In order to provide a balanced bent lip disc, the applicant routinely had issues with rippling at an outer circumference edge of the lip. Due to the geometries involved in a 3½ inch disc bent to provide an outer lip of ½ inch at 45 degrees, 0.1145 of excess circumference is created thereby providing a ripple effect. The applicant discovered that simultaneously embossing the lip while bending the lip could reduce this rippling effect (and the outer circumference at the edge) by at least 75 if not 90 or 95% of a non-embossed lip bent in the same manner.

A Z-shaped attachment element for use in building construction is disclosed. The Z-shaped attachment element is made from a single piece of sheet metal that is first cut and then bent to form the Z-shaped cross-sectional profile. The Z-shaped attachment element comprises: an elongated upper flange; an elongated lower flange, wherein the upper and lower flanges are spaced apart and substantially parallel to each other; an elongated middle web section between, and connected to, the upper and lower flanges along respective upper and lower lengthwise bends (wherein the middle web section is diagonal in relation to the position of the upper and lower flanges, thereby defining a generally Z-shaped cross-sectional profile); and a plurality of notches formed along the lower lengthwise bend and into the lower flange and the adjoining middle web section, but not into the upper bend or the upper flange, of the Z-shaped sheet metal attachment element.

A process of producing a partially hardened metallic formed part comprises: heating a semi-finished product of hardenable hot-formable steel sheet to a hardening temperature; hot-forming the heated semi-finished product in a combined hot-forming cutting device into a three-dimensional formed part; cutting the formed part in the combined hot-forming cutting device; pressure-hardening the formed part in the hot-forming cutting device into a hardened formed part such that a first partial region is hardened by rapid cooling and that a second partial region of the formed part is heat-treated so as to comprise a greater ductility and a lower strength than the first partial region, wherein the operation of cutting the formed part takes place at least in one of the first and second partial region. A combined hot-forming cutting device can be used to produce a metallic formed part.

An emergency escape device to which an escape rope is adapted to be secured, includes a unitary, one-piece steel anchor plate; a semi-spherical projection pressed outwardly of the center of the plate, to form an outward projection; portions of the outward projection cut out to form a central opening in the plate, while leaving an arcuate, outwardly extending securement band as a remnant of the outward projection to enable attachment of a carabiner; a peripheral opening cut out to one side of the central opening for receiving at least one bolt for securing the device to a wall; and at least one peripheral opening cut out at to an opposite side of the central opening for receiving at least one bolt member for securing the device to a wall; and the plate being heat treated to impart greater strength thereto.

An apparatus for forming and sealing a duct member for use in an air handling system. At least one work station accommodates a work piece, which is generally a cylindrical tube.

A soldering nozzle (100) for selectively soldering assemblies by means of molten solder supplied through a soldering nozzle (100) from a solder bath. The soldering nozzle (100) is designed as a deep-drawn part. A method for the production of a soldering nozzle (100) is specified as well, including the provision of a blank (401); the drawing of the blank (401) through at least one female die (411, 421) by means of at least one male die (413, 422, 431) to produce an oblong shape (439) of locally annular or substantially annular cross-section, with a first end (436) corresponding to an action point of the male die (413, 422, 431) and a second end (437) corresponding to an introduction cross-section of the male die (413, 422, 431), the cross-section preferably increasing from the first end (436) towards the second end (437); and the formation of an opening (446) at the tip end (436).

A planar workpiece machining device has an upper tool and a lower tool that are movable toward each other in a reciprocation direction and in the opposite direction to machine a workpiece arranged therebetween. The upper tool has a clamping shaft, an upper main body, and a tool body arranged opposite the clamping shaft on the main body and having an upper bending edge. The lower tool has a lower main body, on which a counter tool body having a lower bending edge and a counter holder are provided. The lower bending edge is oriented facing the counter holder. The upper bending edge is stationary to the upper main body, and the lower bending edge is stationary to the lower main body. The upper bending edge is associated with an undercut on the tool body and the lower bending edge is associated with an undercut on the counter tool body.

A tool includes an upper tool having a clamping shaft and an upper main body that lie on a common positioning axis, a processing tool opposite the clamping shaft that has at least one processing edge that extends at least partially along a holding-down surface of the main upper body, a lower tool having a lower main body with a rest surface for the workpiece and a lower positioning axis oriented perpendicular to the rest surface, a counter tool body on the lower main body, the counter tool body having a counter roller with at least one counter edge opposite the at least one processing edge of the processing tool, and a processing device adjacent to the at least one counter edge that has at least one curved counter surface oriented in the longitudinal direction of the processing edge of the processing tool.

A process for manufacturing a metal part (10), is described said part extending in a first direction (Y) and having a section comprising a central member (14) and at least a first side member (16) extending in a second direction. The process comprises the following steps: supply of a metal blank (30); removing material from the blank so as to form an intermediate part (32) comprising the central member (14), a junction zone (12) and at least first (116) and second (118) intermediate side members, with a space (34) between the first and second intermediate side members; and hot forming (104) the intermediate part, including spreading the first and second intermediate side members apart by inserting a first punch (212) between said members.
