Abstract
The invention relates to a method for producing a toe cap (10) and such a toe cap itself. The toe cap comprises at least one end wall (12) extending in an arch shape and a cover wall (14) extending therefrom that covers the toes on the upper side, wherein the cover wall and the end wall have a base wall thickness G and areas separated from sections of the walls, such as webs in the walls, have a thickness D with 0≤D<W, wherein the difference between the volume of the toe cap with areas filled to the base wall thickness W and the volume of the toe cap with the areas of lesser thickness is 5% to 35%, and/or the difference between the area of the toe cap with filled areas and the outer surface of the toe cap without the areas is 20% to 60%.
Claims11
A method for producing a toe cap, comprising the steps of:
- step 1) specifying a master cap that has at least one defined parameter that is characteristic of a toe cap to be produced,
- step 2) simulating a virtual cap corresponding to the master cap according to a simulation method,
- step 3) simulating the virtual cap in such a way that a value of a first simulated characteristic parameter corresponding to the defined characteristic parameter corresponds to that of the defined characteristic parameter of the master cap or lies within a predetermined tolerance range thereof,
- step 4) modifying the structure of the virtual cap,
- step 5) calculating the value of the simulated characteristic parameter of the structurally modified virtual cap and comparing it with the value of the characteristic parameter according to step 1) and/or step 3),
- step 6) modifying the structure of the virtual cap again, if
- a) according to step 5), a deviation is determined that lies outside a predetermined tolerance range, and then recalculating the characteristic parameter, or
- b) if the characteristic parameter lies within the tolerance range, if the structure modified according to step 4) does not meet a specified criterion,
- step 7) if necessary, repeating process steps 4) to 6) until the calculated value of the characteristic parameters lies within the specified tolerance range, and
- step 8) producing the toe cap based on the virtual cap having the modified structure, for which the simulated characteristic parameter lies within the predetermined value range of the first simulated characteristic parameter;
- wherein modifying the structure of the virtual cap in step 6 is carried out by at least one of:
- creating and/or modifying a variety of through openings by material removal,
- thickening of material,
- forming or modifying areas in the virtual cap delimiting through openings or depressions.
