Definitions
- the invention aims at a solution of these problems by means of a resilient snap device which presses the dies against the base plate.
- the invention will be more specifically described in the following specification with drawing figures showing:
- FIG. 1 cross section of a fastening device according to the invention.
- FIG. 2 a section on line 2-2 in FIG. 1.
- FIG. 3 a section on line 3-3 in FIG. 1.
- FIG. 4 the same fastening device seen from the cutting edge side of the knife.
- the cutting die is attached to the base plate 11 by means of a yoke consisting of a spring 12 and two hooks l3 riveted thereto.
- the spring bears against a tie member 14'on the die 10 and the hooks enter into holes 15 in the base plate, said holes having wider portions 16 at the bottom side of the plate for catching engagement of the hooks.
- the wider portion 16 is so deep that there is room for the head of the hook in it.
- the yoke forms a unit that is separate from the die, and thus the die is free to move somewhat laterally in all directions and also to be somewhat turned around an axis perpendicular to the base plate at the same time asit is held in contact with the base plate by the pressure of the 2 spring 12.
- the hooks comprise an upper portion 17 having a greater diameter than the holes 15 and a lower portion 18 having a smaller diameter than the holes 15.
- the portion 18 has at its lower end a laterally extending projection 19 which engages the wider portion 16. As is indicated in FIG. 1, these projections 19, 19 preferably extend in opposite directions with regard to each other, for ready dislodgement.
- the holes 15 are arranged in a pattern forming the comers of a regular hexagon so that the yoke can be placed in any pair of diametrically opposed holes in the hexagon. This makes it possible to orientate the die in an arbitrary direction around an axis perpendicular to the plate. Of course other patterns of holes can be used for the same purpose.
- the described fastening device renders the die yieldable in the lateral direction, so that adjacent knives adjust themselves automatically in relation to one another and the lateral forces between them are eliminated.
- the device is also easy to attach and to detach.
- Means for fastening cutting dies on a base plate comprising a resilient yoke with one hook at each end, said hooks engaging recesses in the plate, the intermediate portion of the yoke acting on the die, urging it resiliently against the plate.
