摘要： An incremental forming tool of the present invention includes a holding portion attached to an incremental forming apparatus and a free curved surface part for pressing a metal plate.
The free curved surface part is made of at least a hard metal base material and a surface of the free curved surface part is covered with a hard film.
The surface of the hard film has an Rpk of 0.15 μm or less, the Rpk is defined by JIS B 0671 and is calculated from a material ratio curve of a roughness curve, and has an Ra of 0.2 μm or less, the Ra is defined by JIS B 0601 and is calculated from a roughness curve. Therefore, a molded product having a smooth worked surface with no roughness can be produced without adding any extra equipment for preventing adhesion.-

摘要： A method of producing a hot press-formed product, in which a die includes a hard layer having a skewness (Rsk), as measured in a direction from the outside of a die hole toward the inside of the die hole, of from −5.0 to 1.2, and a hardness Hv_Die of from HV 1,000 to 1,550, over the entirety of a region of a steel sheet contact surface that is adjacent to a die shoulder portion. The steel sheet contact surface is a surface located outside of the die hole and configured to contact a plated steel sheet (a plated steel sheet including at least one kind of plating layer selected from the group consisting of a hot-dip galvanizing layer and a zinc nickel plating layer) that is to be subjected to hot press forming.

摘要： The invention provides a hard coating film insusceptible to adhesion to a soft metal, the hard coating film being suitable for use as a coating on the surface of, for example, a die in contact with the soft metal. Further, the hard coating film includes a metal element containing at least two species of elements selected from the group consisting of Ti, Al, and Cr, and a non-metal element containing O (oxygen) only, or O and at least one species selected from the group consisting of C and N. A proportion accounting for the O in the total non-metal element is not less than 0.2, in atom ratio.

摘要： A shaping apparatus for shaping a workpiece. The apparatus comprises first and second pairs of shaping members and a spacer located between the first and second pairs of shaping members. The first pair of shaping members comprises a material having a first linear coefficient of thermal expansion, and the second pair of shaping members comprises a material having a third linear coefficient of thermal expansion. The first linear coefficient of thermal expansion is higher than the second linear coefficient of thermal expansion such that on heating of the apparatus, thermal expansion of the shaping members causes the first pair of shaping members to expand outwardly, and the second pair of shaping members to expand inwardly.
