摘要： A hot press-forming method includes a forming step that clamps a steel sheet heated to a temperature not less than an austenite transformation temperature and press-forms the steel sheet into a desired shape by causing a forming concave of a die and a convex of a punch to be close to each other. A formed portion has side and top portions that merge. The side portion rises up from an inner circumferential edge of a flange portion having been clamped by the die and the blank holder. A cooling step cools a region of the steel sheet after the heating step has been completed and before the forming step is completed. The particular region is along an inter-edge area formed between an opening circumferential edge of the forming concave and a top circumferential edge of the forming convex before the forming step is completed.

摘要： A can forming machine includes a can body holder in which the can body does not fall at an unexpected time. A knockout unit has a knocking out piston which is disposed to be movable in a depth direction of a recess and is provided to be displaceable between a protruding position at which the knocking out piston protrudes into the recess and an recessed position at which the knocking out piston exits the recess, and a cylinder which supports the knocking out piston to be displaceable. At a discharge position, at which the formed can body is discharged from the recess of the can body holder, a piston displacing unit, which displaces the knocking out piston from the recessed position toward the protruding position, is provided adjacent to the other surface side of the base.

摘要： A yoke housing includes a tubular case and a flange. The tubular case is formed from a metal sheet in a drawing process. The flange is formed at an end of the tubular case. The flange has a width in the lateral direction that is equal to the outer diameter of the tubular case. The flange has a base including beads and a thick portion. Each of the beads is formed by compressing the base. A portion of the base in which the beads are not formed defines a thick portion. The thick portion is located at a middle portion of the flange in the lateral direction. The beads are located on opposite sides of the thick portion in the lateral direction.

摘要： The present invention suppresses deterioration in the corrosion resistance of a worked portion resulting from working cracks in a Zn-based plated layer (3) in a workpiece (2) formed into a predetermined shape by performing plastic working on a Zn-based plated steel sheet (1) coated with a Zn-containing metal as a raw material. That is, plastic working is performed on a raw material that is a Zn-based plated steel sheet (1) to obtain a workpiece (2) having a predetermined shape, and thereafter, pressurization processing is performed on a worked portion in a sheet thickness direction to deform the plated metal, thus decreasing the width of working cracks in the plated metal. Accordingly, it is possible to reduce the deterioration in the corrosion resistance of the worked portion of the Zn-based plated workpiece.

摘要： A method produces a press-molded article having a hat shaped cross-section with flanges at both sides, a top plate, vertical walls at both sides, and having a shape curved in the vertical direction to an inverted checkmark shape along the longitudinal direction when the molded article is viewed from a side face with the top plate section on the top side. An intermediate molded body is formed by drawing a metal stock sheet into an intermediate shape, and after preparing the outside shape of the intermediate molded body by trimming, drawing is subsequently performed to form the final shape.

摘要： The drawing press (10) according to the invention has for driving its ram (15) a directionally reversing gear mechanism (22, 54), for example a coupling gear mechanism, and at least one servomotor (23). The servomotor (23) passes through the reversal point (Ut) of the ram movement, which is predetermined by the kinematics of the coupling gear mechanism, for example the extended position of an eccentric drive. During the closing of the die (18), that is to say during a press stroke, the servomotor (23) is activated in such a way that it first passes through this reversal point (Ut), then stops, reverses and then passes through it once again, in order to open the die (18) again. Consequently, the braking to a standstill and re-acceleration of the servomotor for the upper ram (15) takes place while the actual drawing operation is still or already being performed, i.e. during the forming of the metal blank, which significantly reduces the cycle time.
