Abstract
A press apparatus includes a lower die cam base slidably disposed inside of a lower die, and having a lower die pad connected to a upper portion of the lower die cam base; an upper die pad mounted under an upper die through a cushion spring at a position corresponding to the lower die pad; and an upper die cam slide having a cam slide surface formed at a lower portion, a cam surface formed at an upper portion, and a cam steel mounted to the upper die cam slide.
Claims12
A press apparatus, comprising:
- a lower die cam base slidably disposed inside of a lower die, wherein a lower die pad is connected to an upper portion of the lower die cam base;
- an upper die pad mounted under an upper die through a cushion spring at a position corresponding to the lower die pad;
- an upper die cam slide having a cam slide surface formed at a lower portion thereof, a cam surface formed at an upper portion thereof, and a cam steel mounted thereto;
- and
- a holding unit mounted to the lower die cam base and the upper die cam slide for holding a flange surface of a panel during press forming, wherein the holding unit comprises:
- a lower holding pad mounted to the lower die cam base for holding an inner portion of the flange surface of the panel;
- and
- an upper holding pad mounted to the upper die cam slide for holding an outer portion of the flange surface of the panel corresponding to the lower holding pad,
- wherein the lower holding pad and the upper holding pad are mounted to the lower die cam base and the upper die cam slide, respectively, interposing a pad cushion spring between the lower holding pad and the lower die cam base, and between the upper holding pad and the upper die cam slide for supplying elastic force to the lower holding pad and the upper holding pad, respectively.

A press apparatus for press forming a panel inserted into an upper die and a lower die, the press apparatus comprising:
- a lower die cam base slidably disposed inside of the lower die and having a forming shape corresponding to a lower surface of a lower portion of the panel to be formed;
- a connecting block contacting the lower die cam base and slidably disposed within the lower die;
- a lower die pad connecting upper portions of the lower die cam base and the connecting block and having a forming shape corresponding to a lower surface of an upper portion of the panel to be formed;
- a lower die driver mounted under the upper die to selectively push the lower die cam base through the connecting block;
- an upper die pad mounted under the upper die through a cushion spring at a position corresponding to the lower die pad and having a forming shape corresponding to an upper surface of an upper portion of the panel to be formed;
- a cam guide block formed to the lower die apart from the lower die cam base and having a cam guide surface that slants to the lower die cam base;
- an upper die cam slide having a cam slide surface corresponding to the cam guide surface of the cam guide block, a cam surface slant opposite direction of the cam slide surface, and the upper die cam slide having a cam steel mounted toward the lower die cam base thereto;
- and
- a holding unit mounted to the lower die cam base and the upper die cam slide for holding a flange surface of the panel during press forming, wherein the holding unit comprises:
- a lower holding pad mounted to the lower die cam base for holding an inner portion of the flange surface of the panel;
- and
- an upper holding pad mounted to the upper die cam slide for holding an outer portion of the flange surface of the panel corresponding to the lower holding pad,
- wherein the lower holding pad and the upper holding pad are mounted to the lower die cam base and the upper die cam slide, respectively, interposing a pad cushion spring between the lower holding pad and the lower die cam base, and between the upper holding pad and the upper die cam slide for supplying elastic force to the lower holding pad and the upper holding pad, respectively.
