Abstract: In a method for producing a cooling plate, a workpiece in the form of a flat material blank with uniform material thickness is precisely centered in a tool. A substantially radially extending flat peripheral edge of the workpiece is formed by an outer punch of the tool, as the workpiece is held down by an inner punch of the tool and the outer punch is pressed against the peripheral edge to thereby reduce the material thickness of the peripheral edge. Pins are formed on a coolant-swept effective surface of a base of the workpiece by the inner punch through pressing in cooperation with pin forming openings of the tool as the outer punch is held down, such that the pins protrude approximately perpendicular beyond the base and are surrounded by the peripheral edge.

Abstract: In a method for the production of a cooling plate from a material having thermal conductivity, a workpiece in the form of a flat material blank with uniform material thickness is placed into a tool. The workpiece is pressed in a first stage by an inner punch of the tool to form in cooperation with pin forming openings of the tool pins upon an effective surface swept by the coolant, as the workpiece is held down by an outer punch of the tool, such that the pins protrude approximately perpendicular over a base area of the workpiece. In a second stage, the workpiece is pressed by the outer punch such as to form an essentially radially extending, flat peripheral edge of reduced material thickness in surrounding relation to the pins, as the workpiece with the formed pins is held down by the inner punch of the tool.

Abstract: A resistance welding electrode includes a shaft-shaped holder and an electrode part in the form of an electrode cap or a pin electrode which are non-positively connected via tapered surfaces. Furthermore, cooling bores are also present. In such a resistance welding electrode the tapered cone angle is in a region of about 1 degree to 3 degrees and the holder and the electrode part are connected such that the holder and the electrode part are further in axial contact with each other via a radial surface contact, and the edge of the electrode part facing the holder is restrained in an associated reception recess on the holder side by means of reduction.

Abstract: The invention relates to a resistance welding electrode (1) having a shaft-shaped holder (2) and an electrode part (3; 3?) in the form of an electrode cap (5) or a pin electrode (7) which are non-positively connected via tapered surfaces. Furthermore, cooling bores (9) are also present. In such a resistance welding electrode (1) the tapered cone angle is in a region of about 1 degree to 3 degrees and the holder (2) and the electrode part (3; 31) are connected such that the holder (2) and the electrode part (3; 3?) are further in axial contact with each other via a radial surface contact (6), and the edge (15) of the electrode part (3; 3?) facing the holder is restrained in an associated reception recess (16) on the holder side by means of reduction.
