An electrostatic oiling system for use with single blanks in batch systems having an open spray chamber without the need for a negative vacuum chamber. Further, the provided electrostatic oiling system may utilize induction beams and a charge wall that allows for utilization of a smaller vacuum system. Further, the provided electrostatic oiling system may provide variable blank coverage without the need for metered pumps.

Disclosed is a tube bending system for forming a hairpin tube, the tube bending system including: a supply of lubricant; a supply of atomizing medium; a bend mandrel, the bend mandrel comprising: a mandrel body and a mandrel head, the mandrel head being positionable within a length of a tube to be bent, the mandrel head including a downstream end with an orifice configured for injecting lubricant into the tube.

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.

An apparatus for forming a metal workpiece having a first surface is described herein. The apparatus includes a trough containing a liquid. The apparatus also includes a support for positioning the metal workpiece in an impact-receiving position. In the impact-receiving position, the first surface is submerged in the liquid.
