摘要： The invention relates to a suction device (12) comprising a valve housing (18), a flexible partition wall (28) which runs in such a way that a control space (30) extends on one side and an intake side (21) lies on the other side, wherein the control space (30) is connected to the intake side (21) via a throttle passage (38), wherein the throttle passage (38) is formed in such a way that a flow resistance for flows is defined by the throttle passage (38) in such a way that, in the case of free suction, a negative pressure in relation to the intake side occurs in the control space (30) on account of the flow resistance. A sealing protrusion (44) protruding into the interior of the control space (30) and an associated seal seat (50) within the control space (30) are provided, wherein the sealing protrusion (44) and seal seat (50) are formed in such a way that, when the sealing protrusion (44) is placed against the seal seat (50), the flow path (40) through the throttle passage (38) into the control space (30) is interrupted within the control space (30).

摘要： Devices for laser welding using welding wire have a welding head, a wire guide for the welding wire, and a wire feed drive. The welding wire can be moved by the wire feed drive during a welding process with a feed movement in a feed direction, guided by the wire guide. A positioning device has a positioning drive, by which the welding wire is moved in an oscillating manner in the longitudinal direction of the welding wire, when a wire end of the welding wire is arranged in a welding readiness position. Methods for laser welding using a welding wire as added material are carried out using the devices. A control program controls the devices. The devices for laser welding can be provided as a part of a welding robot.

摘要： A planar workpiece machining device has an upper tool and a lower tool that are movable toward each other in a reciprocation direction and in the opposite direction to machine a workpiece arranged therebetween. The upper tool has a clamping shaft, an upper main body, and a tool body arranged opposite the clamping shaft on the main body and having an upper bending edge. The lower tool has a lower main body, on which a counter tool body having a lower bending edge and a counter holder are provided. The lower bending edge is oriented facing the counter holder. The upper bending edge is stationary to the upper main body, and the lower bending edge is stationary to the lower main body. The upper bending edge is associated with an undercut on the tool body and the lower bending edge is associated with an undercut on the counter tool body.

摘要： The invention relates to devices and methods for monitoring or regulating a cutting process on a workpiece. A focusing element focuses a high-energy beam onto the workpiece. An image capture apparatus captures a region at the workpiece to be monitored. The region includes an interaction region of the high-energy beam with the workpiece. An control apparatus determines at least one characteristic variable of the cutting process, in particular of a kerf formed during the cutting process, on the basis of the captured interaction region.

摘要： A method for cutting a workpiece includes cutting the workpiece along a predefined cutting contour to separate a workpiece part from a scrap part, and checking whether the workpiece part has been fully separated from the scrap part during the cutting. The workpiece is re-cut along an additional cutting contour laterally offset from the predefined cutting contour if it is found during the checking that the workpiece part has not been fully separated from the scrap part. The disclosure also relates to an associated machine for cutting a workpiece.

摘要： A method for recognition and compensation of an offset measure between stamping coordinates of a stamping device and laser coordinates of a laser device in a combined stamping-laser machine for processing a plate-shaped workpiece, particularly a metal sheet, includes introducing a structure into the plate-shaped workpiece by respectively using the stamping device or the laser device. A measurement variable of the introduced structure is determined respectively by the laser device or the stamping device. The measurement variable is compared with an expected variable, and a deviation of the measurement variable from the expected variable corresponds to an offset measure. The offset measure is balanced with the coordinates of the laser device in the laser coordinate system or with the coordinates of the stamping device in the stamping coordinate system in order to compensate for the offset measure between the stamping coordinates and the laser coordinates.

摘要： Methods, devices, and systems for production controls of process sequences in industrial processing of workpieces supported by indoor localization are provided. In one aspect, an indoor location system includes a plurality of mobile transceivers and an analyzer. At least one mobile transceiver is configured to determine a position of a selected mobile transceiver in a three-dimensional space. Each mobile transceiver is spatially assignable to a corresponding object from a group of objects within a framework of process sequences. Each object is movable in one or more dimensions in the three-dimensional space. The analyzer is configured to determine the position of the selected mobile transceiver based at least on run times of electromagnetic signals between the mobile transceivers in a position determination process and to perform tracking of a movement of a target object assigned to the selected mobile transceiver based on the position of the selected mobile transceiver.

摘要： A method for evaluating a laser cut edge of a workpiece includes capturing image data of the laser cut edge and its surroundings, segmenting the image data, and identifying a segment of interest of the image data. The segment of interest comprises image data of the laser cut edge. The method further includes carrying out an image quality detection for the segment of interest and generating, based on the image quality detection, an output for a user.
