摘要:
The invention relates to a device for supporting sheet-like materials for at least one separating process in the sheet-like materials, with at least one jet cutter device which may be displaced in the Y-direction during a separation process, with a first and second support surface together forming a support table for supporting the sheet-like material and with a jet trapping device, arranged between the first and second support surfaces and provided to be able to be displaced in the X-direction. The first and the second support surfaces are made from a flexible material forming part of at least one enclosed chamber, filled with a gas under pressure.

An integrated sealing device of a laser machining head for sealing between a hollow cage member and a conduit of the laser machining head is described. The hollow cage member includes a first contact surface and a first opening therethrough. The first contact surface includes a substantially planar portion and an elastically deformable sealing lip extending therefrom. The conduit includes a second contact surface and a second opening therethrough. The sealing lip of the first contact surface is configured to contact the second contact surface to form a seal between the hollow cage member and the conduit.

A laser processing machine head, a laser processing machine head monitoring system, and a method of monitoring an optical element of a laser processing machine feature a light-transmissive optical element and an optical element holder defining a cavity in which the optical element is retained against rotation. A light source mounted to the holder directs a beam of light into the optical element through a peripheral surface of the optical element. A light receiver is responsive to light from the light source reflected through the optical element. Monitoring a signal from the light receiver allows a status of the optical element to be assessed.
摘要:
Determination of the relative positioning of a laser machining beam and a process gas jet on a laser machine tool are accomplished by motion of detections made while moving the machining beam and gas jet in relation to a detection element. In some cases actions of the beam and gas jet themselves are detected, such as by cutting light response and sensor deflection caused by the gas jet. Relative head positions at the time of the deflections are used to calculate misalignment between the laser beam and gas jet.

There is provided a machine for processing workpieces. In one embodiment, there is provided a workpiece processing machine including a processing tool movable to engage a workpiece with a force applied along a tool drive axis, a spindle member coupled to the processing tool and having two helical spindle drive threads spaced apart along the tool drive axis, through which drive threads tool forces are transmitted, and one or more drive motors operable to move the spindle member by applying force through the spindle drive threads to displace the spindle member and the tool along the tool drive axis, wherein the processing tool is coupled to the force transmission member to transmit force from the tool to the spindle member by a force transfer element coupled to the spindle member so as to distribute the force between both of the spindle drive threads.

A mechanical bending device (8) for bending flat workpieces (6) has at least one bending tool assembly (9) which includes at least one tool part that can move by means of a bending tool drive (27). When acted on by the tool part that moves, the workpiece can be bent along a bending line (11). The movable tool part is comprised of a multiplicity of adjacent segments disposed in the direction of the bending line (11), which segments can be selectively connected to the bending tool drive (27) to provide the desired operational length for the bending tool assembly. The machine tool incorporating the mechanical bending device can also include a mechanical cutting device so that workpiece parts can be both bent and machine cut in the same machine tool.

In a sleeve for a gas nozzle, a sleeve main body and a sleeve end face is formed at least in part by a wear protection element which is fastened to the sleeve main body and which is composed of a more wear-resistant material than the sleeve main body adjoining the sleeve end face, an inner and/or an outer beveled portion of the sleeve end face are formed at least in part by the wear protection element.
摘要:
A method performed by a laser machine includes: before a laser-beam machining process, recording an influence of a change in a position of at least one movable laser machine component on a lateral position of a focal point of a laser beam in a focal plane or relative to a reference point, storing an association between the position of the movable laser machine component and the lateral position, and then, setting, based on the stored association, the focal point to a preset lateral position in the focal plane or relative to the reference point by setting the position of the movable laser machine component. The movable laser machine component can include at least one of at least one optical element in a beam path of the laser beam, a laser-beam machining head in a work area of a laser machine, or a movable part of the laser-beam machining head.
