Embodiments include a clamping apparatus comprising a pair of adjustable anvils configured to apply a clamping pressure on a workpiece secured between the anvils; a center gear comprising a pair of anvil holders respectively coupled to the pair of anvils; an open center configured to receive the workpiece, the anvils being positioned within said open center; and a pair of outer gears arranged on either side of the center gear, the outer gears being configured to rotate about the open center. Rotation of the outer gears causes a linear movement of the anvils along an axis perpendicular to workpiece. Embodiments also includes a clamping system comprising the clamping apparatus, as well as a positioning device for driving the center gear based on a positioning input and a clamping device for driving the outer gears based on a clamping input.

A tie bar tensioning system that allows a bending machine operator to removably couple an upper end of a bend die post of the bending machine to a base of the bending machine via a tie bar, and to lock the tie bar in a tensioned position. The tensioning system includes a stationary member and a rotatable member, each with aligned tie bar passages for receiving the one end of the tie bar. Both the stationary member and the rotatable member include respective engagement surfaces, with the rotatable member engagement surface being rotatable relative to the stationary member engagement surface between a released position and a tensioned position whereat the rotatable member is selectively lockable. The rotation of the rotatable member with the stationary engagement surface in engagement with the stationary engagement surface longitudinally displacing the rotatable member relative to the stationary member.

A conduit bender having a unitary frame is mounted to a wheeled base which provides for transportation of the bender. A braking assembly provides for simplified locking of the wheels to secure the bender in a location. The bender is mounted to the base through a pivoting assembly which allows for bending of conduit in either a horizontal or vertical plane. A circuit is provided for controlling the bending operation. An auto-sensing portion of the circuit receives information regarding the characteristics of the conduit to be bent upon placement of the conduit in the bender. A feed back portion of the circuit is used to provide a precise bending operation.

A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.

A manufacturing method for a bent product which can guarantee a high working accuracy and which can provide a large bending angle without damage to the surface condition of a metal material even when a widely varying bent shape is desired or when it is necessary to perform bending of a high strength metal material.A bent product having a three-dimensionally bent portion intermittently or continuously in the lengthwise direction is manufactured by supporting a steel pipe 1 at a first position A while feeding it in the lengthwise direction, locally heating the steel pipe 1 being fed at a second position B, cooling the heated portion of the steel pipe 1 at a third position C, and varying the position of a gripping means 15, which grips the steel pipe 1 in a region D downstream of the third position C, in a three-dimensional direction including the feed direction of the steel pipe 1 in a workspace including a space on the upstream side of the third position C in the feed direction of the steel pipe 1 to impart a bending moment to the heated portion of the is steel pipe 1.

A method and apparatus for three-dimensionally bending a metal material are provided. A product intermittently having a bent portion which curves three-dimensionally and a quenched portion is manufactured by a bending method which performs bending downstream of a support means while feeding a metal material which is supported by the support means from an upstream side towards a downstream side. A portion of the metal material is heated by a heating means for the metal material downstream of the support means, a bending moment is imparted to the portion of the metal material which was heated by the heating means to carry out bending by three-dimensionally changing the position of a movable roller die which is disposed downstream of the heating means and has a plurality of rolls which feed the metal material which was heated by the heating means in the axial direction, and the metal material is quenched by spraying a cooling medium at the portion of the metal material which was heated by the heating means by a cooling means disposed between the heating means and the movable roller die. Errors in a product due to bending are suppressed by supporting a portion of the metal material which has exited from the movable roller die.
摘要:
The present invention relates to a method and apparatus (1, 31) for forming a three-dimensional object and in particular to a method and apparatus (1, 31) for forming a three-dimensional beam (5). It is desirable to form three-dimensional beams (5) having complex forms by using an efficient forming process for the beams which may be incorporated into existing high volume production techniques. The apparatus (1, 31) for forming three-dimensional beams (5) comprises a support means and an actuation means. Support members (2, 32, 41, 51, 61) spaced about the longitudinal axis of the support means locally define an opening (4, 35, 43, 53, 63) for supporting a section of the beam (5). The position of adjacent openings (4, 35, 43, 53, 63) relative to one another defines the overall form of the beam (5) and the actuation means defines the position of each opening (4, 35, 43, 53, 63).
摘要:
A bending machine comprises a plurality of bending units arranged to make bends in a common plane. The bending units are adjustably mounted to adjust the separation thereof in the common plane. Apparatus for holding and turning a workpiece about a predetermined axis is mounted between the bending units so that the predetermined axis is aligned or alignable with the common plane. The apparatus comprises a plurality of jaw members rotatable in unison about the predetermined axis. Each jaw member is axially open ended, has a central socket and a mouth extending from said socket to interrupt the periphery of the jaw member. The jaw members are interconnected and mounted to rotate in unison about the predetermined axis when at least one thereof is driven by a driving mechanism. A clamping jaw member is arcuately movable relative to the other or others between an open position, in which the mouths are aligned to admit a workpiece into the sockets, and a clamping position, in which the mouths are not aligned to trap the workpiece in the sockets. In the clamping position, the socket of the clamping jaw member is eccentric to the other or others of the sockets to exert a clamping force on the trapped workpiece.

For grasping and rotating a tube having a flared end and a rotatable flare fitting thereon a chuck carries a number of pivoted clamps movable radially inwardly against the fitting. An opposing pilot on the chuck enters the end of the tube to axially bear against the inside of the flared end, thereby clamping the rotatable fitting against the tube between the clamps and pilot for a firm grip on the tube end. The clamps and pilot are driven into opposing gripping relation by a slidable chuck housing sleeve which, in turn, is axially driven by a non-rotating thrust block. The housing sleeve, clamps and pilot are all carried for rotation on a driven shaft.
