool (1) in a passive mode with said locking arrangement locked wherein said releaser is at a given distance from the surface of said sheet, or (2) in an active mode with said locking arrangement opened wherein said releaser is in contact with the surface of said sheet.
Sheet metal work center comprising:
- a body;
- a work table whereon a sheet to be worked is placed;
- upper and lower tools in punch and stopper structures, respectively, for effecting work on said sheet on its opposite sides;
- a releaser working in cooperation with said upper tool;
- a transfer device for moving said upper tool and said releaser in the vertical direction;
- and
- a locking arrangement placed between a stationary part of said punch structure and said releaser, wherein said upper tool and said releaser are adaptable to be driven by said transfer device to move along said vertical direction, said stationary part of said punch structure and said releaser being connected with said locking arrangement.
Sheet metal work center comprising:
- a body;
- a work table whereon a sheet to be worked is placed;
- upper and lower tools in punch and stopper structures, respectively, for effecting work on said sheet on its opposite sides;
- a releaser working in cooperation with said upper tool;
- a transfer device for moving said upper tool and said releaser in the vertical direction;
- and
- a locking arrangement working cooperatively with said releaser, and adaptable to lock said releaser in a position fixedly spaced from the top surface of said sheet as said upper tool is driven by said transfer device to effect work on said sheet.
A method of effecting work in a sheet metal work center having a body, a work table whereon a sheet to be worked is placed, upper and lower tools in punch and stopper structures, respectively, for effecting work on said sheet on its opposite sides, a releaser working in cooperation with said upper tool, and a transfer device for moving said upper tool and said releaser in the vertical direction, comprising the steps of:
- a) effecting a locking arrangement to work cooperatively with said releaser;
- and
- b) actuating said locking arrangement to (1) lock said releaser in a position fixedly spaced from the top surface of said sheet as said upper tool is driven by said transfer device to effect work on said sheet, or (2) not lock said releaser while said upper tool is driven by said transfer device so that as said upper tool is effecting work on said sheet, said releaser is in contact with the top surface of said sheet.
