470057000 | APPARATUS FOR MAKING EXTERNALLY THREADED FASTENER OR ARTICLE, E.G., SCREW, BOLT, ETC. | 6 |
20100113172 | THREADING MACHINE FOR THE CONNECTION OF DEFORMED REINFORCING BARS - A threading machine for the end threading of long metal bars includes a peeler and a threader mounted co-axially on a spindle. The spindle is powered by a motor. A leading rod is attached to the clamping chariot. The leading rod includes the peeler opening and closing controller, and the threader opening and closing controller. The controllers are supported by a carriage set, and the threader is able to travel forward and backward. The peeler opening controller and threader opening controller are adjustable by moving them along leading rod to accommodate various thread length. | 05-06-2010 |
20120165107 | FASTENER, DRIVER ENGAGING WITH THE FASTENER AND PUNCH PRODUCING THE FASTENER - A fastener includes a connecting portion and a head portion coaxially connecting with the connecting portion. The head portion defines an engaging hole which includes a main engaging hole and one or more auxiliary engaging hole coaxial with the main engaging hole. A plurality of auxiliary engaging teeth are separately formed on an inner peripheral wall of the engaging hole, toward a central axis of the engaging hole of the head portion, thereby forming the auxiliary engaging hole. A plurality of main engaging teeth are coaxially formed on the auxiliary engaging teeth, toward the central axis of the engaging hole respectively, and are positioned at the base of the engaging hole. The fastener provides two bearing surfaces on which a driver can act upon, and the present disclosure further provides the driver to engage with the fastener and a punch for producing the fastener. | 06-28-2012 |

20120100920 | BEVELLING APPARATUS FOR PRODUCING SCREWS AND THE LIKE - A beveling apparatus, for manufacturing screws and the like, includes a fixed support structure, which includes a first motor unit and a second motor unit which actuate a pliers unit adapted to lock an item to be machined and associated with a movable supporting structure. The first motor unit is constituted by a pair of linear motors having rotors associated with a carriage which actuates the pliers unit. The second motor unit has a pair of linear motors having rotors associated with the movable supporting structure so as to actuate the axial movement of the movable supporting structure with respect to the fixed supporting structure in order to define at least two operating positions of the pliers unit; a position for picking up and unloading the item to machined, in which the pliers unit is at a certain distance from a machining head of a machine tool, and a position for machining the item, in which the pliers unit is located at the machining head of a machine tool. | 04-26-2012 |
20130065698 | INSTRUMENT FOR ASSEMBLING A BONE ANCHORING DEVICE - An instrument for assembling a bone anchoring device includes a shank with a shaft section to be anchored in a bone and a engagement end, a head being separate from the shank and having a through bore, and a receiving part having a first end, a second end and a longitudinal bore extending from the first to the second end, the head being positionable within the bore at the second end. The instrument includes a holding portion arranged to hold a pin, which has a rod section with a length and a diameter suited to fit and extend at least through the bore of the head, and which has a free end portion extending from the rod section such as to project from the bore of the head when the pin is inserted, and configured to engage with the engagement end of the shank. | 03-14-2013 |
470060000 | Having head nicking | 1 |
470063000 | Punch and die type | 1 |
20090069103 | PUNCH AND RELATED RECESSED SCREW - The present invention pertains to a punch for forming recessed screw comprising a punch body and a punch head. Particularly, the punch head includes two square portions having different heights and square sides and intersecting at an included angle, thereby punching the corresponding tiers of recesses in the socket of the screw head. In this manner, the screw can be facilely driven by a screwdriver presenting a square configuration or a uniform shape as the punch, which facilitates to reduce the problem of unfitted driving tool and increase the convenience while in operation. | 03-12-2009 |
470066000 | Having thread cutting means | 1 |
470082000 | Having recessed cylindrical die block | 1 |
20160031024 | Thread Cutter Drive Extension - A thread cutter drive extension includes a main body defining first and second connecting ends. The main body includes a cavity circumferentially delimited in the second connecting end and a hole extending radially through the connecting end and into the cavity. A tightening device is disposed on the main body. The tightening device includes a tightener adjustably engaged in the hole. The tightener is movable between a tight position engaging in the cavity and a release position disengaging from the cavity. The thread cutter drive extension defines a driven end at the first connecting end. The thread cutter drive extension is adapted to be driven by a power tool, with the power tool connecting to the first connecting end. The thread cutter drive extension is adapted to receive a thread die, with the thread die disposed in the cavity. | 02-04-2016 |
