The punch is supported by a first cushion component. The bending blades each have an upper die component and a lower die component disposed facing each other in the press direction with an interval equal to a set compression amount in the range of 2% or more and 6% or less of the heights of the vertical wall portions and a second cushion component interposed between the upper die component and the lower die component, maintaining the interval, and contractible in the press direction. The cushion pressure of the second cushion component is lower than the cushion pressure of the first cushion component and has such cushion pressure that the second cushion component does not contract during the bend-forming of the vertical wall portions.

    Abstract: A sheet metal material is stamped into a formed shape having a side wall between a central portion and a flange portion. The central portion is held between an upper pad and a die, and the flange portion is held between an upper binder and a lower binder. A post-stamping compression force is applied along a length of the side wall of the formed shape. For example, application of the post-stamping compression force includes moving the lower binder relatively toward the upper pad, such as by delaying a return of the upper pad during a portion of a return of the lower binder. During application of the post-stamping compression force, an outward force is applied against an inner surface of the side wall to insure any bowing of the side wall is in an outward direction.

  • Patent number: 9333549
    Abstract: A prediction equation “R0/t?(2R/t+(2R/t+1)?f)/2(1?(1+2R/t)?f)” is derived which predicts that bendability-dominated fracture will not occur when the critical surface strain ?critical is not exceeded by a strain on the metal sheet surface causing the occurrence of ductility-dominated fracture that is obtained from the minimum curvature radius R0 of a press-forming mold and the critical strain ?f in a plane strain region in a forming limit diagram. The minimum curvature radius R0 of a mold required to prevent the occurrence of bendability-dominated fracture is estimated, and the mold is designed with a curvature radius that is not less than the curvature radius R0.

  • Patent number: 9327327
    Abstract: A method of manufacturing a pipe with different diameters along a longitudinal direction that has a small diameter portion, a large diameter portion, and a diameter-changing portion provided between the small diameter portion and the large diameter portion and is formed by press forming a blank made of a metal sheet includes press forming the blank with a U-shape forming die into a U-shaped formed part and press forming the U-shaped formed part with an O-shape forming die set into a circular cross-section formed part. A length of a vertical wall of the U-shape forming die is longer than a length of a vertical wall portion of the U-shaped formed part.

  • Patent number: 9328824
    Abstract: A cylinder member of an automatic transmission that includes an outer peripheral introducing portion having a shape that is able to be formed by ironing without forming and trimming of a flange portion which was conventionally required for forming an outer peripheral introducing portion. Therefore, steps required for forming the flange portion are omitted, and the number of steps for manufacturing the cylinder member is reduced. Without using a large-scale press machine such as a progressive press and a transfer press, the cylinder member is manufactured by a smaller-sized press machine, thereby reducing equipment investment required for manufacturing the cylinder member.

  • Patent number: 9216448
    Abstract: The invention relates to a drawing press (10) having a first ram (17) and a second ram (18). The first ram (17) is moved in a working direction (A) by an electromotive first ram drive (25) and the second ram (18) by an electromotive second ram drive. The drawing press (10) also has a coupling means (35) which can be switched between an uncoupling state and a coupling state. In the uncoupling state, the two rams (17), (18) can move independently of one another in the working direction (A). In the coupling state, the coupling means (35) ensures that a relative movement between the two rams (17, 18) is prevented. The drawing press (10) can therefore be operated as a single-acting or double -acting press.

  • Patent number: 9192976
    Abstract: An apparatus for forming a container body from a metal blank has a ram, a blank holder, an annular die, a die holder, an insert and a plurality of ironing rings. The ram is centered about a longitudinal axis. The blank holder has an aperture through which the ram passes. The annular die is substantially axially aligned with the ram and adapted to allow the ram to pass therethrough. The die holder has a recessed portion adapted for receiving the annular die therein. The recessed portion has an annular, arcuate concave surface. The insert is located within the recess between the annular, arcuate concave surface and the annular die. The insert has a surface for supporting the annular die thereon opposite an annular, arcuate, convex surface in operative engagement with the annular, arcuate concave surface and swivelable thereon. The ironing rings are substantially axially aligned with the ram.

  • Patent number: 9085027
    Abstract: A method of manufacturing a tubular member having a non-constant thickness by ironing at least a portion of the tubular material. The ironing apparatus can have a punch and a die, and the die can have a convex and concave side surface opposing the punch. The method can include bending an axial end portion of the tubular material to form a bent portion. The tubular material can then axially engage the die at the bent portion, and then the punch can be moved relative to the die to iron at least a portion of the tubular material.

    Abstract: A method for producing a pot-shaped component from a flat blank. The method comprises the following steps: a) shaping the flat blank in at least one deep-drawing step to form a pot-shaped raw component having a substantially flat bottom area and a circumferential frame, b) shaping said pot-shaped in a tool having a conically tapered die that applies shear to the circumferential surface of the frame in the axial direction against the conically tapered die. In step b), the bottom area is clamped at between an ejector and a hold-down means and the conically tapered die surrounds the bottom area of the raw component radially on the outside and extends in a diameter-reducing manner in the tool stroke.
