A curved part 10 having a hat-shaped cross section is produced by press-forming without causing cracks and wrinkles. When producing a curved part 10, which is made up of a top plate 11, vertical walls 12a and 12b extended in parallel with each other along ridgelines 14a and 14b of the top plate, and outwardly directed flanges 13a and 13b which connect to leading edges of the vertical walls, and has a generally hat-shaped cross section, by press forming, the metal material sheet 601 is interposed and constrained by the die 502 and the blank holder 505 and is press-formed while the metal material sheet 601 being interposed and constrained by the pad 503 and the punch 504.

A suspension member having an arm member and a ball joint section. The ball joint section having an opening receiving a press fit ball joint. The material of the ball joint section having a smaller material thickness than the material of the arm member. The ball joint section connected to the arm member.

A frame system for a building structure includes beam members. Each beam member comprises two opposed, parallel flanges. A web is interposed between the flanges. Spreader members comprise two opposed, parallel side flanges, a web interposed between the side flanges and two opposed end flanges bridging the side flanges at respective terminal ends of the web. The beam members and the spreader members are configured to be fastened to each other to form a frame assembly.

An extension support member includes a bracket or web having a first planar portion or leg, a second planar portion or leg, an acute, concave angle between the first planar portion or leg and the second planar portion or leg, and a bend or backbone joining the first planar portion or leg to the second planar portion or leg. The extension support member also includes is a first mounting portion or tab joined to the second planar portion or leg via the bend or backbone at a first, convex obtuse angle and a second mounting portion or tab joined to the first planar portion or leg via the bend or backbone at a second obtuse, convex angle. The first mounting portion and the second mounting portion are located at opposite ends of the bracket or web.

A method for machining includes providing a component or a semifinished part which has a main body with a first surface and with a first surface coating provided on the first surface. The method also includes notching the component or the semifinished part on the first surface coated with the first surface coating. The method also includes severing, perforating or trimming the component or the semifinished part along the notch. At least a part of the first surface coating which is notched in the process is maintained along notch surfaces.

Providing a manufacturing method for a vehicular arm component that can further increase material yield.

Including an expanding process S05 of pressing a pressurized portion P8 provided in a plane of a workpiece W in a Z direction to expand an X-directional width of the workpiece from a first width X1 to a second width X2, and a separating process S06 of cutting off the workpiece having an X-directional width expanded to the first width from a processed material M.

A processing device is provided which feeds a long plate body from an upstream side to a downstream side and sequentially carries out a press work including a blanking work to the long plate body. The processing device includes a plurality of stages provided along a feed direction of the long plate body, which has a die that applies the press work to the long plate body and a plurality of lifters provided along the feed direction of the long plate body which have lift-up parts that lift up the long plate body from the die. In the plurality of lifters, clearances by the lift-up parts of the lifters arranged in the downstream side are set to be larger than the clearances by the lift-up parts of the lifters arranged in the upstream side.

A method of forming one or more tie rods that includes flattening a main body of a wire in a first selected plane to form a flattened main body, further flattening selected portions of the flattened main body in a second plane perpendicular to the first plane to form one or more break back regions, and then passing the wire through a punch press machine to form one or more coined regions in one or more ends of the wire, thus forming the tie rod.

The invention relates to a method for the forming of a workpiece, in particular a blank, composed of sheet steel, in which method the following steps are performed in succession: providing a workpiece composed of multiple steel layers which have been non-detachably connected to one another by roll-bonding and of which at least two steel layers have a different strength and/or elongation at fracture, heating the workpiece, and subjecting the workpiece to hot forming. To ensure a high strength and at the same time the easiest possible formability, the invention proposes that at least one section of the hot-formed workpiece is hardened, and that the workpiece is subsequently subjected to cold forming in the region in which the hardening has been performed. The invention also relates to a corresponding workpiece.

A method for manufacturing a metal element includes performing press processing and punching processing on a band plate-shaped metal element material having a constant cross section by a mold with a main punch in contact with a rear surface of the metal element and a counter punch in contact with the front surface thereof. The main punch or the counter punch has protrusion portions which are in contact with at least a part of the ear portion or the body portion to form a recessed portion, and a bulging portion bulging in the longitudinal direction from the radial direction inner edge of ear portions of the metal element or the radial direction outer edge of a body portion thereof, which is formed by the material extruded from the recessed portion by the protrusion portion.
