Abstract

A method for a hot press forming apparatus and a hot press forming apparatus (102; 202) for forming a blank (104), the hot press forming apparatus (102; 202) comprising a first die (106; 206) and a second die (108), wherein the first die (106; 206) has at least one die cavity (110; 210), and the second die (108) has at least one die protrusion (112), wherein the hot press forming apparatus (102; 202) is configured to, by means of the first and second dies (106, 108; 206, 108), press form the blank (104) placed between the first and second dies (106, 108; 206, 108). At least one of the first and second dies (106, 108; 206, 108) has a draw radius (116; 216), wherein a member (118; 218) is attached to a die (106; 206) which has a draw radius (116; 216). At least a portion (119; 219) of the member (118; 218) is positioned adjacent to or on the draw radius (116; 216). The member (118; 218) defines a first press forming surface (120; 220), and the die (106; 206) holding the member (118; 218) defines a second press forming surface (122; 222) outside the first press forming surface (120; 220). The member (118; 218) and the die (106; 206), which holds the member (118; 218), are configured such that during the same hot press forming, a first friction arises between the blank (104) and the first press forming surface (120; 220) when the blank (104) is in contact with the member (118; 218) and a second friction arises between the blank (104) and the second press forming surface (122; 222) when the blank (104) is in contact with the die (106; 206) which holds the member (118; 218), the first friction being lower than the second friction.

Description

technical field [0001] Aspects of the present invention relate to a thermocompression forming apparatus for forming a billet, wherein the thermocompression forming apparatus includes a first die and a second die. The first mold has at least one cavity and the second mold has at least one mold projection, the mold projection of the second mold being complementary to the cavity of the first mold. The hot press forming apparatus is configured to press form a blank placed between the first die and the second die through the first die and the second die. Furthermore, aspects of the invention relate to a method for hot press forming a billet. Background technique [0002] Hot-pressed metal parts, such as aluminum parts, are commonly used in the automotive industry for various parts of cars, such as door sills, bumpers, support elements and structures, etc. Other fields of application are also possible. When hot press forming a blank between two dies to form a metal part, the bl...
