A ram drive assembly for a can bodymaker includes a mounting assembly and a number of forming assemblies supported thereon, each including: a stationary assembly, having a die pack and a domer, and a moving assembly having a ram assembly and a cam follower assembly. The die pack defines a passage having a proximal and a distal end, with the domer disposed adjacent the distal end. The ram assembly includes a ram body having a proximal and a distal end, with the cam follower assembly coupled to the proximal end. The ram body is structured to reciprocate through the passage between a retracted and an extended position. The ram drive assembly includes: a cam having a body with a number of surfaces for engaging each cam follower assembly; and a motor having a rotating output shaft operatively coupled to the cam body for rotating the cam body.

This application discloses aluminum alloy products, such as can body stock and can end stock, that have improved processing qualities in high-speed production equipment due to engineered surfaces. For can body stock, processing is improved by providing at least two different surface roughnesses. For can end stock, processing is improved by reducing anisotropy at least at the top and bottom surfaces of the can end stock.

A new method of manufacturing a torque-transmitting component is provided. The method includes providing a flat blank to a transfer press having a plurality of stations and performing a plurality of pressing operations, in which the flat blank is formed into a cup shape, rough splines are formed on the cup shape, and the rough splines are further pressed to define smooth splines. The component includes a continuous smooth inner diameter defined by a punch of the transfer press and a plurality of smooth splines defined by a die of the transfer press. The minor diameter of the splines is not machined to form the splines.

A can body take-away assembly for a can bodymaker with a vertically oriented reciprocating, elongated ram assembly and a domer is provided. The take-away assembly includes a drive assembly and a can body transport assembly. The drive assembly includes a motor and a support member. The take-away assembly motor is operatively coupled to said support member and structured to move said drive assembly support member in a generally horizontal direction The can body transport assembly includes a number of gripping assemblies. Each gripping assembly is coupled to said drive assembly support member. Each gripping assembly includes a number of pairs of opposed gripping members sized to grip a can body. The gripping assemblies are structured to travel across the path of said ram assembly and to selectively grip a can body.

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.

A method for manufacturing a pipe includes: press-forming a plate member into a U shape; and press-forming the plate member formed into the U shape into an O shape. The pipe includes a pipe body and a tapered part tilted radially inward and protruding from one end of the pipe body. Before the plate member is press-formed into the U shape, a boundary between a portion of the plate member corresponding to the pipe body and a portion of the plate member corresponding to the tapered part is pressed from a surface of the plate member corresponding to an inner peripheral surface of the pipe to bend the portion of the plate member corresponding to the tapered part toward the surface of the plate member corresponding to the inner peripheral surface of the pipe.
