A method for fabricating a segmented electrode is provided. The method includes performing a series of progressive die stamping operations on a foil sheet of material to form an initial electrode, and removing portions of the initial electrode using a centerless grinding process to form a segmented electrode including a plurality of circumferentially spaced contacts.

An element manufacturing method for a transmission belt of a continuously variable transmission having a thick wall portion and a thin wall portion formed by sequentially feeding a material having a strip shape with a uniform thickness to each press position and performing press working on the material at the press position. The method includes, as the press working performed at the press position: a preliminary punching step in which a portion other than a connecting portion is cut off from surrounding material and the cut off portion is punched so as not to overlap with the surrounding material in a plate thickness direction; a crushing step of compressing and crushing a region of the thin walled cut off portion, after the preliminary punching step; and a punching step of punching the cutting off portion into an outer shape corresponding to the element, after the crushing step.

A method for manufacturing a beam (P1, P2) with closed section, the beam being produced by combining a first profile (P10, P20) and a second profile (P11, P21), including the following steps: producing the first profile by a first stamping of a first plate (5, 50) between a first punch (1, 10) having a first imprint and a second punch (2, 20) having a second imprint and incorporating a core (3, 30) modifying its second imprint; holding the first profile (P10, P20) on the first punch and positioning the core (3, 30) above the first profile (P10, P20); producing the second profile (P11, P21) by a second stamping of a second plate (6, 60) against the core (3, 30) between the first punch (2, 20) and the assembly formed by the superposition of the first punch (1, 10), the first profile (P10, P20) and the core.

An automatic production equipment includes a strip-material feeding device set, a continual stamping die set and a rivet providing mechanism. The strip-material feeding device set feeds a strip material. The continual stamping die set includes a upper stamping die group and a lower stamping die group. The lower stamping die group includes a lower die plate, a strip receiving groove formed on the lower die plate for receiving the strip material, a sliding block slidable on the strip receiving groove, and a guide groove formed on the sliding block to connect to the strip receiving groove. The upper stamping die group includes an upper clamping plate, a pushing lever and a riveting punch. The pushing lever and the riveting punch are located on the upper clamping plate. The rivet providing mechanism is connected to the sliding block, and feeds rivets into the guide groove in order.

The invention relates to a transfer press for successive forming and demoulding of work pieces by means of upper and lower tools in dies, wherein the upper tools are attached to a ram head, while the lower tools are installed on a ram foot. The ram head and the ram base are rigidly connected to each other and form a ram.

Presented are metalworking systems for forming metallic workpieces, methods for making/operating such metalworking systems, and battery module cell tabs bent by a multistage cluster-and-bend press. A metalworking system includes a grouping tool and a contouring tool that both align adjacent a workpiece support structure, such as a base plate of a battery module housing buttressing a stack of battery pouch cells. The grouping tool, which may include a first reciprocating plunger or plunger head, presses together a stack of metallic workpieces to thereby form a workpiece set having a first bend profile and a first length. The contouring tool, which may include a second reciprocating plunger or a pair of plunger fingers mounted on the plunger head, is attached to the grouping tool and bends the workpiece set to a second bend profile, distinct from the first bend profile, and a second set length, shorter than the first set length.

Examples of methods of hot forming structural components are provided. The methods include heating a blank made from an Ultra High Strength Steel with an aluminum coating and forming the heated blank in a multi-step apparatus.
