Pump actuator with stamp-aligned anti-rotation feature
A tappet, which may be a fuel pump actuator, includes a body that is a contiguous piece of case-hardened ferrous metal. The body has a cylinder-conforming bore-running surface and an anti-rotation guide feature that has been made by stamping to project outwardly from the bore-running surface. A cam follower is mounted to the body. The body has been case hardened by ferritic nitrocarburizing, but has not been distorted by heat treatment and has a malleable interior. A transverse web for the tappet may be fully hardened. Axle holes for the cam follower may be formed by stamping. The tappet is durable and provides superior alignment of the roller to a cam, which reduces friction and noise.
Process of producing a boom part as well as a boom and a boom part or boom produced therewith
The present invention relates to a process of producing a boom part from a sheet metal blank, in particular a process of producing a boom part having a bearing seat, in which the starting material is merely formed by bending. Thus, the production process is simplified. In addition, the present invention relates to a process of producing a boom that is closed at both ends by joining two boom parts produced by means of the process of the present invention. Furthermore, the present invention comprises boom parts and booms which are produced by means of one of the processes according to the present invention.
METHOD FOR MANUFACTURING CONTAINER AND APPARATUS FOR MANUFACTURING CONTAINER
A manufacturing a container makes it possible to easily manufacture a container including a body portion with a shape that expands outward toward an upper face side. A method for manufacturing a container according to the disclosure is a method for manufacturing a container made of metal, including a bottom portion and a body portion, open on the upper face side, and having a shape in which the body portion expands outward toward the upper face side. The method includes a bottom drawing step of reducing a diameter of a cup body made of metal and having a bottomed cylindrical shape by operating a diameter reducing die having a hole portion with a smaller diameter than an outer diameter of the cup body along a cylindrical axis direction from a bottom side, in which the bottom drawing step is repeated a plurality of times.

METHOD FOR MANUFACTURING SHAFT
A method for manufacturing a shaft (1) in which linking members (3) are provided to ends of a cylindrical member (2) including: polishing end surfaces of a metal sheet; a bending step for bending the metal sheet into a cylindrical or arcuate shape; butting together the polished end surfaces of the metal sheet, the end surfaces facing each other in a state in which the metal sheet has been bent into the cylindrical shape, or disposing a plurality of the metal sheets that are bent into an arcuate shape so as to form a cylindrical shape and butting together the polished end surfaces of the metal sheets, and then heating the butted portions so that the butted portions are diffusion-joined, thereby forming the cylindrical member (2); cooling the post-diffusion-joining-step cylindrical member (2); and joining the linking members (3) to the ends of the cylindrical member (2).
Pouch-Shaped Case Forming Apparatus and Method of Manufacturing Pouch-Shaped Case Using the Same

MANUFACTURING METHOD OF BATTERY CASE
A manufacturing method of a battery case having a rectangular transverse cross-section in which an intermediate product having an elliptical transverse cross-section is shaped into a final product having a rectangular transverse cross-section by drawing and ironing the intermediate product multiple times to reduce a curvature radius of each corner and thicknesses of side walls formed on both sides of the corner. A difference between an ironing rate of the side wall formed on one side of the corner and an ironing rate of the side wall formed on the other side of the corner is reduced less than a predetermined difference, after the curvature radius of the corner between the side walls has been reduced shorter than a predetermined radius during the process of shaping the intermediate product into the final product.
