Definitions
- the invention relates to a device for forming with at least one spindle which can be driven in rotation via a rotary drive, a clamping device which is arranged on the spindle and is designed for receiving and clamping a workpiece on the spindle, and at least one forming roller which is axially and / or can be advanced radially relative to the workpiece in order to carry out a pressure-forming or pressure-rolling process, according to the preamble of claim 1.
- the invention further relates to a method for forming, in which at least one spindle is driven to rotate by means of a rotary drive, a workpiece is picked up on the spindle by means of a clamping device and clamped on the spindle and at least one forming roller is axially and / or radially relative to the workpiece Performing a flow-forming or flow-forming process is delivered, according to the preamble of claim 11.
- the flow forming process is an efficient process for the production of particularly rotationally symmetrical parts in series production.
- Flow-forming processes are particularly advantageous in the manufacture of transmission parts such as belt pulleys and rollers, vehicle wheels and a large number of other products.
- a known device for forming by means of spinning rollers is from DE 10 2007 012 765 B4 known, with separate feed and discharge devices being provided.
- the U.S. 4,047,413 discloses an automatic spinning device in which a plurality of spindles, each with a workpiece, are arranged in a ring around central spinning rollers.
- the annular spindle assembly is rotated about a central axis.
- the invention is based on the object of specifying a device and a method for forming with which particularly efficient set-up is made possible.
- the device according to the invention is characterized in that the spindle and the clamping device are combined to form an interchangeable unit, which can be adjusted transversely to the axis of rotation, and that the interchangeable unit can be adjusted between a forming position of the device and a set-up position.
- a basic idea of the invention is to feed or remove a workpiece in a device for forming by moving the spindle with the clamping device out of the limited working space from the forming position into a more accessible set-up position. In this set-up position, the workpiece can be fed or removed and clamped in a simple manner. After this handling process, the spindle with the tensioning device can be moved back into the flow-forming position in which the flow-forming or flow-forming process (s) are then carried out. For this purpose, the spindle and the clamping device are combined into one unit, which can be referred to as a changeover or moving unit. Spinning is rotational forming without any significant change in wall thickness, while wall thicknesses are specifically reduced and / or increased in spinning. Forming in the sense of the invention is to be understood in general terms and also includes profiling, upsetting, ironing and the like.
- the inventive concept of moving the spindle with the clamping device into a set-up position enables a feed device to be considerably simplified. This makes it possible to considerably simplify handling robots or to replace them with a simple transfer device. This significantly reduces the cost.
- Manual set-up can also be simplified.
- Another advantage of the invention is that, if necessary, further set-up work or maintenance work on the spindle and the clamping device can also be simplified by the more accessible set-up position.
- the set-up position is preferably outside the working space and the housing of the device.
- the set-up position can also be used to change the spinning tool, which is attached to the spindle, to pretreat the workpiece, such as heating, or for other functions.
- a preferred development of the invention consists in that the exchange unit has the rotary drive.
- the entire exchange unit with the rotary drive can thus be moved between the set-up position and the flow-forming position.
- the supply lines for the rotary drive are designed to be flexible accordingly.
- a particularly fast set-up is achieved according to the invention in that a first change unit with a first spindle and a first clamping device and at least one second change unit with a second spindle and a second clamping device are provided and that the first change unit and the at least second change unit alternately between the forming position and the set-up position are adjustable.
- An exchange unit can be located in the forming position in the machine, with workpiece processing being carried out.
- the second exchange unit is outside the machine's work area in the set-up position.
- a machined workpiece can be removed and a new workpiece to be machined can be inserted into the clamping device of this exchange unit.
- a set-up and non-productive time of the machine becomes a processing or main time of the machine combined. This increases the degree of utilization of the machine considerably.
- the two exchange units are exchanged so that further machining can be started immediately.
- more than two exchange units preferably three or four exchange units, can also be provided.
- a preferred embodiment of the invention consists in that the at least one interchangeable unit is mounted such that it can be moved linearly.
- one set-up position can be provided on both sides of the device.
- at least one first exchange unit is always moved to a first set-up position, while the at least one second change unit is moved from the forming position into a second set-up position, which is spaced from the first set-up position.
- the at least one interchangeable unit is pivotably mounted.
- two exchange units can be moved back and forth like a revolver about a pivot axis by rotating between the pressure roller position and the set-up position. This enables a particularly quick change.
- exchange units can be provided, which can be moved independently of one another.
- a particularly efficient embodiment of the device according to the invention is achieved in that the first interchangeable unit and the at least one second interchangeable unit are arranged on a common adjusting element.
- the common adjustment element can be a linearly displaceable slide or a pivotable turntable.
- the at least two exchange units can be moved and adjusted at the same time by a single alternating movement and a single adjusting drive.
- the workpiece can be reclamped from the first interchangeable unit to the second interchangeable unit.
- a first pressing tool can be provided on the first exchange unit and a second pressing tool, which are different from one another, can be provided on the second exchange unit.
- the workpiece can initially be clamped in the first spinning tool, with a first side being machined or a first forming step is carried out.
- the workpiece can then be transferred to the second exchange unit in the set-up position manually or, preferably, by an automatic clamping device.
- the workpiece is held on the second spinning tool so that a second machining step can be carried out. This saves the use of intermediate storage or inflexible multi-station machines.
- the exchange units can also be in the set-up position at the same time or at different times.
- the device can thus be used as a flexible multi-station machine. Depending on the workpiece, the device can process two different workpieces as a single-spindle device or, as a multiple-spindle device, process a single workpiece in a progressive manner.
- the transfer is preferably carried out by loading and unloading using conveyor belts with a selectable turning station.
- a further development of the invention consists in that the axis of rotation is arranged horizontally or vertically.
- the changing device according to the invention can be used for both spindle arrangements, a vertical arrangement, in particular a hanging spindle arrangement, being particularly advantageous. With such a vertical arrangement, the alternating movement preferably takes place in a horizontal plane.
- a relative infeed of the at least one forming roller takes place through an axial and / or radial adjustment of the forming roller itself. This can be achieved by means of appropriate supports for the individual forming rollers. An axial and / or radial feed movement of the workpiece can preferably also be provided.
- the at least one forming roller is axially fixed in order to carry out the pressure or pressure rolling process, the workpiece being supported so that it can move axially.
- the workpiece clamped on the clamping device is preferably moved axially with the exchangeable unit during the forming process.
- spinning includes not only forming with a change in wall thickness, but is to be understood more generally, so that forming with constant wall thickness, also called pressing, is also included.
- a loading and unloading device is provided at the set-up position.
- This can be a simple mechanism for feeding in and / or removing the workpiece.
- handling devices in particular multi-axis robots, can also be used. Due to the improved accessibility at the set-up position, an infeed and outfeed movement can be carried out relatively quickly without the risk of a collision.
- the workpiece can also be heated by a heating device or the spinning tool can be changed, preferably by an automatic changing device. The tool change can take place in an additional set-up position, which is parallel to the first set-up position.
- the forming rollers are preferably driven, preferably at the same forming speed as the workpiece surface. To do this, it may be necessary to automatically adjust the speed in the process. This can be done, for example, by freewheeling the drive or active speed control.
- the at least one forming roller is mounted on an adjustable roller support and that a roll changing device is arranged on the roller support.
- the roll changing device can in particular be a turret arrangement with a turret carrier on which several different forming rollers are arranged. By adjusting the roller carrier, the desired forming roller can be moved into the processing position. This further improves the variety of uses and reduces idle times for setting up the machine.
- a multiplicity of forming rollers can be provided, which also act simultaneously on the outside and / or inside of the workpiece.
- the method according to the invention for forming is characterized in that the spindle and the clamping device are combined to form an exchange unit, which can be adjusted transversely to the axis of rotation, the exchange unit being adjusted between a forming position and a set-up position.
- the method according to the invention can in particular be carried out on the device described above.
- the advantages mentioned above can be achieved in this case.
- a preferred variant of the method according to the invention is that a first change unit with a first spindle and a first clamping device and at least one second change unit with a second spindle and a second clamping device are provided, the first change unit and the at least second change unit alternating between the forming position and the set-up position can be adjusted.
- the change or exchange movement enables a particularly fast workpiece change or quick set-up to take place. This reduces idle times and increases the main time of the machine. This improves the degree of utilization and the efficiency of the machine and the forming process.
- a particularly efficient change is achieved in that the at least one change unit is moved linearly or pivoted for adjustment between the pressure roller position and the set-up position.
- the linear process can for example take place with an adjusting cylinder, a ball screw spindle or a linear drive.
- a rotary motor or an actuating cylinder with a corresponding linkage to a pivoting mechanism can be used for pivoting.
- the workpiece can be axially fixed during the forming process, while the forming rollers run over it axially.
- the at least one forming roller is axially fixed in order to carry out the forming process, the workpiece being moved axially. Since the workpiece is already mounted on a movable interchangeable or traversing unit with the spindle, this interchangeable and traversing unit can also be used for spinning to move the workpiece. In this way, an additional axial movement drive of the forming rollers with the corresponding guides can be achieved.
- strippers or ejectors can be provided for pushing off the reshaped workpiece.
- the ejector can specifically be designed as a displaceable axis.
- the supports for the forming rollers are preferably arranged in such a way that the idle paths are as small as possible.
