摘要:
Described herein is a first method of forming a hole (60) in a workpiece (100), having a first surface (110) and a second surface (112) opposite the first surface (110). The method includes forming a first hole (120), having a first diameter (D 1 ), in the workpiece (100) by passing a first cutter (116) through the workpiece (100) from the first surface (110) to the second surface (112). Additionally, the method includes forming a chamfer (142) in the second surface (112) of the workpiece (100) concentric with the first hole (120) using a second cutter (130). The chamfer (132) has a second diameter (D 2 ) larger than the first diameter (D 1 ). The method further includes forming a second hole (160), having a fourth diameter (D 4 ) larger than the first diameter (D 1 ), in the workpiece (100) concentric with the first hole (120) by passing a third cutter (150) through the workpiece (120) from the first surface (110) to the second surface (112).

摘要:
A downhole communication system has a plurality of repeaters adapted to store segments of logging-while-tripping (LWT) data during tripping. The LWT data are transmitted to the repeaters during tripping and then read out from the repeaters at the surface. The segments and repeaters are read using one or more surface communication devices, such as a rack board, a stand verifier, a box cap, or a pin cap, each adapted to access and test segments of wired drill pipe each having one or more repeaters. The rack board includes an array of communication couplers that are each adapted to exchange signals with a pin coupler of a pipe segment. In turn, each communication coupler is connected with communication equipment adapted to process and display data stored in the one or more repeaters of the pipe segments during tripping. The stand verifier includes a communication coupler and is connected to communication equipment adapted to (1) verify the functionality of communication circuitry of the pipe segment before run-in and/or after trip-out, and/or (2) download after trip-out logging-while-tripping data stored in the one or more repeaters of the pipe segment during tripping, and/or (3) download parameters stored in the one or more repeaters of the pipe segment.

According to one embodiment, a drilling machine includes at least one drilling structure, a travelling machine, a reader and a controlling device such as a controlling circuit. The at least one drilling structure drills an object to be drilled. The travelling machine positions the at least one drilling structure in a travelling direction of the travelling machine by travelling in a direction different from a drilling direction. The reader reads information recorded on at least one integrated circuit tag attached to at least one drilling plate attached to the object to be drilled. The controlling device controls the travelling machine based on the information read by the reader.

Dispositif de perçage (1) pour le perçage d'une plaque, comportant une platine porte-outils (2) munie d'une pluralité de broches de perçage (3a-3d) rotatives à forets (4a-4d) orientées selon des directions de perçage (A-A - D-D) parallèles à une direction moyenne de perçage (M-M). Des moyens (5a-5d) permettent de déplacer individuellement par rapport à la platine porte-outils (2) chacune des broches de perçage (3a-3d) rotatives selon leur direction de perçage (A-A - D-D) respective.
摘要:
A drilling method of machining holes that are not regularly arranged in one direction in a short machining time is provided. The drilling method includes: creating a machining order of machining a first hole to be machined with a first spindle (28) and a second hole to be machined with a second spindle (39) for a workpiece (38) having a plurality of target holes on a machining table (37), the first spindle and the second spindle arranged in X direction; rotating the machining table relative to the first spindle and the second spindle so that the first hole and the second hole are arranged in X direction with the first hole located nearer to the first spindle; moving the first spindle and the second spindle relative to the machining table so that the first hole and a center of the first spindle are aligned and the second hole and a center of the second spindle are aligned; and machining the first hole with the first spindle and the second hole with the second spindle.
摘要:
A plant for drilling long products ( P ) in structural steel of a quadrangular section tubular type comprising an entry ( E ) and an outlet ( U ) for the long product ( P ), a working plane ( π ) defining a first axis ( X ) in order to support the long product ( P ), locking means ( 10 ) to lock the latter on the working plane ( π ) and a supporting structure ( 20 ) overlying the working plane ( π ). The supporting structure ( 20 ) comprising three drilling heads ( 31, 32, 33 ) located above and laterally to the working plane ( π ) to drill the upper and lateral faces of the product ( P ) and control means ( 41 ) for each drilling head ( 31, 32, 33 ). The plant further comprising a working chamber ( 50 ) positioned underneath the working plane ( π ), a fourth drilling head ( 34 ) located in the working chamber ( 50 ), conveying means ( 51 ) of the shavings formed during the drilling of the long product ( P ) by the first, second and third drilling heads ( 31, 32, 33 ), control means ( 42 ) for the fourth drilling head ( 34 ) and a collecting chamber ( 53 ) for collecting the shavings coming from the conveying means ( 51 ). The plant is further characterized in the working plane ( π ) comprising at least one opening ( A ) of sufficient size to allow the passage of said fourth drilling head ( 34 ) in order to drill the lower face of the long product ( P ).
摘要:
A hole drilling device and method include a drilling head (61), a plurality of hole drilling tools (63) detachably attached to the drilling head (61), a driving device (64) for allowing the drilling head (61) to move in the radial direction and axial direction of attachment holes (60) to be formed on a tube sheet (45), and a control device (65) for driving the driving device (64). The hole drilling tools (63) are disposed, in relation to the drilling head (61), along the arrangement direction of the attachment holes (60) and at an equal interval from one another, said interval being an integer multiple equal to or greater than double the pitch of the attachment holes (60); and the control device (65) drives the driving device (64) such that holes are drilled by means of the hole drilling tools (63) as the drilling head (61) moves with respect to each pitch of the attachment holes (60) in the arrangement direction of the hole drilling tools (63). As a consequence, it is possible to simultaneously drill a plurality of holes at once and to improve the performance of the drilling operation.
