A method for manufacturing a formed product includes: (i) bending a plate-shaped workpiece, which extends in a length direction of the formed product and has at least one through part formed therethrough, by roll forming to form at least one ridge part on the workpiece such that the at least one ridge part overlaps the at least one through part; (ii) cutting the workpiece, which has the at least one ridge part formed thereon, along a cutting plane intersecting the length direction through the at least one through part, thereby obtaining an intermediate formed product having a main body part and at least one end piece part facing the at least one through part from a direction perpendicular to the length direction; and (iii) bending the at least one end piece part to form at least one flange part on the intermediate formed product, thereby obtaining the formed product.

The invention relates to a method for processing an intermediate form of a component for a particle beam device. For example, the particle beam device is configured as an electron beam device and / or as an ion beam device. The invention further relates to a computer program and a sealing device for carrying out the method. The method comprises adding a liquid to a liquid-soluble plastic to modify the plastic such that it becomes rubber-like and sealing, applying the plastic to a surface of the intermediate form such that the plastic adheres to the surface in a sealing manner, applying an adhesive to the intermediate form, and adding the liquid to the plastic again, so that the plastic is dissolved.

An apparatus and method for forming three-dimensional articles is provided. [Solution] The present invention is a method for forming a fibrous molded article, the method including providing an aqueous slurry containing a plurality of fibers; providing the slurry in a dewatering chamber to remove at least a portion of a quantity of water from the slurry and achieve an intermediate form; removing the fibrous intermediate form from the dewatering chamber and placing the fibrous intermediate form in a press having a first mold portion and a second mold portion, at least one of the first or second mold portions including undulations; applying at least one of heat and pressure to the press so as to cause at least interfiber bonding or chemical crosslinking of the fibers; and removing the three-dimensional solid fibrous molded part from the press.

A press forming method is through a draw forming step and a trimming forming step, and a formed product is a hat-shaped formed product including a top surface portion, an outer corner portion, a vertical wall portion, an inner corner portion, and a flange portion. In the draw forming step, an intermediate formed product (8) including a convex portion (81) corresponding to the outer corner portion and a concave portion (83) corresponding to the inner corner portion is formed. The curvature radii of the convex portion (81) and the concave portion (83) are made larger than those of the outer corner portion and the inner corner portion, and the cross-sectional shape of the convex portion (81) is made more bulged toward the top surface portion side along a press direction F than that of the outer corner portion. In the trimming forming step, by pressing a position inside the intermediate formed product (8) more than the convex portion (81) and a position outside more than the concave portion (83), material outflow from the inside to the outside and material inflow from the outside to the inside are suppressed, and at the same time, the convex portion (81) is pressed toward the concave portion (83) side along the press direction F, whereby the outer corner portion and the inner corner portion are formed.

A manufacturing method of a press formed part, the press formed part including at least a main body portion, which has a top plate portion and vertical wall portions formed via ridge portions, and an outward flange portion formed continuously with the top plate portion, the ridge portions, and the vertical wall portions at an end portion of the main body portion, the method includes: an intermediate forming step of forming an intermediate formed part having the top plate portion and the vertical wall portions formed via the ridge portions, and including a step-shaped portion bulging outward at a root portion of an outward flange corresponding portion which is to be formed into the outward flange portion; and a target shape forming step of forming the outward flange portion by bending and raising the outward flange corresponding portion of the intermediate formed part outward, and acquiring a target shape.

A method of manufacturing a formed sheet metal structure having a final formed sheet metal shape includes the steps: providing a sheet metal workpiece A; plastically deforming the workpiece to provide an intermediate formed sheet metal shape B. The intermediate shape comprises a first pattern of at least three creases C1, C3, C4, that meet at a first non-developable vertex NDV1, C, and a second pattern of at least three creases C2, C5, C6, that meet at a second non-developable vertex NDV2. Then bending the workpiece to carry out one or more of: (i) moving one or more of the creases within the workpiece; (ii) removing one or more of the creases; (iii) adding one or more further crease that meets other creases at the first and / or second non-developable vertex. In this way, the geometry of the first and / or second non-developable vertex is changed to provide the final formed sheet metal shape for the formed sheet structure. The plastic deformation may use a main anvil tool, a main forming tool, an auxiliary anvil tool, and an auxiliary forming tool (Figure 3A). The auxiliary tools may carry out shear material transfer in the workpiece to get the NDV1 and NDV2. [Figure 15]

To provide a forging molding device capable of extending the die life of a molding die.SOLUTION: A forging molding device K comprises a molding die S for performing forging molding on a material M and a punch P that pushes the material M toward the molding die S disposed on the front side in a molding direction. The molding die S molds an outer surface of the material M by a branch flow of material flow occurring in the material M during forging molding along a direction orthogonal to the molding direction, with respect to the material M having an outer dimension smaller than an outer dimension of a product W after forging molding, and includes a first molding die S1 that molds an intermediate molded body having an intermediate shape from the material M, and a second molding die S2 that molds a product W being a final molded body having a final shape whose outer dimension is smaller than the outer dimension of the intermediate shape from the intermediate molded body.SELECTED DRAWING: Figure 1
