| 072344000 | With stripping or ejecting from tool | 7 |
| 20100126243 | STRIPPER DEVICE FOR CAN DRAWING AND IRONING APPARATUS - A stripper device for can drawing and ironing apparatus can remove a drawn and ironed can material from a punch without causing buckling (curl and wrinkle) on the material. Each finger ( | 05-27-2010 |
| 20110265543 | Take-off ring - The invention relates to a take-off ring | 11-03-2011 |
| 20160144422 | SPIRAL BEVEL GEAR FORGING APPARATUS - A spiral bevel gear forging apparatus for forging a blank includes a first mold core having a mold cavity for receiving the blank, a first punch rod inserted movably into the first mold core and having a positioning end extending into the mold cavity for releasable engagement with a bottom of the blank, at least one push mechanism, and a drive mechanism. When the drive mechanism is operated to move from a non-ejecting to an ejecting position, the push mechanism is actuated to drive the first mold core to rotate about the first punch rod, and the first punch rod is actuated to move relative to the first mold core such that the positioning end thereof is moved out of the mold cavity for ejecting the blank out of the first mold core. | 05-26-2016 |
| 072345000 | Timed with tool motion | 4 |
| 20090255316 | Trim and Pierce Press Assembly and Method of Use - A press assembly including a die assembly having a trim die defining an annular cavity wherein the trim die is fixed to the press assembly, a punch assembly including a trim punch having an annular boss that is correspondingly shaped to the annular cavity, wherein the trim punch is movable relative to the die assembly, and an ejector assembly including an ejector arm, wherein the ejector arm is mounted to the punch assembly. The object is pressed into the annular cavity of the trim die by the annular boss of the trim punch when the annular boss is slidably received in the annular cavity, and the ejector arm pushes the object upwardly within the annular cavity of the trim die when the annular boss of the trim punch is removed from the annular cavity. | 10-15-2009 |
| 20100275670 | PRESS WORKING METHOD AND PRESS WORKING APPARATUS - In a press working apparatus, while a servo motor is acting, an upper die is made to come close to a lower die and press working of the first time is conducted on a steel plate. A slider is raised to a movable punch preparation position. A movable punch is protruded from a die face of the upper die by width and locked by a mechanical lock. The upper die is made to come close to the lower die again and the steel plate is pushed with the upper die and at the same time an additional worked portion is pushed and deformed with the movable punch so as to conduct press working of the second time. After the movable punch has been retracted, the slider is raised. | 11-04-2010 |
| 072346000 | With work feeding | 2 |
| 20140260494 | PIERCING APPARATUS, PLUG USED FOR PIERCING APPARATUS, AND METHOD FOR PRODUCING SEAMLESS STEEL PIPE - There is provided a piercing apparatus in which the occurrence of an inner surface flaw in a hollow shell is suppressed. A piercing apparatus ( | 09-18-2014 |
| 20140311206 | METHOD AND APPARATUS FOR TRANSLATING CAN BLANKS - A redraw press with an improved can blank transfer mechanism is provided which allows for a substantial increase in the operating speed of the press. Servomotors are used to accurately control positioning and rates of movement of the can blanks as they move downstream through the press. | 10-23-2014 |
