A producing method of the press formed product includes a preparation step of preparing a metal sheet as a starting material; and a press working step of performing press working on the starting material. The press working step includes: during a time period from when pushing-in of the starting material into the die by the punch is started or immediately thereafter until the pushing-in of the punch with respect to the die reaches a predetermined distance short of a bottom dead point for the pushing-in, holding the pad at a position distant from the punch by the predetermined distance; when the pushing-in of the punch with respect to the die reaches the predetermined distance short of the bottom dead point, receiving the pad in the die; and continuing the pushing-in of the punch with respect to the die and the pad to the bottom dead point.

A method of manufacturing a hot press-formed part by hot pressing a coated steel sheet formed with a Zn—Ni plating layer on a surface of a steel sheet includes: heating the coated steel sheet to a temperature range of Ac.sub.3 transformation temperature to 1000° C.; cooling the coated steel sheet to 550-410° C. at a cooling rate of 100° C./s or higher by squeezing the coated steel sheet with a press tool for cooling having flat surfaces configured to contact the coated steel sheet; press forming the coated steel sheet with a tool of press forming to obtain a formed body, the press forming being initiated within 5 seconds after the cooling while the temperature of the coated steel sheet is 550-400° C.; and quenching the formed body, while squeezing the formed body with the tool of press forming and holding at its press bottom dead center, to obtain a hot press-formed part.

Apparatus for processing a sheet-metal workpiece includes a press tool including a bottom die and top die. A press includes a platen which receives the bottom die, and a ram which receives the top die. The press tool is protected by a protective system which detects an idle stroke and includes an adjustable spacer assembly to prevent collision between the top and bottom dies.

A container, such as a beverage or food can is provided, which includes a first sidewall, a second sidewall and a bottom portion extending between the first and second sidewalls. The material of the bottom portion is stretched relative to the first sidewall and the second sidewall to form a thinned preselected profile, such as a dome. The material of the container at or about the dome has a substantially uniform thickness. The container is formed from a blank of material, which has a base gauge prior to being formed. After being formed, the blank of material of the container at or about the dome has a thickness less than the base gauge. Tooling having a clamp bead, or a progressive clamp bead, for selectively forming a blank of material into a container, as well as an associated method are also disclosed.

An object to provide a press-forming method that can efficiently suppress springback and easily specify a position where a springback reduction effect by rigidity improvement is large, and the press-forming method used in producing a press-formed product having a predetermined shape by press-forming a sheet material, the method including: a first process that repeatedly performs a springback analysis, while changing a position to be restricted, to specify a position where a springback reduction effect by rigidity improvement is large; a second process that performs a rigidity improvement measure on a position of the sheet material corresponding to the position of the formed-product model specified in the first process; and a third process that produces the press-formed product by press-forming the sheet material on which the rigidity improvement measure has been performed.

A hot press forming die includes a die main body (2) made of alloy tool steel, and a number of forming projections (3) projecting on the die main body and configured to form a forming surface (5) that comes into contact with a heated metal plate material that is an object to be formed and form a refrigerant passage through which a cooling medium flows. The die main body includes a first forming portion (14) in which the forming surface is formed to extend in a direction intersecting a forming direction of the metal plate material, a second forming portion (15) in which the forming surface is formed to extend in the forming direction, and a third forming portion (16) configured to connect the first forming portion and the second forming portion such that the forming surface becomes a convex surface. The forming projection provided on the third forming portion is formed to be a projecting strip extending between the first forming portion and the second forming portion.

It is possible to provide a hot press forming die for which forming convex portions with a high hardness can easily be formed.

A die press-forms a tailor welded blank (12A) in a heated state, the tailor welded blank being formed by welding a first plate portion (34) made of a first metal plate material and a second plate portion (35) made of a second metal plate material thicker than the first metal plate material while making the first plate portion and the second plate portion abut against each other. The die includes a refrigerant passage through which a refrigerant flows, and at least one refrigerant ejection path (64) having one end connected to the refrigerant passage and the other end opening to a forming surface of the die (lower die 13). The die includes a first forming surface (51), and a second forming surface (52), farther apart from a forming surface of another die than the first forming surface (51), for forming a step (53) together with the first forming surface (51). The other end of the at least one refrigerant ejection path (64) opens near the step (53) on the second forming surface (52) between the first forming surface (51) and the second forming surface (52). It is possible to provide a die for hot press forming, which can perform quenching even for the step portion of the metal plate material and increase hardness.

A method for producing a pressed component and for designing a die applicable even when a component shape that cannot be formed without being greatly drawn is produced. A method for producing a component for press forming a metal sheet into a final component shape through two or more press steps including a step carried out by drawing includes: determining the inflow amount of a material required for forming the metal sheet into the final shape based on the increase in the cross-sectional line length of the shape with respect to the line length of the sheet before forming in the press forming of the sheet into the final component shape by a step; and distributing the determined inflow amount of the material to each step including a final press step, and determining a preformed shape after forming in steps other than the final step based on the inflow amount

A hydrostatic/hydrodynamic fluid bearing assembly for a can bodymaker is provided. The hydrostatic/hydrodynamic fluid bearing assembly is separate from the ram body. The outboard guide bearing assembly includes a carriage assembly and a number of elongated journals. The carriage assembly includes a ram coupling, a crank coupling, and body defining a number of journal passages. The ram body is coupled to a ram coupling. The crank coupling is structured to be coupled to a crank arm. Each journal extends through a carriage assembly body journal passage. In this configuration, the ram body may form a can body in a traditional manner, but fluid bearing assembly fluid is not applied to the ram body. Instead, the fluid bearing assembly fluid is applied to the journals.
