A method of making a brake pad retention plate and a brake pad retention plate is provided. The method includes upsetting a brake pad facing surface on the retention plate to form a first set of rows having a gutter, or a negative feature such as a depression in the primary plane, in the surface of the retention plate and a tooth feature on a first side of the gutter. The surface of the retention plate is upset to form a second set of rows having a gutter and a tooth feature on the second side of the gutter. The second set of rows being a single row. The second set of rows is placed adjacent to or between the first set of rows. A mechanical press is used to deform the tooth to form a base portion and a mezzanine portion extending over a portion of the gutter.

A pillar for a vehicle including at least two different localized areas of different tensile strengths. The pillar includes a body defining a width that merges into sidewalls at a transition. The body having a first tensile strength and the transition has a second tensile strength, wherein the first tensile strength is smaller than the second tensile strength. The variety in tensile strength resulting from at least one of varying the material treatment and varying the gauge. The pillar is press-hardened until it reaches a tensile strength of 1500 MPa to 2000 Mpa.

A hot press processing apparatus 1 includes: a heating step of heating a workpiece W; a pressing step of press-molding, by an upper die 11 and a lower die 12, the workpiece W heated in the heating step after loading the workpiece W between the upper die 11 and the lower die 12; and a cooling step of bringing the coolant into contact with a front surface of the workpiece W that is molded and placed in a pressed state by the pressing step, to thereby cool the workpiece W and place the workpiece W in a quenched state. In the hot press processing apparatus 1, the workpiece W molded and placed in the pressed state by the pressing step forms gaps c2 with respect to both of the upper die 11 and the lower die 12 so as to allow deformation at time of the cooling step except for an accuracy-guaranteed section Wr in the workpiece W.

A manufacturing method of a press forming product, includes: constraining a first face of an intermediate formed product, the intermediate formed product including the first face, a raised face, and a first ridgeline located between the first face and the raised face, and performing flange forming of press forming the raised face into a second face, a flange, and a second ridgeline located between the second face and the flange, wherein: the first ridgeline extends while being convexly curved in a direction from the raised face toward the first face, and the second ridgeline extends while being convexly curved in a direction from the flange toward the second face, viewed from a press direction of the press forming; a convex direction of the first ridgeline in a cross section along the press direction intersecting with the first ridgeline and a convex direction of the second ridgeline in a cross section along the press direction intersecting with the second ridgeline are on the same side; a curvature radius, on a straight line orthogonal to the second ridgeline, in an extending direction of the first ridgeline at an intersection with the straight line in the intermediate formed product is larger than a curvature radius in an extending direction of the second ridgeline on the straight line after the flange forming step; and an angle formed by the second face at a position corresponding to the first ridgeline after the flange forming step is larger than an angle formed by the raised face and the first face which are adjacent to the first ridgeline in the intermediate formed product.

A method for producing a press-mold-hardened part includes providing a steel strip having an aluminium-based coating; applying an inorganic, iron-containing conversion layer to the aluminium-based coating with a layer weight in relation to iron of 3-30 mg/m2; cold-rolling the steel strip to form a flexibly rolled strip with strip sections of different sheet thickness; cutting an initial sheet metal blank out of the flexibly rolled strip, with the blank having different sheet thicknesses with thinnest and thickest sheet sections; press-mold-hardening the initial sheet metal blank to form a part. Alternatively, the cold-rolling can take place before the cutting, and the application of the conversion layer can take place before or after the cutting, or, instead of the cold-rolling, at least two steel strip sections having an aluminium-based coating and different sheet thicknesses can be welded together, where the application of the conversion layer can take place before or after welding.

An upper die of a forming apparatus includes a first curved portion and a second curved portion between a second concave section and an upper holding surface. The first curved portion is curved in a direction away from the upper die. The second curved portion is curved toward the upper die. A blank holding surface of a blank holder holds a blank between the blank holding surface and the upper holding surface of the upper die. The blank holding surface faces the second curved portion. The blank holding surface includes a blank curved surface recessed along the second curved portion.
