A guide pin assembly includes a guide pin body that connects to a die component using retaining rings. The guide pin assembly has an upper and a lower retaining ring that permits the retention of the guide pin body in a hole in a component of a metal forming die, with each retaining ring contacting a surface of the die component. The guide pin body includes an opening to permit the temporary insertion of a device for positioning the guide pin body within the opening in the die member.

The present disclosure discloses a hot-forging die with the conformal meshy structured cavity surface layer and a preparation method thereof. A large-scale hot-forging die includes a die substrate, and a sandwiched layer, a transition layer and a reinforcement layer are formed on the die substrate in sequence. The reinforcement layer and the transition layer are separated into a plurality of small units by the grooves. All the grooves are interconnected and communicated to form a meshy structure. The transition layer grooves are filled with ordinary soft material; the reinforcement layer grooves are filled with high temperature resistant soft material. The reinforcement layer material and the high temperature resistant soft material of the present disclosure cooperate with each other to obtain a cavity surface layer with properties of both hard and soft, strong and tough, which can fully release the large tensile stress that may occur on the surface of the die cavity during the welding process and under the service conditions of the die, so as to avoid hot cracks during welding process and service process.

The present invention aims to provide an interlayer film for a laminated glass having recesses in the shape of engraved lines on both surfaces to exhibit excellent deaeration properties in production of a laminated glass and suppressing formation of a moire pattern when unwound from a rolled body thereof. The present invention also aims to provide a laminated glass including the interlayer film for a laminated glass, a method for producing an embossing roll suitably used for production of the interlayer film for a laminated glass, and a method for producing the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of recesses on both surfaces, the recesses each having a groove shape with a continuous bottom and being regularly adjacent and parallel to each other, the interlayer film having a glossiness on a surface with the large number of recesses measured in conformity with JIS Z 8741-1997 of higher than 3% or a haze value measured in conformity with JIS K 7105-1981 of 87% or lower.

A pressed component manufacturing method wherein, in press forming a metal sheet into a final component shape through two or more press steps, the inflow amount of the required material is determined based on the increase in the cross-sectional line length of the shape with respect to the line length before forming when the metal sheet is press formed by a single press step, the determined amount is distributed to each step, and a preformed shape after press forming based on the distributed inflow amount. As the cross section, a line orthogonal to a direction in which the material flows when the metal sheet is drawn is set, and a plurality of cross sections is set which is individually cut by each of planes orthogonal to the line and extending in a direction along the sheet thickness direction of the metal sheet before forming.
