| 121 | High speed ball header | US699892 | 1976-06-25 | US4044588A | 1977-08-30 | Allan D. Haines |
| A ball header is disclosed in which the movable die is mounted directly on the machine frame rather than on the reciprocating slide. The position of the movable die is controlled by a cam driven pusher so that the movable die position is dependent of the position of the reciprocating slide. The machine provides a greater portion of the machine cycle for the movement of the transfer from between the dies after the blank is gripped and controlled by dies. The machine further provides a closed or bushing cutter to improve the shearing of the blanks from the wire stock so that the part formed by the machine can be closer to the finished size of the product to reduce the material content and the cost of finishing operations. The accuracy of the positioning of the movable die is also improved by the mounting of the movable die directly on the frame rather than on the reciprocating slide. | ||||||

| A method of forming an article in the form of a one-piece, hollow, elongated body having an enlarged center portion and narrowed or necked down end portions is provided. The method is shown as applied to forming a hollow roller shaft having an internal, centrally disposed lubricant cavity within a central body and a pair of shaft journals extending therefrom.

| 140 | COLD FORMING METHOD FOR PRODUCING BALL JOURNALS | PCT/DE2004002614 | 2004-11-25 | WO2005051594A3 | 2005-09-22 | KRUSE JOCHEN; ROSENBERGER KLAUS |
| The invention relates to a cold forming method for producing ball journals comprising a ball region, a conical region and a threaded region for installation in ball-and-socket joints. According to said method, a ball journal blank (1) comprising a formed conical region (3) and cylindrical regions for the thread (2) and ball (5) are produced from a rod-shaped semi-finished bar material by extrusion. After the extrusion step, the ball region is subsequently formed by means of a rolling method in an additional production stage. At the same time, the threaded region can be given its final form. The production of the ball journal is thus achieved exclusively by cold forming and permits a significant increase in the production quantity per time unit in comparison with known methods in prior art. More economical types of steel can thus be used, as the cold forming method guarantees the sufficient durability of the ball journal. | ||||||
