| A processing apparatus for processing a workpiece by transferring the workpiece between a ram and a die block. At least one recessed die of a plurality of dies molds the workpiece into a bottomed tubular shape by a punch. A punch, among a plurality of punches, that has entered the recessed die exits from the recessed die with the formed workpiece being attached to the punch, together with the workpiece. Since the workpiece is transferred from the die block to the ram when the punch exits from the die, a step of moving the ram forward relative to the die block to transfer the workpiece from the die block to the ram can be omitted accordingly. | ||||||

| There is provided a method of manufacturing a metal shell formed body by cold forging for a metal shell of a spark plug. In the manufacturing method, a semi-finished formed body is first provided with a second inner step without the formation of an annular front end portion. After the semi-finished formed body is inserted from its front end side into a die, a punch having an annular is pushed into the semi-finished formed body from its rear end side. By pushing the punch, an annular front-facing surface of the punch is pushed onto the second inner step so as to press a front end portion of the formed body against an annular front end portion forming part of the die. By such a forming step, the metal shell formed body is obtained in which the annular front end portion is formed by extrusion. | ||||||

| A metal shell of a glow plug mounted on an engine head of a diesel engine and a method of manufacturing the same are disclosed. The metal shell has an improved multi-stage structure, which allows the metal shell to be easily manufactured regardless of overall length of the metal shell and allows a metal shell section fastened to the engine head and at least one of the other metal shell sections to have different material strengths, thereby increasing fastening strength of the metal shell to the engine head and preventing warpage of the metal shell while improving productivity while reducing manufacturing costs. The metal shell of a glow plug for diesel engines according to the invention includes a plurality of metal shell sections disposed in an axial direction of the glow plug and having different material strengths. | ||||||

| 95 | Unitary connector pin formed by two-stage cold heading die | US13780331 | 2013-02-28 | US09126258B2 | 2015-09-08 | Robert Rottinghaus |
| A unitary metal connector pin formed by a cold heading die has a body with a disc-like expanded portion on a first end thereof which is adapted to engage and retain a first body when the pin is inserted through a first aperture in the first body. On a second, opposed end of the pin are disposed plural spaced flexible fingers each having a respective outwardly projecting, radially expanded portion. The radially expanded portions form a segmented outer ring on the pin capable of first undergoing inward deflection, followed by outward radial expansion for engaging a second body when the fingered end of the pin is inserted through a second aperture in the second body for securely coupling the two bodies together. The cold heading die includes a first stage for forming in a connector pin blank a first hollowed-out end portion with the flexible fingers and a second stage for forming the second radially expanded end portion and the outer projections on the flexible fingers. | ||||||
