Abstract
The present invention relates to a press-forming tool having a top die and a bottom die, which can be moved toward one another, forming a forming cavity between the top die and the bottom die when the press-forming tool is closed, wherein a die clamping plate is arranged on a press ram and/or on a press table, wherein a top die or bottom die, which can be moved relative to the die clamping plate, is supported on said plate while incorporating at least one resilient adjusting element.
Claims10
A press-forming tool, comprising:
- a top die and a bottom die movable toward one another, and forming a forming cavity between the top die and the bottom die when the press-forming tool is closed;
- a die clamping plate arranged on a press ram or on a press table;
- at least one resilient adjusting element arranged in the die clamping plate;
- and
- sliding blocks coupling at least one of the top die and the bottom die to the die clamping plate in such a way that said at least one of the top die and the bottom die is capable of relative movement on the die clamping plate,
- wherein said at least one of the top die and the bottom die is movable relative to the die clamping plate, and is supported on the die clamping plate by said at least one resilient adjusting element,
- wherein each of the sliding blocks is I-shaped and has a guiding portion and an abutment portion, and the sliding blocks are parallel to each other over an entire length of the die clamping plate, and
- wherein the die clamping plate comprises a plurality of elongated clamping slots for inserting the sliding blocks.

A press-forming tool, comprising:
- a top die and a bottom die movable toward one another, and forming a forming cavity between the top die and the bottom die when the press-forming tool is closed;
- a die clamping plate arranged on a press ram or on a press table;
- at least one resilient adjusting element, wherein a portion of the at least one resilient adjusting element is arranged in the die clamping plate and another portion of the at least one resilient adjusting element partially extends from an upper surface of the die clamping plate;
- and
- sliding blocks coupling at least one of the top die and the bottom die to the die clamping plate in such a way that said at least one of the top die and the bottom die is capable of relative movement on the die clamping plate,
- wherein said at least one of the top die and the bottom die is movable relative to the die clamping plate, and is supported on the die clamping plate by said at least one resilient adjusting element,
- wherein each of the sliding blocks is I-shaped and has a guiding portion and an abutment portion,
- wherein the sliding blocks are parallel to each other over an entire length of the die clamping plate,
- wherein the die clamping plate comprises a plurality of elongated clamping slots for inserting the sliding blocks, and
- wherein the press-forming tool is a hot-forming and press-hardening tool and further comprises cooling passages formed in the top die and/or the bottom die, the cooling passages allowing a coolant/cooling fluid to pass through, allowing press hardening to be performed.
