Die block, steel-rule die assembly comprising the same, and method thereof
11833705 · 2023-12-05 · ·

The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

PRESS WORKING METHOD AND PRESS WORKING APPARATUS

A press working method for forming by a press working apparatus, in a film material made of resin, a passage hole through which a fluid for a fuel cell flows, includes a placing step, a gripping step, and a piercing step. In the piercing step, a secondary die and a holder grip an outer peripheral portion of the film material. In the piercing step, a piercing punch punches out the film material is a state in which the press working apparatus does not contact an upper surface of the film material in an adjacent portion surrounding a portion to be punched out by the piercing punch.
