Die block, steel-rule die assembly comprising the same, and method thereof

12) A cutting die assembly for cutting and/or punching a material sheet using a press, and comprising:

• at least one steel-rule defining a knife configured for cutting and/or punching the material;
• a die block configured to be inserted into the press and comprising at least one kerf perpendicularly extending from an upper surface to a bottom surface of the die block, each kerf being configured to receive the at least one steel-rules, the at least one steel-rules being partially inserted into the corresponding at least one kerf for outwardly exposing the knife of each steel-rule;
• and
• at least one element having magnetic properties and being located into the die block in proximity to each kerf for providing a magnetic field that retains the at least one steel-rule when the at least one steel-rule is received into the corresponding at least one kerf.

24) A method for manufacturing a stabilized die block intended to be used in collaboration with a press for cutting and/or punching a sheet of material, the method comprising:

• providing a die block with at least one kerf;
• and for each kerf:
• positioning at least one element having magnetic properties in proximity to the kerf for providing a magnetic field;
• and
• partially inserting at least one steel-rule into the kerf for retaining the at least one steel-rule into the kerf while exposing a knife of the steel-rule outwardly projecting from the die block;
• the magnetic field stabilising and aligning each steel-rule once inserted into the kerf.
