A method of making a motor vehicle component by hot-forming, hot-cutting, and press-hardening a plate made of a hardenable steel sheet alloy, heating to a temperature greater than Ac1, inserting in a combined forming and cutting tool, fixing the inserted plate in the forming and cutting tool using a stamp which is arranged in the inner region of the tool, at least partially circumferential edge cutting before beginning the forming operation or during a time period of up to 50% of the forming progression and/or at least 20% of the press stroke prior to the bottom dead center position, and hot-forming in a press stroke with the edge cut and optional press-hardening.

A method for manufacturing a locking arm of a carrier connecting rod includes four steps to press a metal sheet via a first stamping die and a second stamping die to form the metal sheet to include a front section, a bent middle section and a rear section. A stopper is formed to the front section, and a recessed area is formed to one side of the bent middle section. A positioning hole is defined through a center of the recessed area. A guide surface is formed to the bent middle section opposite to the recessed area. The locking arm is pivotably connected to the extendable tube of the carrier connecting rod, and the protrusion of the spring member in the extendable tube is guided by the guide surface to be retractably engaged with the positioning hole. The locking arm is manufactured at low cost and has better structural strength.

A sheet roll forming method includes an uncoiling step for uncoiling a coil by an uncoiler provided at a start of a process line, a straightening step for straightening the coil from the uncoiler to be a flat panel, a piercing step for forming holes for various purposes in the panel fed from the straightening step by a piercing press, a sheet roll forming step for cutting the panel to be a sheet with a predetermined dimension by a running cutter and for successively bending the cut sheet to be a shaped beam by a multi-stage roll forming unit, and a bending step for curvature forming the shaped beam to be a shaped product by a round bender.

A flame port structure for burning a gas includes a first continuous spiral strip, a second continuous spiral strip and a first outflow passage. The first continuous spiral strip has a first side edge, a second side edge and a first plurality of annular segments, and the second continuous spiral strip has a third side edge, a fourth side edge and a second plurality of annular segments, wherein each of the first plurality of annular segments and each of the second plurality of annular segments respectively have two first longitudinal opposite surfaces and two second longitudinal opposite surfaces. The first outflow passage has a first defining wall formed on each of the first respective longitudinal surfaces from the first side edge to the second side edge. The first outflow passage is structured so that the gas produces a specific combustion.

The invention relates to a method for machining a sheet-metal profile 1, wherein the sheet-metal profile 1 is trimmed in a multi-stage cutting process and a cutting edge 2 is produced. Here, pre-cutting is firstly performed on the sheet-metal profile 1, whereby a free space 3 is generated. Stamping of the sheet-metal profile 1 is subsequently performed, wherein the thickness d of the sheet-metal profile 1 along the cutting edge 2 to be produced is reduced. Subsequently, the cutting finishing of the sheet-metal profile 1 is performed, wherein, in particular, cutting is performed in the opposite direction to the stamping of the outline of the finished contour, and the cutting edge 2 is generated.

A tool may be used to shape and/or partially press harden a workpiece. In some examples, the tool may comprise a main body having a surface, as well as a heat conducting system containing a thermal medium. The heat conducting system is integrated in the tool in such a way that, for the heating of the surface, a heat radiating from a heat source is conducted by means of the heat conducting system to the surface of the main body. Further, the heat conducting system may comprise a thermal oil or a melt as the thermal medium. The surface of the main body may be configured to face the workpiece during the shaping or partial press hardening of the workpiece.

Methods and apparatus to shape a workpiece are disclosed herein. An exemplary apparatus includes a first die and a second die movable relative to the first die. The apparatus also includes a punch assembly movable relative to the second die and the first die during a stroke cycle of the second die to a position adjacent a workpiece disposed between the second die and the first die. The punch assembly includes a punch to be actuated to pierce the workpiece when the punch assembly is in the position adjacent the workpiece.

A method for manufacturing a separator that can effectively prevent warpage is provided. A method for manufacturing a separator according to an embodiment includes disposing a separator material 10 including a flow path forming region 11 between a first upper die 51 and a first lower die 50, and pressing the separator material 10 using the first upper die 51 and the first lower die 50 to thereby form a first recessed and projected shape 13 in the flow path forming region 11 and form a second recessed and projected shape 14 outside the flow path forming region 11.

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.
