Definitions
- the invention relates to a method for bending workpieces, in particular of pipes, wires, bar materials, semi-finished products, sheets od. Like. With at least one bending device.
- the workpiece to be deformed is fed to a bending head of a bending machine by means of a feed device, for example by means of a cross slide.
- a feed device for example by means of a cross slide.
- the workpiece is picked up by means of a clamping device, for example a collet, and fed to the bending head by means of the cross slide.
- a clamping device for example a collet
- the workpieces must be bent or reshaped in a bending machine. If other bending and forming processes are required, the workpiece is fed to a further bending device for further processing. There is no exact final check of the bending state in the process.
- the present invention has for its object to provide a method for bending workpieces, in particular of pipes, wires, rod materials, semi-finished od. Like., Which eliminates the disadvantages mentioned and with which time and cost reshaped workpieces in one operation or bent If necessary, a final inspection is carried out immediately after bending.
- At least one robot receives the workpiece to be deformed and supplies at least one bending device for deforming, in particular for bending.
- a workpiece receive and supply this a bending unit consisting of at least one bending device.
- the workpiece is then deformed or bent under permanent or batch feed by means of the robot.
- the workpiece is picked up directly by the robot or a gripper arm of a robot and fed directly to a bending head of the bending device.
- the robot can rotate the workpiece with the corresponding gripper arm radially, should this be necessary.
- a conventional tensioning device or a conventional tensioning feed device can thereby be dispensed with.
- the workpiece After bending a certain area, the workpiece can be picked up by means of the robot or its gripping arm, in order, for example, to directly clamp it back into the bending device or its bending head in order, for example, to machine another end of a workpiece. This is not possible by the conventional bending process.
- the workpiece is removed by means of the robot from a storage container and fed to the bending unit or the at least one bending device for deforming or bending.
- the bent workpiece can be fed to a tray.
- the robot then grips a new workpiece to be deformed or bent from the storage container and feeds it back to the at least one bending device in a permanent or intermittent manner.
- the robot arm in particular its gripping device take over a permanent feeding and radial rotation of the workpiece during the bending process in the bending unit.
- bending devices roll bending heads, right / left bending heads, and bending device with mandrel devices, Abkante od.
- a bending unit which are arranged stationary relative to a substrate.
- the bending device can be moved relative to a substrate and in particular to the robot.
- the at least one bending device can be moved back and forth relative to the robot on a cross slide, a rail system, a linear system or the like manually and / or automatically controllable.
- a storage container can not serve a conveyor belt, a receptacle, a machine, such as a cutting machine or a transfer robot, which transfers the workpiece for forming the robot or makes available.
- the robot then transfers the finished workpiece to a tray, which may be a conveyor belt, a storage container, a machine for further processing or a transfer robot, around the finished workpiece Processing.
- a tray which may be a conveyor belt, a storage container, a machine for further processing or a transfer robot, around the finished workpiece Processing.
- the invention is not limited thereto.
- the robot may feed the workpiece to a measuring device or guide the finished workpiece along the measuring device so that the complete contour of the finished workpiece is recorded in three planes as an actual value and backed up Target value is compared. This automatically results in a final inspection after bending and forming the workpiece. If the workpiece does not correspond to the setpoint value or its tolerance range, subsequent bending can take place, in which the robot feeds the workpiece again to bend the bending unit. Only after renewed positive control in the measuring device then the workpiece of the tray for further processing or processing is transferred.
- a workpiece can be fully automatically integrated into a manufacturing process taken from a storage container, in the bending unit or the at least one bending device can be deformed or bent and then possibly after that Intermediate control of a tray can be supplied.
- Intermediate control of a tray can be supplied.
- Figure 1 is a schematic plan view of a system for bending workpieces
- Figure 2 is a schematic view of the system according to Figure 1 as a further embodiment.
- an installation Ri according to the invention for bending any desired workpieces 1 has a storage container 2 in which a plurality of workpieces 1 are mounted.
- Under the storage container 2 may also be a conveyor belt, which, for example, a plurality of workpieces, which may have been preprocessed understood.
- the storage container 2 can also be a robot or the like.
- a conveying device which provides the workpieces 1 of the installation Ri to be deformed or bent.
- the system R x is assigned at least one robot 3.
- the robot 3 has a robot arm 4, which is subdivided into several sections, with an end-side gripping device 5. With the gripping device 5, the robot 3 grasps the workpiece 1 to be deformed or bent and, after removal from the storage container 2, supplies it to the at least one bending device 6.
- a bending unit 7 more bending device 6 different types, depending on the requirement of the workpiece to be bent.
- the individual bending devices may be designed as, for example, roll bending heads, right-handed and / or left-bending heads, folding devices or the like, in order to deform a workpiece in different ways. It is important that the supply in the indicated X direction and the rotation of the workpiece 1 about the workpiece axis in the double arrowed direction Y by means of the robot 3, in particular the robot arm 4 and its end side arranged gripping device 5 takes place.
- the workpiece 1 is fed by means of the robot 3 to the at least one bending device 6 of the bending unit 7, bent there, and, after bending, is fed further in the X direction for a renewed bending of the at least one bending device 6.
- the robot takes over only the feed function in the illustrated X-direction and the radial rotation of the workpiece 1 in the illustrated Y direction. In this way, a workpiece 1 can be deformed in three planes, in particular bent.
- the robot 3 or its gripping device 5 can resume the workpiece 1 at another position in order to continue the bending process as described above.
- the finished workpiece 1 is fed by means of the robot 3 a tray 8 and stored there.
- a tray 8 As a shelf 8, a conveyor belt, a takeover robot, storage container od. Like. Serve.
- the invention is not limited thereto.
- a system R 2 is described, which is approximately the system R x corresponds. It is different here that between the bending unit 7 and the tray 8, a measuring device 9 is interposed.
- the finished bent or deformed workpiece 1 is removed from the bending unit 7 by means of the robot 3 after deformation or after bending and guided along the measuring device 9, wherein the curved contour of the workpiece 1 is moved via the measuring device 9.
- a desired state of the bent workpiece 1 is determined and compared with a stored actual value and / or tolerance field. If the actual value deviates inappropriately from the target value, the workpiece 1 can be returned to the bending unit 7 for subsequent bending and correction bending by means of the robot 3.
- a further control of the bent or deformed workpiece 1 in the measuring device 9 is carried out only after agreement of target value to the actual value, the deformed or bent workpiece 1 of the tray 8 is then supplied or passed to this.
