A cold working apparatus for forming a blank includes a first die and a second die. The first die has at least one die cavity and the second die has at least one die protrusion. The cold working apparatus press forms the blank placed between the first and second dies.

Cold working apparatus and a method for cold working a blank

A method for a hot press forming apparatus and a hot press forming apparatus () for forming a blank (), the hot press forming apparatus () comprising a first die () and a second die (), wherein the first die () has at least one die cavity (), and the second die () has at least one die protrusion (), wherein the hot press forming apparatus () is configured to, by means of the first and second dies (), press form the blank () placed between the first and second dies (). At least one of the first and second dies () has a draw radius (), wherein a member () is attached to a die () which has a draw radius (). At least a portion () of the member () is positioned adjacent to or on the draw radius (). The member () defines a first press forming surface (), and the die () holding the member () defines a second press forming surface () outside the first press forming surface (). The member () and the die (), which holds the member (), are configured such that during the same hot press forming, a first friction arises between the blank () and the first press forming surface () when the blank () is in contact with the member () and a second friction arises between the blank () and the second press forming surface () when the blank () is in contact with the die () which holds the member (), the first friction being lower than the second friction.

Hot press forming apparatus and a method for hot press forming a blank

A safety bar which provides protection, the bar having a generally trapezoidal, open cross-sectional shape. The cross-sectional configuration of the bar includes a central flange which is embraced by two webs each of which has a side-flange which extends outwardly on a respective side of the bar. The bar has an intermediate section between a first section thereof and a mounting section thereof at one of its ends. In the intermediate section, the central flange has generally a decreasing width and the webs a generally decreasing height towards the bar end.
