A swaging device includes a top die and a bottom die that can move in a vertical direction between an open position and a closed position. Each die includes an inclined surface, and the device further includes swaging elements each having a complementary inclined surface that is in contact with the inclined surface of each die, both in the open position and in the closed position. The swaging elements are arranged opposite one another such that in at least any position other than the open position, they are in contact by certain non-inclined surfaces opposite the complementary inclined surfaces.

[Object] To provide a press-molding apparatus capable of appropriately thickening a vertical wall portion while preventing the occurrence of buckling. [Solution] Provided is a press-molding apparatus configured to mold a press-molded product by performing press working on a work, the press-molding apparatus including: a support member that supports the work with a first thickness having a hat-shaped cross-section or a U-shaped cross-section; a punch member that moves relative to the support member to execute press working so as to reduce a height of a vertical wall portion of the work and thicken the vertical wall portion to a second thickness; and a pad member that faces the support member with the vertical wall portion to be thickened placed therebetween, the pad member being biased by a biasing member and having its distance to the support member kept equal to or smaller than the second thickness during the press working.

A machine tool apparatus for a press brake, folding press or punch press system includes a tool holder body having a receiving portion configured for selective engagement with a coupling end of a machine tool. The apparatus also includes a magnetic coupling assembly comprising one or more magnetic elements configured to generate a magnetic coupling adapted for the selective engagement of the tool holder body with the coupling end of the machine tool. In some embodiments, the apparatus may further include an actuator configured to manipulate at least one of the magnetic elements to modulate the strength of the magnetic coupling for selective engagement and disengagement of the tool holder body with the coupling end of the machine tool.

A method for texturizing a workpiece uses a die assembly installed within a press having a press ram. The method includes (a) delivering the workpiece onto a center die plate; (b) forcing the press ram against an upper die plate mounted above the center die plate to descend a first contact surface associated with the upper die plate and a plurality of blades mounted to the upper die plate toward the center die plate; (c) actuating horizontal movement of the blades; (d) driving the blades down into the workpiece; and (e) contacting the first contact surface to a second contact surface associated with the center die plate to descend the center die plate in unison with the upper die plate.

A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations evenly spaced across the bolster and ram including aligned tooling piece holders on the bolster and ram, cylindrical die cases in the tooling holders on the bolster and cylindrical tool cases in the tooling holders on the ram, the tooling cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the mechanism including a cam and a cam follower radially outward of imaginary outward projections of the associated tooling cases, the cam follower being arranged to be activated by forward motion of the ram towards the bolster, the mechanism including a tool for forming the blank by applying a sideways force on the blank.

A manufacturing method of press-molded article of the present invention comprises a step of placing a member to be pressed in a press molding apparatus and a step of pressing a flat plate portion of the member to be pressed by bringing a first press portion and a second press portion closer to each other. A first opposing surface and a second opposing surface, while facing to each other, keep in contact with the flat plate portion during pressing. In the press step, a thick part is formed on the flat plate portion by allowing a part of a material of the flat plate portion to flow, in a press direction, into a thickened portion-forming section formed on the first opposing surface. The second opposing surface is moved to the press direction as the flat plate portion is pressed by the first press portion and the second press portion.

A shaping method making use of shaper tooling suitable for high-temperature shaping of a preformed metal part having two side fins extending from a nose, the method including putting the preformed metal part into place in a first bottom die of the tooling, holding the preformed metal part in a first determined position with a first movable central insert, forming one of the side fins of the preformed metal part into its final shape in alignment with the nose by moving with a first movable top die, turning over the preformed metal part, putting the preformed metal part into place in a second bottom die of the tooling, holding the preformed metal part in a second determined position with a second movable central insert, and shaping the other side fin into its final shape in alignment with the nose by moving with a second movable top die.

The present invention provides a method of near-net-shape forged molding of the coupler knuckle of the railway vehicle. The present invention solves the problems that the manufacturing the forged coupler knuckle is difficult, and the process is complex, etc. The method of the present invention includes the following steps: material preparation, heating, blank prefabrication, pre-forging, closed-die forging, quenched-tempered heat treatment using waste heat, finish machining, flaw detection, etc. With the closed-die forging technology, the near-net-shape molding of the coupler knuckle can be achieved. The energy and the material are saved. The contour shape and the size do not need to be machined. The use ratio of the material can reach more than 92%. Moreover, during the entire molding, the workpiece is in the three-dimensionally stressed state all the time. The product has a dense texture, a high toughness, a good fatigue resistance, and a long lifetime.

A forming device and a method for forming an inner rim of an annular round blank. The forming device has a lower tool with a movable die and an upper tool arranged opposite the lower tool along a working axis A. By means of the die, the annular round blank is moved out of a transport plane T and into a forming position U towards the upper tool and into the interior of a holding sleeve. Subsequently, the inner rim is formed with the aid of a forming tool. After forming, the annular round blank is moved out of the forming position U and back into the transport plane T by means of the lower tool and/or the upper tool. The forming device and the forming method can occur while the round blanks are being fed to an embossing station while being transported by a revolving table.

A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations evenly spaced across the bolster and ram including aligned tooling piece holders on the bolster and ram, cylindrical die cases in the tooling holders on the bolster and cylindrical tool cases in the tooling holders on the ram, the tooling cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the mechanism including a cam and a cam follower radially outward of imaginary outward projections of the associated tooling cases, the cam follower being arranged to be activated by forward motion of the ram towards the bolster, the mechanism including a tool for forming the blank by applying a sideways force on the blank.
